Title: Midwater Whiting Trawl Kernel Density Estimate of Effort, 2011-2019, ODFW

Geospatial Data Presentation Form: remote-sensing image

Description:

Abstract: This layer depicts Pacific Whiting fishing effort expressed as tow hours from 2011 to 2019. The Oregon whiting fishery fishes for whiting using mid water gear over open water habitat from the border with Canada to Northern California between approximately 40 - 210 fathoms. The layer was developed using the kernel density function in Arc Desktop 10.8 with default settings. Fishery logbook data are recorded on standardized data sheets by fishermen during their fishing operations. The logbooks are later turned over to ODFW for data entry and processing. Because the data are recorded by many independent sources, ODFW cannot guarantee the accuracy of all logbook data.This layer was developed for large-scale offshore wind energy development planning off of Oregon, and should be used for that purpose only. Use for offshore wind siting or other purposes would require additional analyses of the data. If the user intends to use the data for purposes other than large-scale offshore wind energy planning, please contact: ODFW Marine Resources Program [Justin Ainsworth]. justin.c.ainsworth@odfw.oregon.gov
