Role of riverine inputs, low saline plume advection and mesoscale physical processes in structuring the Chlorophyll a distribution in the western Bay of Bengal during Fall Inter Monsoon
(Elsevier, 2021)This study delineates the role of small and medium river inputs, Low Saline Plume Advection (LSPA) and eddies in hydrography alteration and Chlorophyll a (Chl. a) in the Western Bay of Bengal. Samples were collected across ... -
Role of rotifers in microzooplankton community in a large monsoonal estuary (Cochin backwaters) along the west coast of India
(Springer International Publishing, 2018)The distribution ecology of microzooplankton in the Kochi (Cochin) backwaters has been presented. Emphasis has been given to the micro-rotifers present in the environment, considering they were a hitherto ignored component ... -
Role of salinity in structuring the intertidal meiofauna of a tropical estuarine beach: Field evidence
(NISCAIR, CSIR, 1998)Community structure of meiofauna was studied for 12 months (July 1991-June 1992) on an estuarine intertidal beach at Siridao, Goa (India). The temperature of the surf zone water ranged from 26.5 degrees to 30.7 degrees C; ... -
Role of salinity on food conversion efficiency and growth in juvenile penaeid shrimp Metapenaeus dobsoni (Crustacea/Arthropoda)
(NISCAIR, CSIR, 1997)Growth parameters of juvenile Metapenaeus dobsoni, fed with fresh squid meat were estimated in 5, 15, 25 and 35 ppt salinities for 4 weeks. Although no significant differences were noticed in food ingestion rates, higher ... -
Role of salinity on zooplankton assemblages in the tropical Indian estuaries during post monsoon
(Elsevier, 2023)The estuary is the transition zone between the riverine and marine environments, in which the zooplankton act as a trophic connector in the energy transfers from primary producers to secondary consumers. Zooplankton biovolume ... -
Role of sediment particles in mining of polymetallic nodules in the Central Indian Ocean

Role of shamal and easterly winds on the wave characteristics off Qatar, central Arabian Gulf
(Elsevier, 2021)Waves in the Arabian Gulf (Gulf) are dominated by shamal winds during winter and early summer. Although wave characteristics in the Gulf are broadly studied, features associated with various wind systems are not explicitly ... -
Role of subsurface layer temperature inversion in cyclone induced warming in the northern Bay of Bengal
(Elsevier, 2023)Subsurface Layer Temperature Inversion (SLTI) is a prominent physical process occurring in the Bay of Bengal (BoB) during winter. BoB also witnesses intense cyclones during winter (post-monsoon). Sidr is a category-5 cyclone ... -
Role of sulfur-oxidizing bacteria on the ecology in tropical mangrove sediments
(Elsevier, 2019)Mangroves are unique ecological niches for microorganisms which play major roles in biogeochemical cycles and in nutrient recycling. Sulfur compounds are primarily utilized by sulfur-oxidizing bacteria (SOB) and sulfate-reducing ... -
Role of teak and other hardwoods in shipbuilding as evidenced from literature and shipwrecks
(Current Science Association, 2016)One of the greatest achievements of man is the invention of watercraft which has been used from the prehistoric period onwards. Over the centuries, varieties of watercraft were designed and developed. Timber was the main ... -
Role of the Indian Ocean on the southern oscillation, atmospheric circulation indices and monsoon rainfall over India
(Taylor and Francis, 1999)The relationship between the sea surface temperature (SST) in a small region (0-5 N; 80-85 E) in the Eastern Equatorial Indian Ocean and Indian monsoon rainfall and monsoon Indices (M1, U200) has been examined. The role ... -
Role of time series sediment traps in understanding the Indian summer monsoon
(National Institute of Oceanography, India, 2007) -
Role of upper ocean parameters in the genesis, intensification and tracks of cyclones over the Bay of Bengal
(Institute of Marine Engineering, Science & Technology, 2015)It is well known that the frequency of cyclones is about four times higher over the Bay of Bengal when compared with the Arabian Sea. Most of the severe cyclones during pre-monsoon (April and May) and post-monsoon (October ... -

Roles of upwelling and riverine influx on the summer phytoplankton bloom in the Western Bay of Bengal
(Elsevier, 2023)The Bay of Bengal (BoB) is generally considered a low-productive region. However, several phytoplankton blooms (high Chlorophyll a) are frequently reported, including the one observed between Kakinada (KKD) and Visakhapatnam ... -
Roseovarius azorensis sp. nov., isolated from seawater at Espalamaca, Azores
(Springer, 2014)A Gram-negative, motile, non-spore forming, rod shaped aerobic bacterium, designated strain SSW084<sup>T</sup>, was isolated from a surface seawater sample collected at Espalamaca (38°33`N; 28°39`W), Azores. Growth was ... -

Run-up and inundation limits along southeast coast of India during the 26 December 2004 Indian Ocean tsunami
(Indian Academy of Sciences, 2005)The recent Indian Ocean Tsunami had a devastating effect on the Indian coastline. Apart from the Andaman and Nicobar Islands, the Tamil Nadu coast was the most affected. Post-Tsunami survey was carried out during ... -
Ruthenium(II)-catalyzed synthesis of 2-arylbenzimidazole and 2-arylbenzothiazole in water
(Springer, 2021)Benzimidazoles/benzothiazoles are heterocyclic compounds which contain a five membered heteroatom and a benzene ring. They constitute a crucial structural unit of numerous bioactive compounds and natural products. Since ... -
Ruthenium(II)-catalyzed synthesis of pyrrole- and indole-fused isocoumarins by C-H bond activation in DMF and water
(Wiley, 2016)Pyrrole- and indole-fused isocoumarins constitute important structural units in natural products and pharmacophores, although the direct and selective bifunctionalization of pyrrole and indole remain a challenge. Herein, ...
