Oceanographic data collected during the EX1505 (October 2015 Transit: Honolulu, HI to Alameda, CA) expedition on the NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from October 5, 2015 - October 16, 2015 (NCEI Accession 0138039)

Throughout this cruise, multibeam data was collected 24 hours a day and XBT casts were conducted every 6 hours. Additionally, EK 60 (split beam) and sub-bottom profile data were collected 24 hours per day, with subbottom profile data collection at the discretion of the CO. Onboard multibeam data processing was minimal due to limited staffing. Daily or bi-daily multibeam products were produced according to established shipboard SOP and sent to shore through established shipboard SOP. Onshore mapping physical scientists monitored data quality, cruise progress, and discovery potential. Raw EK 60 and subbottom data was sent to the shoreside repository through established shipboard automated archival procedure.本次科考航次期间，我们以每日24小时的频率不间断采集多波束测深数据（multibeam data），并每6小时开展一次抛弃式温深仪（Expendable Bathythermograph, XBT）投放作业。此外，我们同样以24小时/日的频次采集EK 60（分裂波束型）声学数据与海底浅层剖面数据，其中海底浅层剖面数据的采集工作由航次指挥官（Commanding Officer, CO）酌情决定。受限于航次人员配置，船载多波束数据处理工作量极小。我们依据既定的船载标准作业程序（Standard Operating Procedure, SOP）生成每日或隔日的多波束成果数据，并通过标准化船载流程将其发送至陆上数据节点。岸基测绘物理科研人员负责监控数据质量、航次推进进度与潜在科学发现价值。原始EK 60声学数据与海底浅层剖面数据将通过既定的船载自动归档流程上传至岸侧数据存储库。
