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 ... -
Abundance of sewage-pollution indicator and human pathogenic bacteria in a tropical estuarine complex
(Springer, 2009)Studies on abundance and types of various pollution indicator bacterial populations from tropical estuaries are rare. This study was aimed to estimate current levels of pollution indicator as well as many groups of human ... -
Bacterial standing stock, meiofauna and sediment-nutrient characteristics: Indicators of benthic disturbance in the Central Indian Basin
(Pergamon, 2001)As a part of the environmental impact assessment studies for polymetallic nodule mining, the effect of simulated "benthic disturbance" caused by a benthic hydraulic disturber was studied in the Central Indian Basin (CIB). ... -
Benthic foraminifera as pollution indices in the marine environment of west coast of India
(Universita' degli Studi di Milano, 1984)Two ecosystems affected by acidic pollutants (Thana Creek, Bombay and inshore area of Trivandrum, Kerala) and two other ecosystems affected by alkaline pollutants (Cola Bay, Goa and inshore area of Karwar, Karnataka) were ... -
Benthos of Cochin backwaters receiving industrial effluents
(CSIR-NISCAIR, 1989)Faunal composition of benthos and its spatial and temporal distribution at 9 stations in the northern limb of the Cochin backwaters are studied. An industrial belt is located about 18 km upstream of barmouth, and the ... -
Biodiversity of benthic polychaetes from the coastal waters of Paradip, Bay of Bengal
(Annon., 2007)Polychaete communities of the subtidal waters off Paradip, Orissa, India (Lat, 20 degrees 05 minutes - 20 degrees 20 minutes N and Long. 86 degrees 35 minutes - 86 degrees 60 minutes E) in the Bay of Bengal were studied ... -
Biomarkers of petroleum contamination in the digestive gland of Perna viridis (L.)
(The Scientific and Technological Research Council of Turkey, 2012)Oxidative stress responses were evaluated in the digestive gland tissue of Perna viridis exposed to water accommodated fractions (WAFs) of petrol and diesel at 0.5 percent and 5 percent concentrations over 5-, 10-, and ... -
Deterioration of Early Holocene coral reef due to sea level rise along west coast of India: Benthic foraminiferal testimony
(China University of Geosciences (Beijing), 2012)A total of 103 surface sediment samples collected from the water depth range of 15-3300 m along Vijaydurg-Karwar stretch of central west coast of India were analyzed for foraminiferal content. Relict benthic foraminiferal ... -
Foraminifera as climatic indicators in the sediments of Western Indian continental shelf
(Indian Association for Limnology and Oceanography, 1973)Foraminifera are the single celled microscopic organisms found abundantly in the seas and oceans. The tests of these organisms are preserved in the present sediments of the ocean as in the past, sometimes constituting ... -
Foraminiferal fauna from the Cochin backwaters: Biological indicators of man-made changes in the environment
(K.R. Publishers, Udaipur, 1996)Sixty foraminiferal species belonging to 38 genera and 23 families have been recorded from grab sediments of the Cochin backwaters. Of all the species Ammonia baccarii is the most dominant and successful form in the throes ... -
Gyrineum natator: A potential indicator of imposex along the Indian coast
(Elsevier, 2006)Imposex related studies have used neogastropods as sentinel organism. In this effort, we elucidate the potential of a mesogastropod, Gyrineum natator, for imposex monitoring on the central west coast of India. Observations ... -
Indicator organisms of pollution in Cochin backwaters
(Indian Association for Limnology and Oceanography, 1983)Indicator organisms of organic pollution in two localities in the Cochin backwaters are identified The two sites have different sources of pollution, one from retting of coconut husk and the other from discharge of municipal ... -
Influence of upwelling on distribution of chaetognath (zooplankton) in the oxygen deficient zone of the eastern Arabian Sea.
(Elsevier, 2014)he study addresses the coupled spatial scales in the physico-chemical variables and chaetognaths in the upwelling system of the eastern Arabian Sea during the 2005 summer monsoon. We studied the taxon between 0 and 1000 m ... -
Living coccolithophores during the northeast monsoon from the Equatorial Indian Ocean: Implications on hydrography
(Elsevier, 2005)Water samples collected at five stations along 931E section (1 degrees N-4 degrees S) during the northeast monsoon (12-15 February 2000) at five depths (surface, 50, 100, 150 and 200 m) in the eastern equatorial Indian ... -
Long-term variations in abundance and distribution of sewage pollution indicator and human pathogenic bacteria along the central west coast of India
(Elsevier, 2011)Safe water quality criteria on the load and types of microbial populations are important for human use from fishery, tourism and navigational viewpoints. To understand the variations in sewage pollution indicator and certain ... -
Numerical analyses of soft bottom macroinvertebrates to diagnose the pollution in tropical coastal waters
(Springer, 2003)Soft bottom benthic organisms especially polychaetes are known to adapt as r or k selected strategies to different gradients of pollution. This will result in changes of benthic community structure from that of normal ... -
Occurrence and seasonal variation in distribution of fecal indicator bacteria in Tapi estuary along the West coast of India.
(NISCAIR, 2014)Distribution and occurrence of fecal indicator bacterial in nine different locations along the inner to coastal areas of Tapi estuary during three different seasons like, post-monsoon, pre-monsoon and monsoon were analyzed ... -
Occurrence of Neogloboquadrina pachyderma new subspecies in the shelf-slope sediments of northern Indian Ocean
