Coupled OA/biology sampling
Field work coupling measurements of carbon chemistry and distribution of free-living organisms
To estimate the carbon chemistry conditions experienced by free-living organisms, we will conduct coupled biological/carbon chemistry sampling for key zooplankton species and settlement plate experiments. As funding allows, we will also increase the capability of the NWFSC to conduct these types of studies in the future.

Research Themes

Ecosystem approach to improve management of marine resources
The California Current Large Marine Ecosystem, Puget Sound and the Columbia River Basin are home to a wide range of freshwater and marine resources that provide a wealth of ecosystem goods and services. Ensuring the resiliency and productivity of the California Current and Pacific Northwest ecosystems requires an integrated understanding of their structure, function, and vulnerability to increased human population growth in coastal communities and competing uses of coastal waterways and oceans. The NWFSC‘s approach to understanding these large ecosystems integrates studies across ecosystems (terrestrial, freshwater, and marine) and scientific disciplines to inform resource managers responsible for conserving marine resources.

Research Foci

Understand how climate influences ecosystem variability
Effective ecosystem management will require an understanding of how climate variability and climate change will alter riverine, estuarine, and marine habitats and consequently how this will affect ecosystem status, function and recovery. Key research elements include better understanding of historical ecological variability through traditional (i.e., indigenous) sources, exploring the vulnerability of key species and biotic communities to expected habitat changes, including decreasing stream flow, increased flood frequency, increasing stream temperature, sea level rise, ocean acidification, shifts in ocean currents, and changed frequency and extent of deoxygenated zones. A secondary goal is to improve understanding of how ecosystems respond to year-to-year and decadal climate variability. Achieving these research goals will provide NOAA and state and local governments with the knowledge and tools needed to incorporate climate change and variability into management of living marine resources.
