  1. Title: International Bathymetric Chart of the Arctic Ocean, 500-Meter Resolution GeoTIFF (Version 3.0)

    Contributors:

    Summary: This layer is a georeferenced image (GeoTIFF) of a digital bathymetric model (DBM) compiled with all multibeam, dense single beam and land data added at 500 x 500 meters resolution. The original (DBM) was compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. Data were compiled from several multibeam cruises in the region dating from 1994 to 2011. The goal of this initiative is to develop a digital data base that contains all available bathymetric data north of 64° North, for use by mapmakers, researchers, institutions, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed.

  2. Title: International Bathymetric Chart of the Arctic Ocean, 30 Arc-Second Resolution GeoTIFF (Version 3.0)

    Contributors:

    Summary: This layer is a georeferenced raster image (GeoTIFF) of a digital bathymetric model (DBM) of the Arctic Ocean compiled with all multibeam, dense single beam, and land data added at a resolution of 30 x 30 arc seconds. This is a reprojected version (WGS84) of the 500 meter resolution data layer. The original (DBM) was compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. Data were compiled from several multibeam cruises in the region dating from 1994 to 2011.

  3. Title: Winter and summer zooplankton community and environmental parameters data of thirteen lakes located in Minnesota and Wisconsin

    Contributors:

    Summary: This data set contains the results of a study on taxonomic and functional differences between winter and summer zooplankton communities in lakes across a trophic gradient. Thirteen lakes ('Sites.csv') were sampled across a large trophic status gradient for zooplankton abundance, taxonomic and functional community composition, and Carbon/Nitrogen (C/N) stable isotopes in relation to environmental parameters. Zooplankton abundance and taxonomic identification were made for all stations ('Zooplankton_abundance.csv'); nutrients and C/N stable isotopes values in file 'Environmental_parameters'; lakes light conditions in summer and winter are presented in file 'Light.csv'; bulk zooplankton C/N stable isotopes are in 'Zooplankton_sia.csv' file.

  17. Title: County Service Area 53 Spheres of Influence: Santa Cruz County, California, 2015

    Contributors:

    Summary: This polygon shapefile depicts the sphere of influence (SOI) boundary for County Service Area 53 in the County of Santa Cruz, California representing the Mosquito and Vector Control District under the purview of the Agricultural Commissioner. This coverage displays the entire County except for the incorporated areas of Capitola, Santa Cruz and Scotts Valley. A Sphere of Influence is defined as a plan for the probable physical boundaries and Services Area of a local government agency as determined by the Local Agency Formation Commission (LAFCO). The Sphere defines the extent the City or Special District will probably expand to within the timespan of its current general plan. (pg 47 A Guide to LAFCO Procedures -- San Diego LAFCO 1995LAFCO was created in 1963 to encourage orderly formation of local government agencies, preserve agricultural land resources and discourage urban sprawl. LAFCO is responsible for coordinating logical and timely changes in local governmental boundaries, conducting special studies that review ways to reorganize, simplify, and streamline governmental structure and preparing a sphere of influence for each city and special district within each county. Because counties often consist of large and diverse geographical areas, providing a consistent and adequate service level across all areas can be difficult. Residents of urban communities may want more services than those residing in rural areas. The County Service Area Law (Government Code §25210.1 et seq.) was created in the 1950’s to provide a means of providing expanded tailored service levels in areas where residents are willing to pay for the extra service. When a County Service Area exists, property owners will pay taxes and fees to the County Service Area instead of the county for the services provided.

These boundaries have been approved by the Local Agency Formation Commission (LAFCO) of Solano County. LAFCO was created in 1963 to encourage orderly formation of local government agencies, preserve agricultural land resources and discourage urban sprawl. LAFCos are responsible for coordinating logical and timely changes in local governmental boundaries, conducting special studies that review ways to reorganize, simplify, and streamline governmental structure and preparing a sphere of influence for each city and special district within each county.

The GIS Unit serves all County departments and external customers and provides data on land, features and people of Santa Cruz County. Santa Cruz County encompasses 4 cities and approximately 265,000 people.

Attribute: CITY-CAP = City of Capitola CITY-SC = City of Santa Cruz CITY-SV = City of Scotts Valley CITY-WAT = City of Watsonville GIS Layer Number = 63/ Boundaries were first converted from Local Area Formation Commission (LAFCO) paper maps to AutoCAD drawings. These were plotted and reviewed by the LAFCO executive officer. These data were compiled from many different sources; therefore, the accuracy of the individual layers varies significantly, and some layers do not align exactly with others. In the urban areas, data are generally accurate within five to ten feet of their true geographic coordinates, but in the rural areas, data may be accurate to only within three hundred feet. With these limitations, the County of Santa Cruz disclaims any responsibility for the accuracy or correctness of this data.

  19. Title: Watershed Drainage Basins: Santa Cruz County, California, 2015

    Contributors:

    Summary: This polygon shapefile depicts watershed drainage basins in the County of Santa Cruz, California, including number codes to identify individual watersheds. This coverage includes these major watersheds: 1) North Coast, 2) San Lorenzo, 3) Soquel/Aptos, and 4) Pajaro. These drainage basins function as watershed drainage or catchment areas. The county watershed coding system is designed with two purposes: 1) to be able to aggregate watersheds and associated geographic information by code number ranges, and 2) to allow flexibility for future designation of additional sub-watersheds. Monitoring stations on streams can also be designated using the same coding system. Attributes are coded to represent the major drainage basin a watershed is located within, as well as its location within that Basin. Attributes include a number (1 through 4) representing the major drainage basin, followed by another number indicating its postion relative to other Watersheds in that Basin. The higher the second number, the farther up the drainage basin. This layer is part of a collection of GIS data created for Santa Cruz County, California.

Available at http://purl.stanford.edu/cp847hc0870. GIS Layer Number = 67/ Watershed boundaries were drawn onto USGS 7.5 minute quadrangle sheets using existing topographic lines. These lines were then digitized using at least two known control points per quad sheet. The digital lines were plotted and reviewed by the Water Quality Program Manager of the County's Environmental Health staff. These were then revised to be consistent with Least Disturbed Watershed boundaries (layer 40) and Water-Supply Watersheds (layer 42) which were deemed to be more accurate. These data were compiled from many different sources; therefore, the accuracy of the individual layers varies significantly, and some layers do not align exactly with others.

    Summary: This polygon shapefile depicts santiation repayment areas in the County of Santa Cruz, California. Within these boundaries, property owners who receive financing assistance from the County for hook up and connection to the County's sanitary sewer system are held to a repayment agreement stipulating repayment terms and conditions as determined by the County and in addition to their regular sewer connection permit fees for their Sanitation District.
