This dataset contains acceleration data measured from low-cost and open-source bottom-mounted floats called 'Mini Buoys', to identify hydrological tipping points between expanding and eroding mangrove edges in the Mekong Delta, Vietnam, from 25-06-2022 to 31-08-2022.
Acceleration data are available at three locations in the Mekong Delta: Ca Mau, Kien Giang and Soc Trang. Ca Mau contains acceleration data from 7 Mini Buoys; Kien Giang contains acceleration data from 5 Mini Buoys; Soc Trang contains acceleration data from 7 Mini Buoys. Each Mini Buoy's (for the different sites) acceleration data are stored in .csv files in three parent folders. Each .csv file contains equipment metadata and raw acceleration data at sub-minute intervals (in the format DD/MM/YYYY HH:MM:SS). Acceleration data are measured as gravity-compensated acceleration values in g-force (G).

Provenance & quality
Data to assess the hydrological tipping point between expanding and eroding mangrove edges was gathered at Soc Trang (09°25′11″N, 106°10′48″E), Ca Mau (08°38′00″N, 104°42′43″E), and Kien Giang (09°50′01″N, 104°53′25″E) sites along the Mekong Delta, Vietnam. B4+ Mini Buoys were deployed along seaward mangrove edges where there was a transition from expansion to erosion. Each logger sampled y-axis acceleration at 1 Hz. Coordinates showing the location of each Mini Buoy deployment are expressed in WGS84 standard. Unfortunately, some Mini Buoys were lost during deployment. No processing was done to the acceleration data.

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
