Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Sampling: Chemistry, Environmental Data: Turbidity, Environmental Data: CTD, Environmental Data: Temperature, Location-Elevation: Navigation

Scientific Purpose/Goals: Collect suspended matter and determine its nature and distribution, and measure hydrographic properties of the water column.


Start Port/Location: Woods Hole, MA

End Port/Location: Newport, RI

Start Date: 1977-04-19

End Date: 1977-05-02

Equipment Used: Temperature and salinity, Niskin water sampler, XBT, Nansen bottles, Montedoro Whitney transmissometer with nephelometer, Plessey CTD, Loran-C, Loran-A

Information to be Derived: Time series data; Suspended sediment concentrations;

Summary of Activity and Data Gathered: Full stations: 72 (including CTD, subsurface and surface salinity sample, temperature, transmissometer cast, and water samples at 3 depths). Suspended matter, nutrients, chlorophyll, Coulter counter organic-carbon, and organic nitrogen samples were taken from collected water samples. Salinity samples: 219; XBT: 89 (taken between full stations).

Notes: Normal operations were curtailed at 0535 April 30 when the pump circulating cooling water in the main engine failed. The alarm indicating engine overheating failed to sound and a smoldering fire began on the painted exhaust manifold. Scientific party working in the lab informed the bridge of smoke coming from the engine room and the engine was turned off. The water pump was repaired at sea but the damage caused by overheating other parts of the engine could not be repaired. The ship was adrift from the time smoke was noticed until Tug WHITEFOOT took us in tow at 0958 May 1. We arrived at dock in Newport, RI at 1305 May 2, 1977. Scientific equipment and personnel returned to Woods Hole by truck. Original Center People field contained: Mike Bothner - Ch. Sci., Randy Fabro, Peter Johnson, Joan Lathrop, Marlene Noble, Carol Parmenter, Nora Thom, John West, Sally Wood.
