The OceanGliders program started in 2016 to support active coordination and enhancement of global glider activity. contributes the international efforts Global Ocean Observation System (GOOS) for Climate, Health, Operational Services. It brings together marine scientists engineers operating gliders around world: (1) observe long-term physical, biogeochemical, biological ocean processes phenomena that are relevant societal applications; and, (2) contribute GOOS through real-time delayed mode...
Abstract During winter 2012–2013, open‐ocean deep convection which is a major driver for the thermohaline circulation and ventilation of ocean, occurred in Gulf Lions (Northwestern Mediterranean Sea) has been thoroughly documented thanks particular to deployment several gliders, Argo profiling floats, dedicated ship cruises, mooring array during period about year. Thanks these intense observational efforts, we show that reached bottom early February 2013 area maximum 28 ± 3 . We present new...
Abstract Limitations of access have long restricted exploration and investigation the cavities beneath ice shelves to a small number drillholes. Studies sea-ice underwater morphology are limited largely scientific utilization submarines. Remotely operated vehicles, tethered mother ship by umbilical cable, been deployed investigate tidewater-glacier ice-shelf margins, but their range is often restricted. The development free-flying autonomous vehicles (AUVs) with ranges tens hundreds...
Abstract Since 2010, an intense effort in the collection of situ observations has been carried out northwestern Mediterranean Sea thanks to gliders, profiling floats, regular cruises, and mooring lines. This integrated observing system enabled a year‐to‐year monitoring deep waters formation that occurred Gulf Lions area during four consecutive winters (2010–2013). Vortical structures remnant wintertime vertical mixing events were regularly sampled by different platforms. These are...
Abstract Climatic changes and interannual variability in the Mediterranean overturning circulation are crucially linked to dense water formation Levantine Sea, namely Intermediate Water whose zone, comprising multiple intermittent sources, extends over fluctuating pathways. To probe into of this spreading, a unique dataset was collected during winter 2019 western via oceanographic cruises, profiling floats glider, at spatio‐temporal distribution suited resolve mesoscale features convection...
The surface circulation and the thermohaline properties of water masses eastern Levantine Sea (Mediterranean Sea) were monitored with mobile autonomous systems (surface drifters gliders) during period September 2016–August 2017. provided data for more than a year revealed complex features at scales ranging from basin scale to sub-mesoscale. Three captured in semi-permanent gyre (Cyprus Eddy) allowing quantitative study its kinematics. During experiment, three gliders operated, two different...
Abstract. The Cyprus Coastal Ocean Forecasting and Observing System (CYCOFOS) has been producing operational flow forecasts of the northeastern Levantine Basin since 2002 substantially improved in 2005. CYCOFOS uses POM model, recently, within frame MFSTEP project, model was upgraded to use hourly SKIRON atmospheric forcing, its resolution increased from 2.5 km 1.8 km. is now nested ALERMO regional University Athens, which MFS basin model. Variational Initialization FOrcing Platform (VIFOP)...
The tragic Deepwater Horizon accident in the Gulf of Mexico 2010 as well increase deepwater offshore activity have increased public interest counter-measures available for sub-surface releases hydrocarbons. To arrive at proper contingency planning, response managers urge a system instant detection and characterization accidental releases. Along these lines, this paper describes application heterogeneous robotic unmanned vehicles: autonomous underwater vehicle (AUV), surface (USV) aerial...
Beginning in March 2009, two gliders of the Oceanography Center University Cyprus (OC-UCY) began occupying a hydrographic endurance line for measurements temperature, salinity, dissolved oxygen, optical backscatter, and fluorescence Levantine Sea. The transects follow butterfly pattern near Eratosthenes Seamount, extending to maximum depth 1000 m. These operational represent first time series carried out by OC-UCY. In November joint project, "Eye Levantine," was which 6 were deployed...
Abstract In March 2003 several autonomous underwater vehicle (AUV) missions were carried out under sea ice in the western Bellingshausen Sea. Data from upward-looking acoustic Doppler current profiler (ADCP) on “Autosub” AUV indicate a strongly oscillating horizontal velocity of due to ocean swell. Swell period, height, direction, and directional spread have been computed every 800 m edge 10 km inward for three missions. Exponential, period-dependent attenuation waves propagating through was...
The authors show that vertical turbulent fluxes in the upper ocean can be measured directly with an autonomous underwater vehicle (AUV). A horizontal profile of water velocity is obtained by applying a Kalman smoother to AUV motion data. uses linearized model for and data such as depth, pitch, pitch rate produce optimal estimate state system, which includes other variables velocity. Vertical estimated from microconductivity temperature (AMTV) accurate at scales three several hundred meters,...
Abstract. The Ships Of Opportunity Program in the Mediterranean Sea was established at end of 1999, framework Forecasting System – Pilot Project (MFS-PP). Many improvements have been made data collection, transmission and management. Calibration selected XBTs a comparison vs. CTDs during some research cruises assured quality data. Transmission now allows receiving full resolution by using GSM or satellite telecommunication services; management is offering access to high view services....
The investigation of wave climate is primary concern for the successful implementation offshore aquaculture systems as waves can cause significant loads on them. Up until now, site selection and design (or selection) cage system structures extended sea areas do not seem to follow any specific guidelines. This paper presents a novel methodology identification favorable sites development in an area based two important technical factors: (i) detailed characterization climate, (ii) water depth....

The most prominent and persistent feature of the eastern Mediterranean Levantine Basin (LB) is warm anticyclonic Cyprus Eddy (CE) located above Eratosthenes Seamount (ESM). This eddy periodically couples with two smaller cyclonic eddies, South Shikmona (SSE) North (NSE), which form downstream. reason for zonal drift CE center formation mechanism CE, SSE NSE largely debated today, yet upwelling biological productivity LB can be strongly impacted by local dynamics. Using a variety research...
Increases in sea surface temperatures (SSTs) have been recorded to occur globally, with the Mediterranean SSTs rising about twice as much those of global oceans. Here we analyse and compare satellite remote sensing SST data in-situ for period 1996-2012 Eastern Mediterranean, Levantine basin. Further, temperature profiles from oceanographic cruises autonomous underwater vehicles (gliders) this region, processed study interannual variability at layer (0-10m). These were collected during...
Wavelet ridge analysis was applied to the data of drifters caught in Cyprus Gyre eastern Mediterranean Sea study surface currents at low (rotating circulation) and high (near-inertial motion) frequencies. Drifter observations indicate that orbital speed is highest about 30 km from gyre center (reaching ~45 cm/s) Rossby number can be as 0.25. Drifters also show strong near-inertial with 35-40 cm/s exceed rotation background vorticity inside generally shifts effective inertial frequency values...
Abstract. Modern ocean operational systems involve different groups and tools, in regions scales. Blending all these a unique system with reliable forecasting capabilities is an important task. The efficiency of nesting procedures between scale resolution models are crucial determining whether the dynamics at scales well represented each level or technique suppresses dynamical features emerging from individual modelling components. In present work, we investigate role initialization...
