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
(Elsevier, 2017)Marine intertidal regions are physically stressful habitats. In such an environment, facilitator species and positive interactions mitigate unfavorable conditions to the benefit of less tolerant organisms. In sponge-brittle ... -
Physiological responses of coastal phytoplankton (Visakhapatnam, SW Bay of Bengal, India) to experimental copper addition
(Elsevier, 2017)Trace amount of copper (Cu) is essential for many physiological processes; however, it can be potentially toxic at elevated levels. The impact of variable Cu concentrations on a coastal phytoplankton community was investigated ... -
Does Glacial-Interglacial Transition Affect Sediment Accumulation in Monsoon-Dominated Regions?
(Wiley, 2017)The spatio?temporal changes in sedimentation rate along the continental margin of the monsoon?dominated eastern Arabian Sea during the last 24 kyr have been estimated from a compilation of 58 radiocarbon dated cores, in ... -
Decolorization of Congo red mediated by marine Alcaligenes species isolated from Indian West coast sediments
(Springer, 2017)Alcaligenes species capable of degrading highly recalcitrant, carcinogenic, water-soluble dye-Congo red-were isolated from Indian West coastal sediments. Individual strains showed decolorization rates ranging from 76.49 ... -
Morphology and chemical composition of ash layer of about 8 Ma old from ODP-758 site, Bay of Bengal
(CSIR, India, 2017)Glass shards from an ash layer of about 8 Ma old extracted from a core drilled at an ODP-758 site in the Bay of Bengal (BOB) were studied for morphology and chemical composition in order to trace their possible source. ... -
Bacillus lacus sp. nov., isolated from a water sample of a salt lake in India
