New paper alert! Yadidya et al 2024
New paper led by Yadidya, the U-Michigan based NOPP-GIW IWR Modelling team postdoc! Tidal flow over topographic features on the seafloor generates vertical displacements along the interfaces of ocean layers that have different densities. These vertical displacements at tidal frequencies are known as internal tides. Internal tide displacements are largest well below the sea surface, but also display a sea surface height (SSH) signature that is large enough to be measured by satellite altimeters. Removing internal tide signals from satellite altimeter SSH allows for a more accurate accounting of non-tidal … Read More
January 2024 Annual Meeting Success!
We had a great annual NOPP meeting at the Marine Research Center of USM in Gulfport (1/24-1/25) to discuss the project results from the 6 teams involved. The meeting featured both poster and oral presentations by students, postdocs, and PIs. In addition we had invited additional speakers from outside the project to provide a broader perspective: Jacqueline McSweeney from Stony Brook University: New Observations of Internal Waves in the New York Bight Julian Simeonov from NRL: Sediment mobilization by internal waves/tides on the California shelf Ian Stokes from Scripps Insitution … Read More

New paper alert! Raja et al 2023
Spurious internal wave generation during data assimilation in eddy resolving ocean model simulations Keshav Raja, Research Faculty at FSU, and other NOPP GIW team members have a new paper in revision at Ocean Modelling! Data assimilation combines observations with ocean models to improve ocean state predictions beyond the capabilities of observations or models alone, but it can introduce problems like initialization shocks leading to spurious internal waves. These spurious waves disrupt the model energetics and must be controlled for accurate representation of high-frequency, small-scale ocean dynamics in assimilative model simulations. … 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
