Development and calibration data of the B4+ Mini Buoy design

Nine B4+ Mini Buoys, each sampling acceleration values along the y-axis at 1 Hz, were deployed adjacent to a water level (pressure) logger (In-Situ Rugged TROLL 100) on the tidal flat in front of Caerlaverock saltmarsh, Solway Firth, Scotland (54°58'05"N, 3°31'58"W) between the 15th and 24th of September 2020. Prior to deployment and after retrieving them, the loggers were inserted into a bucket of water for 1 minute to determine logger position in the tube. Each logger was fitted with different weights of ballast and different tether lengths. The pressure logger was set to sample at 1-minute intervals. Unfortunately, two loggers were lost during the deployment. Data to build a calibration between wave orbital velocity and acceleration was gathered at Caerlaverock, Scotland (54°58′05′′ N, 3°31′58′′ W) and Black Scar, Wales (51°45′54′′ N, 4°26′12′′ W). Data to build a calibration between hydrodynamics (inundation duration, current velocity, and wave orbital velocity) and acceleration was gathered at Percut Sei Tuan, Indonesia (3°43′22′′ N, 98°46′15′′ E), Caerlaverock, Scotland (54°58′05′′ N, 3°31′58′′ W), Black Scar, Wales (51°45′54′′ N, 4°26′12′′ W), and Skinflats, Scotland (56°03′22′′ N, 3°43′60′′ W) for three designs: the 'B4', 'B4+', and 'Pendant'.
