Cruise Report on Research Activity (2001-2002): Indian Ocean

Abstract

Oceanographic data Oceanographic data was collected by Sea Bird Electric CTD (SBE CTD) model 19-03 (Conductivity, Temperature, Depth Recorder) and XBT (Expendable bathythermograph). There were 26 stations. Nine stations of sea condition observation were carried out in Gulf of Thailand, ten stations in Andaman sea and seven stations in Indian ocean. Working area were between latitude 6°N-6°S and longitude 82°-95°E. Position of observation were shown at Fig.1 and Table 1. Profiles of all oceanographic data were shown in Annex II. Zooplankton samples Zooplankton samples were collected in the Andaman Sea (Table2) by bongo net, which attached the 0.33 and 0.50 mm mesh size plankton nets. There were 10 sampling stations. The bongo net was oblique tow by ship speed 3 knots for 30 minutes. The maximum depth of the haul was 60-100 meter below the surface
