title: Uncrewed aerial vehicle remote sensing imagery of postfire vegetation in Siberian larch forests 2018-2019

description: This data set contains remote sensing imagery collected using uncrewed aerial vehicles at a series of fire perimeters in larch forests located in northeastern Siberia in 2018 and 2019. Images were collected using visible sensors (blue, green, and red wavelengths) and multispectral sensors (green, red, red-edge, and near-infrared wavelengths). The data were collected perpendicular to fire perimeter boundaries in order to characterize variation vegetation composition and structure between burned and burned forests, and as a function of distance from the unburned forest edge. The resulting images are co-located with field observations of ecosystem properties collected as part of this project that are posted in a related data set (Alexander et al, 2018).

title: Collection of data on judgments of the Special Court in Lublin (1939-1944)

description: The dataset contains the results of a survey of extant sentences handed down by the Special Court in Lublin. The data collected concerned both the persons accused (e.g. profession, gender, age, nationality), the act committed (e.g. charge, legal qualification, act attributed) and the sentence itself (e.g. composition of the court, type and length of sentence). These data were used in the article: Graczyk, K. (2024). Out of the Activities of the Special Court in Lublin (1939-1944). Studia Iuridica Lublinensia, t. 33, 2, 2024, s. 57–89, https://doi.org/10.17951/sil.2024.33.2.57-86

title: Spatial extent of Greenland firn aquifer detected by airborne radars, 2010-2017

description: Mass loss of the Greenland ice sheet has been accelerating since the 1990s, and in recent years (2009‐2012), about 85% of its rate of increase were due to increased surface melt and subsequent runoff. The Greenland surface melt extent and duration have increased over the last decade, in response to increased advection of warm air from the south during summers. Surface melt is not only occurring in the lower elevation margins of the ice sheet but also migrating toward the ice sheet interior, causing a reduction of the dry-snow zone and an expansion of the percolation zone. Widespread firn aquifers have been detected in high-accumulation regions of the ice-sheet percolation zone. In these regions, firn aquifers retain water for at least several years, storing a substantial amount of water responsible of heating the firn and delaying meltwater runoff. Their impacts on the ice sheet are numerous, including firn densification, alteration of the ice thermal state, and water input from the aquifer into the englacial hydrology system, which has the potential to affect ice dynamics and Greenland's contribution to sea level rise.
 This dataset provides the locations of firn aquifers for the high snow-accumulation regions of the Greenland ice sheet. To achieve this goal, we use National Aeronautics and Space Administration (NASA) Operation IceBridge Accumulation Radar data from six campaigns (2010-2014 and 2017) and the Multichannel Coherent Radar Depth Sounder (MCoRDS) from two campaigns (2015-2016). We pick the brighter reflection horizons in the firn which are due to strong dielectric contrasts created by the presence of water. For estimating a total firn-aquifer extent, we delineate polygons around flightlines showing water-saturated firn for the 2010-2017 period combined. With this method, we find a 28,750 km2 total extent. In addition of providing the firn aquifer extents map by the mean of polygons, we also provide yearly files with firn-aquifer coordinates and depth to the water table. This way, the interannual variability can be investigated in places with repeat flightlines for the 2010-2017 time period.

title: Surface Nuclear Magnetic Resonance (NMR) Soundings on Drained Lake Basins, North Slope, Alaska, 2015-2016

description: This dataset contains surface nuclear magnetic resonance (NMR) geophysical soundings acquired on five drained lake basins and two control sites on terrestrial upland permafrost (primary surface sites) during spring fieldwork 2015 - 2016. Measurements were made using a Vista Clara GMR (Mukilteo, Washington, Unites States of America) with a circle coincident transmitter/receiver loop either 75 meters (m) or 90 m diameter. Raw data for nine soundings are provided in the proprietary format created by the instrument, and results after processing and inversion with the GMR software (Mukilteo, Washington, Unites States of America; Walsh, 2008) are included as tabular values. The purpose of this research is to identify unfrozen bodies or taliks below drained lake basins to better understand the process of permafrost aggradation after lake drainage. Surface NMR is the only non-invasive geophysical method that is able to directly detect unfrozen water as it measures the response of hydrogen protons on liquid water (Walsh, 2008).

