According to Wallin's report, UMEX (Underwater Exploration Team) found and identified Sch-317 yesterday, 2 May 2018.
This Soviet submarine lies at 78 meters / 255 ft between Gogland (Suursaari) and Tuiters (Tytärsaari) in the east part of the Gulf of Finland in Russian waters.
Sch-317 was sunk in 1942 by a German mine after surviving several attacks by allies that included bombing the Swedish coast.
The submarine's final resting place is near her home port.

When air-breathing mammals dive, their lungs compress. The ultra-deep-diving feats of some marine mammals go beyond our current understanding of respiratory physiology and lung mechanics. But historically, researchers assumed the chest structure of marine mammals meant their lungs compressed automatically at great depths, an adaptation that prevented them from taking up excess nitrogen and getting the bends.
