    Reply to Reviewer #1 Interactive comments on “PeRL: A Circum-Arctic Permafrost Region Pond and Lake Database” by Sina Muster et al. We sincerely thank the reviewer for his/her positive and constructive comments on our manuscript. Our responses to the reviewer’s comments are highlighted in bold. Changes done in the manuscript are marked in italic. Page and line numbers refer to the marked-up manuscript version which is attached to this review as well as the new supplement. Anonymous Referee #1 Received and published: 10 February 2017 This manuscript describes a database (PeRL) that maps ponds and lakes for the Circum-Arctic Permafrost region. The authors provide detailed information on the generation of the database, how images were processed and classified. Additionally, they discuss classification accuracy and uncertainty as well as the potential use of the database. This database is a very valuable contribution to the scientific community as well as potential stakeholders from outside science. As the authors describe, classifying the area of waterbodies in the Arctic is crucial, as it impacts permafrost degradation and carbon fluxes of permafrost lowlands. The introduction is very well written and delivers the right message on why this database is useful. The second chapter defines ponds and lakes, which I thought was really useful, since I usually don’t think about lakes and ponds, and chapter three explained the study areas. Up to this point I could easily follow the manuscript and I don’t have any major comments. Chapter four deals with the generation of the PeRL database and because image processing or classification are not my expertise I cannot comment much on the correctness of the methods.

  • Climate Change in the North
    Climate Change in the North 2018 Manitoba Envirothon Study Guide The Arctic is still a cold place, but it is warming faster than any other region on Earth. Over the past => years, the Arctic’s temperature has risen by more than twice the global average. Increasing concentrations of greenhouse gases in the atmosphere are the primary underlying cause: the heat trapped by greenhouse gases triggers a cascade of feedbacks that collectively amplify Arctic warming. 4 Snow, Water, Ice and Permafrost in the Arctic (SWIPA) 2017 and future consequences of Arctic climate change and its effects on Arctic snow, water, ice and permafrost conditions. Cryospheric change and variability are fundamentally linked to climate change and climate variability. Global climate models use mathematical formulations of atmospheric behavior to simulate climate. Tese models reproduce historical climate variations with considerable success, and so are used to simulate future climate under various scenarios of greenhouse gas emissions. Tese simulations of possible future conditions are driven by different atmospheric greenhouse gas concentration trajectories (known as Representative Concentration Pathways or RCPs), which provide a means to examine how future climate could be affected by differences in climate policy scenarios and greenhouse gas emissions. Tese scenarios of future atmospheric greenhouse gas concentrations used to drive global climate models have been employed to estimate future trajectories in Arctic temperature and their impacts on major components of the Arctic cryosphere (snow, permafrost, sea ice, land-based ice), establishing pan-Arctic projections. SWIPA 2017 has relied on the global scenarios and climate projections of the Fifth IPCC Assessment Report (IPCC, 2013, 2014a,b) as the ‘climate Figure 1.1 Te Arctic, as defined by AMAP and as used in this assessment.

  • MODERN PROCESSES and PLEISTOCENE LEGACIES by Louise M. Farquharson, Msc. a Dissertation Submitted In
    ARCTIC LANDSCAPE DYNAMICS: MODERN PROCESSES AND PLEISTOCENE LEGACIES By Louise M. Farquharson, MSc. A Dissertation Submitted in Partial Fulfillment of the Requirements For the Degree of Doctor of Philosophy in Geology University of Alaska Fairbanks December 2017 APPROVED: Daniel Mann, Committee Chair Vladimir Romanovsky, Committee Co-Chair Guido Grosse, Committee Member Benjamin M. Jones, Committee Member David Swanson, Committee Member Paul McCarthy, Chair Department of Geoscience Paul Layer, Dean College of Natural Science and Mathematics Michael Castellini, Dean of the Graduate School Abstract The Arctic Cryosphere (AC) is sensitive to rapid climate changes. The response of glaciers, sea ice, and permafrost-influenced landscapes to warming is complicated by polar amplification of global climate change which is caused by the presence of thresholds in the physics of energy exchange occurring around the freezing point of water. To better understand how the AC has and will respond to warming climate, we need to understand landscape processes that are operating and interacting across a wide range of spatial and temporal scales. This dissertation presents three studies from Arctic Alaska that use a combination of field surveys, sedimentology, geochronology and remote sensing to explore various AC responses to climate change in the distant and recent past. The following questions are addressed in this dissertation: 1) How does the AC respond to large scale fluctuations in climate on Pleistocene glacial-interglacial time scales? 2) How do legacy effects relating to Pleistocene landscape dynamics inform us about the vulnerability of modern land systems to current climate warming? and 3) How are coastal systems influenced by permafrost and buffered from wave energy by seasonal sea ice currently responding to ongoing climate change? Chapter 2 uses sedimentology and geochronology to document the extent and timing of ice-sheet glaciation in the Arctic Basin during the penultimate interglacial period.

