Master track of Eugen Seibold cruise ES23C01, St. George's - Oranjestad, 2023-02-01 - 2023-02-06@en

This dataset contains the validated master track of the S/Y Eugen Seibold during expedition ES23C01, with a time resolution of about 10 seconds. This master track can be used as reference for further expedition data. For creating the master track, the 1-second resolution raw data acquired by the GPS position sensor on board S/Y Eugen Seibold were processed, averaging latitude and longitude within equidistant 10-second intervals. Quality control was performed visually and by checking the maximum speed calculated between neighbouring positions. In case of unrealistically high speeds, data points have been removed.本数据集包含航次ES23C01期间帆船游艇欧根·扎博尔德号（S/Y Eugen Seibold）的经验证主航迹，其时间分辨率约为10秒。该主航迹可作为后续航次数据处理的参考基准。为构建该主航迹，研究人员对该船搭载的GPS位置传感器采集的1秒分辨率原始数据进行处理：在等距10秒时间间隔内对纬度与经度数据取平均值。本次处理采用两类质量控制手段：一是目视核查，二是校验相邻定位点间计算得到的最大航速；若航速超出合理范围，则将对应数据点予以剔除。
