Documentaries showing footages of ecosystems forming around Whale carcasses at the bottom of the oceans are fascinating.
The falls in this article though seem so different due to their depth and age, and especially surprising to me is the sedimentation rate in that area, ~less than half a centimeter per 1000 years. I always imagine ocean sedimentation to be substantial and uniform, but it makes sense that currents and local ecology would play a huge role.
