Considering the relevance and impact of river discharges on the coastal environment, it is necessary to understand the processes associated with river plume dynamics in different regions and at different scales. Modeling studies focused on the eastern Pacific coast under the influence of the Humboldt Current are scarce. Here, we conduct for the first time an interannual modeling study of two river plumes off central Chile and discuss their characteristics.

The Algerian Basin plays a key role in the WMED, and the formation and propagation of mesoscale structures strongly influence its circulation. They transport water masses, heat, salts and other properties and also have an impact on chlorophyll and fisheries. We investigated the spatial and temporal distribution of the eddies by applying a detection and tracking method to altimetry data. The results show mesoscale structures with different origins, behaviours and energies.

Major differences can be observed in areas with large mesoscale activity.
Results suggest that surface currents component in fluxes computation should not be neglected even at such scales and latitudes.

Over 100 experiments were realized between 1998 and 2022 in the Mediterranean Sea using surface coastal and offshore Lagrangian drifters. Raw data were initially unified and pre-processed. Then, the integrity of the received data packages was checked and incomplete ones were discarded. Deployment information was retrieved and integrated into the PostgreSQL database. Data were interpolated at defined time intervals, providing a dataset of 158 trajectories, available in different formats.

Over 1468 hydrological vertical profiles were acquired in 21 years in the Mediterranean Sea. This allowed us to follow the diffusion of the Western Mediterranean Transient along all western seas or make some important repetitions across straits, channels, or at defined locations. These data are now available in four open-access online datasets, including profiles of water temperature, conductivity, dissolved oxygen, chlorophyll α fluorescence, and, after 2004, turbidity and pH.

The city of Venice relies crucially on a good storm surge forecast to protect its population and cultural heritage. In this paper, we provide a state-of-the-art review of storm surge forecasting, starting from examples in Europe and focusing on the Adriatic Sea and the Lagoon of Venice. We discuss the physics of storm surge, as well as the particular aspects of Venice and new techniques in storm surge modeling. We also give recommendations on what a future forecasting system should look like.

Correct surface ocean circulation forecasts are highly relevant to search and rescue, oil spills, and ecological processes, among other things. High-frequency radar (HFR) is a remote sensing technology that measures surface currents in coastal areas with high temporal and spatial resolution. We performed a series of experiments in which we use HFR observations from the Ibiza Channel to improve the forecasts provided by a regional ocean model in the western Mediterranean.

From May 2000 to January 2004 seven cruises in the Sea of Sardinia collected physical, chemical and biological data. They contributed to knowledge of the local circulation and its interaction with the general Mediterranean one. Accurate and sustained quality assurance for physical sensors was ensured through pre- and postcruise calibration (described here) and verified during cruises by redundant sensors and instruments. Hydrological data are in two open-access datasets in the SEANOE repository.

Diel vertical migration (DVM) is a survival strategy adopted by zooplankton that was investigated in the Corsica Channel using acoustic data from April 2014 to November 2016. The principal aim of the study is to characterize migratory patterns and biomass temporal evolution along the water column. In addition, net samples were taken during summer 2015 at the same location. During the investigated period, zooplankton had a well-defined daily and seasonal cycle, with peaks in late winter.

We present data collected from the first three glider surveys in the Algerian Basin conducted during the ABACUS project. After collection, data passed a quality control procedure and were then made available through an unrestricted repository. The main objective of our project is monitoring the basin circulation of the Mediterranean Sea. Temperature and salinity data collected in the first 975 m of the water column allowed us to identify the main water masses and describe their characteristics.

Meteocean and environmental forecasting is increasingly being used in operational decision-making in the sea for demographic, geographic and strategic applications. It also used to force the stochastic models used for search and rescue planning. The stochastic models have many limitations relating to the leeway calculation, and we tried to overcome them; we hope to contribute by providing leeway drift formulae for practical use.

An intensive drifter deployment was carried out in the Strait of Gibraltar: 35 satellite tracked drifters were released, coordinating to this aim 4 boats, covering an area of about 680 NM2 in 6 hours. This MEDESS-GIB Experiment is the most important exercise in the Mediterranean in terms of number of drifters released. The MEDESS-GIB dataset provides a complete Lagrangian view of the surface inflow of Atlantic waters through the Strait of Gibraltar and its later evolution along the Alboran Sea.

Short summary
Diel vertical migration (DVM) is a survival strategy adopted by zooplankton that was investigated in the Corsica Channel using acoustic data from April 2014 to November 2016. The principal aim of the study is to characterize migratory patterns and biomass temporal evolution along the water column. In addition, net samples were taken during summer 2015 at the same location. During the investigated period, zooplankton had a well-defined daily and seasonal cycle, with peaks in late winter.

Short summary
Zooplankton and fishes found below a depth of 200 m may perform a vertical migration to the surface waters. The migration patterns (from 400 m to the surface) of four groups of organisms were studied in the deep (1500 m) eastern Mediterranean (Cretan Sea) for 2.5 years. The lunar cycle, daylight duration, cloudiness and presence of predators and prey explain their migration variability. This phenomenon is important as it constitutes an active transport of organic matter over large distances.

Short summary
An ocean glider was tested during the REP14-MED experiment off the western coast of the island of Sardinia as a platform for recording sounds produced by whales and dolphins using two sensors. Sperm whale clicks as well as dolphin clicks and whistles were identified in the recordings. Automatically detected sperm whale clicks were used to estimate animal tracks. Such information is useful for marine mammal density estimation studies that use passive acoustics.
