Mudbanks and fisheries along the Kerala coast-myth and reality
(Current Science Association & Indian Academy of Sciences, 2018)Mudbanks, a unique coastal oceanographic phenomenon occurring along the southwest (SW) coast of India during the SW monsoon season, are synonymous with the fishery of this region. Here we examine the validity of the popular ... -
Stable carbon and nitrogen isotopic composition of PM10 over Indo-Gangetic Plains (IGP), adjoining regions and Indo-Himalayan Range (IHR) during a winter 2014 campaign
(Springer Berlin Heidelberg, 2018)For source identification, a field campaign involving simultaneous sampling of particulate matter (PM10) was conducted at eight sampling sites in the Indian mainland during winter 2014. The sampling sites include Delhi ... -
Environmental Factors Affecting the Distribution of Pseudo-nitzschia in Two Monsoonal Estuaries of Western India and Effects of Salinity on Growth and Domoic Acid Production by P. pungens
(Springer US, 2018)Species of the diatom genus Pseudo-nitzschia, some of which produce the neurotoxin domoic acid (DA), were studied to see how environmental factors affect their distribution in two tropical monsoonal estuaries and how ... -
Phytoplankton response to the contrasting physical regimes in the eastern Arabian Sea during north east monsoon
(Elsevier, 2018)Phytoplankton abundance and composition in two contrasting physical regimes - convective mixing in the northeastern Arabian Sea (NEAS) and Arabian Sea mini warm pool (ASMWP) in the southeastern Arabian Sea (SEAS) - were ... -
Evaluation of radiative fluxes over the north Indian Ocean
(Springer, 2018)Radiative fluxes are a key component of the surface heat budget of the oceans. Yet, observations over oceanic region are sparse due to the complexity of radiation measurements; moreover, certain oceanic regions are ... -
Influence of darkness on pigments of Tetraselmis indica (Chlorodendrophyceae, Chlorophyta)
(Elsevier, 2018)In the photic zone, phytoplankton experience diurnal variation in light intensity. However, prolonged exposure to aphotic condition influences their physiological state. Pigment composition is a useful biomarker to decipher ... -
Formation and evolution of the Chain-Kairali Escarpment and the Vishnu Fracture Zone in the Western Indian Ocean
(Elsevier, 2018)Published models for the plate tectonic evolution of the Western Indian Ocean suggest that the Southern Mascarene Basin opened by oceanic crustal accretion between the continental margins of southwestern India and southeastern ... -
Mapping and analyses of two coralline banks in the western continental margin of India using multibeam echosounder data
(NISCAIR-CSIR, India, 2018)Six and eleven profiles of bathymetric and backscatter data are drawn from the gridded (rasterized) maps of the two banks, the Gaveshani Bank and another, an unnamed bank (at latitude 13 0 43.5' N, longitude 73 0 42' E) ... -
Variability in Protein Expression in Marine-Derived Purpureocillium lilacinum Subjected to Salt and Chromium Stresses
(Springer India, 2018)Abiotic factors can cause substantial limitation of growth of microbes. A combination of salinity stress along with chromium (Cr+6), one of the carcinogen, can pose an immediate threat to any living system. To understand ... -
The Dynamics of the Southwest Monsoon Current in 2016 from High-Resolution In Situ Observations and Models
(Elsevier, 2018)The strong stratification of the Bay of Bengal (BoB) causes rapid variations in sea surface temperature (SST) that influence the development of monsoon rainfall systems. This stratification is driven by the salinity ... -
Marine Macroalgae: Prospective Hitchhikers of Ship Ballast
(ASEAN Committee on Science and Technology (COST), 2018)Invasive alien species, on successful establishment, can displace native species. The threat of invasive species arises in view of their ability to outcompete and destabilize native biodiversity. Invasive species are found ... -
Western Pacific Oceanic Heat Content: A Better Predictor of La Ni�a Than of El Ni�o
(John Wiley & Sons, 2018)The western equatorial Pacific oceanic heat content (warm water volume in the west or WWVw) is the best El Ni�o-Southern Oscillation (ENSO) predictor beyond 1-year lead. Using observations and selected Coupled Model ... -
Experimental strategies to assess the biological ramifications of multiple drivers of global ocean change-A review
(John Wiley & Sons, 2018)Marine life is controlled by multiple physical and chemical drivers and by diverse ecological processes. Many of these oceanic properties are being altered by climate change and other anthropogenic pressures. Hence, ... -
Phytoplankton community structure in relation to environmental factors from the New Mangalore Port waters along the southwest coast of India
(Springer International Publishing, 2018)Seasonal and spatial phytoplankton distribution in relation to environmental factors was investigated in New Mangalore Port, a major port along the west coast of India. A well-mixed water column characterized the non-monsoon ... -
Biofouling Community Structure in a Tropical Estuary of Goa on the West Coast of India
(ASEAN Committee on Science and Technology (COST), 2018)Biofouling community structure was studied in a tropical monsoon-influenced Mandovi estuary in Goa, west coast of India. Monthly, seasonal and yearly observations on biofouling on polyvinyl chloride (PVC) panels immersed ... -
Morphotectonic characteristics, distribution and probable genesis of bathymetric highs off southwest coast of India
(Elsevier, 2018)The western continental margin of India and the adjacent deep ocean basins were formed by break-up and separation among India, Seychelles and Madagascar since the Late Cretaceous. The initial India-Madagascar separation ... -
Identification and functional characterization of antimicrobial peptide from the marine crab Dromia dehaani
(Academic Press, 2018)Many naturally occurring biologically active compounds are derived from marine organisms. Brachyuran crab Dromia dehaani is also known as sponge crab. Hence, this study was undertaken to isolate and characterize the ... -
Changing depositional environment and factors controlling the growth of mudflat in a tropical estuary, west coast of India
(Springer Berlin Heidelberg, 2018)Mudflats and associated mangroves are most important ecosystems of tropical coastal regions. Mangroves play a very important role in maintaining the environmental balance; thus in addition to mangrove reforestation and ... -
Assessment of the environmental health of an ecologically sensitive, semi-enclosed, basin - A water quality modelling approach
(Elsevier, 2018)Semi-enclosed basins are environmentally dynamic and some of the most anthropogenically affected components of the coastal realm. They can reflect various environmental impacts, thus qualifying as natural laboratories to ... -
Simulation experiments to elucidate variable fluorescence as a potential proxy for bulk microalgal viability from natural water, sediments and biofilms: Implication in ships ballast water management
(Elsevier, 2018)The variable fluorescence fluorometry measuring microalgal biomass (initial fluorescence - F0, a chl-a proxy) and photosynthetic efficiency (Fv/Fm) has been suggested as a potential tool in ballast-water assessment. In ...
