Master track of Eugen Seibold cruise ES19C12, Caniçal - Ponta Delgada, 2019-06-18 - 2019-06-25

This dataset contains the validated master track of the S/Y Eugen Seibold during expedition ES19C12, 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.本数据集收录了ES19C12航次期间尤金·赛博尔德号科考帆船（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相关数据处理的参考基准。 为构建该主航迹，科研人员对尤金·赛博尔德号科考帆船搭载的GPS位置传感器采集的1秒分辨率原始数据进行了处理：在等间距10秒的时间区间内对纬度与经度进行平均运算。 本次主航迹的质量控制采用人工目视检查与相邻定位点间最大航速核查相结合的方式实施；若计算得到的航速超出合理上限，则移除对应数据点。
