Map 4c North Central Coast Study RegionMajor Oceanographic Features

Blue zones indicate upwelling centers which are localized at capes (Pt Arena, Pigeon Pt) or expand along much of the coast, while blue arrows indicate plumes of upwelled waters moving south and offshore from upwelling centers. Green arrows indicate plumes of San Francisco Bay outflow, moving either south (during upwelling) or north (during weak winds or winter). Strong winter outflow from rivers like the Russian and Gualala is demarcated by brown arrows. Not shown is the retention zone in Drakes Bay and smaller zones in Bodega Bay and Half Moon Bay. These schematic patterns change with the wind, land runoff, seasons and years.

These maps were developed summarizing monthly averages for temperature (1996 - 1999) and chlorophyll (1998 - 2000) in a 9km grid. Maps are representative of upwelling, intermittent upwelling and winter storm periods.

Soft and Hard Bottom Habitats

California Department of Fish and GameMarine Region GIS Lab, Oct 02, 2007

Predicted SubstrateHard BottomSoft BottomUnsurveyed

Bathymetric data provided by Seafloor Mapping Lab (SFML),California State University Monterey Bay (CSUMB) and Fugro Pelagos, Inc. as part of the California North Central Coast Mapping Project. Additional data for Bodega Bay,San Francisco Bay mouth and Farallon Islands provided by SFML, CSUMB and/or MossLanding Marine Laboratories. Classification derived using a 3 x 3 cell rugosity analysis. Coarse bathymetry data (blue hillshade on bottom) is 200m resolution data from the California Department of Fish and Game.

In some cases where fine-scale bathymetric surveys have not beenconducted, proxies were used to predict hard or soft substrate. In the northern part of the study region, presence of kelp (based on aerial surveys by CDFG) was used as a proxy for rocky bottom habitat. Estuaries were presumed to be soft-bottom substrate. Around the North Farallon Island, existing coarse-scale data (from Greene et al 2004) were used to approximate rock bottom. Note that additional data for Pt. Reyes and Tomales Bay exist, but have not yet been added to the map.

Marine Life Protection ActThis marine bird colony summary map was prepared by the NOAA National Centers for Coastal and Ocean Science (2007) and incorporates data from researchers from U.S. Fish and Wildlife Service, Point Reyes Bird Observatory Conservation Science, and other institutions (see map citation below). The best available information was used to provide estimated numbers of breeding birds and numbers of species for major colony locations along the north central and central coast of California.

Marine Bird Density




Source: 1 - NOAA http://biogeo.nos.noaa.gov/projects/assess/ca_nms/


Seabird data from multiple sources were compiled and analyzed as part of the NOAA North Central California Biogeographic Assessment (2004; http://www.ccma.nos.noaa.gov/products/biogeography/canms_cd/htm/birds/welcome.htm). This map show combined density (birds/km2) of 76 species of marine birds displayed in five minute latitude by five minute longitude cells. At-sea densities are based on combined data of eight survey programs conducted in 1980-2001.

Marine Bird Diversity




Source: 1 - NOAA http://biogeo.nos.noaa.gov/projects/assess/ca_nms/


Seabird data from multiple sources were compiled and analyzed as part of the NOAA North Central California Biogeographic Assessment (2004;http://www.ccma.nos.noaa.gov/products/biogeography/canms_cd/htm/birds/welcome.htm)Marine bird species diversity was calculated for each five minute latitude by five minute longitude cell using density as the variable in the Shannon [Diversity] Index. All 76 marine bird species that had been recorded in the data set were included. This index measures the degree to which a species assemblage is dominated by a few species. If a cell contains high densities of a few species and low densities of all others, the diversity index will be low. Alternatively, if many species are present at similar densities, the diversity index will be high.

dMap 5 Marine Mammal Haulouts and Rookeries

Source: 1 - California Department of Fish and Game 2007 - developed fromdata collected by Mark Lowry for NOAA in 2002 and ammended by Sarah Allen in 20072 - Personal Observations of Sarah Allen, National Parks Service, 2007

This map depicts pinniped utilization of the coast within the study region. Harbor Seal haulouts are represented by grey circles whose diameters indicate the maximum number of animals observed at these locations. Haulouts used by multiple pinneped species are represented as bar graphs depicting the maxium number of each species observed. The positional precision of these data is low. The data were collected during aerial surveys in 2002 and the positions were marked with GPS from a moving plane. To aid in the representation of these data on this map, the points were agregated into 1 square kilometer cells so positions of haulouts could be off by as much as 1km. Estimated numbers of animals at haulout sites represent the maximum number in any season. Note that breeding season numbers may be lower (eg. while thousands of California Sea Lions haulout on the Farallons Islands, less than 100 breed there. Similarly, while around 1000 northern elephant seals haulout on the Farallons, only about half that many breed there). Information on marine mammal rookery sites (a subset of haulout sites) was provided by Sarah Allen, National Park Service, based on observational data.
