Seasonal variability of sea-surface temperature fronts associated with large marine ecosystems in the north Indian Ocean
(Springer India, 2019)
We use 14 years of satellite-derived sea-surface temperature (SST) data to compute a monthly frontal probability index (FPI) to determine the existence of a front in a pixel. A persistent SST front is deemed to exist if ...
The economics of mining seabed manganese nodules: A case study of the Indian Ocean nodule field
(Taylor and Francis Ltd., 2019)
Because of ever-growing demand for strategic metals, the focus of the international community has fallen on deep sea manganese nodules occurring at a water depth of more than 4500 m. We present an economic appraisal and ...
Arikamedu: A Indo-Roman Trading Station - Revisited
(Indian Society for Prehistoric and Quarternary Studies (ISPQS), 2017)
Arikamedu is one of the most important early historic ports on the East Coast of India. Arikamedu excavations and explorations have shown evidence of maritime contacts between India and the Roman and Southeast Asian countries ...
Source analysis of radiocesium in river waters using road dust tracers
(Pergamon, 2017)
Following the Fukushima Dai-ichi Nuclear Power Station accident, regional road dust, heavily contaminated with radiocesium, now represents a potential source of radiocesium pollution in river water. To promote effective ...
Interannual and long-term sea level variability in the eastern Indian Ocean and South China Sea
(Springer Berlin Heidelberg, 2018)
Sea level anomalies (SLAs) derived from satellite observations (over a period of 22 years) and tide gauge data compiled from 66 stations from the eastern Indian Ocean and South China Sea (SCS) and western Pacific Ocean ...
Aragonite pteropod abundance and preservation records from the Maldives, equatorial Indian Ocean: Inferences on past oceanic carbonate saturation and dissolution events
(2019)
During the International Ocean Discovery Program (IODP) Expedition 359, a long continuous carbonate-rich sequence was recovered from the Inner Sea of Maldives. We investigated pteropod proxies (absolute abundance of pteropods ...
Suspended sediment dynamics in Cochin estuary, West coast, India
(Springer, 2017)
An observational study was conducted in Cochin estuary to examine the relative impacts of tidal and river runoff forcing upon suspended sediment dynamics at different time scales. Time series measurements of salinity and ...
Maritime archaeology of Lakshadweep Islands, India
(Indian Archaeological Society, 2012)
Lakshadweep Islands lie on the sea route between South Asia, Far East and African countries Boats and ships used the islands of Lakshadweep as a stopover to take on fresh water The Islands of Lakshadweep played a significant ...
Polycyclic Aromatic Hydrocarbons (PAHs) and Hopanes in Plastic Resin Pellets as Markers of Oil Pollution via International Pellet Watch Monitoring
(Springer, 2017)
Oil pollution in the marine environment is an unavoidable problem due to chronic input from local sources, particularly in urban areas and oil spills. Oil pollution not only causes immediate physical damages to surrounding ...
Geochemical, mineralogical, and Sr-Nd isotopic compositions of ferromanganese encrustations from Central Indian Ridge at 06�38.5-S
(John Wiley & Sons, 2018)
Mineralogical, geochemical, and isotopic (Sr and Nd) studies of 14 ferromanganese encrustations on basaltic substrates from Central Indian Ridge at 06�38.5-S indicate that except for two (NC3 and NC4), the samples are ...
