Et pourtant, ce projet est bien réel. Il est actuellement étudié au Royaume-Uni, au sein du National Oceanography Centre de Southampton, dans l'objectif d'augmenter la capacité des océans à absorber le dioxyde de carbone (CO₂).Une arme contre le réchauffement climatique ?Comme les forêts, les océans sont d'immenses « puits de carbone ». Ils captent près d'un tiers des émissions humaines de CO₂. Mais selon un rapport de la National Academy of Sciences britannique publié en 2021 — récemment remis en lumière par le magazine NewScientist —, cette capacité pourrait être augmentée de 8 % grâce à une intervention géochimique inédite.L'idée ? Verser jusqu'à un million de tonnes d'olivine broyée — un minéral naturel de couleur verte composé de magnésium, silicium et oxygène — dans certaines zones stratégiques des océans. En se dissolvant dans l'eau salée, l'olivine réagit chimiquement avec le CO₂... Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

The islands of the Pacific Ocean are on the frontline of climate change. Sea level rise will eventually erase some from the map and make many more uninhabitable. Tom Heap and Helen Czerski hear from the people of the region and explore its stunning wildlife both above and below the waves.With them in the studio are Professor Tammy Horton from the National Oceanography Centre in Southampton and BBC One Show naturalist, Mike Dilger. Tammy studies- and names- some of the thousands of creatures recently discovered living at depths of 4-6km in the Pacific's Clarion Clipperton Zone, while Mike has just returned from the bird-watching trip of a lifetime, spotting the extraordinary Birds of Paradise of Papua New Guinea.Samoan climate journalist Lagipoiva Cherelle Jackson joins in the conversation to consider how Pacific islanders respond to the prevailing narratives around climate change. She says that the islanders have no wish to be presented as victims and are well placed to stand up for their rights in international climate negotiations and to actively lead efforts to maintain their rich cultures, despite the rising tides.Producer: Alasdair CrossAssistant Producer: Toby FieldResearcher: Harrison JonesRare Earth is produced in association with the Open University

Durham University scientists have made a groundbreaking discovery in marine geoscience, revealing unprecedented insights into the dynamics of Earth's longest-runout sediment flows. By using seabed seismographs placed safely outside the destructive paths of powerful underwater avalanches of sediment, researchers have successfully monitored turbidity currents - a natural phenomenon that shapes deep-sea landscapes, damages telecommunication cables, and transports large quantities of sediment and organic carbon to the ocean floor. The longest runout sediment flows on earth The study recorded two massive turbidity currents that travelled over 1,000 kilometres through the Congo Canyon Channel, moving at speeds of up to 7.6 metres per second. These flows lasted over three weeks and marked the longest runout sediment flows ever directly observed on Earth. This achievement provides critical new data on the duration, internal structure, and behaviour of turbidity currents, advancing our understanding of this powerful geophysical process. This breakthrough opens up new possibilities for studying one of the most significant yet poorly understood processes shaping our planet. By using ocean-bottom seismographs, researchers can now safely and effectively measure these extraordinary events in more detail than ever before. Lead author of the study, Dr Megan Baker of Durham University, said, "This multidisciplinary work brought together geologists, seismologists, and engineers to advance our understanding of powerful turbidity currents through first-of-their-kind observations using ocean-bottom seismographs. "This approach enables the safe monitoring of these hazardous events and will help us learn where and how often turbidity currents occur globally." The research team, which included researchers from Newcastle University, GEOMAR Helmholtz Centre for Ocean Research, National Oceanography Centre, Georg-August-University, Deutsches GeoForschungsZentrum GFZ Potsdam, IFREMER, Université Paris-Saclay, TU Wien, University of Hull, University of Southampton and Loughborough University, successfully used ocean-bottom seismographs - instruments that are placed on the seafloor to record seismic signals generated by the turbidity currents. This innovative approach allowed the researchers to capture detailed information on these flows without risking damage to expensive equipment, as has been the case with previous attempts. The use of these seismographs marks a major step forward in monitoring hazardous seabed events, offering a cost-effective and long-term method for studying turbidity currents and their impacts. The findings also reveal the global significance of these underwater flows. The turbidity currents studied in this research not only shape deep-sea landscapes but also play a crucial role in the transport of organic carbon and sediment to the ocean floor, with significant implications for deep-sea ecosystems and global carbon cycles. The study shows that despite substantial erosion of the seafloor, the front of these massive flows maintains a near-constant speed and duration, efficiently moving organic material and sediment vast distances to the deep sea. The study also challenges traditional models of turbidity current behaviour, suggesting that the flows can maintain a consistent speed and duration even as they erode the seabed. This finding calls for a revaluation of existing models that have been based primarily on shorter, shallower flows.

