Summary: This study presents the first systematic volcanic hazard assessment of the remote Jan Mayen Island and discusses the challenges and characteristics of assessing volcanic hazards on remote volcanic islands. Using field data, remote images, topographic data, past data, and computer simulations, the study evaluates the probability of new vents, estimates eruption recurrence rates, simulates eruption scenarios, and produces hazard maps for different scenarios.

Summary: This paper aims to highlight the advances and challenges on marine geohazards. The author presents an overview of marine geohazard research based on bibliometric analysis and their understanding as an engineering geologist. The paper summarizes marine geohazard research in terms of development phase, authorship distribution, related areas and disciplines, keywords, and subjects of interest. The trends of past events, present processes, and future marine geohazards are discussed. Finally, three recommendations for scientific research and safeguarding society are provided.

Summary: This study presents a comprehensive long-term volcanic hazard assessment for the volcanic island of Jan Mayen, which is the northernmost active volcanic area in the world. The study evaluates the dispersal and concentration of volcanic ash in the air and provides probability maps for decision-makers and aviation stakeholders to assess and prevent the potential impact of a future ash-rich eruption at Jan Mayen.

Summary: This study identifies the main geomorphologies and processes offshore Madeira Island below 3800 m water depth, shaped by the interaction between Antarctic Bottom Water, turbidity currents, and oceanic reliefs. The distribution of morphological features defines three regional geomorphological sectors.

Summary: Commercially exploitable concentrations of Atlantic cod were found on the shelf around Jan Mayen in 2018. In the period of 2019-2021, an exploratory cod fishery was conducted, resulting in a total catch of 1737 tonnes. This area had minimal cod catches before 2018, with the first records of cod fishery dating back to the early 1930s. Cod spawning was documented for the first time in this area in 2019-2020.

Summary: Wild fish from an estuary of the NE Atlantic coast were found to be heavily contaminated by microplastics, with a majority of them being fibers and particularly high concentrations in the gastrointestinal tract. This highlights the urgent need for further research on plastic pollution in estuaries.

Summary: The translated article discusses the decline of key species populations in the Mediterranean-Atlantic marine forests, as well as the significant decrease in Sargassaceae populations on Madeira Island over the past 20 years. The study highlights that the high anthropogenic pressure on the southern coast of the island is a major factor contributing to the decline of these species.

Summary: The research focuses on the potential sources and pathways of plastic particles reaching the Macaronesian archipelagos, with results showing the North Atlantic subtropical gyre as a key feature. All archipelagos are significantly connected to areas of intensive fishing activity, with the east coasts of Central and North America serving as the main sources of land-based particles.

Summary: This study aims to understand the habitat use of the northern bottlenose whale in the Northeast Atlantic and predict its habitat use around Jan Mayen Island, Norway. The study found that the Jan Mayen habitat is a hotspot for the presence of bottlenose whales in early summer. Habitat models were created to predict habitat use based on environmental variables and field observations. The study highlights the importance of steep and deep bathymetric features in shaping the habitat use of this deep-diving species.

Summary: The settlement of maritime disputes is a significant issue for many countries, and selecting the appropriate method is crucial. International conciliation could be the preferred choice as it offers advantages such as flexibility in applying law and lower political and time costs. The success of conciliation depends on factors like the parties' willingness, external pressure, economization of delimitation, and the capacity of the commission involved. The successful settlement of the maritime dispute between Norway and Iceland during the Cold War demonstrated the value of conciliation in resolving such disputes and promoting international relations.

Summary: The Jan Mayen Channel, located in the Nordic Seas, plays a crucial role in the exchange of volume, heat, and freshwater between the Greenland and Norwegian basins. Through observations in the region, researchers have identified the key features and variability of currents, temperature, and salinity, highlighting the Jan Mayen Current as part of a complex system of currents in the area.

Summary: The study found that marine debris on Alegranza Island mainly comes from maritime traffic in Asia, with plastic products being the most abundant. Additionally, lobster trap license labels from the east coast of the United States and Canada indicate the long lifespan of these debris in the ocean.

Summary: Alzheimer's disease (AD), a neurodegenerative disease, affects the elderly and manifests as impairments in memory, language, cognition, visuospatial skills, and executive function. Current drugs slow down AD progression and relieve symptoms but cannot cure the disease. The pathogenesis of AD is unclear, but it is associated with beta-amyloid expression. Marine natural products have shown promise as potential drug candidates, with polysaccharides, carotenoids, polyphenols, sterols, and alkaloids presenting neuroprotective effects. Research is ongoing to discover novel and efficacious drug compounds for AD.
