You can view metadata and/or download the records by clicking on links in the table below. A brief description of the experiment also is available. Each record is identified in the table by its depth and the name of the mooring. You may want to look at a map of the array to see where the moorings were. If you download any of the files you should review the note on file format. From here you can also move up one level to the list of WOCE experiments.
First Deployment (May 1995 - April 1996)
2nd Deployment (April 1996 - November 1996)
In addition to the subsurface records listed above, RSMAS has made
available wind data recorded at the Hanish West site. The meteorological
station was in place throughout the experiment, from early June 1995
through mid-November 1996. Here, you can
view metadata and download the
record.

The seasonal cycle of the Red Sea exchange through the Bab el Mandeb
is driven primarily by the seasonal change in winds over the southern
Red Sea and Gulf of Aden. In winter the southeasterly winds act to
reinforce the thermohaline circulation of upper layer inflow and deep
outflow. Conversely, in summer the northwesterly winds act in opposition
to the thermohaline forcing and this may partly explain the reversal to
outflow in the surface layer of the strait in summer. Upwelling in the
western Gulf of Aden during summer is also believed to play a role in
forcing the surface current reversal in the Strait and thermocline layer
intrusion into the Red Sea, by changing the stratification and sea level
in the western gulf and hence affecting the alongstrait pressure gradient.
The relative importance of these two wind-forced effects, one direct and
one indirect, is not yet clear. Seasonal changes in surface buoyancy
forcing may also affect the seasonality of the exchange, but this
possibility has yet to be investigated.
The ICM10 data were obtained during a comprehensive experiment at the
southern end of the Red Sea during 1995-1996
(see map). The experiment, which involved moored current meters, T-S
sensors and tide gauges, revealed the annual cycle of flow through Bab
el Mandeb with a level of detail that had not been available before. The
inflow and outflow transports were well resolved and showed a very repeatable
transition between the winter two-layer regime and summer three-layer
regime over the 17 months of continuous observation. The changing
inflow/outflow conditions were clearly reflected in the salinity
variations in the strait, which documented for the first time the extent
and timing of the summertime intrusion of fresh Gulf of Aden thermocline
water into the Red Sea. The annual mean outflow of Red Sea deep water
through the strait was estimated to be 0.37 Sv, with maximum exchange
reaching 0.7 Sv in February and average summer outflow of about 0.05 Sv.

These files have been compressed with the ZIP compression utility.
After downloading them, you will need to expand them. On a PC,
WinZip or Pkunzip will do the job. Other utilities are available
for the Unix and Macintosh environments. After expansion, you will
have ascii files in OSU's stranger format.
The stranger format begins with several lines of header information
that are meant to be machine-readable. They contain a Fortran format
specification that will be useful in reading the file, a pointer to the
first line of data, and a description of the data. Each line of the
current record itself contains the time of the sample, the values
recorded, and a line count.
Please be aware that end-of-line in these files is a carriage-return
plus line-feed (the PC convention). This means that in a Unix
environment (where a single line-feed serves as end-of-line) you may
want to remove the carriage-returns.
