This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.

These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.
Waterproof camera is submerged and connected to GPS receiver at the surface with Red Hen Systems VMS 300 hardware. Georeferenced video and still photos are collected. Visual observations are of variable unknown accuracy.
Highly variable, on the order of 10 meters.
Observation are from one minute intervals. Some gaps in observations are due to technical problems or sediment dispersion covering the camera lens.
Point features present.
