The deep waters of the western Mediterranean are known to have an almost constant trend towards higher salinity and temperature values since 1950s. Recent observations shown acceleration this tendency, which has been attributed by some authors effect propagation signal Eastern Transient, from east west. From 2004 2006 five basin‐scale oceanographic cruises evidenced a relevant change in structure Mediterranean. In less than two years whole basin filled with highly saline warm new water,...
Abstract One century of oceanographic measurements has evidenced gradual increases in temperature and salinity western Mediterranean water masses, even though the vertical stratification basically remained unchanged. Starting 2005, basic structure intermediate deep layers abruptly changed. We report here evidence reinforced thermohaline variability basin with significant dense formation events producing large amounts warmer, saltier denser masses than ever before. provide a detailed...
The Mediterranean Sea is a mid-latitude marginal sea, particularly responsive to climate change as reported by recent studies. Sicily Channel choke point separating the sea in two main basins, Eastern and Western Sea. Here, we report analyse long-term record (1993-2016) of thermohaline properties Intermediate Water that crosses Channel, showing increasing temperature salinity trends much stronger than those observed at intermediate depths global ocean. We investigate causes particular...
The biodiversity of the megabenthic assemblages mesophotic zone a Tyrrhenian seamount (Vercelli Seamount) is described using Remotely Operated Vehicle (ROV) video imaging from 100 m depth to top mount around 61 depth. This pinnacle hosts rich coralligenous community characterized by three different assemblages: (i) shows dense covering kelp Laminaria rodriguezii; (ii) southern side biocoenosis mainly dominated octocorals Paramuricea clavata and Eunicella cavolinii; while (iii) northern...
Abstract. The deep waters of the western Mediterranean Sea have become saltier and warmer for at least past 40 years rates about 0.015 0.04 °C per decade. Here we show that two processes contribute to these increases in temperature salinity. On interannual timescales, water formation events severe winters transmit increasingly salty intermediate into water. second process is a steady downward flux heat salt associated with finger mixing down through halocline–thermocline connects Levantine...
Within the complex of deep, hypersaline anoxic lakes (DHALs) Mediterranean Ridge, we identified a new, unexplored DHAL and named it 'Lake Kryos' after nearby depression. This lake is filled with magnesium chloride (MgCl2 )-rich, athalassohaline brine (salinity > 470 practical salinity units), presumably formed by dissolution Messinian bischofite. Compared Discovery, contains elevated concentrations kosmotropic sodium sulfate ions, which are capable reducing net chaotropicily MgCl2 -rich...

Summary In September 2008, an expedition of the RV Urania was devoted to exploration genomic richness deep hypersaline anoxic lakes (DHALs) located in Western part Mediterranean Ridge. Approximately 40 nautical miles SE from Lake, presence lake, which we named Thetis , confirmed by swath bathymetry profiling and through immediate sampling casts. The brine surface Lake is at a depth 3258 m with thickness ∼157 m. Brine composition found be thalassohaline, saturated NaCl total salinity 348‰,...
Abstract Deep-sea hypersaline anoxic lakes (DHALs) of the Eastern Mediterranean represent some most hostile environments on our planet. We investigated microbial life in recently discovered Lake Medee , largest DHAL found to-date. has two unique features: a complex geobiochemical stratification and an absence chemolithoautotrophic Epsilonproteobacteria, which usually play primary role dark bicarbonate assimilation DHALs interfaces. Presumably because these features, is less productive...
The potential impact of rapidly‐evolving submesoscale motions on relative dispersion is at the forefront physical oceanography, posing challenges for both observations and modeling. A persistent coastal front driven by river outflows in North‐Western Mediterranean Sea targeted two observational cruises conducted summer 2010. frontal zone sampled using drifters launched with a multi‐scale strategy consisting modules triplets, released either side small boats. This experiment original that...
The marine pelagic zone situated > 200 m below the sea level (bls) is largest subsystem, comprising more than two-thirds of oceanic volume. At same time, it one least explored ecosystems on Earth. Few large-scale environmental genomics studies have been undertaken to examine phylogenetic diversity and functional gene repertoire planktonic microbes present in mesopelagic bathypelagic environments. Here, we description deep-sea microbial community thriving at 4900 depth Matapan-Vavilov Deep...
Ocean acidification is thought to be a major threat coral reefs: laboratory evidence and CO2 seep research has shown adverse effects on many species, although few are resilient. There concerns that cold-water corals even more vulnerable as they live in areas where aragonite saturation (Ωara ) lower than the tropics falling rapidly due emissions. Here, we provide net (gross calcification minus dissolution) gross rates of three common corals, Caryophyllia smithii, Dendrophyllia cornigera,...
We analysed in situ CTD data collected on 36 joint Tunisian–Italian oceanographic cruises the Tunisia–Sicily Channel (Cap Bon–Mazara del Vallo section) from 1995 to 2009 order identify water masses region and estimate interannual variability of their hydrological characteristics. Besides well-known AW (Atlantic Water) LIW (Levantine Intermediate Water), other have been identified though presence is neither as steady nor stable aforementioned ones. The WIW (Western flows beneath towards...
Abstract. The long-term monitoring of basic hydrological parameters (temperature and salinity), collected as time series with adequate temporal resolution (i.e. a sampling interval allowing the all important timescales) in key places Mediterranean Sea (straits channels, zones dense water formation, deep parts basins), constitute priority context global changes. This led CIESM (The Science Commission) to support, since 2002, HYDROCHANGES programme...
Thermohaline staircase structures are commonly observed in the western Mediterranean Sea within halocline-thermocline connecting Levantine Intermediate Water at about 400 m depth with deep waters below 1,500 m. In this where warmer, saltier overlie colder, fresher waters, salt finger mixing processes thought to be active and produce staircases layers of order 75 thickness containing nearly constant properties separated by sharp steps 6 jumps between layers. While have salinity, potential...
Abstract The longest historical time series (14 years, from 2003 to 2016) of temperature and salinity thermohaline staircases with highly homogeneous reliable data ever observed is here presented studied. staircase system the central Tyrrhenian Sea due double diffusion in salt finger regime, our study reveals its conservative behavior, oscillating among slightly different shapes, passing through merging processes, a systematic upward drift interfaces. Data also show enhanced processes after...
Abstract. EXpendable BathyThermograph (XBT) temperature profiles collected in the framework of Mediterranean Forecasting System – Toward Environmental Prediction (MFS-TEP) project have been compared with CTD measurements. New procedures for quality control recorded values developed and checked. Some sources possible uncertainties errors, such as response time apparatus (XBT probe, thermistor readout chain), or influence initial conditions are also analysed. To deal high homogeneity waters, a...
Abstract. For the first time it was possible to investigate a still poorly known region of eastern Mediterranean Sea, Libyan continental margin. An oceanographic cruise, performed during summer 2006, revealed an important and novel feature: dense vein flowing along slope. The paper describes evolution with some insights on its dynamic furnishes estimate transport, which results be comparable Adriatic Deep Water production rate. cascading into steep canyon incises shelf suggests that may play...
