I read "No Time on Our Side" by Roger Chapman a few months ago on the recommendation of HN commentor /u/z991 [1]. It recounts the 1973 rescue of a damaged submersible on the ocean floor from the perspective of the crew trapped inside [2]. Mainly their struggle with limited oxygen and rising CO2 levels. A fairly brief but gripping read which I also recommend. Of note, I recall even though the sub in question had a working acoustic phone and beacon, the rescue vessels really struggled to pinpoint its precise location and maintain communications. The ocean is a big place!
