Bioremediation potential of hydrocarbon-utilizing fungi from select marine niches of India
(Springer, 2018)Ten fungal isolates with an ability to degrade crude oil were isolated from select marine substrates, such as mangrove sediments, Arabian Sea sediments, and tarballs. Out of the ten isolates, six belonged to Aspergillus, ... -
Polycyclic Aromatic Hydrocarbons (PAHs) and Hopanes in Plastic Resin Pellets as Markers of Oil Pollution via International Pellet Watch Monitoring
(Springer, 2017)Oil pollution in the marine environment is an unavoidable problem due to chronic input from local sources, particularly in urban areas and oil spills. Oil pollution not only causes immediate physical damages to surrounding ... -
Spatial and temporal distribution of metals in suspended particulate matter of the Kali estuary, India
(Elsevier, 2017)Major (Al, Fe, Mn, Ti, Mg) and trace (Cu, Zn, Pb, Cr, Ni, Co, Zr, Rb, Sr, Ba, Li, Be, Sc, V, Ga, Nb, Mo, Sn, Sb, Cs, Hf, Ta, Bi, Th, U) elements and particulate organic carbon (POC) concentrations in surface suspended ... -
Influence of short-term hydrographic variations during the north-east monsoon on picophytoplankton community structure in the eastern Arabian Sea
(Elsevier, 2017)The eastern Arabian Sea over the continental margin is a dynamic region subjected to short-term variability in hydrography as a result of various physical forcing such as coastal advection and vertical mixing. In order to ... -
Tropical Cyclone Genesis Potential Index for Bay of Bengal During Peak Post-Monsoon (October-November) Season Including Atmosphere-Ocean Parameters
(Taylor & Francis, 2018)Several studies on tropical cyclone genesis potential index (GPI) mainly using atmospheric parameters (relative/absolute vorticity, relative humidity, vertical wind shear, potential instability, vertical velocity etc.) ... -
Global assessment of tropical cyclone intensity statistical-dynamical hindcasts
(Wiley, 2017)This paper assesses the characteristics of linear statistical models developed for tropical cyclone (TC) intensity prediction at global scale. To that end, multilinear regression models are developed separately for each ... -
Spatio-temporal variations in pathogenic bacteria in the surface sediments of the Zuari estuary, Goa, India
(Current Science Association, IAS, 2017)Estuaries are hotspots of anthropogenic activities. The deposition of pathogenic bacteria in the sediment and their re-suspension into the water column are influ-enced by riverine discharge and tides. The abundance of ... -
Wave energy dissipation due to mudbanks formed off southwest coast of India
(Elsevier, 2017)Mudbanks (MBs) are a unique natural phenomenon, and form along the southwest coast of India during the southwest monsoon. They are characterized by a calm-water region, bordered by a rough sea. In order to quantify the ... -
Intra-annual variations in phytoplankton biomass and its composition in the tropical estuary: Influence of river discharge
(Elsevier, 2018)To examine the influence of river discharge on phytoplankton composition, time-series observations were conducted at upper, middle and lower Godavari estuary during 2009. The salinity variations in the estuary were depended ... -
Major and trace metals in suspended and bottom sediments of the Mandovi and Zuari estuaries, western India: distribution, source, and pollution
(Springer, 2017)Major elements and trace metals in suspended sediments along transect stations of the Mandovi and Zuari estuaries showed three types of distribution: (a) high concentrations of most metals (Al, Fe, Mn, Cr, Pb, Cu, Ni, Zn, ... -
Variations in return value estimate of ocean surface waves - a study based on measured buoy data and ERA-Interim reanalysis data
(Copernicus Publications for EGU, 2017)An assessment of extreme wave characteristics during the design of marine facilities not only helps to ensure their safety but also assess the economic aspects. In this study, return levels of significant wave height (Hs) ... -
Early users of monsoon winds for navigation
(Current Science Association, IAS, 2017)The maritime history of India can be traced back to the Harappan Civilization. Studies suggest that even at that time, monsoon winds and currents assisted in navigation. Recent archaeological exploration and excavations ... -
Enzymatic saccharification of seaweeds into fermentable sugars by xylanase from marine Bacillus sp. strain BT21
(Springer, 2017)Enzymatic hydrolysis of seaweed biomass was studied using xylanase produced from marine bacteria Bacillus sp. strain BT21 through solid-state fermentation of wheat bran. Three types of seaweeds, Ahnfeltia plicata, Padina ... -
Dominance of coastal upwelling over Mud Bank in shaping the mesozooplankton along the southwest coast of India during the Southwest Monsoon
(Pergamon, 2017)Mud Banks are littoral zones along the Kerala (southwest) coast of India with increased suspended sediments during the Southwest Monsoon (SWM), which facilitate remarkable damping of incident waves creating a localized ... -
Seasonal variation in bacterial community composition and Seasonal variation in bacterial community composition and β-glucosidase expression in a tropical monsoon-influenced estuary
(Inter Research, 2017)Tidal estuaries receive carbohydrate-rich organic matter from various sources, which are mainly broken down by enzymatic processes. ?-glucosidase (?-Glu) is one of the ectoenzymes produced by heterotrophic bacteria. An ... -
Robustness of observation-based decadal sea level variability in the Indo-Pacific Ocean
(Wiley, 2017)We examine the consistency of Indo-Pacific decadal sea level variability in 10 gridded, observation-based sea level products for the 1960-2010 period. Decadal sea level variations are robust in the Pacific, with more than ... -
Defaunation of meiofauna in Mumbai bay (India) - A severely polluted area
(Elsevier, 2017)Meiofauna plays an important role in the benthic food web of shallow water ecosystems. In the present study, the status of meiofauna was addressed in the intertidal and subtidal environment of Mumbai bay (West coast of ... -
Diversity of sediment-associated Planctomycetes in the Arabian Sea oxygen minimum zone
(Wiley, 2017)We examined the diversity of Planctomycetes in the sediment sample collected from an oxygen minimum zone (OMZ) in the southeast Arabian Sea. A 16SrRNA gene library was constructed using the forward primer specific for ... -
Intense reducing conditions during the last deglaciation and Heinrich events (H1, H2, H3) in sediments from the oxygen minimum zone off Goa, eastern Arabian Sea
(Elsevier, 2017)Two sediment cores, ABP-32/GC-01R and ABP-32/GC-03 were collected at a water depth of 642 m and 1086 m off Goa from the present day Oxygen Minimum Zone (OMZ) of eastern Arabian Sea (EAS) cover time span of last 18 ka and ... -
Increased CO 2 availability promotes growth of a tropical coastal diatom assemblage (Goa coast, Arabian Sea, India)
(Taylor & Francis, 2017)Responses of tropical coastal phytoplankton assemblages to increasing CO2 levels are poorly known. The Arabian Sea (AS), the western part of the north Indian Ocean, is an upwelling-induced, highly productive region, but ...
