Software interface system for Geophysical Data Access and Management System (GPDAMS-CD)
(National Institute of Oceanography, India, 2004)This report examines the principles underlying GPDAMS, philosophy behind data management, and describes functionalities, limitations and usage of GPDAMS. GPDAMS is a complete marine geophysical data management system that ... -
Artificial neural networks and its application in coastal urban development
(National Institute of Technology, Surathkal, 2004)This paper briefly highlight the basics of the artificial nueral network so that it will be easy to understand its applicability and also highlight some applications related to urban development -
Natural isotopic composition of nitrogen in suspended particulate matter in the Bay of Bengal
(The European Geosciences Union, 2004)The first measurements of nitrogen isotopic composition (delta sup(15) N) in suspended particulate matter (SPM) of the surface Bay of Bengal (BOB) at 24 different locations during pre- (April-May 2003) and post- ... -
Petroleum hydrocarbon residues in the marine environment of Bassein-Mumbai
(Elsevier, 2004)The paper reports PHc contamination in water, sediment and biota of the coastal area of Bassein-Mumbai in relation to relatively less polluted sites (Dabhol and Ratnagiri, Maharashtra) off the west coast of India. To ... -
New C sub(21) Delta sup(20) pregnanes, inhibitors of mitochondrial respiratory chain,from Indopacific octocoral Carijoa sp.
(Elsevier, 2004)Two new compounds, pregnanes 1 and 2, the known pregnane 3 and a series of known chlorinated prostanoids (4-9) have been isolated from the Indian octocoral Carijoa sp. Their structures have been elucidated by spectroscopic ... -
New bromotyrosine alkaloids from the marine sponge Psammaplysilla purpurea
(Elsevier, 2004)Seven new bromotyrosine alkaloids Purpurealidin A, B, C, D, F, G, H and the known compounds Purealidin Q, Purpurealidin E, 16-Debromoaplysamine-4 and Purpuramine I have been isolated from the marine sponge Psammaplysilla ... -
Butyltins in water, biofilm, animals and sediments of the west coast of India
(Elsevier, 2004)Biofilm, fish, oyster, mussel, clam, surface seawater, suspended particulate matter (SPM), and sediment samples were collected from marine and/or estuarine waters of the west coast of India. These samples were analysed for ... -
Arabian Sea oceanography and fisheries
(Fishery Survey of India, 2004)The physical and chemical forcing which drive the Arabian production is now fairly well understood. The main attributes, which contribute to the productivity are (1) the boundary processes which manifest as upwelling during ... -
Subtidal micro and meiobenthic community structure in the Gulf of Kachchh
(National Institute of Ocean Technology, 2004)Community structure of the micro- and meiobenthos of subtidal sediment from the Gulf of Kachchh were investigated during April 2002 (premonsoon season). Sediment samples were collected from 23 stations representing the ... -
Seaweed: A valuable marine plant source
(WWF for Nature-India, 2004)Seaweed, one of the components of seashore, is the most unique and important marine living resource. Its multi-ranged applications are of economic as well as ecological importance. These plants have been a source of food, ... -
The larvae of decapods and fishes of Amba estuary, Maharashtra
(Fishery Survey of India, 2004)Larvae of fishes and decapods found in zooplankton collections from two stations (Mankule and Patalganga) in Amba estuary adjoining Mumbai harbour were studied during 1989-90 covering three seasons. The percentage contributions ... -
Nitrogen uptake by size-fractionated plankton in permanently well-mixed temperate coastal waters
(Oxford University Press, 2004)Nitrogen uptake by net- (15-200 mu m), nano- (1-15 mu m) and picoplankton (less than 1 mu m) was measured over seasonal cycles at two stations with different patterns of biological and chemical cycles in the Morlaix Bay ... -
Nitrogen and phosphorus requirements of an Alexandrium minutum bloom in the Penze' Estuary, France
(American Society of Limnology and Oceanography, 2004)During an intense (up to 33 x 10 sup(6) cells L sup(-1)) Alexandrium minutum bloom in the Penze estuary (France), total NO sub(3), NH sub(4), and PO sub(4) requirements of the bloom were, respectively, 184, 25, and 20 mu ... -
Unseen and unsung heroes: The microbes
(WWF for Nature-India, 2004)Fungi are larger microorganisms and their bodies are mostly filamentous, the filaments being called hyphae. It is now believed that fungi evolved from an ancestor that was also common to animals. The width of the fungal ... -
Environmental impact assessment - A management tool for conservation of large marine ecosystems
(Fishery Survey of India, 2004)Coastal development includes a variety of activities which will have significant impact on marine ecosystem especially in the shallow nearshore areas. The stress relevant to coastal zone emerge from hinterland activities, ... -
Vertical migratory rhythms of benthic diatoms in a tropical intertidal sand flat: Influence of irradiance and tides
(Springer, 2004)Vertical migratory behavior of benthic diatoms is one of the adaptive strategies employed for a life in intertidal habitats. Irradiance and tides are considered to be the key factors governing vertical migration. Experiments ... -
