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 ... -
A Printable Device for Measuring Clarity and Colour in Lake and Nearshore Waters
(Multidisciplinary Digital Publishing Institute- MDPI AG, Basel, Switzerland, 2019)Two expanding areas of science and technology are citizen science and three-dimensional (3D) printing. Citizen science has a proven capability to generate reliable data and contribute to unexpected scientific discovery. ... -
In vivo DNA damage in gill, haemolymph and muscle cells of whiteleg shrimp Litopenaeus vannamei on exposure to organophosphorus pesticide
(Inter-Research Science Center, Oldendorf/Luhe, Germany, 2019)In response to growing worldwide market demand, intensive shrimp farming, particularly of whiteleg shrimp Litopenaeus vannamei, has expanded tremendously. The present study investigated induced DNA damage in gill (GL), ... -
Pyrrole-Derived Alkaloids of Marine Sponges and Their Biological Properties
(Elsevier, 2019)Marine sponges remain an unambiguously significant source of secondary metabolites from marine invertebrates. It is estimated that more than 15,000 compounds have been discovered from marine sources, and new compounds are ... -
Evaluation of the reanalysis wind over the Indian Ocean across the seasonal reversing wind pattern
(NISCAIR-CSIR, India, 2019)Present study show the similarity as well as contradictory event among the four different wind data based on monthly, seasonally and annual wind pattern over Indian Ocean. All the four reanalysis wind sources exhibit almost ... -
Significant seasonal contrast in the Arabian Sea during deglaciation: Evidence from oxygen isotopic analyses of individual planktic foraminifera
(Elsevier, 2019)The variation of stable isotopes between individual shells of planktic foraminifera of a given species and size may provide short-term seasonal insight into past sea surface temperature (SST) and salinity (SSS). In this ... -
Impact of the Indian Summer Monsoon variability on the source area weathering in the Indo-Burman ranges during the last 21-kyr - A sediment record from the Andaman Sea
