End of Leg 7

Leg 7 of VISIONS ’14 was only a single dive, to deploy a cabled surface-piercing profiler at the Oregon Shelf site. This successful dive concludes the entire summer of deployments on a high note.

Cabled surface piercing profiler at OR Shelf

The cabled coastal surface-piercing profiler (cCSPP) was delivered to the seafloor by ROPOS and placed roughly 12 meters due East of the medium-powered junction box MJ01C at the Oregon Shelf site, in 79 meters of water. The cylindrical sensor pod of the cCSPP (left side of image) will float freely in the water column after being released from the deployment cradle on the profiler base. Once powered up, the sensor pod will move up and down in the water column at least 4 times per day, taking samples continuously using the onboard CTD, oxygen, fluorometer, nitrate, AC-S, PAR sensor, spectral irradiance, and 3D water velocity sensors.

Shallow Waters

The end of Leg 3 is approaching rapidly, and we successfully met every goal for this leg of the VISIONS14 expedition, including some originally scheduled for Leg 2. We’ll be back in Newport by morning. On to Leg 4!

Standing on Two Legs

We have another first to report: the first deployment of a two-legged shallow profiler mooring at the Endurance Oregon Offshore site! The mooring operations were smooth, safe, and ultimately a complete success, thanks to a remarkable run of calm weather.

200m Shallow Profiler Platform in Water

Deployment of the 200m platform of the Endurance Oregon Offshore two-legged mooring, which will eventually host a winched shallow profiler and bioacoustic sonar instruments. Two mooring lines with seafloor anchors are attached to the sides of the platform (rather than the usual single mooring line) to add stability to the platform so it can act as the profiler base.

Lowering Slope Base Seismometer into Caisson

ROPOS lowering the Slope Base seismometer into the previously excavated caisson. After deployment, the caisson was filled with glass beads to couple the seismometer to the seafloor. The attached hydrophone tripod is being held in the starboard arm of ROPOS, and was deployed alongside.
