Short summary
We use experiments and a model to study the effects of confinement width and the inflow-to-sediment discharge ratio on the evolution of submarine braided channels. We find that confinement width controls most of the morphological changes. These trends are consistent for submarine braided channels both with and without confinement width effects and similar to fluvial braided rivers. Furthermore, we built a model that can simulate the flow bifurcation and confluence of submarine braided channels.

Climate change threatens biodiversity, especially that of arthropods, by altering species' habitats and ecological roles. This study presents a proof of concept for a novel index that models species distributions based on climatic niches, using regional climate model data and focusing on Mediterranean arthropods. The index enables quick assessments of species' climate resilience and offers potential applications for projecting ecological impacts of future climate changes.

Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of environmental parameters along a fibre optic cable. Here, we review the recently emerged applications of DOFS in physical oceanography, and offer a perspective on the technology’s potential for future growth in the field.

Dense Shelf Water Cascading (DSWC) is an oceanographic process where dense shelf water rapidly spills over the shelf edge and cascades into the deep ocean. Using a high-resolution model that incorporates real observations from the water column and sea surface (MedSea Reanalysis), this study compares over 30 years of simulated intense DSWC with actual observations in the NW Mediterranean. We identified all the cascading events since 1987, with results closely matching the observations.

This study examines dense shelf-water and sediment transport in the Cap de Creus Canyon during the mild winter of 2021–2022, using multiplatform-observational data and the MedSea Reanalysis model. Results show dense shelf waters on the shelf and upper canyon, contributing to Western Intermediate Water. The canyon acts as a partial sink, with most dense water transport occurring along the coast. These events are expected to increase with climate change, favoring intermediate-water formation.

Short summary
Predicting the extent and thickness of debris flow deposits is important for assessing and mitigating hazards. We propose a simplified mass balance model for predicting the morphology of terminated debris flows depositing over complex topography. A key element in this model is that the termination of flow of the deposit is determined by prescribed values of yield stress and friction angle. The model results are consistent with available analytical solutions and field and laboratory observations.

Short summary
Groundwater flows at the land–ocean transition and the extent of freshened groundwater below the seafloor are increasingly relevant in marine sciences, both because they are a highly uncertain term of biogeochemical budgets and due to the emerging interest in the latter as a resource. Here, we discuss our perspectives on future research directions to better understand land–ocean connectivity through groundwater and its potential responses to natural and human-induced environmental changes.

Short summary
This study explores the creation of submarine canyons and hanging-wall fans on active faults, which can be defined by gravity-dominated breaching and underflow-dominated diffusion processes. The study reveals the self-similarity in canyon–fan long profiles, uncovers Hack’s scaling relationship and proposes a formula to estimate fan volume using canyon length. This is validated by global data from source-to-sink systems, providing insights into deep-water sedimentary processes.
