Description

Longitude, latitude, date and time (UTC) and seafloor depth (XYTZ) cruise track data were subsampled from the ship's underway sampling system (daily WHOI Athena 1 minute *.CSV files) using a BCO-DMO perl script. The vessel's underway data acquisition system records the best quality navigation data from the Furuno 1850 GPS receiver. The seafloor depth is from the Knudsen 12 kHz channel system and includes the 4 meter transducer depth correction.

Instruments

Global Positioning System Receiver

Supplied Name: Global Positioning System Receivers

Supplied Description:

Instrument Type

Generic Name: Global Positioning System Receiver

Acronym: GPS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/POS03/

Generic Description:

The Global Positioning System (GPS) is a U.S. space-based radionavigation system that provides reliable positioning, navigation, and timing services to civilian users on a continuous worldwide basis. The U.S. Air Force develops, maintains, and operates the space and control segments of the NAVSTAR GPS transmitter system. Ships use a variety of receivers (e.g. Trimble and Ashtech) to interpret the GPS signal and determine accurate latitude and longitude.

Knudsen 320 BR deepwater echosounder

Supplied Description:

Knudsen 320 B/R daat logger with a hull-mounted Edo 323 B 12 kHz High Frequency (HF) transducer

Instrument Type

Generic Name: Knudsen 320 BR deepwater echosounder

Acronym: Knudsen 320

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/156/

Generic Description:

The Knudsen 320 B/R deepwater echosounder is a digital data logging system used to measure water depth (e.g. depth of the seafloor). The system is configured to work with different frequency transducers. For example, the Edo 323 B is a 12 kHz High Frequency (HF) transducer or it can be configured to work with an array of 3.5 kHz Low Frequency (LF) transducers mounted in the hull of a vessel.
