(S.Z. Qasim Felicitation Committee, Goa, 1987) -
Control and interannual variability of dimethyl sulfide in the Indian Ocean
(American Geophysical Union, 2002)Aqueous dimethyl sulfide (DMS) concentrations and its sea-to-air fluxes were studied in upper layers (200 m) of the Indian Ocean, as a part of the Indian Ocean Experiment (INDOEX) that centered around the movement of the ... -
Control of source-to-sink processes on the dispersal, fractionation, and deposition of magnetic minerals in a tropical mesotidal estuarine system
(John Wiley & Sons, Ltd, 2023)This study aims to elucidate the control of source-to-sink processes on the sediment dynamics of a complex mesotidal tropical estuarine system using rock magnetic, sedimentological, mineralogical, and geochemical methods. ... -
Control of the Maya AUV in the vertical and horizontal planes: Theory and practical results
(Institute for Systems and Robotics, 2007)The paper describes the design and testing of the depth and heading autopilots for a small Autonomous Underwater Vehicle (AUV) named Maya. Control system design is done using the LQ (Linear-Quadratic) optimization technique ... -
Controlling 'new genes'- Letter

Controlling factors of the oxygen balance in the Arabian Sea's OMZ
(European Geosciences Union, 2012)The expansion of OMZs (oxygen minimum zones) due to climate change and their possible evolution and impacts on the ecosystems and the atmosphere are still debated, mostly because of the inability of global climate models ... -
Controls of contrasting provenance and fractionation on the sediment magnetic records from the Bay of Bengal
(Elsevier, 2021)We present the results of rock magnetic, granulometric, microscopy and mineralogical analyses of shelf sediments off Krishna, Godavari, and Mahanadi Rivers, Bay of Bengal. The aim of the study was to assess the influence ... -
Controls of dimethyl sulphide in the Bay of Bengal during BOBMEX-Pilot cruise 1998
(Indian Academy of Sciences, 2000)The air-sea exchange is one of the main mechanisms maintaining the abundances of trace gases in the atmosphere. Some of these, such as carbon dioxide and dimethyl sulphide (DMS), will have a bearing on the atmospheric heat ... -
Controls of mass transport deposit and magnetic mineral diagenesis on the sediment magnetic record from the Bay of Bengal
(Elsevier, 2021)We conducted rock magnetic, mineralogical, sedimentological and geochemical analyses on a sediment core (MD161/Stn-11) retrieved from a complex marine sedimentary system of Krishna-Godavari (K-G) basin to delineate the ... -
Controls on evolution of gas-hydrate system in the Krishna-Godavari basin, offshore India
(American Geophysical Union Publications, 2017)Abstract In this study, we integrate environmental magnetic, sedimentological, and geochemical records of sediment core of Hole NGHP-01-10D overlying methane hydrate deposits to decipher the controls on the evolution of ... -
Controls on ferromanganese crust composition and reconnaissance resource potential, Ninetyeast Ridge, Indian Ocean
(Elsevier, 2016)A reconnaissance survey of Fe–Mn crusts from the 5000 km long (~31°S to 10°N) Ninetyeast Ridge (NER) in the Indian Ocean shows their widespread occurrence along the ridge as well as with water depth on the ridge flanks. ... -
Controls on greigite preservation in a gas hydrate system of the Krishna-Godavari basin, Bay of Bengal
(Springer Verlag, 2020)Shallow sediments across large parts of Krishna-Godavari (K-G) basin offshore east central Indian contain abundant methane and gas hydrates. In this study, we carried out rock-magnetic and transmission electron microscope ... -
Controls on organic carbon distribution in sediments from the eastern Arabian Sea margin
(Springer, 1997)Sediment cores from the upper continental slope of the eastern Arabian Sea have high organic carbon (OC), CaCO sub(3), and sand content at the top. The values decrease with increasing depth in the Holocene and Upper ... -
Controls on organic matter distribution in oxygen minimum zone sediments from the continental slope off western India
(Elsevier B.V., 2020)The causes of organic-rich sediments in contact with the perennial oxygen minimum zone (OMZ) on the continental slope off western India have been debated extensively, largely in relation to two main controlling factors: ... -
Controls on the distribution and fractionation of yttrium and rare earth elements in core sediments from the Mandovi estuary, western India
(Elsevier, 2015)Mineralogy, major elements (Fe, Mn and Al), rare earths and yttrium (REY) of bulk sediments were analyzed in four gravity cores recovered along the main channel of the Mandovi estuary, western India, to determine the sources ... -
