Podcasts about Stratigraphy

Send us a textToday on the BioAudio podcast, it's all about dating! (no not that kind). Have you ever wondered how we figure out when things happened way in the past? When a scientist says "it's 100 million years old..." just how did they figure it out?Today I'm talking to Dr. Matthew Jones. He's a paleontologist at Arizona State University and his specialty is fossil mammals (though he admits he was a dinosaur kid). It's often his job to figure out just how old is this rock and he's going to tell us about the science of dating ancient things. Stratigraphy, radioactive clocks, iridium rain and a commit that slammed into the earth. Who knew dating was so risky. 

In this episode, Eric Hsu and Louis Everuss have a discussion about the idea of the Anthropocene, a concept that was originally developed within the field of Geology. Despite it not being formally recognised as a defined geological period in 2024 by the International Commission on Stratigraphy, the Anthropocene continues to feature in various discussions across different fields and sectors of society. But how might sociologists contribute to some of these conversations? Eva Lövbrand et al.'s article in Global Environmental Change put forward some compelling proposals, which Eric and Louis seek to make sense of. Notable in this episode is Eric's retelling of a time he ordered a very small side salad when he was out with friends during high school.

About Patrick Kagan I have built, lead, and grown sales organizations for 30+ years, from fortune 500 companies, to mom and pop organizations. My teams and I have NEVER, NOT ACHIEVED OBJECTIVES in all my years, and that comes from mastering DIFFERENTIATION. My book, "SELL THE DIFFERENCE" is all about the unlimited power and potential of DIFFERENTIATION. Readers have expressed the power of CO-ELEVATING both the sales side of the table and the buying side of the table. The end result is no more lost income opportunities and lost customers. Ultimately, "SELL THE DIFFERENCE" will help to increase incomes, profits, and satisfaction. My podcast, "Sales Hindsights with Patrick Kagan" harnesses all that I have learned in the last 30 years, in terms of sales, leadership, motivation, compensation, self-esteem, and courage, and puts that harnessed knowledge into "Practical Inspiration"...Practical because the wisdom is accessible to all, and easy to remember. If it is easy to remember, it is easy to repeat. Inspiring because of what it unleashes in each person. https://pksolutionsgroup.com/ ------------------------------------------------------ About EVGENIY KHARAM Evgeniy has collaborated with small, medium, and large enterprises, developing a talent for simplifying complex technical information into everyday language and aligning it with business needs.

As you walk through the white gypsum sands of White Sands National Park in southern New Mexico, your footprints will likely be quickly erased by shifting winds. So it's somewhat of a phenomenon of nature that the oldest footprints ever discovered in North America are not only found here — in perfect form, having withstood time and weather — but show that ancient humans lived here much earlier than previously believed.  A research team from the U-S Geological Survey earlier this month strengthened their findings released in 2021 that dated these footprints to as much as 23,000 years old. That finding erased previous theories that humans first arrived in North America some 11,000 years ago, after the end of the last Ice Age.  This week the Traveler's Lynn Riddick talks with key researchers from the U.S. Geological Survey team about their initial analysis of the footprints as well as their follow-up study that confirmed the age dating…and what it all means to our long-sought understanding of human colonization on this continent.

