Change detection studies in coastal zone features of Goa, India by remote sensing
(Indian Academy of Sciences, 2006)Digital remote sensing data of SPOT-1 (Nov. 1990), IRS-1C (Jan. 2001) and IRS-1D (Jan. 2003) have been subject to maximum likelihood classifier (MLC) to carry out change detection studies in the coastal zone of Goa. The ... -
Antiviral property of marine actinomycetes against white spot syndrome virus in penaeid shrimps
(Indian Academy of Sciences, 2006)Aquaculture farms, particularly in Southeast Asia are facing severe crisis due to increasing incidences of White Spot Syndrome Virus (WSSV). Actinomycetes have provided many important bioactive compounds of high prophylactic ... -
Biological indicators in relation to coastal pollution along Karnataka coast, India
(Elsevier, 2006)A comparison has been made of sand, silt, and clay percentage of 118 samples from the Ayeyarwady continental shelf, northern Andaman Sea, measured by the sieve–laser diffraction technique and by classical sieve-pipette ... -
Application of foraminifers in ecotoxicology: Retrospect, perspect and prospect
(Elsevier, 2006)In view of the extensive use of foraminifers for the pollution monitoring especially their unmatched utility in deciphering the temporal variation in the type and concentration of pollutants at a given location, the ... -
Determination of the platinum - group elements (PGE) and gold (Au) in the manganese nodule reference samples by nickel sulfide fire-assay and Te coprecipitation with ICP-MS
(NISCAIR, CSIR, 2006)Platinum group elements (PGE) and Au data in polymetallic oceanic ferromanganese nodule reference samples and crust samples obtained by inductively coupled plasma mass spectrometry (ICP-MS), after separation and pre-concentration ... -
Detection of Trichodesmium bloom patches along the eastern Arabian Sea by IRS-P4/OCM ocean color sensor and by in-situ measurements
(NISCAIR, CSIR, 2005)The detection of blooms of the marine cyanobacterium Trichodesmium from space has been studied using high resolution ocean color imagery in the visible wavebands of the OCM monitor (Ocean Color Monitor) on the IRS-P4 ... -
Utility of natural generalised inverse technique in the interpretation of dyke structures
(NISCAIR, CSIR, 2005)Forward and Inverse methods of magnetic interpretation have been used to estimate the parameters of dyke like intrusion over the eastern continental shelf of India. In the forward problem, the tentative parameters of the ... -
Delta ¹³C depleted oceans before the termination 2: More nutrient-rich deep-water formation or light-carbon transfer?
(NISCAIR, CSIR, 2005)Carbon-isotopes (delta ¹³C) composition of benthic foraminifera has been extensively used to understand the link between deep-water circulation and climate. Equatorial Indian Ocean delta ¹³C records of planktic- and ... -
ENSO signature in the sea level along the coastline of Indian subcontinent
(NISCAIR, CSIR, 2005)Evidence for the signature of El Nino-Southern Oscillation (ENSO) phenomenon in the monthly mean sea level at 8 tide gauge stations on the west coast and 7 stations on the east coast of the Indian subcontinent is presented. ... -

Integrated geophysical studies over the 85°E ridge - Evaluation and interpretation
(AP Akademi of Sciences, India, 2000)Ship-borne magnetic, gravity, bathymetry and multichannel seismic reflection studies made so far on the linear subsurface ridge known as the 85°E Ridge in the northeastern Indian Ocean are reviewed. The extent and boundaries ... -
Continental margin of Andhra Pradesh: Some new problems and perspectives
(AP Akademi of Sciences, India, 1999)The continental margin of Andhra Pradesh from Nellore (14°N) in the south to Baruva (around 19°N) in the north can be classified into two major parts, viz., the non-basinal, Baruva - Visakhapatnam - Kakinada margin and the ... -
Chlorophyll: The wonder pigment
(NISCAIR, CSIR, 2005)Chlorophyll, the green plant pigment, a 'real life force' of living beings, besides synthesizing food, is a great source of vitamins, minerals and other phytochemicals. Adding chlorophyll rich food to our diet fortifies ... -
Tiny, silent killers
(NISCAIR, CSIR, 2005)Inspite of being essential to man's existence in many ways, phytoplankton, a group of microscopic plants, catch our attention only when they create havoc in the seas around us. The 'Red tide', one such bizarre and enigmatic ... -
Waves in the seas
(NISCAIR, CSIR, 1996)Not all sea waves look alike in form. Scientists, in fact, classify all waves into definite groups, which can be simulated on a computer using specific models. Thus there are many types of wave forms on the sea surface ... -
El Nino: The climate changer
(NISCAIR, CSIR, 1986)EL Nino is an abnormal warm situation in the Pacific Ocean which manifests once in a few years due to ocean-atmosphere interaction. It is much talked about inrecent times because it is believed to be'associated with floods, ... -
Addressing environmental issues through foraminifera – Case studies from the Arabian Sea
(The Palaeontological Society of India, 2005)The present global scenario poses multiple environmental problems such as the green house effect, ozone holes, global warming and consequential sea level rise, all being attributed to anthropogenic contributions. Obviously, ... -
Foramgeographical affinities of the west and east coasts of India: An approach through cluster analysis and comparison of taxonomical, environmental and ecological parameters of Recent foraminiferal thanatotopes
