Ambarchik (Russia)

Athmospheric research station at the Arctic Ocean

Continuous gas concentration measurements of carbon dioxide and methane in the permafrost region of the Siberian Tundra on the Arctic Ocean.

Description & History

In the past, the rural site, in Siberia on the coast of the Arctic Ocean, served as a transit prison camp in the Russian Gulag system. The Ambarchik locality also played a supporting role in Russian exploration of the Arctic.

Since 1935 until today the site has served as a polar research and meteorological station. The weather station is staffed by 2 people who read meteorological data every 3 hours and pass it on to the weather service.

In summer 2014, a tower for continuous gas concentration measurements of carbon dioxide and methane was built in close cooperation with Sergei A. Zimov.
 The station is equipped with a 27 m high tower and a Picarro analyzer for high precision measurements of CO2, CH4 and H2O, along with meteorological instrumentation.

The Ambarchik Station helps to shed light on permafrost-related processes in the global carbon budget. Its coastal location makes it possible to capture atmospheric signatures of carbon exchange processes from the Arctic Ocean and Siberian Tundra.

The project was part of Friedemann Reum's dissertation from the IPAS group (Integrating surface-atmosphere Exchange Processes Across Scales - Modeling and Monitoring), which is led by Matthias Goeckede.
