The OGS glider team was created in spring 2007, when a shallow water
SLOCUM glider (manufactured by Webb Research Corporation) was
purchased.
This glider was named TRIESTE-1 after the famous
bathyscaphe Trieste designed by August Piccard in the 1950's.
After having performed different missions in December 2009 the
communication with TRIESTE-1 was lost in the area South of Cyprus. It
was never recovered!
In 2010, the OGS glider group conducted another mission in the
Ligurian Sea using a French glider thanks to the EGO collaboration.
In spring 2012 a SeaGlider manufactured by the IRobot (named Amerigo)
was acquired with the main purpose to use it in the area of the South
Adriatic since it is designed for deep waters (up to 1000 m). This
area, during winters, is a site of deep water convection which is
monitored by OGS every year.
In October 2013 two new SLOCUM gliders, Galileo and Leonardo, designed
as shallow water instruments became part of the OGS fleet. They will
be mainly operated in the north and central Adriatic Sea.
A new Seaglider Kongsberg, named Marco, was purchased in September 2018
by the MAOS group and it will be used in the Mediterranean and in the Arctic sea.
The Seaglider sg554 Amerigo is deployed in the Southern Adriatic Sea along the Molfetta – Dubrovnik transect. The purpose of the experiment was to monitor the convection condition in the area of the South-Adriatic pit.

As part of South Adriatic monitoring annual program, a glider was deployed in the Southern Adriatic Sea from June 12 to July 2, 2020. The mission had the aim to assess the hydrographical characteristics present in June in the area of the South Adriatic pit after the winter deep convection.
This glider mission is part of the 2019-2020 Saildrone Atlantic to Mediterranean (ATL2MED) mission, in which two autonomous wind-powered vehicles sailed from Cabo Verde to Trieste, Italy, demonstrating how fit-for-purpose technology can be used to increase ocean observation.
During the mission Autonomous Surface and Subsurface Vehicles Work Together to Observe CO2 Exchange in the Adriatic Sea. The saildrones will attempt to join a OGS-led glider study in the Southern Adriatic close to the E2M3A station, providing surface observations to complement the sub-surface glider observations.

The Seaglider sg554 Amerigo was involved in the second part of MELMAS experiment (Monitoring of the Eastern Levantine with Mobile Autonomous Systems) in the East Mediterranean Sea, to monitor the area in front of Israeli coast. The project focused on the interaction between the open and coastal water masses and to study mesoscale feature present in the area and detached from the coastal current in The winter period.
The Slocum 403 Leonardo was deployed in the Southern Adriatic Sea along the Molfetta – Dubrovnik transect. The purpose of the experiment was to monitor the convection mechanism in the area.
The Seaglider sg661 Marco will be deployed in the Southern Adriatic Sea along the Molfetta – Dubrovnik transect. The purpose of the experiment was to monitor the pre-convection condition in the area.

The Slocum 402 Galileo was deployed in the Southern Adriatic Sea along the Molfetta – Dubrovnik transect. The purpose of the experiment was to monitor the pre-convection condition in the area.
The Slocum 403 Leonardo was deployed in the Southern Adriatic Sea along the Molfetta – Dubrovnik transect. The purpose of the experiment was to monitor the post-convection condition in the area.
The Seaglider sg554 Amerigo was involved in the CINEL (Circulation and water mass properties In the North-Eastern Levantine) experiment in the East Mediterranean. (For additional info http://nettuno.ogs.trieste.it/sire/cinel/info.html)
The Slocum glider unit403 Leonardo was operated in the Southern Adriatic Sea along the Molfetta - Dubrovnik transect. The purpose of the experiment was to monitor the pre-convection condition in the area.
The Seaglider Amerigo was involved in the CINEL (Circulation and water mass properties In the North-Eastern Levantine) experiment in the East Mediterranean. The glider was recovered South of Cyprus after a 48-day mission. For additional info (http://nettuno.ogs.trieste.it/sire/cinel/info.html)
The Slocum 403 Leonardo was deployed in the Southern Adriatic Sea. The purpose of the experiment was to study the post convection and the effect of the deep water formation in
the North Adriatic Sea. The glider covered part of the transect Molfetta – Dubrovnik and an area close of the Italian slope to inquire
about the dense water cascading. It was piloted down to almost 1000m deep in the area of the south-Adriatic pit.
The Slocum glider unit403 Leonardo was operated in the Southern Adriatic Sea. The purpose of the experiment was to study the pre-convection in the area. The glider covered the transect Molfetta – Dubrovnik. It was piloted to perform an Adriatic longitudinal transect in the area of the south-Adriatic pit.
The Slocum shallow glider unit403 Leonardo was operated in a mission within the North Adriatic Experiment 2015 in the Kvarner area. About 700 yos between 20 and 45 meters were performed collecting high frequency data of pressure, temperature, conductivity, oxygen, chlorophyll, CDOM and backscatter.
The Seaglider Amerigo was operated for 3 weeks in the Southern Adriatic Sea. The purpose of the experiment was to study the winter deep water convection in the area. The glider at first covered the transect Molfetta – Dubrovnik and then it was piloted to perform an Adriatic longitudinal transect, down to almost 1000m deep in the area of the South-Adriatic pit. At the end of the mission a butterfly sampling was performed close to the E2-M3A mooring.
The Seaglider Amerigo was deployed on May 15 and recovered on May 21, 2013. The area sampled during the mission covered the South Adriatic pit and the slope close to the Italian coast. In this experiment the OGS pilot team had the opportunity to trim the newly acquired glider fine-tuning the navigation parameters.
The Seaglider Amerigo was deployed in the Southern Adriatic Sea after the Teledyne tests. The mission last less then a day due to the WetLab fluorimeter connector leakage and some glider trim issues.
The French Slocum glider Tenuse, was operated to explore and study the dynamics of the southeastern Ligurian and Corsica Channel in summer 2010 as part of the LIDEX10 experiment, whose general objective was to improve the understanding of turbulent transport and dispersion in the ocean, more specifically to study the dispersion in a coastal frontal zone due to mixing by meso- and submesoscale structures
The slocum glider ‘Trieste 1’ was implied as part of an international project in the Levantine basin focused on a permanent cyclonic gyre south of Cyprus. The aim of the experiment was to produce an accurate 3-dimensional survey of this structure is supposed to create a physical barrier, which disconnects the “inside gyre” ecosystem dynamic to the “outside gyre” one. The mission last almost a month and was performed together with other 4 gliders: 3 deep gliders (sampling to 1000m) and an other shallow (sampling to 200m).gyre” one.

The slocum glider 'Trieste 1' was operated around the Vercelli seamount in the Tyrrhenian basin (Western Mediterranean Sea). The aim of the experiment was to study the effect on the hydrodynamics of the Vercelli seamount rising from the ocean seafloor (more then 1000 m) to 55 m below the surface.
The slocum glider ‘Trieste 1’ was deployed in the Ligurian Sea during the MREA08 Experiment. The main goal of the experiment was to collect oceanographic data to calibrate and validate the MREA (Marine Environmental Rapid Assessment) model system for environmental applications (i.e.: contaminant dispersal) in open sea and coastal areas. The glider experienced some technical problems (rudder damage, leakage) and performed only a limited number of profiles.

The MREA07 mission initially involves sampling along the transect between (25 nautical miles) the buoy SAMA-MAMBO (44°02’N - 9°50’E) and the buoy ODAS (43°47,36’N - 9°9,80’E) (25 nautical miles).
The experiment lasted 3 days and, the glider had to remain underwater for 5 hours.
