There are naturally occurring fluctuations in tidal range from one decade to the next. These fluctuations can paradoxically both reduce and exacerbate the impacts of sea level rise.  This research seeks to understand and communicate tidal phenomena. Through the installation of tide gauges in harbors, they will be able to capture the water movement from the tides rather than wave action.  The data will be used to validate ocean models, detect errors, and identify drifts in satellite altimetry.  The team will monitor the gauges’ vertical stability every year so that sea level rise can be captured.
