Review of Mining Rates, Environmental Impacts, Metal Values, and Investments for Polymetallic Nodule Mining
(2019)This chapter reviews different mining rates for polymetallic nodules and evaluates the ensuing environmental impacts as well as metal production with respect to land reserves, metal prices, and projected investments. It ... -
Review of previous geophysical and geological studies
(Geological Society of India, Bangalore, India, 1998) -
Reviews and syntheses: Anthropogenic perturbations to carbon fluxes in Asian river systems - concepts, emerging trends, and research challenges
(European Geosciences Union, 2018)Human activities are drastically altering water and material flows in river systems across Asia. These anthropogenic perturbations have rarely been linked to the carbon (C) fluxes of Asian rivers that may account for up ... -
Reviews and syntheses: Physical and biogeochemical processes associated with upwelling in the Indian Ocean
(Copernicus GmbH, 2021)The Indian Ocean presents two distinct climate regimes. The north Indian Ocean is dominated by the monsoons, whereas the seasonal reversal is less pronounced in the south. The prevailing wind pattern produces upwelling ... -
Revisiting the Biostratigraphic Range and Possible Cause of the First and Last Occurrence of Globigerinoides Ruber (Pink) in the Northern Indian Ocean
(The Cushman Foundation for Foraminiferal Research, Kansas, USA, 2023)The first and last occurrence datums of species are often used as biostratigraphic markers to establish chronology beyond the range of radiocarbon dating. One such datum, the last occurrence of Globigerinoides ruber (pink) ... -
Revisiting the structure, age, and evolution of the Wharton Basin to better understand subduction under Indonesia.
(American Geophysical Union, 2014)Understanding the subduction processes along the Sunda Trench requires detailed constraints on the subducting lithosphere. We build a detailed tectonic map of the Wharton Basin based on reinterpretation of satellite-derived ... -
Rhodovulum mangrovi sp. nov., a phototrophic alphaproteobacterium isolated from a mangrove forest sediment sample
(International Union of Microbiological Societies, 2014)A novel Gram-staining-negative, purple non-sulfur bacterium, strain AK41T, was isolated from a sediment sample collected from Coringa mangrove forest, Andhra Pradesh, India. A red–brownish-coloured culture was obtained on ... -
Rhopalophthalmus constrictus sp. nov. and Australomysis reubeni sp. nov. (Crustacea-Mysidacea) from south-west Australian waters
(Cambridge University Press, 1992)Two new species of mysids are described, Rhopalophthalmus constrictus sp. nov. is in having a well-produced triangular rostral plate, pleural plates on the anterior five abdominal somites and prominent constriction at the ... -
Rice husk as a potential source of silicate to oceanic phytoplankton
(Elsevier, 2023)Global oceans are witnessing changes in the phytoplankton community composition due to various environmental stressors such as rising temperature, stratification, nutrient limitation, and ocean acidification. The Arabian ... -
Richardson Number, stability and turbulence- A coherent view
(NISCAIR, CSIR, 1996)As turbulence in water is governed by vertical mobility controlled by static stability and horizontal mobility controlled by currents, the Richardson Number should give a measure of turbulence also. It is argued in this ... -
Ringstone anchors from Gujarat, west coast of India
(The Society for Nautical Research, 2002)The Gujarat coast, India has played a vital role in the maritime activities of India from the beginning of the Indus civilization in the Indian subcontinent and has witnessed hectic maritime activity since then. Offshore ... -

Rip current occurrences in meso tidal surf zones at a coastal stretch along the central west coast of India
(Elsevier, 2022)Currents in the surfzone were measured and modeled along a coastal stretch on the central west coast of India. Wave and tide were the primary forcings for the numerical model, which was validated with the measurements. The ... -
RIP current zones along beaches in Goa, west coast of India
(American Society of Civil Engineers, 1997)Goa has a 125-km-long coastline of which two-thirds consists of beautiful sandy beaches. There are mainly 17 beaches having significant importance of tourism. Sporadically, surf drownings have been reported at a few stretches ... -

Rise of the dormant: Simulated disturbance improves culturable abundance, diversity, and functions of deep-sea bacteria of Central Indian Ocean Basin
(Taylor and Francis, 2005)The abundance of baroduric bacteria from nine sediment cores (0-10 cm below sea floor) was examined for their response to simulated benthic disturbance in the Central Indian basin (CIB). While the total counts of bacteria ... -
Risk assessment of polycyclic aromatic hydrocarbon infested sediments along the coast of Goa, India
(Springer, 2023)Goa, a small state in India, is a tourist hotspot known for its coastline and beaches. Anthropogenic activities lead to pollution in the environment. Amongst many other pollutants, polycyclic aromatic hydrocarbons represent ... -
Risk assessments of microplastics accumulated in estuarine sediments at Cuddalore, Tamil Nadu, southeast coast of India
(Springer, 2023)In this study, the abundance of microplastics (MPs) in the Uppanar and Gadilam estuaries in Cuddalore, on the southeast coast of India, is reported. In the estuarine sediments, MP abundance ranged from 36.3 ± 3.39 to ... -
