Observer data span more than two decades and multiple database development interations. To facilitate status of stocks authors and other users of these records, a data set separate from the OLAP was created which reformats and repackages vetted (debriefed) observer data from NORPAC into a common structure, format, and syntax. The granularity of current production data is compromised, however for the purposes of longitudinal research the data set is internally consistant, and spans the developmental boundaries.

These data arise from a field study of groundfish catch monitoring in Kodiak, AK trawl fisheries. Two monitoring components were included in the study: 1) at-sea sampling methods used by observers to sample species composition of catch and 2) shore-side sampling of delivered catch by observers to validate landings species composition reports. The at-sea portion of the study consisted of a side-by-side comparison (two observers) of a proposed new sampling method and the standard sampling method. Observer data were recorded at-sea on paper and transferred to an Oracle database. The shoreside component of this study consisted of observer species composition sampling in plants for later comparison with landings data. The shore-side data were collected by observers in processing plants, recorded on paper and transferred to an Oracle database. Data collection started in April 2011 and continued through August 2011. Third party landings data (NOAA Fisheries, Alaska Regional Office, Sustainable Fisheries Division) that were used in the analysis are stored in an oracle database. Data for both project components (at-sea and shoreside) were collected during normal fishing activities onboard commercial trawl catcher vessels and during normal processing activities in shore-based processing plants.

One type of electronic monitoring of Alaska groundfish catch has been conducted by Pacific States Marine Fisheries Commission using an electronic monitoring (EM) system to collect catch accounting data using video and sensor data of selected fishing vessels in Alaska. Video recordings of fish catch composition aboard selected vessels are collected are stored on hard drives in an effort to track vessel catch and discards to accurately debit discarded catch from the individual fishing quota (IFQ) account of each account holder. This information is collected in place of the sampling for species composition of the catch conducted by human at-sea catch monitors or observers. Reviewers of the videos enter data from the drives and maintain data integrity and quality. Raw, reviewed electronic monitoring data collected by Pacific States Marine Fisheries Commission must have additional data items added to it to conform to the standard format of data normally collected by Alaska observers in order for the data to be processed by catch accounting of the NMFS Alaska Regional Office. The EM_OBSINT tables contain these transformed data. These data, like data collected by Alaska groundfish observers, and transmitted electronically to the AFSC and are the source data for those interfaces used for fishery management, scientific inquiry and fishing activity monitoring by industry.

Fishery regulators and industry require near real time fishery statistics formatted appropriately for their software to record and process. This project is the result of the extract, transform, and load processes that provide that utility to these users.

Data collected by the ATLAS Client and transmitted electronically or by fax to the AFSC are loaded into production transaction tables which are the source data for those interfaces used for fishery management, scientific inquiry and fishing activity monitoring by industry.

The core function of the Resource Assessment and Conservation Engineering (RACE) Division is to conduct quantitative fishery surveys and related ecological and oceanographic research to measure and describe the distribution and abundance of commercially important fish and crab stocks in the eastern Bering Sea, Aleutian Islands, and Gulf of Alaska. This includes measuring the abundance of fish (including rockfishes) in rocky untrawlable areas. To accomplish this, we are mapping untrawlable areas using an ME70 multibeam data. These data area stored as image files ArcGIS shapefiles

The scientific objective of the Gulf of Alaska Survey (GOA Survey) is to assess Young of the Year (YOY) groundfish, salmon, plankton, and oceanographic conditions across the coastal, shelf, slope, and offshore waters of the GOA and to provide information on species distribution, ecosystem structure, and marine productivity in response to changes in season, region, and climate. Specific objectives are to 1) observe epi-pelagic fish communities by sampling with a rope trawl towed at the surface; 2) collect electronic oceanographic data including CTD (Conductivity-temperature-depth) vertical profiles of temperature, salinity, light transmission, chlorophyll a fluorescence, and photosynthetic available radiation (PAR); and 3) collect biological oceanographic samples (zooplankton and water) by oblique bongo tows and water sampling.

The core function of the Resource Assessment and Conservation Engineering (RACE) Division is to conduct quantitative fishery surveys and related ecological and oceanographic research to measure and describe the distribution and abundance of commercially important fish and crab stocks in the eastern Bering Sea, Aleutian Islands, Gulf of Alaska, and, historically, the U.S. West Coast. As part of these efforts, oceanographic data is collected using an instrument attached to the bottom trawl headrope. The data includes: pH, turbidity, depth, temperature, salinity and O2. These data are stored on an AFSC server as .txt files.

In November, 2006, Oceanographic observations were initiated during the resupply cruises to the Little Port Walter Research Station on lower Baranof Island, Southeast Alaska. Six sampling stations were selected starting at mid channel, Stephans Passage near Snettisham Inlet then, near the intersection of Stephans Passage and Fredrick Sound by Brothers Islands, then, near the intersection of Fredrick Sound and Chatham Strait off of Kingsmill Point and then three stations across lower Chatham Strait just north of the latitude of Little Port Walter. An SBE19plus conductivity, temperature and depth recorder was used to take water samples at a speed of approximately one meter per second from the surface to a depth of 250 meters. These observations are intended to be part of the Southeast Alaska Ocean Observing System (SEAOOS). Data are stored as CNV files, HEX files and jpg files on Frank Throwers computer.

The GOA/AI Bottom Trawl Estimate database contains abundance estimates for the Alaska Biennial Bottom Trawl Surveys conducted in the Gulf of Alaska and the Aleutian Islands in alternate years. The estimates build upon raw and summary data available from the RACEBASE database and include calculated catch-per-unit-effort (cpue)s for principal species of groundfish and key invertebrates for each survey region. The cpues are averaged by survey strata, and then average cpues are multiplied by stratum areas which results in estimates of biomass and numerical abundance. Length and age data are combined with abundance to estimate the population at length and sex and population at age and sex.
