# APEX float data from float 8146 (PI: Angelicque White, University of Hawaii) deployed during the Grandients 4 cruise (TN397) in Nov 2021 at ~20N/140W (float is still transmitting data) # Designed float mission: a repeated sequence of burst sampling (~6 profiles/day) of the top 200m for ~ 4-7 days, followed by daily profiles for ~10-14 days # DATA ARE PROVISIONAL AND WILL BE ALTERED AS MORE PROFILES ARE ADDED (eg. drift correction of sensors will likely be performed in the near future) # For questions about float data, please inquire Fernanda Henderikx (fhenderi@hawaii.edu) # date of
