Overview of Activities

TRISH activities are evolved around three themes and address to understanding the Arctic Amplification and society-relevant scientific questions about hydroclimate change at the high latitude. Project activities are centered around

  1. Tree-ring proxy network,
  2. Hydrological modeling,
  3. TRISH Tool devilment and
  4. Training and Outreach, and
  5. International Collaboration Services.

New tree-ring network in Khakassia and Tuva

As now, the project developed a network of precipitation sensitive tree rings along the upper reaches of Yenisei River. The new tree-rig data dated to 2019 update and extend the historical network of tree-ring width chronologies in his region. Additionally, we developed a set of pseudo tree-ring records via VS-forward simulation. This new tree-ring dataset will be incorporated into TRISH- tool database.


Scythian archaeological site Large stone of the Great Salbyk kurgan. The area of tree-ring sampling has richest archaeological heritage in Siberia. Many kurgan fields burials have well-preserved timbers inside burials suitable for tree-ring analysis.

Mayna site Sampling on extremely steep slopes ensures the hydrological signal In tree-ring width variance. Growth conditions is very dry on these slopes. However, frequent fires

Conquest of the Yenisey monument

Mayna power station Sayano-Shushenskaya Dam, 242 m high, on the Yenisei River in Khakassia, Russia. This the largest power plant in Russia holds the 9th place among largest hydroelectric plant in the world. The dam impacts the natural river flow since 1963. Simulation of

Tuva field photo Larch and pine trees sampled in the vicinity of the Sayano-Shushenskaya Dam in Fall 2019. We search for old-growth trees on steep slopes in forest-steppe ecotones. Growth of oldest trees reaches the age of up to 400–430 years, but these trees are rare and hard to find.
