Impact of atmospheric and physical forcings on biogeochemical cycling of dissolved oxygen and nutrients in the coastal Bay of Bengal
(Springer, 2013)Time-series observations were conducted off Visakhapatnam, central west coast of Bay of Bengal, from October 2007 to April 2009 to examine the influence of physical and atmospheric processes on water column nutrients ... -
Operational forecast of oil spill trajectory and assessment of impacts on intertidal macrobenthos in the Dahanu region, west coast of India
(Coastal Education and Reserch Foundation, 2013)A two-dimensional model has been developed and applied to the hypothetical spills of crude oil in the Dahanu area on the west coast of India. An attempt has also been made to quantify the intertidal macrobenthic biomass ... -
Marine actinobacteria showing phosphate-solubilizing efficiency in Chorao Island, Goa, India
(Springer, 2013)The occurrence and distribution of an actinobacteria group of bacteria capable of dissolving insoluble phosphates were investigated in this study in marine environments, especially in sediments of Chorao Island, Goa, India. ... -
Coupling between suboxic condition in sediments of the western Bay of Bengal and southwest monsoon intensification: A geochemical study
(Elsevier, 2013)Reconstruction of paleo-redox conditions in a radiocarbon (14C) dated sediment core (SK-218/1), covering the past 45 ka (thousand calendar years), collected from the western Bay of Bengal (Lat: 14 degrees 02′N; Long: 82 ... -
Effect of freshwater influx on phytoplankton in the Mandovi estuary (Goa, India) during monsoon season: Chemotaxonomy
(Scientific Research Publishing, 2013)The Mandovi estuary is a prominent water body that runs along the west coast of India. It forms an estuarine network with the adjacent Zuari estuary, connected via the Cumbharjua canal. The physico-chemical conditions seen ... -
Diseases and parasites in cultured yellow seahorse, Hippocampus kuda (Bleeker, 1852)
(Fishing Chimes, 2013)Yellow seahorses that occur in the sea, because of their commercial importance are now cultured. But they are prone to diseases and parasites. The problems encountered in rearing of juveniles, solutions and treatments are ... -
Influence of winds on temporally varying short and long period gravity waves in the near shore regions of the eastern Arabian Sea
(European Geosciences Union, 2013)Wave data collected off Ratnagiri, west coast of India, during 1 May 2010 to 30 April 2012 are used in this study. Seasonal and annual variations in wave data controlled by the local wind system such as sea breeze and land ... -
Preliminary observation on breeding three spotted seahorse, Hippocampus trimaculatus (Leach, 1814), solely fed with wild caught amphipods under ex-situ condition
(Indian Council of Agricultural Research, 2013)The reproductive efficiency of the wild caught brooding seahorse population was compared with captive bred F1 generation. Aquaculture has been proposed as a solution to address sustainable trade in seahorse, and for ... -
Dissolved methane in Indian freshwater reservoirs
(Springer, 2013)Emission of methane (CH4), a potent greenhouse gas, from tropical reservoirs is of interest because such reservoirs experience conducive conditions for CH4 production through anaerobic microbial activities. It has been ... -
Synthesis of (R)-norbgugaine and its potential as quorum sensing inhibitor against Pseudomonas aeruginosa
(Elsevier, 2013)(R)-Bgugaine is a natural pyrrolidine alkaloid from Arisarum vulgare, which shows antifungal and antibacterial activity. We have accomplished the simple synthesis of norbgugaine (demethylated form of natural bgugaine) ... -
Trophic efficiency of plankton food webs: Observations from the Gulf of Mannar and the Palk Bay, Southeast Coast of India
(Elsevier, 2013)This paper introduces the structure and trophic efficiency of plankton food webs in the Gulf of Mannar (GoM) and the Palk Bay (PB) - two least studied marine environments located between India and Sri Lanka. The study is ... -
Difficulties in obtaining representative samples for compliance with the Ballast Water Management Convention
(Elsevier, 2013)As implementation of the Ballast Water Convention draws nearer a major challenge is the development of protocols which accurately assess compliance with the D-2 Standard. Many factors affect the accuracy of assessment: ... -
Observational Evidence of Summer Shamal Swells along the West Coast of India
(American Meteorological Society, 2013)Wave data collected off Ratnagiri, West coast of India, in 2010 and 2011 are used to examine the presence of the summer shamal swells. This study also aims to understand variations in wave characteristics and associated ... -
Ocean currents structuring the mesozooplankton in the Gulf of Mannar and the Palk Bay, southeast coast of India
(Elsevier, 2013)We hypothesis perceptible physical barriers that exist between the deep Gulf of Mannar and shallow Palk Bay located between India and Sri Lanka, and seasonally reversing surface circulation patterns in the region have a ... -
Open archiving of a ceased Indian journal: Inspired by third law
(CSIR-SERC, 2013)Before the commercial and impact factor journals ruled the publications industry, many institutes were showcasing their scholarly research output in the journals owned by them or by other institutes/societies. The CSIR-National ... -
Co-existence of wind seas and swells along the west coast of India during non-monsoon season
(European Geosciences Union, 2013)An attempt has been made to understand the co-existence of wind seas and swells along the west coast of India during non-monsoon season. Wave data were collected in different years during non-monsoon season (off Goa during ... -
Sea level trend and variability in the Singapore Strait
(European Geosciences Union, 2013)Sea level in the Singapore Strait (SS) exhibits response to various scale phenomena, from local to global. Longest tide gauge records in SS are analysed to derive local sea level trend and annual, inter-annual and multi-decadal ... -
Heavy metal tolerance in the psychrotolerant Cryptococcus sp. isolated from deep-sea sediments of the Central Indian Basin
