There's a team who live-stream their dives with a deep-sea ROV, and being along for the ride when they discovered a whale fall in 2019 will always be something I remember very fondly. They returned in 2020 to document the changes to the carcass. https://www.youtube.com/watch?v=uvSNgwIqvrM

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.
