Leg M28/2 was mainly aimed at the Deep Basin Experiment (DBE)
of WOCE.

The mooring array ACM03/12 consisting of 7 moorings was recovered
at 31-34 S, near the Rio Grande Rise and the Hunter Channel.
A bathymetric survey of the Hunter Channel hes been taken with
METEOR's multibeam echosounder HYDROSWEEP (Paetzold et al. 1996).

44 usable CTD profiles were taken, (Stations No. 292-345) with
abundant samples drawn from a rosette for calibration of the
CTD's conductivity (salinity) sensor.
For positions see the *.SUM file which accompanies this document. 

Also 89 XBT's, 20 surface drifters and 29 RAFOS floats were launched.

Two sound sources were moored.

                                to reduce noise by propeller cavitation.
