The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Electron precipitation characteristics during isolated, compound, and multi-night substorm events [PDF]
A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound substorms consist of multiple phase ...

Reconfiguration and closure of lobe flux by reconnection during northward IMF: possible evidence for signatures in cusp/cleft auroral emissions [PDF]
Observations are presented of the response of the dayside cusp/cleft aurora to changes in both the clock and elevation angles of the interplanetary magnetic field (IMF) vector, as monitored by the WIND spacecraft.

Auroral all-sky camera calibration [PDF]
A two-step procedure to calibrate the spectral sensitivity to visible light of auroral all-sky cameras is outlined. Center pixel response is obtained by the use of a Lambertian surface and a standard 45 W tungsten lamp.

Jupyter Book as an open online teaching environment in the geosciences: lessons learned from Geo-SfM and Geo-UAV [PDF]
Together with our students, we co-created two open-access geoscientific course modules using the Jupyter Book environment. We also assessed the Jupyter Book environment, integrated with GitHub to facilitate versioning, for its suitability for co-creation

The Ice‐Free Topography of Svalbard [PDF]
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 km of thickness profiles.

Snow research in Svalbard?an overview [PDF]
This paper summarizes the most significant snow-related research that has been conducted in Svalbard. Most of the research has been performed during the 1990s and includes investigations of snow distribution, snow-melt, snow pack characteristics, remote sensing of snow and biological studies where snow conditions play an important role.
