Abstract NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) has developed an innovative system design to collect water level data in remote, cold climate regions where winter sea ice precludes traditional tide station installations. In August 2008, two specially designed bottom-mounted water level gauges were deployed approximately 2 miles off the coast of Barrow, Alaska, in 100 feet of water. The systems were equipped with a high-stability pressure sensor, conductivity sensor, an acoustic modem, disposable ballast, and a pop-up buoy for recovery. Both systems were recovered one year later, in August 2009, and redeployed to collect a second year of water level, water temperature, and salinity data with recovery in August 2010. This project represents the specific development of water level measurement technology for long-term deployment in the Arctic environment and the continuous two-year water level record has supported the understanding of seasonal variability and climate change on the North Slope. The data show strong correlation with the water levels observed to the east at Prudhoe Bay including very similar response to meteorological forcing. The data obtained represent one of the most unique and valuable data sets collected by NOAA on the North Slope and the results have already contributed to an improved vertical reference system for the region.
