The waves were minimal today, which made for a great day to bring out the divejet for the survey. A Signature 1000 ADCP was mounted on the divejet with the transducers facing down as drivers drove around the array on the surface of the water to cover areas that weren’t already covered by instruments. Drivers took 45-60 minute shifts on … Read More
Sunday Jun 26th: Installation of Small Scale Array Complete, and Goodbye Grad Students!
More than 20 dives and 40 chilly underwater person-hours later, installation of the small scale array was completed today! Many thanks to the awesome dive crew: Tony, Alyssa, Duncan, Loren, Annie, Kent, and Johanna, and boat crew: Kate, Kent, Rob, Kanoa, and Falk. Over the past 3 weeks we prepped the rock and installed 5 ADCPs, 10 Vectors, and 10 … Read More
Saturday Jun 25th: ADVs and the Kelp Monster
After finding that some ADCPs were getting buried in the sand yesterday, it was decided that they should be checked again by divers and moved out of the sand into a rocky area to prevent scouring and getting the transducers covered by sand. Divers went out to China Rock today to check that instruments were level and not covered by … Read More
Saturday June 25th: Hopkins Seaweed Survey by Mark Denny
One hypothesis of ROXSI is that the drag on a lush carpet of benthic seaweeds could add substantially to the dissipation of wave energy on rocky shores. To approach that question, we needed to quantify the abundance of seaweeds at our experimental sites. Fortunately, last Saturday (June 25) was a beautiful day for surveying seaweeds: minimal swell and negligible wind. … Read More
Friday Jun 24th: Nearing the finish
Friday was another classic Monterey morning and the whole team would be offshore today finishing up deployments at the China Rock array and continuing work on the small-scale array. One of the previously deployed smart moorings at China Rock was having issues so the day began with the task of recovering that mooring and replacing it with a new smart … Read More
