Late Holocene moisture variability in Arctic Alaska from chitin δ18O
Boreas, EarlyView.Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Remote Sensing, 2015 Surface albedo is one of the key controlling geophysical parameters in the surface energy budget studies, and its temporal and spatial variation is closely related to the global climate change and regional weather system due to the albedo feedback ...

The Acts of Eadburg: drypoint additions to Oxford, Bodleian Library, MS Selden Supra 30
Early Medieval Europe, EarlyView.In 1913, two drypoint additions were identified in Oxford, Bodleian Library, MS Selden Supra 30 (SS30), an eighth‐century Southumbrian copy of the Acts of the Apostles. It was suggested that these additions, cut into the membrane of p. 47, were abbreviations of the Old English female name, Eadburg. Just over a century later, many more drypoint markings

Monitoring surface albedo change with Landsat
Geophysical Research Letters, 1977 A pronounced decrease of the surface albedo (reflectivity) has been observed in an area in the Northern Sinai, fenced‐in in the summer of 1974. Analysis of the LANDSAT Multispectral Scanner System digital data from an April 1977 pass indicates a reduction in the albedo in the exclosure by Δa = 0.06, or 13%, as compared to the outside, which continues ...

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites
Meteoritics &Planetary Science, EarlyView.Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Remote Sensing, 2015 To evaluate and improve the quality of land surface albedo products, validation with ground measurements of albedo is crucial over the spatially and temporally heterogeneous land surface. One of the essential steps for satellite albedo product validation

Reduced snow cover at the alpine treeline: resistance and recovery of saplings
New Phytologist, EarlyView.Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced
