This bathymetry contour data is in ESRI shapefile format and was derived from a National Oceanic Atmospheric Administration (NOAA), National Geophysical Data Center (NGDC) ETOPO2 data set. An ESRI ArcView extension, Spatial Analyst, was used to create 500m intervals from a database of grid files (2-minute latitude - longitude resolution).
