Summary: The study reveals the presence and distribution of microplastics in the ocean, showing that microplastics are present at least up to 1150 meters deep in the water column of the Atlantic Ocean, with noticeable seasonal differences observed at the Northeastern Atlantic Subtropical Gyre. The spatial distribution of these microplastic fragments and fibers is mainly related to ocean dynamics and mesoscale convective flows, overcoming the motion induced by their buoyancy.

Summary: This study describes the distribution and composition of mesopelagic cephalopod communities in different deep scattering layers in the Canary Islands. The results show that there are differences in cephalopod community assembly between shallow and deep scattering layers, but no differences among the sampled islands. This suggests the existence of vertical segregation but not horizontal segregation of small cephalopod species in the Canary Islands.

Summary: The study suggests that spawning zones may be a universal trait of Atlantic cod and not limited to specific environments or migratory behaviors. Age at maturity derived from spawning zone data shows similar trends to gonad maturity stages, but there is a lag of one to two years between spawning events and sexual maturity, likely reflecting a stabilization of energy partitioning.

Summary: The study focused on the recently described species Fucus guiryi, which shows distinct differences in morphology and structure compared to other closely related species distributed further north. Anatomical features and distinctive characteristics were observed in F. guiryi, indicating its adaptation to the warmer environment in the Canary Islands.

Summary: This study investigates the reproductive status of wahoo in the eastern-central Atlantic, specifically around the Canary Islands. It documents the first described breeding activity of wahoo in the eastern Atlantic, confirming the spawning activity in this region. The study found that only mature individuals spawn around the Canary Islands, with females spawning mainly during a 4-month period in summer.

Summary: Canary Islands, known for its diverse algae species and climatic conditions, is facing increasing marine pollution due to human activities. The red algae species, Asparagopsis spp. and Liagora spp., have been identified as potential bio-indicators of marine pollution. The analysis of samples collected from the southern coast of Tenerife revealed high concentrations of trace elements, indicating a significant contamination scenario in the area.

Summary: This study provides the first evidence of genetically confirmed bluefin tuna larvae in the southern Bay of Biscay, indicating bluefin spawning activity outside the Mediterranean Sea in the northeastern Atlantic. However, the results suggest that bluefin spawning in the Bay of Biscay is a sporadic phenomenon.

Summary: A comprehensive characterization of atmospheric aerosols in the subtropical eastern North Atlantic has been conducted based on long-term ground-based Aerosol Robotic NETwork (AERONET) observations. The study provides important information on the evolution of aerosols during their path from Africa to Northern Europe.

Summary: The study found that sediment samples near La Palma island mainly contained microfibers, predominantly white/colorless and blue in color, with an average length of around 2423 mm and an average concentration of 2682 items per kg of dry weight, predominantly cellulose-based. While no significant differences were found in sediment depths, significant variations were observed between sampling sites on the east and west of the island.

Summary: For the first time, four dedicated hydrographic cruises were carried out in 2015 around the Canary Islands to determine the seasonality of the flows at the eastern boundary of the North Atlantic Subtropical Gyre. The results show that the Canary Current has a seasonal behavior, flowing on the easternmost position in winter and on the westernmost position in fall. At the Lanzarote Passage, the dominant flow is southward except in fall, where a northward transport is observed.

Summary: Fish species that spawn on the sea floor may deposit their eggs in multiple layers, which can negatively impact the survival of the eggs. The survival rate of eggs decreases with an increasing number of layers, and the mortality of eggs in the surface layers increases with an increasing number of layers underneath. However, the packing density of eggs in a single layer does not affect fertilization success or egg mortality. This multiple layer deposition may be due to the decline and fragmentation of coastal vegetation, and it has the potential to negatively impact the hatching success of demersal spawning fish species such as herring.

Summary: The southern Gulf of St. Lawrence (sGSL) is considered as the primary spawning area for northern contingent West-Atlantic mackerel. However, there are indications of spawning occurring outside the sGSL. This study aims to review the potential importance of external regions for mackerel spawning based on a weight of evidence approach and found that despite some evidence of spawning in other regions like the Scotian Shelf, the sGSL remains the dominant spawning area for northern contingent mackerel.

Summary: Island archaeology is well-established, but African contributions are scarce. The Canary Islands are unique for their long history of occupation and extensive archaeological research. However, most of the research has focused on Canarian issues and lacks a broader comparative perspective. This study synthesizes existing knowledge and proposes further research opportunities in island archaeology.

Summary: This study investigates the seasonal evolution of atmospheric aerosol extinction and meteorological vertical profiles in Tenerife, Canary Islands over the period 2007-2018. The results reveal different patterns of dust transport and describe the vertical distribution of dust in the Saharan Air Layer (SAL) over this region. The study highlights the important role of both dust and water vapor in the radiative balance within the SAL during summer and winter. Furthermore, the study suggests a potential impact of the SAL on heterogeneous ice nucleation processes.

Summary: Individuals of the invasive alien seaweed Sargassum muticum have been found drifting off the coasts of Lanzarote, Canary Islands, with the nearest known populations located in Morocco. Although there were no attached individuals found, the release of reproductive materials from fertile individuals could initiate invasion processes, emphasizing the importance of surveys and monitoring to prevent population development. Rapid detection of individuals is crucial for managing and eradicating colonizing Sargassum to prevent it from becoming invasive in the region.

Summary: This study investigated the muscle of 11 cephalopod species caught in the Canary Islands, finding statistically significant differences in element concentration among class sizes and habitats. Large and elusive cephalopod species were found to have high loads and variability in Fe and Al, while coastal species had higher Zn loads. The metal contents were dominated by Fe, Ni, Al, Zn, and Sr in large and elusive cephalopod species, which can transfer these elements to predators such as deep-diving odontocetes in the Canary waters.

Summary: This study systematically reviewed and updated the cephalopod species diversity in the Canary Islands, revealing 85 confirmed species, representing approximately 10% of the overall known cephalopod diversity globally. The cephalopod community in the area was dominated by oceanic species, with shelf-slope and coastal species also present.
