Myctophid and pelagic shrimp assemblages in the oxygen minimum zone of the Andaman Sea during the winter monsoon
(NISCAIR (CSIR), 2011)Stratified samples were collected with a Multiple Plankton Net for assessing the myctophid and pelagic shrimps composition from the Andaman Sea during the winter monsoon. Andaman Sea has a fair representation of mesopelagic ... -
Effects of composition of labile organic matter on biogenic production of methane in the coastal sediments of the Arabian Sea
(Springer, 2011)Coastal regions are potential zones for production of methane which could be governed by ecological/environmental differences or even sediment properties of a niche. In order to test the hypothesis that methanogenesis in ... -
Pulleniatina Minimum Events in the Andaman Sea (NE Indian Ocean): Implications for winter monsoon and thermocline changes
(Elsevier, 2011)The late Quaternary record of Pulleniatina obliquiloculata was investigated from two well dated sediment cores from the Andaman Sea (NE Indian Ocean) to examine its paleoceanographic significance and the presence of the ... -
Bacterial utilization of size-fractionated dissolved organic matter
(Inter-Research, 2011)Dissolved organic matter (DOM) is an important source of organic carbon for sustaining the growth of heterotrophic bacteria. The bacterial utilization of high-molecular-weight (HMW; greater than 30 kDa to 0.22 mu m) and ... -
A study of traditional boats of Goa
(Indian Society for Prehistoric and Quaternary Studies, 2011)Goa, being situated along the Arabian Sea of India, is known for maritime activities and traditional boat building throughout the history. Traditional folk songs of Goa frequently mention ‘Vodem’ which denotes canoe. The ... -
Manganese Oxidation by Bacteria: Biogeochemical Aspects
(Springer-Verlag, 2011)Manganese is an essential trace metal that is not as readily oxidizable like iron. Several bacterial groups posses the ability to oxidize Mn effectively competing with chemical oxidation. The oxides of Mn are the strongest ... -
Model-based acoustic remote sensing of seafloor characteristics
(IEEE, 2011)The characterization of seafloor sediments by acoustic means is carried out using normal-incidence, dual-frequency, single-beam echo sounder backscatter data at 20 locations in the western continental shelf of India. A ... -
Development of the negative gravity anomaly of the 85 degrees E Ridge, northeastern Indian Ocean – A process oriented modelling approach
(Indian Academy of Sciences, 2011)The 85 degrees E Ridge is associated with two contrasting gravity anomalies: negative anomaly over the north part (up to 5 degrees N latitude), where the ridge structure is buried under thick Bengal Fan sediments and ... -
On the dominance of pre-existing swells over wind seas along the west coast of India
(Elsevier, 2011)Wave data collected off Goa along the west coast of India during February 1996–May 1997 has been subjected to spectral analysis, and swell and wind sea parameters have been estimated by separation frequency method. Dominance ... -
Vulnerability of freshwater fisheries and impacts of climate change in south Indian states economies
(Inderscience Enterprises, 2011)The vulnerability of five states in India national economies to potential climate change impacts on their capture fisheries using an indicator-based approach were compared. The states: Karnataka, Tamilnadu, Andhrapradesh, ... -
Effect of background color of tanks on growth and survival of juvenile Yellow Seahorse, Hippocampus kuda (Bleeker 1852), in the pelagic phase
(The Society of Israeli Aquaculture and Marine Biotechnology, 2011)This communication reports the results of an experiment conducted to see if background tank color affects the growth and survival of juvenile H. kuda. Juveniles were reared from 0 to 21 days after birth (DAB) in one of six ... -
Physical properties, morphology and petrological characteristics of pumices from the Central Indian Ocean Basin
(Geological Society of China, 2011)About 400 pumice clasts collected from the Central Indian Ocean Basin (CIOB) were studied for their morphology and classified based on their shape and size. A majority of the samples range between less than 1 cm and 36 cm ... -
Variations in tidal constituents along the nearshore waters of Karnataka, west coast of India
(Coastal Education & Research Foundation, 2011)The characteristics of tidal constituents along the nearshore waters of Karnataka, west coast of India, are described. These are based on the sea level data measured at three locations by the Valeport wave and tide gauge ... -
Meso-scale atmospheric events promote phytoplankton blooms in the coastal Bay of Bengal
(Indian Academy of Sciences, 2011)The Bay of Bengal is considered to be a low productive region compared to the Arabian Sea based on conventional seasonal observations. Such seasonal observations are not representative of a calendar year since the conventional ... -
Spatial distribution and longitudinal variation of clay minerals in the Central Indian Basin
(Geological Society of China, 2011)Grain size and clay mineral distribution up to 45 cm depth in the silty clay sediments from 26 box cores from 10 degrees to 16 degrees S along four longitudes (73.5 degrees-76.5 degrees E) were studied for understanding ... -
A review on mesopelagic fishes belonging to family Myctophidae
(Springer, 2011)Myctophids are mesopelagic fishes belonging to family Myctophidae commonly called as 'Lanternfishes', Ecologically, myctophids link primary consumers like copepods, euphausiids and top predators like squids, whales and ... -
The response of a natural phytoplankton community from the Godavari River Estuary to increasing CO2 concentration during the pre-monsoon period
(Elsevier, 2011)The effects of increasing CO sub(2) concentrations on a natural phytoplankton assemblage in a tropical estuary (Godavari, India) is reported. Two short-term (5-day) bottle experiments were conducted (with and without ... -
