Summary: The Canary Islands have experienced two volcanic eruptions in the last decade: a submarine eruption in El Hierro in 2011-12, and a subaerial eruption in La Palma in 2021. Necropsies of fish specimens from El Hierro and La Palma revealed pathological findings associated with both eruption styles. During the submarine eruption, high mortality and congestion in various organs were observed in fishes, while fishes near the lava deltas of the subaerial eruption showed increased mortality, ash particles in their gills, and intestinal impaction with volcanic material.

Summary: This study aimed to test the effects and consequences of the eruption of the volcano on the Spanish island of La Palma on 502 participants. The results found that this natural disaster predicted reductions in pro-ecological attitudes and sense of place, and increases in stress levels. The findings have important implications for the development of public policies for environmental sustainability.

Summary: This study analyzes the volcanic rocky coast setting and assesses the effects of volcanic construction and erosion on the coast at the scale of a volcanic edifice. El Hierro Island exemplifies an active sea-cliff profile, reflecting its early evolutionary stage as a young ocean volcanic island. The age of eruptions forming lava deltas affecting the coastal landform was constrained using a contemporary insular shelf. The study provides valuable insights for coastal planning and volcanic risk assessment.

Summary: The aim of this study is to understand the physical properties of volcanic ash in the Canary Islands and find a simple method to predict their hydraulic behavior. The study found that particle size greatly influences the hydraulic properties of volcanic ash, and particle sizes smaller than 1mm show the best correlation to air:water ratios and have the best predictive capacity for air-related relations.

Summary: This study provides detailed data on terrestrial gamma absorbed dose rates and the spatial distribution of gamma-emitting radionuclides in soils, including 40K, 226Ra, 232Th, and 137Cs, for the first time in the Western Canary Islands. The average terrestrial absorbed dose rate was slightly higher than that of the Eastern islands and close to the world's average, with some soil samples showing relatively high 137Cs activity concentrations. Complementary radiometric data suggested additional contributions of 137Cs from Saharan dust storms.

Summary: Emerging pollutants (EPs) refer to substances in wastewater that have not been studied, leading to uncertainties in regulations. Areas highly reliant on groundwater resources, such as El Hierro, are at risk of EP contamination. A study conducted in El Hierro revealed the presence of UV filters, UV stabilizers/blockers, and pharmaceutically active compounds (PhACs) in groundwater, with La Frontera being the most contaminated municipality. Different installations, such as piezometers and wells, showed higher EP concentrations, and sampling depth positively correlated with EP concentration. It is crucial to implement remediation measures and prevent EPs from entering the water cycle.

Summary: The study aims to characterize the mineral assemblage formed by ephemeral fumarolic fields of the Tajogaite volcano in La Palma Island, Canary Islands, Spain in 2021. A total of 73 samples were obtained from different fumarole sectors in the studied area. The mineralization associated with these fumaroles formed efflorescent patches that varied in color and were located at different distances from the volcanic craters. The mineralogical and textural characterization revealed a complex mineral assemblage comprising cryptocrystalline phases related to low and medium temperature conditions. The classification of three different fumarolic mineralization types was proposed based on their composition and occurrence.

Summary: The main source of drinking water in Tenerife is groundwater, which is extracted through an extensive network of galleries and wells. The volcanic context of the island can lead to increased radionuclide concentration activity in the groundwater. However, the measured radionuclide activity concentrations in the groundwater of Tenerife are below the recommended levels. Therefore, the contribution of groundwater to the effective dose for different age groups is within the safe range.

Summary: This paper investigates the impact of volcanic dykes on the depth of the saline interface in coastal and island aquifers, as well as their influence on the availability of fresh groundwater. The study demonstrates that volcanic dykes increase the hydraulic gradient and the depth of the saline interface, leading to increased fresh groundwater reserves inland. The results also show that correctly locating production wells in areas affected by dykes can prevent salinization of groundwater. These findings are crucial for the management of fresh groundwater resources in coastal volcanic aquifers, particularly on volcanic islands such as the Hawaiian Islands or the Macaronesian archipelagos.

Summary: This study aims to investigate the water footprint (WF) of banana and avocado crops in the Canary Islands and make recommendations for improving irrigation practices for greater food sovereignty. The results show that the average WF for bananas is 340.80 m³ t(-1) & PLUSMN; 34.07 and for avocados is 1741.94 m³ t(-1) & PLUSMN; 286.16. The proposed WF models can explain 92% and 86% of the total variance of the WF for banana and avocado crops, respectively. This research provides useful insights for farmers to reduce the WF and adapt to changing climate conditions.

Summary: Aquifers are vital sources of freshwater on oceanic islands. With growing demographic and climatic changes, it is crucial to maintain groundwater quantity and quality. However, assessing water resources on islands with heterogeneous volcanic aquifers is challenging. This study proposes an approach using recession coefficients from deep water gallery discharge to improve the hydrogeological characterization of these systems. By evaluating hydrographs and recession curves from groundwater discharge on La Palma, the main hydrogeological parameters of the volcanic aquifer system were obtained. The methodology has proven useful in addressing local uncertainties in hydraulic characterization and provides valuable information for water management planning.

Summary: On 19 September 2021, a new monogenetic volcano erupted on the Island of La Palma. It formed a pyroclastic cone and lava flows that reached the Atlantic Ocean. The environmental conservation of this volcanic landscape is important due to high anthropogenic pressure on land uses. Comparative and numerical methods were used to assess its geological value and support its protection.

Summary: Industrial seabed mining can have significant impacts on marine ecosystems, including physical disturbance and the generation of toxin-laden water. A field experiment conducted in Portman Bay showed that mine tailings resuspension and deposition led to a decline in prokaryotic abundance and nematode biodiversity, as well as changes in biogeochemical cycles and accelerated carbon degradation rates.

Summary: Over the past decade, Multibeam Echosounders (MBES) have become one of the most used techniques in sea exploration. In this paper, an algorithm for decorrelating water column and bathymetry data is proposed, and it is integrated into the FAPEC data compressor for preprocessing. The results show that FAPEC achieves good compression ratios and quality of reconstructed water column images at high speeds.

Summary: Submarine landslides can cause destruction to seafloor infrastructures and trigger devastating tsunamis. This study re-analyzes a relatively small landslide near the Balearic Islands using high-resolution 3D reflection seismic data, providing detailed images of the landslide structure. The study reveals that the landslide is composed of source areas, translational domains, and deposition areas, with the rapid deposition deforming the underlying sediments. Additionally, the study suggests that the landslide evolved in two failure stages over tens of thousands of years.
