Late quaternary fluctuations in carbonate and carbonate ion content in the northern Indian ocean
(2008)The proposed research is aimed to understand the Late Quaternary fluctuations in carbonate and carbonate ion content in the northern Indian Ocean with the following specific objectives: 1) To identify suitable paleocarbonate ... -
Study of the role of microbes as source and sink of Dimethyl Sulphide in Dona Paula bay
(2008)The present work examines the link between the distribution of DMS (P) to abiotic and biotic variables in the adjacent bay, at Dona Paula on a temporal scale both at short diurnal and long annual scales. The objective of ... -
Ecological Studies and Molecular Characterization of Thraustochytrids and Aplanochytrids from Oceanic Water Column
(2009)Thraustochytrids, aplanochytrids and labyrinthulids belong to the Class Labyrinthulomycetes of the Kingdom Straminipila or Chromista, which also includes diatoms, brown algae, oomycetan fungi and a variety of photosynthetic ... -
Numerical modelling of tidal circulation and studies on salinity distribution in Mandovi and Zuari estuaries
(2008)The objectives of the thesis were to determine the characteristics of tidal propagation and salinity distribution in the Mandovi and Zuari estuaries using a hybrid network numerical model. A hybrid network model, consisting ... -
Cascade Wittig reaction-double Claisen and Cope rearrangements: one-pot synthesis of diprenylated coumarins gravelliferone, balsamiferone, and 6,8-diprenylumbelliferone
(Elsevier, 2009)A cascade Wittig reaction-double Claisen and Cope rearrangements has been employed for a one-pot synthesis of diprenylated coumarins gravelliferone, balsamiferone, and 6,8-diprenylumbelliferone from a common precursor ... -
Effects of natural and human-induced hypoxia on coastal benthos
(European Geosciences Union, 2009)Coastal hypoxia (defined here as <1.42 ml L sup(-1); 62.5 mew M; 2 mg L sup(-1), approx. 30% oxygen saturation) develops seasonally in many estuaries, fjords, and along open coasts as a result of natural upwelling or from ... -
Evolving trends in biosciences: Multi-purpose proteins - GFP and GFP-like proteins
(Current Science Association, 2009)The sea is considered as holding a clue to many known and unknown biologically active compounds. A family of protein named Green Fluorescent Proteins (GFP)-like proteins, initially isolated from marine organisms, started ... -
Organic carbon and iron modulate nitrification rates in mangrove swamps of Goa, south west coast of India
(Elsevier, 2009)Nitrification, fuelled by ammonium is the pivotal oxidative pathway to nitrogen cycling. In spite of its ecological significance, the factors regulating nitrification rates in the benthic realm remain poorly understood. ... -
Historical records of coastal eutrophication-induced hypoxia
(European Geosciences Union, 2009)Under certain conditions, sediment cores from coastal settings subject to hypoxia can yield records of environmental changes over time scales ranging from decades to millennia, sometimes with a resolution of as little as ... -
Bottom water oxygenation history in southeastern Arabian Sea during the past 140 ka: Results from redox-sensitive elements
(Elsevier, 2009)The concentrations of multiple redox-sensitive elements such as Re, U, Mo, Cd, V, Sb, and Tl were determined in sediments from the southeastern Arabian Sea (9 degrees 21 minutes N: 71 degrees 59 minutes E) to understand ... -
Natural product antifoulants
(Current Science Association, 2009)Natural Product Antifoulants (NPAs) have been proposed as one of the best replacement options for the most successful antifouling agent, tri-n-butyl tin (TBT), which, due to its ecological incompatibility, is currently ... -
Response of the Arabian Sea to global warming and associated regional climate shift
(Elsevier, 2009)The response of the Arabian Sea to global warming is the disruption in the natural decadal cycle in the sea surface temperature (SST) after 1995, followed by a secular warming. The Arabian Sea is experiencing a regional ... -
Antibacterial Activity of 2- (2',4'- Dibromophenoxy) -4, 6 - dibromophenol from Dysidea granulose
(Molecular Diversity Preservation International, 2009)2 - (2',4'- Dibromophenoxy) - 4, 6 - dibromophenol isolated from the marine sponge Dysidea granulosa (Bergquist) collected off the coast of Lakshadweep islands, Indian Ocean, exhibited potent and broad spectrum in-vitro ... -
Amplified Msf tides at Kochi backwaters on the southwest coast of India
(Current Science Association, 2009)Characteristics of tides at eight stations in Kochi backwaters (KB) located on the southwest coast of India are analysed. The Msf tidal constituents at several locations are found to be considerably larger than those ... -
Physiological responses to hypoxia and anoxia in Balanus amphitrite (Cirripedia: Thoracica)
(Inter Research, 2009)The barnacle Balanus amphitrite Darwin is a dominant intertidal and major fouling organism. As its life cycle includes both sessile and pelagic phases, adaptation is a necessity to tolerate harsh conditions that are faced ... -
Polychaete community structure of Indian west coast shelf, Arabian Sea
(Current Science Association, 2009)Macrobenthic polychaete communities of the western continental shelf of India (Arabian Sea) were investigated between 1998 and 2001 using different taxonomic levels to test whether lower resolution data set can explain ... -
