Fucoxanthin and pheophytin-a from the marine algae Sargassum cinereum: Isolation, characterization and their feeding deterrent activity on Shrimps
(Indian Chemical Society, 2019)Chemical investigation of the brown alga Sargassum cinereum collected from Goa coast, India led to the isolation of two bioactive pigments viz. pheophytin-a and fucoxanthin in a relatively good concentration. These pigments ... -
Mechanisms of barrier layer formation and erosion from in situ observations in the Bay of Bengal
(2019)During the Bay of Bengal (BoB) Boundary Layer Experiment (BoBBLE) in the southern BoB, time series of microstructure measurements were obtained at 88N, 898E from 4 to 14 July 2016. These observations captured events of ... -
An integrated geophysical study east of the southern Chagos Laccadive Ridge Complex, Central Indian Ocean Basin: Implications for the Rodriguez Triple Junction dynamics in the Late Cretaceous
(2019)The Central Indian Ocean Basin, east of the southern Chagos Laccadive Ridge complex has evolved due to seafloor spreading in the N-S direction since the Late Cretaceous. The trace of the Rodriguez Triple Junction (RTJ)has ... -
On the physical interpretation of the lead relation between Warm Water Volume and the El Ni�o Southern Oscillation
(Springer Berlin Heidelberg, 2019)The Warm Water Volume (WWV), a proxy for the equatorial Pacific heat content, is the most widely used oceanic precursor of the El Ni�o Southern Oscillation (ENSO). The standard interpretation of this lead relation in the ... -
Improvement in biomass, lipid production and biodiesel properties of a euryhaline Chlorella vulgaris NIOCCV on mixotrophic cultivation in wastewater from a fish processing plant
(Elsevier, 2019)In this study, the changes in biomass productivity, wastewater treatment, lipid production and biodiesel properties from mixotrophic cultivation of Chlorella vulgaris NIOCCV in untreated wastewater from a fish processing ... -
Geometry of the Subducting Indian Plate and Local Seismicity in the Andaman Region from the Passive OBS Experiment
(Seismological Society of America, California, USA, 2019)We deployed a temporary passive ocean-bottom seismometer (OBS) network from 25 December 2013 to 15 May 2014 to understand the local seismicity pattern in the Andaman region. A total of 559 local earthquakes are identified ... -
Nitrate Reductase Gene Expression in Idiomarina Strain cos21 Obtained from Oxygen Minimum Zone of Arabian Sea
(Springer US, 2019)This study analyses the induction and repression of nitrate reduction activity in a batch culture of Idiomarina strain cos21. On a change from aerobic to anaerobic respiration, the culture entered a stationary phase. The ... -
Inter-annual variations in the hydrochemistry of Alappuzha mud banks, southwest coast of India
(Elsevier, 2019)The changes in the hydro-chemical properties of a near shore waters of Alappuzha, southwest coast of India, where the mud banks and coastal upwelling are co-existent, are presented based on two time-series measurements ... -
A review on SIFT and SURF for underwater image feature detection and matching
(Institute of Electrical and Electronic Engineers, Inc. USA, 2019)Fast and robust image recognition and matching is an important task in the underwater domain. Autonomous Underwater Vehicles (AUV) use images for detecting and recognising object or scene of interest. Interest points are ... -
Involvement of inducible nitric oxide synthase (iNOS) in immune-functioning of Paphia malabarica (Chemnitz, 1782)
(Elsevier, 2019)In recent years, the role of inducible nitric oxide synthase (iNOS) isoform has been widely studied because of its immunological relevance in higher organisms as well as invertebrates including bivalves. However, little ... -
Community structure of benthic amphipods in four estuaries of northwest India
(Elsevier, 2019)This is the first comprehensive study of the community structure and spatial-temporal distribution of amphipods in estuarine sediments of northwest India. Specifically, amphipods from Ulhas, Amba, Kundalika and Savitri ... -
Variability of organic nitrogen and its role in regulating phytoplankton in the eastern Arabian Sea
(Elsevier, 2019)The relative importance of organic nitrogen (ON) and inorganic nitrogen (IN) as nitrogen sources for the phytoplankton communities were studied through a seasonal time series of nitrogen species in the eastern Arabian Sea. ... -
The ballast effect of lithogenic matter and its influences on the carbon fluxes in the Indian Ocean
(European Geosciences Union, 2019)Data obtained from long-term sediment trap experiments in the Indian Ocean in conjunction with satellite observations illustrate the influence of primary production and the ballast effect on organic carbon flux into the ... -
The first record of active methane (cold) seep ecosystem associated with shallow methane hydrate from the Indian EEZ
(Springer India, 2019)Here we report the discovery of cold-seep ecosystem and shallow methane hydrates (2-3 mbsf) associated with methane gas flares in the water column from the Indian EEZ for the first time. The seep-sites are located in the ... -
Sea level-controlled sediment transport to the eastern Arabian Sea over the past 600 kyr: Clay minerals and SrNd isotopic evidence from IODP site U1457
(Elsevier, 2019)Long marine sequences deposited in the Arabian Sea are suitable to study the orbital sensitivity of sediment dynamics from a source-to-sink perspective. The clay mineralogy and SrNd isotopic compositions have been analyzed ... -
