Title: How oceanographic conditions shape early rockfish survival in the California Current and plans to translate this work to pollock in the Gulf of Alaska
Speaker: Will Fennie, PhD, Research Oceanographer at NOAA Alaska Fisheries Science Center, Seattle, WA
Abstract: Understanding how future ocean conditions will affect populations of marine species is integral to predicting how climate change will impact both ecosystem function and fisheries management. Fish population dynamics are driven by variable survival of the early life stages, which are highly sensitive to environmental conditions. As global warming generates extreme ocean conditions (i.e., marine heatwaves) we can gain insight into how larval fish growth and mortality will change in warmer conditions. The California Current Large Marine Ecosystem experienced anomalous ocean warming from 2014 to 2016, creating novel conditions. We examined the otolith microstructure of juveniles of the economically and ecologically important black rockfish (Sebastes melanops) collected from 2013 to 2019 to quantify the implications of changing ocean conditions on early growth and survival.
Title: Biogeochemical modeling of the Northeast Pacific; past, present, and future resources for fisheries oceanography
Speaker: Al Hermann, PhD, Research Scientist at the University of Washington Cooperative Institute for Climate, Ocean, & Ecosystem Studies at NOAA's Pacific Marine Environmental Laboratory, Seattle, WA
Abstract: The high-latitude Pacific and subarctic are home to highly productive ecosystems, including vast populations of harvested fish. These regions can be challenging to sample directly. Over several decades at the Pacific Marine Environmental Laboratory we have applied numerical models to infer past, present and future states of these regional oceans and their biota. These estimates are provided to fisheries scientists to help identify local biophysical dynamics, and to managers to help develop effective management strategies in the face of short- and long-term environmental changes. We offer a brief history of our modeling activities, the present status of our model products, how we serve these to the public, and our plans for the future.
EcoFOCI 2023 Summer Seminar Series
This seminar is part of NOAA EcoFOCI (Ecosystems & Fisheries-Oceanography Coordinated Investigations)'s bi-annual seminar series that are focused on the ecosystems of the North Pacific Ocean, Bering Sea and the US Arctic to improve understanding of ecosystem dynamics and applications of that understanding to the management of living marine resources. EcoFOCI is a joint research program between the Alaska Fisheries Science Center (NOAA/ NMFS/ AFSC) and the Pacific Marine Environmental Laboratory (NOAA/ OAR/ PMEL).
