Use of shallow seismic surveys in the exploration of nearshore placers off Maharashtra coast, India
(1988)Shallow seismic surveys were carried out for 520 lkm in 3 bays viz., Jaigad, Ambwah and Varwada along the Maharashtra coast in the western part of India. In total, 53 traverses were run across the shelf perpendicular to ... -
Use of Slaughter House Waste as a Feed for Shrimps and Prawns
(CSIR-NISCAIR, 1981)Feeding experiments with some shrimps and fishes (Metapenaeus monoceros, Metapenaeus dobsoni, Sarotherodon mossambicus and Etroplus suratensis) using slaughter house waste as food, showed that the shrimps and arotherodon ... -
Use of sparker signal to classify seafloor sediment
(Publ. and Inf. Dir., New Delhi, India, 1994)During the cruise 190 of R.V. Gaveshani, the sparker signal was recorded in the analog form on audio cassettes. This signal has been digitized and a statistical computation, viz. the normalized cross-correlation function ... -
Use of swath data in realtime navigation by pattern recognition
(Elsevier, 1989)A new method is proposed with the aim of reducing dead reckoning error (DRE) during multibeam echosounding survey in deep ocean. Bathymetric data is used in this method to estimate DRE in position fixing. This method can ... -
Use of the Boron partition coefficient ‘K<sub>D</sub>’ and B/Ca from planktonic foraminifera in the estimation of past seawater pCO<sub>2</sub>
(Geochemical Society of Japan, 2015)We assess the usefulness of the empirical boron partition coefficient, K<sub>D</sub> and B/Ca measured from planktonic foraminifera in estimation of pCO<sub>2</sub> using three different relationships between K<sub>D</sub> ... -
Use of timber in shipbuilding industry: Identification and analysis of timber from shipwrecks off Goa coast, India
(Indian Academy of Scinces, 2005)The use of timber in the boatbuilding or shipbuilding industry is as old as the construction of boats and ships. Various kinds of timber are used in different regions of India in the construction of vessels. The Yuktikalpataru ... -
Use of wood charcoal powder in quick drying of fish by heat radiation
(Bhavnagar: Central Salt and Marine Chemicals Research Institute, 1978) -
Using multi-spectral remote sensing for flood mapping: A case study in lake Vembanad, India
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Water is an essential natural resource, but increasingly water also forms a threat to the human population, with floods being the most common natural disaster worldwide. Earth Observation has the potential for developing ... -
Using remote sensing and gis techniques for detecting land cover changes of mangrove habitats in Goa, India
(Sana’a University, 2014)Ecologically Sensitive Marine Habitats (ESMH), including mangroves ecosystems, is of immense ecological and socioeconomic values. Goa, a tourist destination, has limited cover of such habitats and has been intensively ... -
Utility of natural generalised inverse technique in the interpretation of dyke structures
(NISCAIR, CSIR, 2005)Forward and Inverse methods of magnetic interpretation have been used to estimate the parameters of dyke like intrusion over the eastern continental shelf of India. In the forward problem, the tentative parameters of the ... -
Utilization of adult burrows by juveniles of the ghost shrimp, Callianassa japonica Ortmann: evidence from resin casts of burrows
(Carcinological Society of Japan, 1992) -
Utilization of high resolution satellite geoid data for estimation of lithospheric thickness in the Bay of Bengal
(NISCAIR, CSIR, 2009)Very high-resolution database generated from Seasat, Geosat GM, ERS-1 and TOPEX/ POSEIDON altimeters data of the northern Indian Ocean has been used for the first time for preparation of geoid and free-air gravity maps. ... -
Utilization of nitrate and phosphate by the green alga Tetraselmis gracilis Kylin

UV radiation and natural fluorescence linked primary production in Antarctic waters
(Marine Biological Association of India, 2001)Primary productivity and chlorophyll values have been measured using an underwater profiling radiometer for the first time in the waters around Indian Antarctic Station (70°46'S & 11°44'E) in the summer of 1994. The profiles ... -
UV radiation and primary production in the Antarctic waters
(Department of Ocean Development, New Delhi, 1997)A profiling underwater radiometer was used for the first time in the waters around Indian Antarctic Station (70 degrees 46 minutes S and 11 degrees 44 minutes E) in the summer of 1994. The profiles include natural fluorescence ... -
UV-absorbing bacteria in coral mucus and their response to simulated temperature elevations
(Springer, 2013)Reef-building corals encompass various strategies to defend against harmful ultraviolet (UV) radiation. Coral mucus contains UV-absorbing compounds and has rich prokaryotic diversity associated with it. In this study, we ... -
Validation of argo data in the Indian Ocean
(Universidad de Concepcion, 2004)ARGO-salinity data from the Indian Ocean are validated using salinity from float-versus-float match-ups and also using CTD observations from three cruises. Validation data sets are selected in such a way that the float and ... -
Validation of EIA sampling methods - bacterial and biochemical analysis
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)Deep sea sediments from Central Indian Ocean Basin (CIOB) were sampled from 10 degrees .00'-10 degrees .10'S latitude and 75 degrees .55'-76 degrees .05'E longitude for assessing the potential environmental impact of ... -
Validation of ERS-1 and high-resolution satellite gravity with in-situ shipborne gravity over the Indian offshore regions: Accuracies and implications to subsurface modeling
