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.

Convex 16 - 2016 April

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.

PreConvex 16 - 2015 November

The Slocum 403 Leonardo was successfully operated for 10 days (from November 20 to December 1 2015) 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, down to almost 1000m deep in the area of the south-Adriatic pit.

Quarnero 2015 - 2015 February

The Slocum glider Leonardo was operated in a 4-day 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. 24-27 February 2015.

Convex 14 - 2014 February

The Seaglider Amerigo was successfully operated for 3 weeks (from February 15 to March 6 2014) 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.

Coconet - 2013 May

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.

Convex 13 - 2013 March

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.
