Instruments

Global Positioning System Receiver

Supplied Name: GPS

Supplied Description:

Trimble differential GPS

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.

Gyro

Supplied Description:

Instrument Type

Generic Name: Gyro

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0079/

Generic Description:

Compass with a motorized gyroscope that tracks true north (heading).

Sea-Bird SeaCAT Thermosalinograph SBE 21

Supplied Name: SeaBird SBE-21

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SeaCAT Thermosalinograph SBE 21

Acronym: SeaBird SBE-21 Seacat

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0667/

Generic Description:

A platinum-electrode conductivity sensor and a thermistor mounted in a corrosion-resistant plastic and titanium housing designed to be continuously plumbed into a vessel's pumped seawater supply. The instrument may be interfaced to a remote SBE 38 temperature sensor mounted either on the hull or in the seawater inlet. Data are both stored in internal memory and output to a serial port for external logging. Conductivity is measured in the range 0-7 S/m with an accuracy of 0.001 S/m and a resolution of 0.0001 S/m. Housing temperature is measured in the range -5-35C with an accuracy of 0.01 C and a resolution of 0.001 C. Remote temperature is measured in the range -5-35C with an accuracy of 0.001 C and a resolution of 0.0003 C. More information at http://www.seabird.com/products/spec_sheets/21data.htm.

Weather Transmitter

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Weather Transmitter

Acronym: WXT520

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/102/

Generic Description:

The ship-mounted Vaisala Weather Transmitter WXT520 measures: Wind speed and direction; Liquid precipitation: rainfall, duration, intensity; Barometric pressure; Air temperature and Relative humidity. (for more information see http://www.vaisala.com/en/products/multiweathersensors/Pages/WXT520.aspx)
