Attenuation of Wave Energy Due to Mangrove Vegetation off Mumbai, India
(2019)Coastal regions of India are prone to sea level rise, cyclones, storm surges, and human-induced activities, resulting in flood, erosion, and inundation, and some of these impacts could be attributed to climate change. ... -
Determination of spatio-temporal influences on the distribution of fecal indicator organisms along the north-west coast of India
(2019)Coastal ecosystem is susceptible to discharge of untreated sewage waste. The present study is aimed to determine water quality status prevailing along the northwest coast of India by monitoring spatial and temporal variations ... -
Long-Term Variations in Nearshore Wave Climate and Littoral Drift at Ganpatipule Coast, Eastern Arabian Sea and its Link to Pacific Climate Variability
(2019)Nearshore wave characteristics and its variations at Ganpatipule coast, eastern Arabian Sea, for the past 4 decades (1979-2016) have been examined. The study is based on European Centre for Medium-Range Weather Forecasts ... -
Looking for the Harappan Ports around Dholavira, Khadir Bet, Kachchh, Gujarat
(2019)The rise of Harappan settlement at Dholavira is attributed to multidimensional factors which may include industrial activities, overseas trade and commerce and distribution of resources available in the Kachchh to other ... -
Did Romans have direct maritime trade contacts with Odisha on the Eastern Indian littoral?
(2019)Kalinga, Utkal, Odra and Orissa are former names of the present state of Odisha with varied geographical boundaries in different periods of history. The exploration and excavations of Manikapatna, Palur, Radhanagar, ... -
Chromium speciation in the sediments across the oxygen minimum zone, western continental margin of India
(2019)This study suggests that varying concentration of dissolved oxygen of overlying bottom water influences geochemical fractionation, speciation, and oxidation state of sedimentary Cr in a marine system. The nature of sedimentary ... -
Multidisciplinary Observing in the World Ocean�s Oxygen Minimum Zone Regions: From Climate to Fish - The VOICE Initiative
(2019)Multidisciplinary ocean observing activities provide critical ocean information to satisfy ever-changing socioeconomic needs and require coordinated implementation. The upper oxycline (transition between high and low oxygen ... -
Diversity and extracellular enzyme activities of heterotrophic bacteria from sediments of the Central Indian Ocean Basin
(2019)Sedimentary bacteria play a role in polymetallic nodule formation and growth. There are, however, limited reports on bacterial diversity in nodule-rich areas of the Central Indian Ocean Basin (CIOB). In this study, bacterial ... -
Anthropogenic spherules in Zuari estuary, south west coast of India
(2019)In this study we report silica rich anthropogenic spherules from the marine environment. We found spherical, dumbbell, teardrop and fused spherules in Zuari estuary (near the Dona paula jetty), south west coast of India. ... -
Changes in Wave Energy in the Shelf Seas of India during the Last 40 Years Based on ERA5 Reanalysis Data
(2019)Ocean wave energy is one of the cleanest renewable energy sources around the globe, but wave energy varies widely from place to place and from time to time. The long-term variability of wave power at 20 locations in the ... -
Structure and emplacement of the Coastal Deccan tholeiitic dyke swarm in Goa, on the western Indian rifted margin
(2019)Mafic dyke swarms, when controlled by a regional stress field, are emplaced perpendicular to the minimum principal compressive stress direction. However, mafic dyke swarms may also exploit pre-existing structural fabric ... -
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 ...
