Immediate response of meio and macrobenthos to disturbance caused by a benthic disturber
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)The probable impact of nodule mining on benthic biota was studied by creating a benthic disturbance. During the predisturbance study in the Central Indian Basin, box core samples were analyzed for the distribution, composition ... -
Immobilisation of manganese, cobalt and nickel by deep-sea-sediment microbial communities
(Taylor & Francis, 2011)Box core samples BC26 and BC36 from geologically different settings were examined to test the hypothesis that autochthonous microbial communities from polymetallic-nodule-rich Central Indian Basin sediments actively ... -
Immobilization of nickel by bacterial isolates from the Indian Ridge system and the chemical nature of the accumulated metal
(Taylor & Francis, 2010)Bacterial isolates from Carlsberg-Ridge waters were tested for their ability to immobilize Ni. For this, test cultures were suspended for 60 d in seawater with and without added Ni at concentrations of 10 to 10,000 mu M. ... -
Immune response of the short neck clam Paphia malabarica to salinity stress using flow cytometry
(Elsevier, 2017)Paphia malabarica is a predominant and commercially important bivalve in India, persistently challenged by wavering salinity in a monsoon-influenced estuary. To examine the organism's immunological response under such a ... -
Immuno-modulation of settlement cues in the barnacle, Amphibalanus amphitrite: significance of circulating haemocytes
(Springer International Publishing, 2019)Gregarious settlement in barnacles has been attributed to chemical cues originating from the associated microorganisms, lectins, and settlement-inducing protein complex from arthropodin, a glycoprotein present in their ... -
Immunochemical Analyses of Soluble Lens Proteins in some Marine Fishes
(CSIR-NISCAIR, 1980)Soluble eye lens proteins of 10 fishes, belonging to the families Clupeidae, Hemirhamphidae, Lactaridae, Scombridae, Stromatidae, Psettodidae, Bothidae and Soleidae were studied by immunoelectrophoresis using the lens ... -
Immunoecology of the short neck clam Paphia malabarica (Chemnitz, 1782) in a tropical monsoon-influenced estuary
(Elsevier, 2019)Understanding the variability in organism's immunological response is crucial for predicting changes at population or community level. The present study investigated the immunoecology of a commercially valuable clam Paphia ... -
Impact investigations of access channel modifications of Cochin harbour, India
(COPEDEC, 1999)Though the modernization projects over the decades for harbour development also brought about several severe environmental modifications in Cochin harbour, along the west coast of India, so far, the physical processes ... -
Impact microcrater morphology on Australian microtektites
(Meteoritical Society, 2003)Scanning electron microscopy of 137 Australian microtekties and fragments from 4 sediments cores in the Central Indian Ocean reveals more than 2000 impact-generated features in the size range of 0.3 to 600 mu m. Three ... -
Impact microcraters on an Australasian microtektite
(Meteoritical Society, Fayetteville, USA, 1996)Microcraters attributable to impact have been discovered on an Australasian microtektite from a core in the Central Indian Basin. The craters resemble lunar microcraters and those generated during impact experiments. The ... -
Impact of 'Chitra' oil spill on tidal pool macrobenthic communities of a tropical rocky shore (Mumbai, India)
(Coastal and Estuarine Research Federation, 2014)A collision between the ships MSC Chitra and MV Khalijia 3 in the mouth region of Mumbai Harbour led to a leakage of around 800 t of fuel oil in August 2010, affecting the rocky intertidal region of Colaba. To evaluate the ... -
Impact of 1990-'95 ENSO/WEPO event on Indian monsoon rainfall
(NISCAIR, CSIR, 1997)The negative phase of the 1990-'95 El Nino-Southern Oscillation (ENSO) and the associated Warming of the Equatorial Pacific Ocean (WEPO) was the longest observed in the 113 years of its recorded history, compared to its ... -
Impact of 2004 co-seismic coastal uplift on the mangrove cover along the North Andaman Islands
(Springer, 2020)The December 2004 earthquake and the subsequent tsunami have incurred devastating impacts on vital habitats along the Indian coastal region, where few of them are irreversible. The earthquake has uplifted the northern ... -
Impact of 2015-2016 ENSO on the winter bloom and associated phytoplankton community shift in the northeastern Arabian Sea
(Elsevier, 2018)The present study explores the impact of 2015-16 El-Niño Southern Oscillation (ENSO) on the winter phytoplankton bloom in the northeastern Arabian Sea (NEAS). In situ Chlorophyll a (Chla) from the bio-Argo float (2013-2016) ... -
Impact of a large hydraulic barrage on the trace metals concentration in mesozooplankton in the Kochi backwaters, along the Southwest coast of India
(Elsevier Ltd, 2020)This study delineates the impact of a man-made hydrological barrage [Thannermukkom barrage (TB)] on the concentration of selected trace metals (Fe, Zn, Cu, Co, Cr, Mn, Ni, Pb) in mesozooplankton from the Kochi backwaters ... -
Impact of abrupt weather change on benthic life: a note on sea hare in a tropical coast, Gujarat, India
(Current Science Association, IAS, 2017)An oceanographic survey was undertaken in the low slope intertidal zone of the coast of Okha, Gujarat on 7th and 8th January, 2017. The region is represented by mixture of various small scale habitats. On 7th January, live ... -
Impact of accidental leakage of furnace oil on Mahul creek mangrove vegetation
