However, the ships and clandestine stations were easily captured by the Allies during the early part of the war. Data from aircraft was incomplete as they were limited in range and susceptible to Allied attack. Regular weather reporting by U-boats put them at risk as it broke

Within an hour of dropping anchor, a scouting party had located a suitable site and soon after, Dr. Sommermeyer, his assistant, and ten sailors disembarked to install the station. Armed lookouts were posted on nearby high ground and other crew members set to repair the submarine's storm damage.
For concealment, the station was camouflaged. Empty American cigarette packets were left around the site to deceive any Allied personnel that chanced upon it. One canister was marked and misspelled "Canadian Meteor Service,"
in order to simulate "Canadian Weather Service," as a German attempt to avoid suspicion if discovered. No such agency existed in Canada.
