Rare earth element distribution and behaviour in buried manganese nodules from the Central Indian Basin
(Elsevier, 1993)Eight burried manganese nodules taken in the upper metre of a siliceous ooze sediment core in the Central Indian Basin at 14 degrees S and 74 degrees E were analysed for major, trace and rare earth (REE) elements. ... -
Rare earth element geochemistry of ferromanganese deposits of the Indian Ocean
(Elsevier, 1992)Fourteen manganese nodules and three ferromanganese crusts from the Indian Ocean were analysed for major and minor elements and the 14 naturally occurring rare earth elements (REE). The REE were analysEd. by inductively ... -
Rare earth element patterns of the Central Indian Basin sediments related to their lithology
(American Geophysical Union, 1992)Rare earth element (REE) concentration have been determined in terrigenous, siliceous (nodule barren and nodule bearing), calcareous, and red clay from the Central Indian Basin. The bulk distribution of REE, and in particular ... -
Rare earth element studies of surficial sediments from the southwestern Carlsberg Ridge, Indian Ocean
(Indian Academy of Sciences, Bangalore, India, 1995)The rare earth element (REE) contents of sixteen surficial calcareous sediments from the southwestern Carlsberg Ridge, Indian Ocean, have been determined. The total REE vary from 35 ppm to 126 ppm and are inversely related ... -
Rare earth elements in suspended and bottom sediments of the Mandovi estuary,central west coast of India: Influence of mining
(Elsevier, 2011)Rare earth elements (REEs) in the suspended particulate matter (SPM) of the Mandovi estuary indicated that the mean total-REEs and light REE to heavy REE ratios are lower than that of the average suspended sediment in World ... -
Rare, metal micrometeorites from the Indian Ocean
(John Wiley & Sons, 2019)Metal in various forms is common in almost all meteorites but considerably rare among micrometeorites. We report here the discovery of two metal micrometeorites, i.e., (1) an awaruite grain similar to those found in the ... -
Rare-earth elements and uranium in phosphatic nodules from the continental margins of India
(Society for Sedimentary Geology (SEPM), Tulsa, USA, 2000)A sediment core collected from a bathymetric high off Goa on the western continental margin of India has yielded phosphatic nodules at various subsurface depths (at 110, 150, 305 355, 435, 500, 505 and 525 cm). The nodules ... -
Re-evaluation of ‘paradox of mesozooplankton’ in the eastern Arabian Sea based on ship and satellite observations
(Elsevier, 2010)In the central and eastern Arabian Sea (EAS), biomass and production of phytoplankton are known to vary spatially and seasonally whereas, biomass of mesozooplankton (MSP) is reported to be constant. This apparent contradiction ... -
Re-examination of geophysical data off Northwest India: Implications to the Late Cretaceous plate tectonics between India and Africa.
(Elsevier, 2015)The Gop and Laxmi Basins lying off Northwest India have been assigned ambiguous crustal types and evolution mechanisms. The Chagos-Laccadive Ridge (CLR) complex lying along the southwest coast of India has been attributed ... -
Re-introduction and supplementation of species of Acropora and Pocillopora into the lagoons of Lakshadweep Islands, India
(Abu Dhabi: IUCN/SSC Re-introduction Specialist Group, 2008)The genera Acropora and Pocillopora are represented by a large number of species in most coral reefs They are more sensitive to environmental changes and anthropogenic effects and hence are more at risk than other coral ... -
Reaction of Elemol with Acetic acid –Perchloric acid: Characterization of a novel oxide and (+)-β-cyperone
(Springer-Verlag, 2006)The minor unidentified compounds of acetic acid- perchloric acid dehydration of elemol (1) have been fully characterized. The structure and relative stereochemistry as shown in (2) of the less polar fragrant compound named ... -
Reactivation of precambrian faults on the southwestern continental margin of India: Evidence from gravity anomalies
(Elsevier, 1993)Gravimetric and bathymetric studies on the southwestern continental margin of India confirm the extension of onshore NW-SE-, NNW-SSE-, N-S-, NE-SW-, ENE-WSW- and E-W-trending lineaments of Precambrian age over a considerable ... -

Real time Aanderaa current meter data collection system
(NISCAIR, New Delhi, 1993)Aanderaa current meters are widely used for recording the current speed and such other 4 parameters by deploying them over extended period of time. Normally data are recorded on magnetic tape and after recovery of current ... -
Real Time PCR detection of Macrobrachium rosenbergii (de Man, 1879) larvae with emphasis to their ecology
(EDP Sciences, 2021)Species specific identification of early larval stages of many decapod crustaceans sampled from plankton collections remains cumbersome owing to lack of distinguishable characteristics, where DNA based molecular methods ... -
Real time wave measurements and wave hindcasting in deep waters
(CSIR-NISCAIR, 1994)Deep water waves off Karwar (lat. 14~'45.1'N, long. 73~'34.8'E) at 75 m water depth pertaining to peak monsoon period have been measured using a Datawell waverider buoy. Measured wave data show that the significant wave ... -
