Title: Most Common Adult Distribution: Bocaccio Rockfish, California, 2001
Contributors:- Polygon data
- 2001
Summary: This polygon shapefile contains the most common distribution for adult Bocaccio Rockfish (Sebastes paucispinis). The process of creating this shapefile included creating contour lines, in 5-meter intervals, from bathymetry lines. Depth ranges were taken from four different references (see Resource Details Supplemental Information). After the depth range between which this species is most common was determined, they were rounded to the closest 5-meter interval. The deepest and shallowest shapefile lines were connected by a line at the northern end and southern end (determined by their geographical range from north to south). This shapefile was then converted to polygon. The goal of this shapefile was to provide a range in which this species could occur, given that their kelp canopy, rocky reef and artificial structures habitat is present. This coverage displays the geographic range of select Pacific Ocean fish species. California Department of Fish and Game. (2006). Most Common Adult Distribution: Bocaccio Rockfish, California, 2001.

Title: Kelp Canopy: California, 1999
Contributors:- Polygon data
- 2000
Summary: This polygon shapefile depicts kelp beds along the California coast, which are a critical habitat for many important sport and commercial species of invertebrates and fishes. Kelp is also harvested by commercial and sport concerns. Until now, kelp bed area figures used in harvest regulatory processes by the State of California have been based upon hardcopy maps created from 1989 aerial photography, displaying hand drawn delineated features of the kelp canopy. The Fall 1999 project digitally remeasured the 1989 kelp maps and established new digital methods to calculate the area of the 1999 kelp canopy based on aerial, color-infrared photographs. The objective was to create a baseline that could be used to assess the effects of current and future use of coastal kelp. File reindexed to match California Department of Fish and Wildlife administrative kelp bed boundaries modified by changes to California Code of Regulations, Title 14, Section 165, effective April 1, 2014. The State of California Fish and Game Commission established and mapped kelp bed boundaries for the purpose of administering kelp harvest leases and harvest regulations (Title 14, California Code of Regulations, Section 165.5). The purpose of this coverage is to provide an easy-to-use, state-wide GIS shapefile for graphic presentation. This dataset was not intended for use in determining linear or areal dimensions of kelp distribution or for areal comparison with other kelp datasets. California Department of Fish and Wildlife Marine Resources Region. (2000). Kelp Canopy: California, 1999. California Department of Fish and Wildlife. Marine Resources Region. Available at: http://purl.stanford.edu/wn780ng0200. This data was revised on 09-29-09. The revisions resulted in the removal of polygon overlap which increased overall kelp area 0.71 sq. mi. The overlap involved the following administrative beds: 218 (0.000229 sq. mi.), bed 305 (0.714568 sq. mi.), and bed 306 (0.000088 sq. mi.). In addition, the data was intersected with the administrative kelp beds. 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, storms and harvest levels preceding the dates of survey photography, tidal changes, and water clarity. 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. Most of the coastline, however, has been surveyed only on five occasions (1967, 1989, 1999, 2002, 2003). 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 photo index for each year to determine whether photographs were acquired for an area of interest. This shapefile is the product of a multi-step process of converting aerial photographs in various formats to digital .jpg files by scanning them. The scanned images were then georeferenced and classified using an unsupervised classification algorithm. Classified images (water, low density/submerged kelp, medium density kelp, high density kelp) were converted to ArcInfo Grids, and then to an ESRI shapefile. Linear or areal extent of kelp was and should be derived from the original classified images ONLY. These are public data. The Department of Fish and Wildlife must be credited with the collection, analysis and distribution of these data. This layer is presented in the WGS84 coordinate system for web display purposes.

Title: Kelp Canopy: Southern California, 2011
Contributors:- Polygon data
- 2012
Summary: This polygon shapefile depicts the 2011 aerial kelp survey that was created from Digital Multi-Spectral Camera image files. The data was collected and processed by Ocean Imaging under contract by the Naval Air Systems Command (NAVAIR). This mosaicked multi-spectral imagery targeted giant kelp beds along the Naval Air Systems Command (NAVAIR) Point Mugu Sea Range. The area from Santa Monica Pier, Los Angeles county to Pt. Magu, Ventura county were not photographed. Some of the outer portions of kelp beds were cut off due to inadequate overlap in aerial surveys and these areas are noted in Grid Code 2. The imagery was collected on November 22 and December 07-08, 2011 from altitudes between 10,000 to 12,500 feet. 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 any omissions. The data are projected in California Teale Albers using North American Datum 1983. File reindexed to match CDFW kelp administrative kelp bed boundaries modified by changes to California Code of Regulations, Title 14, Section 165, effective April 1, 2014. The dataset is used to assess the extent of kelp resources along the Southern California coast (Point Loma to two miles north of Gaviota Beach). The dataset was collected and created with the same camera system and processing software as the 2008 survey. Surface and subsurface kelp canopy imagery was collected under the same classification scheme. The user is cautioned to look for areas which appear truncated. 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, 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 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 no kelp data are present may 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.

Title: California Coastal Estuaries
Contributors:- Polygon data
- 2014
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.

Title: California Coastal Eelgrass Habitats, 2010
Contributors:- Polygon data
- 2014
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.

Title: Predicted Nearshore Benthic Substrates with Depth: Northern California Coast, 2012
Contributors:- Polygon data
- 2012
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.

Title: Major Storm Water Discharge: Southern California, 2009
Contributors:- Polygon data
- 2009
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.

Title: Power Plant Entrainment (Polygons): Southern California, 2008
Contributors:- Polygon data
- 2009
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. The reference used to create this shapefile: Foster, M., Steinbeck, J. 2008. Compilation of California coastal power plant entrainment and impingement estimates for California State Water Resources Control Board staff draft issue paper on once-through cooling. California State Water Resources Control Board. This coverage displays the estimated extent of area affected by power plant entrainment in the Southern California Bight, the curved coastline of Southern California between Point Conception and San Diego. Entrainment is a process by which small aquatic organisms are carried by the cooling water into a power plant and assumed killed by heat, turbulence and/or chemicals.

Title: Kelp Canopy: California, 2008
Contributors:- Polygon data
- 2009
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.
