Assessing Zooplankton Communities' Influence on Particulate Organic Carbon Concentration

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Zooplankton play a key role in setting the particulate organic carbon (POC) distribution in the ocean, but this role remains poorly quantified on large scales due to the complexity of zooplankton ecosystems and the sparsity and variability of observations.

Energy-Based Voltage Stabilization in DC Shipboard Power Systems With Dual Loop Control

IEEE Access
The electrification of shipboard power systems carries an increasing variety in power sources, energy storage systems, and power converters. DC distribution is gaining relevance due to efficiency increase, space savings, and high controllability.

Ground‐Truthed Fiber‐Optic Sensing Reveals Internal Tide Bores Over Madeira's Steep Slope

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We demonstrate the combined utility of distributed acoustic sensing (DAS) and repeat conductivity‐temperature‐depth (CTD) profiling for observing internal tide dynamics over a sloping seafloor. While DAS has been widely proposed as a method to infer ocean temperature variability from seafloor cables, quantitative in situ validation has been ...

Power System Control in DC Shipboard Power Systems: A Review of Methods and Architectures

IEEE Access
The electrification of shipboard power systems (SPSs), combined with the introduction of heterogeneous power sources and energy storage technologies, is driving a need for more advanced and structured control strategies.

Robust NN‐based backstepping control of non‐affine ferry ship fuel cell‐based DC MGs under stochastic disturbance inputs

IET Renewable Power Generation, 2022
Fossil fuels play a significant role in the automobile industry, as well as marine vessel systems, with a lot of benefits like high‐density and low‐cost power supply, which is relatively easy to reserve, apply and carry.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, Volume 24, Issue 7, July 2026.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

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 ...

Tracing the Migration of Fronts in the Pacific Southern Ocean Across the Mid‐Pleistocene Transition

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Southern Ocean is a key driver of global climate variability, yet its dynamics during the Mid‐Pleistocene Transition (MPT; ∼1.25–0.7 Ma) remain poorly understood, especially in the South Pacific sector. The Polar Frontal Zone (PFZ) underwent significant latitudinal shifts during this critical period of climate reorganization.

Constraining Sources of Mid‐Pleistocene to Present Explosive Volcanism in the Gulf of Alaska Using Machine Learning and Compositional Data Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The long‐term eruptive record of a region helps better elucidate magmatic processes at depth as well as volcanic hazards at the surface. Typically, reconstructing such records is done using proximal tephrostratigraphy and linking individual tephras to source volcanoes. These records, however, can only be accurately constructed if they are both
