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 ... -
High resolution Holocene paleomagnetic secular variation records from Bay of Bengal
(Elsevier, 2016)We present high resolution paleosecular variation (PSV) records up to 8 cal. kyr BP from three piston cores, MD161/8, MD161/11 and MD161/13 acquired in the Krishna-Godavari (KG) basin, Bay of Bengal. During the Holocene ... -
Distribution of multiple antibiotic resistant Vibrio spp across Palk Bay
(Elsevier, 2016)Presence of multiple antibiotic resistant microorganisms in marine systems is increasingly a focus of concern as they pose potential health risk to humans and animals. The present study reports the distribution, diversity, ... -
Comparison of long-term variability of sea surface temperature in the Arabian Sea and Bay of Bengal
(Elsevier, 2016)Long-term variability of Sea Surface Temperature (SST) in the Arabian Sea (AS) and Bay of Bengal (BoB) during 1880–2010 is examined using all the available data sets of monthly SST, wind speed, incoming solar radiation, ... -
δ<sup>18</sup>O and salinity variability from the last glacial maximum to recent in the Bay of Bengal and Andaman Sea
(Elsevier, 2016)Oxygen isotopes of surface, thermocline and bottom dwelling foraminifera were analysed from two well-dated Andaman Sea cores and combined with nine previously published records from the Bay of Bengal (BoB) and Andaman Sea ... -
Influence of spatial competitor on the growth and regeneration of the marine sponge Cinachyrella cf. cavernosa (Porifera, demospongiae)
(Springer, 2016)Availability of suitable substratum is often a limiting factor for sessile organisms. We studied growth and regeneration of golf ball sponge Cinachyrella cf. cavernosa with and without its aggressive neighbour, soft coral ... -
Partitioning of metals in different binding phases of tropical estuarine sediments: importance of metal chemistry
(Springer, 2016)Distribution of metals in different binding phases of estuarine sediments provides chemically significant description of metal–sediment interactions. This study describes the influences of ligand field stabilization energy ... -
Estimating discharge from the Godavari river using ENVISAT, Jason-2, and SARAL/AltiKa radar altimeters
(Taylor & Francis, 2016)The present work discusses the application of radar altimeters on-board Environmental Satellite (ENVISAT), Jason-2, and Satellite with Argos and AltiKa (SARAL) missions to estimate the Godavari River discharge draining ... -
Structure and function of nematode communities across the Indian western continental margin and its oxygen minimum zone
(Copernicus Publications, 2016)We studied patterns of nematode distribution along the western Indian continental margin to determine the influence of habitat heterogeneity and low oxygen levels on the community’s taxonomic and functional structure. A ... -
