* » Abstract |
The Fisheries Research Survey team proposes to conduct the West Coast Groundfish Bottom Trawl Survey from May to October 2019. The goal of the survey is to ensure the sustainability of marine fisheries with a focus on ending overfishing. The groundfish fishery supports management for 90+ commercially fished stocks off Washington, Oregon, and California and is the primary source of fishery-independent data necessary for stock assessments of managed groundfish species inhabiting trawlable habitat along the upper continental slope and shelf. The survey provides data on abundance, spatial distributions, sex, length, maturity, weight, and age structure of groundfish in trawlable habitats. The survey also collects key environmental data (temperature, depth, dissolved oxygen, turbidity, in vivo fluorescence, irradiance, wind speed, location) in association with each tow for use in ecosystem based fisheries management. This data set contains information on date, time, vessel, trawl identification (i.e. unique number), trawl performance, location, depth, area swept, trawl duration, temperature, species, haul weight, average individual weight, sex, length, length method, fish age and age structure. |

The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle. |
Lineage
» Lineage Statement |
Data is captured using at-sea data collection software that records sensor time-series as well as captures fish catch and individual compositions. |
