Global Carbon Cycling on a Heterogeneous Seafloor.
(Elsevier, 2018)Diverse biological communities mediate the transformation, transport, and storage of elements fundamental to life on Earth, including carbon, nitrogen, and oxygen. However, global biogeochemical model outcomes can vary by ... -
A review on the distribution of Phylum Phoronida from India with recent observations on Phoronis psammophila
(CSIR, India, 2017)Phoronida is one of the smallest and least familiar phyla. A brief review on the distribution of Phylum Phoronida from India along with current observations on Phoronis psammophila is presented in this article. The aim of ... -
A zona incognita surrounds the secondary nitrite maximum in open-ocean oxygen minimum zones
(Elsevier, 2017)An analytic gap exists between the lower limit of detection of oxygen (O2) by conventional sensors (LOD, ~1 - 3�M O2) and the appearance of NO2- from NO3- reduction (~0.05�M O2), which signifies the secondary nitrite ... -
Seasonal and Interannual Variability in the Barrier Layer of the Bay of Bengal
(Wiley, 2018)An objectively analyzed monthly gridded ocean analysis derived from a combination of satellite and in situ observations is used to describe the seasonal and interannual variability in the barrier layer thickness (BLT) over ... -
Phylogeny and genetic variation within population of Tachypleus gigas (M�ller, 1785)
(Current Science Association, IAS, 2017)Isolated population of Indian horseshoe crabs, Tachy-pleus gigas plays an important role in the ecology of several marine organisms, and is being scrutinized for its abundance and morphology by many researchers. However, ... -
Nature of the Ambient Noise, Site Response, and Orientation of Ocean?Bottom Seismometers (OBSs): Scientific Results of a Passive Seismic Experiment in the Andaman Sea
(Seismological Society of America, 2018)We analyze the nature of the ambient noise and site response for ocean?bottom seismometers (OBSs) deployed in the Andaman region. The probabilistic power spectral densities of the OBSs show that the noise level in the ... -
Iron partitioning during LOHAFEX: Copepod grazing as a major driver for iron recycling in the Southern Ocean
(Elsevier, 2017)The LOHAFEX iron fertilization experiment was conducted for 39days in the closed core of a cyclonic mesoscale eddy located along the Antarctic Polar Front in the Atlantic sector of the Southern Ocean. Mixed layer (ML) ... -
A first look at factors affecting aragonite compensation depth in the eastern Arabian Sea
(Elsevier, 2017)Water column measurements suggest shoaling of aragonite saturation depths (ASD) throughout the world oceans, due to increase in greenhouse gas concentration. Past records of aragonite saturation state under different ... -
Modulation of the Ganges-Brahmaputra River Plume by the Indian Ocean Dipole and Eddies Inferred From Satellite Observations
(Wiley, 2017)The Bay of Bengal receives large amounts of freshwater from the Ganga?Brahmaputra (GB) river during the summer monsoon. The resulting upper?ocean freshening influences seasonal rainfall, cyclones, and biological productivity. ... -
Statistical assessment to magnetic susceptibility and heavy metal data for characterizing the coastal sediment of East coast of Tamilnadu, India
(Pergamon, 2018)A rapid urbanization and industrialization enhances the significant heavy metal pollution in the sediments of coastal area and introduced a serious threat to the human health. In the present study, concentration of heavy ... -
Particulate Organic Carbon Composition in Temperature Fronts of the Northeastern Arabian Sea during Winter
(Wiley, 2018)In order to understand the major sources of particulate organic carbon (POC) in the frontal zones and to examine their variability with space and time, a total of five temperature fronts of different ages was sampled in ... -
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 ... -
