Marine organisms and their adaption - Adaptions solve the challenges of existence in the sea.
(Centre for Environmental Studies, 2009)Marine organisms exist in an ever-changing environment. The physical environment within the ocean varies with the availability of light, oxygen, food resources, pressure and temperature. This variation in the physical ... -
Marine vehicle path following using inner-outer loop control.
(IFAC International Conference, 2009)This paper addresses the problem of marine vehicle path following using innerouter loop control, with due account for the vehicle dynamics. We propose an inner-outer control structure that lends itself to a simple intuitive ... -
Seamounts - Their formation, mineral deposits, biodiversity and atmospheric oxygen.
(Indian Society for Earth, Planetary and Environmental Sciences (ISEPES), 2009)This article expounds on (1) the production and distribution of seamounts in the formation of mineral deposits and (2) the influence of seamounts in the spatial variation of organisms -
Deep-water chemosynthetic ecosystem research during the Census of Marine Life decade and beyond: A proposed deep-ocean road map.
(PLoS, 2011)The ChEss project of the Census of Marine Life (2002-2010) helped foster internationally-coordinated studies worldwide focusing on exploration for, and characterization of new deep-sea chemosynthetic ecosystem sites. This ... -
Determination of Acetylcholinesterase activities in marine gastropod (Morula granulata) as a biomarker of neurotoxic contaminants along the Goan coast.
(Institute of Ecotoxicology and Environmental Sciences, 2011)Acetylcholinesterase (AChE) is an enzyme that degrades the neurotransmitter acetylcholine, producing choline and acetate. group. It is mainly found at neuromuscular junctions and cholinergic synapses in the central nervous ... -
Quantitative distribution of meiobenthos in the Gulf of Martaban, Myanmar Coast, north-east Andaman Sea
(CSIR-NISCAIR, 2014)Quantitative distribution of meiofauna in the depth range 20 to 1000 m of the Gulf of Martaban, Andaman Sea was studied from 46 stations during a synaptic survey carried out in April-May 2002 of ORV Sagar Kanya Cruise SK175 ... -
Spatial distribution and general population characteristics of Pseudanchialina pusilla (Crustacea: Mysida) in the eastern Arabian Sea
(Station Biologique de Roscoff, 2014)The distribution and general population characteristics of Pseudanchialina pusilla (Sars, 1883) were evaluated based on zooplankton collections obtained from different seasonal surveys conducted in 2004-2006 in the eastern ... -
Oscillating environmental responses of the eastern Arabian Sea
(CSIR-NISCAIR, 2014)Characteristics of two distinct physical processes, the coastal upwelling and convective overturning, which enhance phytoplankton productivity in the west coast of India, are discussed in this study. Systematic in-situ ... -
Dissimilatory nitrate reduction by Aspergillus terreus isolated from the seasonal oxygen minimum zone in the Arabian Sea
(BioMed Central, 2014)A wealth of microbial eukaryotes is adapted to life in oxygen-deficient marine environments. Evidence is accumulating that some of these eukaryotes survive anoxia by employing dissimilatory nitrate reduction, a strategy ... -
Grimontia indica AK16<sup>T</sup>, sp. nov., isolated from a seawater sample reports the presence of pathogenic genes similar to Vibrio Genus
(Public Library of Science, 2014)Grimontia indica strain AK16<sup>T</sup> sp. nov. is the type strain of G. indica sp. nov. a new species within the genus Grimontia. This strain, whose genome is described here, was isolated from seawater sample collected ... -
