EARTHx | Alumni All-Access Presentation: The Ice Age Time Traveller
Placer gold miners discovered a mummified baby woolly mammoth (Mammuthus primigenius) in the Klondike region of the Yukon in the summer of 2022. Its discovery and rapid recovery was made possible because of the strong relationship between Yukon government scientists and the mining industry.
The mammoth was given the name Nun cho ga by the Tr’ondëk Hwëch’in First Nation, which means “Big animal baby” in the Hän language. They have also assumed a guardianship role of this mammoth and, importantly, introduced Indigenous spirituality to the discovery.
Travel back in time and learn about the discovery of Nun cho ga, our current understanding of the mammoth, the landscape it inhabited, and its mechanism of preservation. You'll also learn more about how important it is that the Tr’ondëk Hwëch’in First Nation uses culture as a leadership foundation when caring for ancient ancestors.

It is widely known that the Antarctic ice sheet is melting and contributing to sea level rise. Far less understood is why this is happening now. This is not a simple case of a warmer climate: air temperatures remain well below freezing all year in all but the most northerly parts of Antarctica. Antarctica is primarily melting from below, where relatively warm ocean water is the underside of ice shelves (the floating part of a glacier when it reaches the sea). Yet, the water itself is not much warmer than it has always been -- the ocean surrounding Antarctica has probably warmed only about a tenth of a degree in the last century. So, what is going on? The available evidence suggests that a complex interplay between winds, sea ice, ocean currents, and the geometry of the melting ice itself, has gradually increased the efficiency with which warm water reaches and melts the ice shelves. Ice core records have played a key role in our understanding of these processes, because they stretch back farther in time, beyond the instrumental record of Antarctic climate that began only in the late 1950s. The beginning of accelerated melting that we observe today probably began earlier, in the 1940s. Remarkably, the distant tropical Pacific Ocean has played a key role.
Eric Steig is Professor and Chair of the Department of Earth and Spaces Sciences, and Adjunct Professor in Atmospheric Sciences, at the University of Washington. He earned his Bachelors in earth sciences in 1988 from Hampshire College, and his PHD from the University of Washington in 1996. He was research scientist at the University of Colorado and then Assistant Professor at the University of Pennsylvania for three years, before returning to the University of Washington in 2001. His focuses on climate and ice sheets, using a combination of isotope geochemistry and climate modeling. His primary observational tool is the ice itself – ice samples obtained by drilling cores into the ice sheet, which are brought back to the lab and analyzed. His primary analytical tools are isotope-ratio mass spectrometry and laser spectroscopy, often using instruments and methods he and his laboratory staff and students have pioneered. Eric was honored as a Fellow of the American Association for the Advancement of Science in 2019, in recognition of his polar climate and glaciology research and for being an early innovator in public communication about climate science. In 2023, he was elected Fellow of the American Geophysical Union for “numerous fundamental contributions in ice core, paleoclimate, and climate dynamics research.”

Over a decade ago, our research team ventured into the deep Pacific Ocean near Costa Rica. At depths of 3000 meters, our mission was to sample fluids emerging from the ocean crust. Our primary ambition? To uncover the secrets of the microbial communities inhabiting the ocean crust, pinpointing the chemical reactions that allow them to flourish, and extrapolating these findings to potential life in other ocean worlds like Enceladus and Europa.
Earlier research in this region identified 11 unique outcrops emerging from the impermeable sediments, facilitating water interchange between the ocean and its crust. Intriguingly, a staggering 80% of the crustal heat in this region appeared to be unaccounted for. The dominant theory proposed that vigorous hydrothermal circulation was responsible for this vast heat discrepancy. Eager to corroborate this, our quest led us to the anticipated fluid flows at the enigmatic Dorado outcrop.
When our robotic emissary reached Dorado, it unveiled a breathtaking spectacle: a thriving oasis teeming with biodiversity. Most astonishingly, over a hundred brooding octopus nestled in crevices, laying their precious egg sacs in the warm, shimmering water cascading from this underwater pinnacle. In this unexpected turn of events, we had stumbled upon the world's first known deep-sea octopus nursery, a revelation even we were unprepared for and initially unequipped to fully comprehend.
A decade later, armed with renewed funding, a revamped team, and a state-of-the-art vessel, we revisited the mesmerizing site of our inaugural discovery to determine if they were still there, and further explore this region to identify additional sites of biodiversity worthy of protection.
Join us on this journey as we embark on a decades long interdisciplinary voyage of discovery that led to finding a second octopus nursery, a skate nursery, and many more exotic creatures that illustrate the adaptability and resilience of deep-sea life. Hopefully, you will leave with a better appreciation of these fragile environments, and acknowledge our responsibility to protect them…
Rachel's journey in earth science began with a profound curiosity about the inner workings of our planet. Her career has carved a unique niche, delving into the fascinating intersection of the seafloor and Earth's mysteries—an area we know less about than the surface of Mars.
Her research is a testament to her curiosity, particularly focusing on the dynamic relationship between life and the ocean/earth interface. Rachel's work primarily centers on terrestrial and submarine hydrogeology, where she diligently unravels the planet's mysteries beneath the ocean's depths. Her ground-breaking research in submarine hydrogeology, specifically the movement of fluids beneath the oceanic crust, has led her to explore the ocean's depths aboard Alvin, a deep-water submersible, reaching depths of 4.5 kilometers. This unique perspective has granted her profound insights into the intricate connections between geoscience and biology in the Deep Ocean. Most recently, she played a pivotal role in an international collaboration, working alongside biologists, policy researchers, artists, and others, focused on understanding fluid exchange and it’s support of life at depths of 3.5 kilometers.
Beyond her research, Rachel is an inspiring educator. She doesn't simply teach; she mentors and guides, passionately committed to shaping the future of her students. Her unwavering dedication to preparing undergraduates and graduates for global challenges is evident in her creation of innovative courses, her mentorship beyond the classroom, and her active involvement in curriculum development. Her mission is to ensure that students not only secure jobs after graduation but also embark on fulfilling careers that continue to evolve. She actively participates in various department, faculty, and university committees, recognizing that collaboration and shared responsibility are essential for a thriving academic community.
Rachel is a scientist who relentlessly pursues knowledge, endeavours to make the world safer, and is devoted to inspiring and supporting the next generation of scientists.
