Compass Calibration
Jennifer Batryn, Nikki Arm, Irene Duran, and Ellen Roosen perform a compass spin of an Acoustic Doppler Current Profiler (ADCP) to be deployed on Pioneer MAB. It is important to do the compass calibration prior to deployment to correct for the introduction of magnetic materials during setup.
Read MoreHeavy Winch Test
In preparation for the Endurance 20 expedition, the heavy winch to be used in recovery and deployment operations on the R/V Sikuliaq, is lifted in the yard at the Ocean Observing Center in Corvallis. The heavy winch will be loaded on a tractor trailer for transport to the newly renovated Oregon State University Pier in…
Read MorePre-Deployment Testing
Pre-deployment testing of the Imaging Flow CytoBot (IFCB) to be deployed on the Central surface mooring of the Pioneer MAB Array. OOI team members Nikki Arm (left), Sheri White (center) and Sawyer Newman (right) lower the IFCB into the test well at the WHOI dock.
Read MoreSeabed Survey
The OOI-CGSN team surveyed the seabed to better understand the layout of the proposed moorings sites. The RV Neil Armstrong operated a hull-mounted acoustic equipment to collect bathymetry (depth contours), backscatter imagery (seabed characterization), and subbottom data (seabed profile and geophysical layering). Chris Basque, Irene Duran, and John Lund also piloted the ROV over the…
Read MoreBig Eyes Along the Mid-Atlantic Coast
Large binoculars called “big eyes” are used to help marine mammal observers detect and identify distant sightings. Personnel from the NOAA National Marine Fisheries Service were graciously included in the OOI Pioneer Array cruise as part of an exploratory survey targeting North Atlantic right whales and recording all other marine mammals encountered. The population is painfully small,…
Read MoreSafe and Sound
Here the test Coastal Surface Mooring is safely on deck after ~8 months operating at the proposed Pioneer Mid-Atlantic Bight location. The mooring was deployed in a water depth of 30m and survived storms with max wave heights of 7.5-10m, and continued to send data to shore!
Read MoreSurface Mooring Recovery
It may seem calm at the surface, but there’s a lot of action below…The OOI-CGSN team used the Remotely Operated Vehicle (ROV) to inspect the Coastal Surface Mooring and the Multifunction Node (MFN) prior to recovery. Chris Basque and John Lund then piloted the ROV over to the MFN and attached a hook and recovery…
Read MoreSunrise at Sea
Chris Basque, Woods Hole Oceanographic Institution deck lead, takes advantage of the calm seas and bright sunrise to survey the work area and plan the recovery of the test Coastal Surface Mooring located at the proposed Pioneer MAB Array site.
Read MoreAs Seen from Below
Everything looks good! The Remotely Operated Vehicle was deployed by the OOI-CGSN team to inspect the underwater components of the Shallow Water Mooring after deployment. The ROV captured images of the Multifunction Node sitting on the seabed (1), the mechanical bend restrictors on the riser (2), and an image of the Prawler profiling vehicle moving…
