Bacteria as Passive Passengers in the Equatorial Pacific Biological Carbon Pump

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bacteria are important agents modulating the efficiency of the ocean's biological carbon pump (BCP). The long‐standing view considers bacteria as degraders of sinking particulate organic carbon (POC), yet underappreciates their contribution to carbon export.

Airborne Photon‐Counting LiDAR for Shallow‐Water Bathymetry With Robust Noise Removal and Depth Retrieval

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Airborne photon‐counting LiDAR has emerged as a promising tool for shallow‐water bathymetry, offering high spatial resolution and penetration depth for coastal and nearshore applications. This study presents an integrated workflow for processing airborne photon‐counting LiDAR data to estimate shallow‐water bathymetry.

Observing Broadband Tsunamis in Deep Water Via Distributed Acoustic Sensing

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Tsunamis have been detected as strain variations in optical fibers of submarine cables through distributed acoustic sensing (DAS). However, the usefulness of strain variations during tsunamis for early warning remains unclear. Here, we compare fiber strains and sea‐level changes for both infragravity waves in ambient noise and tsunamis ...