Last year's volcanic eruption in Tonga triggered the fastest underwater debris flow ever recorded - at 122 kmph. The research, by NIWA and the UK's National Oceanography Centre, sought to find out how the eruption of Hunga-Tonga Hunga-Ha'apai had broken underwater telecommunications cables 80-kilometres away on the seabed. When the volcano blew, it spewed rock and ash 57-kilometres into the mesosphere. It was when some of that material returned to earth that it rapidly spread out deep underwater, smothering everything in its path. NIWA marine geologist and voyage leader Kevin Mackay spoke to Corin Dann.

Huge robots, including a seven-metre two-tonne vessel named Ran, are on their way to the Thwaites Glacier to learn more about the retreating ice and its impact on Climate Change. But this won't be the only tech that's being deployed on the 65-day mission; British Antarctic Survey's Boaty McBoatface and the Autosub Long Range vehicle operated by the National Oceanography Centre in the UK, will travel under the ice shelf along with Ran. Professor Anna Wåhlin from the University of Gothenburg tells us more about her robot Ran and about the data she'll be collecting. Tiny light engines We're talking to Ed Tang, the CEO of Avegant. They're the company behind the world's smallest light engines for augmented reality. Developing projectors thinner than the width of a pencil means we're on the brink of AR glasses that will barely look different from standard glasses. Alongside talking about how this technology works, Ed also spoke to us about what this means for the future of AR. James Webb telescope tech Space journalist Kate Arkless-Gray is live on the show to tell us about the tech that got the James Webb Telescope into space and how vital it is that none of the tech deployed goes wrong - unlike the Hubble space telescope, repair missions to James Webb are impossible. The programme is presented by Gareth Mitchell with expert commentary from Ghislaine Boddington.

