Clivar/CO2 Repeat Hydrography Shipboard ADCP data

The US Global Ocean Carbon and Repeat Hydrography program includes routine shipboard ADCP measurements, presented here. Several ships are used for these cruises, so the instrumentation varies among the cruises. All data shown here were collected with profilers made by Teledyne RD Instruments. , some with their original 150-kHz "narrowband" instrument (nb150), and others with 150-kHz and/or 75-kHz Ocean Surveyors (os150 and os75, respectively). The Ocean Surveyors can be operated simultaneously with two types of pings: uncoded pings ("narrowband" or NB), and coded pings ("broadband" or BB). The former provides better range but less vertical resolution than the latter. When both types of pings were used, they are processed independently and presented here as separate data sets. In addition to the velocity measurements, transducer temperature measurements are shown. These should be regarded as providing only very approximate and qualitative information; because of the thermal mass of the transducers, and their position inside a well in the hull, their temperature can differ substantially from that of the ambient seawater.

Acquisition and processing of these shipboard ADCP measurements is funded by the National Science Foundation grants OCE-0223505 and OCE-0752970.

For each cruise we provide a set of links to data plots (left column), to the data location in the NODC JASADCP (center, if present), and to netcdf files with the ADCP data and predicted barotropic tides (right column).
