Abstract Oxygen-isotope thermometry played a critical role in the rise of modern geochemistry and remains extensively used (bio-)geoscience. Its theoretical foundations rest on assumption that 18 O/ 16 O partitioning among water carbonate minerals primarily reflects thermodynamic equilibrium. However, after decades research, there is no consensus true equilibrium fractionation between calcite ( α cc/w ). Here, we constrain relations linking temperature, , clumped isotopes Δ 47 ) based...
Plastic contamination is now recognized as one of the most serious environmental issues for oceans. Both macro- and microplastic debris are accumulating in surface deep waters. However, little known about their impact on marine ecosystems especially deep-sea reefs built by emblematic cold-water corals. The aim this study was to investigate whether plastics affected growth, feeding behaviour main engineer species, Lophelia pertusa. Our experiments showed that both micro- macroplastics...
Hydrothermal circulation at ultramafic‐hosted sites supports a large variety of high‐ and low‐temperature hydrothermal vents associated ecosystems. The discovery abundant fossil vesicomyid thyasirid shell accumulations the ridge crest, approximately 2.5 km east active Rainbow vent field on Mid‐Atlantic Ridge (MAR, 36°13′N), increased our knowledge regarding diversity communities slow spreading ridges. Bivalve molluscs family Vesicomyidae were represented by genus Phreagena . Here we present...
Oceanic plastic pollution is of major concern to marine organisms, especially filter feeders. However, limited known about the toxic effects weathered microplastics instead pristine ones. This study evaluates polystyrene microplastic on a filter-feeder amphioxus under starvation conditions via its exposure previously deployed in natural seawater allowing for development mature biofilm (so-called plastisphere). The focused integration physiological, histological, biochemical, molecular, and...
The constraint of temperature evolution in coastal environments is an important factor deciphering the Earth’s global climatic history. In this study, we reconstruct sea-surface palaeotemperatures from oxygen stable isotope compositions four marine molluscs families Paris Basin during Palaeogene. combination several taxa living different used to limit uncertainties related influence salinity variations on palaeotemperature estimations. One family bivalves (oysters) and three gastropods...
Cold-water corals are threatened by global warming, especially in the Mediterranean Sea where they live close to their upper known thermal limit (i.e. 13°C), yet response rising temperatures is not well known. Here, temperature effects on Lophelia pertusa and Madrepora oculata holobionts host its associated microbiome) were investigated. We found that at warmer seawater (+2°C), L. showed a modification of microbiome prior change behaviour, leading lower energy reserves skeletal growth,...
Research on the biology and ecology of cold-water corals (CWCs) is still in its infancy. The growth patterns CWCs their natural environments are poorly known. Growth rate investigations these deep-sea reef builder species needed to predict recovery times following damage ecosystems. This study investigates a new approach for analysing CWC rate, suitable situ application. Lophelia pertusa Madrepora oculata (Scleractinian) were collected from Lacaze-Duthiers canyon northwestern Mediterranean...
The ostracod fauna from the outcroup "la falunière" of Grignon (Lutetian, Paris Basin): stratigraphical implications.The rehabilitation (shell marl pit) allowed for first time to take an almost complete section Basin Middle Lutetian under its uncimented facies. It was opportunity undertake sedimentological and paleontological studies. This publication presents results ostracode study. More than 6000 valves or carapaces were collected 87 species distinguished. Three new are described :...
As their tropical analogues, cold-water colonial corals are engineer species that create complex habitats among the richest in deep-sea biodiversity (Rogers 1999). Although living deeper waters than (from 5 m to over 3,000 depth), will soon face cumulative threats of ocean warming and acidification (Foley et al. 2010). counterparts, specific host-bacteria associations have been highlighted (Neulinger 2008, Meistertzheim 2016, Kellog 2017). But due difficulty sampling, detailed knowledge...
