Instruments

CTD Neil Brown Mark III

Supplied Name: MkIIICTD

Supplied Description:

An ODF-modified NBIS Mark 3 CTD was mounted on the rosette frame.

Instrument Type

Generic Name: CTD Neil Brown Mark III

Acronym: CTD NBIS MK3

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0002/

Generic Description:

The Neil Brown Instrument Systems Mark III Conductivity, Temperature, Depth (CTD) instrument is an integral unit containing pressure, temperature and conductivity sensors with an optional dissolved oxygen sensor in a pressure-hardened casing. Developed in the 1970s, the Neil Brown CTD unit was able to digitize conductivity, temperature and pressure measurements at sufficient speeds to permit oceanographers to study 10 cm features at winch lowering speeds of 30 meters per minute. The most widely used variant in the 1980s and 1990s was the MK3B. The MK3C fitted with an improved pressure sensor to reduce hysteresis was developed to meet the requirements of the WOCE project. The instrument is no longer in production, but is supported (repair and calibration) by General Oceanics.

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

30-liter PVC Niskin bottles mounted on the rosette frame were used to collect samples for salinity, dissolved oxygen and nutrient analyses.

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Sea Tech Transmissometer

Supplied Name: SeaTech Transmissometer

Supplied Description:

A Seatech transmissometer was mounted on the rosette frame.

Instrument Type

Generic Name: Sea Tech Transmissometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0003/

Generic Description:

The Sea Tech Transmissometer can be deployed in either moored or profiling mode to estimate the concentration of suspended or particulate matter in seawater. The transmissometer measures the beam attenuation coefficient in the red spectral band (660 nm) of the laser lightsource over the instrument's path-length (e.g. 20 or 25 cm). This instrument designation is used when specific make and model are not known. The Sea Tech Transmissometer was manufactured by Sea Tech, Inc. (Corvalis, OR, USA).
