OPR-R320-KR-22 Cape Newenham, AK
|
Recap
- R/V Norseman II continued MBES data acquisition in H13564, H13569, and H13570, and acquired bottom samples.
- As of 6/15, R/V Norseman II transited from Platinum, AK to Homer, AK for demobilization.
-
WAM-V 22 is demobilized.
- R/V Thunder continued MBES data acquisition in H13563 and H13564. On 6/15, 6/16, and 6/17, R/V Thunder transited to Bethel to conduct a reprovision and crew change, then transited back to the survey area to continue MBES data acquisition in H13563.
- Office staff continued processing and reporting.
Looking Forward
- R/V Norseman II will arrive in Homer, AK on 6/19 and will be demobilized.
-
WAM-V 22 has been demobilized.
- R/V Thunder will continue MBES data acquisition in H13563 and H13564. MBES data acquisition includes mainscheme, crosslines, and fill.
- On 6/23, R/V Thunder will transit to Bethel for a crew change and reprovision, and will transit back to survey area on 6/24 to continue MBES data acquisition and bottom sampling in H13563 and H13566.
- Office staff will continue processing and reporting.

OPR-Y396-KR-22 Western Lake Michigan, WI
|
Recap
- R/V Benthos collected mainscheme multibeam survey data in H13635, H13636, and H13637.
- R/V Benthos collected crosslines in H13635 and fill lines in H13636, along with backscatter and performance calibrations.
- The on-site field team moved operations from Port Washington to Sheboygan and the R/V Benthos is now working out of the Sheboygan marina.
- The R/V Substantial arrived on-site in Port Washington and began calibrations.
- The MVP freefall fish was repaired and a new cable was spooled. After verifying and testing all sensors, the MVP is now operational.
Looking Forward
- R/V Benthos will continue the inshore MBES survey in H13637, working out of the Sheboygan marina.
- The R/V Substantial will complete calibrations and will begin MBES survey offshore in H13635 and H13641, with dock-side rotations occurring at the Port Washington Marina.

OPR-R302-KR-22 Nunivak, AK |
Recap
-
Qualifier 105 (Q105) and C-Worker 5 ASV (ASV) completed transit from Bethel and began survey in the project transit area (F00847) on 6/15. Vessels continued north in transit area, following its northern border, into 6/16. The 10 m contour was encountered on the north end of the transit area and largely developed; a small amount of additional development of the 10 m contour there is still necessary and planned for the next transit through the area.
- On 6/16, the vessels surveyed through H13591, H13592, and H13593 while in transit to northern Nunivak Island.
- Survey began in the higher priority areas H13589 and H13590 on 6/17. The recon into the Mekoryuk area, including collecting depths to 1 m MLLW with the ASV, was started on 6/17 and continued into 6/18, working around high tide. The Mekoryuk recon was underway at end of day 6/18.
- There are no recommendations at this time for line spacing changes the majority of the sheets. However, it is recommended that the F00847 transit area receive 800 m line spacing instead of the specified 480 m spacing. The transit area is in a region of generally very gentle slope and relatively featureless bottom, and more of this uncharted area could be surveyed during the limited number of planned transits given wider line spacing.
Looking Forward
- Complete Mekoryuk recon survey to 1 m. This was in progress at end of day 6/18 and will complete 6/19.
- Deploy GNSS buoys, weather permitting. Some southerly weather may prevent deployment for the first part of the week, but late week looks favorable.
- Survey where weather allows.
