The timing of annual events such as reproduction is a critical component of how free‐living organisms respond to ongoing climate change. This may be especially true in the Arctic, which is disproportionally impacted by climate warming. Here, we show that Arctic seabirds responded to climate change by moving the start of their reproduction earlier, coincident with an advancing onset of spring and ...

<p>“Looking to the North” is a unique cartographic exhibition currently on display at the Polar Museum in Tromsø. The exhibition features some of the most spectacular printed maps of the northern regions, among them a copy of the first printed map of the European Far North, published in Ulm 1482, in present-day Germany. UiT The Arctic University of Norway boasts one of the finest collections of ...

In this paper we study how GPS, GLONASS, and Galileo navigation signals are compromised by strong irregularities causing severe phase scintillation (σϕ>1) in the nightside high-latitude ionosphere during a substorm on 3 November 2013. Substorm onset and a later intensification coincided with polar cap patches entering the auroral oval to become auroral blobs. Using Global Navigation Satellite Systems ...

High mountain ecosystems and their biota are governed by low-temperature conditions and thus can be used as indicators for climate warming impacts on natural ecosystems, provided that long-term data exist. <p>We used data from the largest alpine to nival permanent plot site in the Alps, established in the frame of the Global Observation Research Initiative in Alpine Environments (GLORIA) on Schrankogel ...

Importance Operations for lumbar spinal stenosis is the most often performed surgical procedure in the adult lumbar spine. This study reports the clinical outcome of the 3 most commonly used minimally invasive posterior decompression techniques.<p> <p>Objective To compare the effectiveness of 3 minimally invasive posterior decompression techniques for lumbar spinal stenosis. <p>Design, ...

The configuration of the marine-based NW Fennoscandian ice sheet during the Last Glacial Maximum (LGM) and deglaciation is reconstructed using detailed swath bathymetry and high-resolution seismic data. The investigated area covers about 10,000 km² of the continental shelf off Troms, northern Norway. Large scale morphology is characterized by cross-shelf troughs, coast-parallel troughs ...

Background: Virtually all living organisms, including microbes and humans, depend on iron to survive and grow. During an infection, the plasma level of iron and several iron-related proteins change substantially. We hypothesized that iron and iron-related proteins could predict short- and long-term outcomes in community-acquired pneumonia.<p> <p>Methods: Blood samples from a prospective cohort ...

Marine traffic is increasing in the Arctic Region. As ice in the Arctic Region retracts, opportunities for the marine industry increase. This relates to the fishing industry, which is moving further into the Arctic Seas, the shipping industry, which is using the Northern Sea Route, particularly for transporting liquefied natural gas, and the cruise industry, which is transporting passengers to ...

The small-aperture Spitsbergen seismic array (SPITS) has been in continuous operation at Janssonhaugen for decades. The high-Arctic location in the Svalbard archipelago makes SPITS an ideal laboratory for the study of cryoseisms, a nontectonic class of seismic events caused by freeze processes in ice, ice–soil, and ice–rock materials. We extracted a catalog of > 100 000 events from the nearly ...

Objective The aim of the current study was to assess the relation between occupational exposure to solvents and the risk of acute myeloid leukemia (AML).<p> <p>Methods Altogether, this study comprises 15 332 incident cases of AML diagnosed in Finland, Norway, Sweden, and Iceland from 1961–2005 and 76 660 controls matched by year of birth, sex, and country. Occupational records were linked with ...
