CCE LTER process cruise, in the California Current region, event log records including date, time, position and activity for use in post-cruise data integration based on co-sampling indexes. From 2006 to 2019 CCE LTER used a locally developed event logging system. During P2107, CCE LTER started to

The event logger program developed and maintained by the California Cooperative Oceanic Fisheries Investigations, SIO, program is used aboard CCE LTER process cruises to create indexes with temporal, spatial and activity information for post-cruise data integration. The event log is configured aboard the ship for the recording of sampling events by both ship crew personnel on the bridge, and research personnel in the lab. The event log is processed post-cruise to correct for various errors.

由斯克里普斯海洋研究所（Scripps Institution of Oceanography, SIO）运营维护的加州合作海洋渔业调查（California Cooperative Oceanic Fisheries Investigations, 简称CCE）项目，开发了事件记录器程序（event logger program）并对其进行维护。该程序被搭载于CCE长期生态研究（Long-Term Ecological Research, LTER）作业航次中，用于生成包含时间、空间与活动信息的索引文件，以支持航后数据整合工作。该事件日志系统会在船舶上完成配置，以供舰桥船员与实验室科研人员分别记录采样事件。航后将对事件日志进行处理，以修正各类错误。
