Slow slip along the Hikurangi margin linked to fluid-rich sediments trailing subducting seamounts
Large seamounts and basement relief cause permanent deformation when they collide with
the overriding plate at subduction zones. The resulting structural and compositional …

Trench floor depositional response to glacio-eustatic changes over the last 45 ka, northern Hikurangi subduction margin, New Zealand
Glacio-eustatic cycles lead to changes in sedimentation on all types of continental margins.
There is, however, a paucity of sedimentation rate data over eustatic sea-level cycles in …

Estimating compressional velocity and bulk density logs in marine gas hydrates using machine learning
Compressional velocity (Vp) and bulk density (ρb) logs are essential for characterizing gas
hydrates and near-seafloor sediments; however, it is sometimes difficult to acquire these …

Plate‐rate frictional behavior of sediment inputs to the Hikurangi subduction margin: How does lithology control slow slip events?
The northern Hikurangi subduction margin hosts slow slip events (SSEs), which are
exceptionally shallow (< 15 km). The sedimentary sequence on the incoming plate is …
