Modelling swell propagation across the Pacific

Frontiers in Marine Science, 2023
Ocean wave swell generated in the vicinity of Campbell Island in the Southern Ocean is tracked along Great Circle paths across the Pacific Ocean. Data from a wave buoy at Campbell Island provides data on the directional spectrum in the generation region.

Geometry of Breaking Waves Under Natural Sea Conditions

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Wave breaking geometry is critical for understanding air‐sea interactions, yet its characterization in the field remains limited. This study analyzes the geometry of 16,369 active breaking waves, measured via stereo imagery in the Black Sea under diverse conditions.

Buoy Observations of Ocean Swell Propagation Across the Pacific Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract A network of more than 300 drifting wave buoys is used to study the propagation of ocean swell across the Pacific Ocean. Swell events are identified at buoys in the Equatorial region and then tracked along Great Circle propagation paths both forward and backward in time.

Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale eddy currents influence ocean surface waves, but their imprints on wave height remain poorly described by observations. Here, we examine significant wave height (SWH) variations associated with more than 42,000 mesoscale eddies in the Southern Ocean using along‐track Jason‐3 altimeter measurements.
