  1. Title: California Coastal Eelgrass Habitats, 2010

    Contributors:

    Summary: This polygon shapefile depicts eelgrass beds on the central California coast that provide foraging, breeding, or nursery areas for invertebrates, fish and birds. The most common type of seagrass in California is Zostera, or eelgrass, which grows under water in estuaries and in shallow coastal bays of the ecoregion. This flowering plant, not an alga, occurs in dense beds and helps prevent erosion and maintain stability near shore by anchoring sediment with its spreading rhizomes and slowing water flow. This file aggregates data from several sources across multiple years. Features shown here should not be considered a representation of condition for any given year, but represent the maximum extent of eelgrass found across multiple surveys over multiple years. This coverage represents eelgrass distribution on the central California coast. California Department of Fish and Wildlife Marine Resources Region. (2014). California Coastal Eelgrass Habitats, 2010.

  2. Title: California Coastal Estuaries

    Contributors:

    Summary: This polygon shapefile depicts estuaries on the California coast that form at the mouths of rivers and streams where freshwater and saltwater meet, and where the salinity varies seasonally and over longer timeframes when the river mouths get closed by sand spits or other barriers. Lagoons are coastal water bodies that are cut off from the sea and generally have low freshwater inputs. Estuaries also differ in their geomorphic origin (coastal plain estuaries, river mouth estuaries, canyon mouth estuaries and tectonic estuaries). The California Marine Life Protection Act (MLPA) defines estuaries as being seaward of the mean high tide line or the mouth of a coastal river, including any area of intertidal or subtidal terrain, together with its overlying water and associated flora and fauna. These estuaries were defined for the northern study region (Point Arena to Oregon) and for the southern study region (Point Conception to Mexico). Areas were outlined by committees comprised of experts from the MLPA Initiative, the MLPA Science Advisory Team and the California Department of Fish and Wildlife biologists. All other areas are from The Nature Conservancy Ecoregional Assessment data. Most of that content is derived from the National Wetlands Inventory (NWI) published by U.S. Fish and Wildlife.

  3. Title: Pinniped Haul-Out Sites: California, 2013

    Contributors:

    Summary: This point shapefile depicts a compilation of marine mammal haul out features used in three Marine Life Protection Act study regions: north central coast, south coast and north coast. Data have been refined through review by each of the SATs assembled for each region. Data were not aggregated or conditioned for evalution in the central coast. This dataset provides coverage for land habitat that is used as haul out sites for periods of rest, molting and as rookeries for mating and pupping by marine mammals that have front and read flippers, including seals, sea lions and walruses. This coverage has been used to evaluate marine protected areas proposals relative to marine mammal protections by the Science Advisory Teams (SAT) assembled during implementation of the Marine Life Protection Act (MLPA).

  4. Title: Predicted Nearshore Benthic Substrates with Depth: Northern California Coast, 2012

    Contributors:

    Summary: This polygon shapefile depicts the "hard" and "soft" substrate categories, however the limitations of the classification methods should be considered when using these terms. Original gridded data were mosaiced and resampled to 5m cell size. The benthic substrate classifications provided here are not derived through traditional geologic interpretations, but are algorithmically defined using seafloor roughness (rugosity analysis) as a proxy for determining areas likely to consist of rocky reef with significant relief and sandy bottoms with lower relief. This method is used for the practical purposes of broadly generalizing habitats for Marine Protected Area (MPA) planning and expedient delivery of information to the Marine Life Protection Act (MLPA) Initiative process. Note that results derived using the approach above may be confounded by factors, including noise and artifacts from the original mapping data, steep slopes and unusual geomorphic features. One consideration is that some areas where rocky bottom occurs may be underestimated by the "rough" category, including canyon slopes, deep water, and rock that is smooth, plateau-like, and/or lightly draped with sediment. While it is important to recognize the above considerations, this information should be considered in the MLPA Initiative process as the best readily available scientific data. Data shown here were gathered through a comprehensive state waters mapping program managed by the California State Coastal Conservancy, Ocean Protection Council, California Department of Fish and Wildlife and the National Oceanic and Atmospheric Administration National Marine Sanctuary Program. The ultimate goal of this program is the creation of a high-resolution 1:24,000 scale geologic and habitat base map series covering all of California's 14,500 km2 state waters out to the 3-mile limit for planning and evaluation of habitats in the Northern California coast study region.

