Aerosol Studies on and Around Antarctica
نویسندگان
چکیده
Antarctica provides an excellent environment to examine the natural and background aerosols in the atmosphere over snow and ice. The Indian efforts (metrological measurements) at Antarctica were initiated with the establishment of the first Antarctic station in Eastern Antarctica during the first Indian Scientific Expedition to Antarctica (ISEA) in 1981. The detailed and systematic characterization of physical and optical properties of coastal Antarctic aerosols over Indian Antarctic stations Maitri and Bharati were initiated during the International Polar Year (IPY) 2007 to 2009. Since then, several scientific publications were emerged from the Indian side on Antarctic aerosols. This article provides a brief review of the Indian efforts on Antarctic aerosols.

Antarctic new particle formation from continental biogenic precursors
Over Antarctica, aerosol particles originate almost entirely from marine areas, with minor contribution from long-range transported dust or anthropogenic material. The Antarctic continent itself, unlike all other continental areas, has been thought to be practically free of aerosol sources. Here we present evidence of local aerosol production associated with melt-water ponds in continental Anta...

The Larsemann Hills range is an ice-free oasis on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica, which includes Bharti Island, Fisher Island, McLeod Island, Broknes Peninsula, Stornes Peninsula, and several other islands, promontories, and nunataks. The Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills a...

A clear understanding of new particle formation processes in remote oceans is critical for properly assessing the role of oceanic dimethyl sulfide (DMS) emission on the Earth’s climate and associated climate feedback processes. Almost free from anthropogenic pollutants and leafed plants, the Antarctic continent and surrounding oceans are unique regions for studying the lifecycle of natural sulf...

متن کاملIntermediate Production of Mono- and Diolein by an Immobilized Lipase from Candida antarctica
Lipase from Candida antarctica, fixed on macroporous acrylic resin, has been used for the intermediate production of mono- and diolein by hydrolysis of triolein. The effect of altering concentrations of triolein and glycerol and the function of the molecular sieve on the hydrolysis reaction of triolein were investigated. The highest hydrolysis yield was observed for the utmost concentration of ...
