Raw acceleration data and images are provided for 20 locations spaced at ~500 m on the mudflat ~2 m in front of eroding or expanding edges of Caerlaverock saltmarsh, Solway Firth, Scotland. Acceleration data was gathered by the Mini Buoy (B4+ design) at rates of either 1 second (monthly redeployments) or 10 seconds (quarterly redeployments) between March 2021-2022. The data has been cleaned to remove any data gathered before/after deployment. Coordinates of each location and the status of the marsh edge (eroding or expanding), and images of the marsh edge at each Mini Buoy deployment are also present. The data is being used to identify hydrological thresholds (inundation duration, current and wave orbital velocities) that determine whether saltmarshes expand or erode.

Provenance & quality
Data were obtained using Mini Buoys (acceleration data logger in a bottom-mounted float) between 01-03-2021 and 01-03-2022 at Caerlaverock saltmarsh, Solway Firth, Scotland. Caerlaverock is a dynamic saltmarsh undergoing areas of expansion and erosion - the deployment of Mini Buoys here allows identification of hydrological thresholds for expansion or erosion. B4+ Mini Buoys were deployed. Each individual logger sampled y-axis acceleration at 1Hz. Coordinates showing the location of each Mini Buoy deployment are expressed in WGS84 standard.
In total, 20 Mini Buoys were deployed - location data (as WGS84) are stored in Coordinates.csv. Acceleration data are stored in csv files and each contain acceleration measurements of an individual Mini Buoy (MB04, MB05, etc.) at a particular time period (i.e. Apr-May 2021; June-Sep 2021, etc.). There are 118 .csv Mini Buoy files in total. Data are provided as sub-minute measurements (DD/MM/YYYY HH:MM:SS) of acceleration date (Yacc) expressed as gravity-compensated acceleration values in g-force (G).
Images are provided of each of the 20 Mini Buoy sites as .JPEG.
1st processing stage only (to remove data before/after deployment). Future work will involve extracting metrics on inundation duration, current and wave orbital velocity values.

Supplemental information
This dataset is part of a wider Mini Buoy series - where acceleration and hydrodynamics data were recorded across the Indian Ganges Brahmaputra Meghna, Mekong and Red River Deltas. Mini Buoys offer a practical and open-source way to assess the hydrological dynamics (in terms of inundation, currents and waves) of mangrove forest - allowing assessment of suitability of mangrove plantation schemes. Mini Buoys cost less than $400 to assemble, and the material to build one can be purchased around the globe.
Data can also be uploaded as part of an App, where anyone can upload Mini Buoy data and find out if a mangrove site is suitable for restoration.
