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 analysis of the mixing processes involving water masses on Ross Sea continental shelf is one goals CLIMA project (Climatic Long-term Interactions for Mass balance in Antarctica). This paper uses extended Optimum MultiParameter (OMP), which applied to four datasets collected during cruises 1994/95, 1995/96, 1997/98 and 2000/01 (Antarctica). Data include both hydrological, (temperature, salinity, pressure; T, S, P, respectively) chemical parameters (O 2 , Si(OH) 4 PO NO 3 +NO ). OMP based...
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...
Homogeneous methods for ecological applications to the nutrient cycle are analyzed, and results presented according marine ecology work discussed. To do justice explanations, materials summarized, discussed improved both interested readers experts in field. Both serve informative popularizing as well applicable interpretive purposes and, order achieve widest possible dissemination, shared under strict supervision of earlier individual publications here. The aeolian syntheses quantify impact...
Interactions between physical and biogeochemical processes have traditionally been studied at ocean basin scales or in regions with by large mesoscale features. At finer scales, such as fronts small eddies, modeling studies offered valuable insights into how features influence biogeochemistry. However, these interactions remain understudied using empirical data due to the challenges of identifying sampling dynamic structures. In oligotrophic regions, vertical distribution nutrients plays a...
Observations beneath ice-covered oceans and within ice-shelf cavities are central to understanding the ocean-ice interactions that influence stability, contribute global sea-level change, shape large-scale ocean circulation patterns. However, direct observations in these regions, particularly those capturing wintertime conditions, remain scarce due logistical challenges posed by persistent ice cover. Emerging autonomous technologies new applications now offer opportunities address...
Abstract. In this work, the relative importance of nitrogen and phosphorus, considered as external loads, on Mediterranean biogeochemical cycles is evaluated. Biomass concentrations are analysed considering steady state response three-dimensional ECHYM model to three phosphorus atmospheric depositions, continuous in time. After reaching stationary evolutions, chlorophyll surficial maps vertical transects compared with existing datasets, showing a good agreement at their large scale sampling....
The BioSWOT-MED cruise (https://doi.org/10.17600/18002392) was designed to study the bio-physical coupling in region of North Balearic Front Western Mediterranean Sea, an area moderate fine scale energy level. took place during SWOT fast-sampling phase April-May 2023 thus providing a unique opportunity daily evolution mesoscale eddies and structures as inferred from combination with high frequency in-situ measurements.In-situ measurements were focused on front identified altimetry data Chl-a...
During the SWOT fast sampling phase in spring 2023, BioSWOTMed cruise (https://doi.org/10.17600/18002392) sampled for four weeks a front located on both western and eastern swaths of 003 pass, about 100 km northeast Menorca, Western Mediterranean Sea. The coincided to portion north Balearic front. was modulated by presence eddies small Rossby radius (of order 20-30km), not visible conventional altimetry maps. availability cloud-free images ocean color (OLCI) five consecutive days also...
The BioSWOT-Med cruise was carried out in the northwestern Mediterranean Sea during fast-sampling phase of satellite SWOT mission (fixed tracks were revisited every 24h), contributing to international efforts studying oceanic submesoscale mesoscale (1 100 km) dynamics. This region is an ideal natural laboratory for fine-scale biogeochemistry as its dynamics sustains strong contrasts associated with high production north (Gulf Lions) and oligotrophic conditions moderate energy south. used...
Dissolved oxygen (DO) is one of the most important drivers ocean biogeochemical cycles and marine life, in many areas its concentration has declined due to climate change. In recent decades, a growing number autonomous oceanographic platforms been equipped with sensors for direct situ measurements levels. However, ensure high quality comparable data, these observations need be validated or, if necessary, corrected. this paper, we compiled all available DO data collected by Argo floats...
The Ross Ice Shelf floats above the southern sector of Sea and creates a cavity where critical ocean-ice interactions take place. Crucial processes occurring in this include formation Water, coldest ocean water, intrusion Antarctic Surface main driver frontal basal melting. During winter, polynya forms along edge, producing precursor to Bottom Water known as High Salinity Water. Due difficulty direct exploration there have been only hypothesized date. Here we show thermohaline observations...
