Role of Diatoms in marine biofouling
(CSMCRI, India, 2006)Diatoms are one of the early colonisers on surfaces submerged in the photic zone of the environment. Their colonisation on man made structures, termed biofouling, has enormous implications in the marine industry. The ... -
Role of distinct flavours of IOD events on Indian summer monsoon
(Springer, 2016)The summer monsoon contributes to about 75 % of mean annual rainfall over the various meteorological subdivisions of India. The role of ocean–atmosphere phenomena such as Indian Ocean Dipole (IOD) and El Nino-Southern ... -
Role of eddies in structuring the mesozooplankton composition in coastal waters of the western Bay of Bengal
(2019)The mesozooplankton community structure of a cold core eddy, moving through a coastal location (Bheemunipatnam) in the western Bay of Bengal (BoB), was studied continuously for 17 days (21st February to 8th March 2016) ... -
Role of eddies in the Bay of Bengal circulation and hydrography and in the distribution of nutrients and chlorophyll
(2007)Eddies are ubiquitous in the ocean and are products of geophysical turbulence. They develop from the hydrodynamic instabilities and are known to alter the physical and biochemical properties of the ocean. In the north ... -
Role of eddies on controlling total and size-fractionated primary production in the Bay of Bengal
(Elsevier BV, 2020)In order to examine the role of eddies on total and size-fractionated primary production, two cyclonic (CE), one anticyclonic (ACE) and no-eddy (NE) regions were sampled in the BoB during pre-summer monsoon (June 2019). ... -
Role of eddies on intensity of oxygen minimum zone in the Bay of Bengal
(Elsevier, 2018)One of the strongest oxygen minimum zones (OMZ) in the world oceans occurs in the Bay of Bengal (BoB) with no systematic trends in dissolved oxygen (DO) since past half a century. An evaluation is made here to examine the ... -
Role of eddies on organic matter production and f-ratios in the Bay of Bengal
(Elsevier, 2019)In order to examine the sources of nutrients and f-ratios in the cyclonic (CE) and anticyclonic eddy (ACE), the content and isotopic composition of carbon and nitrogen in suspended particulate organic matter (POM) were ... -
Role of Effective Density in improving the accuracy of bottom pressure based sea level measurements - A case study from Gulf of Guinea
(Singapore: IEEE Singapore Section Secretariat, 2006)Seasonal observations of a set of bottom pressures and concurrent tide-staff measurements from Takoradi harbour located in the Gulf of Guinea indicated that the effective depth-mean density value, rho sub(eff) of this clear ... -
Role of environment and hydrography in determining the picoplankton community structure of Sagami Bay, Japan
(The Oceanographic Society of Japan, 2009)Seasonal variations in the picoplankton community were investigated from June 2002 to March 2004 within the photic zone of Sagami Bay, Japan. The study area was mostly dominated by coastal waters during the warm period ... -
Role of environmental heterogeneity in structuring the macrobenthic community in a tropical sandy beach, west coast of India
(Springer, 2012)In most ecosystems, community structure emerges as a result of the complex interaction between biotic and environmental variables. Sandy beaches connected to adjacent ecosystem like estuaries/creeks provide an opportunity ... -
Role of epibiotic diatoms isolated from the barnacle shell in the cyprid metamorphosis of Balanus amphitrite
(Springer International Publishing, 2018)Barnacle shell (BSh)-associated bacteria, their culture supernatants (CS), and biofilm exopolymers (BE) are known to induce cyprid metamorphosis of Balanus amphitrite. Besides bacteria, the BSh also harbors diatoms. However, ... -
Role of foraminifera in oceanographic events
(NISCAIR, CSIR, 1979)Foraminiferal studies on deep sea cores have revealed that they represent sediments from the Early Cretaceous to the Present, but the cores from the ridge areas are older in age, indicating sea floor spreading along ... -
Role of grounded ship 'MV River Princess' in triggering erosion: A case study from Candolim Sinquerim Coast, Goa.
(Centre for Earth Science Studies, 2010)Multi-temporal satellite imageries of 1997, 2001 and 2006, wave model results and field observations were used to evaluate effect of the grounded vessel MV River Princess. Erosion was triggered along the Candolim-Sinquerim ... -
Role of heavy metals in structuring the microbial community associated with particulate matter in a tropical estuary
(Elsevier, 2017)Particulate matter (PM), which are chemically and biochemically complicated particles, accommodate a plethora of microorganisms. In the present study, we report the influence of heavy metal pollution on the abundance and ... -
Role of Heterotrophic Bacteria in Marine Ecological Processes

Role of hydrology in the formation of Co-rich Mn crusts from the equatorial N Pacific, equatorial S Indian Ocean and the NE Atlantic Ocean
(The Society of Resource Geology, 2010)Co-rich Mn crusts from four different locations of the world ocean have been studied to understand the role of dissolved oxygen of the ambient seawater in the formation of Co-rich Mn crusts. WOCE (World Ocean Circulation ... -
Role of inter-annual variability in the magnitude of river discharge on CO2 fluxes in the Godavari tidal river zone, India
(Elsevier, 2023)Variations in the magnitude of river discharge may alter pH, pCO2 of surface water, and flux of CO2 to the atmosphere in the Tidal River Zone (TRZ). To test this hypothesis, a nearly decade-long time-series data of salinity, ... -
Role of iron deficiency in production and remineralization of organic matter in the Arabian Sea
(Solas, 2007)The Arabian Sea contains the only major western-boundary upwelling system in the world's oceans During summer, strong southwesterly winds bring up subsurface waters from depths of up to 200m off Somalia, Yemen and Oman ... -
Role of LAN in oceanographic information management
