Sinking microplastics at a deep-sea seamount in the North Atlantic: a year-long flux study Open
The deep sea is now known to accumulate a significant fraction of the ocean's microplastics, yet the mechanisms by which these particles are transported down to the seafloor are still poorly quantified. Here, we quantify the annual and sea…

An index to differentiate megafauna entangled in operational fishing gears from abandoned, lost, or otherwise discarded fishing gears Open
Classifying entanglements of marine megafauna in certain anthropogenic items is challenging because many are found in fishing-related items, with the cause being either operational fishing gear (OFG) or abandoned, lost, or otherwise discar…

eDNA-Based Survey of Fish Species in Water Bodies Using Loop-Mediated Isothermal Amplification (LAMP) for Application of Developing Automatic Sampler Open
The monitoring of species in a habitat is important to ensure biological diversity. Environmental DNA (eDNA) can infer the presence–absence of species and enable rapid action to avoid threatening factors in ecosystems in the case of non-in…

Anthropogenic particles determination in northern krill (Meganyctiphanes norvegica) from the Azores region: A keystone species for marine food webs Open
Plastic pollution poses a significant threat to marine ecosystems. Microfibres from fabrics have become the most prevalent shape of microplastic found in the marine environment. The northern krill (Meganyctiphanes norvegica) is the most ab…

Improving impact assessments to reduce impacts of deep-sea fisheries on vulnerable marine ecosystems Open
Robust impact assessments (IAs) for deep-sea fisheries are essential for safeguarding deep-sea ecosystems against the impacts of bottom fishing. In the high seas, United Nations Resolution commitments require States (independently or throu…
