|1998 Sedimentation Cruise|
The Lake Tanganyika Biodiversity Project sponsered a
sedimentation research cruise on board the R/V
Tanganyika Explorer (Fig. 1) in January, 1998. This cruise was
directed by the University of Arizona, under contract to LTBP.
The purpose of the cruise was to collect bathymetric data, sediment
cores (Fig. 2), and water samples as part of an investigation of the
long term changes in sedimentation rates resulting from watershed
deforestation and subsequent soil erosion, and the effects
those changes may have had on the ecology of Lake Tanganyika.
The cruise targeted both pristine and heavily impacted catchments.
Cruise operations were divided into 3 legs of varying duration,
working in both Tanzanian and Burundian waters of the lake. It
was a truly international expedition, with participants from all
four riparian nations, Malawi, UK, USA, and France.
Cruise operations, logistics and scientific activities all ran
extremely smoothly on this cruise, thanks to the hard work of the
many team members involved as well as the excellent crew. The
productivity of the cruise can be judged by the fact that our original
coring plan was vastly exceeded successful and timely
completion of the planned coring targets during all legs of the
cruise allowed us to obtain cores from two additional deltas (the
Luiche and Gatorongoro rivers) which were not originally planned for
study (Fig. 3). Also the number of cores obtained significantly exceeded
our expectations. A full cruise report has been completed.
