abstract: Coastal trapped waves (CTW) were investigated in the Black Sea during 2012–2016 using observations from the sea level stations at five locations along the southern coast of the Black Sea together with the sea surface height model from Copernicus Marine Service. Spectral and wavelet analysis of sea level data shows that CTWs exist in the Black Sea with a period of 12–13 days and 15 days duration. These waves propagate from west to east with a speed of 2.3–2.6 m s−1 and cause 10–20 cm variability
