the Northeast Science Station
The Northeast Science Station was
organized in 1989 by a group of young scientists from the Pacific Institute
of Geography of the Far East Branch of the Russian Academy of Sciences.
It currently operates within the Nizhnekolymskii Ulus of the Republic of Sakha, Yakutia.
Major funding for the station has been provided by
the Soros Foundation, the Russian Science Foundation, the Department of
Energy and the National Science Foundation of the United States of America.
- Scientific equipment
- The station has two laboratories and a network
of field sites.
- The major items of scientific equipment include
- Gas analysis: 2 gas chromatographs, 2
portable infrared gas analyzers [LiCor 6200], 4 high-resolution
infrared gas analyzers [LiCor 6262], equipment for collecting gas
samples for isotopic analysis, Dissolved oxygen analyzer [Hydrolab]
- Chemical analysis: CHN analyzer, spectrophotometer,
ph meters, electronic balances, glass-fiber filtration systems,
distilled/dionized water supply, muffle furnace
- Ecological field sampling: LiCor leaf
area meter; soil corers; portable field balances; drills for
ice, permafrost, and lake sediments; stream discharge meters;
sample drying ovens
- Meteorological data: air temperature,
precipitation, wind speed
- Eddy covariance measurements (3 sites):
Gill sonic anemometers, Licor 6262 infrared gas analyzers
(CO2, H20), Campbell data loggers (temperature, soil
moisture, relative humidity, wind speed direction, atmospheric
pressure), radiation sensor (net radiation, incoming and outgoing
shortwave, incoming and outgoing longwave, photosynthetically
- Data analysis and communication: PC and MacIntosh
computers, scanner, internet access
- Cutter for transportation on rivers and the Arctic
- Outboard motor boats
- Airplane (skis and floats)
- Snow machines
- Cars and vans (for transport along road system
- All-terrain vehicles
- Fully equipped houses with sleeping accomodations
for 12-14 persons
- Two dormitories with sleeping accomodations
for 5-6 persons each
- Town of Cherskii located 3 km from station
- Meals provided by arrangement
- Sergei A. Zimov, Director
- Sergei Davydov, Assistant Director
- Galina Zimova, Administrative Assitant
- Anna Davydova, Laboratory Technician
Please contact the station for advice as to the best
means of reaching the station.
- Many international scientists have travelled to
the station to study the Pleistocene deposits at Duvanyi Yar, and use the
station as a basis of operations for geological and marine investigations
along the coast of the Arctic Ocean.
- Research at Pleistocene Park is investigating the
causes of Pleistocene extinctions.
- The Northeast Science Station is studying global
carbon and methane fluxes.
- In 2001-2003, a tri-partite study
supported by the RAISE Project (Russian-American Initiativeof Shelf
Environments) of the Office of Polar Programs of the National Science
Foundation focused on impacts of disturbance on the seasonal cycle
of atmospheric CO2 and the discharge of carbon and nitrogen into the
" Recent increases in the seasonal amplitude of atmospheric
CO2 at high latitudes suggest a widespread biospheric response to high-latitude
warming. We have shown that the seasonal amplitude of net ecosystem
carbon exchange by northern Siberian ecosystems is greater in disturbed
than undisturbed sites, due to increased summer influx and increased winter
efflux. Net carbon gain in summer and respiration in winter were
greater in a cool than in a warm year, especially in disturbed sites and
did not differ between high-arctic and treeline sites, suggesting that
high-latitude warming, if it occurred, would have little effect or would
reduce seasonal amplitude of carbon exchange. We suggest that increased
disturbance contributes significantly to the amplified seasonal cycle of
atmospheric CO2 at high latitudes. "
