Paull 2014 <p><span>Remotely operated and autonomous underwater vehicle technologies were used to image and sample exceptional deep sea outcrops where an &sim;100-m-thick section of turbidite beds is exposed on the headwalls of two giant submarine scours on Eel submarine fan, offshore northern California (USA). These outcrops provide a rare opportunity to connect young deep-sea turbidites with their feeder system.&nbsp;</span>¹⁴<span>C measurements reveal that from 12.8 ka to 7.9 ka, one turbidite was being emplaced on average every 7 yr. This emplacement rate is two to three orders of magnitude higher than observed for turbidites elsewhere along the Pacific margin of North America. The turbidites contain abundant wood and shallow-dwelling foraminifera, demonstrating an efficient connection between the Eel River source and the Eel Fan sink. Turbidite recurrence intervals diminish fivefold to &sim;36 yr from 7.9 ka onward, reflecting sea-level rise and re-routing of Eel River sediments.</span></p> application/pdf 10.1130/G35768.1 en Geological Society of America Sub-decadal turbidite frequency during the early Holocene: Eel Fan, offshore northern California article
