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
Spring SQUID deployments across ocean basins
EM-APEX profiling floats measuring temperature, salinity, horizontal currents, and turbulence are continuing to be deployed into the global Sampling QUantitative Internal-wave Distributions (SQUID) array. This spring, 7 floats were launched from the R/V Marcus G. Langseth in the South Atlantic on GO-SHIP repeat hydrography line A13.5, and another was launched from the R/V Kilo Moana on a short cruise to the Kauai Channel—a key location of past internal wave study in the Hawaii Ocean Mixing Experiment. SQUID floats are characterizing the internal wave energy levels in a range of ocean … Read More
AGU highlighted NOPP-GIW GRL paper
We are excited to share the Research Spotlight highlighting our GRL paper, “Phase-Accurate Internal Tides in a Global Ocean Forecast Model: Potential Applications for Nadir and Wide-Swath Altimetry” has been published on Eos.org.
