Monsoonal effects on beach and offshore sediments from kalbadevi bay, Ratnagiri, Maharashtra state, India.
(DAV publisher, 2014)Sediment samples representing the beach and offshore area of Kalbadevi Bay, Ratnagiri, Maharashtra were studied for different seasons along three east-west beach profiles (BP-01, BP-02 and BP-03) which covered berm, dune, ... -
The Myanmar continental shelf
(The Geological Society of London, 2014)The Myanmar (Burma) coastline is about 2280 km long, with the continental shelf covering an area of approximately 230 000 km<SUP>2</SUP>. The Myanmar coastline may be divided into the northern Rakhine (Arakan) coast, the ... -
Late holocene primary productivity and sea surface temperature variations in the northeastern Arabian Sea: Implications for winter monsoon variability.
(American Geophysical Union, 2014)Variability in the oceanic environment of the Arabian Sea region is strongly influenced by the seasonal monsoon cycle of alternating wind directions. Prominent and well studied is the summer monsoon, but much less is known ... -
GPR studies over the tsunami affected Karaikal beach, Tamil Nadu, south India.
(Indian Academy of Sciences, 2014)In this study, results of GPR profiling related to mapping of subsurface sedimentary layers at tsunami affected Karaikal beach are presented . A 400 MHz antenna was used for profiling along 262 m stretch of transect from ... -
An appraisal of an iterative construction of the endmembers controlling the composition of deep-sea manganese nodules from the Central Indian Ocean Basin.
(Indian Academy of Sciences, 2014)This paper describes an estimation of endmember compositions followed by the assessment of those results by log-ratio variance analysis. As an appraisal, it deals only with the first objective of an endmember analysis ... -
Observed seasonal and intraseasonal variability of the East India Coastal Current on the continental slope.
(Indian Academy of Sciences, 2014)We present data from three acoustic Doppler current profilers (ADCPs) moored off Cuddalore (12 Degree N), Kakinada (16.5 Degree N), and Gopalpur (19 Degree N) on the continental slope of the western Bay of Bengal and one ... -
Interplay of diverse environmental settings and their influence on the plankton community off Myanmar during the spring intermonsoon.
(Elsevier, 2014)The northern Andaman Sea including the Myanmar waters is one of the least studied regions of the northern Indian Ocean. The freshwater and suspended sediments carried by Ayeyawady/Irrawaddy, the peculiar surface circulation, ... -
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
