New species of marine littoral mites (Acari: Oribatida) from Taiwan and India, with a key to the world's species of Fortuynia and notes on their distribution
(Academia Sinica, 2009)Species of the small oribatid mite genus <i>Fortuynia</i> (Ameronothroidea: Fortuyniidae) mostly inhabit marine littoral zones in the tropics and subtropics. In the present paper, we describe 2 new species, <i>Fortuynia ... -
Darwin core based data streamlining with digimus 2.0
(University of Kansas, 2009)Cataloguing biological specimen is an important activity of biological museums world over. Software developed especially for this purpose has evolved over time to achieve more accuracy in retrieving data from large and ... -
Spatiotemporal structure of the East India Coastal Current from satellite altimetry
(American Geophysical Union, 2009)A newly processed altimeter data set to present a hitherto unprecedented description of the spatiotemporal structure of the East India Coastal Current (EICC) is used: the data set resolves timescales ranging from a few ... -
Increasing trend of `Break-Monsoon` conditions over India — Role of ocean–atmosphere processes in the Indian Ocean
(IEEE, 2009)Analysis of daily rainfall data over India during the period 1951–2007 reveal an increased propensity in the occurrence of `monsoon-breaks` over the subcontinent. The increasing trend is seen both in the duration and ... -
A study on the effects of some laboratory-derived genetic mutations on biofilm formation by Listeria monocytogenes
(Springer, 2009)Biofilms formed by the human pathogen Listeria monocytogenes in food-processing environments can be a potential source of contamination. In this study, we investigated the ability of L. monocytogenes wild type and its ... -
Observed thermohaline structure and cooling of Kochi backwaters and adjoining southeastern Arabian Sea
(Current Science Association, 2009)Thermohaline structure of Kochi backwaters under fair and rough weather conditions has been examined along with thermal structure of two open-ocean islands in the adjoining southeastern Arabian Sea (Kavaratti and Andrott ... -
An investigation into the conditions leading to monsoon onset over Kerala
(Springer, 2009)Monsoon onset over the Kerala (MOK) coast has been studied using the recently released high resolution Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite data (HOAPS 3). Columnar water vapour content, sea surface ... -
Radiocarbon dates of the medieval period stone anchors from Dabhol, west coast of India
(Current Science Association, 2009)Dabhol was an important medieval-period port town on the Maharashtra coast. An archaeological exploration at Dabhol has revealed four stone anchors with remains of wood in fluke hole. These anchors were retrieved from ... -
Radiolarian abundance - A monsoon proxy responding to the Earth`s orbital forcing: Inferences on the mid-Brunhes climate shift
(The Society of Earth Scientists, 2009)Radiolarian fluxes from the sediment traps moored in the southern Bay of Bengal suggested that radiolarians were invariably higher at times of higher sea surface temperature (SST greater than or equal to 28 degrees C) and ... -
Elysia bangtawaensis Swennen (Nudibranch) from the mangrove habitat of Mandovi estuary, Goa (central west coast), India
(Current Science Association, 2009)Elysia bangtawaensis has been reported from India, contributing towards biodiversity. Ecological observations revealed its exclusive association to the mangrove swamp from the midreaches of the Mandovi estuary, Goa, India. ... -
Chemical characterization of a marine conditioning film
(Elsevier, 2009)Conditioning film grown on glass panels was analyzed for organic carbon and nitrogen, total carbohydrates, aldoses, uronic acids, and proteins. These compounds showed non-linear increase over the periodof immersion. Total ... -
Antifouling activity exhibited by secondary metabolites of the marine sponge, Haliclona exigua (Kirkpatrick)
(Elsevier, 2009)Bioassay guided purification of the acetone extract of the marine sponge, Haliclona exigua, (Gulf of Mannar, India) yielded a fraction rich in bis-1-oxaquinolizidine alkaloids, active against seven strains of fouling ... -
Seasonally varying nitrogen isotope biogeochemistry of particulate organic matter in Lake Kinneret, Israel
(American Society of Limnology and Oceanography, 2009)Large temporal variations in the nitrogen isotopic composition (delta sup(15) N) of particulate organic matter (POM) and dissolved inorganic nitrogen (DIN) species in Lake Kinneret occurred in response to seasonal phasing ... -
Geochemical variability of copper and iron in Oman margin sediments
(Elsevier, 2009)An analysis of the geochemical distribution of selected trace metals among various geochemical phases of the sediments in the Oman Margin was carried out using a sequential extraction technique. The present study showed ... -
