Un objet diplomatique : l’occupation industrielle des fonds marins à travers l’analyse des décisions politiques

VertigO, 2021
This article analyzes the first controversies and the decision-making process (1982-1989) that triggered the way in which seabed’s mineral exploitation zones are distributed today among countries.

Methodology for Developing a Combined Bathymetric and Topographic Surface Model Using Interpolation and Geodata Reduction Techniques

Remote Sensing, 2021
The research in this paper is concerned with the development of a continuous elevation model in the coastal zones of inland waters. The source data for the creation of numerical terrain models were data acquired by contemporary sensors, such as such as a

Seamounts and related topographic highs – automated mapping in support of sustainable ocean management, Norway

Frontiers in Earth Science
Seamounts are a prime example of an ecologically relevant marine landform. They are internationally recognized by the OSPAR commission as a threatened and/or declining habitat yet estimates of their distribution in Norwegian waters are not adequately ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

Advanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

A Sediment Magnetic Record in the North Pacific Across the Mid-Pleistocene Transition and its Implication on Asian Dust Evolution

Frontiers in Earth Science, 2021
Eolian dust deposited in the North Pacific is an important archive of the evolutionary history of Asian interior source regions and climate system. Here, we present a ∼1 Myr sediment magnetic record from the central North Pacific to characterize eolian ...

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Subsidence of Artificial Reefs with Bamboo Foundations on a Soft Seabed

Applied Sciences
The design of artificial reefs must be based on the criteria of both durability and serviceability. In this respect, the seabed subsidence rate related to the weight of the reefs and of their foundation system should be limited.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
