Influence of Rainfall Over Eastern Arabian Sea on Its Salinity
(2019)The west coast of India and the adjoining eastern Arabian Sea (EAS) is one of the high rainfall zones of Indian summer monsoon. The summer monsoon rainfall in this region is about 1,036 km3, which is comparable to the ... -
Bioprospection of marine actinomycetes: recent advances, challenges and future perspectives
(2019)In exploring new sources for economically important products, marine environment draws particular attention because of its remarkable diversity and extreme conditions; it is known to produce metabolic products of great ... -
Molecular characterization and phylogenetics of Indian polychaete fauna: scope for implementation in ecological monitoring
(2019)DNA barcodes are increasingly applied to ascertain the taxonomic identification to improve the speed and accuracy of ecological monitoring programmes. The success of integrating molecular approach in routine surveys ... -
Total mercury and methylmercury in commercial marine species from the Goa coast: Constraints on risk assessment and environmental issues
(2019)Mercury (Hg) is a toxic element which accumulates in fish and other aquatic organisms from various sources and poses potential risk to the consumers. Methylmercury (MeHg), the common organic species of mercury, usually ... -
Picophytoplankton Synechococcus as food for nauplii of Amphibalanus amphitrite and Artemia salina
(2019)The naupliar forms are important intermediaries between microbial and classical food web as they can efficiently graze on autotrophic picophytoplankton and heterotrophic bacteria in diverse aquatic ecosystems. Current ... -
Geochemical characteristics of basalts from Andaman subduction zone: Implications on magma genesis at intraoceanic back-arc spreading centres
(2019)This study reports new petrological and geochemical data for the ocean floor volcanic rocks dredged from the back?arc basin of the Andaman Sea and elucidates their geochemical characteristics and petrogenetic aspects to ... -
Hidden biogeochemical anonymities under Antarctic Fast Ice
(2019)Climate change is negatively affecting the extent of summer sea ice and the global oceanic oxygen concentrations, it is therefore imperative to decipher the life processes under the Antarctic fast ice. The biogeochemical ... -
Proteomic response of marine-derived Staphylococcus cohnii NIOSBK35 to varying Cr (VI) concentrations
(2019)Chromium in its hexavalent state is a water-soluble and toxic element to living organisms present in the environment. However, some organisms are resistant and reduce the toxic forms of Cr(vi) to less toxic or non-toxic ... -
Picophytoplankton variability: Influence of Rossby wave propagation in the southeastern Arabian Sea
(2019)The westward propagating Rossby waves and associated currents transport low salinity nutrient-rich water mass from the Bay of Bengal into the southeastern Arabian Sea (SEAS) during winter monsoon, and ensuing changes in ... -
Productivity controls on the redox variation in the southeastern Arabian Sea sediments during the past 18 kyr
(2019)Redox-sensitive elements (uranium, molybdenum and cadmium) and productivity proxies (total organic carbon, calcium carbonate and phosphorous) were analysed to assess the importance of productivity on redox variation for ... -
Note on the genus Lecanophryella (Ciliophora: Suctorea) with description of a new species from west coast of India
(2019)The article presents a review of the literature on known representatives of the genus Lecanophryella containing general characteristics of the members of this genus, information on morphology and data on distribution. ... -
Suppressed biological production in the coastal waters off Visakhapatnam, India under the impact of the very severe cyclonic storm Hudhud
(2019)Tropical cyclones generally enhance biological production due to the increase in nutrients input due to vertical mixing. In contrast, the very severe cyclonic storm (VSCS) Hudhud decreased primary production due to the ... -
Temperature- and size-associated differences in the skeletal structures and osculum cross-sectional area influence the pumping rate of contractile sponge Cinachyrella cf. cavernosa
(2019)Sponges alter the proportion of structural and morphological components such as spicule skeleton and number of oscula in response to environment, development and growth. Such mechanisms indicate morphological and physiological ... -
Distribution and geochemical fractionation of lead in the continental shelf sediments around India
(2019)This study provides the first, preliminary data on geochemical distribution and fractionation of Pb (a toxic heavy metal) in continental shelf sediments around India and identifies the factors that control geochemical ... -
Bacterial Community Composition Markedly Altered by Coastal Hypoxia
(2019)Monsoonal upwelling along south and central west coast of India leads to intense biological productivity. As a consequence of excess organic matter production following upwelling during June-October and low dissolved oxygen ... -
Uncertainties of the 50-year wave height estimation using generalized extreme value and generalized Pareto distributions in the Indian Shelf seas
(2019)Information about waves with specific return period in a region is essential for the safe design of marine facilities. In this study, significant wave height for 50-year return period is estimated using generalized extreme ... -
Coral reef restoration - A way forward to offset the coastal development impacts on Indian coral reefs
(2019)Globally, coral reefs are degrading rapidly due to the combined impact of wide-scale anthropogenic activities and climate change. Similarly, coral reefs in India are facing an existential threat because of intensified ... -
Microbial diversity in a coastal environment with co-existing upwelling and mud-banks along the south west coast of India
(2019)Upwelling and mud banks are two prominent oceanographic features in the coastal waters along the south west coast of India during the southwest monsoon (MON) season. The present study investigates the microbial diversity ... -
Distribution and dispersal of surface sediments on the continental margins of India
(2019)The vast area, varying climate regimes, diverse source terrain lithology of the mainland India generate complex weathering and erosional patterns and leads to diverse sediment distribution and dispersal on the surrounding ... -
Spatio-temporal variability in macrobenthic communities and trophic structure of a tropical estuary and its adjacent coastal waters
(2019)Spatio-temporal distribution of the macrobenthic community (> 500 ?m) and the trophic ecology of polychaetes were studied for a year in the Cochin estuary (CE) and its adjacent coastal waters. A profound influence of the ...
