Anela Choy - The Food Web(s) of the Deep Sea, Earth’s Largest Habitat
The vast water column habitat stretching miles between the ocean’s surface and the seafloor dwarfs all other living spaces on the planet. Research in our new lab at SIO centers on the structure and function of open ocean and deep-pelagic food webs, examining the impacts of climate change, fishing pressure, and large-scale pollution on these ecosystems. Sampling at scales that span the full water column -- and the diversity of inhabitants living there -- requires innovative technology (remotely operated vehicles, camera systems, etc.) alongside targeted laboratory methods. We apply a targeted combination of biochemical tracers (stable isotopes, fatty acids, trace metals) alongside in-situ observations and traditional diet methods. We have also examined the ingestion of plastic in deep-sea species, pinpointing key ecological transport mechanisms that move plastic into sub-surface waters, and through pelagic food webs. This talk provides an introduction to the lab, including new ideas and interests to pursue with colleagues here at SIO.
Mark Merrifield - Preparing for Sea-Level Rise at Imperial Beach
Ocean flooding events occurred frequently at Imperial Beach over the past winter season. The Center for Climate Change Impacts and Adaptation has teamed up with the Imperial Beach community in an effort to assess the wave, tide, and regional water level conditions that lead to flooding events. A network of nearshore sensors has been deployed, and the data collected has been used with predictive models to assess the skill of flood forecasts, and how the risk of flooding is expected to change with sea-level rise. The project demonstrates how to quantify future flood risk at a high spatial resolution throughout the city's coastal zone, and provides a prototype for predictive observing systems at other sites.
*While single-use cups and plates will be available, we are asking everyone to bring their own reuseable items.
The University of California system is committed to going zero waste by 2020, and we’re already diverting 69% of our solid waste from landfills system wide. UC San Diego needs everyone to pitch in with waste reductions efforts. Bring your own plate and cup to the Institutional Seminar instead of using single-use items. #MyLastTrash