This episode looks at attracting youngsters into shipping with an apprenticeship focused on autonomy and unmanned ships and how technology can be the eyes and ears of a ship officer on the bridge (as a proposed electornic lookout function).WithGordon Meadow, CEO, SeaBot XREero Lehtovaara, Head of Regulatory Affairs, ABBIndustry updates fromNick Chubb, Founder, ThetiusHostCraig Eason, Fathom.WorldFull transcript belowCraig Eason Hello and welcome to the Aronnax Show. This is a podcast looking at the shipping and maritime space. I’m Craig Eason, and I own and edit the Fathom World news site focused on the changing aspects of our industry.I’ll tell you something about myself quickly. I’m an ex-seafarer. I worked as a navigation and deck officer, deep sea on the bridge of many different ship’s and it was a career I was and still am proud of, even if I did not do what so many of my fellow apprenticeship friends did at the time and go on to become master mariners. I chose to go into journalism instead.Over the years the role of the mariner has changed. You can see many articles on Fathom World and find episodes of the Aronnax Show about this transformation as new levels of connectivity and technology have developed. Society itself is trying to tackle this change too, and we have a range of discussions in many corners of many of our industries about autonomy, autonomous systems and so on.Now, I’ve quite often railed against those headlines that state that fleets of ghost robot ships are coming. These are sensationalist headlines. Reality has never got in the way of a good headline.But having said that, the way technology is going and with the discussions at the International Maritime Organization on which regulations prohibit their appearance, we know that something is changing. What is happening though is technology is creating a new dynamic onboard vessel, and yes, they may coalesce into increased autonomy, and even unmanned ships in some corners in the future. But today on this episode of the Aronnax Show I want to look at two things that are happening that are more immediate next steps.Two things are happening on a regulatory front now that I think make a big difference. The first is a pair of submissions that are going into the regulatory body the International Maritime organization that is asking it to consider the idea of an electronic lookout function, something that those supporting the idea believe is a required part of having periodically unmanned ship bridges. And the word ‘periodically’ is important here.The proposal has a lot to do with all round video cameras and elephant ears on a ship. More on that later (Pause)Now, my cadetship was in the 1980’s It involved learning morse code, and how to use Decca and even Loran-C. I remember sat in a former world war military bunker style building in Plymouth England looking at the swirling green radar screens and a Decca chart with its multicoloured tramlines. And yes, the sextant. That’s all history or nearly all, history.Today’s apprentice in the UK still must learn about seafaring and some of the skills of electronic navigation.But it’s getting even more complicated, and now there’s the growing awareness of autonomy. So how do we get kids to leave school and join an industry which on the one hand has been an unpopular choice in recent years, but has the potential to be so so different.In the UK, a group has come together to look at how an apprenticeship can be developed that caters for this. It’s looking at the development of a new type of apprenticeship bearing in mind the increased amount of autonomy that is appearing in civilian and naval craft. That’s not just autonomy on the ship for onboard crew, but also for remote operations. The group was announced last month and consists of the UK’s Royal Navy, the geo-data company Fugru, the UK’s National Oceanography Centre, marine robotics business Ocean Infinity. And it is being chaired by UK advanced training business Seabot XR.Gordon Meadow, CEO Seabot XR told me about the plans and why it is important:Gordon Meadow, SeaBot XRThe apprenticeship is a response in industry need. Operators want to operate in a responsible way, and they have a workforce that has been built on experience at sea, and they're now being given the opportunity to use autonomous systems and new ways of working. So, there's a gap, and this apprenticeship will look towards identifying that skills gap, mapping those competencies and creating a new workforce with more enhanced skills, but this is simply about training the people who are going to be operating vessels today, not about the future, not about, you know, sort of this kind of fanciful idea that, you know, all ships will be autonomous in the next 10 years. This is this is simply about taking a responsible approach to the migration of the workforce, and the workforce is underpinned by seafaring and STCW qualifications - really that's paramount that experience. Now projecting forward 30 -40-50 years any occupation will change, you know, any occupation will change will you need to have gone to see in 50 years’ time, who knows? Bu for the time being the key migration is of this is the current and existing maritime workforce and that knowledge that neds to come with it - that experiential knowledge.Craig EasonNow autonomous craft that the apprenticeship group are looking at are up to around 24 m in length, but there are plans to go bigger, with Ocean Infinity, one of the apprenticeship development group partners already looking at 70 m vessels This apprenticeship looks at it from an operational point of view from how you control them, how you maintain control, maintenance issues.It's important to realise that this programme to develop an apprenticeship is not about international shipping, that requires, as Meadow says work at the IMO on the seafarer training requirements. Many people agree that these need updating, but it would be an enormous task as any changes need to encompass shipping for today as well as the future, and everywhere in the world.Gordon Meadow, SeaBot XRThis UK apprenticeship isn't, isn't based on developing international standards around the world. This is responding to responsible operators operating their craft in and around UK waters and more broadly. But this will capture the operators’ requirements, which we can then feedback up through the system, for the likes of the maritime and Coastguard agency and say look, actually, these are the competencies we have identified through this group. There's also a top-down approach where the MASSPpeople group was launched - I think two weeks ago now - where to Seabox XR, Fugru and the Maritime & Coastguard Agency are founder members. That group consists of a number of flag states and which will look at the standards required internationally, and try and benchmark those standards, and then share those standards, and create new standards and then create recommendations to go to IMO and say, "Look, this, these are the recommendations, we think that should be added in terms of competencies to STCW". Craig EasonIn my interview with Gordon Meadow, he kept the focus on the people, and the need to ensure it is about skills, not systems, robots and software. In his opinion we all need to challenge a rhetoric that machines are good, and the human is bad. Seafaring skills remains as crucial as ever.But it is about a migration of the workforce, about writing down the new skills that existing seafarers will need.Gordon Meadow, SeaBot XRAnd that's, I guess, that's, that's being looked at, to some extent separately, by the you know, but by Maritime UK, they MNTB and that the Maritime Skills Commission, we’re interested in looking at a particular new developing occupation, which is quite a sexy occupation. I think, you know, I think I have always found it to my amazement, that the, there's this sea blindness, and I think, I think they're really trying to make an effort are really trying to make an effort in the UK to be able to remove this Sea blindness and make the industry more attractive to young people and help them to help them to realize that it's there, and this has huge potential and huge, huge opportunity for careers. I know that one champion, one person showing this is Sarah Kenny, from BMT. She's really trying to shine the light and shine a light on this. So, for me, there is a huge, huge opportunity for young people on this to get into a career that would be, you know, a fascinating career to get into it's a new avenue into maritime, and it's also a new avenue into maritime, which would provide perhaps a similar appetite to get involved in for both men and women. And there's two there's a there's a, there's kind of there's a gender equality issue too, as well. And as well, I think there are other opportunities from other people in other sectors who may not have considered career maritime before such as those, you know, those not perhaps seen as physically able to be able to perform. You know, it's not mandatory to to fit a wheelchair ramp on a ship necessarily, but it will be on a remote operation centre. So, so there are lots of opportunities for new entrants into it. I think, with some of the underlying skill requirements you will need as operations centres move forward. And the complexity of them, it will attract other people in the industry. And will there be jobs? Yes, there are because there's already a massive shortage in the industry of seafarers, as we as we will know. So, will there be jobs going forward? Absolutely. Craig EasonGordon Meadow from Seabot XR on the evolution of the seafarer and a new breed of people who will need to work in operation centres, ones who will not necessarily need to walk on the deck. Now while Meadow says these UK initiatives on training and apprenticeship are focused on the new generation, there is still the existing workforce at sea, those spending months on end on a ship. Those on a bridge watch spend those months with a broken sleep pattern, four-hour bridge watches once every twelve hours, with other duties expected to be completed in the non-watch periods. And this is where the idea of a Bridge Zero function first materialised. Yes it can be seen as a step towards unmanned ships, but it has its initial purpose on welfare and safety.It is the idea that under certain times a bridge can be left unmanned while the vessel is underway. Those conditions would have to be very specific- clear visibility, good weather, zero traffic in the proximity etc. Now to allow that situation to be permitted the International Maritime Organization is being asked to accept technology as a suitable replacement for the eyes and ears of the watch officer or a watchkeeper.The proposal is going to come from the European Union into IMO’s Maritime Safety Committee, but the idea has been developed in Finland.One of the proponents is Eero Lehtovaara, who is head of regulatory affairs at engineering firm ABB.I have spoken to Eero, a former maritime officer and captain, many times of the years as the ideas for autonomy have developed, looking at how digitalization and autonomy can increase safety for those onboard as opposed to the idea of taking people off the ship.It is an important distinction for Eero and helps frame the discussion. Is digitalisation and autonomy about unmanned ships per-se, or about increased safety and welfare for those on the ship? Eero Lehtovaara ABBIf we're starting to, to do something that will even at some level substitute the human, even if it will be for a shorter period of time, we need to be first of all, we need to be sure that we are right that it's actually better. But then we know that that is something we call the social licence to do to to operate. Meaning that you and I, when we see technology, we expect that technology to be way better than what we can do. And there's this kind of expectation, meaning also that on a modern-day cruiser, or car carrier, you could say that you don't have the best visibility straight behind you. There will be an expectation of full coverage of 360 degrees, and continuous scan and so on. We also learned and this is obviously something where we talk about the scientific research that is far outside of our area of competence. I mean, ophthalmologists, who research the eye, and so on, so we used material that we can find on the subject. And then it was quite interesting in the sense that, first of all, if we are focusing the eyes somewhere, we physically tend to lose everything around us. And you can only focus. I mean, if you're focusing somewhere far, then you tend to lose things that are happening close and vice versa, and so on. Also, if you're focusing on a point far ahead, you're not only lose movement and seeing on the periphery, but that you're very early, also starting to lose colours, which was news for me. Meaning that if you have a theoretical situation where you have a ship coming against ahead of you, or you're in a collision course head-to-head, you focus on that ship. That means that you stop seeing things around you. Obviously with machine learning machine machines doing that, you would not have that issue because they would monitor continuously around you.Craig EasonAnd this is where Elephant Ears and the Snellen chart – you know it as that pyramid of letters at the opticians that decrease in size as you read down. For an optician, a person with normal eyesight has an eight on the Snellen scale and a seafarer must pass an eye test and get more than five. Hearing is also tested.Now hearing is one area where the regulations already allow for technology. This is the Elephant Ears. Quite a few ships are built today with totally enclosed bridges, that means the bridge wings are not out in the open air. One of the requirements under international rules is for ships to have specific audio signals (such as in fog) and an officer or watchkeeper in a totally enclosed bridge will be unable to hear those signals. Hence the development of a technology that is basically a microphone outdoors feeding into a speaker or alarm system indoors.Eero Lehtovaara points to this as a first step in how the electronic lookout function would work, as this and the required cameras that would point all around a vessel would be coupled to a system capable of recognition that there is something there and then sounding the alarm.Eero Lehtovaara ABBWe talk about three different levels or stages. What they are calling the DRI - the detection, recognition and identification. And what we presented in the electronic lookout function is really the D part -detection. So, the aim is to detect that there's something else outside than water. Period. In its lowest level that will make an alarm, and someone, a human will come up and then make the recognition and the identification and after that the decisions. I mean, at this stage, I would say that machines are better today at detecting than people are, but people are way better in recognition than the machines are today and able to make conclusions and take that further into decisions and in actions. So, obviously, we see that if you're ever going to have an unmanned ship, they need to be able to do all of these, based on first detection, what is it what it's going to be doing? How is that reflected into col-regs and so on and so on. But at its lowest level, in order to be able to fulfil the requirements of B-0, just detection is enough. If we can detect that there are things there, then we get the alarm, and somebody is coming to the bridge. And then we will be able to make the necessary right decisions thenCraig EasonEero Lehtovaara on the possible way a manned ship could occasionally sail with an electronic lookout function allowing for a bridge or wheelhouse to be unmanned, while the watchkeeper and officer of the watch do other things.While this potential work at the IMO on the electric lookout function may be for a stand-alone alarm system connected to the OOW who remains on standby if an alarm sounds, there is no doubt this function can be connected to other bridge technology. In its simplest form it is a series of high-resolution cameras giving an overlapping 36o degree coverage of a ship potentially as far as the horizon, going forward this can be part of the further digitalisation of a ship to give even greater situational awareness, with the lookout function an integral part of a digital sensing brain also linked to the radar, GPS, electronic displays and charts as well as other systems.There are smaller vessels already doing this, just look at the Mayflower project with an IBM brain inside is.ENDS Support this show http://supporter.acast.com/aronnax.

