Bathymetry of Magothy Bay, VA 2007-2009

This dataset contains the bathymetry for Magothy Bay, Virginia, a small coastal bay located between Smith Island and the mainland of the Delmarva Peninsula near the mouth of the Chesapeake Bay. Methodology for collection is similar to that described in Gomez(2008) thesis (see network links). Pixels are 10x10 meters and depths below Mean High Water are given in meters. Coordinates are UTM WGS84, Zone 18N. For adjustments to Mean sea level and other datums see the NOAA Benchmark Data Sheets (here is an excerpt for a near by benchmark): Station ID: 8638863                                PUBLICATION DATE:  10/30/2003 Name:       CHESAPEAKE BAY BRIDGE TUNNEL                                   VIRGINIA NOAA Chart: 12254                                  Latitude:         36° 58.0' N USGS Quad:  CAPE HENRY                             Longitude:        76°  6.8' W                             T I D A L   D A T U M S Tidal datums at CHESAPEAKE BAY BRIDGE TUNNEL based on:      LENGTH OF SERIES:      19 YEARS      TIME PERIOD:           January 1983 - December 2001      TIDAL EPOCH:           1983-2001      CONTROL TIDE STATION:    Elevations of tidal datums referred to Mean Lower Low Water (MLLW), in METERS:      HIGHEST OBSERVED WATER LEVEL (02/05/1998)    =  2.006      MEAN HIGHER HIGH WATER (MHHW)                =  0.884      MEAN HIGH WATER (MHW)                        =  0.814      MEAN SEA LEVEL (MSL)                         =  0.431      MEAN TIDE LEVEL (MTL)                        =  0.426      MEAN LOW WATER (MLW)                         =  0.037      MEAN LOWER LOW WATER (MLLW)                  =  0.000      LOWEST  OBSERVED WATER LEVEL (01/11/1978)    = -0.895 In June 2013, positive (+) depth values were replaced with negative (-) elevation values for consistency with other VCR datasets.  No datum adjustments of the tidal datum were performed.
