Pathogenic multiple antimicrobial resistant Escherichia coli serotypes in recreational waters of Mumbai, India: A potential public health risk
(Springer, 2017)Globally, coastal waters have emerged into a pool of antibiotic resistance genes and multiple antibiotic resistant microorganisms, and pathogenicity of these resistant microorganisms in terms of serotypes and virulence ... -
Alkaline phosphatase: An appraisal of its critical role in c-limited deep-sea sediments of central Indian Basin
(Taylor & Francis Group, 2017)Alkaline phosphatase (ALP) is a hydrolase that releases phosphate, a crucial nutrient supporting formation of many macromolecules. The oligotrophic sediments of Central Indian Basin (CIB) were examined for the extent of ... -
Development of environmental management plan for deep-sea mining
(Springer, 2017)Deep-sea mining is currently at a stage when several mine sites have been identified, mining technologies are under development, processing technologies are being tested, studies for assessing potential environmental impacts ... -
Assessment of distribution characteristics of polymetallic nodules and their implications on deep-sea mining
(Springer, 2017)This chapter looks at the distribution characteristics of nodules and associated seafloor features so as to provide this information to the industry for designing a suitable mining system. Further, it also looks at different ... -
Deep-sea mining: Current status and future considerations
(Springer, 2017)Deep-sea minerals such as polymetallic nodule, hydrothermal sulphides, and ferro-manganese crusts have for long attracted attention as an alternative source of metals to terrestrial deposits. The occurrence of many of these ... -
Longshore sediment transport in the surf zone based on different formulae: A case study along the central west coast of India
(Springer, 2017)Understanding longshore sediment transport (LST) is a prerequisite for designing an effective coastal zone management strategy. The present study estimates the LST along the central west coast of India based on four bulk ... -
Suspended sediment dynamics in Cochin estuary, West coast, India
(Springer, 2017)An observational study was conducted in Cochin estuary to examine the relative impacts of tidal and river runoff forcing upon suspended sediment dynamics at different time scales. Time series measurements of salinity and ... -
Benthic dinoflagellate blooms in tropical intertidal rock pools: Elucidation of photoprotection mechanisms
(Springer, 2017)Intertidal rockpools (RPs), forming a ubiquitous component of rocky shores, are biologically rich ecosystems influenced by short-term (hours-days) and long-term (days-seasons) fluctuating environments. So far, studies on ... -
Understanding heavy mineral dynamics using magnetic fingerprinting technique: A case study of North Maharashtra Coast, India
(Springer, 2017)Environmental magnetic and grain size measurements were carried out on sand samples collected from nine sand pits along a 20-km coastal stretch of Arnala Beach, North Maharashtra, India. This study sets out to identify the ... -
Diversity of bacteria and fungi associated with tarballs: Recent developments and future prospects
(Elsevier, 2017)Tarballs are formed by weathering of crude oil in marine environment. They are transported from open ocean to the shores by sea currents and waves. Tarball pollution is a major concern to global marine ecosystem. Microbes ... -
Discriminating the biophysical impacts of coastal upwelling and mud banks along the southwest coast of India
(Elsevier, 2017)Coastal upwelling and mud banks are two oceanographic processes concurrently operating along certain stretches of the southwest (Kerala) coast of India during the Southwest Monsoon period (June-September), facilitating ... -
Mercury exposure and Alzheimer's disease in India: An imminent threat?
(Elsevier, 2017)India is an industrial giant with one of the fastest growing major economies in the world. Primary energy consumption in India is third after China and the USA. Greater energy production brings the burden of increasing ... -
Effect of physico-chemical regimes and tropical cyclones on seasonal distribution of chlorophyll-a in the Chilika Lagoon, east coast of India
(Springer, 2017)A comprehensive analysis on spatiotemporal variation in physico-chemical variables and their control on chlorophyll-a during 2013-14 was carried out in the Chilika Lagoon. Spatiotemporal variation in physico-chemical regimes ... -
Seasonal distribution of phytoplankton and its association with physico-chemical parameters in coastal waters of Malvan, west coast of India
(Springer, 2017)Malvan coast is one of the Marine Protected Area (MPA) of Maharashtra because of its rich coral reef and biodiversity. The study investigated on phytoplankton assemblage and their diversity with respect to physico-chemical ... -
Differential response of coral communities to Caulerpa spp. bloom in the reefs of Indian Ocean
(Springer, 2017)Coral reef ecosystems are disturbed in tandem by climatic and anthropogenic stressors. A number of factors act synergistically to reduce the live coral cover and threaten the existence of reefs. Continuous monitoring of ... -
Changes in depositional environment for the past 35 years in the Thane Creek, central west coast of India: Inferences from REEs, metals and magnetic properties
(Springer, 2017)The role of diagenetic processes in influencing the behaviour of metals (Fe, Mn, Cu, Ni, Zn), rare earth elements (REEs) and environmental magnetic parameters in two sediment cores from a polluted creek environment (the ... -
Bacterial activity in hydrogenetic ferromanganese crust from the Indian Ocean: A combined geochemical, experimental and pyrosequencing study
(Springer, 2017)The Afanasiy-Nikitin Seamount (ANS) in the Equatorial Indian Ocean harbors hydrogenetic ferromanganese (Fe-Mn) crusts. It was hypothesized that the bacteria associated with the crust catalyze the precipitation of metal ... -
Synthesis of stable nanosilver particles (AgNPs) by the proteins of seagrass Syringodium isoetifolium and its biomedicinal properties
(Elsevier, 2016)A simple eco-friendly approach for the hasty synthesis of stable, potent and benign silver nanoparticles (AgNPs) using seagrass, Syringodium isoetifolium was proposed and described here. The UV–Vis, DLS, XRD, AFM, FESEM, ... -
Detection of decadal shoreline changes along Dhamara and Maipura coast, Odisha, India
(IAHR-AIRH, 2014)Coastal erosion is one of the major problems of the coastal zone. The erosion is triggered by various reasons such as high wave energy, reduction of sediments, natural disasters and climate change etc. In the era of ... -
Seasonal dynamics of adjoining tidal coastal inlet on east coast of India measurements and modelling
(IAHR-AIRH, 2014)The opening and closure of coastal tidal inlets play a major role in regulating the water and sediment exchange between the river and ocean as well as in the interruption of the longshore sediment transport. The present ...
