Lake Abyss

There is a very deep pit near the middle of our main lake.

Introduction:

This is where deepest-sea training is carried out.  Experienced divers and submariners can gain access to this shaft extending down from the center of the bottom of Inisfree’s main lake.  ICVs always accompany them, as it is a most-daunting activity and feature of the city.

The Why:

What’s the purpose of an ultra-deep man-made body of water like this… in a city based on pleasurable interactions between surface-dwellers?

  1. Millions of sea-people (actual mer-folk; Atlanteans, mermaids, sea-nymphs, Sirens, etc.) call Inisfree their 2nd home, or at least one of their all-time favorite vacation-getaways/homes.
  2. Many worlds we go on expeditions to have oceans greater in volume/capacity than the Earth‘s.
  3. Some ancient ruins are on the bottom of Earth’s oceans (and the ocean floors of other worlds), and we always prefer to train in the totally-controlled immortality-guaranteeing environment that is our home here.  (Even though lands can be asked/made to rise back up, and oceans lower back down, while so much is still, for now, submerged on Earth, it makes a lot of sense to have a facility such as this.)

Dimensions:

This part of our terrain is some 3,500′ deep –roughly 65% of a mile.  It is 730/+’ deeper than the SCUBA City tanks.

Its diameter is a few hundred feet at the top (on the floor/bed of our main lake), narrowing slightly along the way down.

Pressure:

For calculations/estimates, use:

By altitude/depth:

  • surface (ground-level in Inisfree; ~9,240′ above ocean-level):  ~10 PSI
  • ocean-level (outside Inisfree):  14.7 PSI
  • 500′ depth (below the lake-surface in Inisfree):  ~220 PSI
  • 1,000′ depth (below the lake-surface in Inisfree):  ~440 PSI
  • 1,500′ depth (below the lake-surface in Inisfree):  ~670 PSI
  • 2,000′ depth (below the lake-surface in Inisfree):  ~890 PSI
  • 2,500′ depth (below the lake-surface in Inisfree):  ~1,110 PSI
  • 3,000′ depth (below the lake-surface in Inisfree):  ~1,330 PSI
  • bottom (3,500′ depth; below the lake-surface in Inisfree):  ~1,500 PSI
