seabed

The dredging of the area is expected to unsettle seabed which could impact the nearby reef.

How do they verify the cable is on the seabed at those depths?

That also has the advantage of giving you an interesting seabed, if you have the ability to see underwater.

This has funded a 10 year, $200-million scientific investigation in mapping and exploration of the Arctic seabed.

Beyond 1500 meters from the shoreline, builders typically lay unarmored cable directly on the seabed...

Is it possible we could use enough sand collected from the seabed to offset this sea rise?

Basically a few companies built seabed cables in southeast during the dot com boom, and then there was too much capacity for a while.

Its legs would bolted to the seabed, which I would assume is sturdy enough.

Even current levels of seabed mining are considered deeply problematic for the oceans' ecosystems (already under heavy attack from overfishing, ship traffic, waste dispersal, and species transportation).

It took two years and multiple teams (including submarine) until Titanic team came and found the blackbox and the remains of the aircraft deep on the seabed.

And I seriously doubt harvesting sea creatures will lead to anything more than the same sort of damage inflicted upon a seabed already scarred by dragnets.

Large areas of seabed in the Mediterranean and North Sea now resemble a desert – the seas have been expunged of fish using increasingly efficient methods such as bottom trawling.

In addition, they noted that sea temperatures were way out of whack, weather was "odd" everywhere they've been in the last few years (pretty much everywhere on the planet), and worryingly, that even recent charts and depth soundings were often significantly wrong, due to the seabed shifting in storms.
