When Mulder makes his George Burns remark, he hands Scully a sample of urine, presumably from him. There appears to be only a few milliliters in the sample container, yet a moment later when Scully goes to her lab table, there is suddenly a lot more in the container.
When Scully made "water" for her and Mulder she used the water from a snow globe. However, snow globes contain anti-freeze which would have been toxic to them both.
When Dr. Laskos is seen in the Naval hospital, she has a medical corps pin on each collar. She should have that pin on one collar and a rank insignia on the other.
The title "Død Kalm" is probably meant to resemble Norwegian for "Dead Calm" (referring to the movie Dead Calm (1989)) but it's gibberish. While the word "død" actually means dead, "kalm" is not a Norwegian word. The literal translation would be "Dødelig ro" (a deadly calm), whereas the proper translation (a quiet sea without waves) would be "Vindstille" or "Blikkstille". And in any case for a Norwegian title only the first letter is capitalized (Død kalm).
Mulder mentioned that a fleet of Soviet mine sweepers vanished on their way to Havana during the height of the Cuban Missile Crisis in 1963. The Cuban Missile Crisis lasted from October 16 to October 28, 1962.
U.S. Navy ships do not use the twin-3" deck guns (visible when Mulder and Scully first board). But they are the armament for the HMCS Mackenzie (where this was filmed).
Scully mentions one of the ingredients in the jar of liquid is some juice from lemons. Since everything on the ship ages rapidly, wouldn't the lemons age as well, rendering them rotten or dried up and of no use?
Explanation: The sea water is causing the ship itself to age, but the lemons haven't been exposed to it. So this is absolutely reasonable.

Most of the Norwegian spoken in this episode is flawed, and apparently Danish language coaches were used. Two examples make this clear: the first is the word "bliver" ("becomes/stays/remains") instead of the Norwegian "blir". The second is when Vladimir Kulich is supposedly saying 'Go to Hell' in Norwegian, where he is actually using the Danish phrase, which in this case is structurally very different from the Norwegian.
When Scully finds the toilet being back flushed, she is seen following the yellow pipe. When the light reflects off her face, it is clear that Gillian Anderson isn't wearing her aged make up.
When the medical examiner at Bethesda Naval Medical Center removes the sheet off of the corpse of the first thug, it briefly reveals that he is still wearing boxer shorts.
The Philadelphia Experiment, referenced by Mulder as having used alien technology recovered from the UFO crash in Roswell, New Mexico, occurred in 1943. The Roswell incident didn't occur until four years later in 1947.
The USS Ardent is said to be a destroyer escort commissioned in 1991. However, destroyer escorts are very old and outdated ships from World War II, with the last U.S. ones being commissioned in the late 1960s and early 1970s.
Immediately after Dr. Lasko tells Scully her clearance code is invalid, the camera switches to Scully, showing Dr. Lasko from behind. Dr. Lasko's jaw is seen moving when she isn't speaking. Then when she asks "Who are you?" her jaw moves out of sync with what she's saying.
When Mulder lists the ships that had gone missing, he says a Royal Navy Battleship left Leeds. Leeds is a landlocked city in Yorkshire.
During two outside shots of the ship in the fog, trees can be seen behind the ship's bow.
Although free radicals are believed to be involved in the accumulation of cell damage and aging, they don't always contain "an extra electron" as Scully says. To be precise, a free radical would have an unpaired or lone electron, and thus be highly reactive. A molecule with an extra electron is called an anion, and is not necessarily reactive.