Converted to California Teale Albers Projection NAD 83 by California Departement of Fish and Game, Marine Region GIS Port codes have been used in California marine fisheries for several decades. Throughout the history of their use, CDFG has employed and enforced different standards for acceptable fish landing location and documentation. Many of these ports are located inland, from a time when vessels could easily travel up rivers and land their catch away from the coast. Some ports are in land-locked counties because fishermen could take and sell the catch in their home cities. While many of these activities are now prohibited, historic data is linked to ports throughout the state. This layer is presented in the WGS84 coordinate system for web display purposes.

  13. Title: Kelp Canopy: California, 2008

    Contributors:

    Summary: This polygon shapefile was collected and created with a different camera system and software than the 2002-2007 surveys. This difference in camera system and processing software allows the collection of both surface and subsurface kelp with separate classification schemes. The shapefile was created from Digital Multi-Spectral Camera image files and was collected and processed by Ocean Imaging under contract by the California Department of Fish and Wildlife (CDFW). The dataset represents the 2008 CDFW Survey. The Northern and Central California Surveys were flown October 06-08, 2008. The Southern California including the Channel Islands imagery was acquired October 20-23, 2008. The photographs were taken from an altitude of 12,500 feet, utilizing CDFW's Partenavia aircraft. Surveys were planned to coincide with periods of minimal change between high and low tides to avoid strong tidal induced currents. This dataset is complete, although the user should note omissions. The data are projected in California Teale Albers using North American Datum 1983. File reindexed to match CDFW administrative kelp bed boundaries modified by changes to California Code of Regulations, Title 14, Section 165, effective April 1, 2014. These data are used to assess the extent of kelp canopy resources along the California coast. California Department of Fish and Wildlife Marine Resources Region. (2009). Kelp Canopy: California, 2008. California Department of Fish and Wildlife. Marine Resources Region. Available at: http://purl.stanford.edu/jx253kn5220. This data was revised on 09-29-09. The revisions resulted in the removal of polygon overlap which increased overall kelp area 0.0008 sq. mi. The overlap involved administrative beds 211 (0.000759 sq. mi.) and 212 (0.000024 sq. mi.). In addition, the data was intersected with the administrative kelp beds. Kelp missed due to inadequate overlap: Santa Cruz Island, bed 112, small section of kelp bed missed approximately 3.77km southwest of Diablo Point; Santa Barbara County, bed 32, section of offshore kelp missed south of Canada Del Cojo; San Luis Obispo County, bed 205, small section of the inshore bed missed by Diablo Canyon and east of Lion Rock; San Luis Obispo County, bed 208, small section of offshore kelp missed 4.25km northwest of Point Estero; San Luis Obispo County, bed 210, small section of offshore kelp missed south of Adobe Creek; Monterey County, bed 216, corner of cove/bay missed from False Sur to Pt. Sur; Santa Cruz County, bed 222, partial cloud cover from Needle Rock to Terrace Point may have hidden offshore kelp; Marin County, bed 301, kelp may have been missed between Double Point; Sonoma County, bed 303, section of kelp bed missed around Fort Ross Cove; Mendocino County, bed 307, section of inshore kelp missed between Slaughterhouse Gulch and Jack Peters Gulch. The user is cautioned to look for areas which appear truncated. DISCLAIMER The user is cautioned against making direct comparisons between the various kelp surveys for the following reasons: 1) Timing of the survey is important, particularly with respect to growing season conditions in the ocean, and storms and harvest levels preceding the dates of survey photography. Seasonal variability may account for differences in surveys, which may not reflect a change in the bed's extent, productivity, or harvest level. 2) Statistical significance in change of area should be evaluated. To do this, a variance parameter is needed, which is obtained by repeated measurements. 3) Survey methods have not been/may not be consistent. Some method of calibration between the methods needs to be performed in order to insure a change of area is not due to survey instrumentation, and not misinterpreted as a biological change. 4) An area where apparently no kelp data are present may truly represent an area devoid of kelp, or may represent an area where kelp was not detected due to poor photo quality, missing photo coverage, or other issues with data collection and processing. Photo coverage is extensive for the state, but the user is advised to consult the supplementary information for each year to determine whether photographs were acquired for an area of interest. These are public data. The Department of Fish and Wildlife must be credited with the collection, analysis and distribution of these data.

  15. Title: Power Plant Entrainment (Polygons): Southern California, 2008

    Contributors:

    Summary: This polygon shapefile depicts the estimated extent of power plant entrainment in the Southern California Bight. Included in the attributes is scale range of larvae entrained per year. The attributes also include the offshore distance and the alongshore distance that is affected by entrainment. The entrainment area calculations are based on several assumptions, including (1) that alongshore extent is 5-times cross-shore extent, (2) bottom depth slopes linearly to about 10m at the outer edge of this entrained volume, and (3) the entrainment area appears on both sides of the intake as currents may run in one direction or the other. Where the intake is in an enclosed bay, this area extends beyond the bay when the bay holds less volume than that pumped in a 10-day period (e.g., Alamitos Bay), or is confined to the bay where the bay is large enough (e.g., San Diego Bay). This is a simplified approach and a more detailed assessment should be developed for any specific site that may interact with nearby marine protected areas.

