Changes in the coastal and marine environments
(Capital Publishing Co., 2010)The environmental setting and possible influence of global environmental change, including that of climate change, have been presented for coastal and marine environments of South Asia. This has been dealt with in seven ... -
Physical oceanography

Detection of DNA damage in fish Oreochromis mossambicus induced by co-exposure to phenanthrene and nitrite by ESI-MS/MS
(Springer-Verlag, 2010)Mutagenic nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) have been known to arise in the environment through direct emissions from combustion sources and nitration of PAHs, primarily in the atmosphere. In the marine ... -
Studies on the sediments of Vembanad Lake, Kerala state Part III Distribution and interpretation of bottom sediments
(CSIR-NISCAIR, 1974)Distribution patterns of FE, Mn, Ti, Ni, Co and Cu in sediments of Vembanad Lake and adjoining river systems have revealed that (1) elemental concentrations follow closely the texture of the sediments, (2) river sands ... -
Fungal diversity in oxygen-depleted regions of the Arabian Sea revealed by targeted environmental sequencing combined with cultivation
(Blackwell Publishing, 2010)In order to study fungal diversity in oxygen minimum zones of the Arabian Sea, we analyzed 1440 cloned small subunit rRNA gene (18S rRNA gene) sequences obtained from environmental samples using three different PCR primer ... -
Indian Ocean margins
(Springer-Verlag, 2010)The most important biogeochemical transformations and boundary exchanges in the Indian Ocean seem to occur in the northern region, where the processes originating at the land-ocean boundary extend far beyond the continental ... -
Carbon and nitrogen fluxes in the North Indian Ocean
(Springer-Verlag, 2010)The land mass that blocks the Indian Ocean in the north at low latitudes profoundly influences the climate, circulation and biogeochemical processes of its northern basins. The asymmetrical distribution of freshwater and ... -
Geochemical characterization of oceanic basalts using artificial neural network
(BioMed Central Ltd, 2009)The geochemical discriminate diagrams help to distinguish the volcanics recovered from different tectonic settings but these diagrams tend to group the ocean floor basalts (OFB) under one class i.e., as mid-oceanic ridge ... -
The nature and distribution of particulate matter in the Mandovi Estuary, central west coast of India
(Coastal and Estuarine Research Federation, 2010)Systematic seasonal variations of suspended particulate matter (SPM) along a 44-km transect of the Mandovi estuary reveal that the concentrations of SPM are low at river-end stations, increase generally seaward, and are ... -
Dynamics of formation of ferromanganese nodules in the Indian Ocean
(Elsevier, 2010)The ferromanganese nodule resources of the Indian Ocean Nodule Field (IONF) are second only in the world in terms of metal content and abundance. Since it was made known by Mero (1965) that several trillion tonnes of ... -
Hydrography and biogeochemistry of the coastal ocean
(American Geophysical Union, 2009)The coastal ocean accounts for only 7% of the total oceanic area, but it plays a very important role in biogeochemical cycles. It not only exchanges energy and matter with the open ocean, but terrestrial inputs of materials ... -
The next generation of iron fertilization experiments in the southern Ocean
(Cambridge University Press, 2010)Of the various macro-engineering schemes proposed to mitigate global warming, ocean iron fertilization (OIF) is one that could be started at short notice on relevant scales. It is based on the reasoning that adding trace ... -
Ocean wave prediction using numerical and neural network models
(Bentham Open, 2010)This paper presents an overview of the development of the numerical wave prediction models and recently used neural networks for ocean wave hindcasting and forecasting. The numerical wave models express the physical concepts ... -
Geochemical characterisation of major and trace elements in the coastal sediments of India
(Springer, 2010)Thirty-five surface sediment samples from the Indian continental shelf were recovered offshore from the mouths of the major rivers (Brahmaputra, Ganges, Narmada, Tapti, Godavari, Krishna and Cauvery) discharging into the ... -
Study of cadmium-humic interactions and determination of stability constants of cadmium-humate complexes from their diffusion coefficients obtained by scanned stripping voltammetry and dynamic light scattering techniques
(Elsevier, 2010)Diffusion coefficients of Cd–humate complexes are dependent on pH and [Cd]/[Humic] Acid (HA)] ratio in a Cd-HA system. These two factors mainly control the mass transport and complexation kinetics of Cd that may influence ... -
A baseline study of trace metals in a coral reef sedimentary environment, Lakshadweep Archipelago
(Springer, 2010)Surficial and core samples collected from the sedimentary microenvironments of Lakshadweep Archipelago were analysed for their trace metal contents. The synoptical relations in spatial distributions with respect to ... -
Impact of bottom trawling on sediment characteristics - A study along inshore waters off Veraval coast, India
(Springer, 2010)The present communication is a study on the impact of bottom trawling on the sediment characteristics along Veraval coast, which is the largest trawler port of India. Experimental bottom trawling was conducted from MFV ... -
A note on Ruppia species (Ruppiaceae) from the abandoned saltpan in the Gulf of Kutch, India
(NISCAIR, CSIR, 2009)Ruppia bed measuring approx. 0.015 km sup(2) was observed from the shallow waters in the saltpan. The salinity and temperature of the overlying waters of the bed was 22.7 PSU and 30 degrees C, respectively. Vegetative ... -
Utilization of high resolution satellite geoid data for estimation of lithospheric thickness in the Bay of Bengal
(NISCAIR, CSIR, 2009)Very high-resolution database generated from Seasat, Geosat GM, ERS-1 and TOPEX/ POSEIDON altimeters data of the northern Indian Ocean has been used for the first time for preparation of geoid and free-air gravity maps. ... -
Tsunami induced transportation of the coastal marine sediments to distant onshore regions: Some indications from foraminiferal and microbenthic studies of new Wandoor region (Andaman & Nicobar)
(Disaster Advances, 2009)The foraminiferal and microbenthos studies were carried out on samples collected from onshore soils/sediments from cultivated fields. The presence of exclusive marine organisms namely foraminifera in the soil of cultivated ...
