Hi, Kamron– I was mostly talking about new sediment, since we were talking about rivers from Alaska and the Aleutian trench. I do not know whether that would get dragged under by subduction, being loose, but it would not greatly surprise me. Bits of ooze may get caught in between where the "seal" between plates is being formed, while most is being scraped off as you expect (but ready to try to get caught again). Older, deeper sediments would be lithified and just as good as the next rock at resisting being scraped off. That has to be the bulk of the near-Japan stuff. –Doug
