A new record of Morula anaxares with a description of the radula of three other species from Goa, Central West Coast of India (Gastropoda: Muricidae)
(Central Fisheries Research Institute (CFRI) Trabzon, 2012)The present paper describes a new record of Morula anaxares (Kiener 1835) (Muricidae) from Goa, Central West coast of India aided by spiral cord ontogeny, aperture morphology of shell and SEM of radula. This species was ... -
Brittle stars (Echinodermata: Ophiuroidea) from seamounts in the Andaman Sea (Indian Ocean): first account, with descriptions of new species
(Marine Biological Association of the United Kingdom, 2012)Brittle stars were collected on two seamounts in the Andaman Back-arc Basin. Of the six species, two were new to science and are described herein as Ophioleuce longispinum sp. nov. and Ophiophyllum minimum sp. nov., in the ... -
Corrosion of mild steel and stainless steel by marine Vibrio sp.
(Indian Association for Limnology and Oceanography, 1989)Microbially induced corrosion (MIC) of stainless steel and mild steel coupons exposed to media with and without a bacterial culture Vibrio sp. was studied using Scanning Electron Microscope (SEM). Pitting type of corrosion ... -
Diagenesis of magnetic minerals in a gas hydrate/cold seep environment off the Krishna-Godavari basin, Bay of Bengal
(Elsevier, 2013)Detailed magnetic measurements of the core (MD161/8) located in the vicinity of Site NGHP-01-10 was carried out, where approx. 128 m of hydrate is confirmed by drilling/coring, to understand the diagenesis of magnetic ... -
Extracellular polysaccharide production by Thraustochytrid protists
(Springer, 2005)Four strains of marine stramenopilan protists, the thraustochytrids, were studied for their ability to produce extracellular polysaccharides (EPSs). Observations by light and scanning electron microscopy revealed the ... -
First description of a cyanophage infecting the cyanobacterium Arthrospira platensis (Spirulina)
(Springer, 2013)Cyanobacteria constitute a versatile group of photosynthetic bacteria of immense commercial and ecological importance. Some species of this group are cultivated and sold as food because of their high nutritional value. ... -
Gyrineum natator: A potential indicator of imposex along the Indian coast
(Elsevier, 2006)Imposex related studies have used neogastropods as sentinel organism. In this effort, we elucidate the potential of a mesogastropod, Gyrineum natator, for imposex monitoring on the central west coast of India. Observations ... -
Impact microcrater morphology on Australian microtektites
(Meteoritical Society, 2003)Scanning electron microscopy of 137 Australian microtekties and fragments from 4 sediments cores in the Central Indian Ocean reveals more than 2000 impact-generated features in the size range of 0.3 to 600 mu m. Three ... -
Monsoon signatures in recent corals from the Laccadive Islands
(Indian Association of Sedimentologists, Aligarh, 1997)X-radiographs of the coral (Porites sp.) collected from several atolls of Lakshadweep show alternate bands of low and high density, formed in non-monsoon period and monsoon period, respectively. The results reveal annual ... -
Spatial and temporal distribution of foraminifera in sediments off the central west coast of India and use of their test morphologies for the reconstruction of paleomonsoonal precipitation
(Micropaleontology Press, 1999)From the shallow region off the central west coast of India, 21 samples of surface sediments (ranging in depth from 22 to 52 m) along with two sediment cores of 4.80 m and 4.00 m (surface/subsurface) have been analyzed for ... -
Surface textures of quartz grains from Goa coast - An application of the scanning electron microscope
(Allied, India, 2005)The scanning electron microscopy of quartz grains along the Goa beaches reveals 10 microfeatures. Three types of process response environments viz. Beach (Littoral), subaqueous and low to high-energy chemical environments ... -
Thraustochytrid protists as a component of marine microbial films
(Springer, 2000)Although ubiquitous in the marine environment, the presence and importance of thraustochytrid fungoid protists in primary film formation of freshly immersed surfaces in the sea have not been investigated. Thraustochytrids ...
