Detoxification of toxic heavy metals by marine bacteria highly resistant to mercury
(Springer, 2008)Pollution in industrial areas is a serious environmental concern, and interest in bacterial resistance to heavy metals is of practical significance. Mercury (Hg), Cadmium (Cd), and lead (Pb) are known to cause damage to ... -
Purification and characterization of alpha-L-arabinofuranosidase from Arthrobacter sp. MTCC 5214 in solid-state fermentation
(Elsevier, 2008)Arthrobacter sp. MTCC 5214 produced an a-L-arabinofuranosidase when grown on solid-state fermentation (SSF). The enzyme was purified 19-fold using ion exchange and gel filtration chromatography. The enzyme had an apparent ... -
Fungi and macroaggregation in deep-sea sediments
(Springer, 2008)Whereas fungi in terrestrial soils have been well studied, little is known of them in deep-sea sediments. Recent studies have demonstrated the presence of fungal hyphae in such sediments but in low abundance. We present ... -
Sunken ships and a long-lost port
(Goa Publications, 2008)Considering that our region’s long seafaring history goes back 2,000 years and more, with a brisk trade being carried on with Arabia, Africa, Rome, West Asia, and later with Portugal, it is safe to assume that hundreds of ... -
Oceanographic data and information network in the Indian Ocean
(Kochi: School of Naval Oceanology and Meteorology, Southern Naval Command, 2004)Intergovernmental Oceanographic Commission (IOC) committee on International Oceanographic Data Exchange (IODE) has developed a data center network by establishing 70 National Oceanographic Data centres (NODCs) in 70 IOC ... -
Are the older ARGO-Floats more vulnerable to Fouling and Associated Salinity drift compared to that of later deployments?
(Kochi: School of Naval Oceanology and Meteorology, Southern Naval Command, 2004)Continued existence of ARGO floats for years together (4 year) make the conductivity cell more vulnerable to fouling and associated drift in salinity measurements In this paper, the authors address this issue by making use ... -
Elements of a coastal ocean forecasting system for India
(Kochi: School of Naval Oceanology and Meteorology, Southern Naval Command, 2004)After about four decades of investment in infrastructure for ocean research, an appropriate initiative for India now would be to build a coastal ocean forecasting system to support the country's myriad activities in its ... -
Tidal switch on metabolic activity: Salinity induced responses on bacterioplankton metabolic capabilities in a tropical estuary
(Elsevier, 2008)Biolog plates were used to study the changes in the metabolic capabilities of bacterioplankton over a complete tidal cycle in a tropical ecosystem (Cochin Estuary, Kerala, India) along southwest coast of India. The pattern ... -
Biogeochemical cycling in the Taiwan Strait
(Elsevier, 2008)Based on repeat observations made during 2001-2003 along two transects in the Taiwan Strait this study aims at understanding factors controlling primary productivity with an emphasis on biogeochemical cycling of nitrogen, ... -
Influence of allochthonous input on autotrophiceheterotrophic switch-over in shallow waters of a tropical estuary (Cochin Estuary), India
(Elsevier, 2008)Bacterial productivity (BP) and respiration (BR) were examined in relation to primary productivity (PP) for the first time in a shallow tropical ecosystem (Cochin Estuary), India. The degree of dependence of BP (6.3 199.7 ... -
Infaunal macrobenthic community of soft bottom sediment in a tropical shelf
(Coastal Education and Reserch Foundation, 2008)Studies of benthic communities in tropical shelf waters are limited. In this study, we deal with the infaunal benthic community of soft bottom sediment of the tropical eastern Arabian Sea shelf. Benthic macroinfauna was ... -
Observed anomalous upwelling in the Lakshadweep Sea during the summer monsoon season of 2005
(American Geophysical Union, 2008)Repeat near-fortnightly expendable bathythermograph (XBT) transects made along Kochi-Kavaratti (KK) shipping lane in the Lakshadweep Sea (LS) during 2002–2006 are examined to describe the observed year-to-year variability ... -
Spore germination of fungi belonging to Aspergillus species under deep-sea conditions
(Elsevier, 2008)Wind-blown dry fungal spores and mycelial fragments from the nearest landmass or terrestrial run-off may find their way to the deep sea by hitching a ride on other sinking detrital particles. Once in the deep, they are ... -
210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
(American Geophysical Union, 2008)Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ... -
Cellular-based and internet-enabled real-time reporting of the tsunami at Goa and Kavaratti Island due to Mw 8.4 earthquake in Sumatra on 12 September 2007
(Current Science Association, 2008)The tsunami at Goa (west coast of India) and Kavaratti Island (Lakshadweep archipelago) in the Arabian Sea, caused by the 12 September 2007 Sumatra earthquake, was reported from cellular-based sea-level gauges in real-time ... -
Impact of freshwater influx on the cyclogenesis, tracks of cyclones and air-sea coupling over the Bay of Bengal
(National Institute of Oceanography, India, 2008)Over the Bay of Bengal weather disturbances of considerable seasonal variability in their zones of genesis, intensity, frequency and path across the Bay generate during May-November. This variability in the zones of ... -
Preliminary results on the influence of river discharges on biogeochemical processes in Godavari estuary and Bay of Bengal
(National Institute of Oceanography, India, 2008)Preliminary results obtained form pilot experiments in Godavari estuary, Andhra Pradesh, India to understand the ecosystem and biogeochemical processes have been presented. During the southwest monsoon the estuary can be, ... -
Need of paleoclimatic reconstructions to understand natural and anthropogenic climatic hazards
(National Institute of Oceanography, India, 2008)To formulate the future plans for guarding against the furies of the nature, either due to natural or anthropogenic climatic disasters, understanding of paleoclimatic fluctuations, particularly of the Holocene is of immense ... -
Structure and tectonics of western continental margin of India: Implication for geologic hazards
(National Institute of Oceanography, India, 2008)The geomorphological and geological characteristics of Western Continental Margin of India (WCMI) are closely related to the tectonic history of the Indian subcontinent, its break up during continental rifting, magmatic ... -
