Obsolete - AFSC/RACE/EcoFOCI - Otolith measurements and analyses performed in support of FOCI assessment surveys and ecosystem observations in the Bering, Beaufort, and Chukchi Seas and the Gulf of Alaska. 1995 - Present

공공데이터포털

Otolith data are collected to measure age and growth of larval pollock. They are used to determine whether growth rate, hatch data and/or temperature influence fish size.

Obsolete - AFSC/RACE/EcoFOCI - Trawl catch data collected in support of FOCI assessment surveys and ecosystem observations in the Bering Sea and the Gulf of Alaska 1993 to Present

공공데이터포털

The trawl database contains multiple tables of data. The ‘haul’ table contains the location, date, time and depth of the trawl haul. The ‘catch’ table contains the numbers and weights of the taxa in each haul. The ‘length’ table contains the lengths of selected taxa in each haul. There is data for the eastern Bering Sea for 2008, 2010, 2012, and 2014. There is Gulf of Alaska trawl data from 1993 to 2015.

Obsolete - AFSC/RACE/EcoFOCI - Zooplankton data collected in support of FOCI assessment surveys and ecosystem observations in the Bering, Beaufort, and Chukchi Seas and the Gulf of Alaska, 1987 – Present

공공데이터포털

Zooplankton data are abundance by taxanomic group (to species where possible), stage, size and sex. Zooplankton sorting is performed at The Polish Plankton Sorting Institute in Szcecin, Poland. The zooplankton protocol was changed in 2012 to include a wider range of taxaonomic categories for all study areas and to finer taxanomic resolution where possible. Limited biomass information is available using literature values for micrograms carbon of select copepod species. Various gears with different mesh sizes are used to asses different size classes of zooplankton including 20/60cm paired bongos, Tucker, Multinet, MOCNESS, Methot, CalVET and microzooplankton nets hung on nisken bottles.

Obsolete - AFSC/RACE/EcoFOCI: 2010 BEST and BSIERP Study 1WE10/WE10-08

공공데이터포털

Ecosystem & Fisheries-Oceanography Coordinated Investigations (Eco-FOCI) is an effort by National Oceanic and Atmospheric Administration (NOAA) and associated academic scientists. Eco-FOCI's goal is to understand the effects of abiotic and biotic variability on ecosystems of the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and PMEL/AFSC base. This was the last of a series of cruises in support of research of the Bering Ecosystem Study (BEST) and Bering Sea Integrated Ecosystem Study (BSIERP) co-sponsored by the National Science Foundation and the North Pacific Research Board.

Obsolete - AFSC/RACE/EcoFOCI - Ichthyoplankton data collected in support of FOCI assessment surveys and ecosystem observations in the Bering, Beaufort, and Chukchi Seas and the Gulf of Alaska 1972 to Present

공공데이터포털

The dataset contains records of fish eggs and larvae collected during FOCI assessment surveys. Records include all data pertinent to identify where specimens were collected (lat, lon, date, gear used, max depth of gear, water depth). Specific data on specimens includes scientific name, stage of development, number collected (whole numbers and CPUE), lengths of larvae, and diameters and stages of eggs. In addition, there are comments that explain any irregularities that may have occurred during sample collection; depending on the reason data is being extracted, comments may indicate a sample is not suitable for consideration.

Obsolete - AFSC/RACE/EcoFOCI: 2011 Gulf of Alaska IERP Cruise TN263/1TT11

공공데이터포털

A total of 105 stations were occupied. There were two sample grids (southeast Alaska and Yakutat Bay) and two transects in the vicinity of Kayak Island. At each station we sampled using paired 20 and 60 cm Bongo frames (150 and 500 micron mesh nets, respectively) and a Sameoto neuston sampler (500 micron mesh net) to estimate the abundance of zoo- and ichthyoplankton. A SeaBird SeaCat (SBE 19 plus) was used with the bongo frames to determine the depth of the samplers in real time and to measure temperature and conductivity. At a few selected stations depth-stratified plankton were obtained with a 1 meter squared MOCNESS (500 micron mesh nets) and at other selected stations microzooplankton were sampled with vertical tows of a CalVET net (53 micron mesh).
