CURRENT AND SEDIMENT TRANSPORT STUDIES ON GEORGES BANK

A collection of time-series oceanographic data was obtained from locations on Georges Bank and adjacent continental shelf between 1975 and 1984. Measurements available include current, temperature, pressure, light transmission (beam attenuation). The time series is not continuous at any specific location.

The Massachusetts Bay Internal Wave Experiment, August 1998: Data Report

This data report presents oceanographic observations made in Massachusetts Bay in August 1998 as part of the Massachusetts Bay Internal Wave Experiment (MBIWE98). MBIWE98 was carried out to characterize large-amplitude internal waves in Massachusetts Bay and to investigate the possible resuspension and transport of bottom sediments caused by these waves. This data report presents a description of the field program, an overview of the data through summary plots and statistics, and the time-series data in ...
