Physiological and molecular studies of deep-sea fungi
(2011)The objectives of the present study were to isolate and identify fungi from deep-sea sediments of the Central Indian Basin (CIB) using culture-dependent as well as culture-independent approaches by molecular methods. ... -
Excavations at Kanjetar and Kaj on the Saurashtra Coast, Gujarat
(Journal of the Indian Society for Prehistoric and Quarternary Studies, 2011)Onshore excavations were undertaken at Kanjetar and Kaj around Kodinar in Gujarat. Kanjetar is located about 12 km southwest of Kodinar on the coastal region. This is a single culture site of the Harappan phase. The entire ... -
An evaluation of major placer minerals along the Valinokkam - Tuticorin coast, southern Tamil Nadu, India
(Cafet-Innova Technical Society, 2011-12)The present investigation aims to understand the reserve of major placer minerals like garnet, ilmenite, zircon and magnetite from the beaches of Valinokkam-Tuticorin, Southern Tamil Nadu. The availability of garnet in the ... -
Acetylcholinesterase activity in marine gastropods as biomarker of neurotoxic contaminants
(Mudrakar and Institute of Ecotoxicology and Environmental Sciences, 2011)The acetylcholinesterase (AchE) activity was measured in three different species of marine gastropods namely Cronia contracta, Morula granulata and Planaxis sulcatus collected from selected stations (Arambol, Anjuna, Dona ... -
Ancient anchorage systems in India with reference to the Gujarat coast
(Darshak Itihas Nidhi, 2011)The Indian coast, with a long history of maritime activities, has been dotted with several ancient ports. The evidence for this exists in port-related structures on the shore and in relics lying in the sea adjacent. Marine ... -
Maritime archaeology of the Okhamandal region, Gujarat
(Darshak Itihas Nidhi, 2011)The Maritime Archaeological studies in India were initiated in Okhamandal region and Dwarka and Bet Dwarka were the prime sites for the early investigations. The region remained for focal point of the study for almost over ... -
Archaeological sites along the Gujarat coast: Proxies to decipher the past shoreline
(Darshak Itihas Nidhi, 2011)During the late Holocene, coastal configuration has undergone continuous changes due to various reasons like sea level fluctuations and shoreline shift. Several reasons are attributed like global warming causing polar ice ... -
Preliminary assessment of an early historic (2000 year old) shipwreck at Godawaya, Sri Lanka
(Australasian Institute for Maritime Archaeology, 2011)An international team comprised of experts in diving and underwater archaeology from Sri Lanka, India, Indonesia, Malaysia and Philippines participated in the assessment of the shipwreck at Godawaya, Sri Lanka. The main ... -
Identification of non-indigenous phytoplankton species dominated bloom off Goa using inverted microscopy and pigment (HPLC) analysis
(Indian Academy of Sciences, 2011-12)An unusual phytoplankton bloom dominated by unidentified green coloured spherical algal cells (approx 5 mu m diameter) and dinoflagellates (Heterocapsa, Scripsiella and Gymnodinium) was encountered along the coast of Goa, ... -
Observed interannual variability of the thermohaline structure in the south eastern Arabian Sea
(Springer, 2011)The XBT and sea surface salinity (SSS) measurements systematically carried out at near-fortnightly interval from May 2002 to August 2008 in the South Eastern Arabian Sea (SEAS) are utilised to describe the observed seasonal ... -
Measurement of DNA integrity in marine gastropods as biomarker of genotoxicity
(Mudrakar and Institute of Ecotoxicology and Environmental Sciences, 2011)The occurrence of DNA strand breaks in marine gastropods such as Nerita chameleon, Morula granulata and Cerithidea cingulata collected from different sites (Tirakol, Arambol, Dona Paula and Velsao) along the Goa coast are ... -
Assessment of the impact of xenobiotic pollutants on the marine organisms: Molecular biomarker approach
(Mudrakar and Institute of Ecotoxicology and Environmental Sciences, 2011)The contamination of the marine environment by xenobiotic compounds such as poly aromatic hydrocarbons (PAHs), persistent organic pollutants (POPs), polychlorinated biphenyls (PCBs), organochlorine (OC) pesticides, heavy ... -
Measuring and monitoring eutrophication and hypoxia
(Global Environment Facility, Washington, 2011)Coastal hypoxia is a complex problem and, although research has made great strides in understanding its causes and remedies, more knowledge is needed to fill critical gaps that impede action. To establish long-term trends ... -
Do cold, low salinity waters pass through the Indo-Sri Lanka Channel during winter?
(Taylor and Francis, 2011)During winter, along the east coast of India, the near-surface flow is characterized by the southward-flowing East India Coastal Current (EICC) which bends around Sri Lanka and enters into the south-eastern Arabian Sea ... -
A role for antioxidants in acclimation of marine derived pathogenic fungus (NIOCC 1) to salt stress
(Elsevier, 2012)Salinity tolerance a key factor helps in understanding the ionic homeostasis in general is a fundamental cellular phenomenon in all living cells. A marine derived pathogenic fungus was examined for its adaptation under ... -
Short-term observation of beach dynamics using cross-shore profiles and foreshore sediment
(Elsevier, 2012)Cross-shore beach profiles and textural characteristics of foreshore sediment were analyzed for understanding an annual cycle of intertidal beach dynamics at Devbag, an Island sheltered estuarine coast. Cross-shore transects ... -
Interannual and seasonal variations in nearshore wave characteristics off Honnavar, west coast of India
(Current Science Association, 2012)Interannual and seasonal variations in nearshore surface wave parameters over a period of three years (March 2008 - March 2011) were examined based on the measured wave data at 9 m water depth off Honnavar, west coast of ... -
Intra-annual variations of arsenic totals and species in tropical estuary surface sediments
(Elsevier, 2012)Arsenic totals and species were found to vary during a one year period in the surface sediments of Godavari estuary (the third largest river in India). This study suggests that increasing salinity of overlying water column ... -
Deep carbon export from a Southern Ocean iron-fertilized diatom bloom
