Title: Diel dynamics of microbial biogeochemistry in coastal marine systems
Abstract: Coastal marine environments maintain their own unique planktonic microbiomes and distinct biogeochemical properties compared to the surrounding ocean waters. Benthic…

Please join us on zoom or in person for this week's hybrid Polar Hour with Dr. R. Steven Nerem (CIRES/the University of Colorado). Boulder.
Satellite Measurements of Sea Level Change: What are they telling us about the future?
Abstract: Satellite altimetry (TOPEX/Poseidon, Jason-1, Jason-2, Jason-3, Sentinel-6) and satellite gravity (GRACE and GRACE Follow-On) measurements have provided a wealth of new information on how sea level has been changing over the last few decades. With 30-year and 20-year time…
The WMIS Student Seminar Series is a low-stakes seminar where students have the freedom to talk about whatever interests them (both personally and professionally). You can volunteer to present or nominate someone here.
All students from all disciplines/programs are encouraged to present and all students, postdocs, and staff are welcome to attend.
Talk Abstract:
Near-Inertial Internal Waves (NIWs) play a key role in the ocean circulation energy balance but their dynamics is challenging. Because NIW dynamics requires synoptic sampling at very high vertical resolution this is only a partially resolved topic in oceanography. Here, I present results from a multi-platform, multi-scale and multi-disciplinary campaign led by the NATO Centre for Maritime Research and Experimentation in the Ligurian Sea (Northwestern Mediterranean Sea) from September to November 2017. The…

Please join us on zoom or in person for this week's hybrid Polar Hour with Dr. Karley Campbell (UiT The Arctic University of Norway).
Inhale. Exhale. Studying sea ice as a living & breathing system
Abstract: Global warming is transforming Arctic sea ice, impacting the communities of specialised microorganisms like algae and bacteria that live within it. Sea ice microorganisms are vital members of the marine ecosystem. They generate and recycle organic carbon, and influence the…
Talk Abstact:
Tropical cyclone (TC) intensity is strongly affected by the air-sea heat flux beneath the storm. Therefore, accurate predictions of upper ocean responses (such as mixed layer deepening, upwelling, and sea surface temperature cooling) under TCs are necessary for improving TC intensity forecast. The accurate wind stress which driven upper ocean current needs to be understood more. In this study the wind stress (or the drag coefficient) into the ocean and the sea state dependence of drag coefficient (Cd) under tropical cyclones is investigated. The…
Please join us on zoom or in person for this week's hybrid Polar Hour with Dr. Jacob Buffo (Dartmouth College).
Talk Title: It’s a Hard Knock Life (In Ice): The Challenges Faced by Ice Dwelling Organisms and Implications for Astrobiology
Abstract: There are abundant and thriving ecosystems in many ice-rich environments on Earth (e.g., sea ice, permafrost, glaciers). Moreover, many high priority astrobiology targets (e.g., Europa, Enceladus, Titan, Mars) are likely characterized by ice-ocean or ice-brine systems…
Note: This is a joint seminar hosted with Caltech and UCLA
Talk abstract:
Mesoscale eddies contain the bulk of the ocean’s kinetic energy (KE), but fundamental questions remain on the cross-scale KE transfers linking eddy generation and dissipation. The role of submesoscale flows represents a key point of discussion, with contrasting views of submesoscales as either a source or a sink of mesoscale KE. Here, the first observational assessment of the annual cycle of the KE transfer between mesoscale and…
