Description

SCANFISH CTD Data Endeavor Cruises 321 and 325

PI Notes:
The Scanfish is a towed undulating vehicle carrying a CTD and several other sensors and was utilized on Endeavor Cruises 321 and 325 to Georges Bank. The scanfish is towed along various transacts to map the hydrographic properties of a survey area. During each cruise a number of tows were carried out, and the data are organized by tow. The SeaBird 911plus CTD records data at 24 Hz. It has been processed following the procedures outlined by O'Malley, et al (1998) and subsequently averaged to 1 Hz.

Instruments

CTD Sea-Bird

Supplied Name: SeabirdCTD

Supplied Description:

The SeaBird 911plus CTD records data at 24 Hz.

Instrument Type

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

Scanfish

Supplied Description:

The Scanfish is a towed undulating vehicle carrying a CTD and several other sensors and was utilized on Endeavor Cruises 321 and 325 to Georges Bank.

Instrument Type

Generic Name: Scanfish

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/131/

Generic Description:

The Scanfish is a remotely operated, towed, undulating vehicle system designed for collecting 3D profile data of the water column. It includes a Conductivity, Temperature, Depth (CTD) profiler as part of the instrument package. The Scanfish housing has fins to allow it to dive and rise, an altimeter to determine the depth of the unit, a pump that moves water through the system and a data cable that reports data back to the ship as the fish is being towed through the water behind the vessel. The Scanfish can be configured with additional sensors, e.g. fluorometer.
