AFSC RACE Groundfish and Shellfish Survey Public Data

❗ This repository is NO LONGER BEING MAINTAINED AND HAS BEEN ARCHIVED. This code and effort has been moved to https://github.com/afsc-gap-products/gapproducts. For New FOSS documentation, see https://afsc-gap-products.github.io/gapproducts/content/foss-intro.html. .

The gapproducts repository supports code used to create tables in the GAPPRODUCTS Oracle schema. These tables include the master production tables, tables shared with AKFIN, and tables publicly shared on FOSS.

This code was previously maintained by:

Emily Markowitz (Emily.Markowitz AT noaa.gov; EmilyMarkowitz-NOAA)
Research Fisheries Biologist
Bering Sea Groundfish Survey Team

Alaska Fisheries Science Center (AFSC) National Oceanic and Atmospheric Administration (NOAA)
Resource Assessment and Conservation Engineering Division (RACE)
Groundfish Assessment Program (GAP) 7600 Sand Point Way, N.E. bldg. 4
Seattle, WA 98115 USA

The code in this repository is regularly being updated and improved. Please refer to releases for finalized products and project milestones. The FOSS dataset is only updated once a year and may be slightly behind the GitHub repository. This metadata is regarding scripts and data last ran and pushed to the AFSC oracle on June 01, 2023.
