Fisheries and Oceans Canada (DFO) has been conducting surface water trawl surveys since 1992 in the coastal waters of British Columbia, Washington, Oregon and Alaska and in the high seas of the Gulf of Alaska. Data collected in shelf and slope waters of Alaska to depths less than 400 meters are part of this larger survey series, but are limited to 1995-2011. These surveys focused on determining the migratory patterns (1992-2002) and on the growth and physiology (2003-2011) of juvenile Pacific Salmon. The surveys had funding support from the Bonneville Power Administration as part of the 1995-2011 Canada-USA Salmon Shelf Survival Study. The intent of that study was to monitor and evaluate the effects of ocean conditions on the distribution, migration, growth, and survival of Pacific salmon during their first ocean year, and estimate the subsequent impacts on abundance of Chinook salmon adults returning to the Columbia River system.

Fisheries and Oceans Canada (DFO) has been conducting surface water trawl surveys since 1992 in the coastal waters of British Columbia, Washington, Oregon and Alaska and in the high seas of the Gulf of Alaska. These surveys initially focused on determining the migratory patterns (1992-2002) and on the growth and physiology (2003-2016) of juvenile Pacific Salmon. Since 2016, these surveys have been broadened to monitor the whole pelagic ecosystem, retaining a focus on juvenile Pacific Salmon. Surveys were conducted in central north coast and inlets of British Columbia from Southern Queen Charlotte Sound to Northern Haida Gwaii, including the west coast of Haida Gwaii and Hecate Strait, from 1995 to 2020. All records are from shelf waters shallower than 400 meters.

Since 2016, these surveys have been broadened to monitor the whole pelagic ecosystem, retaining a focus on juvenile Pacific Salmon. Surveys have been conducted on the continental shelf of north and west Vancouver Island, included associated sounds and inlets since 1992 and are ongoing. These data are for tows conducted in the continental shelf area for depths shallower than 400 meters.

These surveys initially focused on determining the migratory patterns (1992-2002) and on the growth and physiology (2003-2016) of juvenile Pacific Salmon. Data collected in shelf and slope waters at depths less than 400 meters off Washington and Oregon State are part of this larger survey series, but are limited to 1999-2001.

Since 2016, these surveys have been broadened to monitor the whole pelagic ecosystem, retaining a focus on juvenile Pacific Salmon. Data were collected from sites in the inland sea waters of British Columbia and Washington State, USA, that comprise the Strait of Georgia, Strait of Juan de Fuca and Puget Sound since 2001 and are ongoing.

Fisheries and Oceans Canada (DFO) has been conducting surface water trawl surveys since 1992 in the coastal waters of British Columbia, Washington, Oregon and Alaska and in the high seas of the Gulf of Alaska. These surveys initially focused on determining the migratory patterns (1992-2002) and on the growth and physiology (2003-2016) of juvenile Pacific Salmon. Since 2016, the focus has been expanded to include all components of the pelagic ecosystem while retaining a strong focus on juvenile Pacific Salmon. Given the change in research priorities, there are differences between years in location and timing. The survey series are provided based on large marine ecosystems, so data will vary in availability. These survey data contain fishing and catch information along with biological information recorded. Surveys available here have published reports that outline overall operations and any oceanographic data, zooplankton and additional samples collected.

These data describe marine bird and mammal surveys conducted in glacial fjords of coastal Alaska. Data were collected to document the at-sea distribution and abundance of marine birds and mammals in Glacier Bay National Park (2004), Prince William Sound (2010), Icy Bay (2011) and Yakutat Bay (2011). Following standard US Fish and Wildlife protocols for strip surveys.

The Fisheries and Oceans Canada (DFO) ecosystem surveys consist of research vessel survey data collected to monitor the distribution and abundance of fish and invertebrates throughout the Scotian Shelf, Bay of Fundy and Georges Bank. The surveys follow a stratified random sampling design, and include sampling of fish and invertebrates using a bottom otter trawl. These survey data are the primary data source for monitoring trends in species distribution, abundance, and biological condition within the region, and also provide data to the Atlantic Zonal Monitoring Program (AZMP) for monitoring hydrographic variability. Collected data includes total catch in numbers and weights by species. Length frequency data is available for most species, as are the age, sex, maturity and weight information for a subset of the individual animals. Other data such as ageing material, genetic material, and stomach contents are often also collected, but are stored elsewhere. “Spring” cruises occur in January, February, March and April, and focus on Georges Bank (i.e. 5Z).

This dataset contains two tables comprising catch per unit effort (CPUE) data and length measurements from fish surveys conducted in the nearshore Beaufort Sea, Alaska, between 1988 and 2019. Historical data collected by the U.S. Fish and Wildlife Service (USFWS) includes fish catch and fish length data (measured from a subset of the total catch) from two eras, 1988-1991 and 2003-2005, in the eastern Beaufort Sea (Arctic National Wildlife Refuge). Similar data was collected by the U.S. Geological Survey (USGS) from a subset of the historical eastern Beaufort Sea sites and some additional central Beaufort Sea (Simpson Lagoon and Stefansson Sound) sites more recently, 2017-2019. Here we have compiled and standardized datasets from the three eras of fish surveys.
