Glider Mission History

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.


12 June - 02 July 2020 20 days Convex 20 Seaglider Amerigo configuration Scientific - information Technical - information

Convex 20 - 2020 June

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.
