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

Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment
Abstract For the first time, the Autosub Long Range (ALR) completed a fully autonomous, long‐distance (2,000 km) scientific mission, delivering new insight into coastal carbonate dynamics and air‐sea CO2 ${\text{CO}}_{2}$ fluxes. Equipped with a suite of oceanographic sensors, including a Lab‐on‐Chip (LOC) pH sensor and a Sea‐Bird SeaFET pH sensor, the

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
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 ...
