The Northeast Area is just that: the small area in the Northeastern quadrant of the Weddell Sea. This diving spot drops the player character into the water facing Southwest.
This area has no description in your notebook, but when you dive here, the description on screen reads:
"Penguins and seals entertain visitors to this region with their fish-chasing antics. There are also many whales to be seen here."
The statistics for this region's attractions are three stars for fish, 2 stars for zoom-mode spots, no stars for coral, four stars for dolphins, and no stars for treasure.
