Coastal sea level rise around the China seas
We analyze the sea level rise along the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea (the “China Seas”) coastline using 25 tide gauge records beginning with Macau in 1925, but with most starting during the 1950s and 60s. The main problem in estimating sea level rise for the...

We analyze the sea level rise along the Bohai Sea, the Yellow Sea, the East China Sea, and the South China Sea (the “China Seas”) coastline using 25 tide gauge records beginning with Macau in 1925, but with most starting during the 1950s and 60s. The main problem in estimating sea level rise for the period is the lack of vertical land movement (VLM) data for the tide gauge stations. We estimated VLM using satellite altimetry covering the 18 stations with records spanning 1993–2016. The results show that many tide gauge stations, typically in cities, have undergone significant subsidence due to groundwater extraction. After removing the VLM from tide gauge records, the 1993–2016 sea level rise rate is 3.2 ± 1.1 mm/yr, and 2.9 ± 0.8 mm/yr over the longer 1980–2016 period. We estimate the steric sea level contribution to be up to 0.9 ± 0.3 mm/yr, and contributions from ice mass loss from glaciers and ice sheets of up to 1.1 ± 0.1 mm/yr over the last 60 years.
