Description

The cruise track data set for cruise OC454-02 was extracted from the daily underway .csv files by BCO-DMO using a custom perl script. The original .csv files generated from the R/V Oceanus shipboard underway data acquisition system were retrieved from the standard post-cruise data distribution.

Instruments

Echo sounder - single-beam

Supplied Description:

Instrument Type

Generic Name: Echo sounder - single-beam

Acronym: Echo Sounder SB

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

Generic Description:

A single-beam echo sounder is an instrument that measures water depth at a single point below the platform by timing pulses of sound reflected on the seafloor. The echo sounder transmits and receives sound, accurately measuring the time it takes to leave the sounder, reach the bottom and return to the sounder. It then converts this information into digital or graphic representations of the bottom depth and relief.
The average echo sounder consists of a transmission and reception unit that sends sound signals through the water, receives and decodes information and converts that information into either a graphic or visual form. Attached to the receiver is a transducer that acts as a microphone and a speaker under the water. Sound waves travel at approximately 1500 m/s through the water dependent on water temperature". more from LMS Technologies

Global Positioning System Receiver

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.
