Count Component Title Abstract
1 Sea Level Trends: Sea Level Variations of the United States Derived from National Water Level Observation Network Stations Water level records are a combination of the fluctuations of the ocean and the vertical land motion at the location of the station. Monthly mean sea level (MSL) variations were analyzed for the stations of the National Ocean Service's (NOS) National Water Level Observation Network (NWLON) having at least 30 years of data. The sea level variations determined are the relative sea level trend, the average seasonal cycle, and the interannual variability at each station. Since the derived trends include the local vertical land motion, they are spatially variable. The relative sea level trend plots include the time series for each station of the monthly MSL with the seasonal cycle removed, a 5-month average, and the linear trend with its 95% confidence interval; the average seasonal cycle; the interannual variation of MSL. The plots are updated monthly and the long-term trend is recalculated every year. The location and timing of any major earthquakes near stations in tectonically-active areas are noted since an associated vertical offset or a change in MSL trend is possible.

                    Count Component DateTime Description
                    1 The data examined in this study consist of monthly mean sea levels for CO-OPS water level stations in operation for a span of at least 30 years. Although there may be years-long data gaps at some of the locations, the existing data can provide a good estimate of the linear MSL trend since the vertical datums have been maintained through periodic leveling to stable benchmarks with respect to the adjacent landmass. The monthly means are an average of hourly water level heights for a complete month of data. The sea level variations determined in this study were the linear secular trend, the average seasonal cycle, and the residual variability at each station. Recorded water levels are a combination of changes in the sea level and the vertical land motion at the location of the gauge. Therefore, the trends derived are relative MSL trends and can be considered valid only for the region near the gauge with similar vertical land motion. Calculation of absolute MSL trends requires the accurate determination of vertical land motion at the gauges and is beyond the scope of this study.
