One of the big goals of the 2023 NOPP GIW field work was recovering and re-deploying the IWR mooring after a 200-day deployment as part of the SWOT Oceanographic Mission Cal/Val. anchordown We developed the Scripps Hybrid Real-Time Mooring (HRTM) system for SWOT Cal/Val. The system combines a sub-surface taut mooring (600 m – 4500 m) with a ocean-wave-powered Wirewalker profiler (0-500m) and a surface buoy. Data from the moored instruments are telemetered to shore in real-time. The HRTM provides continuous vertical and time mapping of the upper 500m, and … Read More
IWR Team out on the R/V Sally Ride
We are just shy of one week at sea aboard the R/V Sally Ride and with a combination of groups from SIO (MOD and Send labs) and the WHOI (CPIES Team led by me, Magadalena Andres). We are all working hard, side by side, as there is a lot happening on this cruise! This is my first cruise that includes both CPIES recoveries and CPIES deployments…usually it’s one or the other and I put myself in the mindset for that type of cruise. And unusually a cruise is related to … Read More
100 days of SWOT / NOPP data!
Profiling performance for the NOPP / SWOT calval moorings has been ongoing and excellent at all moorings for 100 days! A total of ~18,000 round trips from the Wirewalkers have been collected from the 4 moorings. This equates to a 500 m upcast profile every 35 min at each mooring on average. There is a great deal of variability between the four moorings (each separated by ~30 km), even in the long-wavelength internal tide. Here is the Wirewalker profiler data from one of the moorings. It shows the awesome temporal … Read More
SWOT / NOPP moorings are in the water
SIO SWOT / NOPP moorings S1-S4 are in the water, telemetering, and functioning as designed! The weather held off this morning, allowing us to get a relatively early and efficient start. Although the weather deteriorated to some extent over the course of the day, we were able to safely deploy the final mooring less than 100 yards from the target. The SIO SWOT NOPP real-time data can be found here: https://mooring.ucsd.edu/swot2/ The Wirewalker profiler performance has been excellent at all moorings since deployment, averaging 500 m round trips every 30 … Read More