Last weekend a joint European-US satellite blasted into space to begin its mission - monitoring the oceans back here on earth. Sentinel 6 Michael Freilich is one of a long line of satellites and has a striking design – appearing like a bright gold farmyard barn with a big pitched roof. Anand Jagatia speaks to Dr Ralph Cordey at Airbus Space and Defence about the latest design iteration and the technology on-board. Oceanographer Professor Penny Holiday from the National Oceanography Centre explains how Sentinel 6’s readings will enhance understanding of sea-level rises and give more detail about the currents in our oceans. We journey back to the cosmic ‘Dark Ages’, a period of time that we know hardly anything about. Dr Emma Chapman is an astrophysicist at Imperial College London who has written a book ‘First Light: Switching on Stars at the Dawn of Time’ to throw light on this illusive chapter in the history of our universe. How close are scientists to finding the first stars? With ambitious new government targets to end the sale of petrol and diesel cars by 2030 how ready are electric cars to fill the gap? One key area many companies are trying to improve are the batteries powering electric vehicles. Peter Bruce, professor of materials science from Oxford University and chief scientist at the Faraday Institution has been working on rechargeable lithium ion energy storage since the 1990s. He speaks with Anand about the current limitations and the most recent developments in battery research and development. Presented by Anand Jagatia Produced by Melanie Brown

