Acceleration data-set

This dataset contains high-resolution acceleration measurements collected during a field campaign conducted from June 7 to June 29, 2024, in the Bahía Blanca Estuary, Buenos Aires Province, Argentina. Data were acquired using a custom-built sensing system based on an MPU6050 accelerometer, controlled by an ATMEGA328P-PU microcontroller and stored on a microSD card. The instrument was housed in an IP67-rated waterproof enclosure and mounted on a beacon buoy deployed in the estuarine environment. Due to the installation geometry, the sensor box was positioned with a 7° angular offset relative to the buoy symmetry axis. Measurements were recorded at 100 ms intervals with a full-scale range of ±4 g, yielding more than 18 million samples for each acceleration component. Each file includes record number, sampling interval, three-axis acceleration, temperature, and battery voltage, providing a robust dataset for analyzing buoy dynamic response under estuarine forcing conditions.

本数据集包含2024年6月7日至6月29日在阿根廷布宜诺斯艾利斯省布兰卡港河口（Bahía Blanca Estuary）开展的野外试验期间采集的高分辨率加速度测量数据。数据采用基于MPU6050加速度计的定制传感系统获取，该系统由ATMEGA328P-PU微控制器控制，并将采集数据存储于microSD卡中。该仪器被封装于IP67级防水外壳内，安装在部署于该河口环境的航标浮标之上。受安装几何结构限制，传感器盒与浮标对称轴存在7°的角度偏移。测量以100毫秒的间隔进行记录，满量程范围为±4g，每个加速度分量可获得超过1800万个采样样本。每份文件均包含记录编号、采样间隔、三轴加速度、温度以及电池电压信息，可为分析河口强迫条件下浮标的动态响应提供稳健的数据集。
