DOI: 10.1002/lol2.10046
Abstract: Dinitrogen (N2) fixation is the source of all biologically available nitrogen on earth, and its presence or absence impacts net primary production and global biogeochemical cycles. Here, we report rates of 3.5–17.2 nmol N L−1… read more here.

DOI: 10.1016/j.catena.2021.105706
Abstract: Abstract Perchlorate (ClO4−), a persistent inorganic compound, has harmful effects on human health. Natural ClO4− is formed in the atmosphere and enters into the surface environment through deposition. However, the knowledge on the occurrence, spatial… read more here.

DOI: 10.1016/j.rse.2018.02.060
Abstract: Abstract As high-latitudes warm, permafrost thaws, and the hydrological cycle accelerates, ground-based monitoring of riverine organic matter may be supplemented by satellite remote sensing during ice-free conditions. Recent programs, namely the Arctic Great Rivers Observatory,… read more here.

DOI: 10.1029/2018gl079734
Abstract: We present a first version of the Svalbard ice-free topography (SVIFT1.0) using a mass conserving approach for mapping glacier ice thickness. SVIFT1.0 is informed by more than 1 million point measurements, totalling more than 8,700… read more here.

DOI: 10.1111/ecog.03018
Abstract: The Antarctic Peninsula is among the places on Earth that registered major warming in the last 60 years. Massive ice losses, represented by glacier retreat, ice-shelf collapses and sea-ice reduction are among the main impacts… read more here.

DOI: 10.1111/ppl.13865
Abstract: Conifer (Pinaceae) needles are the most frost-hardy leaves. During needle freezing, the exceptional leaf anatomy, where an endodermis separates the mesophyll from the vascular tissue, could have consequences for ice management and photosynthesis. The eco-physiological… read more here.
