Can Antarctica's shallow zoobenthos ‘bounce back’ from iceberg scouring impacts driven by climate change?
Abstract All coastal systems experience disturbances and many across the planet are under unprecedented threat from an intensification of a variety of stressors. The West Antarctic Peninsula is a hotspot of physical climate change and has experienced a dramatic loss of sea‐ice and glaciers in recent...

Abstract All coastal systems experience disturbances and many across the planet are under unprecedented threat from an intensification of a variety of stressors.
