A deep-sea hydrogen peroxide-stable alkaline serine protease from Aspergillus flavus
(Springer Science and Business Media Deutschland GmbH, 2020)We report here the production of an alkaline serine protease by Aspergillus flavus isolated at 5600-m depth from deep-sea sediments of the Central Indian Basin. When grown on defatted groundnut oil meal at 30��C for 48-72�h, ... -
A description of sediment cores from the Arabian Sea
(1972)This study describes in detail the lithologic character of five sediment cores from the Arabian Sea (shelf, slope, and basins) and summarizes the distribution and occurrence of their characteristic lithofacies and biofacies ... -
A device for biofouling studies in estuaries in relation to the tidal cycle
(Indian Association for Limnology and Oceanography, 1985)A device developed for studying the bio-ecological processes in an estuary in relation to the tidal flow is described. The deployment of this device could provide continuous and reliable data which will, not only minimize ... -
A device for continuous microscopic examination of aquatic microorganisms
(CSIR-NISCAIR, 1987)The device consists of a sealed microscopic mount provided with an inlet for liquid medium and an outlet, permitting continuous flow of the liquid. It permits observation of development of marine microorganisms such as ... -
A device for finer-scale sub-sectioning of aqueous sediments
(Indian Academy of Sciences, 2007)A modified hand-operated mechanical device has been developed to facilitate precise sectioning of the aqueous sediment in a core liner. The device allows the core liner to remain vertical on the disk protecting physical, ... -

A documentation on burrows in hard substrates of ferromanganese crusts and associated soft sediments from the Central Indian Ocean
(Indian Academy of Sciences, 2000)Substrates of ferromanganese encrustations collected from the hummocky topography of the Central Indian Basin (CIB) (lat. 12~'25'-12~'45'S, water depth between 5150 and 5300 m) are largely composed of indurated claystone ... -
A finite element simulation of tidal circulation in the Gulf of Kutch, India
(Elsevier, 2003)A finite element (fe) model using the software package ADCTRC was developed to simulate the tides and currents in the Gulf of Kutch, located on the northwest coast of India. The surface elevations from the model were ... -
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 ... -
A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera
(AGU, 2005)Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last approx. 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record ... -
A first look at the dinoflagellate cysts abundance in the Bay of Bengal: implications on Late Quaternary productivity and climate change
(Current Science Association, 2012)Abundance and composition of dinoflagellate cysts in a sediment core (SK218/1) from the Bay of Bengal were examined for the last 23 kyr. Cyst abundance at this site varied from 20 to 153 cysts/g dry wt, which is far less ... -
A first report on a bloom of the marine prymnesiophycean, Phaeocystis globosa from the Arabian Sea
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2000)A thick bloom of the marine prymnesiophycean, Phaeocystis globosa was observed in the central Arabian Sea during the summer monsoon period (July-August, 1996). The cells were mostly in colonial form, embedded in gelatinous ... -
A foraminiferal testimony for the reduced adverse effects of mining in Zuari Estuary, Goa
(Taylor and Francis, 2005)This paper demonstrates the potentiality of foraminifera in detecting mining pollution. Goa's Mandovi-Zuari estuarine complex is most vulnerable to deterioration caused by the mining industry. The objective of the present ... -
A freak twin trilobite larva of the Indian horseshoe crab Tachypleus gigas (Muller)
(Bombay Natural History Society, 1993)Early embryonic stages of a horseshoe crab Tachypleus gigas were studied using micrographs of live embryo. A freak egg showing two trilobite larvae bridged with each other was noticed on 38th day after fertilization. ... -
A geological and geophysical data collection system
(CUSAT, Kochi, 1992)A geological and geophysical data collection system using a Personal Computer is described below. The system stores data obtained from various survey systems typically installed in a charter vessel and can be used for ... -
A geological data logger
(IEEE Oceanic Engineering Society, 1986)A novel data logger has been designed and tested for logging data from a satellite navigator, magnetometer, and a deep-sea echosounder. The logger exploits the interrupt structure of an in-house 8085 single-board computer ... -
A geophysical survey of the De Gerlache Seamounts: Preliminary results
(Springer, 1998)The De Gerlache Seamounts actually consist of two medium-sized guyots, with summits at depths of 350-600 m. Acoustic profiler data show no significant sediment on these guyots. Alkaline basalts dredged from the summit of ...
