The effects of prolonged darkness on temperate and tropical marine phytoplankton, and their implications for ballast water risk management
(Elsevier, 2011)Phytoplankton assemblages from tropical (Goa) and temperate (UK) locations were exposed to a 28 day dark period, followed by a period of re-exposure to light. During this time phytoplankton survival and changes in nutrient ... -
Population structure and reproductive biology of Mesopodopsis orientalis (Crustacea: Mysida) in a tropical mangrove ecosystem in India
(Marine Biological Association of the United Kingdom, 2011)The population structure and biological aspects of the shallow water mysid Mesopodopsis orientalis were studied in the Versova mangrove, Mumbai, India. The monthly collections ranged from 0-2104 ind.m sup (-3)with an average ... -
Epi-benthic megafaunal zonation across an oxygen minimum zone at the Indian continental margin
(Elsevier, 2011)The Arabian Sea oxygen minimum zone (OMZ) impinges upon the Indian continental margin at bathyal depths (150–1500 m) producing changes in ambient oxygen availability and sediment geochemistry across the seafloor. The ... -
Difference in optimum temperature for growth and reproduction in benthic foraminifer Rosalina globularis: Implications for paleoclimatic studies
(Elsevier, 2011)The seawater temperature is an important physical parameter that affects marine benthic community. The effect of seawater temperature however is not consistent throughout various groups of marine benthos. Here, juvenile ... -
Observational evidence of lower-frequency Yanai waves in the central equatorial Indian Ocean
(American Geophysical Union, 2011)Analysis of long time series of current meter data from a mooring at 77 degrees E and the equator during 2003–2007, along with mean sea level anomaly data, throws light on the occurrence of the lower-frequency (24 to 40 ... -
Predominance of anaerobic bacterial community over aerobic community contribute to intensify ‘oxygen minimum zone’ in the eastern Arabian Sea
(Elsevier, 2011)The presence of a delicately poised mid-depth oxygen minimum zone (OMZ) makes the Arabian Sea a unique and important ecosystem. So far, various aspects responsible for its formation have been studied. However, the contributions ... -
Trace metal dynamics in marine shrimps from the southwest coast of India
(Taylor & Francis, 2011)Concentrations of Fe, Co, Ni, Cu, Zn, Cd and Pb in the muscle tissue of marine shrimps, Penaeus mondon, Penaeus japonicus, Penaeus indicus, Penaeus mergniensis, Parapenaeopsis hardwickii and Parapenaeopsis stylifera, ... -
Physical and biological response of the Arabian sea to tropical cyclone Phyan and its implications
(Elsevier, 2011)The response to the tropical cyclone Phyan, which developed in the eastern Arabian Sea during 9–11 November 2009, was rapid cooling of sea surface temperature (SST), enhancement of chlorophyll a and two-fold increase in ... -
Influence of morphodynamic variability over seasonal beach sediments and its probable effect on coastal development
(Elsevier, 2011)Seasonal variations and effect of oceanographic processes such as erosion and/or accretion along beaches are important to understand their impact on coastal morphological variations. Detailed investigations were taken up ... -
Extinction risk assessment of the world’s seagrass species
(Elsevier, 2011)Seagrasses, a functional group of marine flowering plants rooted in the world’s coastal oceans, support marine food webs and provide essential habitat for many coastal species, playing a critical role in the equilibrium ... -
Dynamics of chromophoric dissolved organic matter in Mandovi and Zuari estuaries — A study through in situ and satellite data
(Elsevier, 2011)The spatial and temporal distribution of absorption of chromophoric dissolved organic matter at 440 nm (a sub (CDOM) (440)) in the Mandovi and Zuari estuaries situated along the west coast of India, has been analysed. The ... -
Hot spot activity and tectonic settings near Amsterdam–St. Paul plateau (Indian Ocean)
(American Geophysical Union, 2011)The Amsterdam–St. Paul (ASP) plateau is located in the central part of the Indian Ocean and results from the interaction between the ASP hot spot and the Southeast Indian Ridge (SEIR). It is located near the diffuse boundary ... -
Ion microprobe analyses of oxygen three-isotope ratios of chondrules from the Sayh al Uhaymir 290 CH chondrite using a multiple-hole disk
(Wiley-Blackwell, 2011)The ion microprobe is the only technique capable of determining high-precision stable isotope ratios in individual tiny extraterrestrial particles (less than or equal to 100 mu m in diameter), but these small samples present ... -
Hybrid genetic algorithm tuned support vector machine regression for wave transmission prediction of horizontally interlaced multilayer moored floating pipe breakwater
(Centre for Infrastructure Engineering and Safety; Sydney; Australia, 2011)Support Vector Machine (SVM) works on structural risk minimization principle that has greater generalization ability and is superior to the empirical risk minimization principle as adopted in conventional neural network ... -
Spatial distribution of the nematodes in the subtidal community of the Central West Coast of India with emphasis on Tershellingia longicaudata (Nematoda: Linhomoeidae)
(Taylor & Francis, 2011)Meiofaunal nematodes are among the most important components of the benthic environment. They have unusually high abundance and diversity. They are largely understudied in many parts of the world and explored very little ... -
Immobilisation of manganese, cobalt and nickel by deep-sea-sediment microbial communities
(Taylor & Francis, 2011)Box core samples BC26 and BC36 from geologically different settings were examined to test the hypothesis that autochthonous microbial communities from polymetallic-nodule-rich Central Indian Basin sediments actively ... -
