Cruise period2001-12-31 — 2002-02-08
StatusCompleted
Port of departureMontevideo, Uruguay
Port of returnStanley, Falkland Islands (Malvinas)
PurposeResearch
ObjectivesBioscience Cruise around South Georgia. In addition to surveying for krill in the vicinity of Bird Island, attempts will be made to measure how quickly currents are carrying krill and other zooplankton into and out of the region. As well as this krill growth rates will be measured and the amount removed by predators.
