It should be noted that ships at sea tend to avoid areas of bad weather. Because of this, weather information presented here is biased towards favorable weather conditions.
The marine data bases these wind rose were derived from are a compilation of reports from a wide range of sources. Observations were obtained from ship logs, weather reporting forms, publications, automated observing platforms, global telecommunications circuits, foreign meteorological services and scientific research projects. The quality of instruments ranged from those found aboard 19th century ships to sophisticated electronic equipment aboard today's research vessels. Observer qualifications varied from deck hand to trained meteorologist. Errors and discrepancies in the data are present because of the varying quality of the input sources, changes in observing practices, coding practices and data processing procedures through out the history of the data collection. Whenever possible or economically feasible, known errors or discrepancies were corrected by the National Oceanic and Atmospheric Administration (NOAA).
