Russian-American expedition will continue to study the Arctic climate – REGNUM

->

St. Petersburg, August 23, 2015, 17:39 – REGNUM For for example, members of the expedition expect to know in this connection Arctic Ocean, earlier round of drift ice in the last decade, more and more anomalous widely cleared of ice shell during the Arctic summer

On Saturday, August 22, from the northern port of Arkhangelsk published research vessel « Academic Treshnikov “on board in the long Arctic expedition went to more than forty Scientists from Russia, USA, Germany, Poland, South Korea, Britain and New Zealand. Back on dry land natural scientists plan to end of September . For information about the expedition plans to IA REGNUM reported in the press service of Arctic and Antarctic Research Institute .

This Arctic expedition takes place in the second phase of works on the program of long-term monitoring of the state of water basins Nansen and Amundsen, and (Nansen Amundsen Basins Observation System – NABOS). Russian Scientists called AVLAP program (Atlantic water in the Laptev Sea). The project AVLAP / NABOS were started More in 2002. Their first this nn Rodley until 2009. During this period, scientists was established 29 submerged buoy stations, of which raise the surface was only 17. The rest were lost or understand them was not possible .

Four years later, the project AVLAP / NABOS was revived for a period of from 2013 to 2018 . While being held in August and September 2015 Expedition Scientists are planning to raise the measuring buoy Station established in 2013 and set in the model sites more eleven stations, measuring devices that will record the temperature change, salinity sea water, the speed and direction of currents. Measuring stations plan to install along the border of the continental slope.

In addition to the parameters of the aquatic environment, Scientists are planning to record meteorological parameters drive layers of the atmosphere, which in the water and on the surface of the pack ice will be installed respective meteoizmeriteli.

Works are project of the Russian-American scientific cooperation in the field of hydro-meteorology, hydrology, oceanography, a memorandum which was signed between the Federal Service for Hydrometeorology and Environmental Monitoring (Roshydromet) and National Administration Oceanic and Atmospheric (NOAA) US Department of Commerce in 2005.

By tracking the seasonal and interannual variability of biochemical and hydrological parameters water regime , Scientists are planning to find out what role the proce tr ss ansformatsii Atlantic water has on the formation of the climate in the Arctic. Tracking chemical indicators of water and air environments, Scientists will add to the scientific knowledge of the global carbon cycle in the ocean and on its borders with the atmosphere and the lithosphere.

Recall biogeochemical carbon cycle – a process components the cycle of this element in Leto -, Hydro – and the atmosphere. For eg in the air Earth shell carbon is present in the form of oxide and dioxide: Carbon monoxide (CO) and carbon dioxide ( CO ₂ ), and methane. In large part this element is reserved in the form of complex organic compounds, including living organisms. Even slight changes in the carbon cycle on at our planet leads to strong changes in the earth image. studying a geological “chronicle» Scientists found that ice ages were characterized by a significant decrease in the concentration of CO ₂ and CH ₄ in the atmosphere.
