33
for land-detached submarine canyons (Heijnen et al.):\nAbstract: 
            
34
Sediment, nutrients, organic carbon and pollutants are funnelled down 
            
35
submarine canyons from continental shelves by sediment-laden flows 
            
36
called turbidity currents, which dominate particulate transfer to the 
            
37
deep sea. Post-glacial sea-level rise disconnected more than three 
            
38
quarters of the >9000 submarine canyons worldwide from their former 
            
39
river or long-shore drift sediment inputs. Existing models therefore 
            
40
assume that land-detached submarine canyons are dormant in the 
            
41
present-day; however, monitoring has focused on land-attached canyons 
            
42
and this paradigm remains untested. Here we present the most detailed 
            
43
field measurements yet of turbidity currents within a land-detached 
            
44
submarine canyon, documenting a remarkably similar frequency (6 yr-1) 
            
45
and speed (up to 5-8 ms-1) to those in large land-attached submarine 
            
46
canyons. Major triggers such as storms or earthquakes are not 
            
47
required; instead, seasonal variations in cross-shelf sediment 
            
48
transport explain temporal-clustering of flows, and why the storm 
            
49
season is surprisingly absent of turbidity currents. As >1000 other 
            
50
canyons have a similar configuration, we propose that contemporary 
            
51
deep-sea particulate transport via such land- detached canyons may 
            
52
have been dramatically under-estimated.",
