Principal Investigator(s): Michael Bothner
Information Specialist(s): Peter W. Gill, Frances Lightsom
Data Type(s): Environmental Data: Dissolved Oxygen, Imagery: Photo, Location-Elevation: Navigation, Time Series: Mooring (physical oceanography)
Scientific Purpose/Goals: Exchange moorings near the future outfall site in western Massachusetts Bay and off Scituate. Collect about 28 sediment cores from Massachusetts Bay and Cape Cod Bay. Collect oxygen profiles in sediments.
Start Date: 1998-06-17
Start Port/Location: Coast Guard Base, Boston, MA
End Date: 1998-06-19
End Port/Location: Coast Guard Base, Boston, MA
Equipment Used: Mooring tripod, Oxygen profiling system from Sayles, Camera- deep sea, DGPS, Bottom tripod
Information to be Derived: Time series data; Samples and chemical analysis; Suspended sediment concentrations;
Summary of Activity and Data Gathered: The MARCUS HANNA has dynamic positioning which removed the problems of drift as cores were taken. Raja Ganeshram collected interstitial water from Stations 8 and 7. The slow corer should be modified for use in the very soft sediment of Cape Cod Bay in future studies. The corer sank into the bottom several cm before sufficient sediment strength was encountered to support the instrument. Either snowshoes should be attached to the feet or the legs should be lengthened. Moorings deployed: 4 (#529, 530, 531 and 532, all recovered FA 98044 MARCUS HANNA Sep. 30 - Oct. 1, 1998). Moorings recovered: 4 (#516 and 517 deployed FA 98011 WHITE HEATH Feb. 10, 1998; #518 and 519 deployed FA 98019 CHRISTOPHER ANDREW Mar. 25, 1998).
