Description of activities and requirements for WOCE current meter array ICM3
recovery cruise.
The cruise has two basic scientific objectives:
1. To recover an array of 60 current meters on three arrays of 20 moorings and
2. To make CTD/rosette stations spanning each array.
The current meters are deployed along 20S between approximately 93E and the
continental slope of Madagascar in three arrays:
Array ICM3E consists of 7 moorings located between 92 48'E and 88 10'E;
Array ICM3C consists of 7 moorings located between 74 44'E and 69 22'E; and
Array ICM3W consists of 6 moorings located between 52 47'E and 49 23'E.
Approximately 40 CTD/rosette stations will be made along each moored array.
Stations will consist of CTD measurements to the bottom and bottle samples for
salinity, nutrients, and dissolved oxygen. All samples will be analyzed aboard
ship.
The mooring work will be directed by members of the Buoy Group at the Oregon
State University. The CTD/rosette work will be directed by representatives of
the ODF at SIO.
A conservative estimate is that approximately 34 days of ship time will be
required to carry out the work Starting at 20S off the east coast of
Madagascar and traveling to Fremantle, Australia. Transit time from Cape Town
to the start of work must be added.
Track segment Distance (n mi)
West end of ICM3W to east end of ICM3E 2520
East end of ICM3E to Perth 1440
Total 3960
Operations Times (hr)
Track underway @ 10 kts 396
Mooring recovery @ 12 hr per mooring 240
39 CTD stations @ 4 hr each 156
Total 792 hrs
33 days
We need the following capabilities:
1) Typical UNOLS outfitting for CTD/rosette work, including CTD winch
and cable, appropriate sheaves, 12 kHz transducer and depth recorder,
laboratory space, etc.;
2) A-frame or crane with davit at stern or sideQneeded to hang a block
for retrieving current meter moorings;
3) Winch and wire (10 km) for full-depth trawling to recover moorings
as/if necessary;
4) Support for 15 member scientific party;
5) Underway ADCP and meteorological measurements may be needed; and
6) The most accurate GPS navigation possible for use in locating and
recovering moorings.
Clearances will be needed from the Malagasy Republic and France (for Reunion).
Dr. Thomas Whitworth III will be chief scientist on this cruise.
Correspondence should be directed to him (email: twhitworth@tamu.edu; phone:
