Field and Experimental Observations Show Elevated Shear Strength of Active Margin Sediments Requires Processes Beyond Normal Consolidation

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Near‐seafloor marine sediments on active margins have been shown to be stronger than those on passive margins. However, the reasons for this are not fully understood. To investigate the role of intrinsic properties, we performed resedimentation and oedometer tests and measured undrained shear strength, grain size, mineralogy, and plasticity on
