Instruments

Anemometer

Supplied Description:

Instrument Type

Generic Name: Anemometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/101/

Generic Description:

An anemometer is a device for measuring the velocity or the pressure of the wind. It is commonly used to measure wind speed. Aboard research vessels, it is often mounted with other meteorological instruments and sensors.

Barometer

Supplied Description:

Instrument Type

Generic Name: Barometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0281/

Generic Description:

A barometer is an instrument used to measure atmospheric pressure. There are many types of barometers identified by make and model and method of measurement.

CTD - profiler

Supplied Name: Conductivity, Temperature, Depth

Supplied Description:

Instrument Type

Generic Name: CTD - profiler

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

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

Meteorological Station

Supplied Description:

Instrument Type

Generic Name: Meteorological Station

Acronym: MET Station

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

Generic Description:

MET station systems are designed to record meteorological information on board ships or mounted on moorings. These are commonly referred to as EMET (Electronic Meteorological Packages) or IMET (Improved Meteorological Packages) systems. These sensor packages record measurements of sea surface temperature and salinity, air temperature, wind speed and direction, barometric pressure, solar and long-wave radiation, humidity and precipitation.
