Stone anchors from the Okhamandal region, Gujarat Coast, India
(Academic Press, 1999)During marine archaeological explorations since 1983, off Dwarka, a large number of stone anchors were discovered and dated to 1400 BC, comparing with anchors found in Mediterranean waters. In recent archaeological ... -
Marine investigations in the Lakshadweep Islands, India
(Antiquity Trust, 1999)The Lakshadweep Islands lie on the sea route between West Asia and Africa on the one hand and South Asia and the Far East on the other. In maritime history, these islands have played a vital role by providing shelter, fresh ... -
Ancient shorelines of Gujarat, India, during the Indus civilization (Late Mid-Holocene): A study based on archaeological evidences
(Current Science Association, Bangalore, India, 1999)Changes in the shoreline at any point could be due to various reasons such as tectonic disturbance or shift in sedimentological regime causing erosion or deposition. Many scientific investigations, focussing on the ... -
Studies on mixing of the waters of different salinity gradients using Richardsons number and the suspended sediment distribution in the Beypore Estuary, south west coast of India
(Council of Scientific and Industrial Research, New Delhi, 1999)The study was conducted up to 15 km upstream in the Beypore Estuary of the Chaliyar River in Calicut. The study area was divided into four sections (5 km interval) with two transverse stations on either side of each section. ... -
Time and space variations of monsoonal upwelling along the west and east coasts of India
(Pergamon, 1999)The study of monthly mean local temperature anomaley (LTA defined as the difference between coastal and mid-ocean sea surface temperature), and Ekman transport along the west and east coasts of India based on 60-year data ... -
Excess aluminum in deep sea sediments of the Central Indian Basin
(Elsevier, 1999)The aluminum concentration in the marine sediments has long been considered an indicator of terrigenous abundance. The Al/Ti values (48.5) of the Central Indian Basin subsurface siliceous sediment are up to three times ... -
Evolution of the basalts from three back-arc basins of southwest Pacific
(Springer, 1999)Petrography, petrochemistry, and mineral chemistry of basalts from the Woodlark, Manus, and Lau basins from the southwest Pacific have been studied to understand their magmatic evolution. Basalt from the western Woodlark ... -
Tectonics of the Bay of Bengal: New insights from satellite-gravity and ship-borne geophysical data
(Elsevier, 1999)Recently released satellite-derived free air gravity anomalies and the existing ship-board geophysical data provide new insights into the tectonics of the Bay of Bengal with respect to the structure and regional extension ... -
Distribution of organic carbon in surface sediments along the eastern Arabian Sea: a revisit
(Elsevier, 1999)One hundred twelve surface sediment samples along the western continental margin of India were analyzed for organic carbon (OC). Elevated OC concentrations are associated with sediments deposited in areas where producitivity ... -
Leg 179 summary
(ODP, Texas A and M Univ., USA, 1999)Ocean Drilling Program (ODP) Leg 179 set out with two primary objectives. These objectives were (1) testing the recently developed hammer drill-in casing system on the Atlantis Bank, Southwest Indian Ridge (SWIR), and (2) ... -
Opportunities for offshore mineral exploration in the Indian Ocean
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)The Indian Ocean offers several opportunities for offshore mineral resources in the nearshore and coastal areas, the EEZs of different countries as well as the deep sea regions. The coastal and nearshore resources of heavy ... -
Influence of sedimentation on enrichment of manganese and growth of ferromanganese micronodules, Bengal Fan, India
(Elsevier, 1999)Based upon down core variations in O/Mn ratio in sediment and in micronodules, Mn content, organic carbon and abundance of micronodules in two box cores from high and low sedimentation regions of the Bay of Bengal, 0-20 ... -
An assessment of seabed conditions for port development: A case study of Nagore - east coast of India
(Oxford and IBH, New Delhi, 1999)The knowledge of the seabed engineering parameters is a pre-requisite for any meaningful attempt to evolve plans and strategies for port developments. The close track spacing (50-100 m) of data sets on bathymetry, sub-bottom ... -
Alteration of basaltic glasses from the Central Indian Ocean
(Geological Society of India, 1999)Textural, mineralogical and compositional characteristics of basaltic glasses from the Central Indian Ocean show them to be altered to varying extents through their interaction with the seawater, resulting in the formation ... -
A review on Holocene climate changes in Indian subcontinent
(Geological Society of India, 1999)Since the collision of Indian plate with Eurasia, the Indian subcontinent has experienced minor tectonic and major climatic changes. Summer monsoon plays an important role in the local and regional climate of Asia. General ... -
