-
R/V 4‐Points was on standby on 28MAY2023 and 29MAY2023. R/V 4‐Points was mobilized with a SSS following offsite vessel repairs and headed back to site on 30MAY2023. The vessel was partially down for weather on 31MAY2023, 01JUN2023, and 03JUN2023. The vessel conducted an on‐site SSS calibration on 01JUN2023. R/V 4‐Points collected SBES in H13764 and SSS/SBES and SBES in H13763.
- Data processing of SSS, MBES, and SBES has continued through the reporting period. The office continues to ingest survey data and focus on QC review, documentation and fill/recovery plans.
Looking Forward
-
R/V Benthos will collect SSS/SBES in H13764.
-
R/V Chinook will collect SSS/SBES in H13764.
-
R/V 4-Points will collect SSS/SBES in H13761 and H13763.
- The office will continue ingestion and processing of SSS, MBES, and SBES data. This week's sheet‐wide reviews will focus on SSS/MBES for H13755, H13758, and H13760 and continuing to refine fill and investigation plans. SSS/SBES reviews will continue
to develop fill and recovery plans.

OPR-340-KR-23 Bristol Bay, Alaska |
Recap
- Ended mobilization (and transit) this week and began operations. Focused on sheets in the NW part of the survey area, largely due to weather, with fair amount of weather downtime experienced this week.
- The Arctic Seal arrived in Dillingham near end of day 31MAY2023. It took fuel, departing personnel left Dillingham, and incoming (first rotation) personnel met the vessel.
- The Arctic Seal departed Dillingham for the survey area early on 01JUN2023. Initial transit survey didn’t occur due to weather. ASV was not deployed until late on 02JUN2023 due to weather.
- Survey this week focused initially on H13721. Moved west of the Nushagak Peninsula on 03JUN2023 to focus on areas that would have some protection from approaching southeasterly weather. Surveyed through H13716, H13722, H13717, and then focused on survey in H13718.
- Surveying in H13718 at end of 03JUN2023.
Looking Forward
- Expect to be confined to survey areas west of the Nushagak Peninsula for at least the first part of next week due to continued bad weather with easterly to southeasterly winds. Therefore most progress this week will likely be in H13717 and/or H13718.
- Will work towards H13715 and H13714 when conditions allow.