  16. Title: Major Storm Water Discharge: Southern California, 2009

    Contributors:

    Summary: This polygon shapefile depicts the extent of area affected by the top twenty areas of stormwater discharge in the Southern California Bight. The original point data used to create these polygon features was summarized by Eric Steine (Southern California Coastal Water Research Project) in November 2008. Eric Steine used the following reference: Ackerman, D. and Schiff, K. 2003. Modeling storm water mass emissions to the Southern California Bight. Journal of Environmental Engineering 129 (4): 308-317. This coverage displays the extent of area around the location of the top twenty sites where storm water is discharged into the Southern California Bight, the curved coastline of Southern California between Point Conception and San Diego. California Department of Fish and Wildlife Marine Resources Region. (2009). Major Storm Water Discharge: Southern California, 2009. California Department of Fish and Wildlife. Marine Resources Region. Available at: http://purl.stanford.edu/wm787kc2064. --BEGIN ORIGINAL METADATA - THIS INFORMATION MAY NOT BE CURRENT-- Due to the number of storm water discharge sites in the South Coast Study Region, the Science Advisory Tram recommends the SCRSG focus on the largest stormwater sites by discharge volume per year. Without representing differences in pollutant loading, attention is given to the size of the runoff. These estimates of the relative extent of possible toxic impact is based on a study4 performed by Bay et al. (2003), which found that the toxicity zone in the stormwater plume from Ballona Creek had an alongshore affect of approximately one mile up coast and one mile down coast, with an offshore extent of close to 0.75 miles. Assuming similar loading of stormwaters, similar linear bottom slopes, and that the relative volume of stormwater plumes scales with the annual runoff volume, one can increase or decrease these Ballona-derived lengths by the cubic root of the volume ratio (as volume is related to length cubed). This provides a rough scale of the possible extent of stormwater impact for each of these major stormwater sites. Again, this is a simplified approach and a more detailed assessment should be developed for any specific site that may interact with nearby MPA's Processing Steps: 1. Create point feature class using data summarized by Eric Steine (Southern California Coastal Water Research Project). 2. Buffer the coastline of the south coast study region based on the offshore attribute of the stormwater discharge point. Clip the resulting buffer by half the along shore attribute value on each side of the point feature. 3. Clip the buffers to the shape of the MLPA South Coast Study Region boundary. --END ORIGINAL METADATA-- This layer is presented in the WGS84 coordinate system for web display purposes.

  18. Title: Minor Discharges into Near-Coastal Marine Waters: Southern California, 2008

    Contributors:

    Summary: This point shapefile depicts locations of minor discharges into Southern California's near-coastal marine waters, but does not include discharges into enclosed bays and estuaries. The category 'Minor' used to describe this feature was derived from the Marine Life Protection Act South Coast Study Region Scientific Advisory Team conclusion that any facility that had a design flow rate less than 1 million gallons-per-day (MGD) would get a 'Minor' discharge rating. Small aquaculture facilities, desalination plants, and marine labs that discharge more than 1 MGD were included in the minor category. This coverage displays locations of and information about minor ocean wastewater discharges alongthe Southern California Bight, the curved coastline of Southern California between Point Conception and San Diego. California Department of Fish and Wildlife Marine Resources Region. (2008). Minor Discharges into Near-Coastal Marine Waters: Southern California, 2008. California Department of Fish and Wildlife. Marine Resources Region. Available at: http://purl.stanford.edu/fh182cj0385. Data was collected from a variety of sources, including SWRCB Division of Water Quality NPDES permit files and spreadsheets, the Southern California Coastal Water Research Project's Final Report: Discharges into State Water Quality Protection Areas (2003) and associated GIS data, the San Francisco Estuary Institute/SWRCB Water Quality Monitoring Inventory Website, and limited staff field observations. (http://www.sfei.org/camp/servlet/ListPgms?which=byOrg ). In December 2008 a location for Terminal Island Treatment plant was added to this feature class at the request of Brian Owens (DFG). In February 2009 these points were all designated "Minor" by Brian Owens (DFG). If a reason can be given for this minor designation it will be in the reason_adj column of the attribute table.
