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.
