The detection of annual hypoxia in a low latitude freshwater reservoir in Kerala, India, using the small AUV Maya
(Marine Technology Society, 2009)
The Idukki Reservoir at an altitude of 748 m covering an area of 53 km sup(2) is surrounded by tropical forests in the Western Ghats in the southwestern Indian state of Kerala. We used the small autonomous underwater vehicle ...
Observed thermohaline structure and cooling of Kochi backwaters and adjoining southeastern Arabian Sea
(Current Science Association, 2009)
Thermohaline structure of Kochi backwaters under fair and rough weather conditions has been examined along with thermal structure of two open-ocean islands in the adjoining southeastern Arabian Sea (Kavaratti and Andrott ...
The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa
(National Inquiry Services Centre, 2006)
Analysis of sea-level data obtained from the Atlantic Global Sea Level Observing System (GLOSS) sea-level station at Takoradi, Ghana, West Africa, clearly reveals a tsunami signal associated with the M sub(w) = 9.3 Sumatra ...
Mechanical design and development aspects of a small AUV - Maya
(Institute for Systems and Robotics, 2007)
This paper contains a description of the mechanical design route that was adopted in building a small AUV (Autonomous Underwater Vehicle). At the outset, it is decided to follow a set of guidelines that defined a broad set ...
Pressure gauge experiments in India
(UNESCO, 2004)
Pressure measurements made in differing turbid water bodies and turbulent clear-water bodies have led to the inference that the effective mean-depth in situ density value, Row eff, of these water bodies is less than the ...
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 ...
Biogeochemistry and trophic structure of a cold seep ecosystem, offshore Krishna-Godavari basin (east coast of India)
(Elsevier, 2022)
Active cold seep sites associated with shallow gas hydrates were recently reported from Krishna-Godavari (K-G) basin, off east coast of India. Benthic fauna including chemosymbiotic bivalves (genera Bathymodiolus, Acharax, ...
