Job Summary: The Postdoctoral Research Associate will conduct high-resolution numerical modeling, data analysis, and model validation in collaboration with a multidisciplinary research team. The position offers opportunities for independent research, publication, and collaboration with leading ocean scientists as part of a multi-institutional National Ocean Partnership Program (NOPP; https://nopp-giw.ucsd.edu/) effort. This full-time, 12-month position is supported by a three-year Office of Naval Research (ONR) grant. In recent global ocean simulation studies (Solano et al., 2023; Buijsman et al., 2025) it has been shown that supertidal (nonlinear) internal wave energy is enhanced … Read More
New internal tide corrections dataset available!
New Dataset based on HYCOM forecast system enhances Internal Tide corrections for SWOT Cal/Val The internal-wave resolving (IWR) modeling team have released a valuable new dataset providing sea surface height (SSH) corrections for internal tides derived from the HYbrid Coordinate Ocean Model (HYCOM), specifically tailored for the Surface Water and Ocean Topography (SWOT) mission’s Calibration and Validation (Cal/Val) phase. This resource, which accounts for both phase-locked and non-phase-locked internal tide components, promises to refine the accuracy of satellite altimetry data and advance our understanding of ocean dynamics. Internal tides—subsurface waves … Read More
OSM 2026 is on the horizon!

Back to shore and that’s a wrap (for now)!
We’ve come to a close of AT50-39! It’s been a fabulously successful and productive cruise. We have: deployed the second Internal Wave Resolving Array in the Aleutians tidal beam, deployed the Longline Array in the generation region along the slope, deployed 3 EM APEX SQUID floats conducted 6 dives with the REMUS 6000, collecting valuable data about the seabed and bottom boundary layer, conducted several multibeam surveys with the shipboard EM124 to map areas not previously covered with shipboard surveys (including a survey that was critical for successful deployment of … Read More
Aleutian slope Long Line is in and all SQUIDs deployed!
With it’s light and long design using a combination of tilt current meters and temperature sensors, the UDelaware NGIW long line mooring is readied on the back deck of the R/V Atlantis (photo by Magdalena Andres) The long line moored array has been deployed off the Aleutian slope! It went really well this morning and here are a few shots of the UDel / WHOI team prepping to deploy their long line on the Atlantis. With all the moored assets deployed, and the SQUID floats deployed, we’re doing CTD, ADCP … Read More
IWR Array is in with the Long Line and SQUID floats on their way!

(photo Magdalena Andres) The IWR Array deployment is complete (with 8 CPIESs and the central full-water-column mooring in about 5300 m water depth)! It will be measuring the tidal beam that emanates from the Aleutian Islands for the next ~12 months, until we recover the array. We’re in the middle of the 5th of 6 REMUS dives and we’ve deployed two of the three SQUID floats (EM APEX). After the AUV dive, we’ll … Read More
Atlantis updates and it’s mooring deployment day off the Aleutians!
WHOI’s Jess K. readying a CPIES for deployment. (photo by Magdalena Andres) Things are going well out here. The WHOI CPIESs team (Jessica K., Will H. and Magdalena A.) and Drew C. have deployed 5 of the 9 CPIESs. CPIES deployments are little different on Atlantis than on most ships, but it works really well to throw the float over the starboard quarter and then lift the CPIES over the side with the crane (that has worked better for us than doing it midship, where the swirling flow tends … Read More
