Metabolism of DMSP, DMS and DMSO by the cultivable bacterial community associated with the DMSP-producing dinoflagellate Scrippsiella trochoidea
(Springer, 2012)Bacterial species associated with the dimethylsulfoniopropionate (DMSP)-producing phytoplankton Scrippsiella trochoidea were cultured and identified, with the aim of establishing their ability to metabolise DMSP, dimethylsulfide ... -
Production of dimethylsulphide during the seasonal anoxia off Goa
(Springer, 2012)Subsurface waters over the western Indian continental shelf experience seasonal anoxia towards the end of the southwest monsoon season. During a 3-day study carried out at the Candolim time series site (off the coast of ... -
SEM–EDS analysis of copper, glass and iron recovered from the 1st century AD shipwreck site off Godawaya, Southern Sri Lanka
(Current Science Association, 2012)Recent maritime archaeological explorations conducted at a shipwreck site in the offshore regions of Godawaya, a fishing village on the south coast of Sri Lanka led to the retrieval of several artifacts such as copper slag, ... -
Seabed habitat mapping employing single and multi-beam backscatter data: A case study from the western continental shelf of India
(Elsevier, 2012)Acoustic backscatter from multi-beam echo-sounder (MBES) and dual-frequency single-beam echo-sounding systems (SBES) operable at 95 kHz and 33/210 kHz, respectively, were used to study the distribution of sediment texture ... -
Coastal circulation along the central west coast of India during cyclone Phyan: measurements and numerical simulations
(Springer, 2012)Measurements and numerical simulations carried out off Mumbai coast for the period 22 October to 22 November 2009 showed significant variations in water level and currents during cyclone Phyan. Changes in the meridional ... -
Compositional variation recorded in deep-sea ferromanganese deposits of the Central Indian Ocean
(Current Science Association, 2012)Traditionally, the genesis of marine ferromanganese deposits (abyssal nodules and seamount crusts) has been discussed mostly based on their bulk composition. But, marine ferromanganese deposits are products of an intimate ... -
Direct bed stress measurements under solitary tsunami-type waves and breaking tsunami wave fronts
(World Scientific Pub. Co., 2009)During their propagation tsunamis often traverse continental slopes that are relatively steep compared to deeper oceans. Further due to the change of bed slope from offshore to near shore, there is every likely possibility ... -
Indian monsoon variability at different time scales: Marine and terrestrial proxy records
(Indian National Science Academy, 2012)Here, we present a review of the work done in India during 2007-2011 on various proxy records of monsoon variability preserved in the marine (Central Indian Basin, western, northern and eastern Arabian Sea and the Bay of ... -
Geo-scientific investigations of gas-hydrates in India
(Indian National Science Academy, 2012)The best solution to meet India's overwhelming energy requirement is to tap the nuclear and solar power to the maximum extent possible. Another feasible major energy resource is gas-hydrates (crystalline substances of ... -
Coastal vulnerability assessment for Chennai, east coast of India using geospatial techniques
(Springer, 2012)The 56-km coastal zone of Chennai district of the Tamil Nadu state, southeast coast of India, which includes tourist resorts, ports, hotels, fishing villages, and towns, has experienced threats from many disasters such as ... -
The role of salinity on the dynamics of the Arabian Sea mini warm pool
(American Geophysical Union, 2012)Warmer (more than 28 degrees C) sea surface temperature (SST) occurs in the South Eastern Arabian Sea (SEAS, 5 degrees N-13 degrees N, 65 degrees E-76 degrees during March-April, and is known as the Arabian Sea Mini Warm ... -
Statistical analysis on extreme wave height
(Springer, 2012)The classical extreme value theory based on generalized extreme value (GEV) distribution and generalized Pareto distribution (GPD) is applied to the wave height estimate based on wave hindcast data covering a period of 31 ... -
Indian contributions in the field of palaeoceanography (2006-2012)
(Indian National Science Academy, 2012)Excellent studies have been carried by Indian scientists to understand paleoceanographic changes in the Indian Ocean including the Arabian Sea and Bay of Bengal using Ocean Drilling Program cores. These studies revealed ... -
Statistical prediction of Late Miocene climate
(National Institute of Oceanography (CSIR), India, 1994)The theory of statistical prediction of paleoclimate (Imbrie and Kipp, 1971), which includes multiple regression analysis and factor analysis is reviewed. Necessary software is listed. An application to predicting palaeo ... -
Time Series Observations in the North Indian Ocean
(IMBER, 2011)Unlike the Atlantic and the Pacific Ocean, the northern Indian Ocean is geographically unique. The bounding to the north by the Asian landmass has a profound impact on the biogeochemistry of the region. The Arabian Sea ... -
Study of Modis satellite derived aerosol angstrom exponent and in-situ measured values using Sun photometer in part of the west coast of Indian Peninsula
(Indian Society of Geomatics, 2011)The aerosol angstrom exponent (AAE) is often used as a qualitative indicator of aerosol particle size. It is important to understand and quantify the microphysical impact of aerosols which are derived from natural and ... -
Study of Chinese porcelain sherds of Old Goa, India: Indicators of trade contacts
(Journal of the Indian Society for Prehistoric and Quarternary Studies, 2011)Chinese ceramics have a long history of evolution and distribution. Chinese ceramics have been discovered from habitations, ports, trade centres and shipwrecks sites which facilitated the precise dating of sites and ... -
Vibrio harveyi modulated gene expression in Penaeus monodon and Fenneropenaeus indicus
