Development of Predictive Models to Relate Population Abundance of Rockfishes and Habitats

A project to develop statistical models that predict densities of demersal fish species and assemblages and to couple these models with the broad-scale seafloor habitat maps in a geographical-information-systems (GIS) environment to spatially predict fish densities on a regional basis.

Underwater Technologies to Survey West Coast Groundfishes

The Habitat Ecology Team recently completed a survey using the Dual Deepworker submersible, part of a "calibration study" to understand the capabilities of various technologies and methods to assess West Coast groundfishes.

Deep sea coral communities and fisheries habitats off California

The Habitat Ecology Team has initiated a research program to assess deep-sea coral communities associated with fisheries habitats off California.

NMFS Habitat Assessment Improvement Plan

Habitat Ecology Team member Mary Yoklavich led a group of NMFS scientists in development of the first nationally coordinated plan to focus on marine fisheries habitat science.

Predicting distribution of benthic macro-invertebrates

As part of the California Seafloor Mapping Program (CSMP), the Habitat Ecology Team has been collaborating with the United States Geological Survey (USGS) and others to create a suite of maps of seafloor morphology, geology, and potential benthic habitats derived from high-resolution multibeam sonar data collected within state waters (shoreline to 3 nautical miles offshore).

Monitoring marine protected areas off central California

The Habitat Ecology Team is collecting baseline data on demersal communities in deep portions of eight new marine protected areas and reference sites in California state waters.

Derelict fishing gear and other marine debris in deep seafloor habitats off California

The Habitat Ecology Team conducted the first quantitative study of man-made debris on the deep seafloor (20-365 meters) off central and southern California. Debris was observed and recorded during visual surveys of fishes and habitats using the manned submersible Delta and accompanying video cameras. We reviewed debris items from the archived videotapes for the period 1993-2007, and quantified information on sources, materials, and impacts of the debris.

Subtidal recruitment of juvenile rockfishes and associated ocean conditions

With decreasing population size of many rockfish species, accurate forecasting of the biomass that recruits to a fishery is needed to adequately manage stocks and set catch quotas.
