AFSC/FMA/North Pacific Observer Debriefed Data Presentation Layer (OBSINT)

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.

All of these data are collected cooperatively from private commercial fishing interests and are protected from general release by confidentiality statutes. This protects the private business interests of industry while still providing NOAA Fisheries with the detailed information necessary to effectively manage the ecosystem. The staff authorized to use these data include NOAA Fisheries' scientists and managers participating in a broad range of activities including:

stock assessments,

marine mammal interactions,

food habits,

fish age analyses,

economic analyses,

fishery management plan development,

in-season fishery management.

The data are also shared with other authorized users in the Alaska Department of Fish and Game (ADF&G) and North Pacific Fishery Management Council staff with similar responsibilities.

Aggregations of observer data which protect confidentiality are periodically developed and released to the public. Observer data serve as essential building blocks for numerous public analyses, reports, and scientific documents.

Norpac (Observer) ata are transformed and loaded into the presentation layer tables as the review of those data sets (cruise, permit) is completed and observer debriefing is finalized

All unagregated observer data is confidental to the vessel and or plant from which the fishery activities were observed. Aggredated data is provided to the public by AKFIN and PACFIN.

Access to confidential data is provided to researchers who have an approved confidentiality agreement on file with FMA divsion.

These data are intended for use by status of stocks authors and other researchers who require a longitudinal view of observer data. Records derived from the production database after 2007 have been modified to afford a presentation layer that spans the entire domestic observer program.

Data resides at the Alaska Fisheries Science Center OFIS division server farm on an Instance of an Oracle relational database.

These data are merged data sets reporting observer data from both prior to the observer redevelopment project and after the new model went live in December of 2007.

Because the granularity of the data changed at the development boundary, these data may have lost some of the richness of the newer data model. Some denormalization of post 2007 data has occurred.

Any bias is inherited from the source observer data.

These data are recomputed whenever the underlying data is changed.

The error and debriefing QA/QC process for source data applies.

N/A

Observer Data are never static and subject to continuous revision.

RAID 5 Architecture, Tape back up and off site storage.

Raw observer data is denormalized and flattened for analytical users.
