Spatial variability in phytoplankton community structure along the eastern Arabian Sea during the onset of south-west monsoon
(Elsevier, 2016)The Arabian Sea experiences moderate to weak upwelling along the south-west coast of India, which subsequently propagates towards the north. This causes variation in plankton community composition, which is addressed in ... -
Reevaluation of design waves off the western Indian coast considering climate change
(Marine Technology Society, 2016)Knowledge of design waves with long return periods forms an essential input to many engineering applications, including structural design and analysis. Such extreme or long-term waves are conventionally evaluated using ... -
Indian Ocean dipole modulated wave climate of eastern Arabian Sea
(European Geosciences Union, 2016)Intrinsic modes of variability have a significant role in driving the climatic oscillations in the oceanic processes. In this paper, we investigate the influence of an inter-annual mode of variability, the Indian Ocean ... -
South Asian summer monsoon variability during the last ~54 kyrs inferred from surface water salinity and river run off proxies
(Elsevier, 2016)The past variability of the South Asian Monsoon is mostly known from records of wind strength over the Arabian Sea while high-resolution paleorecords from regions of strong monsoon precipitation are still lacking. Here, ... -
Why is the Bay of Bengal experiencing a reduced rate of sea surface warming?
(Royal Meteorological Society, 2016)The sea surface temperature (SST) in the Bay of Bengal (BoB) during the period 1960–1995 showed a decadal cycle, riding over a warming trend. The disruption of the decadal cycle was noticed post-1995 and was followed by a ... -
Large-scale bioprospecting of cyanobacteria, micro- and macroalgae from the Aegean Sea
(Elsevier, 2016)Marine organisms constitute approximately one-half of the total global biodiversity, being rich reservoirs of structurally diverse biofunctional components. The potential of cyanobacteria, micro- and macroalgae as sources ... -
Mud banks of Kerala: Mystery yet to be unveiled!
(CSIR-NISCAIR, 2016)Mud Banks are areas of the sea adjoining the coast with calm water during the roughest monsoon conditions of the sea. They provide a rich catch of fishery too. -
Coupled C-S-Fe geochemistry in a rapidly accumulating marine sedimentary system: Diagenetic and depositional implications
(Wiley, 2015)In the present study, we have investigated the C-S-Fe systematics in a sediment core (MD161-13) from the Krishna-Godavari (K-G) basin, Bay of Bengal he core covers the late Holocene period with high overall sedimentation ... -
Can hydrocarbons in coastal sediments be related to terrestrial flux? A case study of Godavari river discharge (Bay of Bengal)
(Current Science Association, 2015)A sediment core aged ~250 years and deposition rate of ~2.4 mm yr<sup>-1</sup> raised from the coastal region receiving inputs from the Godavari river was examined for n-alkanes The carbon preference index (CPI) of shortchain ... -
CSIR-National Institute of Oceanography
(Indian Academy of Sciences, Bangalore, 2012)CSIR-National Institute of Oceanography being one of its kind in the country The article describes the on-going researches and projects in contributing to the science in the field of Marine science. -
Storm and tsunami induced sediment transport and morphology changes in vicinity of tidal inlets
(Indian Institute of Technology, Madras, 2014)This study comprises of numerical modelling studies on the morphology changes in the vicinity of tidal inlets. Two real case scenarios comprising of a very severe cyclonic storm and the mega Indian Ocean tsunami were ... -
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 ... -

(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
