Biodiversity and community structure of freeliving marine nematodes from the Larsemann Ice Shelf, East Antarctica
(Current Science Association, 2010)Subtidal (500-700 m) meiofaunal assemblage of the Larsemann Ice Shelf, East Antarctica, is described with special emphasis on the free-living marine nematodes. The sampling was conducted with a 25 x 25 x 40 cm VSNL Spade ... -
Intra-annual variability in nutrients in the Godavari estuary, India
(Elsevier, 2010)Daily variations in nutrients were monitored for 15 months (September 2007-November 2008) in the Godavari estuary, Andhra Pradesh, India, at two fixed locations. River discharge has significant influence on nutrients loading ... -
Seasonal cycle of physical forcing and biological response in the Bay of Bengal
(NISCAIR, CSIR, 2010)Seasonal cycle of the physical processes and the biological response in the Bay of Bengal were studied using co-located physical, chemical and biological data collected along the central and the western Bay covering four ... -
Seasonal variability in biological carbon biomass standing stocks and production in the surface layers of the Bay of Bengal
(NISCAIR, CSIR, 2010)As a part of the Bay of Bengal Process Study, several biological characteristics were investigated during summer monsoon (SuM; July-August 2001), fall inter monsoon (FIM, September-August 2002), spring inter monsoon (SpIM; ... -
Land-ocean tectonics (LOTs) and the associated seismic hazard over the Eastern Continental Margin of India (ECMI)
(Springer, 2010)The South Indian (Peninsular) Shield which includes both the Eastern and Western Continental Margins of India is not as stable as it was originally thought of. The importance of intraplate seismicity within this Shield has ... -
What do barnacle larvae feed on ? Implications in biofouling ecology
(Marine Biological Association of the United Kingdom, 2010)Barnacles are one of the dominant macrofouling organisms found in the intertidal region throughout the world. Among the different species of barnacles Balanus amphitrite (= Amphibalanus amphitrite) is a favoured candidate ... -
Indian monsoon cycles through the last twelve million years
(The society of Earth Scientists, 2010)Although Indian monsoon mostly sets on in early June, it often deceives with vagaries of droughts or floods causing hardship to millions in the Indian subcontinent. It varies at the intra-monsoonal scale with 40-50 days ... -
Quantification of the energy required for the destruction of Balanus Amphitrite larva by ultrasonic treatment
(Marine Biological Association of the United Kingdom, 2010)Ultrasonic treatment, a relatively less explored technology in water disinfection, was used to quantify the energy required for the destruction of larvae of barnacle Balanus amphitrite, which is a major marine fouling and ... -
A global census of marine microbes
(Wiley-Blackwell, 2010)In this chapter we provide a brief history of what is known about marine microbial diversity, summarize our achievements in performing a global census of marine microbes, and reflect on the questions and priorities for the ... -
Variations in long term wind speed during different decades in Arabian Sea and Bay of Bengal
(Indian Academy of Sciences, 2010)A study has been carried out by comparing the extreme wind speeds estimated based on NCEP/NCAR reanalysis data for 100 years return period using Fischer Tippet-1 (commonly known as Gumbel) and Weibull distributions for ... -
Nitrate reduction by fungi in marine oxygen-depleted laboratory microcosms
(Walter de Gruyter, 2010)Fungi are major contributors to the process of denitrification in terrestrial environments, but their role as denitrifiers in the ocean has not been addressed thus far. The nitrate reducing capacity of fungi based on ... -
Presence of 60Fe in eucrite Piplia Kalan: A new perspective to the initial 60Fe/ 56Fe in the early solar system
(Current Science Association, 2010)Fe-Ni isotope measurements of ferrous pyroxenes of the Piplia Kalan eucrite using Secondary Ion Mass Spectrometer revealed the presence of sup (60) Ni excess corresponding to the initial 60Fe/56Fe of (5.2 + or - 2.4) × 10 ... -
Short-term variability of water quality and its implications on phytoplankton production in a tropical estuary (Cochin backwaters - India)
(Springer, 2010)Changes in the phytoplankton biomass (chlorophyll a), production rate, and species composition were studied over two seasons using the time series measurements in the northern limb of the Cochin estuary in relation to the ... -
Biogeochemistry of lead in the eastern Arabian Sea and western Bay of Bengal
(Taylor & Francis, 2010)Biogeochemical cycling of lead (Pb) within the Indian Exclusive Economic Zone of the Arabian Sea and Bay of Bengal was examined in terms of the dissolved and particulate Pb concentration profiles. The relative distribution ... -
New evidence on the sequence of deglacial warming in the tropical Indian Ocean
(John Wiley, 2010)The transition from the Last Glacial Maximum to the Holocene was an internal of climate variability that was characterised by large spatial and temporal variations. Here we show that deglaciation warming in the northern ... -
Mysids (Crustacea) from the salt pans of Mumbai, India, with a description of a new species
(Taylor & Francis, 2010)The taxonomy, distribution and ecology of mysids collected from the salt pans of Mumbai, India, were studied. Two mysid species are represented, of which one species, Indomysis nybini, is described as new to science. The ... -
A new species of portunid crab of the genus Charybdis (De Haan, 1833) (Crustacea: Decapoda: Brachyura) from Goa, India
(Taylor & Francis, 2010)A new species of portunid crab, Charybdis (Charybdis) goaensis sp. nov. is described from Goa, west coast of India. It differs from its closest congener, Charybdis (Charybdis) philippinensis in possessing bluntly triangular ... -
Large fault fabric of the Ninetyeast Ridge implies near-spreading ridge formation
(American Geophysical Union, 2010)Ninetyeast Ridge (NER) is a linear volcanic ridge in the Indian Ocean thought to have formed by hotspot volcanism on the northward?drifting Indian plate. Geological data from the ridge are sparse, so its tectonic evolution ... -
Changes in abundance and nature of microimpact craters on the surfaces of Australasian microtektites with distance from the proposed source crater location
