Coastal placer minerals
(NISCAIR Publications, 2014)India is blessed with a long coastline of more than 7500 km, including islands. The erosion of rocks results in coastal placer minerals, which find many applications. -
The NOW regional coupled model: Application to the tropical Indian Ocean climate and tropical cyclone activity
(American Geophysical Union, 2014)This paper presents the NOW regional coupled ocean-atmosphere model built from the NEMO ocean and WRF atmospheric numerical models. This model is applied to the tropical Indian Ocean, with the oceanic and atmospheric ... -
Oxygen isotopic analyses of individual planktic foraminifera species: Implications for seasonality in the western Arabian Sea
(Copernicus Publications, 2014)The variation of stable isotopes between individual shells of planktic foraminifera of a given species and size may provide short-term seasonal insight on Paleoceanography. In this context, oxygen isotope analyses of ... -
Geologic implications of gas hydrates in the offshore of India: Results of the National Gas Hydrate Program Expedition 01
(Elsevier, 2014)The Indian National Gas Hydrate Program Expedition 01 (NGHP-01) is designed to study the occurrence of gas hydrate along the passive continental margin of the Indian Peninsula and in the Andaman convergent margin, with ... -
Guidance on Port Biological Baseline Surveys (PBBS)
(GEF-UNDP-IMO GloBallast Partnerships, IOI, NIO, IUCN, 2014)This publication has been prepared by GBP, IOI, CSIR-NIO and IUCN in order to serve as guidance to those who are planning to carry out a port biological baseline survey, in particular in the context of Ballast Water ... -
Atmospheric fine and coarse mode aerosols at different environments of India and the Bay of Bengal during winter-2014: Implications of a coordinated campaign
(Metrology Society of India, 2014)In this paper, we present mass concentrations of particulate matter [PM<sub>2.5</sub>, PM<sub>10</sub> size fractions and total suspended particulates (TSP)] measured simultaneously over land stations (Kullu, Patiala, ... -
A medieval port at Ghogha in the Gulf of Khambhat, west coast of India
(Swati Publications, 2015)The Gulf of Khambhat has been a focal area for the human settlements since the Harappan and it is also famous for the highest tidal range in India. The author of the Periplus of the Erythrenean Sea vividly described the ... -
Stone anchors from Mombasa, Kenya: Evidence of maritime contacts with Indian Ocean countries
(Australasian Institute for Maritime Archaeology, 2015)For 2000 years or more, the East African Coast has had contacts with other parts of the world and that was possible because an understanding of the monsoon winds and current patterns of the region encouraged the interchange ... -
Effect of monsoonal perturbations on the occurrence of phytoplankton blooms in a tropical bay
(Inter-Research, 2015)In this study, the influence of intraseasonal variations in rainfall and the resultant freshwater flux (monsoon perturbations) on phytoplankton bloom dynamics were evaluated by quantifying live phytoplankton at a fixed ... -
Spatial distribution of sound channel and its parameters in north Indian ocean
(David Publishing, 2015)The Present work reports the variability of the derived sound channel and its parameters (surface sound velocity, conjugate depth, SLD (Sonic Layer depth) and SOFAR(Sound Fixing and Ranging) depth) has been presented over ... -
Surfzone wave characteristics during flood tide on the central west coast of India
(World Scientific Publishing, 2015)Surfzone wave characteristics, measured using a wave and tide gauge (WTG) during a flood tide, were studied at three different beaches having different nearshore slopes. The spectral wave characteristics viz., wave-height ... -
Range-based underwater vehicle localization in the presence of unknown ocean currents: Theory and experiments
(IEEE, 2016)This paper addresses the problem of range-based autonomous underwater vehicle (AUV) localization in the presence of unknown ocean currents. In the setup adopted, the AUV is equipped with an attitude and heading reference ... -
Changes in nearshore waves during the active sea/land breeze period off Vengurla, central west coast of India
(Copernicus Publications, 2016)A unique feature observed in the tropical and subtropical coastal area is the diurnal sea-breeze/land-breeze cycle. We examined the nearshore waves at 5 and 15 m water depth during the active sea/land breeze period ... -
Significance of investigating allelopathic interactions of marine organisms in the discovery and development of cytotoxic compounds
(Elsevier, 2016)Marine sessile organisms often inhabit rocky substrata, which are crowded by other sessile organisms. They acquire living space via growth interactions and/or by allelopathy. They are known to secrete toxic compounds having ... -
Kinetic speciation of mercury–humate complexes in aqueous solutions by using competing ligand exchange method
(Elsevier, 2016)Competing ligand exchange method (CLEM) in conjunction with direct mercury analyzer (DMA) was found to be a useful method for kinetic speciation study of (mercury–humic acid) Hg–HA complexes in aqueous systems. Ambersep ... -
A reduction in marine primary productivity driven by rapid warming over the tropical Indian Ocean
(American Geophysical Union, 2016)Among the tropical oceans, the western Indian Ocean hosts one of the largest concentrations of marine phytoplankton blooms in summer. Interestingly, this is also the region with the largest warming trend in sea surface ... -
A traditional boats and navigational history of Odisha, East coast of India
(Indian Society for Prehistoric and Quaternary Studies, 2015)It is Believed that around 60,000 yrs. ago when the sea level was lower people employed floats or rafts for water crossing. Over the centuries, different types of traditional boats were constructed and used for maritime ... -
Sediment pathways and emergence of Himalayan source material in the Bay of Bengal
(Current Science Association, 2016)The sediment succession in the Bay of Bengal (BoB) records the signatures corresponding to India–Asia collision, regional climate change, and erosional proc- esses of both the Himalayan orogen and Indian subcontinent. The ... -
