Aspernolides A and B, butenolides from a marine-derived fungus Aspergillus terreus
(Elsevier, 2009)Two aromatic butenolides, aspernolides A and B along with the known metabolites, butyrolactone I, terrein and physcion were isolated from the fermentation broth of a soft coral derived fungus Aspergillus terreus. The ... -
Assemblage of benthic diatoms and culturable heterotrophs in shallow-water hydrothermal vent of the D. Joao de Castro Seamount, Azores in the Atlantic Ocean
(Current Science Association, India, 2008)The shallow-water hydrothermal vent of D. Joao de Castro Seamount in the North Atlantic, between the Azorean islands Sao Miguel and Terceira, is characterized by yellow and white zones which are distinct in physical and ... -
Assessing metal contamination in recent creek sediments using fractionation technique along Mumbai coast, India
(Springer and Business Media, 2017)Three sediment cores from a creek environment in Mumbai, extending from the head to the creek mouth, were studied with respect to elements (Fe, Mn, Cu, Pb, Co, Zn and Cr) along with organic matter (total organic carbon, ... -
Assessing seasonal nitrogen transformations in the Godavari estuary, India
(Elsevier, 2023)Indian estuaries are hypothesized to export a significant amount of nitrogen nutrients to the coastal waters due to the high use of fertilizers. To examine the possible sources of nitrogen nutrients and their modifications ... -
Assessing the changes in protein content during the ensilage of the Indian Mackerel (Rastrelliger kanagurta) by biological method
(Springer, 2024)Fish silage is a liquefied product resulting from tissue hydrolysis and the richness of the silage is characterized by its nutritional profile comprising of proteins, amino acids, and fats. For the production of fish silage ... -
Assessing the distribution and abundance of seabed minerals from seafloor photographic data in the Central Indian Ocean Basin
(Taylor & Francis, 2013)Distribution characteristics of deep-sea mineral resources such as polymetallic nodules and ferromanganese crusts are often influenced by local seafloor features such as the topographic undulations and sediment thickness. ... -
Assessing the ecological preferences of agglutinated benthic foraminiferal morphogroups from the western Bay of Bengal
(2019)Agglutinated benthic foraminiferal morphogroups have often been used as a proxy in paleoecological studies. The response of various agglutinated morphogroups may, however, vary regionally. Here we report the ecological ... -
Assessing the effect of calcein incorporation on physiological processes of benthic foraminifera
(Elsevier, 2015)Rosalina sp. was incubated in seawater spiked with calcein (5 mg/l to 20 mg/l calcein), a dye proposed as efficient marker to tag newly formed calcite, to understand its effect on benthic foraminifera. The experiment was ... -
Assessing the effect of leachate of copper slag from the ISASMELT process on cell growth and proximate components in microalgae, Chlorella vulgaris (Beijerinck)
(Taylor & Francis, 2011)Dumping or disposal of huge quantities of slag (containing significant amounts of heavy metals) generated during matte smelting and refining of copper (Cu) is likely to result in environmental toxicity. Detailed chemical ... -
Assessing the effect of riverine discharge on planktic foraminifera: A case study from the marginal marine regions of the western Bay of Bengal
(Elsevier, 2021)Planktic foraminifera are amongst the most widely used paleoclimatic proxies. The application of foraminifera for paleoclimatic reconstruction requires knowledge of the ecological preference of species. Here, we report the ... -
Assessing the environmental significance of benthic foraminiferal morpho-groups from the northern high latitudinal regions
(Elsevier, 2018)The spatial distribution of benthic foraminiferal morpho-groups has been documented from the Kongsfjorden-Krossfjorden, to assess its environmental significance. Benthic foraminiferal abundance increases from the inner-most ... -
Assessing the geographical distribution of carnivorous and planktivorous fishes in the western Bay of Bengal
(Elsevier, 2023)There is a clear distinction in the feeding habits of fishes between the northeastern and southeastern Arabian Sea (west coast of India) � the north is carnivorous, and the south is planktivorous �, but such a distinction ... -
Assessing the source of oil deposited in the surface sediment of Mormugao Port, Goa - A case study of MV Qing incident
(2019)In June 2016, a cruise vessel was grounded in the Mormugao Port, resulting in unnoticed oil spill. The surface water and sediment samples were collected from the vicinity of the ship, and also an oil sample from the ship ... -
Assessing the suitability of benthic foraminiferal morpho-groups to reconstruct paleomonsoon from Bay of Bengal
(Indian Academy of Sciences, 2016)Temporal changes in benthic foraminiferal morpho-groups were suggested as an effective proxy to reconstruct past monsoon intensity from the Arabian Sea. Here, in order to test the applicability of temporal variation in ... -
Assessment of aeolian dust concentration, elemental composition, and their wet and dry deposition fluxes over the Northeast Arabian Sea
(Taylor & Francis, 2022)Atmospheric aerosol over the Arabian Sea is significantly impacted by the long-range transported mineral dust from the surrounding continents.This transported mineral dust is hypothesized and tested during several studies ... -
Assessment of biological characteristics on coastal environment of Murud (Maharashtra) during the oil spill (17 May 1993)
(NISCAIR, CSIR, 1995)A rupture of a feeder riser pipeline resulted in spillage of crude oil estimated to be 3000-8000 tonnes in Bombay High Region on 17 May 1993. The treated spill broken down into several patches and drifted south and finally ... -
Assessment of coastal wetland resources of central west coast, India, using LANDSAT data
(The Indian Society of Remote Sensing, 2001)The part of central west coast (Maharashtra and Goa) of India has been classified and quantified for coastal wetlands using LANDSAT data of 1985-86. The classification accuracy of the maps and area estimates achieved was ... -
