“…1c). The presence of such a background abyssal current in the region is consistent with previous studies 5,6,13,14,20 suggesting that, as a part of the EMT, waters of Aegean origin replaced waters of Adriatic origin in the abyssal plain of the Ionian basin (see Fig. 1b).…”

“…We note that Manca et al 15,20 observed the arrival of deep water of Adriatic origin at the base of the Sicily escarpment during 1991 that was possibly able to produce some reversals in the main bottom flow, which, at the time, was dominated by an anticyclonic motion. However, these authors also pointed out that during 1999 the region was still occupied by waters of Aegean origin, as confirmed by other studies 14,30 .…”

“…1b). Note that, in addition to this shift, which could belong to a part of a larger mode of variability of the EM 21 , a substantial mesoscale, interseasonal and interannual variability exists in EM water masses formation and circulation 5,6,13,14,20,22 .…”

Abyssal undular vortices in the Eastern Mediterranean basin

Abyssal temperature and velocity observations performed within the framework of the neutrino mediterranean observatory, a project devoted to constructing a km 3 -scale underwater telescope for the detection of high-energy cosmic neutrinos, demonstrate cross-fertilization between subnuclear physics and experimental oceanography. Here we use data collected south of sicily in the Ionian abyssal plain of the Eastern mediterranean (Em) basin to show for the first time that abyssal vortices exist in the Em, at depths exceeding 2,500 m. The eddies consist of chains of near-inertially pulsating mesoscale cyclones/anticyclones. They are embedded in an abyssal current flowing towards north-northwest. The paucity of existing data does not allow for an unambiguous determination of the vortex origin. A local generation mechanism seems probable, but a remote genesis cannot be excluded a priori. The presence of such eddies adds further complexity to the discussion of structure and evolution of water masses in the Em.

“…1). The lower branch of the CMOC is connected with the outflowing of the Southern Adriatic dense waters (Artegiani et al 1997a;Orlić 2001-2002;Manca et al 2002;Lascaratos 2004, 2008;Wang et al 2007;Bensi et al 2013b) in the Ionian abyssal basin. Several authors discussed that, during the EMT, the Adriatic source of Ionian abyssal waters could have been replaced by the Cretan Sea deep waters (Roether et al 1996;Roussenov et al 2001;Curchitser et al 2001;Manca et al 2003;Rubino and Hainbucher 2007;Ursella et al 2011;Rubino et al 2012;Bensi et al 2013a).…”

“…The NADDW water follows the western slope, filling large areas in the northern and middle Adriatic (including a deep Jabuka Pit) and renewing even bottom South Adriatic waters as deep as 1200 m [Manca et al, 2002;Orlić, 2001, 2002;Wang et al, 2006]. Finally, all components of sea level variations are the largest in the northern Adriatic, including tides [Janeković and Kuzmić, 2005], storm surges [Orlić et al, 1994] and Adriatic seiches [Vilibić, 2006], together causing flooding of coastal cities in the region (e.g., Venice).…”

[1] The paper deals with an intriguing dense-water breakout episode in mid-August 2004 which has been observed in the bottom layers of the oil rig located in the middle of the northern Adriatic. Various data (temperature series and vertical T-S profiles, currents, meteorological measurements, and satellite images) have been analyzed in order to understand conditions which preceded, were active, and followed the breakout episode. A stationary bottom pool of dense water, generated during the previous winter, has been suspected to be a source of the dense water observed during the breakout, with a permanent position established by a stationary northern Adriatic cyclonic-anticyclonic gyre system. The breakout lasted for 3 days, advecting the bottom waters more than 2°C colder than residing waters at the oil rig site. The main result of modeling experiments concerns the generative force for the observed breakout which was found to be a mesoscale storm that occurred over the open north Adriatic on 8 August 2004. The storm has been reproduced by the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS 1 ) atmospheric model which was then used to force the Princeton Ocean Model (POM) at the surface. Results of simulations reveal the capability of the storm to break the thermohaline fronts through the wind-induced baroclinic transport and downwelling at the exposed shorelines. This is the first study in the Adriatic which evaluates the impact of mesoscale summer storm to the sea, driving bottom layer circulation through the convergence/divergence dynamics in addition to the direct impact on the sea surface through the wind stress forcing.