For human beings, Earth is a supremely human place. A world of concrete, steel, glass, plastic, cars, paved streets and highways, and lots of other human beings, generating mountains of waste. Here and there, pockets of nature for human beings.Dutch chemist Paul Crützen coined a term for Earth's human age — the Anthropocene. Crützen proposed that it be declared a new epoch in Earth history, terminating the one geologists say we've been in for the past 12,000 years, the Holocene.This summer, a scientific panel will shift Crützen's proposal up a notch.The Anthropocene Working Group (AWG) was set up in 2009 by a commission of the International Union of Geological Sciences. Its task — defining the Anthropocene, geologically.Crützen's idea was that the Anthropocene began with the 18th-century Industrial Revolution. In 2019, a decade of research under its belt, the AWG decided it actually began around 1950, at the start of what American environmental historian John McNeill dubbed the Great Acceleration, in the wake of World War II; a period marked by massive fossil-fuel burning, resource extraction, pollution, global trade and population growth, and the parallel rise of atmospheric carbon dioxide, surface temperature, biosphere degradation and so on.The AWG's next task was to identify one spot on Earth where the telltale signs of human activity are best observed in mid-20th-century sediments. The technical term for this is a mouthful — a Global Stratotype Section and Point. The more popular one: a “Golden Spike.”To be precise, that Golden Spike would be the thin sequence of layers in a core pulled from the bottom sediments of a lake, bay or estuary, or from a peat bog, ice sheet, coral reef or stalagmite, somewhere on Earth, containing the chemical and material signatures of human activity dating to the mid-20th century. Key among these — spheroidal carbonaceous particles (fly ash) from coal burning, microplastics, heavy metals, isotopes of carbon and nitrogen associated with fossil fuel burning, and radioactive Plutonium-239 from atmospheric nuclear weapons testing that peaked in the 1950s.After years of investigation, the AWG came up with a list of 12 candidate Golden Spikes — in Japan, China, Canada, the US, Denmark, Italy, Poland, Australia and the Antarctic. Each candidate site assembled a scientific team to study their cores in the minutest detail.Francine McCarthy, lead scientist for Crawford Lake, in southern Ontario, is proud of her sedimentary cores.“We do have the best site,” McCarthy said. “I have to accept some kind of maternal pride.”McCarthy has reason to be proud. Crawford Lake has been recording human activities for thousands of years. That's because it's very deep, and its bottom sediments are permanently isolated. Those sediments consist of many layers, laid down year after year, all precisely dated.They record the history of coal burning, the rise of atmospheric carbon dioxide and atmospheric nuclear weapons tests, all peaking around 1950.So do sediments from the Baltic Sea, Japan's Beppu Bay, Sihailongwan crater lake in China and the Śnieżka peat bog at the heart of Poland's polluted “Black Triangle.” San Francisco Bay estuary cores are rich in invasive species, mercury and SCPs. Coral samples from the Gulf of Mexico and Cairns, Australia, are also competitive.The competition is tense. To be chosen as the Anthropocene's Golden Spike, a candidate site must receive 60% of votes from the AWG's 23 voting members. Multiple rounds of voting have taken place over the past year.As the AWG prepares to announce its choice, prominent geologists disagree that the Holocene Epoch ended, and the Anthropocene began, a mere 70 years ago.“In geological terms, that's today. It's just yesterday morning,” said Phil Gibbard, a geologist at Cambridge University. ”We have no clue about, seen from thousands of years in the future, whether this would be more than a blip.”Only time will tell if the Anthropocene is a blip, said Simon Turner, AWG's secretary. Turner, standing in a hallway at University College London, around the corner from the geology department, reflects on the popularity of the Anthropocene idea in nonscientific circles.“The thing with the Anthropocene, people get it,” Turner said. “They get the idea of, like, human activity on the planet. The Holocene … I can probably pull someone over here now and say, 'have you heard of the Holocene?' And they will not have heard of it … and geology is just down the corner, so you would hope someone has.”The Anthropocene Working Group will announce its winning Golden Spike sometime this summer, or in the early fall, in Berlin. Its proposal will then pass up the geo-bureaucratic hierarchy — first to the Subcommission on Quaternary Stratigraphy, then the International Commission on Stratigraphy and finally, the International Union of Geological Sciences.However, approval of that Golden Spike — either as the base of a new epoch, the Anthropocene, or just the latest stage of the Holocene (in which case, it would be named after its Golden Spike; the Crawfordian, for instance) — could take years.

Today we are joined by Dr. Zo Kreager, whom is a trained geologist with a research focus on how geologists visually perceive diagrams and best practices for teaching university level geoscience courses. She has won the outstanding graduate teaching assistant award twice and is currently an Assistant Professor of Geology at SUNY Oneonta.She has published numerous articles like "Seeing Like a Geologist: How Expertise and Context Impact Frame-of-Reference Judgments" & her latest being featured in Geosphere from the Geological Society of Americca about how "Spatial skill predicts success on sequence stratigraphic interpretation." 1. https://www.geosociety.org/gsatoday/groundwork/G423GW/GSATG423GW.pdf2. https://pubs.geoscienceworld.org/gsa/geosphere/article/18/2/750/612178/Spatial-skill-predicts-success-on-sequenceIf you know any women in the STEM field or you yourself would like to be part of this project, please send an email to mindyourstem@gmail.com.Instagram: @mindyourstemFacebook: https://www.facebook.com/MindyourSTEM

There's a lot of debate about the idea that the global changes brought about by humans define a new geological epoch, dubbed the Anthropocene. Should such an epoch be added to the official geological time scale? If so, what aspect or aspects of anthropogenic change should be used, and exactly where do we place the golden spike that will define the base of the Anthropocene? Such questions come under the purview of the International Commission on Stratigraphy, whose current secretary general is our guest in this episode. Phil Gibbard is Emeritus Professor of Quaternary Palaeoenvironments at the University of Cambridge. In 2009, he was a founding member of the Anthropocene Working Group tasked by the International Commission on Stratigraphy to examine the status, hierarchical level, and definition of the Anthropocene as a potential new formal division of the Geological Time Scale. He explains that no consensus on the Anthropocene has been reached, and it remains controversial as to whether there is even a need for such an epoch at all.

The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals. Sequence stratigraphy has arguably revolutionized stratigraphic analysis in the oil and gas industry since the 1970s, but to date, few environmental companies have utilized this power tool. Although many companies have intended on using sequence stratigraphic correlation techniques to define the subsurface heterogeneity, they have mistakenly used lithostratigraphy, significantly limiting their ability to construct accurate CSMs and develop effective remedial strategies. In this seminar, we will leverage case studies to make participants aware of the pitfalls of lithostratigraphy and highlight the role of sequence stratigraphy in generating robust and realistic hydrogeological models.

