Description: Sea temperature is a major environmental factor controlling the distribution and metabolism of benthic organisms. It is well established that cold-water species from both deepsea and polar regions are adapted to low ambient temperatures but mostly exhibit a rather narrow physiological temperature tolerance (Clarke & Fraser 2004). Hence, even small changes in temperature are likely to have a large effect on the metabolism of those species and, at a community level, might alter the partitioning of the benthic carbon and energy flow pattern at a community level (Piepenburg et al. 1996). Moreover, as climate change will not only lead to a pronounced temperature rise but also to a significant decrease in pH (ocean acidification) and, at local scales, salinity (e.g., the temperatureinduced freshwater release), the synergetic impacts of these interacting abiotic parameters on one or a few leverage species are expected to cause sweeping community-level changes (Harley et al. 2006). As such shifts are difficult to study and predict at this level, particularly in remote cold-water environments, we propose to start with examining the short-term response (at a level of hours to days) of the metabolism of benthic organisms to changes in temperature, salinity and pH, combining an experimental approach and a small-scale field study.
