This document reports the results of the satellite monitored tagging experiments on North Pacific sei whales conducted during the 2017 NEWREP-NP survey. A total of 44 tagging experiments were conducted using SPOT6 type tags with LKArts system for attachments from Yushin-Maru-type sighting/sampling vessels. A total of 15 tags were deployed on sei whales, of these eight tags transmitted the locations and movement of the whales. Two sei whales were tracked for more than 35 days, and these two whales showed a longitudinal movement. In general the tagging experiment of penetrate-type tags from sighting/sampling vessels seems to be practical. However some technical improvements are identified, which could increase the tracking period.