Dr Adam Rutherford uncovers the worrying number of false positive results that the DNA sequencing technologies used by 'direct to consumer' genetic test kits are producing. Many of these tests offer analysis on your ancestry, but some also offer to check you out for the likelihood of you being at risk of some genetic diseases like cystic fibrosis or certain types of breast cancer. The tests look for variants in your genome, little changes in your DNA that alter the risk of developing a number of genetic diseases. The trouble is the rarer the variant, the more likely it is to be disease-causing. But the rarer the variant, the more likely the simple genetic tests are to get it wrong. And with more and more people sending off their raw genetic data to third-party websites for analysis and annotation, the risk of a false positive result increases to up to 80%. It's a small number of people affected, but a serious one if you're told out of the blue that you are at extreme risk of a serious disease. The advice is to keep an eye on family disease traits and if you are worried, go and see your doctor and get a proper diagnostic test. Deep sea pelagic sharks, like the great white, silky, tiger, porbeagle and blue are much more vulnerable than their scary reputation suggests. In fact, many shark species are in decline as a result of industrial fishing rapidly encroaching upon their territories, and an increased value of the sharks themselves. The oceans are big and sharks range far and wide, so understanding these movements is not easy. Professor David Sims, from the Marine Biological Association of the UK and the National Oceanography Centre in Southampton, is part of a huge international consortium of marine biologists who have been tracking 11 species of shark all over the high seas using satellite technology. We’ve been fishing for more than 40,000 years, but our exploitation of the seas got serious in the last 50 years. In nature, sex can be quite fluid, and in some species, sex changes are just a normal part of every day life. Especially in fish. This type of behaviour is called sequential hermaphroditism, and is common in fish. It's been known about for years, but the underlying genetic mechanisms are mysterious, which is strange for such a radical transformation. In the Blueheaded wrasse, when a dominant male is lost from the shoal, the largest female will immediately begin transforming into a male. Neil Gemmell from the University of Otago in New Zealand has lead a study which for the first time has uncovered the genetics of how the sex change happens. Producer: Fiona Roberts

