CTD Sea-Bird SEACAT

Supplied Name: Sea-Bird Seacat CTD

Supplied Description:

four SeaCats,The VMCMs , VACM, and the SeaCats were set to record every 7.5 minutes, the TPODs every 30 minutes, and the Minilog every 60 minutes.

Instrument Type

Generic Name: CTD Sea-Bird SEACAT

Acronym: CTD SEACAT

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/350/

Generic Description:

The CTD SEACAT recorder is an instrument package manufactured by Sea-Bird Electronics. The first Sea-Bird SEACAT Recorder was the original SBE 16 SEACAT developed in 1987. There are several model numbers including the SBE 16plus (SEACAT C-T Recorder (P optional))and the SBE 19 (SBE 19plus SEACAT Profiler measures conductivity, temperature, and pressure (depth)).

Vector Measuring Current Meter

Supplied Name: Standard Vector Measuring Current Meter

Supplied Description:

The VMCMs , VACM, and the SeaCats were set to record every 7.5 minutes, the TPODs every 30 minutes, and the Minilog every 60 minutes

Instrument Type

Generic Name: Vector Measuring Current Meter

Acronym: VMCM

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/114/

Generic Description:

The Vector Measuring Current Meter (VMCM) is an instrument for obtaining ocean current data. It is often deployed on moorings for long periods of time (years). The VMCM employs biaxial propellers and has undergone extensive tests and calibrations (Weller and Davis 1980). It is a well-characterized mechanical current meter and has been used for benchmarking other current meters (e.g., Dickey et al. 1998a). The two sets of orthogonal cosine response propeller sensors directly measure components of horizontal velocity, and direction is determined with a flux-gate compass (estimated resolution of 1.4 and accuracy of 5) to allow rotation of components into geographical coordinates.