Between the weird and wonderful rangeomorphs of the Ediacaran Period and the world-famous palaeocommunities of the Burgess Shale, the 'Early Cambrian' is host to a 'waste basket' of fossils untied by their small size and shelly construction. These small shelly fossils (SSFs) aren't just a single group of animals, but represent several different invertebrate phyla. Further compounding the difficulty of their identification, each SSF, termed a 'sclerite', is part of a larger composite skeleton known as a 'sclerotome'. Whilst some complete sclerotomes have been preserved, many SSFs still represent multiple jigsaws thrown together and the pictures lost. Piecing the SSFs back together and building a picture of the Earliest Cambrian is Dr Marissa Betts of the University of New England, Australia. Her work on the SSFs have provided a new framework for the regional stratigraphy of Australia and in this interview, we discuss why this was necessary, how she went about it and finally, what we know about the animals themselves.

We now live in the Meghalayan age—the last age of the Holocene epoch. Did you get the memo? A July decision by the International Commission on Stratigraphy, which is responsible for naming geological time periods, divided the Holocene into three ages: the Greenlandian, the Northgrippian, and the Meghalayan. The one we live in—the Meghalayan age (pronounced “megalion”)—is pegged to a global drought thought to have happened some 4200 years ago. But many critics question the timing of this latest age and the global expanse of the drought. Staff writer Paul Voosen talks with host Sarah Crespi about the evidence for and against the global drought—and what it means if it's wrong. Sarah also talks to staff writer Kelly Servick about her feature story on what happens when biocontrol goes out of control. Here's the setup: U.S. Department of Agriculture researchers wanted to know whether brown marmorated stink bugs that have invaded the United States could be controlled—aka killed—by importing their natural predators, samurai wasps, from Asia. But before they could find out, the wasps showed up anyway. Kelly discusses how using one species to combat another can go wrong—or right—and what happens when the situation outruns regulators.

Check out the others here: Episode 23 - Atmospheric Physics with Dr. Joanna Haigh Episode 24 - Theoretical Ecology with Dr. Emily Moberg Episode 25 - Ocean Corals and Climate Change with Dr. Jessica Carilli Envirothon - Environmental resources research competition for highschoolers Related Headline: Sea level rise in 20th century was fastest in 3,000 years, Rutgers-led study finds Rutgers Department website where Jennifer is completing a PhD   Research concepts discussed with Jennifer on episode 26 Proxy - "In paleoclimatology, or the study of past climates, scientists use what is known as proxy data to reconstruct past climate conditions. These proxy data are preserved physical characteristics of the environment that can stand in for direct measurements. Paleoclimatologists gather proxy data from natural recorders of climate variability such as tree rings, ice cores, fossil pollen, ocean sediments, corals and historical data. By analyzing records taken from these and other proxy sources, scientists can extend our understanding of climate far beyond the instrumental record." Foraminifera are a species that are used as proxy indicators for scientists like Jennifer to study historic sea level changes. "Foraminifera (forams for short) are single-celled protists with shells. Their shells are also referred to as tests because in some forms the protoplasm covers the exterior of the shell. The shells are commonly divided into chambers which are added during growth, though the simplest forms are open tubes or hollow spheres. Depending on the species, the shell may be made of organic compounds, sand grains and other particles cemented together, or crystalline calcite." You can read a peer-reviewed article about that here. Sediment Stratigraphy - "The branch of geology that seeks to understand the geometric relationships between different rock layers (called strata), and to interpret the history represented by these rock layers." Marsh - "A marsh is a type of wetland, an area of land where water covers ground for long periods of time. Unlike swamps, which are dominated by trees, marshes are usually treeless and dominated by grasses and other herbaceous plants. Herbaceous plants have no woody stem above ground, and they grow and die back on a regular cycle. Herbaceous plants can be annuals (which grow anew every year), biennials (which take two years to complete their life cycle), or perennials (which take more than two years to complete their life cycle.) Marsh grasses and other herbaceous plants grow in the waterlogged but rich soil deposited by rivers. The plants roots bind to the muddy soil and slow the water flow, encouraging the spread of the marsh. These watery pastures are rich in biodiversity. There are three types of marshes: tidal salt marshes, tidal freshwater marshes, and inland freshwater marshes. Marshes are also common in deltas, where rivers empty into a larger body of water. Although all are waterlogged and dominated by herbaceous plants, they each have unique ecosystems." Glacial isostatic adjustment - the ongoing movement of land once burdened by ice-age glaciers.

Dustin Sweet is an Assistant Professor of Sedimentology and Stratigraphy in the Department of Geosciences. He discusses what fossil soils can tell people about the history of climate in the Southern Plains. He explains the physiography of the southern plain. He shows a variety of tools of what you can use to study past climates by looking at the weathering ratios. With these ratios a person can look at the soil and see the conditions they were in. His team studied the soil in the Southern Plains and found that in the past decades the soil was much wetter and now it has become very dry.