Last weekend a chemical ‘haze’ on the East Sussex coast saw 150 people needing hospital treatment after something in the air led to streaming eyes, sore throats and nausea. Leading theories so far include a chemical spill from shipping in the English channel, a localised spike in ozone levels and an algal bloom, where algae suddenly proliferate and release harmful gasses. Dr Simon Boxall of the National Oceanography Centre at the University of Southampton tells Gareth Mitchell why he’s favouring the algal bloom theory. We know about extinct species from fossils in rocks. But in the future there will be techno-fossils too, evidence of our civilisation. Katie Kropshofer has been finding out from Professors Jan Zalasiewicz and Sarah Gabbot of the University of Leicester what we’re leaving for the hypothetical geologists of the future. Neuroscientist Joseph Jebelli's book, In Pursuit of Memory: The Fight Against Alzheimer's, is the one of the six titles on the shortlist of the Royal Society Insight Investment Science Book Prize. He explains to Gareth Mitchell that it was his grandfather's development of the condition that made him interested in Alzheimer’s. The Big Wasp Survey is a citizen project to trap wasps and send them off to teams at the University of Gloucester and University College London, so that scientists can then learn more about the distribution of different species around this land. One of the organisers, entomologist and professor of Science Communication at the University of Gloucester Adam Hart, talks to Gareth about why these unpopular insects are ecologically valuable.

