| Instrumentation Viewpoint
The Spanish Committee of Glider Operators (CEOG) is a strategic network with the main objective of contributing to the improve- ment in the national management and coordination of the cur- rent distributed (and unconnected) fleet of ocean-observing ve- hicles (underwater gliders and Uncrewed Surface Vehicles, USV) for scientific-technical purposes, operated by the main national entities in this field (Spanish Institute of Oceanography -IEO- of the Spanish National Research Council -CSIC-, AZTI, the University of Las Palmas de Gran Canaria -ULPGC-, the ICTS-SOCIB and the ICTS-PLOCAN), for a more organized, efficient and value-added management in service to the national community, while facilitat- ing and promoting relevant Spanish involvement in decision-mak- ing related to infrastructures, programs and other strategic initia- tives of European and/or international nature in this matter.
