Sub Down

Plot hole: Rick goes into the water. This is arctic seawater, ice is above them. Rick has no protective clothing. Yet he swims around for several minutes and emerges in good condition and his clothes dry very rapidly. (01:10:00)

Continuity mistake: As we see the sub going down, the tech says "descending at 5 ft per second", and another one says "no forward motion". Cut to the sub going forward and down at considerably more than 5 ft per sec and apparently making a rumbling noise while doing it . (00:32:00)
