In October 2024, the internal-wave resolving (IWR) array mooring team set out on another voyage to recover field instruments, including a high vertical-resolution mooring system and bottom mounted, current-and-pressure-equipped inverted echo sounders (CPIESs), as part of the NOPP-GIW program to better predict internal waves in the ocean. Manifested as density disturbances in the ocean interior, these internal waves are generated by surface wind and tidal flows interacting with bottom ridges. Their generation, propagation and dissipation have critical implications for coastal dynamics and water-mass mixing in the Earth’s climate system. The … Read More
NOPP GIW Internal Wave Resolving array mooring deployed
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
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
