The sub-antarctic area key rese arch questions include: • what are the changes occurring in sub-antarctic near-shore ecosystems that are due to global change • what are the drivers of climate change impacts on sub-antarctic near-shore ecosystems • which species and/or processes are suitable for tracking the effects.
