Summary: This study used Ambient Noise Tomography (ANT) for the first time on Gran Canaria island to analyze the geological structures and geothermal potential. The findings revealed five velocity anomalies related to the island's geology and geothermal potential. Two high-velocity anomalies in the central part of the island were interpreted as intrusive volcanic bodies from the island's early stages. Three low-velocity zones were identified, potentially associated with recent volcanic activity. The study also observed a spatial correlation between anomalies in electrical conductivity and lateral gradients in the S-wave velocity model, providing evidence of hydrothermal circulation and thermal anomalies.

Summary: Plastic pollution is a current environmental problem in the Canary Islands. However, there is a lack of studies evaluating the impact of plastics on the local avifauna. In this study, the gastrointestinal tracts of 88 birds from 14 species were examined for plastic ingestion, and their livers were analyzed for the presence of various organic pollutants. The results reveal a high frequency of plastic ingestion in Cory's shearwaters, with most of the ingested items originating from fishing gear. Furthermore, the presence of organic pollutants such as PCBs, PAHs, and OCPs was detected in all or most of the samples. These findings highlight the threats posed by plastic debris and organic pollutants to seabirds in this region.

Summary: By utilizing new gravity data and marine gravity data, a 3D gravity sources model of Gran Canaria Island has been derived to investigate the geological structures beneath its surface. The density model identifies structures related to different volcanic stages, revealing the evolutionary history of Gran Canaria.

Summary: This study presents a Bouguer anomaly gravity map of Gran Canaria Island based on a new gravity data set and marine gravity data. Using gravity inversion, the study investigates the structures beneath the island's surface and derives a 3D gravity sources model. The results show different structures related to volcanic stages, magma plumbing systems, and low-density bodies in the center and shallow areas of the island.

Summary: This study examines the water footprint of different water collection and wastewater treatment facilities in the Canary Islands and finds high percentages of drinking water losses, with wells and distribution networks having the largest blue water footprint. Wastewater treatment plants also contribute to the gray water footprint. To reduce the water footprint, it is essential to optimize water resource utilization, improve infrastructure, and implement a circular economy.

Summary: The current sea level rise and an increase in the frequency and severity of sea storm events will have important environmental impacts on coastal tourist areas in oceanic islands. This study analyzes the current and future conditions of southwest sea storm events and their effects on tourist zones using mapping and high-resolution data. The results show an increase in the frequency of events, especially since the 1990s.

Summary: This study highlights the importance of submesoscale features in impacting the distribution and variability of phytoplankton in the ocean. Observational evidence is lacking for the complexity of short-term phytoplankton distribution and variability, which has been mainly inferred from theoretical and modeling approaches. The results suggest that both temporal and spatial variability may equally contribute to the total variance of picoplankton community in the mixed layer, with time being the principal contributor to variance in the deep chlorophyll maximum (DCM).

Summary: This study aimed to determine the feasibility of large-scale cultivation of Tetraselmis striata in different open ponds in Gran Canaria. The results showed high biomass productivities and photosynthetic efficiencies, with the selected strain being fast-growing and able to maintain stable biomass productivities during long-term cultivation. The biomass obtained is a good source of proteins and nutritionally important fatty acids, with potential for further improvement in ash content reduction.

Summary: Analysis of a 4,800-year sedimentary sequence from Gran Canaria revealed that before human settlement, pine pollen dominated the landscape, with dry pine forests in the highlands experiencing temporary declines and prompt recoveries. After human settlement, there was a decline in pine forests and an increase in charcoal levels, indicating increased human pressure on the island.

Summary: In order to understand the relationship between past peoples and the sea on oceanic islands, various factors such as traditions, ways of life, sailing ability and knowledge, diet, and more need to be considered. This study examines the link between external auditory exostosis (EAE) and the aboriginal population of Gran Canaria, taking into account variables such as chronology, territory, social dynamics, and environmental changes. The analysis reveals a high prevalence of EAE (17.1%) among the population, particularly among coastal communities, during the 13th to 15th centuries. These findings indicate significant variation in the relationship between these populations and the sea over more than a millennium.

Summary: This study explores the impact of North Atlantic storms on a Late Pleistocene rocky shoreline formed by basaltic rocks on a volcanic peninsula in Gran Canaria. Results show that wave heights of approximately 4.2 to 4.5 meters eroded the coastline, with larger waves needed to extract the basalt boulders. Fossil marine biota associated with the boulder beds suggest a littoral to very shallow water setting around 125,000 years ago.

Summary: The study investigates the effectiveness of the Q-LavHA algorithm in simulating lava flows in Gran Canaria and finds that the probabilistic Maximum Length constraint provides the best simulations. Most simulations almost entirely overlap with the actual lava flow, with some cases of relatively high overestimated areas and generally low underestimated areas.

Summary: Africa is the main source of dust in the world today, and dust storms frequently deposit sediment on the Canary Islands. Through the study of Pleistocene aeolian sands on Lanzarote and Fuerteventura, it was found that soils on these islands are formed from both locally derived basalt and African dust, with potential dust sources from both the Sahara and Sahel regions. Accretionary-inflationary profile development, from dust accretion, is evident in the upward growth of Canary Islands paleosols.
