An Indo-Arabian type of stone anchor from Kannur, Kerala,west coast of India
(Blackwell Synergy, 2005)A great deal of new evidence relating to maritime archaeology of India has come to lime light in the recent years, both from explorations and excavations. Among them the ancient stone anchors are the key to understand ... -
Ships on hero stones from the west coast of India
(Blackwell Synergy, 2006)Hero stones have been erected since early times to remember those who died in battle, and have been reported from various provinces of India. Most show land-battles, but those in the Archaeological Museum, Goa (India) and ... -
Study of high-resolution satellite geoid and gravity anomaly data over the Bay of Bengal
(Indian Academy of Sciences, 2006)Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geo-scientific investigations. Very high-resolution gravity database generated from Seasat, Geosat GM, ERS-1 and ... -
Cellular-based sea level gauge
(The Hindu, 2006)The National Institute of Oceanography has developed a coastal sea-level monitoring system that can be accessed on the Internet. -
Climate induced changes in the circulation and dispersal patterns of the fluvial sources during late Quaternary in the middle Bengal Fan
(Indian Academy of Sciences, 2006)From a transact along 15˚N latitude in the middle Bengal Fan, temporal and spatial variations in the granulometric parameters and clay minerals in 14C dated box cores from the eastern, the central and the western regions ... -
Formation of genotoxic nitroPAH compounds in fish exposed to ambient nitrite and PAH
(Oxford University Press, 2006)Mutagenic nitrated polycyclic aromatic hydrocarbons (nitroPAHs) have been known to arise in the environment through direct emissions from combustion sources and nitration of PAHs, primarily in the atmosphere. Here we report ... -
Diversity and adaptations of deep-sea microorganisms
(I.K. International, New Delhi, 2005)The discovery of near fresh closed lunch box found after 11 months in the wreck of the submersible Alvin in the year 1969 opened up a Pandora’s box of microbial diversity in the deep-sea. Discovery that near-freezing ... -
Biological deinking of inkjet-printed paper using Vibrio alginolyticus and its enzymes
(Society for Industrial Microbiology, 2005)Recycling of office waste paper (photocopy, inkjet and laser prints) is a major problem due to difficulty in removal of non-impact ink. Biological deinking of office waste paper is reported using several microorganisms and ... -
Stress response of two coral species in the Kavaratti atoll of the Lakshadweep Archipelago, India
(Springer-Verlag, 2005)Frequent occurrences of coral bleaching and the ensuing damage to coral reefs have generated interest in documenting stress responses that precede bleaching.. The objective of this study was to assess and compare physiological ... -
Enhanced production of laccase by a marine fungus during treatment of colored effluents and synthetic dyes
(Elsevier, 2006)Paper and pulp mills, textile and dye-making industries and alcohol distilleries release highly colored effluents that are relatively difficult to decolorize by chemical and physical treatments. White-rot basidiomycetous ... -
Fungi in deep-sea sediments of the Central Indian Basin
(Elsevier, 2006)Although a great amount of information is available on bacteria inhabiting deep-sea sediments, the occurrence of fungi in this environment has been poorly studied and documented. We report here the occurrence of fungi in ... -
Marine Bioinvasion: An Overview
(National Institute of Oceanography, Goa, 2002)Shipping is the backbone of global economy and facilitates transportation of 90% of commodities. A single bulk cargo ship of 200,000 tones can carry up to 60,000 tones of ballast water. It is estimated that 12 billion tones ... -
Recruitment of the barnacle Balanus amphitrite Darwin in a tropical estuary: implications of environmental perturbation, reproduction and larval ecology
(Cambridge University Press, 2005)Phytoplankton blooms are known to influence barnacle recruitment and in boreal regions spring blooms work as an important trigger. Close to the west coast of the sub-continent of India, blooms tend to be triggered by breaks ... -
Studies on ecology of diatoms
(2003)Diatoms are abundant in the phytoplankton and phytobenthos of aquatic ecosystems, whatever the latitude. Within the aquatic realm, diatoms further extend their habitats from the pelagic to benthic environment and are also ... -
Reproduction in Balanus amphitrite Darwin (Cirripedia: Thoracica); influence of temperature and food concentration
(Springer, 2006)Balanus amphitrite, an acorn barnacle is distinctly euryhaline and eurythermal, and a dominant fouling organism found in warm and temperate waters through out the world. In this study the influence of temperature and food ... -
Seasonal beach profiling along Malvan and Kotharwadi coast , southern Maharashtra, central west coast of India.
(National Institute of Oceanography, Goa., 2006)Seasonal morphological variations and effect of oceanographic processes such as erosion or accretion along beaches are important to understand the nature of the beach and the cyclic changes occurring during different ... -
Studies on some cues regulating metamorphosis of the larvae of Balanus amphitrite (Cirripedia: Thoracica)
(2002)Recruitment of the larvae of fouling organisms and their metamorphosis is the most important step in the fouling process. Cypris larvae does a substratum search before undergoing metamorphosis. The third antennular segment ... -
Studies on some ecological aspects of Balanus amphitrite (Cirripedia: Thoracica)
(2002)The year round breeding capability of Balanus amphitrite indicates a potential for continuous recruitment. The recruitment pattern however indicated a lull during monsoon. The study site experiences increased land run off ... -
Eco-biology of marine diatoms with emphasis on the influence of physico-chemical parameters
(2003)Diatoms constitute an important part of the microphytobenthic community in the intertidal sand flat. Intertidal sandflats are dynamic environments, where the tidally generated water movement and the associated processes ... -
Xylanases of marine fungi of potential use for biobleaching of paper pulp
(Society for Industrial Microbiology, 2004)Microbial xylanases that are thermostable, active at alkaline pH and cellulasefree are generally preferred for biobleaching of paper pulp.. We screened obligate and facultative marine fungi for xylanase activity with these ...