  • 28 PHYSIOGRAPHY and RELATED SCIENCES Arctic Lowlands And
    28 PHYSIOGRAPHY AND RELATED SCIENCES Arctic Lowlands and Plateaux, geological conditions are favourable for commercial petro­ leum accumulation but serious exploration, guided by known regional geology has only recently begun in this vast area. Lead and zinc deposits in dolomitic, reefoid limestones might be expected on geological grounds. Regions in which reefoid dolomites lie near boundaries of calcareous rocks where they change to dark shales of the same age might be most favourable, according to some genetic hypotheses. Massive, pyritic base-metal sulphide deposits would probably be most likely to lie within volcanics in the northern, eugeosynclinal belt of the Franklinian geosyncline. Arctic Lowlands and Plateaux.—These geological and physiographic divisions lie in large basins separated by arches and belts of exposed Precambrian crystalline rocks. Gently inclined or flat sediments underlying the basins tend to be thin sandstones and limestones near the basal contact with metamorphosed Precambrian rocks but limestones and dolomites of Middle Ordovician to Early Devonian age are the principal rock types and at some localities are estimated to be up to 18,000 feet thick. Shales, sandstones and restricted areas of conglomerates of Middle Devonian to Late Devonian age are nor­ mally the youngest rocks preserved. Reefoid, vuggy dolomites of Middle Ordovician to Middle Silurian age commonly contain bituminous residues in surface exposures, structural and stratigraphic traps are probably present, and thick sections of potential source beds of petroleum and gas are known. Active oil seepages have not been reported. Petroleum exploration, aided by prior geological knowledge and published maps, began during the mid-1950s. Beds of gypsum admixed with some shale up to 970 feet thick are exposed in many localities in Middle Ordovician beds.

Two types of rock; and form most of the shield. These rocks contain minerals such as and in great quantities. Because of this, the Canadian Shield is often called the “storehouse of “. Minerals were deposited in the shield as slowly intruded and cooled. Many cities and towns, such as in Ontario or in the Northwest Territories, rely on the mining industry for jobs. The shield is ill suited for due to thin soils, but is ideal for . The plentiful water flow has made the region an excellent source of energy. Since the outer portion of the shield is lower than the centre (similar to a ), most of the rivers flow towards its centre and into The Lowlands Surrounding the Canadian Shield are the following three lowland regions: a) b) c) The sediments that form the bedrock under these regions were from the Shield.

  • Application of Landsat-7 Satellite Data and a DEM for the Quantification Of
    Application of Landsat-7 satellite data and a DEM for the quantifi cation of thermokarst-affected terrain types in the periglacial Lena–Anabar coastal lowland Guido Grosse, Lutz Schirrmeister & Timothy J. Malthus Extensive parts of Arctic permafrost-dominated lowlands were affected by large-scale permafrost degradation, mainly through Holocene thermokarst activity. The effect of thermokarst is nowadays observed in most periglacial lowlands of the Arctic. Since permafrost degradation is a consequence as well as a signifi cant factor of global climate change, it is necessary to develop effi cient methods for the quantifi cation of its past and current magnitude. We developed a procedure for the quantifi cation of periglacial lowland terrain types with a focus on degradation features and applied it to the Cape Mamontov Klyk area in the western Laptev Sea region. Our terrain classifi cation approach was based on a combina- tion of geospatial datasets, including a supervised maximum likelihood classifi cation applied to Landsat-7 ETM+ data and digital elevation data. Thirteen fi nal terrain surface classes were extracted and subsequently characterized in terms of relevance to thermokarst and degradation of ice-rich deposits. 78 % of the investigated area was estimated to be affected by permafrost degradation. The overall classifi cation accuracy was 79 %. Thermokarst did not develop evenly on the coastal plain, as indicated by the increasingly dense coverage of thermokarst-related areas from south to north. This regionally focused procedure can be extended to other areas to provide the highly detailed periglacial terrain mapping capabilities currently lacking in global-scale permafrost datasets. G.

This has profound effects on permafrost that underlies most of the arctic land area. Permafrost thawing can lead to the liberation of considerable amounts of greenhouse gases as well as to significant changes in the geomorphology, hydrology, and ecology of the corresponding landscapes, which may in turn act as a positive feedback to the climate system. Vast areas of the east Siberian lowlands, which are underlain by permafrost of the Yedoma-type Ice Complex, are particularly sensitive to climate warming because of the high ice content of these permafrost deposits. Thermokarst and thermal erosion are two major types of permafrost degradation in periglacial landscapes. The associated landforms are prominent indicators of climate- induced environmental variations on the regional scale. Thermokarst lakes and basins (alasses) as well as thermo-erosional valleys are widely distributed in the coastal lowlands adjacent to the Laptev Sea. This thesis investigates the spatial distribution and morphometric properties of these degradational features to reconstruct their evolutionary conditions during the Holocene and to deduce information on the potential impact of future permafrost degradation under the projected climate warming.
