These cloud formations affect our work on the Half Moon in several ways. First, they can serve as an indicator of incoming weather fronts, such as the storms that have just recently been pummeling the northeast Atlantic coast. Of more immediate import for our sailors, however, overcast skies can make celestial navigation nearly impossible. Solid cloud cover on Day Three prevented the Celestial Navigation team from collecting more than a handful of data points. Fortunately, the next day saw the clouds breaking up (as seen here), allowing the research team to conduct their work.
