Data include CTD, oxygen and chlorophyll a measurements carried out in the western Bering Sea in July 1989
Data include nearshore sampling, beach sampling, and physical oceanographic data from moorings in the Washington state Olympic region. In addition to species identification and cell numbers, domoic acid levels, chlorophyll concentration, temperature, salinity and nutrients are determined.

The IPHC has conducted research aboard chartered commercial fishing vessels since 1925. Since 1925, the IPHC has completed approximately 271 separate charters: 99 using trawl gear and 172 using setline gear. Charter duration has varied between 1 week to 4 months consisting of 1 to 9 separate trips per charter. From the regular surveys we obtain data on the sex, size and age composition of the population. We also collect data on other aspects of biology such as spawning condition, prior hook injuries, and bycatch data on other species.

Oceanographic time-series data are available from the Newport (Oregon) Hydrographic Line (44° 40'N) due to efforts by scientists from the Oregon State University (Corvallis, Oregon) and the National Marine Fisheries Service (Newport, Oregon). Frequent sampling of the hydrography and plankton occurred during the 1960s and early 1970s. The Newport Hydrographic line is now regularly sampled with 5 cruises per year along the whole line and biweekly cruises to five of the innermost shelf stations. Climatology of the salinity, temperature and density from 1961-1971 can be seen at http://ltop.oce.orst.edu/~ctd/index.html. Euphausiids and larger zooplankton were sampled at night from 1962-1967, at monthly intervals at stations located 5 miles to 85 miles from shore with a 1 m diameter 570 m mesh net. From 1974 through 1995, a very limited number of CTD measurements and plankton tows were made off the Oregon coast. Beginning 1996, the Newport Line was once again sampled on a regular basis. Hydrographic stations located 1, 3, 5, and 10 miles offshore of Newport, OR, were sampled for zooplankton and ichthyoplankton at biweekly intervals from June 1969 - August 1972. Water depths at these stations are 20 m, 45 m, 60 m, and 80 m. In addition zooplankton were sampled on a biweekly monthly basis during May - September 1973, May and August 1974, July - August 1977, May - August 1978, and May - September 1983. Most of this work was carried out using 20 cm bongo nets fitted with 240 µm mesh nets and towed obliquely throughout the water column. The only hydrographic data available are sea surface temperature and salinity. In addition, the 5-mile station was sampled year-round in 1991 and during summer months of 1990 and 1992, using 0.75 m diameter 333 µm mesh nets towed vertically. Sampling off Newport Oregon (44° 40'N) resumed in May 1996, with sampling at stations 1, 5, 10 and 15 miles from shore at biweekly intervals.

Plankton have been sampled yearly in Auke Bay since the 1970s as an index of environmental conditions for salmon fry. The Auke Bay Monitor station (ABM) is sampled weekly from March or April until fry have left the nearshore habitat in June, then monthly, until October each year. Three replicate samples of the upper water column are collected with a 20-m vertical tow using a 0.5 m diameter, 243 Fm mesh Norpac net. Settled volumes are measured immediately in the laboratory, then samples are preserved for detailed microscopic analysis of species, stage and size composition and enumeration. A long-term database is maintained for interannual comparisons.
10-day mean drifting ice boundary in the western part of the Bering Sea. One of predictors for Plotnikovis statistic method of ice forecasting. Information derived from charts of Russian air observations.
Data for the IPHC ocean bottom properties database were assembled from several sources, including the National Oceanic Data Center, National Marine Fisheries Service, Japanese Meteorological Agency, U.S. Foreign Observer Program, University of Alaska, and IPHC longline surveys. The data were quality controlled through comparison of means and variances in areas of overlap. All data were plotted and depths were checked against an independent bathymetry database (TerrainBase). The database has the following boundary conditions: - Areal coverage: Alaska, British Columbia, and U.S. West Coast (to 30N) shelf and upper slope; - Depth: observations must be within 15 m of the bottom and are restricted to areas with a bottom depth of 1,000 m or less; - Variables: temperature, salinity, dissolved oxygen, nutrients (phosphate, nitrate, nitrite); - Time: as complete a historical record as possible. Most of the data were compiled in the months of May through September.

NMFS Observer data was used to improve target fisheries harvest and reduce bycatch.
This is a database of references to surface-sediment heavy metal concentration data in the Bering and Chukchi Seas. It indexes raw data, reports, statistical reviews, and maps.
POI possesses several historical oceanographic data sets: (1) CTD data of POI cruises (about 25,000 stations on the world ocean), (2) Russian and foreign oceanography data on temperature and salinity (300,000 stations on the North Pacific Ocean, about 10,000 stations on the Bering Sea), (3) Data of instrumented observations over ocean currents (buoy stations about 1,000 stations on the North Pacific Ocean), (4) Other data.
