Master track of Eugen Seibold cruise ES21C16, Playa Blanca - Playa Blanca, 2021-09-24 - 2021-09-25@en

This dataset contains the validated master track of the S/Y Eugen Seibold during expedition ES21C16, 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ES21C16科考航次期间S/Y尤金·赛博尔德号（S/Y Eugen Seibold）的经校验主航迹（master track），该航迹的时间分辨率约为10秒。该主航迹可作为后续科考航次数据处理的参考基准。为生成该主航迹，科研人员对S/Y尤金·赛博尔德号搭载的GPS位置传感器采集的1秒分辨率原始数据开展了处理：在等距10秒间隔内对纬度与经度进行平均取值。科研人员通过目视检查及核查相邻点位间计算所得最大航速两种方式开展质量控制。若出现超出合理阈值的高航速，则将移除对应的数据点。
