Agulhas rings provide the principal route for ocean waters to circulate from the Indo-Pacific to the Atlantic basin. Their influence on global ocean circulation is well known, but their role in plankton transport is largely unexplored. We show that, although the coarse taxonomic structure of plankto...

L’exposition des populations des atolls de Rangiroa et de Tikehau (Polynésie française) au risque de submersion marine

Articles

Alexandre K. Magnan et al. (Aug 2, 2019)

Articles

This paper characterizes the current exposure of people leaving on the low-lying atoll reef islands to the risk of marine inundation induced by various sea-related hazards (i.e. cyclones, distant swells and local storms). It offers one of the rare scientific studies that go beyond the general assert...

Fate of Mediterranean Scleractinian Cold-Water Corals as a Result of Global Climate Change. A Synthesis

Books and book chapters

Cornelia Maier et al. (2019)

Books and book chapters

This chapter addresses the question as to how Mediterranean cold-water corals might fare in the future under anthropogenically-induced global climate change. The focus on three most prominent scleractinian cold-water corals species, the two branching and habitat-forming forms Madrepora oculata, Loph...

Dynamics of benthic metabolism, O2, and pCO2 in a temperate seagrass meadow

Textual materials

Peter Berg et al. (2019)

Textual materials

Seagrass meadows play an important role in “blue carbon” sequestration and storage, but their dynamic metabolism is not fully understood. In a dense Zostera marina meadow, we measured benthic O2 fluxes by aquatic eddy covariance, water column concentrations of O2, and partial pressures of CO2 (pCO2)...

Processing BGC-Argo pH data at the DAC level

Textual materials

Kenneth S. Johnson et al. (Apr 9, 2018)

Textual materials

Seawater proton concentration is a master variable that controls the air-sea gas exchange of CO2, the ability of organisms to produce calcium carbonate shells, and that tracks the production and respiration of organic carbon as CO2 is removed or added to water by biological processes. The proton co...

Role of macrophytes in the restoration of lagoon environments : ecological succession

Thesis

Ines Le Fur (Mar 16, 2018)

Thesis

The growing awareness of the negative impacts of the degradation of the water quality in coastal lagoons because of eutrophication has resulted in public action aiming at the reduction of the nutrient loadings into these lagoons. Hence, some of these coastal lagoons are currently undergoing ecologic...

Leçons tirées du cyclone Pam au Vanuatu (Mélanésie) : aléas côtiers, crues éclairs et dommages

Articles

Tony Rey et al. (Dec 31, 2017)

Articles

An extremely destructive category 5 cyclone (Saffir-Simpson), Tropical Cyclone Pam, struck Vanuatu on the evening of 13 March 2015, causing serious damage to infrastructure across the capital Port‑Vila. We studied the coastal change, flash flood and damages effects three months after super cyclone....

Effects of in situ CO 2 enrichment on epibiont settlement on artificial substrata within a Posidonia oceanica meadow

Articles

T.E. Cox et al. (Dec, 2017)

Articles

Alterations to colonization or early post-settlement stages may cause the reorganization of communities under future ocean acidification conditions. Yet, this hypothesis has been little tested by in situ pH manipulation. A Free Ocean Carbon Dioxide Enrichment (FOCE) system was used to lower pH by a...

11. Réchauffement et acidification des eaux

Books and book chapters

Serge Planes (Oct 19, 2017)

Books and book chapters

Le réchauffement et l’acidification des océans trouvent leurs origines dans le changement climatique, dans lequel s’inscrit toute la planète, et qui a été largement décrit depuis quelques décennies. L’effet de serre*, principale cause du changement climatique, correspond au piégeage des radiations s...

Combined effects of ultraviolet radiation and global warming on Scleractinian corals

Thesis

Lucile Courtial (Sep 29, 2017)

Thesis

Scleractinian corals mainly grow in the shallow euphotic zone, exposed to ultraviolet radiation (UVR), the most harmful part of the solar radiation. UVR increases with climate change and adds to the different environmental pressures that corals are facing. The aims of this thesis were to 1) better u...

Local and regional drivers of headwater streams metabolism : insights from the first AIL collaborative project

Articles

Ada Pastor et al. (2017)

Articles

Streams play a key role in the global biogeochemical cycles, processing material from adjacent terrestrial systems and transporting it downstream. However, the drivers of stream metabolism, especially those acting at broad spatial scales, are still not well understood. Moreover, stream metabolism ca...

Changements climatiques, changements du littoral et évolution de la vulnérabilité côtière au fil du temps : comparaison de territoires français, canadien et sénégalais

Articles

Sebastian Weissenberger et al. (Dec 20, 2016)

Articles

The vulnerability of coastal zones to the impacts of climate change and risks is the result of the synergy of natural and human impacts on the natural environment, which together create a vulnerable socio-ecological system. In order to account for that duality, theoretical approaches such as the exp...