title: Snow, Thaw, Temperature, and Permafrost Borehole Data from Lake Colleen and Airport Study Sites, Prudhoe Bay, Alaska, 2016

description: This data report contains methods and data from transects, permanent vegetation plots, and boreholes sampled in March and August-September 2016 at Colleen Site A and the Airport Study Site, Prudhoe Bay, Alaska, for the Arctic Science, Engineering, and Education for Sustainability (ArcSEES) program. The ArcSEES project, "Cumulative effects of Arctic oil development—planning and designing for sustainability," was funded by the National Science Foundation (NSF Grant Nr. 1263854). The study sites consists of three 100-meter (m) transects established near the Deadhorse Airport and two 200-m transects near Lake Colleen. This builds on data collected in 2014 and 2015. In 2016, snow depth, thaw depth, temperature and permafrost borehole data were collected along transect flag lines and at permanent vegetation plots established at polygon centers and troughs at intervals along transects. The data report also includes 41 photos of the disturbance to the tundra caused by installation of the Quintillion terrestrial fiber optic cable along the Dalton Highway in 2015-2016.

title: Landscape and Permafrost Changes in the Prudhoe Bay Oilfield, Alaska (1949-2011)

description: Many areas of the Arctic are simultaneously affected by rapid climate change and rapid industrial development.These areas are likely to increase in number and size as sea ice melts and abundant Arctic natural resources become more accessible. Documenting the changes that have already occurred is essential to inform management approaches to minimize the impacts of future activities. Here, we determine the cumulative geoecological effects of 62 years (1949-2011) of infrastructure- and climate-related changes in the Prudhoe Bay Oilfield, the oldest and most extensive industrial complex in the Arctic, and an area with extensive ice-rich permafrost that is extraordinarily sensitive to climate change. We demonstrate that thermokarst has recently affected broad areas of the entire region, and that a sudden increase in the area affected began shortly after 1990 corresponding to a rapid rise in regional summer air temperatures and related permafrost temperatures. We also present a conceptual model that describes how infrastructure-related factors, including road dust and roadside flooding are contributing to more extensive thermokarst in areas adjacent to roads and gravel pads. We mapped the historical infrastructure changes for the Alaska North Slope oilfields for 10 dates from the initial oil discovery in 1968-2011. By 2010, over 34% of the intensively mapped area was affected by oil development. In addition, between 1990 and 2001, coincident with strong atmospheric warming during the 1990s, 19% of the remaining natural landscapes (excluding areas covered by infrastructure, lakes and river floodplains) exhibited expansion of thermokarst features resulting in more abundant small ponds, greater microrelief, more active lakeshore erosion and increased landscape and habitat heterogeneity. This transition to a new geoecological regime will have impacts to wildlife habitat, local residents and industry.

title: Seasonal water table depth (WTD) measurements from a Mobile Instrumented System Platform (MISP) grid, Barrow, Alaska, 2017

description: Water table depth (WTD) measurements were taken along the Mobile Instrumented System Platform (MISP) grid in Barrow, Alaska during the summer of 2017. The MISP grid is situated about 200 meters to the north east side of the International Tundra Experiment (ITEX) dry sites. If a uniform representation of the water table within each plot was visible, then a WTD tube was placed there to measure the change in water table throughout the season. For instance if the plot was half saturated and half dry, then that plot was skipped and no tube was placed there. The exact location of WTD tubes are as follows: Between meters 0-1, 2-3, 5-6, 7-8, 9-10, 11-12, 13-14, 15-16, 18-19, 20-21, 24-25, 26-27, 28-29, 30-31, 32-33, 34-35, 36-37, 38-39, 42-43, 44-45, 47-48, and 49-50. A total of 22 WTD tubes were installed into the MISP grid in Barrow. Measurements were made once a week during the summer snow free period between mid June and mid August. WTD was calculated as the difference between the depth (centimeter) of the water table above or below the measuring tube (- Values = water above tube, + Values= water level below the height of the tube) and the height of the top of the measuring tube above the ground level. Measurements were not made (NA in data sheet) if there was persistent snow cover, interference or disturbance from other experimental infrastructure, or if water table depth tubes were dry to the upper surface of the permafrost.
