Title: Astoria Commercial Dungeness Crab Greatest Importance Percent Volume Polygons, Ecotrust, 2012
Geospatial Data Presentation Form: vector digital data

Description:

Abstract:
These data are a percent volume contour polygons derived from the aggregation of fishing ground layers. This included commercial Dungeness Crab fishing. A percent volume contour (i.e. Isopleth) represents the boundary of the area that contains x% of the volume of a probability density distribution. In this case the probability density distribution is the stated importance of the fishing grounds. The overall Stated Importance values were then narrowed to the top 10% & 20%. These data were developed as part of the Marine Fisheries Uses and Values Project - winter of 2009 through the summer of 2010. This project was part of the Oregon Territorial Sea Plan Amendment Process
Purpose:
This map represents the Dungeness Crab fishing grounds for the ports in Oregon that submitted maps for the Territorial Sea Plan amendment process. The ports included in this analysis are: Astoria. The Area of Greatest Importance to Dungeness Crab Fisheries represents the top 10% contour, while the Area of Great Importance to Dungeness Crab Fisheries represents the top 20% contour. The contours are a combination of the social value of the crab fishery grounds, weighted for their economic value, for each port.

Attribute Accuracy:

Attribute Accuracy Report:
Data was derived from interviews with fishermen and each fisherman gave boundaries to their fishing grounds and the value attributed to those grounds. Not all fishermen have the same method for describing their fishing areas, so there is variablity in the results. Some fishermen would give several very detailed areas and other fishermen would give one large, but less detailed area.
Completeness Report: This data is complete.
Positional Accuracy:

Horizontal Positional Accuracy:

Horizontal Positional Accuracy Report: All data is overlayed on NOAA nautical charts, with all layers sharing the same projection.

Process Step:

Process Description:
The data were max normalized using the following equation x = (x - min) / (max - min). The normaliztion put all the datasets on the same scale so that they could be combined without losing valuable areas from samller or lesser valued fisheries. When aggregated together the areas of importance for each fishery are revealed and overlapping areas of importance across fisheries are shown as areas of high importance. The commercial sector analyzed was Dungeness Crab.
Process Step:

Process Description: Single fishery datasets were created for each of the fishing sectors. The sectors included were commercial, charter, and recreation (or sport).

Process Step:

Process Description: Data are combined through an aggregation process where the landings data are distributed to each shaped based on penny allocations and then combined into one dataset for a fishery.

Process Step:

Process Description: Edit data to specific area that fisherman described, using north and south boundaries, depth ranges, or other geographic details.
Process Date: 20090324

Process Step:

Process Description: Ecotrust staff interviews fisherman, collecting data on fishing grounds, fishing history, and value of fishing grounds.
Process Date: 20090324

Process Step:

Process Description: Quality control to check that penny value equals 100 for each fishery that the fisherman participates in and that the fishery shapes are correct.
Process Date: 20090324

Process Step:

Process Description: Using Hawth's tools in ArcGIS 9.3, the percent volume contours were produced
