Parameters

BODC CODE	Rank	Units	Title
CNDCPR01	1	Siemens per metre	Electrical conductivity of the water body by in-situ conductivity cell
PRESPR01	1	Decibars	Pressure (spatial coordinate) exerted by the water body by profiling pressure sensor and correction to read zero at sea level
PSALPR01	1	Dimensionless	Practical salinity of the water body by conductivity cell and computation using UNESCO 1983 algorithm
TEMPST01	1	Degrees Celsius	Temperature of the water body by CTD or STD

Definition of Rank
Rank 1 is a one-dimensional parameter Rank 2 is a two-dimensional parameter Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

Narrative Documents

AML Conductivity Temperature Depth profiler CTD-12

A self-contained CTD with platinized 4-electrode glass conductivity cell, pressure-protected thermistor temperature sensor and a semiconductor strain gauge pressure sensor plus integral data logger. The instrument package was superseded by the AML CTD-12 plus.

RV Clupea 18/96 CTD Data Documentation

Documentation for CTD data collected on R.V. Clupea cruise 18/1996 (18 - 30 November 1996) by Fisheries Research Services, Aberdeen.

The temperature and salinity data were collected using a STD12 instrument which was calibrated using bottle samples and thermometer readings to produce the following equations:

T(cal) = T(obs)
C(cal) = 1.024597C(obs) - 0.888818
