Denitrifying bacterial community composition changes associated with stages of denitrification in oxygen minimum zones
(Springer, 2009)Denitrification in the ocean is a major sink for fixed nitrogen in the global N budget, but the process is geographically restricted to a few oceanic regions, including three oceanic oxygen minimum zones (OMZ) and hemipelagic ... -
Effect of water quality parameters on the distribution of Pleuromamma (Copepoda-Calanoida) species in the Indian Ocean: A statistical approach
(Springer, 2009)The region between 10 degrees N and 10 degrees S latitude was known to be congenial for distribution of Pleuromamma species. Diel and ontogenetic migrations were observed for Pleuromamma xiphias. Multivariate analyses such ... -
Investigations of an intense aerosol loading during 2007 cyclone SIDR - A study using satellite data and ground measurements over Indian region
(Elsevier, 2009)Tropical cyclones are prominent weather systems characterized by high atmospheric pressure gradients and wind speeds. Intense tropical cyclones occur in India during the pre-monsoon (spring), early monsoon (early summer), ... -
Effects of copper on development and survival rate of Paphia malabarica Chemnitz larvae under low saline condition
(Springer, 2009)Venerid clam, Paphia malabarica Chemnitz, is the commercially exploited species distributed exclusively in Vembanad Lake and Ashtamudi estuary, along the south west coast of India. In this study, the survival rate and ... -
Carbonate and organic carbon content changes over last 20 ka in the Southeastern Arabian Sea: Paleoceanographic implications
(Elsevier, 2009)Two Gravity cores (AAS 38-4 and AAS 38-5) recovered from the eastern Arabian Sea were analyzed for calcium carbonate (CaCO3), organic carbon, aluminium (Al) and titanium (Ti) in order to understand the calcium carbonate ... -
Apportionment of sources affecting water quality: Case study of Kandla Creek, Gulf of Katchchh
(Taylor & Francis, 2009)This study examines a large dataset collected over various seasons of the year in Kandla Creek, Gulf of Katchchh, India, to identify and assess the contributions of the sources affecting the water quality. Principal ... -
On the role of convective systems over the northwest Pacific and monsoon activity over the Indian subcontinent
(Wiley InterScience, 2009)The association between convective systems over the northwest Pacific (NWP) and monsoon activity over the Indian subcontinent has been studied for the period 1951-2003. It was found that no systems formed over the NWP ... -
Biochemical changes during larval development in the short neck clam, Paphia malabarica Chemnitz
(Blackwell Publishing, 2009)Biochemical compositions were determined for eggs, D-shaped larvae, umbo larvae and pediveliger of the short neck clam Paphia malabarica Chemnitz. Spawned eggs were composed of 63.2% protein, 25.4% lipid and 11.4% carbohydrate. ... -
AoA Region: Red Sea And Gulf of Aden

AoA Region: South Asian Seas
(UNESCO/IOC, 2009)The South Asian Seas region lies in the northern extreme of the Indian Ocean. It includes the Arabian Sea and Bay of Bengal Large Marine Ecosystems (LME) along with their marginal basins as well as the Laccadive Sea and ... -
AoA Region: The regional organization for the protection of the marine environment/regional commission for fisheries (ROPME/RECOFI) area
(UNESCO/IOC, 2009)The ROPME/RECOFI or ROPME Sea Area includes eight countries, Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates and contains part of the Arabian Sea LME. -
Observed mixed standing-wave signatures in Cochin Estuary on the southwest coast of India
(Coastal Research Foundation, 2009)Study of the characteristics of currents and water-level variations in the Cochin estuary reveals, for the first time, unique signatures of mixed standing-waves in the southern region. Analysis of the simultaneous water-level ... -
Total synthesis of (-)- and (+)-tedanalactam
(American Chemical Society, 2009)The first stereoselective route providing access to both enantiomers of tedanalactam, a naturally occurring piperidone, has been developed. The stereogenic centers were generated by the use of Sharpless asymmetric ... -
Role of environment and hydrography in determining the picoplankton community structure of Sagami Bay, Japan
(The Oceanographic Society of Japan, 2009)Seasonal variations in the picoplankton community were investigated from June 2002 to March 2004 within the photic zone of Sagami Bay, Japan. The study area was mostly dominated by coastal waters during the warm period ... -
