The Spanish Institute of Oceanography Observing System around N and NW Iberia

In the late 80's, the Spanish Institute of Oceanography (IEO) began some ambitious programs of monitoring around the Iberian Peninsula. The coastal observing system core structure was the Radiales program, a series of transects nearby most coastal IEO laboratories where a minimum set of hydrographical, chemical and biological parameters is sampled monthly. The sections are designed to be completed in one-day journeys so the system is supported by quite small vessels, mainly covering the continental shelf with the noteworthy exception of the Santander Section, where the proximity of the shelf-break allows sampling deep waters monthly. During the last 20 years the program has supported many specific scientific research projects and has created a detailed description of seasonal to interannual variability in the coastal ecosystem that serves as a baseline to explore long-term changes or trends...Versión de auto
