Cooperation in the Arctic region has been fruitful in the past few decades, generating several multilateral organizations and forums covering the entire circumpolar North. In many cases, forums were created to serve as catalysts, bringing together decision-makers from different backgrounds in a conference setting to promote dialogue and the exchange of ideas. To enquire about the possibility of creating a forum of cooperation in the eastern North American Arctic, a total of five governmental officials from Canada, Denmark, Nunavut, Québec and Greenland, and one elected representative from Greenland were interviewed with the same set of five questions. The governmental officials …

Moss tundra with a thick peat layer dominated by bryophytes is one of the most important ecosystems in the High Arctic of Svalbard, but little is known about the carbon dynamics of moss tundra. Here, we estimated the net primary production (NPP) and net ecosystem production (NEP) of moss tundra on Brøggerhalvøya (Brøgger Peninsula) of north-western Svalbard (79°N). The net photosynthetic and respiration rates of the two dominant moss species, Calliergon richardsonii and Tomenthypnum nitens, were measured under laboratory conditions. On the basis of the photosynthetic and respiration characteristics and climatic data, we estimated the cumulative NPP of the dominant …

The Pan-Eurasian Experiment (PEEX) is a new multidisciplinary, global change research initiative focusing on understanding biosphere-ocean- cryosphere-climate interactions and feedbacks in Arctic and boreal regions in the Northern Eurasian geographical domain. PEEX operates in an integrative way and it aims at solving the major scientific and society relevant guestions in many scales using tools from natural and social sciences and economics. The research agenda identifies the most urgent large scale research guestions and topics of the landatmosphere-aquatic-anthropogenic systems and interactions and feedbacks between the systems for the next decades. Furthermore PEEX actively develops and designs a coordinated and coherent ground …

New permafrost feature - deep crater in central Yamal (west Siberia, Russia) as a response to local climate fluctuations

This paper is based on field data obtained during short visits to a newly formed permafrost feature in a form of relatively narrow, deep crater. Excluding impossible and improbable versions of the crater's development, the authors conclude that it originated from warmer ground temperatures and an increase in unfrozen water content, leading to an increase in pressure from gas emissions from permafrost and ground ice. This conclusion is also supported by known processes in the palaeo-geography of Yamal lakes and recent studies of gas-hydrate behavior and subsea processes in gas-bearing provinces.

Успех преподавания каждой науки значительно обусловливается степенью развития метода, общепринятых и оказавшихся целесообразными практических приемов; чем более развиты метод и приемы преподавания любой науки, тем легче могут быть пополняемы пробелы в отношении к пособиям, учебникам по данному предмету; с другой стороны,—чем богаче и лучше устроен прибор преподавания (Lehrapparat) какой-либо науки, тем легче и тем успешнее профессора при университетском преподавании решают сложную и трудную - задачу сообщения своим слушателям главного содержания науки и существенных правил для занятий ею.
