[1] During austral summer 2003, we tracked a patch of surface water infused with the tracer sulfur hexafluoride, but without addition of Fe, through subantarctic waters over 10 days in order to characterize and quantify algal Fe pools and fluxes to construct a detailed biogeochemical budget. Nutrient profiles characterized this patch as a high-nitrate,(More)
Biodiversity and species abundance in coral reef ecosystems are controlled by structural complexity (Graham and Nash 2013), which is being impacted by reduced net reef framework accretion resulting from anthropogenic stressors (Kennedy et al. 2013). However, evidence verifying changes in benthic reef communities via long-term visual monitoring is rare. In(More)
Biological dinitrogen (N2) fixation (diazotrophy, BNF) relieves marine primary producers of nitrogen (N) limitation in a large part of the world oceans. N concentrations are particularly low in tropical regions where coral reefs are located, and N is therefore a key limiting nutrient for these productive ecosystems. In this context, the importance of(More)
