5 alpha - cholestane -3,6-dione from the red alga Acantophora spicifera
(Elsevier, 1987) -
5(R)-Acetoxyspata-13,17-diene, a novel diterpenoid from the brown alga Stoechospermum marginatum
(Thieme Medical Publishers, 1988) -
(-)-6 alpha hydroxy polyanthellian A - A novel antifouling diterpenoid from the Indian soft coral Cladiella krempfi (Hickson)
(NRC Research Press, 2011)Bioassay-guided purification of methanol extract of the soft coral Cladiella krempfi (Octocorallia: Alcynocea) yielded a novel eunicellin-type diterpenoid, (-)-6 alpha-hydroxy polyanthellin A (1), active against the cyprids ... -
60 Myr records of major elements and Pb-Nd isotopes from hydrogenous ferromanganese crusts: Reconstruction of seawater paleochemistry
(Pergamon, 1999)The time series of major element geochemical and Pb- and Ni-isotopic composition obtained for seven hydrogenous ferromanganese crusts from the Atlantic, Indian, and Pacific Oceans which cover the last 60 Myr are compared. ... -
70 kD stress protein (Hsp70) analysis in living shallow-water benthic foraminifera
(Taylor & Francis, 2012)Hsp70 is a phylogenetically highly conserved protein family present in all eukaryotic organisms tested so far. Its synthesis is induced by proteotoxic stress. The detection of Hsp70 in foraminifera is presented here. We ... -
70 kyr record of denitrification and oxygenation changes in the eastern Arabian Sea
(Geochemical Society of Japan, 2017)A 70 kyr record of ?15N from the eastern Arabian Sea, Core AAS9/21 was investigated. High ?15N values during interglacials and low ?15N values during glacials are documented, which mimics the global ?15N records in the ... -
A 16-kyr Record of Ocean Circulation and Monsoon Intensification From the Central Bay of Bengal
(John Wiley & Sons, 2019)The monsoonal signal dominates most climate records from the Indian Ocean. As a consequence, conventional stable isotope tracers have not been effective at tracking ocean circulation in the Indian Ocean and distinguishing ... -
A 25 ky BP record of Himalayan aridity using muscovite and clays as proxy climate indicators
(Museo Geologico di Bologna, 1999)Based upon the temporal variations in the grain size parameters, characteristic clay minerals, their ratios and detrital muscovite content in a isotopically dated turbidity free core from hemipelagic environment. (2713 m ... -
A 27,000 year record of Red Sea outflow: Implication for timing of post-glacial monsoon intensification
(American Geophysical Union, 1996)The history of the Red Sea Outflow (RSO) over the past 27,000 years from an AMS sup(14) C-dated high-resolution Delta sup(13) C record of benthic foraminifera from the inner Gulf of Aden assuming the dominance of circulation ... -
A 50 kyr record of eolian sedimentation in the Eastern Arabian Sea - Dust deposition changes synchronous with the Northern Hemisphere Climatic Oscillations
(Elsevier, 2023)The Late Pleistocene Northern Hemisphere (NH) climate was extremely variable, owing to the abrupt warm Dansgaard-Oeschger (D/O) events and cold Heinrich events in the Greenland and North Atlantic. Although the close coupling ... -
A assessment of the fishery resources for non-penaeid prawns in India
(Cochin: CMFRI, 1968)Prawns other than penaeids account for an average annual production of nearly 34 thousand tonnes, not including the production figures of brackish water palaemonid prawns from the various lakes and backwaters along the ... -
A baseline study of trace metals in a coral reef sedimentary environment, Lakshadweep Archipelago
(Springer, 2010)Surficial and core samples collected from the sedimentary microenvironments of Lakshadweep Archipelago were analysed for their trace metal contents. The synoptical relations in spatial distributions with respect to ... -
A biweekly mode in the equatorial Indian Ocean
(American Geophysical Union, 2004)The National Institute of Oceanography, Goa, India, deployed moorings with several subsurface current meters at 0 degrees, 93 degrees E (in February 2000) and 0 degrees, 83 degrees E (in December 2000) in the eastern Indian ... -
A brief account of the commensals, associates and predators of the marine wood boring animals
(Indian Association for Limnology and Oceanography, 1973) -
A brief description on spatial variability in nutrient-phytoplankton relationship in a shallow tidal creek-Thane Creek, India
(Elsevier, 2022)Anthropogenic influence on nutrient-phytoplanktonrelationship was studied in Thane Creek. The upper creek was highly loaded with N-forms through anthropogenic inputs. The elevated level of nutrients enhanced the chlorophyll ... -
A brief overview of state-of-the-art electronics in physical oceanographic instrumentation
(Goa College of Engineering, 2010)A brief overview of the recent trends in physical oceanographic instrumentation in which recent developments in electronics technology play a crucial role has been given. The electronic instruments mainly utilized in the ... -
