Satellite gravity anomalies and crustal features of the Central Indian Ocean Basin
(Indian Academy of Sciences, 2004)Satellite free-air gravity anomaly contour map at 5 mGal interval, seismic reflection and bathymetric data lead to the identification of deformed crustal structure of the Central Indian Ocean Basin. Twenty-three NE-SW ... -
India and the common heritage concept in the international seabed area
(Indian Academy of Sciences, 2004)The final relinquishment of 20% of the 150,000 km sup(2) under the 20 + 10 + 20% surrender arrangement has fulfilled India’s obligation towards implementing the common heritage of mankind (CHM) concept in the international ... -
Oceanographic validity of buffer zones for the east coast of India: A hydrometeorological perspective
(Indian Academy of Sciences, 2004)Relentless hydrometeorological events are the major natural hazards that have afflicted the inhabitants of the east coast. Storm surges have attained a height of 12 m, and provoked sea water invasion 35 km inland. Loss of ... -
Record decrease of sea surface temperature following the passage of a super cyclone over the Bay of Bengal
(Indian Academy of Sciences, 2004)A super cyclone with a central pressure of 912 hPa which was the lowest sofar in any tropical cyclone in Bay of Bengal, hit Paradeep coast on 29th October, 1999. The system was stationary for 30 hours after landfall and a ... -

(Indian Academy of Sciences, 2004)The 2 December 2003 refusal by Russia to ratify the 1997 Kyoto Protocol and a similar stand adopted by the U.S since March 2001 compares with the non-ratification of UNCLOS III (Third United Nations Convention on the Law ... -
A unique late bronze age copper fish-hook from Bet Dwarka Island, Gujarat, west coast of India: Evidence on the advance fishing technology in ancient India
(Indian Academy of Sciences, 2004)An onshore excavation was undertaken in Bet Dwarka Island, Gujarat, India to obtain the cultural sequence and to understand the man-sea relationship. A large number of pottery items, beads of stone, shell and terracotta ... -
Falling standards of research in India
(Indian Academy of Sciences, 2004)Some points related to falling standards of research in India are discussed. The necessity for scientists to compete by publishing in international journals of high I. F.s (Impact Factor) is stressed. India lacks pioneers ... -

Pattern of species succession of soft-bottom macrofauna in the estuaries of Goa, west coast of India
(Indian Academy of Sciences, 2003)Multivariate techniques, chord normalized expected species shared (CNESS) and principal component analyses of hypergeometric probability of species matrices (PCA-H) were applied to soft-bottom macrofauna data of Goa ... -
Aminostratigraphy of sediments of the SW Bay or Bengal
(Indian Academy of Sciences, 2003)Amino acid enantiomeric (D/L) ratio is a stratigraphic tool of Recent sediments. The method which came into being 35 years ago1, is not a precise dating tool like, for example, the radiocarbon method, as the extent of ... -
Macrobenthic abundance in the vicinity of spreading ridge environment in Central Indian Ocean
(Indian Academy of Sciences, 2003)Macrofaunal communities of the Central Indian Ocean were evaluated for their composition, distribution, abundance and biomass. The fauna comprised of 24 major groups belonging to 15 phyla. The density of macrofauna varied ... -
