Palaeoenvironmental studies were carried out on Kamchatka under the umbrella of the joint Russian-German BMBF Project KALMAR (Kurile-Kamchatka and Aleutian Marginal Sea-Island Arc Systems: Geodynamic and Climate Interaction in Space and Time" in subproject "Limnogeological Reconstruction of the late Quaternary Climate and Environment of Kamchatka". They were funded by the German Ministry of Research and Education (2006-2009). Since 2015, studies of palaeolimnological records from Kamchatka and the Kurile Islands are continued in a project entitled "Holocene Environment of far-east Siberia", which is funded by the German Research Foundation (DFG).

The study area is an important climate-sensitive region within the global climate system. The maritime-influenced region is situated at the border of the Eurasian landmass and the North Pacific, and as such offers the potential to pinpoint connections of environmental changes between landmass and ocean in the north‐west Pacific realm. It is situated at the eastern end-loop of the global thermohaline ocean conveyor belt and is strongly affected by atmospheric teleconnections (Pacific Decadal Oscillation, El-Niño/Southern-Oscillation, Arctic Oscillation), oceanographic, cryospheric, tectonic, and volcanic processes in the Arctic and subarctic Pacific regions and neighbouring landmasses of north-eastern Eurasia.
While there are many detailed Holocene palaeoenvironmental records across the northern hemisphere, quantitative climate reconstructions from eastern and far-eastern Siberia are still rare. This is a serious gap in our understanding of past climate change, so that the nature of climatic teleconnections between the North Atlantic and the North Pacific is problematic to understand. Extremely scarcely populated, Kamchatka and the Kurile Islands remain among the least studied regions on Earth. Many areas of wilderness, that have little impact by humans make Kamchatka and the Kurile Islands valuable places for the study of palaeoenvironmental changes under natural climate variability.
Building on the progresses in KALMAR, current work will provide both qualitative and quantitative palaeoenvironmental data for a better understanding of Holocene climate dynamics at the continental-maritime intersection in easternmost Siberia. A multiproxy palaeolimnological approach is applied, with emphasis numerical data of palaeotemperatures and palaeohydrology (sedimentology, chironomids, diatoms, biomarker).
