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 70 kyr record of monsoon-induced marine productivity changes, terrigenous flux and weathering variations in the southern Bay of Bengal
(Geological Society of India - GeoScienceWorld, 2024)The southwest (SW) and northeast (NE) monsoon winds significantly affect the oceanographic and climatic changes over the Bay of Bengal (BoB). We present here detailed geochemical and isotopic records from two sediment cores ... -
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 ... -
A brief report on mets system
(National Institute of Oceanography, 2005)Mets system is basically a gas monitoring system, used for the detection of underwater gas. The system consists of a sensor, datalogger and energy module. The sensor works on the diffusion techniques. The system can be ... -
A brief report on the 2nd PAGES Young Scientists Meeting in Goa, India
(PAGES, 2013)The Past Global Changes (PAGES) project, an internationally funded effort that aims to facilitate and encourage climate science across countries and disciplines, experimented with a different type of conference four years ... -
A brief study on the imprints of seismo tectonic activities in the crust of central and southern Bay of Bengal
(Association of Exploration Geophysicists, 2007)Bathymetry, magnetic and shallow seismic data collected north and south off Visakhapatnam revealed the extension of onshore lineaments to offshore. Stability of the area has been studied from the physical properties of ... -
A case for riverine archaeology in India
(Society for Marine Archaeology, Goa, 1991)The main objective is to study the river routes and excavate submerged river ports and preserve them for posterity. The ancient cities situated on the bank of the river Ganga such as Varanasi, Pataliputra and Tamralipti ... -
A case study on the impact of industrial effluent disposal on the fishery of Amba River Estuary, Maharashtra
(Indian Fisheries Association, 1995)The impact of waste discharge on fishery resources is a matter of great concern. The accepted norm in all environmental impact assessment studies is to avoid areas of high fishery potential while locating a marine outfall. ... -
A Cenozoic record of the equatorial Pacific carbonate compensation depth
(Nature Publishing Group, 2012)Atmospheric carbon dioxide concentrations and climate are regulated on geological timescales by the balance between carbon input from volcanic and metamorphic outgassing and its removal by weathering feedbacks; these ... -
A century of climate variability in central Dronning Maud Land, East Antarctica, and its relation to Southern Annular Mode and El Nino-Southern Oscillation
(American Geophysical Union, 2010)Stable isotope records of oxygen and hydrogen were studied from a 65 m long ice core retrieved from central Dronning Maud Land, East Antarctica, in order to reconstruct the coastal Antarctic climate variability during the ... -
