An integrated expedition of scientists from KarRC RAS to the White Sea Tersky Coast ended on July 15th. It was a continuation of the study of this arctic territory which started last year.
Being difficult to access, the northern part of the Tersky Coast is rather poorly studied. Research vessels in possession of KarRC RAS enable the Center’s scientists to reach such territories and survey them. The White Sea expedition was based on board the Ekolog research vessel.
The team split into several groups for most of the fieldwork. One of the focus areas was the study of permafrost-underlain palsa bogs. Their thawing is monitored as a marker of climate change. Palsa bogs were studied by Senior Researcher at the Department for Multidisciplinary Research (DMR) KarRC RAS Pavel Ryazantsev, Head of the Mire Ecosystems Laboratory of the Institute of Biology KarRC RAS Stanislav Kutenkov, Junior Researcher at the Laboratory for Ecological Monitoring and Modeling DMR KarRC RAS Yulia Tkachenko, and Doctoral Student at the Petrozavodsk State University Aleksey Kabonen.
Researchers from the Laboratory for Ecological Monitoring and Modeling DMR KarRC RAS Nikolai Petrov and Boris Raevsky continued working on the set of field keys, which are necessary for mapping modern vegetation using satellite images as the basis.
Species identification and monitoring were the tasks for botany expert, Senior Researcher at the DMR KarRC RAS Think Tank Aleksey Kravchenko and entomologist, Leading Researcher at the Laboratory for Landscape Ecology and Forest Ecosystem Protection of the Forest Research Institute KarRC RAS Andrey Humala. Senior Researcher at the Laboratory for Precambrian Geology and Geodynamics of the Institute of Geology KarRC RAS Pavel Medvedev studied rock species of the northern Kola Peninsula.
– All expedition participants have managed to accomplish the planned activities and tasks. The collected data will now be treated and analyzed. They will soon be presented in our reports and scientific papers, – remarked the expedition leader, DMR KarRC RAS Secretary for Science Nikolai Petrov.
The expedition was organized by the Department for Multidisciplinary Research (DMR) KarRC RAS. More details on the results and activities of its participants will be published in further posts on our website.

Karelian biologist Viktor Mironov carried out a novel study on the daily effects of solar activity on plant growth. Previously, this phenomenon was usually studied on a yearly scale. The new detailed approach and personally done measurements of increment in over 160 000 moss shoots have helped the scientist discover previously unknown effects of solar activity.

Specialists from the Forest Research Institute (FRI) KarRC RAS study how spruce advance regeneration adapts to an abrupt change in light conditions in gaps formed by thinning. To this end, researchers started a large-scope two-year experiment with 12 forest plots for monitoring trees in different settings. This integrated study will serve both for theoretical science – improving the understanding of tree adaptation mechanisms, and for applied tasks – its results will form the background for silvicultural operations meant to form high-productivity coniferous stands.
