Hydrography of the northern Bay of Bengal during southwest monsoon
(National Institute of Oceanography, Goa, 1989)Hydrography of the Bay of Bengal to the north of 19°N during southwest monsoon is discussed on the basis of temperature, salinity, oxygen and density distribution. The thermohaline features are analysed to understand the ... -
Hydrography of the Wadge bank - premonsoon and monsoon seasons
(Indian Association for Limnology and Oceanography, 1989)The hydrography of the Wadge Bank during premonsoon and monsoon seasons is presented. The thermocline slopes downward towards the central region. Upwelling is prominent in the entire region during monsoon and is observed ... -
Hydrological characteristics and transequatorial transport in the west Indian Ocean
(CSIR-NISCAIR, 1976) -
Hydrological modelling of the west coast of India
(Goa University, 2010)A hydrological modelling framework was assembled for simulating discharges of the west-coast rivers of India. The framework is applied to the Mandovi river, Goa, a typical west-coast river. The modelling framework consisted ... -
Hydrological regulation of Vibrio dynamics in a tropical monsoonal estuary: a classification and regression tree approach
(Springer Science and Business Media Deutschland GmbH, 2021)Dynamics of Vibrio populations in aquatic environments are of concern, as they encompass members pathogenic to humans as well as marine flora and fauna. Spatiotemporal distribution of its culturable abundance for a range ... -
Hydrological structure and biological productivity of the tropical Indian Ocean
(NIO, Dona Paula, Goa (India), 2000)Hydrological structure analyses of regions in the tropical Atlantic Ocean have consistently revealed the existence of a typical tropical structure characterized by a nitrate-depleted mixed layer above the thermocline. The ... -
Hydrophysical manifestations of the Indian ocean tsunami
(Taylor and Francis, 2007)The horrendous destruction caused by the tsunami waves due to the earthquake in the west coast of northern Sumatra (3.307 degrees N; 95.947 degrees E) at 30 km depth with a magnitude of 9.3 on Richter scale at 00.59 UTC ... -
Hydrothermal Alteration Promotes Humic Acid Formation in Sediments: A Case Study of the Central Indian Ocean Basin
(Wiley, 2018)Anomalously high concentrations of humic?rich dissolved organic matter (DOM) in extant submarine hydrothermal vent plumes traveled far from source are increasingly being reported. This DOM, able to mobilize trace metals ... -
Hydrothermal alteration studies of gabbros from northern central Indian ridge and their geodynamic implications
(Indian Academy of Sciences, 2009)Mylonitic gabbro and altered gabbro were recovered from off-axis high and corner high locations at ridge-transform intersection, adjacent to Vityaz transform fault of the slow spreading (32-35 mm/yr, full spreading) Northern ... -
Hydrothermal amorphous silica, barite and orpiment from the crater area of seamount (SM-13) off Nicobar island, Andaman sea: Indications for the development of a new hydrothermal field
(Elsevier, 2024)The Andaman sea characterized by trench-arc-backarc elements (Andaman-Nicobar island-arc, the Andaman back-arc spreading center, the seamount complex, and the back-arc basin) is a complex active basin and is known for ... -
Hydrothermal Energy Transfer and Organic Carbon Production at the Deep Seafloor
(Frontiers, Switzerland, 2019)In just four decades, hundreds of hydrothermal vent fields have been discovered, widely distributed along tectonic plate boundaries on the ocean floor. Vent invertebrate biomass reaching up to tens of kilograms per square ... -
Hydrothermal Fe cycling and deep ocean organic carbon scavenging: Model-based evidence for significant POC supply to seafloor sediments
(Elsevier, 2015)Submarine hydrothermal venting has recently been identified to have the potential to impact ocean biogeochemistry at the global scale. This is the case because processes active in hydrothermal plumes are so vigorous that ... -
Hydrothermal minerals

Hydrothermal petroleum in the sediments of the Andaman Backarc Basin, Indian Ocean
(Elsevier, 2003)Recent sediments of he Andaman Backarc Basin, Indian Ocean, between the Andaman Nicobar islands and the Malay Peninsula have been analyzed for biomarker lipids. Three cores were selected: one each from the fault zone in a ... -
Hydrothermal plumes over the Carlsberg Ridge, Indian Ocean
(American Geophysical Union, 2012)Water column surveys and sampling in 2007 and 2009 was conducted to search for hydrothermal plumes over a segment of the Carlsberg Ridge. An evidence for two separate vent fields, one near 3 degrees 42′N, 63 degrees 40′E ... -
Hydrothermal signature in ferromanganese oxide coatings on pumice from the Central Indian Ocean Basin
(Springer, 2015)Mineralogical and elemental analyses of 20 ferromanganese (FeMn)-coated pumice samples from the Central Indian Ocean Basin (CIOB) indicate that todorokite is the major mineral phase, whereas vernadite occurs only rarely. ... -
Hydrovolcanic activity in the Central Indian Ocean Basin. Does nature mimic laboratory experiments?
(Elsevier, 1997)Classical works in the 1960's on spherules (volcanic, extraterrestrial, cosmic etc.) were carried out in order to distinguish these morphological and compositionally so as to understand their genesis yet, in some cases ... -
Hyperspectral radiometric observation of the northeast Arabians Sea during April 2006
(The Indian Society of Remote Sensing, 2008)Parameters were retrieved from the hyperspectral radiometer like upwelling and downwelling radiance (Lu and Ed) upwelling and downwelling attenuation (K-Lu and K-Ed) for 9 stations in the northeast Arabian Sea between 16-26 ... -
Hypoxia and Nutrient Reduction in the Coastal Zone: Advice for Prevention, Remediation and Research.
(Global Environment Facility, 2011)Coastal hypoxia is a complex problem and, although research has made great strides in understanding its causes and remedies, more knowledge is needed to fill critical gaps that impede action. -
Hypoxia in the changing marine environment
(IOP Publishing, 2013)The predicted future of the global marine environment, as a combined result of forcing due to climate change (e.g. warming and acidification) and other anthropogenic perturbation (e.g. eutrophication), presents a challenge ...
