Estimating 1992-2000 average active layer thickness on the Alaskan North Slope from remotely sensed surface subsidence
TL;DR: In this article, a retrieval algorithm was developed to estimate long-term average active layer thickness (ALT) using thaw-season surface subsidence derived from spaceborne interferometric synthetic aperture radar (InSAR) measurements.
Journal ArticleDOI

TL;DR: This article examined natural and anthropogenic controls on terrestrial evapotranspiration (ET) changes from 1982 to 2010 using multiple estimates from remote sensing-based datasets and process-oriented land surface models.
Journal ArticleDOI
Increased water-use efficiency and reduced CO2 uptake by plants during droughts at a continental scale

TL;DR: The 13C/12C stable isotope ratio in atmospheric CO2 is analysed to provide new observational evidence of the impact of droughts on the WUE across areas of millions of square kilometres and spanning one decade of recent climate variability, suggesting that current climate models may underestimate carbon–drought feedbacks.
Permafrost stores a globally significant amount of mercury

TL;DR: In this article, the authors used a network of eddy covariance towers in Brazil coupled with ancillary measurements to address two main questions: first, how do mechanisms of water supply (indicated by root depth and groundwater) and vegetation water demand (defined by stomatal conductance and intrinsic water use efficiency) control evapotranspiration (E) along broad gradients of climate and vegetation from equatorial Amazonia to Cerrado, and how do these inferred mechanisms of supply and demand compare to those employed by a suite of ecosystem models?
