Hiya!
We are one week in on the Ocean Observatories Initiative (OOI) Endurance Array cruise on the Sally Ride. If you have not looked up OOI yet, then let me encourage you to do so by giving you some handy links. The Endurance Array is just 1 of 6 uncabled arrays spanning the Pacific and Atlantic ocean basins and provide a wealth of data on climate variability, ocean circulation, ecosystem impacts from climate change, sub-seafloor and ocean-atmosphere interactions, plate dynamics and more! The great thing is that there is a lot of outreach to the science community and public alike, and all of the observation data is available 24/7 through the OOI data portal.
Thankfully, while we were out at sea, NSF awarded $220 million to Woods Hole, University of Washington, and Oregon State University (the team I am with) to continue to operate and maintain the OOI system for the next 5 years. Woo hoo!
This past Tuesday saw us off the coast of Washington deploying and recovering shelf and offshore moorings. The offshore moorings are over 500 meters in length, so we can only average 2 per day with these. At each site, we also do a CTD cast to collect water samples at the depths of the sensor packages as well as a good water column plot. This helps the OOI team to calibrate their various instruments as a reference.
This pattern repeated through Friday, at which point we transited down to Newport, Oregon and docked on the OSU pier in order to offload the recovered moorings and pick up more to deploy. Needless to say, there is an incredible amount of dynamic shuffling on the back deck to make way for hundreds of meters of line, EM cables, and stretch hoses not to mention massive flotation devices, anchors, vertical profilers, and sensor frames/anchors that weigh upwards of 11,000 pounds.
We always meet as a team before each deployment or recovery to assign positions and talk through the progressions of where things need to be and what block we will be pulling through to which winch and how many tag lines are needed to stabilize the various components. Communication and situational awareness are key! The rest of this week will see us finishing up the Washington inshore and offshore moorings and then we will be back in Newport one more time to do another offload and onload of gear. In total, it’s 3 legs of deployment/recoveries in just 16 days. I am confident that we can do it. 🙂
More soon!
