Iceberg impacts on seabed blue carbon. (a) Iceberg grounded at South Georgia in 2004; photo courtesy of US National Ice Center. Sites 11, 12 and 13 are benthic image and trawl samples. The island in the image (left) is South Georgia and iceberg size is 75 × 41 km. (b) Correlation between sea-ice duration and blue carbon storage on the seabed around southern Adelaide Island, West Antarctic Peninsula (from data in Barnes [6,9] ). Zones are zoobenthic carbon; significant increase with increased fast-ice duration (A), no significant change (B,D), significant decrease with increased fast-ice duration (C) and depth zone where there is too little known for meaningful analysis (zone of ignorance).
