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 ... -
Characteristics of long-period swells measured in the near shore regions of eastern Arabian Sea
(Elsevier, 2016)Measured wave data covering two years simultaneously at 3 locations along the eastern Arabian Sea reveals the presence of long-period (peak wave period > 18 s) low-amplitude waves (significant wave height < 1 m) and the ... -
Impact of accidental leakage of furnace oil on Mahul creek mangrove vegetation
(NISCAIR Publications, 2016)A pipeline carrying furnace/black oil from Butcher Island to the petrochemical complex at Mahul in Mumbai started leaking during 3rdweek of October 2013 and went unnoticed till first week of November 2013. The alignment ... -
Influence of 2015 flood on the distribution and occurrence of microplastic pellets along the Chennai coast, India
(Elsevier, 2016)The sources, distribution, surface features, polymer composition and age of microplastic pellets (MPPs) in surface sediments along the Chennai coast during March 2015 (pre-Chennai flood) and November 2015 (post-Chennai ... -
Geospatial approach towards enumerative analysis of suspended sediment concentration for Ganges-Brahmaputra Bay
(Elsevier, 2016)This study presents an easy, modular, user-friendly, and flexible software package for processing of Landsat 7 ETM and Landsat 8 OLI-TIRS data for estimating suspended particulate matter concentrations in the coastal waters. ... -
The abrupt onset of the modern South Asian monsoon winds
(Macmillan Publishers Limited, 2016)The South Asian Monson (SAM) is one of the most intense climatic elements yet its initiation and variations are not well established. Dating the deposits of SAM wind-driven currents in IODP cores from the Maldives yields ... -
Community structure and coral health status across the depth gradients of Grande Island, Central west coast of India
(Elsevier, 2016)The Grande Island, located at the central west coast of India is one of the less studied coral reef systems in India. In this study, we provide a comprehensive description of the coral community structure and health status ... -

(Bombay Natural History Society, 2011)Recolonization of benthos following dredging operations was studied in Mormugao Port Trust Harbour, Goa Six stations were fixed for sampling within the radius of the dredging site Three samples each were collected during ... -
Antimicrobial activity of Serratia sp isolated from the coralline red algae Amphiroa anceps
(CSIR-NISCAIR, 2015)Bacterial isolates (6 nos) were obtained from the coralline red algae Amphiroa anceps Crude extract of these isolated were tested for antimicrobial activity against 20 different human pathogenic bacterial and fungal strains ... -
Morphological characteristics of bioaerosols from contrasting locations in southern tropical India - A case study
(Elsevier, 2015)Bioaerosols, which are ubiquitous in the earth`s atmosphere, are poorly characterized in terms of their physical and chemical properties Improved knowledge of their physical and chemical properties is essential to have a ... -
