COCONet

The purpose of COCOnet was to:

• Provide details on the tectonics of the entire Caribbean region.
• Enhance atmospheric observations that can be used for testing and validation of climate and weather models.
• Improve the analysis of local geodetic (the science of planetary measurement) measurements by providing access to an integrated backbone electronic network of reference stations.
• Increase our ability to model and predict the natural hazards (earthquakes, hurricanes and so on) in the region.

To accomplish the function of climate modeling and other objectives., the network also had tide gauges in Mexico, Jamaica, the Dominican Republic, and Panama.^[5] In terms of atmospheric measurements and related goals, the COCOnet stations were able to assist the Constellation Observing System for Meteorology, Ionosphere, and Climate of the University Corporation for Atmospheric Research (UCAR/COSMIC) as it created continuous estimates of precipitable water vapor.^[5]

A notable station is the station on the isolated Isla del Coco (Cocos Island), Costa Rica, in that it is the only GPS station continuously tracking the Cocos Plate, as it passes underneath the Caribbean Plate, at a rate of 78 millimeters (mm) per year.^[4][6] Because the island is the only land mass of the Cocos Plate that is above sea level, this was the only place where Cocos Plate motion observations could be measured in this GPS network. A continuous GPS station was built and instrumented on the island in May 2011. Data from the station show a steady motion of the island at a speed of 90.9±1.5mm/yr. or approximately 90 millimeters a year.

COCOnet had held for workshops. The meetings can help to understand the history of the project:

The original COCONet project proposal was covered in three workshops:

• The first one was planned to be held in San Juan, Puerto Rico (February 3–4, 2011)
• The second meeting was to be held in Port-of-Spain, Trinidad, Republic of Trinidad & Tobago (June 28–29, 2011) with one of several goals being for Caribbean network operators to address the specifics of choosing existing and new stations.
• The third COCONet workshop focused primarily on longer-term operations and maintenance for GPS stations installed in the Caribbean, and related issues.^[8]

The following were the data centers:^[9]

• Servicio Geólogico Colombiano (SGC) (Columbian Geological Survey) - Regional Data Center
• Caribbean Institute for Meteorology & Hydrology (CIMH), Barbados - Regional Data Center
• Instituto Nicaragüense de Estudios Territoriales (INETER) - Regional Data Center

The last publications and workshops of COCOnet were the following:

The last workshop was COCONet - Results, Sustainability, and Capacity Building, which had been held May 3–5, 2016 in Punta Cana, Dominican Republic.^[5]
