Multibeam bathymetric data and seismic-reflection profiles collected in eastern Long
Island and western Block Island Sounds reveal previously unrecognized glacial features and
modern bedforms. Glacial features include an ice-sculptured bedrock surface, a newly identified
recessional moraine, exposed glaciolacustrine sediments, and remnants of stagnant-ice-contact
deposits. Modern bedforms include fields of transverse sand waves, barchanoid waves, giant scour
depressions, and pockmarks. Bedform asymmetry and scour around obstructions indicate that net
sediment transport is westward across the northern par of the study area near Fishers Island and
eastward across the southern par near Great Gull Island.

Bioaccumulation and trophic transfer of methylmercury in Long Island Sound
Hammerschmidt, Chad R.; Fitzgerald, William F. (2006-02-22)Humans are exposed to methylmercury (MeHg) principally by consumption of marine fish. The coastal zone supports the majority of marine fish production, and may therefore be an important source of MeHg to humans; however, ... -
