Tide Gauge Readings. The tide gauge API can return a variety of current and historical level data for monitoring Co-located instruments MCDTG. There is also significant clustering of gauges around heavily populated areas – particularly in the Northern Hemisphere (Figure 1, bottom). 107, 3026, (2002). Res. Res. Tide gauges measure relative sea level, which is the height of the water relative to the height of the land. Calculating global mean sea level (GMSL) from historical tide gauge observations is a challenging problem. The sea level data available on SONEL are: daily mean sea levels obtained from different tidal filters (e.g., Doodson, Demerliac); One of the most important sources of VLM is glacial isostatic adjustment (GIA), which is the ongoing slow rebound of the Earth’s crust after removing the weight of ancient ice that existed during the last glacial maximum [e.g. Please see TideM8. Douglas, B. C. Global sea level rise, J. Geophys. Church, J.A., White, N.J. A 20th century acceleration in global sea level rise, Geophys. These measurements provide definitive estimates of global mean sea level rise during recent decades (~3.2 mm/year from 1993 to present) with much less uncertainty than the global rate derived from tide gauges. If not handled properly, the non-uniform spatial and temporal sampling can lead to aliasing of the regional and local variability into estimates of GMSL [e.g. Two levels of quality control are provided by the UHSLC. The well prevents turbulent motion of the ocean surface from disturbing the float. Tide gauges and satellite altimetry are complimentary datasets, and both are necessary to observe the complete spectrum of processes that lead to sea level variability. Historical tide gauge data allow scientists to estimate global sea level rise since the industrial revolution, which is a powerful indicator of both the trajectory and impact of anthropogenic climate change [e.g. The HD3011 transmitter measures tide changes using a precise pressure sensor, housed in a titanium/delrin case. The current rate of VLM measured by a GPS may not be the rate of land motion over the entire tide gauge record. Second, the configuration of the global network varies substantially in both space and time (Figure 1). There are a few long records that provide mostly continuous time series since the early 19th century, but the majority of tide gauge records are much shorter. Res. Acoustic and radar gauges measure the travel time or phase change of acoustic and radar pulses sent from the sensor and reflected vertically from the sea surface. Browse data from the UK National Tide Gauge Network, owned and operated by the Environment Agency, on behalf of the UK Coastal Flood Forecasting service (a partnership between the Environment Agency, Natural Resources Wales, the Scottish Environment Protection Agency and Northern Ireland Department for Infrastructure - Rivers). This isostatic process is called the inverted barometer effect, and it can account for more than 50% of the variability in monthly mean sea level in some places. Peltier, et al., 2015]. Tide gauge records updated in the 90 days prior to 11 Jan 2021. Reviews of Geophysics, 36(4),603-689, (1998). Oceanic Technol., 23, 619–629. Bibliography MCDTG If you have a relevant reference to suggest, please send-us an e-mail : sonel@sonel.org. Correcting tide gauge data for inverted barometer is straightforward, as a 1mb increase in atmospheric pressure at sea level (SLP) corresponds to approximately 1mm of sea level fall [Ponte, 2006].
