The Expendable Bathythermograph (XBT) has been used by oceanographers for many years to obtain information on the temperature structure of the ocean to depths of up to 1500 meters. The XBT probe is typically launched ...

Profiling floats are neutrally buoyant devices that periodically surface to transmit data to a satellite system. The float drifts along a specified pressure surface for some period of time (typically seven to 10 days) ...

This document is intended as a general guidance for creating and maintaining data collections in ICES – although a number of the general principles can be applied anywhere. It will particularly be a useful resource for ...

Drifting buoys (UNESCO, 1988) have a long history of use in oceanography, starting in late 1978 with the First GARP Global Experiment (FGGE), principally for the mea surement of currents by following the motions of ...

Current meters are primarily used for measuring water velocity through time. Moored instruments may use mechanical (rotor and vane), electromagmetic, o r acoustic technology to perform the measurements. Current ...

ADCPs (acoustic doppler current profiler) were first introduced to the oceanography community in the late 1970s (Rowe and Young, 1979). The instrument measure s water velocity over a range of depths using doppler ...
