Noctiluca and copepods grazing on the phytoplankton community in a nutrient-enriched coastal environment along the southwest coast of India
(Springer, 2017)The relative grazing impact of Noctiluca scintillans (hereafter referred only Noctiluca) and copepods (Acrocalanus gracilis, Paracalanus parvus, Acartia danae and Oithona similis) on the phytoplankton community in an ... -
Role of heavy metals in structuring the microbial community associated with particulate matter in a tropical estuary
(Elsevier, 2017)Particulate matter (PM), which are chemically and biochemically complicated particles, accommodate a plethora of microorganisms. In the present study, we report the influence of heavy metal pollution on the abundance and ... -
Temporal variability in copepod gut pigments over the central western continental shelf of India
(Cambridge University Press, 2018)The Indian Western continental shelf (IWCS) is amongst the most productive regions of the world, being noteworthy for upwelling (south-west monsoon) and downwelling (north-east monsoon) that tunes the water biogeochemistry. ... -
Impact of abrupt weather change on benthic life: a note on sea hare in a tropical coast, Gujarat, India
(Current Science Association, IAS, 2017)An oceanographic survey was undertaken in the low slope intertidal zone of the coast of Okha, Gujarat on 7th and 8th January, 2017. The region is represented by mixture of various small scale habitats. On 7th January, live ... -
Upwelling induced changes in the abundance and community structure of archaea and bacteria in a recurring mud bank along the southwest coast of India
(Elsevier, 2018)The present study reports the influence of upwelling on the abundance and community structure of archaea and bacteria in a mud bank formed along the coastal waters of Alappuzha, the southwest coast of India. The signatures ... -
Effect of UV-B Radiation and Desiccation Stress on Photoprotective Compounds Accumulation in Marine Leptolyngbya sp.
(Springer, 2018)Increased awareness regarding the harmful effects of ultraviolet (UV)-B radiation has led to the search for new sources of natural UV-B protecting compounds. Mycosporine-like amino acids are one of such promising compounds ... -
Methane stimulates massive nitrogen loss from freshwater reservoirs in India
(Nature Publishing Group, 2018)The fate of the enormous amount of reactive nitrogen released to the environment by human activities in India is unknown. Here we show occurrence of seasonal stratification and generally low concentrations of dissolved ... -
Microplastic pollution: A serious threat to the marine ecosystem
(Indian Coast Guard, 2017) -
Tar ball pollution: Research effort and management strategy
(Indian Coast Guard, 2017) -
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 ... -
