Title: Humboldt Bay, California Benthic Habitats 2009 Geodatabase
Short Name: ca_hb09-geodatabase_Metadata
Status: Completed
Publication Date: 2015
Abstract:

Humboldt Bay is the largest estuary in California north of San Francisco Bay and represents a significant resource for the

north coast region. Beginning in 2007 the Office for Coastal Management began collaborating with the California SeaGrant program and

other local partners to support an ecosystem-based management (EBM) project for Humboldt Bay. One element of this project was to

develop subtidal habitat goals for the long-term management of the bay and provide a framework for conservation and management across

the land-sea interface. The imagery collection and benthic habitat delineation for Humboldt Bay were essential to the development of

subtidal goals and implementation of EBM for the region. Together, these efforts will provide important and replicable data and an

information framework for ecosystem-based coastal and marine conservation planning and implementation. 12 Bit 4 Band imagery was

collected in June,2009 within 1 hour of either side of a minus one (-1) foot tide with low turbidity,low wind,low sun angle and no cloud cover. The horizontal spatial accuracy of the imagery is within +/- 3 meters CE95 of position on the ground and was captured at a spatial resolution (pixel size) of 0.54m x 0.54m. The imagery was tiled and named according to the existing USGS digital ortho quarter quad boundaries (ex. Arcata_South_NE.tif). A small buffer (~100 m) was produced with each tile to prevent gaps in coverage. Habitat features were interpreted and digitized on screen in an ARCGIS Geodatabase 9.3 resulting in accurate and efficient 3D extraction of the data. Habitats were delineated with a high level of detail with the minimum mapping unit (MMU) being 0.01 hectares(approx.10m x 10m).

Purpose:

The data was developed to support ecosystem based management in the Humboldt Bay region. The focus of the mapping was on shallow water benthic habitats with particular concern for eelgrass meadows.

Notes:

10011

Supplemental Information:

The study area covers Arcata (North) Bay, Entrance Bay, South Bay and the Eel River Delta, Humboldt County, California.

This file geodatabase contains three feature layers corresponding to the CMECS 2012 Geoform, Substrate, and Biotic components. These layers were converted from an earlier version classified according to the System for Classifying Habitats in Estuarine and Marine Environments (SCHEME) using the CMECS Crosswalk Tool. Each feature layer has its own metadata record describing the attributes, and data development methods associated with it.
