Influence of elevated temperature, pCO2, and nutrients on larva-biofilm interaction: Elucidation with acorn barnacle, Balanus�amphitrite Darwin (Cirripedia: Thoracica)
(Elsevier, 2017)Selection of optimal habitat by larvae of sessile organism is influenced by cues offered by the biofilm. Ocean warming and acidification are likely to enforce changes in the biofilm community and inturn influence the ... -
Physical control of interannual variations of the winter chlorophyll bloom in the northern Arabian Sea
(Copernicus Publications for EGU, 2017)The northern Arabian Sea hosts a winter chlorophyll bloom, triggered by convective overturning in response to cold and dry northeasterly monsoon winds. Previous studies of interannual variations of this bloom only relied ... -
Variability of the Somali Current and eddies during the southwest monsoon regimes
(Elsevier, 2017)The meso-scale eddies and currents in the Arabian Sea are analyzed using different satellite observations, Simple Oceanic Data Assimilation (SODA) reanalysis, and Ocean Reanalysis System 4 (ORAS4) from 1993 to 2016 to ... -
First quantitative exploration of benthic megafaunal assemblages on the mid-oceanic ridge system of the Carlsberg Ridge, Indian Ocean
(Cambridge University Press, 2017)There are few quantitative studies on deep-sea biodiversity from the Indian Ocean, particularly on the mid-ocean ridges (MOR). We investigated the benthic megafaunal community structure of the Indian Ocean MOR at the ... -
Benthic cycling of phosphorus in the Eastern Arabian Sea: Evidence of present day phosphogenesis
(Elsevier, 2018)Results of a study on phosphorus (P) cycling in the Eastern Arabian Sea provides convincing evidence of present-day phosphogenesis in the study area. This finding contrasts with previous reports of the occurrence of only ... -
Kinetic and equilibrium based fractionation study of Pb in continental shelf sediment of India
(Elsevier, 2017)Two independent analytical methods (kinetic and sequential extraction protocols) were used to understand the distribution, stability, and lability of Pb-sediment complexes in Indian continental shelf. The concentrations ... -
Efficient bioremediation of tannery wastewater by monostrains and consortium of marine Chlorella sp. and Phormidium sp.
(Taylor & Francis, 2018)This study evaluated the bioremediation potential of two marine microalgae Chlorella sp. and Phormidium sp., both individually and in consortium, to reduce various pollutants in tannery wastewater (TW). The microalgae were ... -
Picophytoplankton variability: Influence of winter convective mixing and advection in the northeastern Arabian Sea
(Elsevier, 2018)The deepening of mixed layer and ensuing changes in optical and physicochemical properties of euphotic zone can influence phytoplankton community dynamics in the northeastern Arabian Sea during winter monsoon. The response ... -
Contrasting characteristics of colored dissolved organic matter of the coastal and estuarine waters of Goa during summer
(CSIR, India, 2017)The colored dissolved organic matter (CDOM) was investigated during the summer for the coastal and estuarine waters of Goa using the spectral absorption characteristics of CDOM. Accessions of CDOM were seen all along the ... -
Nutrient stoichiometry and freshwater flow in shaping of phytoplankton population in a tropical monsoonal estuary (Kundalika Estuary)
(Elsevier, 2017)The present study aimed to understand the role of freshwater flow and physico-chemical parameters in influencing the phytoplankton community shift and thereby helping in balancing the ecosystem. The Kundalika estuary (KE) ... -
New records of marine fishes from the coral reefs and deep waters of Gulf of Mannar, India
(Scientific Society of Szczecin, 2017)The coral reefs and deep water ecosystems of Gulf of Mannar support diverse assemblages of marine fishes vulnerable to indiscriminate mechanized fishing. However, lack of comprehensive information on the fish diversity of ... -
Influence of ENSO on the Pacific decadal oscillation in CMIP models
(Springer, 2017)Emerging decadal climate predictions call for an assessment of decadal climate variability in the Coupled Model Intercomparison Project (CMIP) database. In this paper, we evaluate the influence of El Ni�o Southern Oscillation ... -
Relict ooids off northwestern India: Inferences on their genesis and late Quaternary sea level
(Elsevier, 2017)Relict carbonate sands dominated by ooids and faecal pellets are common on the continental shelf, between 60 and 110m, off northwestern India. The shiny tan/white aragonitic ooids closely resemble modern Bahamian ooids, ... -
CO2 induced growth response in a diatom dominated phytoplankton community from SW Bay of Bengal coastal water
(Elsevier, 2017)The ongoing increase in surface seawater CO2 level could potentially impact phytoplankton primary production in coastal waters; however, CO2 sensitivity studies on tropical coastal phytoplankton assemblages are rare. The ... -
Satellite and In Situ Observations of a Phytoplankton Bloom from Coastal Bay of Bengal: Role in pCO2 Modulation
(Springer, 2017)A phytoplankton bloom was monitored in coastal waters of Bay of Bengal and its influence in water column properties was investigated. Significant draw down of CO2 was noted within the vicinity of the bloom associated with ... -
Petrogenetic evolution of Cretaceous Samchampi-Samteran Alkaline Complex, Mikir Hills, Northeastern India: Implications on multiple melting events of heterogeneous plume and metasomatized sub-continental lithospheric mantle
(Elsevier, 2017)The Samchampi (26° 13' N: 93° 18' E)-Samteran (26° 11' N: 93° 25' E) alkaline complex (SSAC) occurs as an intrusion within Precambrian basement gneisses in the Karbi-Anglong district of Assam, Northeastern India. This ... -
Nitric oxide-Serotonin interplay in the cyprid metamorphosis of Balanus amphitrite (Cirripedia, Thoracica)
(Elsevier, 2018)Nitric Oxide (NO) signaling is known to govern the cyprid metamorphosis of barnacle Balanus amphitrite, a potential biofouling organism. This signaling cascade is mainly driven by two important enzymes, Nitric Oxide Synthase ... -
Silicon cycle in Indian estuaries and its control by biogeochemical and anthropogenic processes
(Elsevier, 2017)We study the silicon biogeochemical cycle and its associated parameters in 24 and 18 Indian estuaries during dry and wet periods respectively. We focus more specifically on dissolved Si (DSi), amorphous Si (ASi,) lithogenic ... -
Headwaters to oceans: Ecological and biogeochemical contrasts across the aquatic continuum
(Wiley, 2017)While the disciplines of oceanography and limnology often operate in isolate, freshwater, estuarine, and marine ecosystems are intricately linked. The emphasis of this special issue for Limnology and Oceanography is on the ... -
Differential growth forms of the sponge Biemna fortis govern the abundance of its associated brittle star Ophiactis modesta
