Improving understanding of factors affecting the health and populations of ecologically and commercially important fish and other species, and how ecosystems respond to change.
The unparalleled warming, reduced ice spread, and early sea ice retreat occurring in the Arctic has enormous implications for surrounding ecosystems and Arctic biotic interactions. This project aims to improve understanding of factors affecting the health and populations of ecologically and commercially important fish and other species, and how ecosystems respond to change.
The Ecosystem Fisheries Oceanography Coordinated Investigations (EcoFOCI) project collects time series data of temperature, salinity, chlorophyll fluorescence, oxygen, light and currents at nine mooring sites, along with hydrographic surveys and plankton sampling in the Chukchi Sea and the Distributed Biological Observatory (DBO) Regions 1-5. This project involves Arctic cruise expeditions, which examine physical, chemical (nutrients and oxygen) and biological (chlorophyll, ichthyo-, and zooplankton, and benthic fish and invertebrates) distributions in the northern Bering Sea and the Chukchi Sea. In addition to providing annual time series of physical, chemical and biological variables, the mooring data collected provide estimates of transport of Pacific water and heat exiting the Chukchi shelf through Barrow Canyon.
