Seawater carbonate chemistry and calcification during experiments with maerl beds, 2007, supplement to: Martin, Sophie; Clavier, Jacques; Chauvaud, Laurent; Thouzeau, Gérard (2007): Community metabolism in temperate maerl beds. I. Carbon and carbonate fluxes. Marine Ecology Progress Series, 335, 19-29
Maerl community respiration, photosynthesis and calcification were measured seasonally in the Bay of Brest (France). The dynamics of oxygen, carbon and carbonate fluxes at the water-sediment interface were assessed using benthic chambers. Community respiration (CR) fluctuated in accordance with the...
