Sea Floor Mapping Group
The Sea Floor Mapping Group (SFMG) is a core capability at the Woods Hole Coastal & Marine Science Center (WHCMSC) that provides support for coastal, lacustrine and marine geologic research. The staff has a wide-range of expertise and is responsible for geophysical and sampling data acquisition, processing,...
Marine geophysical data collected in a shallow back-barrier estuary, Barnegat Bay, New Jersey
In 2011, the U.S. Geological Survey, in cooperation with the New Jersey Department of Environmental Protection, began a multidisciplinary research project to better understand the water quality in Barnegat Bay, New Jersey. This back-barrier estuary is experiencing degraded water quality, algal blooms, loss of seagrass, and increases in oxygen...

LORAN-C LATITUDE-LONGITUDE CONVERSION AT SEA: PROGRAMMING CONSIDERATIONS.
Comparisons are made of the precision of arc-length routines as computer precision is reduced. Overland propagation delays are discussed and illustrated with observations from offshore New England. Present practice of LORAN-C error budget modeling is then reviewed with the suggestion that additional terms be considered in future modeling. Finally...
