MONDO Project (Monitoring by Ocean Drifters) is a pioneer initiative from ENI Oil do Brasil and PROOCEANO that aims to provide unrestricted access oceanographic data to subsidize not only the companies operational goals but also the scientific community.
Within 2 months – during the Sagatiba and Belmonte 2 wells drilling operations –, 40 drifters will be deployed. Throughout the project webpage, the drifters may be followed in real-time and the transmitted data may be downloaded. The drifters are “holey-sock” type, composed by a surface floater, a tether and a submerged drogue, following the design criteria proposed by Sybrandy and Niiler (1991). The drogue length is 6.44 m, centered at 15 m deep, in order to represent the first 20 m current information. The drifter position is obtained by GPS (Global Positioning System) and a temperature sensor is installed inside the surface floater. Sea surface temperature data will be collected every hour and a GPS position every 3 synoptic hour (00:00, 03:00, …, 18:00, 21:00), with a nominal resolution of 7 m. Data transmission is accomplished by the IRIDIUM satellites every hour. Two different deployments are planned:
Following the methodology proposed by Molinari & Kirwan (1975), turbulent parameters of the flow may be estimated by the relative displacements between the simultaneously deployed drifters. REFERENCE

[16/01/08] Drifter #40 recovered. In 18 Dec. 2007 drifter #40 was found by fisherman at Paranaguá Bay (PR). The buoy was recovered and is at PROOCEANO´s office now. [13/11/07] The last two drifters (#39 and #40)were deployed. The drifter #40 was deployed undrogued in order to study the influence of the wind over the drift. See also photos, videos and animations of the drifters. [12/11/07] First international MONDO drifter. Drifter #8 passed the borders of Brazil and now drifts at Uruguayan waters. Follow up! [01/11/07] Deployment of 5 buoys array - Group D. The deployment of group D (drifters 27 to 31) was performed with a new methodology. The drifters were deployed at the vertices and at the center of a square whose sides have 20km length. [22/10/07] Data download is already avaiable The drifters data download is now avaiable. Links can be found in the Trajectories tab. [02/10/07] Held the first deployment of 5 drifters On October 2 was held the first simultaneous deployment of 5 drifters of the MONDO Project. [01/10/07] Data download The data sent by MONDO Project's drifters are experiencing a first consistency test and will be avaiable for download on October 15. Registration is now available for data access. [20/09/07] Deployed MONDO PROJECT'S first drifter. On September 20, at 2:30 p.m., was deployed the first drifter of the MONDO Project. The deployment dates will be marked on the calendar alongside. Keep track!
