Operations at Station ALOHA are proceeding as planned and on schedule.
The weather today continues to be lovely and enjoyable. Both the sediment traps and gas array traveled in a hook shaped clockwise pattern (to the NE and then to the SW) over the past 24 hours. It has been a long time since we have seen the arrays drift to the south at Station ALOHA.
