Temporal change in deep-sea benthic ecosystems: a review of the evidence from recent time-series studies ArchiMer

J.; Perez, T.; Ruhl, H.; Sarrazin, Jozee; Soltwedel, T.; Soto, E. H.; Thatje, S.; Tselepides, A.; Van Gaever, S.; Vanreusel, A..
Societal concerns over the potential impacts of recent global change have prompted renewed interest in the long term ecological monitoring of large ecosystems The deep sea is the largest ecosystem on the planet the least accessible and perhaps the least understood Nevertheless deep sea data collected over the last few decades are now being synthesised with a view to both measuring global change and predicting the future impacts of further rises in atmospheric carbon dioxide concentrations For many years it was assumed by many that the deep sea is a stable habitat buffered from short term changes in the atmosphere or upper ocean However recent studies suggest that deep seafloor ecosystems may respond relatively quickly to seasonal inter annual and decadal...

Before and after wasting disease in common eelgrass Zostera marina along the French Atlantic coasts: a general overview and first accurate mapping ArchiMer
Godet, L; Fournier, Jonathan; Van Katwijk, M; Olivier, F; Le Mao, Patrick; Retiere, C.
We examined the original manuscripts of a French national survey conducted in 1933 on the state of common eelgrass Zostera marina beds along the French Atlantic coasts during the period when wasting disease struck the entire North Atlantic population in the 1930s. Based on GIS related techniques and old sets of aerial photographs, we present the first accurate mapping of the Z. marina beds before wasting disease occurred and assess their spatial recolonization since the 1950s in the Chausey Archipelago (France), which contains large Z. marina beds. The national survey confirmed that the Z. marina beds almost totally disappeared from the French coasts during the 1930s. However, the disease symptoms seem to have begun locally a few years before. On the study...
