Prehospital time and mortality in polytrauma patients: a retrospective analysis by E. Berkeveld, Z. Popal, P. Schober, W. P. Zuidema, F. W. Bloemers, G. F. Giannakopoulos

“…However, the outcome for severely injured patients is not clear yet, as little data is available from prehospital systems with both Emergency Medical Services (EMS) and physician staffed Helicopter Emergency Medical Services (HEMS). Therefore, the aim was to investigate the association between prehospital time and mortality in polytrauma patients in a Dutch level I trauma center. …”

Mapping avalanches with satellites – evaluation of performance and completeness by E. D. Hafner, F. Techel, F. Techel, S. Leinss, Y. Bühler

“…We examine manually mapped avalanches from two avalanche periods in 2018 and 2019 for an area of approximately 180 km<span class="inline-formula">²</span> around Davos, Switzerland, relying on ground- and helicopter-based photographs as ground truth. For the quality assessment, we investigate the probability of detection (POD) and the positive predictive value (PPV). …”

Assessing the Impacts of Species Composition on the Accuracy of Mapping Chlorophyll Content in Heterogeneous Ecosystems by Bing Lu, Yuhong He

“…In addition, many previous studies have used one universal model built with data of all species for mapping chlorophyll of the entire study area, which did not fully consider the impacts of species composition on the accuracy of chlorophyll estimation (i.e., establishing species-specific chlorophyll estimation models may generate higher accuracy). In this study, helicopter-acquired high-spatial resolution hyperspectral images were acquired for species classification and species-specific chlorophyll content estimation. …”

Recent Harp and Hooded Seal Pup Production Estimates in the Greenland Sea Suggest Ecology-Driven Declines by Martin Biuw, Tor Arne Øigård, Kjell Tormod Nilssen, Garry Stenson, Lotta Lindblom, Michael Poltermann, Martin Kristiansen, Tore Haug

“…One fixed-wing aircraft was used for large-area reconnaissance flights to identify the whelping concentrations and to carry out photographic surveys along systematic transects over the whelping areas. A helicopter, operated from an ice-going vessel, flew more localised reconnaissance flights, deployed GPS beacons within the detected whelping concentrations to monitor ice movements, and determined the proportion of pups in specific age-related developmental stages. …”
