Anthropogenic activities including pollution and contamination of coastal marine environment.
(Academy of Environmental Biology, 2014)The term anthropogenic designates an effect or object resulting from human activity. the increasing economioc development and a rapidly growing population that has taken the country from 300 million people in 1947 to more ... -
Estimation of the barrier layer thickness in the Indian Ocean using Aquarius Salinity.
(American Geophysical Union, 2014)Monthly barrier layer thickness (BLT) estimates are derived from satellite measurements using a multilinear regression model (MRM) within the Indian Ocean. Sea surface salinity (SSS) from the recently launched Soil Moisture ... -
Massive outbreaks of Noctiluca scintillans blooms in the Arabian Sea due to spread of hypoxia.
(Macmillan, 2014)In the last decade, the northern Arabian Sea has witnessed a radical shift in the composition of winter phytoplankton blooms, which previously comprised mainly of diatoms, the unicellular, siliceous photosynthetic organisms ... -
Ambiguities in the classification of cochin estuary, West coast of India
(European Geosciences Union, 2013)Cochin Estuary is a unique complex system along Indian coastline with a widespread area at the upstream. The fluctuations in salinity are of extreme kind ranging from entirely riverine to entirely saline. The high runoff ... -
Evolution of cyclonic eddies and biogenic fluxes in the northern Bay of Bengal
(European Geosciences Union, 2013)The Bay of Bengal has been traditionally known for its low primary productivity and varied reasons were attributed to it. The data analysis from the sediment traps deployed in the northern Bay of Bengal during the 5 yr ... -
Decline in biodiversity of copepods in coastal waters of Mumbai
(MEDCOAST, 2013)Coastal waters of metropolitan cities face severe ecological threat due to sewage discharge and effluents from the industries. Copepods being the most abundant component in zooplankton some species can act as signals of ... -
Seasonal variations of nitrate reducing and denitrifying bacteria utilizing hexadecane in Mandovi estuary, Goa, West Coast of India
(CSIR-NISCAIR, 2013)Mandovi estuary has a prolific population of heterotrophic bacteria due to the influx of nutrients including nitrate and organic hydrocarbons. Seasonal sampling at various locations along the estuary was carried out to ... -
Experiment to decipher the effect of heavy metal cadmium on coastal benthic foraminifer Pararotalia Nipponica (Asano)
(Palaeontological Society of India, 2013)The response of benthic foraminifer Pararotalia nipponica to heavy metal cadmium is observed in laboratory experiment. The results indicate that under a given set of conditions, heavy metal cadmium is deleterious to benthic ... -
Natural hazards, disasters and human kind: Whither ecosystem management?
(Cafet-Innova Technical Society, 2013)Natural hazards such as yearly storm surges that create irreplaceable damage, the December 2004 tsunami that demolished large parts of the Indian coast, and the June 2013 Himalayan floods that swept river banks proved yet ... -
Adaptive wave filtering for dynamic positioning of marine vessels using maximum likelihood identification: Theory and experiments
(International Federation of Automatic Control, 2013)This paper addresses a filtering problem that arises in the design of dynamic positioning systems for ships and offshore rigs subjected to the influence of sea waves. The dynamic model of the vessel captures explicitly the ... -
Underwater target positioning with a single acoustic sensor
(International Federation of Automatic Control, 2013)The availability of reliable underwater positioning systems to localize one or more vehicles simultaneously based on information received on-board a support ship or an autonomous surface vessel is key to the operation of ... -
Magnetic navigation and tracking of underwater vehicles
(International Federation of Automatic Control, 2013)This paper proposes novel methods with the potential to improve the performance of navigation and tracking systems in underwater environments. The work relies on well-established methods of potential field inversion and ... -
Antifungal potential of marine sponge extract against plant and fish pathogenic fungi
(OMICS Group, 2013)he need for discovery of new antibiotics is imperative because previous evidence suggest that development of resistance to any new antimicrobial agents is inevitable. In addition, compounds not tested for antimicrobial ... -
Optimal Sensor placement for acoustic range-based underwater robotic positioning
(International Federation of Automatic Control, 2013)This paper addresses the problem of optimal sensor placement for acoustic range-based underwater target positioning. In particular, we focus on the experimental set-up whereby target positioning is ... -
Iron bacterial phylogeny and their execution towards iron availability in Equatorial Indian Ocean and Coastal Arabian Sea
(Polish Society of Microbiologists, 2013)Based on distinct colony morphology, color, size, shape and certain other traits, 92 bacterial isolates were investigated to understand their managerial ability on iron from the Arabian Sea and Equatorial Indian Ocean ... -
Sea level change
(P.M.Cambridge University Press, 2013)This chapter considers changes in global mean sea level, regional sea level, sea level extremes, and waves. Confidence in projections of global mean sea level rise has increased since the Fourth Assessment Report (AR4) ... -
Mathematical modeling of the evolution of a simple biological system
(India Environment Portal, Centre for Science and Environment, 2013)As a part of teaching of physics it is common to record data on evolution of a physical system and then construct a mathematical model of the system. For example, movement of a simple pendulum can be recorded, and then a ... -
A novel methodology for adaptive wave filtering of marine vessels: Theory and experiments
(IEEE, 2013)This paper addresses a filtering problem that arises in the design of dynamic positioning systems for ships and offshore rigs subjected to the influence of sea waves. The vessel`s dynamic model adopted captures the sea ... -
Distribution and sources of organic matter in surface sediments of the eastern continental margin of India
(American Geophysical Union, 2013)The sources and distribution of organic matter (OM) in surface sediments of the eastern continental margin of India, including the region influenced by river discharge, were investigated using content, molar C:N ratios and ... -
Estuaries of India: Making amends in a changing world
(ENVIS publisher, 2013)This short write up descibes the importance of estuarine ecosystems and the need to save it from the ill effects of anthropogenic factors. The issues like pollution caused by chemicals and overfishing are discussed in brief.
