Field evaluation of navigational sensors using DGPS/GPS for a small AUV
(Allied, India, 2003)
This paper presents the preliminary results of a field experiment for low-cost strap down IMU/GPS combination for the estimation of 2-D components of vehicle position (Trajectory). In present approach the effects of earth ...
Performance of Honeywell silicon pressure transducers
(Allied, India, 2003)
Simultaneous calibration of three Honeywell pressure transducers (PPTR) at four ambient temperatures have been carried out using a novel static calibration system developed in-house. Calibration results indicated that ...
Endurance and stability of some surface meteorological sensors under land- and ship-based operating environments
(Allied, India, 2005)
The endurance and stability of some surface meteorological sensors under land- and ship-based operating environments is described. The sensors evaluated are those for measurement of relative humidity, barometric pressure ...
TNF-a and IL-6 inhibitory effects of cyclic dipeptides isolated from marine bacteria Streptomyces sp.
(Springer and Business Media, 2017)
Inflammation is mediated by a variety of soluble factors, including a group of secreted polypeptides known as cytokines. The anti-inflammatory cytokines are a series of immune regulatory molecules that control the pro ...
Water column characteristics following the September 2004 stench event off southern Malabar coast
(NISCAIR, CSIR, 2007)
An unusual stench emanated from the coastal waters of southwest coast of India during September 2004 associated with an algal bloom. Water samples collected from 14 stations from the affected area after three weeks of the ...
Methane stimulates massive nitrogen loss from freshwater reservoirs in India
(Nature Publishing Group, 2018)
The fate of the enormous amount of reactive nitrogen released to the environment by human activities in India is unknown. Here we show occurrence of seasonal stratification and generally low concentrations of dissolved ...
Seasonal anoxia over the western Indian continental shelf
(American Geophysical Union, 2009)
The eastern Arabian Sea contains the only eastern-boundary-type upwelling environment in the entire Indian Ocean, albeit on a seasonal basis. During the southwest monsoon, when the surface current flows equatorward, upwelling ...
The relationship between volatile halocarbons and phytoplankton pigments during a Trichodesmium bloom in the coastal eastern Arabian Sea
(Elsevier, 2011)
Eukaryotic phytoplankton such as diatoms and prymnesiophytes produce biogenic halocarbons in the ocean that serve as important sources of chlorine and bromine to the atmosphere, but the role of cyanobacteria in halocarbon ...
Dissolved methane in Indian freshwater reservoirs
(Springer, 2013)
Emission of methane (CH4), a potent greenhouse gas, from tropical reservoirs is of interest because such reservoirs experience conducive conditions for CH4 production through anaerobic microbial activities. It has been ...
Benthic mineralization and nutrient exchange over the inner continental shelf of western India.
(European Geosciences Union, 2014)
The western Indian continental shelf is one of the most productive coastal systems of the world ocean. This system experiences extreme changes in its oxygen regime, being normoxic from November to May and suboxic ...
