This grid represents approximately 37 kilometers of bathymetric data collected in 2005. These data were collected using an interferometric sonar (Systems Engineering and Assessment Ltd. (SEA) 2000 series) by the U.S. Geological Survey during USGS survey 2005-04-FA. These bathymetric data were used to define the morphology of the bay floor in Moultonborough Bay, Lake Winnipesaukee, New Hampshire as part of a collaborative USGS and New Hampshire Department of Environmental Services research program to assess the distribution of variable leaf water-milfoil. The morphology of the bay floor aids in defining the physical characteristics of specific benthic habitat environments within the bay.
