Content Description
	Content Summary: This data set depicts the locations of certain structure-forming invertebrates that were found during NOAA, National Marine Fisheries Service, Alaska Fisheries Science Center's Slope and Triennial trawl surveys. These surveys were designed to sample groundfish populations, not invertebrates. Therefore, the user should keep this caveat in mind when using these data. Sample locations are depicted by the position of the survey vessel at the start of the haul. Strucuture-forming invertebrate species included in the data set were chosen by members of the Ad hoc Groundfish Habitat Technical Review Committee. The invertebrates included fall into one of three categories: anemones, corals, or sponges.
	Content Purpose: These data were developed for Pacific States Marine Fisheries Commission in cooperation with the National Marine Fisheries Service Northwest Region and the Pacific Fishery Management Council in support of an Environmental Impact Statement (EIS) to consider the designation and conservation of Essential Fish Habitat (EFH) for Pacific Coast Groundfish. These data were consolidated and integrated in a GIS format to support spatially explicit groundfish habitat modelling and impacts assessment on a coastwide scale.
	Supplemental Information: Users of these data are encouraged to contact NOAA, National Marine Fisheries Service, Alaska Fisheries Science Center, Race Division for more information about the trawl surveys from which these data are derived.
