Total petroleum hydrocarbon in the tissues of some commercially important fishes of the Bay of Bengal
(Elsevier, 2012)The level of total petroleum hydrocarbon (TPH) in 27 commercially important fish, crustaceans and cephalopods are reported from Orissa coast, Bay of Bengal to provide the baseline data for oil contamination in marine biota. ... -
A new species of the genus Acarothrix (Acari: Halacaridae) from Brunei Darussalam and India
(Station Biologique de Roscoff, 2012)Acarothrix grandocularis sp. nov. is described from specimens collected in Brunei Darussalam and India. The new species is characterized by the presence of dorsal seta 1 on the posterior part of anterior dorsal plate, a ... -
Tracing the Paleo sulfate-methane transition zones and H2S seepage events in marine sediments: An application of C-S-Mo systematics
(American Geophysical Union, 2012)Microbially mediated anaerobic oxidation of methane (AOM) coupled with sulfate consumption within the sulfate methane transition zone (SMTZ) in marine sediments is a widely recorded biogeochemical reaction and has profound ... -
Online Stable Isotope Analysis of Dissolved Organic Carbon Size Classes Using Size Exclusion Chromatography Coupled to an Isotope Ratio Mass Spectrometer
(American Chemical Society, 2012)Stable isotopic content of dissolved organic carbon (delta sup(13)C-DOC) provides valuable information on its origin and fate. In an attempt to get additional insights into DOC cycling, we developed a method for delta ... -
Fractionation and fragmentation of glass cosmic spherules during atmospheric entry
(Elsevier, 2012)Glass cosmic spherules are a sub-type of S-type cosmic spherules that are almost at the end phase of fractionation and volatilization during atmospheric entry. A focused investigation of 36 glass spherules out of several ... -
Study of aerosol optical thickness using MODIS satellite data and sun photometer in a part of West coast of India
(Cafet-Innova Technical Society, 2012)The knowledge of aerosol optical properties plays an important role in estimation of the direct aerosol forcing. The aerosol optical thickness obtained from MODIS and Microtops II Sunphotometer is described. The data has ... -
Seamounts - characteristics, formation, mineral deposits and biodiversity
(Biblioteca de Geologia (UB-CSIC), 2012)Seamounts represent crust-mantle activities and are areas of petrological deviations, biodiversity, seismicity and hydrothermal events. An estimated approx. 50 million tons/year of basalts are required to produce seamounts ... -
Primary productivity and nitrogen fixation by Trichodesmium spp. in the Arabian Sea
(Elsevier, 2012)Trichodesmium was studied with the purpose of understanding its distribution, organic production and nitrogen fixation in the Arabian Sea. Out of the 143 stations sampled, a total of 93 stations showed the presence of ... -
Geochemical and geological constraints on the composition of marine sediment pore fluid: Possible link to gas hydrate deposits
(Elsevier, 2012)Pore water sulfate consumption in marine sediments is controlled by microbially driven sulfate reduction via organo-clastic and methane oxidation processes. In this work, we present sediment pore fluid compositions of 10 ... -
Extreme sea-level events in coastal regions
(Current Science Association, 2012)Underlines the need for documentation of the adaptation practices from previous extreme events for handling future exigencies in the coastal regions. -
A new species of Litarachna Walter, 1925 (Acari: Hydrachnidia) from the West Indian Coast, with a discussion on the diversity of the family Pontarachnidae Koenike, 1910
(Station Biologique de Roscoff, 2012)Litarachna indica, a new species of the marine water mite family Pontarachnidae (Acari: Hydrachnidia) is described from the tropical West Indian coast. The total number of Pontarachnidae species worldwide tallies exactly ... -
Phosphate solubilizing bacteria and alkaline phosphatase activity in coastal waters off Trivandrum
(Centre for Ocean and Environmental Studies, New Delhi, 2012)Phosphorus is a key nutrient in marine environment. Phosphate solubilising bacteria (PSB) have the ability to solubilise ionic forms of orthophosphoric acid to free form of phosphrous in the water column. Both PSB and ... -
Monsoonal variability in abiotic parameters in coastal waters off Trivandrum evokes press and pulse response in biotic variables
(Centre for Ocean and Environmental Studies, New Delhi, 2012)Trivandrum Coast experiences coastal upwelling during south west monsoon, which is accompanied by abiotic changes in physio-chemical parameters. The resultant biotic responses could range from an instantaneous pulse to a ... -
Glacially derived material in an Inner Mongolian desert lake during Marine Isotope Stage 2
(John Wiley, 2012)Establishing the precise timing of continental glacial dynamics and abrupt high-latitude climate events is crucial to understanding the causes of global climate change. Multi-proxy records in a lake sediment core from arid ... -
Record of bi-operculate fouling serpulid polychaete, Hydroides operculatus (Treadwell, 1929) from Diu, west coast of India
(CSIR-NISCAIR, 2012)The bi-operculate form of fouling serpulid polychaete, Hydroides operculatus Treadwell, 1929 was studied. This variant was found in samples collected from Diu, North West coast of India. A perusal of literature indicates ... -
Effect of temperature, salinity and biofilm on the zoospores settlement of Enteromorpha flexuosa (Wulfen) J.Agardh
(CSIR-NISCAIR, 2012)The effect of temperature (10-30 degrees C), salinity (15-35 psu) and biofilm on the settlement of Enteromorpha flexousa zoospores was assessed. Settlement of zoospores was significantly (p less than 0.05) influenced by ... -
Tide dependent seasonal changes in water quality and assimilative capacity of anthropogenically influenced Mormugao harbour water
(CSIR-NISCAIR, 2012)Water quality data from Mormugao harbour area at the mouth of Zuari estuary in Goa have been obtained over two tidal cycles monthly for the year 2003 to 2004. R-mode factor analyses of the data indicated strong positive ... -
Study of ecological consequence of the bloom (Noctiluca miliaris) in off shore waters of the Northern Arabian Sea
(CSIR-NISCAIR, 2012)Ship based observations during early March 2007 in oceanic waters of the Northeastern Arabian Sea followed by phytoplankton analysis indicated that the bloom Noctiluca miliaris, species of dinoflagellate, dominated oceanic ... -
Is an onset vortex important for monsoon onset over Kerala?
(Springer, 2012)Inter-annual variability in the formation of the mini warm pool [sea-surface temperature (SST) more than 30 degrees C] over the south eastern Arabian Sea (SEAS) and its role in the formation of the monsoon onset vortex ... -
