Organically Associated Copper in Mandovi and Zuari Estuaries
(Indian Association for Limnology and Oceanography, 1981)Studies were conducted to determine the extent to which copper is associated with organic matter in the estuarine and riverine waters of Mandovi and Zuari. It was observed that in the Mandovi the organically associated ... -
Organochlorine pesticide compounds in organisms from the Bay of Bengal
(Elsevier, 1994)Zooplankton and bottom-feeding fish (four species) from the coastal Bay of Bengal were analysed for residues of DDT, DDD, DDE and aldrin, Concentrations of t-DDT (DDT+DDD+DDE) ranging from 1.31 to 115.90 ngg @u-1@@ wet ... -
Organochlorine pesticide residues in the northern Indian Ocean
(Oxford and IBH, New Delhi, 1992)The coastal waters of India receive about 4.4Km sup(3) of domestic sewage and 0.44 Km sup(3) of industrial wastes, annually. A concerted effort is being made for about a decade now to assess the state of the Indian marine ... -
Organochlorine residues in zooplankton off the Saurashtra coast, India
(Elsevier, 1987)Zooplankton samples were collected by neuston net (250 mu m) at the sea surface for about 40 min -
Organotins in the sediments of the Zuari estuary, west coast of India
(Elsevier, 2009)Industrial use of organotins such as butyltins and phenyltins has increased several folds during the last two decades. Butyltins and phenyltins are synthetic, multipurpose chemicals, which have been extensively used in ... -
Origin and biochemical cycling of particulate nitrogen in the Mandovi estuary
(Elsevier, 2011)Mandovi estuary is a tropical estuary strongly influenced by the southwest monsoon. In order to understand, sources and fate of particulate organic nitrogen, suspended particulate matter (SPM) collected from various ... -
Origin and distribution of shallow gas-charged sediment on the inner continental shelf of central west coast of India
(2019)High-resolution shallow seismic investigations on inner continental shelf of Goa have been carried out to map gas-charged sediment zones and investigate origin of trapped gas. Analyses of data reveal that the gas is trapped ... -
Origin and significance of high-grade phosphorite in a sediment core from the continental slope off Goa, India
(Current Science Association, Bangalore, India, 1995)A phosphorite crust was found at 380-390 cm depth interval of a sediment core collected from the topographic high occurring on the continental slope off Goa. This crust is fragile and grey to light brown in colour. Carbonate ... -
Origin of amphibole-rich beach sands from Tila-Mati, Karwar, central-west coast of India
(Geological Society of India, 1996)The pocket beach at Tila-Mati, Karwar, central west coast of India, is characterised by the occurrence of amphibole-rich (chiefly tremolite-actinolite) coarse sand in the zone of minimal impact of waves and currents. In ... -
Origin of ash in the Central Indian Ocean Basin and its implication for the volume estimate of the 74,000 year BP Youngest Toba eruption
(Indian Academy of Sciences, 2002)A controversy exists about the origin of ash in the Central Indian Ocean Basin (CIOB). In situ silicic volcanism and Indonesian arc volcanism have been proposed as sources of ash in the basin. We present here the detailed ... -
Origin of cretaceous phosphorites from the onshore of Tamil Nadu, India
(Indian Academy of Science, 2007)Cretaceous phosphorites from the onshore of Tamil Nadu have been investigated for their origin and compared with those in the offshore. Cretaceous phosphorites occur as light brown to yellowish brown or white nodules in ... -
Origins of wind-driven intraseasonal sea level variations in the North Indian Ocean coastal waveguide
(American Geophysical Union, 2013)In this paper, it is shown that a linear, continuously stratified ocean model reproduces observed wind-driven intraseasonal sea level variability in the coastal waveguide of the Northern Indian Ocean (NIO). Sensitivity ... -
Oscillating environmental responses of the eastern Arabian Sea
(CSIR-NISCAIR, 2014)Characteristics of two distinct physical processes, the coastal upwelling and convective overturning, which enhance phytoplankton productivity in the west coast of India, are discussed in this study. Systematic in-situ ... -
Ostracod biodiversity from shelf to slope oceanic conditions, off central Bay of Bengal, India
(Elsevier, 2017)Thirty seven surface sediment samples collected through a multi-corer in seven transects of ORV Sagar Kanya, SK 308 Leg-1 from off central Bay of Bengal (shelf to slope environment) were analysed for living and dead ... -
Ostracoda from Vestfold Hill lake terraces, Antarctica
(Geological Society of India, 1984)Six species of ostracodes are recorded from two transects of terraces of Deep Lake, Vestfold Hills, Antarctica. Two species (@iXesteleberis@@ sp. and @iBradleya dictyon@@) range from Cretaceous to Recent, @iPoseidonamicus ... -
Ostracods of Andaman Sea
(Department of Ocean Development, New Delhi (India), 1996)Distribution of 12 species of ostracods was studied from the waters around Andaman-Nicobar area. Euconchoecia aculeata was the most abundant species occurring mostly as swarms with a maximum density of 9732 specimens/1000 ... -
Otoliths in continental shelf and slope surficial sediments off Saurashtra, Arabian Sea, India and their significance
(New Academic Publishers, Delhi, 2001)Otoliths are a viable and underutlized paleoceanographic tool. In India a considerable amount of work has been done on otoliths of the fresh water fishes, however no significant report is available for marine otoliths. In ... -
Our changing coastlines
(CSIR-NISCAIR, 1989)Our coastlines keep alive the sense of continuing creation and of the relentless drive of life In recent years, much has been done both to understand the processes that underlie their creation and to exploit their environment ... -
Our threatened archaeological heritage: A case study from the Tamil Nadu Coast
(Current Science Association, Bangalore, 1997)From the beginning of the Christian era, a number of sites having contact with the Roman world were in existence on the coastal belt of India. There are several indirect references in the literature which suggest that the ... -
