Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Boundary Control Behaviors of Multiple Low-Cost AUVs Using Acoustic Communication

IEEE Access
This study presents acoustic-based methods for the formation control of multiple autonomous underwater vehicles (AUVs). This study proposes two different models for implementing boundary and path control on low-cost AUVs using acoustic communication and ...

Virtual Elastic Tether: A New Approach for Multi‐Agent Navigation in Confined Aquatic Environments

Journal of Field Robotics, Volume 43, Issue 5, Page 3332-3350, August 2026.
ABSTRACT Underwater navigation is a challenging area in the field of mobile robotics due to inherent constraints in self‐localization and communication in underwater environments. Some of these challenges can be mitigated by using collaborative multi‐agent teams.

A Low-cost Electromagnetic Docking Guidance System for Micro Autonomous Underwater Vehicles

Sensors, 2019
As important observational platforms for the Smart Ocean concept, autonomous underwater vehicles (AUVs) that perform long-term observation in fleets are beneficial because they provide large-scale sampling data with a sufficient spatiotemporal resolution.

Seafloor Displacements Across the Mid‐Ocean Ridge Eruption Cycle Modulated by Mush Zone Viscosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Mid‐ocean ridges (MORs) are active volcanic systems where axial magma lenses (AMLs) are replenished on decadal time scales, enabling frequent dike intrusions. The associated seafloor deformation, however, remains scarcely understood. Here we assess this deformation by simulating cycles of steady AML inflation followed by instantaneous dike ...

Tectonic Controls on Volcanism and Associated Hydrothermal Activity in a Sediment‐Dominated Mid‐Ocean Ridge; Escanaba Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Mid‐ocean ridges, the Earth's most extensive volcanic system, exhibit unique characteristics in sediment‐dominant environments. Thick sediment cover insulates the crust and channels fluid along pathways that can lead to the formation of distinct crustal alteration patterns, exceptionally large mineral deposits, and specialized chemosynthetic ...

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...

Penguins on the Move: Mapping Priority Penguin Habitat Areas Under Climate Change

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim To identify and map Priority Penguin Habitat Areas (PPHAs), defined as marine regions that are environmentally suitable for penguins under present and future climates, in order to inform climate‐smart conservation planning across Southern Hemisphere. Location Marine realms of the Southern Hemisphere. Methods We modelled occurrence data for
