Arctic High Resolution Vertical Profiles (CTD) and Current Meter &Moorings

The Ocean-Circulation Database comprises a collection of hydrographic
data gathered during various expeditions to the Arctic Sea initiated
by the Alfred-Wegener-Institute. These expeditions were undertaken
with research vessels Polarstern, Meteor, Knorr and others. They
cover an area 65 deg. North to 85 deg. North. The data series start in
1987 and are continued to the present.

Long-term measurements of currents, primarily in the area of the
Wedell Sea, are gathered from current meter moorings. Data series
having Depth, Current-Direction, Current-Speed, Temperature and
Salinity as parameters are collected. High resolution vertical
profiles (CTD) with parameters Depth, Temperature, Conductivity,
Salinity and Oxygen from numerous stations in areas of interest were
obtained during the various cruises.

Basically the following sensors are used for data acquisition:
- ADCP, RDI,Acoustic Doppler Current Profiler
- AV, AANDERAA, Rotor Current Meter
- AVP, AANDERAA, Rotor Current Meter incl Pressure
- AVT, AANDERAA, Rotor Current Meter incl Temperature
- AVTP, AANDERAA, Rotor Current Meter incl Temperature and Pressure
- AVTS, AANDERAA, Rotor Current Meter incl Temperature and Salinity
- AVTSP, AANDERAA, Rotor Current Meter incl Temperature Salinity and Pressure
- ACM-2, NEIL BROWN Acoustic Current Meter
- MARK IIIB, NEIL BROWN CTD Sonde
- ME-OTS-CTD, Meerstechnik-Elektronik CTD Sonde

The data are stored in a relational database at the
Alfred-Wegener-Institute. At the current time of writing the database
contains datasets of about 250 moorings and of about 300 stations.
The database size (including data from the South) is about 700 MB and
is continuing to grow.
Data can be obtained after prior consultation with the AWI.
