1/5 Drones and alluvial fans – in a study led by Aleksandra Tomczyk and published in Catena, We used time-series of UAV data to map & quantify annual changes in periglacial alluvial fans in Svalbard: doi.org/10.1016/j.catena.202… #Geomorphology #UAV #ArcticResearch #WNGIG @UAM_Poznan
4/5 Permafrost degradation plays a massive role: We observed significant ground collapse linked to thermoerosion in most of the studied fans. This process highlights the critical impact of warming on Arctic stability #Permafrost #Geomorphology
5/5 UAVs provide a significant advantage over high-res satellite data - Our cm-scale elevation models and orthomosaics captured changes invisible to satellites #DEM #GIS #RemoteSensing
Thank you @NCN_PL for funding the research and IDUB @UAM_Poznan for covering OA fees!
One week left!: PhD Opportunity in in recreation ecology, geomorphology, and GIS is available at AMU Poznan, Poland, within the project: “Geomorphological effects of tourism and recreation: quantification and monitoring of trail impacts in mountain areas”: usosirk.amu.edu.pl/en-gb/off…
#GIS #PhD #recreationEcology #trails #drones #UAV #geomorphology
Application deadline: 15 September 2024
Application is through the recruitment system:
usosirk.amu.edu.pl/en-gb/off…
We invite applications from candidates interested in tourism and recreation, GIS, geomorphology and remote sensing. Applicants must hold a Master's degree at the time of document submission.
PhD candidates are enrolled at Adam Mickiewicz University (AMU) Doctoral School of Natural Sciences (phdstudies.amu.edu.pl/snp/?l…), which provides education, contact with other PhD students and opportunities to gain additional skills (courses are taught in English).
In this project, we will develop and test a novel framework for high-resolution mapping and monitoring of recreational impacts in mountain areas to derive spatially coherent information about indicators of recreational trail conditions.

1/5 New paper about short-term dynamics of proglacial landforms at Kvíárjökull, SE Iceland by @UAM_Poznan PhD student Szymon Śledź, Dave Evans (@GeogDurham) and myself published in Land Degradation and Development doi.org/10.1002/ldr.4865 #GlacialGeomorphology #Iceland
4/5 The average annual change in volume as derived from land surface lowering ranged from −0.06 m a−1 in a relatively stable area of kame terrace staircase to −0.82 m a−1 for the ice-cored hummocky moraine complex.
3/5 Compared with long-term research in this foreland since 1945, our results confirm the ongoing degradation of ice-cored moraine and outwash complexes visible and quantifiable by using land surface collapse, at variable rates related to buried ice volume and age of deglaciation
2/5 Drone data (2014-2022), historical aerial photographs (1945-2003) and satellite images (2011-2022) combined with several seasons of fieldwork have been used to quantify changes in the proglacial landscape of Kvíárjökull – a temperate glacier in SE Iceland.
1/5 Drones and recreational trails: Our new study led by Aleksandra Tomczyk has been just published in the International Journal of Applied Earth Observation and Geoinformation: doi.org/10.1016/j.jag.2023.1… #recreationEcology #UAV #GIS
4/5 The study was a collaborative effort by Noah Creany & Chris Monz (Utah State University), Francisco Javier Ancin-Murguzur (UiT-The Arctic University of Norway), Aleksandra Tomczyk & myself (Adam Mickiewicz University).
5/5 The paper is entitled: “The application of unmanned aerial vehicle (UAV) surveys and GIS to the analysis and monitoring of recreational trail conditions,” and the full text (open access) can be found here: sciencedirect.com/science/ar…