The government has announced that tiny pieces of plastic in personal beauty products that end up in the oceans will be banned from sale in the UK. But given their size how much of a problem are minuscule bits of plastic to marine life? Gareth Mitchell meets Professor Richard Thompson of Plymouth University to uncover the marine biology concerns that have led to the micro bead ban. However much we watch animals in the wild we can't really know what they get up to. Rory Wilson, Professor of Zoology at Swansea University, has found a way to eavesdrop on animals that live in remote parts of the world and he's revealed some of his latest discoveries at the British Science Festival in Swansea today. He's developed a logging device that collects a whopping amount of data - 400 items each second. His daily diary collects amongst other measurements, location, magnetic field, temperature, and pressure. Before his talk, Adam Rutherford went along to Rory Wilson's lab and found out which animals he's attached the logger to and discovered their secret life. In the final entry of this year's shortlist for the Royal Society book prize Jo Marchant discusses Cure - which examines how the mind plays a crucial role in health. Our thoughts, emotions and beliefs, it seems, can ease pain, heal wounds, fend off infection and heart disease and even slow the progression of AIDS and some cancers. So what is the potential of the mind to heal - and what are its limits? As many as 530 key infrastructure sites across England are still vulnerable to flooding, according to a government review out today. Southampton University researchers want to understand better how floods happen and how to predict them. Beyond burst river banks and breached defences, they're building up a more detailed picture, house by house, and street by street of what happens when water levels rise. For that they need data, lots of it going back as far as possible. Ivan Haigh at the National Oceanography Centre and his colleagues are pulling all kinds of photos and records together in an interactive multi-purpose online shared database called Surgewatch. Presenter Gareth Mitchell Producer Adrian Washbourne.

Dr. Chris Rowan is an Assistant Professor in the Department of Geology at Kent State University. He received his Masters Degree in Earth Science from the University of Cambridge and his PhD in Geology from the National Oceanography Centre of the University of Southampton. Afterward, Chris worked as a Research Technician at the National Oceanography Centre in Southampton. He then served as a Postdoctoral Researcher at the University of Johannesburg, a Marie Curie Fellow at the University of Edinburgh, and a Canadian Institute for Advanced Research Postdoctoral Fellow at the University of Chicago before joining the faculty at Kent State. Chris is here with us today to tell us all about his journey through life and science.

Brian Cox and Robin Ince return for a new series of the award-winning science/comedy show, as they take a witty, irreverent and unashamedly rational look at the world according to science. In today's programme they'll be looking down rather than up as they consider the great mysteries that still remain uncovered in the watery depths of our oceans and asking whether they are truly the last unexplored frontiers for science. It has often be said that we know more about the surface of the moon than we do about much of what lies beneath the ocean waves, so how come we know so little about the vast majority of our own planet? They'll be joined on stage by comedian Dave Gorman, British Antarctic Survey scientist Lloyd Peck and Bramley Murton from the National Oceanography Centre in Southampton. Presenters: Robin Ince and Brian Cox Producer: Alexandra Feachem.

Who Owns Underwater Cultural Heritage?

Scientists know that fluffy stratocumulus clouds act like a blanket on the Earth - they stop warm air escaping, but also reflect the Sun's energy back out to space. But they have no idea if cirrus clouds, which are high up in the atmosphere and made of ice, do the same. So Dr Paul Connolly makes ice clouds inside the 10-metre-high, three-storey ice cloud chamber - which looks a bit like a giant fridge freezer - to find out.
