Next month, a 🇺🇸 interagency team is headed to the Aleutian Islands, AK aboard the R/V Atlantis to characterize deep sea enviros + minerals (building off recent Saildrone mapping efforts). 🧪🌊

AT50-38: mapping/ CTDs/ eDNA/ Alvin dives

Stay tuned!
(Bonus: all data will be public)
Fast-forward 4 years and a ton of research later, and my initial estimate remains the same--we've seen ~0.001% of the deep seafloor, an area approx the same as the size of Rhode Island.

How little we’ve seen: A visual coverage estimate of the deep seafloor
In decades of deep-sea exploration, humans have observed only 0.001% of the deep seafloor, leaving 66% of planet Earth unseen.
