The final spawning ground of Tachypleus gigas (Muller, 1785) on the east Peninsular Malaysia is at risk: A call for action.
(PeerJ, Inc, 2016)Tanjung Selongor and Pantai Balok (State Pahang) are the only two places known for spawning activity of the Malaysian horseshoe crab - Tachypleus gigas (Muller, 1785) on the east coast of Peninsular Malaysia. While the ... -
Indian contributions in the field of marine micropaleontology (2010-2015)
(Indian National Science Academy, 2016)An overview of the research contributions made during the last five years by the Indian scientists in the field of marine micropaleontology is presented. Large scale micropaleontological studies employing assemblages of ... -
Mass mortality of macrobenthos in a biodiverse rocky beach- Impact of a minor oil spill
(NISCAIR, CSIR, 2016)A field survey was carried immediately post an accidental oil spill at rocky intertidal zone of Uran. Mass mortality of macrobenthos was observed at spillage site whereas reference site harboured diverse and live macrobenthic ... -
Advances in marine geophysical studies of the Indian Ocean: Contributions from India (2010-2015)
(Indian National Science Academy, 2016)Indian scientists carrying marine geophysical research at different Earth Science institutions have made significant advances during the last six years (2012-2015) for understanding evolution of continental margins of India ... -
Unicellular cyanobacteria synechocystis accommodate heterotrophic bacteria with varied enzymatic and metal resistance properties
(WILEY-VCH Verlag GmbH & Co., 2016)The interactions between heterotrophic bacteria and primary producers have a profound impact on the functioning of marine ecosystem. We characterized the enzymatic and metal resistance properties of fourteen heterotrophic ... -
The tectonic origin of the Bay of Bengal and Bangladesh
(American Geophysical Union Publications, 2016)We are able to decipher the tectonic evolution of the Bay of Bengal, a puzzle which has not been satisfactorily solved in the past, and we are also able to shed new light on origin of the buried 85°E Ridge. We do so by ... -
Extraterrestrial components from deep sea sediments of Indian Ocean
(Indian National Science Academy, 2016)Two different types of extraterrestrial particulate matter collections were undertaken during the last few years-by using magnets encased in dredges that were dragged along the seafloor and by sieving massive quantities ... -
Inhibition of mixed-layer deepening during winter in the northeastern Arabian Sea by the West India coastal current
(Springer, 2016)Though the deep mixed layers (MLs) that form in the northeastern Arabian Sea (NEAS) during the winter monsoon (November–February) have been attributed to convective mixing driven by dry, cool northeasterly winds from the ... -
Exploration of shipwreck off Konark coast, Odisha- A preliminary study
(Indian Society for Prehistoric and Quaternary Studies, 2016)Archaeological findings suggest that ports of Odisha were well connected with other ports of the Indian subcontinent and Persian Gulf, Red Sea and Southeast Asian countries. In the course of maritime trade, many vessels ... -
Effects of bottom water oxygen concentrations on mercury distribution and speciation in sediments below the oxygen minimum zone of the Arabian Sea
(Elsevier, 2016)This study investigated the influences of varying dissolved oxygen (DO) levels in overlying bottom water, sediment grain size, total sedimentary organic carbon (C<sub>org</sub>), and total sedimentary sulfide concentrations ... -
Denitrification activity in mangrove sediments varies with associated vegetation
(Elsevier, 2016)To test the hypothesis that mangrove vegetation associated sediment characteristics could influence an ecologically important function such as denitrification, a study was carried out at the Divar mangrove ecosystem in ... -
Slow spreading ridges of the Indian Ocean: An overview of marine geophysical investigations
(Indian Geophysical Union, 2016)Sparse and non-availability of high resolution geophysical data hindered the delineation of accurate morphology, structural configuration, tectonism and spreading history of Carlsberg Ridge (CR) and Central Indian Ridges ... -
Integrated geophysical study off Goa, Central West Coast of India
(Indian Geophysical Union, 2016)The western Indian offshore is characterized by several tectonic elements along its entire length. The prominent ones include the Laxmi Ridge (LR) and the Chagos-Laccadive Ridge (CLR) in the north and south, respectively. ... -
Estuarine and marine geology (2011-2015)
(Proceedings of the Indian National Science Academy, 2016)The estuaries of the Mandovi and Zuari (Ma-Zu) Rivers and Godavari River have been investigated extensively for understanding the sedimentary and bio-geochemical processes during the last 5 years. Estuarine turbidity maximum ... -
Waning of plankton food web in the upstream region of the Cochin backwaters during the southwest monsoon
(CSIR-NISCAIR, 2015)Heterotrophic bacteria (0.2-2 µm), pico-phytoplankton (0.2-2 µm), nano-phytoplankton (2-20 µm), micro-phytoplankton (>20 µm), heterotrophic nanoflagellates (2-20 µm), and micro-zooplankton (20- 200 µm) present in the Cochin ... -
Diversity and distribution of phytoplankton at Verem(Mandovi estuary) Goa
(Goa: Goa University, 2015)To understand diversity, distribution and the effect of environmental factors on phytoplankton, samples were collected fortnightly at Verem station in the Mandovi estuary during monsoon and non-monsoon period from June ... -
Evaluation of surface water and sediment quality in Chicalim Bay, Nerul Creek, and Chapora Bay from Goa coast, India - a statistical approach
(Springer, 2016)To better understand the spatial and temporal variation in surface water and sediment quality, parameters were evaluated from the three sites Chicalim Bay (CB), Nerul Creek (NC), and Chapora Bay (ChB) along the Goa coast, ... -
Microbial and biochemical alterations due to storage of deep-sea sediments under ambient tropical conditions
(NISCAIR Publications, 2016)Response of indigenous bacteria to incubation at normal pressure and tropical temperature (28 ± 2°C), were examined in four deep-sea sediments from polymetallic-nodule fields in Central Indian Basin (CIB). Sediments were ... -
