Impact of Bottom Trawling on Deep-Sea Sediment Properties along the Flanks of a Submarine Canyon
Figure 5
Trawled/untrawled and inshore/offshore gradients in the flanks of La Fonera Canyon.
Excess 210Pb inventories (A); sand content in the upper 10 cm of the sediment column (B); interpretative summary of the results (C). Cropped bars in the 210Pb inventories indicate that the 210Pb supported level was not reached and consequently these inventories represent lower estimates of the excess 210Pb accumulated at each site. The arrow indicates the approximate position of the main along-shelf sediment transport. Coordinates are East and North degrees/minutes for longitude and latitude respectively.
