This report presents data obtained from cored sediments collected
during numerous cruises in the Northwest Atlantic area. The cores
were obtained by SCUBA, gravity cores and DSRV ALVIN. The sediments
were sampled with 6 centimeter diameter plastic core liners and ranged
in length from 9 to 63 centimeters. Analyses conducted on sediment
material include organic carbon, organic nitrogen, percent sand-silt-clay,
percent calcium carbonate and pore water concentrations of
ammonia, nitrite, nitrate, silicate and phosphate.
