Was the Rann of Kachchh navigable during the Harappan times (Mid-Holocene)? An archaeological perspective
(Current Science Association, 2013)The Kachchh region, presently, is one of the difficul t areas in the Indian subcontinent for human settlement due to harsh climate, scanty rainfall and hence no scope for agriculture production. However, the region was ... -
Micrometeorite flux on Earth during the last ~50,000 years
(American Geophysical Union, 2013)Flux of micrometeorites is estimated by using cosmic spherule counts from a seafloor area of 2.50 ms<sup>2</sup> from the Indian Ocean. The spherules are recovered from sediment samples in close-spaced locations from the ... -
Origins of wind-driven intraseasonal sea level variations in the North Indian Ocean coastal waveguide
(American Geophysical Union, 2013)In this paper, it is shown that a linear, continuously stratified ocean model reproduces observed wind-driven intraseasonal sea level variability in the coastal waveguide of the Northern Indian Ocean (NIO). Sensitivity ... -
Small protohistoric sites (fishing villages?) on the saurashtra coast, West Coast of India
(Annon, 2013)During the maritime archaeological explorations a few sites of protohistoric in nature have been noticed along the saurashtra coast. the trial excavations of a few sites namely Bet Dwarka and Bhokhira on the western ... -
ENSO-Modulated Cyclogenesis over the Bay of Bengal
(American Meteorological Society, 2013)The role of the El Niño–Southern Oscillation (ENSO) on the modulation of tropical cyclone activity over the Bay of Bengal (BoB) for the 1979–2011 period is examined. It is shown that Niño-3.4 sea surface temperature (SST) ... -
Role of mesoscale eddies on the variability of biogenic flux in the northern and central Bay of Bengal
(American Geophysical Union, 2013)Mesoscale cyclonic eddies (cold core) are though known to enhance the phytoplankton biomass in the Bay of Bengal, their contribution to the carbon export to the deep ocean are yet to be quantified. Using biogenic flux data ... -
‘Thermohaline front’ off the east coast of India and its generating mechanism
(Springer, 2013)Physical oceanography measurements reveal a strong salinity (0.18 psu km−1) and temperature (0.07 °C km−1) front off the east coast of India in December 1997. T–S diagrams suggest lateral mixing between the fresh water at ... -
Harnessing the biosphere to mitigate global climate change and sea level rise
(Lights Research Foundation, 2013)The planetary ice cover, from Himalayan glaciers to Arctic sea ice, is shrinking at much higher rates than anticipated by climate models, presumably due to feedback processes amplifying the rate of global warming and ... -
Influence of physical and biological processes on the seasonal cycle of biogenic flux in the equatorial Indian Ocean
(European Geosciences Union, 2013)Seasonal cycle of biogenic fluxes obtained from sediment trap at two locations 5°24` N, 86°46` E (southern Bay of Bengal trap; SBBT) and 3°34` N, 77°46` E (equatorial Indian Ocean trap; EIOT) within the equatorial Indian ... -
Caldimonas meghalayensis sp. nov., a novel thermophilic betaproteobacterium isolated from a hot spring of Meghalaya in northeast India
(Springer, 2013)While studying the microbial diversity of hot springs of North-east India we isolated a strain AK31<sup>T</sup> from the Jakrem hot spring of Meghalaya. The strain formed light yellow colonies on nutrient agar and was Gram ... -
Recent advances in marine drug research
(Elsevier, 2013)Structures and properties of promising marine anti-cancer, anti-inflammation and anti-infectious (HIV, HSV, malaria, leishmania) compounds reported during 2008–2011 are discussed. Wherever possible, attempts have also been ... -
Spatial variations in isostatic compensation mechanisms of the Ninetyeast Ridge and their tectonic significance
(American Geophysical Union, 2013)The Ninetyeast Ridge (NER), one of the longest linear volcanic features on the Earth, offers an excellent opportunity of understanding the isostatic response to the interactions of mantle plume with the migrating mid-ocean ... -
Sub-tidal water-level oscillations in the Mandovi estuary, west coast of India
(Elsevier, 2013)Using water-level data collected at six locations during March–April 2003 in the main channel of the Mandovi estuary, one of the 50 odd estuaries on the west coast of India, we describe the nature of variability of water ... -
Cletocamptus goenchim sp. nov., a new harpacticoid (Copepoda: Harpacticoida) from India
(Biological Society of Washington, 2013)A new species of harpacticoid copepod, Cletocamptus goenchim sp. nov., was found in the mouth of the Mandovi estuary, Goa, India. This species seems to be the same reported in 1979 from Lake Kolleru (east coast of India) ... -
UV-absorbing bacteria in coral mucus and their response to simulated temperature elevations
(Springer, 2013)Reef-building corals encompass various strategies to defend against harmful ultraviolet (UV) radiation. Coral mucus contains UV-absorbing compounds and has rich prokaryotic diversity associated with it. In this study, we ... -
Factors controlling the temporal and spatial variations in Synechococcus abundance in a monsoonal estuary
(Elsevier, 2013)Temporal and spatial variations in Synechococcus abundance were investigated over an annual cycle (February`10–January`11) along a salinity gradient (0–35) in the tropical Zuari estuary, influenced by south-west monsoons. ... -
Copper addition helps alleviate iron stress in a coastal diatom: Response of Chaetoceros gracilis from the Bay of Bengal to experimental Cu and Fe addition
(Elsevier, 2013)Copper (Cu) is a transition metal with multi-oxidation states, and though it plays numerous roles in vital physiological and biochemical pathways including both photosynthesis and respiration, it can potentially be toxic ... -
Spatio-temporal distributions of delta<sup>18</sup>O, delta D and salinity in the Arabian Sea: Identifying processes and controls
(Elsevier, 2013)Isotopic compositions ( delta<sup>18O</sup> and deltaD) and salinity (S) of 683 surface water samples from the Arabian Sea (AS) collected during 2008–2010, were measured to understand the factors controlling the spatio-temporal ... -
Sea–air CO2 fluxes in the Indian Ocean between 1990 and 2009
(European Geosciences Union, 2013)The Indian Ocean (44° S–30° N) plays an important role in the global carbon cycle, yet it remains one of the most poorly sampled ocean regions. Several approaches have been used to estimate net sea–air CO<sub>2</sub> fluxes ... -
In vitro and in vivo activities of antibiotic PM181104
(American Society for Microbiology, 2013)Drug resistance has become a global threat that, if not addressed, may return us to the preantibiotic era. A way to overcome the problem of growing incidence of global antibiotic resistance is to introduce compounds belonging ...
