Air-sea coupling during the tropical cyclones in the Indian Ocean: A case study using satellite observations
(Birkhauser Verlag, 2005)In the years 1999 and 2001,three intense tropical cyclones formed over the northern Indian Ocean - two over the Bay of Bengal during 15 -19 and 25 -29 October, 1999 and one over the Arabian Sea during 21 -28 May, 2001. We ... -
A statistical method for correcting salinity observations from autonomous profiling floats: An ARGO perspective
(American Meteorological Society, 2005)The Profiling Autonomous Lagrangian Circulation Explorer (PALACE) float is used to implement the Array for Real-Time Geostrophic Oceanography (ARGO). This study presents a statistical approach to correct salinity measurement ... -
Determination of dynamic heights in the Bay of Bengal from XBT profiles and climatological salinities
(Sears Foundation for Marine Research, 2005)Dynamic height (DH) computations are necessary for the estimation of geostrophic currents, heat transport studies, identification of eddies and to validate the altimeter sea surface height (SSH) observations. To compute ... -
Physical properties of a sediment core from the Central Indian Basin
(Indian Geophysical Union, 1998)A box core of 7.5 m was collected from the Central Indian Basin for the purpose of geotechnical studies and depthwise variation of physical properties and clay mineralogy. Water content, Atterberg limits, specific gravity ... -
Estimating the seaward extent of sea breeze from QuickSCAT scatterometry
(AGU, 2005)An objective method for quantifying the seaward extent of the sea breeze is presented. The underlying assumption is that the offshore decay in the strength of the sea breeze results in an offshore decay of the vector ... -
Tidal eddies in a semi-enclosed basin: A model study
(Elsevier, 2005)A modeling study has been carried out to support a Marine Management Plan for the Gulf of Kachchh, India and here the hydrodynamic part of the programme is described. The hydrodynamic model accurately predicts the tides ... -
Observed variability of sea surface salinity and thermal inversions in the Lakshadweep Sea during contrast monsoons
(AGU, 2005)The sea surface salinity (SSS) of the Lakshadweep Sea (LS) shows large seasonal variability due to horizontal advection of low (high) salinity waters from south (north) during winter (summer) monsoon. The measurements made ... -
Summer monsoon rainfall prediction for India - Some new ideas
(Narosa Publishing, 2005)Present methods of forecasting of mean Indian rainfall for summer monsoon season are critically examined. Considering the wide variations in mean seasonal rainfalls (more than 5 to less than 400 cm) and crops in various ... -
Dynamics and thermodynamics of the Indian Ocean warm pool in a high-resolution global general circulation model
(Elsevier, 2005)The time evolution of the Indian Ocean warm pool, studied using a global high-resolution general circulation model, shows strong seasonality. The warm pool has the largest spatial extent during April-May, and least in ... -
Circulation and mixing process in Vasishta-Godavari estuary, east coast of India
(Andhra University, 2005)Circulation and Mixing Process in Vasishta-Godavari Estuary, have been studied by using estuarine classification model. Analysis of salinity, salt budget, diffusion coefficients and flushing times based on salinity data ... -
Modelling tide-driven currents and residual eddies in the Gulf of Kachchh and their seasonal variability: A marine environmental planning perspective
(Elsevier, 2005)Tide-driven currents in the Gulf of Kachchh (GoK) have been studied using MIKE21 hydrodynamic model. The results are validated with measured currents for three different periods characterized by different wind fields. ... -
Oil spill off Goa coast - News
(Elsevier, 2005)On 23 March 2005,around 01:00 hrs an iron-ore barge Prapti collided with a Singaporean bulk carrier Maritime Wisdom, anchored about 4 nautical miles off Aguada, rupturing the carrier 's oil tank and spilling about 110 ... -

Seasonal variation in the chemical composition and carbohydrate signature compounds of biofilm
(Inter Research, 2005)Biofilm developed on stainless steel was characterised using biological, chemical and biochemical parameters, as well as aldose molecular biomarkers. Biofilm biomass and carbohydrate concentration increased on stainless ... -
Dynamics of amino acids in the conditioning film developed on glass panels immersed in the surface seawaters of Dona Paula Bay
(Taylor and Francis, 2005)The conditioning film developed on glass panels immersed in surface seawater over a period of 24 h was analysed for total organic carbon (OC), total organic nitrogen (ON), and total hydrolyzable amino acid (THAA) concentrations ... -
Quantification of diatoms in biofilms: Standardisation of methods
(Taylor and Francis, 2005)Benthic diatoms, which often dominate marine biofilms are mostly pennate along with a few centric species that have an attached mode of life. Even though the range of diatoms in biofilms is diverse, their ecology is poorly ... -
Underwater explorations of a Sangam period (300 BC-AD 400) port town at Poompuhar, east coast of India
(Aryan Books, 2005)Poompuhar, a celebrated port town of Sangam period (300 BC to 400 AD) was the capital of famous Chola dynasty during early centuries of Christian Era. Onshore explorations brought to light a few brick structures and ... -
Marine archaeological investigations along the Saurashtra coast, west coast of India
(Asiatic Society of Bangladesh, 2005)Utilization of the ocean resources on the Saurashtra coast is dating back to the Harappan period (3rd millennium BC) and evidences on the same have been recorded from various archaeological sites such as Lothal, Padri, ... -
