Fig. 6: Difference in carbon storage and response to trawling impact between sand and muddy sediments in the North Sea.
From: Long-term carbon storage in shelf sea sediments reduced by intensive bottom trawling
a, Distribution of surface sediment OC/mud measured in sand (n = 1,031) in relation to the multi-year averaged SAR. The means ± standard deviations are indicated by dots and error bars. b, Similar to a but for muddy sediments (n = 1,349). c, Relative change of OC/mud in sand between simulations with and without trawling for 50 years. d, Similar to c but for muddy sediments. The trendlines represent the best fit, with corresponding power functions and R squared.
