Abstract:
The data presents field sampling undertaken at Nazareth tidal flat and marsh located west of Rimouski on the southern shore of Lower St. Lawrence Estuary (Canada). Three cross shore transects (A, B, C) were established with a total of 29 stations covering high marsh, low marsh, mudflat and sandflat. The erodability of sediment was measured with a cohesive strength meter (CSM Mk IV) in terms of critical erosion threshold (n=5). Measurements for the annual changes in critical erosion threshold were conducted in three consecutive summers on transects A, B, C in 2016 (9-11 August), 2017 (23-25 August) and on transect B in 2018 (6 September).
