In the past two decades, Argo Program has collected, processed and distributed over million vertical profiles of temperature salinity from upper kilometers global ocean. A similar number subsurface velocity observations near 1000 dbar have also been collected. This paper recounts history Program, its aspiration arising out World Ocean Circulation Experiment, to development implementation instrumentation telecommunication systems, various technical problems encountered. We describe data...

The Copernicus Marine Environment Monitoring Service (CMEMS) Ocean State Report (OSR) provides an annual report of the state global ocean and European regional seas for policy decision-makers with additional aim increasing general public awareness about status of, changes in, marine environment. CMEMS OSR draws on expert analysis a 3-D view (through reanalysis systems), from above remote-sensing data) direct interior in situ measurements) seas. is based unique monitoring capabilities blue...

Abstract. Adriatic and Ionian seas are Mediterranean sub-basins linked through the Bimodal Oscillating System mechanism responsible for decadal reversals of basin-wide circulation. Altimetric maps showed that last cyclonic mode started in 2011 but unexpectedly 2012 reversed to anticyclonic. We related this "premature" inversion extremely strong winter 2012, which caused formation very dense waters, flooding flanks May inverting bottom pressure gradient. Using Lagrangian float measurements,...
The paper aims to describe the preconditioning and observations of exceptionally high salinity values that were observed in summer autumn 2017 Adriatic. encompassed CTD measurements carried out along well-surveyed climatological transect Middle Adriatic (the Palagruža Sill, 1961–2020), Argo profiling floats several glider missions, accompanied with satellite altimetry operational ocean numerical model (Mediterranean Forecasting System) products. Typically, subsurface maximum, lower than...
[1] We analyze aspects concerning the thermohaline changes observed in near-bottom layer of Southern Adriatic Pit (SAP), Eastern Mediterranean, after arrival abundant and exceptionally dense water (σθ > 30 kg m−3) produced shallow Northern Sea during winter 2012. For this purpose, we use temperature (T), salinity (S), current time series collected at E2M3A deep-ocean observatory Adriatic, Conductivity-Temperature-Depth data obtained both Middle from freely drifting profiling floats. The...
The circulation of the Eastern Mediterranean Sea is characterized by numerous recurrent or permanent anticyclonic structures, which modulate pathway main currents and exchange water masses in basin. This work aims to describe structures thermohaline properties with particular focus on two anticyclones, Pelops Cyprus gyres, using in-situ (drifters Argo floats) satellite (altimetry) data. gyre involved Levantine origin surface intermediate waters their flow toward Ionian Adriatic Sea. Gyre...
The Mediterranean Sea is considered a hot spot of global warming because it has been changing faster than the ocean, creating strong impact on marine environment. Recent studies agree increase in sea level, surface temperature, and salinity over last two decades. In this research, possible interconnection between these other parameters that contribute to regulatory effect climate are identified discussed. Spatio-temporal variability four oceanographic air–sea interaction (sea-level,...
Abstract The attention of the scientific community, policymakers, and public opinion on Medicanes has recently grown because their increase in intensity harmful potential. Although may be influenced by pre-existing upper-ocean conditions, uncertainties remain about how such weather extremes influence ocean circulation. This work examines a condition that been never described before Mediterranean, which involves interplay between an atmospheric cyclone (Medicane Apollo—October 2021) cyclonic...
Abstract. Atlantic Water (AW) and Levantine Intermediate (LIW) are important water masses that play a crucial role in the internal variability of Mediterranean thermohaline circulation. To be more specific, their interaction, along with other characterize basin, such as Western Deep (WMDW), contribute to modify Outflow through Strait Gibraltar, hence they may influence stability global This work aims AW LIW Sea, taking advantage large observational dataset (freely available on...
The Mediterranean Sea is very sensitive to climatic changes due its semi-enclosed nature and therefore defined as one of the hotspots in future climate change projections. In this study, we use Argo float data assess climatologies trends temperature Ocean Heat Content (OHC) throughout for specific sub-basins (e.g. Western Eastern Mediterranean, Gulf Lion, South Adriatic). amount OHC, spatially averaged bins 1°x1° over period from 2001 2020, increases west east Sea.

The dynamics of dissolved oxygen in the ocean are crucial importance for understanding marine ecosystems, with influences ranging from exchange atmosphere to biological processes and circulation. In this study, we focus on southern Adriatic Sea, an essential component Eastern Mediterranean "conveyor belt", investigate long-term its driving factors. We use cross-platform datasets 2013 2020, including remote sensing data, model reanalysis in-situ observations Argo floats, gliders ship-based...
Levantine intermediate water (LIW) is formed in the Sea (Eastern Mediterranean) and spreads throughout Mediterranean at depths, following general circulation. The LIW, characterized by high salinity relatively temperatures, one of main contributors Overturning Circulation influences mechanisms deep formation Western Eastern sub-basins. In this study, LIW (LDW) processes are investigated using Argo float data from 2001 to 2017 Northwestern (NWLS), larger area around Rhodes Gyre (RG). To find...

Abstract The maximum cross-correlation (MCC) technique is utilized to estimate the Adriatic Sea surface currents in regions characterized by strong horizontal temperature gradients using sequential pairs of sea images from Advanced Very High Resolution Radiometer data collected between September 2002 and December 2003. A variety filtering techniques are used eliminate erroneous MCC-derived resulting velocity direction estimates that spatially coherent most thermal features observed. results...
The Argo observation network is made up of approximately 4,000 drifting floats, which provide valuable information about the ocean and its role in climate system. Each one these floats work continuous cycles, until their batteries run out. Due to importance operational forecasting research, community continually assesses status sensors mounted on each floats. Recovering would offer a great opportunity gain insight into sensor performance stability, although economic environmental costs...
