1. General Description of Data to be Managed

1.1. Name of the Data, data collection Project, or data-producing Program:
Sea Levels Online: Sea Level Variations of the United States Derived from National Water Level Observation Network Stations
1.2. Summary description of the data:

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 128 stations of the National Ocean Service's (NOS) National Water Level Observation Network (NWLON) having between 30 and 146 years of data. The sea level variations determined are the linear trend, the average seasonal cycle, and the interannual variability at each station. Monthly data up to the end of 2006 were used in the calculation and all stations had data spanning a period of 30 years or more. Since the derived trends include the local vertical land motion, they are spatially variable. Calculated MSL trends range from 9.85 mm/yr for Grand Isle, LA to -16.68 mm/yr for Skagway AK, and are consistent with previous trends published by NOS. Available data from this project include time series plots 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 which was obtained after accounting for the average seasonal cycle; the seasonal cycle; the Interannual variation of mean sea level for all data to 2006; and the Interannual variation from 1980 to the present (updated monthly). 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.

5.1. Processing workflow of the data from collection or acquisition to making it publicly accessible
(describe or provide URL of description):

Process Steps:

  • The data examined in this study consist of monthly mean sea levels (MSL) for 128 NWLON stations in operation for a span of at least 30 years. Although there may be long data gaps at some of the locations, the existing data provide good estimates of linear MSL trends since the vertical datums have been maintained though 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 uniform 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.In order to investigate whether MSL trends have been changing recently, the trend for the period 1950-1999 was calculated for the sixty NWLON stations with data spanning these years. When the trend from each station's entire data set was compared to the 1950-1999 trend, at only three stations (Eastport, Portland, and Boston) was there a statistically significant difference. At these three northern U.S. Atlantic stations, the recent trends are significantly lower than each station's overall trends. At none of the stations was the 1950-1999 trend significantly higher than the station's overall trend. The differences observed between stations, during this time period, were mostly due to differences in vertical land motion.The possibility that there are other 50-year periods with MSL trends statistically different than the overall trend is examined for sixteen of the NWLON stations with the longest data sets. Six Atlantic stations (Portland, Boston, The Battery, Baltimore, Charleston, and Cedar Key) have periods centered on years between 1930-1955 with significantly higher trends and/or periods centered on years between 1965 and 1975 with significantly lower trends. Seattle has a period centered on 1925 with a significantly lower trend and a period centered on 1945 with a significantly higher trend. For San Francisco, trends for 50-year periods centered from 1890 to 1915 are significantly lower than both the overall trend and the trend since the 1906 San Francisco earthquake. For periods centered on 1895, 1900, and 1905, the trend is actually negative. This suggests that there may have been a small vertical offset and/or change in trend caused by the earthquake.
