                                                The Histoire physique de la mer, written by Luigi Ferdinando Marsili in 1725, was one of the first treatises to analyse the science of the sea. However, it is difficult to understand Marsili's original data. This paper reports the results of a major effort that has been undertaken to re-evaluate Marsili's observations, converting historical measurements into modern units – water weight to water density – with bathymetric profiles mapping the locations where these measurements were made and sea level variations alongside consideration of the associated error.

                                                We found extreme drops in oxygen levels in the tropical Atlantic linked to surprisingly long-lived, small subsurface eddies. These eddies are hidden beneath the surface (undetectable by satellites) and are unusually stable, even in the highly dynamic ocean near the equator. Using long-term measurements and computer models, we show that these features can strongly influence oxygen supply and potentially impact marine ecosystems.

                                                Volcanic lakes have been recognized as a rare but devastating source of disasters after the limnic eruption of Lake Nyos in 1986. The potential risk of Lake Albano (20 km southeast of the centre of Rome, Italy) is due to exposed elements (people presence, economic and touristic activities). The 3D modelling of the lake dynamics is crucial to investigate the lake stratification and degassing and the current and future behavior and stability of Lake Albano.

                                                This data review is about the reprocessing of historical eXpendable BathyThermograp (XBT) profiles from the Ligurian and Tyrrhenian seas over the time period 1999–2019. A new automated quality control analysis has been performed starting from the original raw data and operational log sheets. The data have been formatted and standardized according to the latest community best practices, and all available metadata have been inserted, including calibration information and uncertainty specification.

                                                The  powerful jets of currents induced by vessels' propellers in ports often cause areas of erosion and deposition, strongly impacting the port's operability. The capacity to fully understand and predict these complex dynamics would be a fundamental help for port operators in order to optimize and efficiently plan port management and seabed maintenance. In the present work, we show how this is possible using high-resolution modeling of hydrodynamics and sediment transport.

                Short summary
            We analyze the geostrophic circulation and tidal effects in the Gulf of Gabès from 30 years of altimetry data (1993–2022) and the outputs of a high-resolution ocean model for the year 2022.
