The NOPP/SWOT container on the truck and headed to Alameda to meet the R/V Sally Ride! Preparations are underway for the next cruise leg of the NOPP IWR team mooring deployments (and recoveries). A total of 11 SWOT cal/val moorings and 3 PIES were deployed last February along the track of the SWOT satellite mission off of California. These moorings are one component of the fast repeat cal/val phase of the NASA-led SWOT mission. Four of these moorings, deployed and designed by the SIO teams, were full depth ocean moorings … 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
At sea with Jess and her cluster of CPIES
Playing chicken with the string of late-winter Pacific storms and racing the clock to deploy a ship-load of scientific gear within the SWOT Cal/Val site west of California, the crew and scientists on the MV Bold Horizon have had an intense cruise. Among them is Jessica Kozik – not only is Jess the only cruise participant from Woods Hole Oceanographic Institution (WHOI), but she also happens to be the only woman aboard. And she’s working with an instrument that is pretty new to her. Jess is here to deploy 3 … Read More
Detangling the complicated web of internal waves
Long term ocean observations can help us detangle the intricate web of internal wave across the globe Global ocean maps illustrate the low-mode internal wave field at the M2 tidal frequency (color-scale image) in relation to historical ocean repeat data collections: the WOCE/GO-SHIP transects (top center), the Scripps high-density XBT archive (bottom left), and the AOML high-density XBT archive (bottom right). The tidal internal waves, which are hypothesized to be a significant source of energy for the broadband internal wave field, are heterogenously distributed throughout the ocean basins. Representation of … 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
November 2022 Kickoff Meeting
We are thrilled to have participated in the 2-day Kickoff meeting Nov 3 & 4, 2023 for the NOPP-Global Internal Waves. Representatives from all 6 groups were in attendance at Scripps Institution of Oceanography for the meeting. The Kickoff included breakout groups focussing on zeroing in on the various tasks that we are going to accomplish during this NOPP. We were lucky to include some valuable additional speakers to give us more information about: SMODE (Tom Farrar, WHOI), SWOT cal/val (Jinbo Wang, JPL), NSF-funded BLT (Bethan Wynne-Cattanach, SIO), ONR-funded TFO … Read More
