Fig. 5: Difference of carbon content in mud between measured field data and simulations with and without trawling impacts in the North Sea.
From: Long-term carbon storage in shelf sea sediments reduced by intensive bottom trawling
a, Measured OC/mud and simulation without trawling impact for 50 years (No trawling, n = 2,380). b, Similar to a but for simulation with trawling impact. c, Relative change of OC/mud between simulations with and without trawling for 10 years. The means ± standard deviations are indicated by dots and error bars. d, Similar to c but for 50 years. The trendlines in c and d represent the best fit, with corresponding power functions and R squared.
