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. Grain size distribution and organic matter content (loss on ignition) of surface scrape sediments were analyzed in summer 2016 and summer 2018.
Mean grain size and Sorting were calculated by Geometric method of moments. Adapted from BLOTT and PYE (2001)
