Title:
NOSBATC - bathymetric contour data for the Monterey Bay region from Point Ano Nuevo to Point Sur, California based on NOAA/NOS data (UTM)
Abstract:
This dataset contains bathymetric contours for the greater Monterey Bay area between Point Ano Nuevo to the north and Point Sur to the south. Contours are provided at 10-m intervals to a depth of 200 m and 100-m intervals to maximum depth. The data from which the contours were derived were hydrographic survey points published by NOAA NOS in 1998. This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program Monterey Bay National Marine Sanctuary Project (see this and other older Monterey Bay USGS works archived at https://archive.usgs.gov/archive/sites/walrus.wr.usgs.gov/monterey/index.html.

  2. How were the data generated, processed, and modified?
    Date: Nov-1999 (process 1 of 6)
    C.H. Degnan: extracted bathymetry data from NOAA (1998), gridded it in GMT (Wessel and Smith, 1998) with a 2-second grid spacing, and exported the grid values as ASCII xyz coordinates. Data sources produced in this process:
    • nosbatc
    Date: Dec-1999 (process 2 of 6)
    W.C. Lee: converted bathymetry xyz coordinates to ArcInfo point coverage. Created ArcInfo TIN from point coverage; converted TIN to 50-m grid (Arc: TINLATTICE, quintic option).
    Date: Mar-2001 (process 3 of 6)
    F.L. Wong extracted contour coverage NOSBATC from 50-m grid of process date 199912 in 2 parts. Extracted grid with values greater than -300, generated contours at 10-m intervals, and removed contours landward of -10 m and seaward of -200 m. Extracted a second grid with values less than -100, generated contours at 100-m intervals, and removed contours landward of -200 m. Expanded value ranges were used in the extracted grids to produce continuous contours at the target cut-off elevation. Both sets of contours were combined as a new coverage NOSBATC.
    Date: 27-Mar-2001 (process 4 of 6)
    First draft of metadata created by F.L. Wong using a modified version of FGDCMETA.AML on ARC/INFO data set NOSBATC.
