This dataset includes all data which were collected as part of this study on how small-scale gradients in sediment characteristics can act as early indicators for saltmarsh cliff initiation, which typically proceeds marsh erosion and retreat. Data include those from three stages of testing: i) field measurements of sediment characteristics around saltmarsh edges ii) fast flow flume (FFF) measurements of sediment erodibility of samples surrounding saltmarsh edges and iii) a wave mesocosm experiment to identify whether sediment offsets proceed a saltmarsh cliff forming. . Overall, we provide insight into the role of small-scale gradients in sediment stability for driving the long-term dynamics of biogeomorphic saltmarshes, which can be used as early indicators to identify cliff-prone saltmarsh areas.
