During the week of March 13, 2017 the Caribbean office of the USGS Caribbean-Florida Water Science Center is transitioning to a new data management software package. While you may not notice this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible.


The statistics generated from this site are based on approved daily-mean data and may not match those published by the USGS in official publications. The user is responsible for assessment and use of statistics from this site. For more details on why the statistics may not match, click here.
