Journal ArticleDOI
January 2016 extensive summer melt in West Antarctica favoured by strong El Niño
Julien P. Nicolas,Andrew M. Vogelmann,Ryan C. Scott,Aaron B. Wilson,Maria P. Cadeddu,David H. Bromwich,Johannes Verlinde,Dan Lubin,Lynn M. Russell,Colin Jenkinson,Heath Powers,Maciej Ryczek,Gregory Stone,Jonathan D. Wille +13 more
TL;DR: An episode of extensive and prolonged surface melting observed in the Ross Sea sector of the West Antarctic Ice Sheet in January 2016 is reported, likely favoured by the concurrent strong El Niño event.
Journal ArticleDOI
Responses of two semiarid conifer tree species to reduced precipitation and warming reveal new perspectives for stomatal regulation
Núria Garcia-Forner,Henry D. Adams,Sanna Sevanto,Adam D. Collins,Lee T. Dickman,Patrick J. Hudson,Melanie J. B. Zeppel,Michael W. Jenkins,Heath Powers,Jordi Martínez-Vilalta,Nate G. McDowell +10 more
TL;DR: It is found that reductions in stomatal conductance and assimilation by heat and drought were more frequent during relatively moist periods, but these effects were not exacerbated in the combinedHeat and drought treatment.

TL;DR: The MOSAiC program as mentioned in this paper was organized into four subgroups: atmospheric state, clouds and precipitation, gases and aerosols, and energy budgets, using a variety of approaches, and across multiple scales.
Journal ArticleDOI
Experimental drought and heat can delay phenological development and reduce foliar and shoot growth in semiarid trees.
Henry D. Adams,Adam D. Collins,Samuel P. Briggs,Michel Vennetier,L. Turin Dickman,Sanna Sevanto,Núria Garcia-Forner,Heath Powers,Nate G. McDowell +8 more
TL;DR: The potential for delayed phenological development and reduced growth with higher temperatures and drought in tree species that are vulnerable to drought is demonstrated and potential mechanistic links to physiological stress responses are revealed.
Journal ArticleDOI
Unsaturation of vapour pressure inside leaves of two conifer species
Lucas A. Cernusak,Nerea Ubierna,Michael W. Jenkins,S. R. Garrity,Thom Rahn,Heath Powers,David T. Hanson,Sanna Sevanto,Suan Chin Wong,Nate G. McDowell,Graham D. Farquhar +10 more
TL;DR: The results refute the longstanding assumption of saturated vapour pressure in plant leaves under all conditions, based on coupled measurements of leaf gas exchange and the stable isotope compositions of CO2 and water vapour passing over the leaf.
