Fine-scale analysis of shelf -slope physiography across the western continental margin of India
(Springer-Verlag, 2006)We attempt here to quantify and model physiographic phenomena off the central west coast of India in terms of power spectral exponent, amplitude parameter. The statistical analysis of the multibeam echosounder grid bathymetry ... -
Post-tsunami oceanographic conditions in southern Arabian Sea and Bay of Bengal
(Indian Academy of Sciences, 2006)Physical oceanographic conditions along the east and west coasts of India immediately after the recent devastating tsunami are presented here. The thermocline in the southeast coast exhibited trivial downward tilt towards ... -
Histological observations on the scleractinian coral Porites lutea affected by pink-line syndrome
(Indian Academy of Sciences, 2006)A pink-line syndrome (PLS) was reported in the reef building coral Porites lutea in Kavaratti island of the Lakshadweep archipelago. The affected corals had dead patches colonized by a cyanobacterium Phormidium valderianum ... -
Marine and estuarine methylotrophs: Their abundance, activity and identity
(Indian Academy of Sciences, 2006)Methanotrophs were up to 1 and 0.65% of the total counts in estuarine waters and offshore sediments respectively. Experimental tests on methanol utilization showed that the estuarine isolates grew best at 4% methanol whereas ... -
Exploring marine life
(NISCAIR, CSIR, 2006)Sea abounds in a variety of plant and animal life. Census of Marine Life (CoML), a global program aims to understand the diversity, geographic distribution and abundance of marine species from pole to pole covering estuarine, ... -
Programs to obtain vertical heights from mean sea level and for computing volume of sand/mineral along beaches:A case study with Kalbadevi beach profiling data and results.
(National Institute of Oceanography, Goa, 2006)Two programs have been developed to process beach profile data, for obtaining vertical heights with respect to mean sea level (M.S.L.) and for computation of volume of heavy mineral/sand accumulation or erosion along the ... -

(Indian Academy of Sciences, 2005)The First Indian Antarctic Krill Expedition (FIKEX) was an attempt to examine and obtain first-hand information pertaining to distribution, abundance and vertical migration pattern of krill –Euphausia superba Dana at fishing ... -
Anchors from Goa waters, central west coast of India: Remains of Goa's overseas trade contacts with Arabian countries and Portugal
(The Australasian Institute for Maritime Archaeology Inc, 2003)Underwater explorations have been initiated in Goa waters since 1997 for locating shipwrecks. These explorations brought to light the Indo-Arabian type of stone anchors from Sunchi Reef and Grande Island, a unique type of ... -
Historical period stone anchors from Vijaydurg on the west coast of India
(The Australian Institute for Maritime Archaeology Inc., 1998)Stone anchors are the primary antiquites in marine archaeological studies. Evidences of their evolution are noticed in India since 2500 B.C. A number of stone anchors have been recovered during the recent marine archaeological ... -
Depiction of Jagannath temple of Puri on the Portuguese paper currency
(PG Dept. of History, Berhampur University, Orissa, India, 2003)Before the introduction of metal and paper currency the medium of exchange was barter system. Over the centuries numerous types and designs of coins in various metals were issued by the rulers and kings. Paper currency was ... -

Extreme events, intrinsic landforms and humankind: Post-tsunami scenario along Nagore–Velankanni coast, Tamil Nadu, India
(Indian Academy of Sciences, 2006)Extreme oceanographic episodes have regularly afflicted the east coast of India. Storm surges strike annually, devastating for a period of 24–36 h, and inducing a run-up of 9 m and inundations reaching 35 km. Comparatively, ... -
Isotopic fractionation of boron in growing corals and its palaeoenvironmental implication
(Indian Academy of Sciences, 2006)Isotopic compositions of boron (δ11Bc value) and elemental concentrations of B, Ca, Mg, Fe and Al in growing corals from Sanya Bay, China and Kavaratti Lagoon, India along with δ11Bsw values and pH values of the coexisting ... -
Precambrian mega lineaments across the Indian sub-continent - Preliminary evidence from offshore magnetic data
(Indian Academy of Sciences, 2006)Marine and airborne magnetic data over south Indian continent including the western and eastern continental margins between latitudes 12°30`N and 10°N were studied and interpreted. The total intensity magnetic anomalies ... -
Atmospheric forcing on the seasonal variability of sea level at Cochin, southwest coast of India
(Elsevier, 2006)The seasonal cycles of some atmospheric parameters at Cochin (southwest coast of India) have been studied with a specific emphasis on the role played by them in forcing the seasonal sea level. Equatorward along-shore wind ... -
Imaging trench-line disruptions: Swath mapping of subduction zone
(Indian Academy of Sciences, 2006)Analogous to other subduction zones in the world where the heavier oceanic plate shoves below the lighter continental plate, crustal movement along the Sumatra–Andaman trench line over the last two centuries released ... -
Potential of autonomous underwater vehicles as new generation ocean data platforms
