Mining typically involves extensive areas where environmental monitoring is spatially sporadic. New remote sensing techniques and platforms such as Structure from Motion (SfM) unmanned aerial vehicles (UAVs) may offer one solution for more comprehensive continuous measurements. We conducted UAV campaigns in three consecutive summers (2015–2017) at a sub-Arctic mining site production was temporarily suspended. The aim to monitor 0.5 km2 tailings impoundment measure potential subsidence of...
Abstract Subarctic ecohydrological processes are changing rapidly, but detailed and integrated investigations not as widespread necessary. We introduce an research catchment site (Pallas) for atmosphere, ecosystems, ecohydrology studies in subarctic conditions Finland that can be used a new set of comparative investigations. The Pallas provides unique observational data high‐intensity field measurement datasets over long periods. infrastructure atmosphere‐ to landscape‐scale ecosystem...
Abstract A combination of thermal infrared (TIR) images captured by uncrewed aircraft systems (UASs) and manual geophysical measurements with a GEM-2 device were used to better plan water sampling campaign at an abandoned Au-Cu mine active Ni-Cu-PGE in the sub-arctic boreal zone northern Finland. Anomalies from TIR conductivity values focus sampling. The hydrogeochemistry isotopic compositions oxygen (δ 18 O), hydrogen 2 H), strontium ( 87 Sr/ 86 Sr), sulfur 34 S) analyzed understand flow...
Abstract. Detailed information on seasonal snow cover and depth is essential to the understanding of processes, operational forecasting, as input for hydrological models. Recent advances in uncrewed or unmanned aircraft systems (UASs) structure from motion (SfM) techniques have enabled low-cost monitoring spatial distribution resolutions up a few centimeters. Here, we study spatiotemporal variability interactions between vegetation different subarctic landscapes consisting mosaic conifer...

Abstract. Snow conditions in the Northern Hemisphere are rapidly changing, and information on snow depth is critical for decision-making other societal needs. Uncrewed or unmanned aircraft systems (UASs) can offer data resolutions of a few centimeters at catchment-scale thus provide low-cost solution to bridge gap between sparse manual probing low-resolution satellite data. In this study, we present series measurements using different UAS platforms throughout winter Finnish subarctic site...
The Nordic countries have an intermediate climate with actual four seasons. weather here varies from summer hot to winter, freezing rain and snow all the water elements between them. In this paper, we will investigate challenges for Unmanned Aircraft System operations. We classified them into technological operational categories. a recent white MIT Lincoln Laboratory concluded that drone pilots needed account ten parameters ensure successful flight of their uAS. see, based on our long-term...

<p>Seasonally frozen ground (SFG) occurs on ~25% of the Northern Hemisphere’s land surface, and influence SFG water, energy, solute fluxes is important in cold climate regions.  The hydrological role permafrost now being actively researched, but has been receiving less attention. Intuitively, water movement blocked by ice forming soil pores that were open to flow prior freezing. However, it shown insignificant some cases, with remaining permeable even...
Seasonal freezing and thawing can have significant effects on tailings management. Tailings delivery, depositional schemes water treatment are examples of activities that must be dealt with extra concern in sub-zero temperatures. Changes mechanical properties, drainage possibilities or embedded frozen layers arise poorly managed facilities. To avoid such consequences, a good understanding the seasonal deposit is needed. get better geothermal regime tailings, this paper presents case study...
