Warming and Oxygen Change Below the Surface
The deep ocean is not insulated from climate change, although its sampling gaps complicate local predictions. Heat and oxygen records must be read by depth and basin.

Potential impacts differ between nodules, seamount crusts, and vent sulfides. Baseline data, sediment disturbance, and recovery time are central questions.

Towed gear can disturb the seabed. Corals and sponges are especially relevant because complex, stable habitats can take a long time to rebuild.

Unknown species are not the only reason to protect a habitat. Structure, connectivity, and ecological function can matter while taxonomy is still catching up.
