Dredge spoil disposal off Kavaratti Island, Lakshadweep, India
(NISCAIR, CSIR, 1996)Maintenance dredging has been carried out along the navigational channel at Kavaratii Island and dredge spoil is disposed in the open sea. This paper describes the movement of sediment plume while dredging and disposal. ... -
Dredging of sand from a creek adjacent to a sand-spit for reclamation: Its impact on spit stability and coastal zone
(Maritime and Port Authority of Singapore, 2007)A quantity of about 17 + 10 sup(6) m sup(3) sand had been dredged from the Jatadharmohan creek (JMC) 15 km south of Paradip Port (east coast of India) in 2000, and a quantity of 14 + 10 sup(6) m sup(3) sand will be dredged ... -
Drift in salinity data from Argo profiling floats in the Sea of Japan
(American Meteorological Society, 2012)In drift analysis of salinity sensors, one major problem is the difficulty in delineating sensor drift from water mass changes. In the present study, a new method is proposed for finding sensor drift that is free from water ... -
Drift pumice in the central Indian Ocean Basin: Geochemical evidence
(Elsevier, 2008)Abundant white to light grey-coloured pumice without ferromanganese oxide coating occurs within the Quaternary sediments of the Central Indian Ocean Basin (CIOB). Two distinct groups of pumice are identified from their ... -
Drifting and meandering of Olive Ridley Sea turtles in the Bay of Bengal: Role of oceanic Rossby waves
(Taylor & Francis, 2009)Olive Ridley turtles in the Bay of Bengal are previously thought to migrate southward from their nesting ground, along the east coast of India (Orissa coast), towards Sri Lanka. Surprisingly, three of the four Platform ... -
Drivers of Future Indian Ocean Warming and Its Spatial Pattern in CMIP Models
(Wiley, 2025)Coupled Model Intercomparison Project phases 5 and 6 (CMIP5/6) projections display substantial inter-model diversity in the future tropical Indian Ocean warming magnitude and spatial pattern. Here, we investigate the ... -
Driving aspects of microplastic uptake: Influence in the Bentho-Pelagic ecosystem and its associated ecological risks along the coast of Goa, India
(Elsevier, 2025)Microplastics (MPs) interference in bentho-pelagic system plays a crucial role in understanding its impact on marine health and ensuring seafood safety. This study was an initial attempt to understand the realistic perspective ... -
Driving forces of Indian summer monsoon on Milankovitch and sub-Milankovitch time scales: A review
(Geological Society of India, 1998)A scientific consensus exists that tectonic evolution of Himalaya is the main cause of monsoon initiation and evolution in southeast Asia. Several forcing factors such as tectonic, solar insolation, latent heat transport, ... -
Dry-deposition of inorganic and organic nitrogen aerosols to the Arabian Sea: Sources, transport and biogeochemical significance in surface waters
(Elsevier, 2021)Air-to-sea deposition of water-soluble total nitrogen (WSTN) can influence the primary productivity in the coastal oceans. Here, we assessed the concentrations of aerosol inorganic (WSIN: NH4+ + NO3?) and WSTN over the ... -
Duel frequency echo data acquisition system for sea-floor classification
(Allied, India, 2005)An echo data acquisition system is designed to digitize echo signal from a single beam shipboard echo-sounder for use in sea-floor classification studies using a 12 bit analog to digital (A/D) card with a maximum sampling ... -
Duff reaction on phenols: Characterization of non steam volatile products
(Oriental Scientific Publishing Company, Bhopal, 1997)New products having structures 1 and 2 have been characterized in the Duff reaction thymol arid carvacrol. These products have been identified as 2.6'-dithymylmethane 1 and 5.5' -dicarvacryl methane 2 respectively on the ... -
Dune associated calcretes, Rhizoliths and Paleosols from the western continental shelf of India
(Geological Society of India, 1997)The calcareous deposits on the western continental shelf of India, off Bhatkal (water depths 50 to 58 m) occur as crusts, sheets, cylinders and reddish brown mudstones. The outer layers of the crusts are micrite-dominated ... -
Dust depositions leading to phytoplankton blooms in the Arabian sea.
(Solas, 2014)Atmospheric deposition of soil dust is an important source of nutrients (especially iron) to the open ocean regions. Every winter (December to March) the Arabian Sea, the northwest part of the Indian Ocean, receives large ... -
Dust-induced episodic phytoplankton blooms in the Arabian Sea during winter monsoon
(American Geophysical Union, 2014)Phytoplankton blooms mediated by the oceanic supply of nutrients is a well-understood phenomenon in the Arabian Sea (AS), while the role of dust deposition in enhancing phytoplankton is less explored. In this paper, we ... -
Dwarf foraminifera off Kerala, India: A response to mudbank formation
(Palaeontological Society of India, India, 2018)During the monsoon season, a mudbank forms off Alleppey, a coastal district in Kerala. The mudbank forms in the littoral waters within 15 m water depth. It is a small coastal zone with water being unaffected by monsoon ... -
Dynamic loadings of deepwater spar palatform - A case study
(Surathkal: National Inst of Ocean Technology, 2007)Various wave loadings are considered separately on the deepwater Spar platform, with the wave propagation along x-axis and dynamic analyses are carried out at 1150m water depth using Newmark- beta approach The dynamic ... -
