Propithecus verreauxi demography spanning 40 years at Bezà Mahafaly Special Reserve, southwest Madagascar [PDF]

open access: yesScientific Data
The diverse, highly endemic flora and fauna of Madagascar make it a priority for research and conservation. Lemurs, the island’s endemic primates, exhibit a distinctive array of biological, behavioral and demographic traits.

A probabilistic seabed–ice keel interaction model [PDF]

open access: yesThe Cryosphere, 2022
Landfast ice is a common coastal feature in the Arctic Ocean and around the Antarctic continent. One contributing and stabilizing mechanism is the grounding of sea ice ridges in shallow water.

Changement climatique [PDF]

open access: yesNorois, 2015
La mobilisation autour de la conference Paris Climat 2015 (COP 21) est l'occasion de mettre en relief la vulnerabilite des milieux et des populations du Sud face au rechauffement climatique. Certaines regions de la zone intertropicale en subissent deja les effets, que ce soient les vagues de chaleur au Sahel, la perturbation des systemes de mousson, la

On the calculation of normalized viscous–plastic sea ice stresses [PDF]

open access: yesGeoscientific Model Development, 2020
Calculating and plotting the normalized states of stress for viscous–plastic sea ice models is a common diagnostic for evaluating the numerical convergence and the physical consistency of a numerical solution. Researchers, however, usually do not explain

What historical landfast ice observations tell us about projected ice conditions in Arctic archipelagoes and marginal seas under anthropogenic forcing [PDF]

open access: yesThe Cryosphere, 2018
Arctic landfast ice extent and duration are examined from observations, ice assimilations, ocean reanalyses and coupled models. From observations and assimilations, it is shown that in areas where landfast ice conditions last more than 5 months the first-

Comment la région Nouvelle Aquitaine anticipe le changement climatique ? [PDF]

open access: yesSciences, Eaux & Territoires, 2017
Au travers d’Acclimaterra, le comité scientifique régional sur le changement climatique en Nouvelle Aquitaine, la région Nouvelle Aquitaine conduit depuis 2011 une démarche originale de veille sur le changement climatique régional et de prospective pour ...

Using Icepack to reproduce ice mass balance buoy observations in landfast ice: improvements from the mushy-layer thermodynamics [PDF]

open access: yesThe Cryosphere
Icepack (v1.1.0) – the column thermodynamics model of the Community Ice CodE (CICE) version 6 – is used to assess how changing the thermodynamics from the Bitz and Lipscomb (1999) physics (hereafter BL99) to the mushy-layer physics impacts the model ...

Impact of non-normal flow rule on linear kinematic features in pan-Arctic ice-ocean simulations [PDF]

open access: yesThe Cryosphere
The standard sea ice viscous-plastic (VP) rheology is based on an elliptical yield curve and a normal flow rule. This formulation implies that the post-failure deformations are always normal to the yield curve. A drawback of this is that modifications to

Les tourbières de la République Démocratique du Congo : entre la protection et l’exploitation, sur quel pas danser ? [PDF]

open access: yesMouvements et Enjeux Sociaux, 2022
Actuellement, le monde vit un changement climatique qui ne dit pas son nom. Celui-ci changement résulte des activités humaines et affecte tous les aspects de la vie présente et future et devient automatiquement un défi auquel le monde est appelé à faire ...
