Chaetognatha of the Andaman Sea
(CSIR-NISCAIR, 1981)
Chaetognatha of the Andaman Sea were studied during 51 and 52 cruises of R.V Gaveshani (Jan to Feb 1979) The area between southeast of Andaman island and north of Nicobar island had relatively higher density Total population ...
Primary productivity of the Andaman Sea
(CSIR-NISCAIR, 1981)
The average surface and column primary productivity, chl a and particulate organic carbon, estimated at 24 stations during Feb. 1979, were respectively 5.3 mg C/m3/d and 273 mg C/m2 /d; 0.03 mg/m3 and 3.64 mg/m2; and ...
Benthic macrofauna of the Andaman Sea
(CSIR-NISCAIR, 1981)
Macrobenthic fauna in the depth range 11 to 2150m comprised 22 faunal taxa. Of these, the polychaetes were the most dominant group and contributed 76.8%. Distribution of macrofauna was substrate specific with maximum (410m ...
Copepod Swarm in the Campbell Bay (Andaman Sea)
(CSIR-NISCAIR, 1981)
During the 68th cruise of R.V.Gaveshani, an unusual abundance of calanoid copepods of family Pontellidae was observed in the Campbell Bay (lat.6 degrees 30'-6 degrees 59'N and long 93 degrees 56'-94 degrees 15'E) Swarm ...
Microbiological Studies on the Sediments of Andaman Sea
(CSIR-NISCAIR, 1981)
Total bacterial population in the sediments widely fluctuated from 2.1x 10 3 to 3.7 x 10 6. There was no significant correlation between organic carbon values and heterotrophic activity. Ratio of gram positive to gram ...
Bromine and Iodine Content in Sponges and Algae of the Andaman Sea
(CSIR-NISCAIR, 1981)
Br and I contents were determined spectrophotometrically in 12 species of sponges and 16 species of algae(red, brown and green). These elements on dry weight basis varied from 0.025 to 1.29% for Br and from 0.001 to 0.085% ...
Biochemical Composition of Zooplankton from the Andaman Sea
(CSIR-NISCAIR, 1981)
Protein was the dominant constituent in mixed zooplankton major planktonic groups and some common species collected from the Andaman Sea. Overall mean values, calculated as a percentage of dry weight, were 45,14 protein, ...
Food Components of the Andaman Sea
(CSIR-NISCAIR, 1981)
Detrital carbon in the Andaman Sea constitutes about 92% of the total particulate carbon while phytoplankton and zooplankton constitute small fractions of the total suspended matter. Latitudinal relationship between ...
Some Heavy Metals in Fishes from the Andaman Sea
(CSIR-NISCAIR, 1981)
Muscles, liver, gills and heart of several fishes and some zooplankton(whole sample) collected from the Andaman Sea were analysed for Cu, Mn, Zn, Fe, Ni and Co. The concentrations of practically all the metals were highest ...
Dissolved Petroleum Hydrocarbons in the Andaman Sea
(CSIR-NISCAIR, 1981)
Mean dissolved petroleum hydrocarbons, measured using UV-spectrophotometry, at 0 and 10m were 51 plus or minus 1 and 55 plus or minus 1.2 mu g/litre respectively; range of variation being between 28 and 83 mu g/litre. Very ...
