The intriguing relationship between coiling direction and reproductive mode in benthic foraminifera
(The Palaeontological Society of India, 1989)Changes in coiling direction in foraminifera have been used extensively as proxy data for paleoclimates. However, most of the studies centred around planktonic foraminifera, and various causes (including reproductive mode) ... -
Composition and origin of buried ferromanganese nodules from central Indian Ocean
(Geological Society of India, 2006)Five buried ferromanganese nodules were recovered at different depths of 167-169 cm (A), 172 174 cm (B), 228 230 cm (C), 328 330 cm (D) and 418 420 cm (E) in a 5 m sediment core from the siliceous sediment of Central Indian ... -
Research vessels
(New Delhi: Department of Ocean Development, 1988)The role of the research vessels as a tool for marine research and exploration is very important. Technical requirements of a suitable vessel and the laboratories needed on board are discussed. The history and the research ... -
Shipboard and laboratory equipment
(New Delhi: Department of Ocean Development, 1988)The polymetallic nodules occur at an average depth of 4500 m. Adequate equipment and techniques are required for the exploration at such depths. Shipboard and various laboratory equipments for the sampling of polymetallic ... -
Nodules of the Central Indian Ocean Basin
(New Delhi: Dep Ocean Dev, 1988)The Central Indian Ocean Basin (CIOB) extends from 0 degree S to 25 degrees S latitudes and 70 degrees E to 90 degrees E longitudes The major portion of CIOB is an abyssal plain and the plains are believed to be developed ... -
Manpower
(New Delhi: Department of Ocean Development, 1988)The recruitment, training and deployment of manpower for scientific work during an oceanographic expedition is discussed. Fifty scientists and 50 technicians in various disciplines of oceanography were recruited. A training ... -
Techniques and results
(New Delhi: Department of Ocean Development, 1988)An area of about 300,000 sq km in the Central Indian Ocean Basin (CIOB) was demarcated to estimate the abundance, grade and reserves of the nodules This area was further demarcated into two regions of 150,000 sq km each A ... -
History and background of the project
(New Delhi: Department of Ocean Development, 1988)The history of oceanography, the discovery of manganese nodules and the background of the developments in nodule research and mining is given The first nodules were collected in 1981 on board the research vessel R V Gaveshani ... -
Cryopreservation studies on the marine diatom Navicula subinflata Grun
(Seaweed research and Utilization Association, 2000)Very little work has been done on marine unicellular algae regarding cryopreservation. The present work was, therefore, undertaken to study the effect of different cryoprotectants and cryopreservation on the growth of ... -
Relationship of fouling diatom number and chlorophyll-a value from Zuari estuary, Goa (west coast of India)
(Seaweed research and Utilization Association, 2000)The diatom cell biomass is expressed in terms of diatom number and chlorophyll -a value on panel of glass slide. The Chlorophyll value in a water body is indicative of the productivity. The present study was conducted to ... -
Growth of fouling diatoms from the Zuari estuary, Goa (west coast of India) under different salinities in the laboratory
(Seaweed research and Utilization Association, 2000)Diatoms take part in the initial process of fouling i.e. primary film formation. In order to understand the growth of the diatoms under different salinity conditions in the laboratory, this work was undertaken. Fouling ... -
Effect of different temperature regimes on the chlorophyll a concentration in four species of Antarctic macroalgae
(Seaweed research and Utilization Association, 2004)Four species of benthic macroalgae belonging to Rhodophyta namely Palmaria decipiens (Reinsch) Ricker, Phyllophora antarctica A. et. E. S. Gepp, Porphyra endiviifolium (A.et. E. S. Gepp.) Chamberlain and Iridaea cordata ... -
Impact of sewage on the distribution, abundance and community structure of rocky intertidal macroalgae of the Colaba Coast, Mumbai, India
(Seaweed research and Utilization Association, 2003)Three transects T1, T2, T3 in the intertidal area of Colaba were sampled for macroalgal distribution, abundance, species composition, diversity and standing stock estimation during 1997-98. Transect T2 was in the vicinity ... -
Isolation, purification and characterization of xylanase produced by Arthrobacter sp. MTCC 5214 when grown in solid-state fermentation
(Elsevier, 2006)Thermoalkalophilic Arthrobacter sp. produced extracellular xylanase, when wheat bran, rice husk, rice bran and bagassae were used as carbon source under solid-state fermentation (SSF). The xylanase enzyme was isolated by ... -
Change detection studies in coastal zone features of Goa, India by remote sensing
(Indian Academy of Sciences, 2006)Digital remote sensing data of SPOT-1 (Nov. 1990), IRS-1C (Jan. 2001) and IRS-1D (Jan. 2003) have been subject to maximum likelihood classifier (MLC) to carry out change detection studies in the coastal zone of Goa. The ... -
Antiviral property of marine actinomycetes against white spot syndrome virus in penaeid shrimps
(Indian Academy of Sciences, 2006)Aquaculture farms, particularly in Southeast Asia are facing severe crisis due to increasing incidences of White Spot Syndrome Virus (WSSV). Actinomycetes have provided many important bioactive compounds of high prophylactic ... -
Biological indicators in relation to coastal pollution along Karnataka coast, India
(Elsevier, 2006)A comparison has been made of sand, silt, and clay percentage of 118 samples from the Ayeyarwady continental shelf, northern Andaman Sea, measured by the sieve–laser diffraction technique and by classical sieve-pipette ... -
Application of foraminifers in ecotoxicology: Retrospect, perspect and prospect
(Elsevier, 2006)In view of the extensive use of foraminifers for the pollution monitoring especially their unmatched utility in deciphering the temporal variation in the type and concentration of pollutants at a given location, the ... -
