Short summary
We compare seismometers with the 6C method, which combines rotational and seismometer data, determining signal directions and wave velocities for short and continuous low-frequency volcanic signals at Mt. Etna. Either the cluster or the rotational sensor reliably detect continuous signal directions, aligning with the observatory data. For short signals, 6C directions deviate more, likely due to a complex underground. Combining both methods' velocity results improves understanding volcanic waves.

We analyse 2009–2022 CTD data from 12 summer cruises on the Ligurian - Tyrrhenian shelf. Results show a decadal-scale warming and salinification down to the intermediate layer, leading to enhanced water column stratification. Changes are linked with the BIOS and the cyclonic -anticyclonic state transition of the Northern Ionian Gyre. Results underscore the role of inter-basin connectivity and climate-driven circulation dynamics in shaping the hydrography of the western Mediterranean.

This study investigated how Mediterranean cyclones impact chlorophyll-a dynamics. Using reanalysis data, ARGO floats, and satellite imagery, we found that slow-moving cyclones significantly uplift the deep chlorophyll maximum. Upwelling and air-sea heat exchange were key mechanisms driving this uplift, enhancing nutrient availability and primary productivity. These findings highlight the strong influence of cyclone intensity and movement on biogeochemical processes in the Mediterranean Sea.

Presence and interannual variability of water masses on the continental shelf around Sardinia are studied by CTD data from three cruises carried out between 2019 and 2021. For the first time the analyses are identifying the water mass phenomenology on the south-western Sardinia shelf characterized by the presence of the Atlantic Water driven by Algerian eddies. On the southern and eastern shelves, the presence of the Atlantic Water the water column is affected by the South East Sardinia Gyre.

This description and mapping of coastal sea level monitoring networks in the Mediterranean and Black seas reveals the existence of 240 presently operational tide gauges. Information is provided about the type of sensor, time sampling, data availability, and ancillary measurements. An assessment of the fit-for-purpose status of the network is also included, along with recommendations to mitigate existing bottlenecks and improve the network, in a context of sea level rise and increasing extremes.

This work reviews the existing advanced and emerging scientific and societal applications using HFR data, developed to address the major challenges identified in Mediterranean coastal waters organized around three main topics: maritime safety, extreme hazards and environmental transport processes. It also includes a discussion and preliminary assessment of the capabilities of existing HFR applications, finally providing a set of recommendations towards setting out future prospects.

High-frequency radar (HFR) is a land-based remote sensing technology that can provide maps of the surface circulation over broad coastal areas, along with wave and wind information. The main goal of this work is to showcase the current status of the Mediterranean HFR network as well as present and future applications of this sensor for societal benefit such as search and rescue operations, safe vessel navigation, tracking of marine pollutants, and the monitoring of extreme events.

Over the 20th century, shallow damaging seismicity occurred in and near the Hainaut coal mining area in Belgium. We provide an overview of earthquake parameters and impacts, combining felt and damage testimonies and instrumental measurements. Shallower earthquakes have a depth and timing compatible with mining activity. The most damaging events occurred deeper than the mines but could still have been triggered by mining-caused crustal changes. Our modelling can be applied to other regions.

Icequakes are the result of processes occurring within the ice mass or between the ice and its environment. Having a complete catalogue of those icequakes provides a unique view on the ice dynamics. But the instruments recording these events are polluted by different noise sources such as the wind. Using the data from multiple instruments, we found how the wind noise affects the icequake monitoring at the Princess Elisabeth Station in Antarctica.

Mexican seismic stations witnessed a reduction in noise level as a result of the COVID-19 lockdown strategies. The largest drop was observed in Hermosillo, which is also the city with the fastest noise-level recovery and a quick increase in confirmed COVID-19 cases. Since 1 June 2020, a traffic-light system has modulated the re-opening of economic activities for each state, which is reflected in noise levels. Noise reduction has allowed the identification and perception of smaller earthquakes.

COVID-19 pandemic lockdowns in countries with a dominant informal economy have been a greater challenge than in other places. This motivated the monitoring of the mobility of populations with seismic noise throughout the various phases of lockdown and in the city of Querétaro (central Mexico). Our results emphasize the benefit of densifying urban seismic networks, even with low-cost instruments, to observe variations in mobility at the city scale over exclusively relying on mobile technology.

The Auckland Volcanic Field is monitored by a seismic network. The lockdown measures to combat COVID-19 in New Zealand provided an opportunity to evaluate the performance of seismic stations in the network and to search for small(er) local earthquakes, potentially hidden in the noise during "normal" times. Cross-correlation of template events resulted in detection of 30 new events not detected by GeoNet, but there is no evidence of an increase in detections during the quiet period of lockdown.

During the COVID-19 pandemic, most countries put in place social interventions, aimed at restricting human mobility, which caused a decrease in the seismic noise, generated by human activities and called anthropogenic seismic noise. In densely populated eastern Sicily, we observed a decrease in the seismic noise amplitude reaching 50 %. We found similarities between the temporal patterns of seismic noise and human mobility, as quantified by mobile-phone-derived data and ship traffic data.

Short summary
In this work, we study a Mediterranean cyclone that occurred in February 2023 and its relationship with a particular seismic signal called microseism. By integrating the data recorded by seismic stations, satellites, HF radar and wavemeter buoy we are able to obtain information about this event. We show how an innovative monitoring system of the Mediterranean cyclones can be designed by integrating microseism information with other techniques routinely used to study meteorological phenomena.
