Ground‐Truthed Fiber‐Optic Sensing Reveals Internal Tide Bores Over Madeira's Steep Slope

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We demonstrate the combined utility of distributed acoustic sensing (DAS) and repeat conductivity‐temperature‐depth (CTD) profiling for observing internal tide dynamics over a sloping seafloor. While DAS has been widely proposed as a method to infer ocean temperature variability from seafloor cables, quantitative in situ validation has been ...

Internal Wave Observations Off Saba Bank

Frontiers in Marine Science, 2019
The deep sloping sides of Saba Bank, the largest submarine atoll in the Atlantic Ocean, show quite different internal wave characteristics. To measure these characteristics, two 350 m long arrays consisting of primary a high-resolution temperature T ...

Semidiurnal Internal Tides Observed on the Eastern Flank of Hanna Shoal in the Northeastern Chukchi Sea

Journal of Geophysical Research: Oceans, 2022
AbstractThis paper investigates the role of semidiurnal tides in the Hanna Shoal region on the northeastern Chukchi Sea shelf to evaluate their impact on the regional shelf dynamics. The study is based on 2‐year long velocity time series from five oceanographic moorings. These records indicate the dominance of wind‐generated near‐inertial energy during

Fifty Years of Shore Platform Erosion Monitoring at Kaikōura Peninsula, South Island, Aotearoa‐New Zealand

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Fifty years of micro‐erosion metre monitoring at Kaikōura show that the 2016 earthquake more than doubled shore platform erosion rates, transforming intertidal shore platforms into rapidly degrading supratidal marine terraces and reorganising the process and lithological controls that govern rock coast evolution.

Effects of internal tides on GNSS-A seafloor crustal deformation observation

Progress in Earth and Planetary Science
Internal tides are crucial in ocean dynamics and are a source of error in marine acoustic measurements. In Global Navigation Satellite System-Acoustic combination technique (GNSS-A) seafloor crustal deformation observations, which contribute to ...

Characterizing the nonlinear internal wave climate in the northeastern South China Sea [PDF]

Nonlinear Processes in Geophysics, 2010
Four oceanographic moorings were deployed in the South China Sea from April 2005 to June 2006 along a transect extending from the Batanes Province, Philippines in the Luzon Strait to just north of Dong-Sha Island on the Chinese continental slope.

On the Influence of Currents and Grain Size on Wave Orbital Motion Scaling Dependence of Sand Ripple Geometry

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Using field observations from the MEGAPEX and Coastal Genesis 2.0 (CG2‐DVT2) campaigns along the Dutch coast, along with laboratory data from the DUNE3 experiment, we examine how ripple geometry responds to variations in orbital diameter, sediment grain size, and current forcing. Results show that ripple wavelength follows a weakly superlinear

Interaction Between Typhoon, Marine Heatwaves, and Internal Tides: Observational Insights From Ieodo Ocean Research Station in the Northern East China Sea

Geophysical Research Letters
Typhoons, fueled by warm sea surface waters, heighten concern as they increasingly interact with frequent Marine Heatwaves (MHWs) in a changing climate. Typhoon Hinnamnor (2022) weakened and re‐intensified as it approached the Korean Strait, interacting ...

Propagation of the Semidiurnal Internal Tide: Phase Velocity Versus Group Velocity [PDF]

Geophysical Research Letters, 2017
AbstractThe superposition of two waves of slightly different wavelengths has long been used to illustrate the distinction between phase velocity and group velocity. The first‐mode M2 and S2 internal tides exemplify such a two‐wave model in the natural ocean.

Influence of Prolonged Submergence or Exposure to Air on Photosynthesis and Carbon Dioxide Exchange in a Microtidal Spartina Alterniflora Salt Marsh

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Salt marshes are widespread along temperate coastlines globally. They provide myriad ecosystem services that support natural and human systems. Some salt marsh plants, like Spartina alterniflora, grow best in a window of elevation within the tidal range that results in a regular pattern of inundation and exposure that the plant is adapted to ...
