Development of a handheld integrating sphere snow grain sizer (HISSGraS)
Annals of GlaciologyWe developed a Handheld Integrating Sphere Snow Grain Sizer (HISSGraS) for field use to measure the specific surface area (SSA) of snow. In addition to snow samples, HISSGraS can directly measure snow surfaces and snow pit walls.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Diurnal variations in the UV albedo of arctic snow [PDF]
Atmospheric Chemistry and Physics, 2008 The relevance of snow for climate studies is based on its physical properties, such as high surface reflectivity. Surface ultraviolet (UV) albedo is an essential parameter for various applications based on radiative transfer modeling.

River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Tensions in Fostering Student Epistemic Agency Through Sensemaking in Elementary Science
Journal of Research in Science Teaching, EarlyView.ABSTRACT Recent reforms in science education emphasize engaging students in authentic sensemaking practices. Central to this vision is positioning students as epistemic agents who generate questions, negotiate ideas, and co‐construct scientific understanding. Yet, classroom realities reveal persistent tensions in implementing these ideals, particularly

, 2022 Sunlit snow is photochemically active and plays a key role in the exchange of gas phase species between the cryosphere and the atmosphere. Bromine (Br), Iodine (I) and Mercury (Hg) can be photoactivated by the UV radiation and released from the snowpack ...

Meteoritics &Planetary Science, EarlyView.Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Elevation shapes alpine snow algal blooms and their influence on albedo reduction
New Phytologist, EarlyView.Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.
