Durand, Gaël (author), van den Broeke, Michiel R. (author), Le Cozannet, Goneri (author), Edwards, Tamsin L. (author), Holland, Paul R. (author), Jourdain, Nicolas C. (author), Marzeion, Ben (author), Mottram, Ruth (author), van Calcar, C.J. (author)

Coastal areas are highly diverse, ecologically rich, regions of key socio-economic activity, and are particularly sensitive to sea-level change. Over most of the 20th century, global mean sea level has risen mainly due to warming and subsequent expansion of the upper ocean layers as well as the melting of glaciers and ice caps. Over the last...

Intercomparison of Large-Eddy Simulations of the Antarctic Boundary Layer for Very Stable Stratification

Couvreux, Fleur (author), Bazile, Eric (author), Rodier, Quentin (author), Maronga, Björn (author), Matheou, Georgios (author), Chinita, Maria J. (author), Edwards, John (author), van Stratum, Bart J.H. (author), van Heerwaarden, Chiel C. (author), Huang, Jing (author), Moene, Arnold F. (author), Cheng, Anning (author), Fuka, Vladimir (author), Basu, S. (author), Bou-Zeid, Elie (author), Canut, Guylaine (author), Vignon, Etienne (author)

In polar regions, where the boundary layer is often stably stratified, atmospheric models produce large biases depending on the boundary-layer parametrizations and the parametrization of the exchange of energy at the surface. This model intercomparison focuses on the very stable stratification encountered over the Antarctic Plateau in 2009. Here...

Long-term impacts of rising sea temperature and sea level on shallow water coral communities over a similar to 40 year period

Brown, B. E. (author), Dunne, R. P. (author), Somerfield, P. J. (author), Edwards, A. J. (author), Simons, W.J.F. (author), Phongsuwan, N. (author), Putchim, L. (author), Anderson, L. (author), Naeije, M.C. (author)

Effects of combined rising sea temperature and increasing sea level on coral reefs, both factors associated with global warming, have rarely been addressed. In this ~40 y study of shallow reefs in the eastern Indian Ocean, we show that a rising relative sea level, currently estimated at ~11 mm y−1, has not only promoted coral cover but also has...

Safety culture across cultures

Yorio, Patrick L. (author), Edwards, J. (author), Hoeneveld, D. (author)

National culture colors nearly every aspect of human behavior (Javidan et al., 2006). Despite this truism, the concept has yet to be integrated into organizational safety culture theory. The purpose of this article is to bring awareness as to how national culture can influence organizational safety culture. We do so by theorizing that the...

Large-Eddy Simulations of the Steady Wintertime Antarctic Boundary Layer

van der Linden, S.J.A. (author), Edwards, John M. (author), van Heerwaarden, Chiel C. (author), Vignon, Etienne (author), Genthon, Christophe (author), Petenko, Igor (author), Baas, P. (author), Jonker, H.J.J. (author), van de Wiel, B.J.H. (author)

Observations of two typical contrasting weakly stable and very stable boundary layers from the winter at Dome C station, Antarctica, are used as a benchmark for two centimetre-scale-resolution large-eddy simulations. By taking the Antarctic winter, the effects of the diurnal cycle are eliminated, enabling the study of the long-lived steady...
