Karelian scientists setting off on an integrated expedition to the Tersky Coast of the White Sea on board of the Ekolog research vessel. They will spend a fortnight in the Kola Peninsula studying palsa bogs resting on permafrost, rare and invasive plant species, rock species and collecting material for vegetation mapping.
Arctic research is one of the priorities for the Karelian Research Centre RAS. On July 2nd, an expedition organized by the Department for Multidisciplinary Research (DMR KarRC RAS) started. Its participants are specialists in ecology, sylvics, geology, mire science, soil science, and botany. The southern part of the Tersky Coast was surveyed in summer 2021. This field season the same team will advance further north up the Kola Peninsula – along from the Ponoy River mouth to the Kachkovka River mouth.

– There is a large massif of permafrost-based palsa bogs in this area. Last year we managed to survey a palsa bog near Chavanga River, which is considered the southern limit of permafrost in the Kola Peninsula. To track how glaciers had developed and thawed we need to move farther north and survey the most extensive palsa bog massif, – tells Nikolai Petrov, expedition leader, Researcher, DMR KarRC RAS Secretary for Science.

Monitoring of thawing processes and state of palsa bogs in the Kola Peninsula can provide an important marker of global climate processes. Scientists are carrying along a set of modern equipment for the research.

This expedition will continue mapping modern vegetation on the basis of satellite images. To obtain input data, scientists need field keys – areas of known size and configuration with a detailed description of the forest vegetation. As northern territories are of little value for the forest industry, no recent updates of departmental information are available. Researchers will have to collect the field data needed for subsequent interpretation of satellite images. Such studies are necessary for monitoring the current state of vegetation and for preventing environmental risks.

Other expedition activities will be inventory of the local flora, study of bedrock species and rock outcrops. Quadcopter will be used to create air survey plans and 3D models.

The integrated expedition to the Tersky Coast will last until July 16th. It will be followed by treatment and analysis of the results.

Breams infected with ligula worms are edible

Biochemists and parasitologists at KarRC RAS studied how the wellbeing and nutritive value of the bream is affected by ligula – a flatworm that can grow to be several times as long as the host fish. To this end, scientists checked a number of crucial parameters in healthy and ligula-infected fish from Lake Syamozero. Analyses show that this parasite, non-hazardous for humans, does not have much effect on the quality of the fish either.
