Instruments

Global Positioning System Receiver

Supplied Name: GPS

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.

Improved Meteorological Recorder

Supplied Name: IMET

Supplied Description:

Instrument Type

Generic Name: Improved Meteorological Recorder

Acronym: IMET

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

Generic Description:

An IMET Recorder is an instrument package that can be mounted on a ship or buoy to record mean weather data including air and sea-surface temperature, incoming short and long-wave radiation, precipitation, humidity, wind velocity and barometric pressure. Each sensor in the system communicates digitally and returns calibrated values to a central data recorder.

MicroTSG Thermosalinograph

Supplied Name: MicroTSG

Supplied Description:

SBE-45

Instrument Type

Generic Name: MicroTSG Thermosalinograph

Acronym: MicroTSG

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/133/

Generic Description:

An externally powered, high-accuracy instrument, designed for shipboard determination of sea surface (pumped-water) conductivity and temperature. Salinity and sound velocity can also be computed.

Sea-Bird SBE 48 Hull Temperature Sensor

Supplied Name: SBE48

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE 48 Hull Temperature Sensor

Acronym: SBE 48

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

The SBE 48 is a high-accuracy temperature recorder with non-volatile memory, designed for shipboard determination of sea surface temperature. Installed with magnets just below the water line, the SBE 48's temperature sensor is in contact with the inside of the ship's hull. For more information, see the SBE48 Manual.

Weather Transmitter

Supplied Name: WXT520

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)
