NASA’s strategic goal to “study Earth from space to advance scientific understanding and meet societal needs”, prompted “GAVDOS”, a joint NASA-EU R&D; project that over the past ten years evolved into a regional network of tide gauges monitored with continuous GPS in Western Crete, Greece. Unique in the area, it collects continuous precise monitoring of sea level and environmental parameters. Its data and our analysis products help answer strategic questions about Earth system changes, their cause and how Earth responds to these, NASA research objectives 2, 4, 5, and 7. While e-MACnet offers a wide range of existing, in-place hardware and facilities, we are continuously expanding, improving services, products, quality-control and near-real-time information dissemination. This proposal requests NASA’s support to: extend operations and maintenance of the facility; continue the combination, analysis and interpretation of all radar altimeter data in the area; prepare for the upcoming Jason-2 launch and calibration phase; and integrate our facilities with IOC’s Tsunami Warning System network (ICG/NEMTWS). The proposal builds upon the original GAVDOS project’s legacy. It relies on collaborations with other European groups, e.g. the French group at the western Mediterranean calibration facility in Corsica, and contributes to other projects, e.g. GOOS, GGOS, MedGLOSS, ICG/NEMTWS, ESEAS, etc. We support a vital aspect of NASA’s ocean science program: the collection of in situ data in support of satellite missions and contribute to regional environmental monitoring of a poorly instrumented area. The proposed offshore buoy will extend the network utility and contribute to the tsunami hazard mitigation goal and coastal science for the region. Unlike other calibration sites, our network, situated under a cross-over of two tracks, i.e. two calibrations per repeat cycle, and with a third site now (Kasteli), provides a total of three observations per repeat cycle.
