RDSEA supports new tide gauge installations in Costa Rica. The five-star Los Suenos Marina, Herradura, Puntarenas, Costa Rica now has daily tidal data available for its’ users and the nearby community. Original specifications for the system were for routine monitoring, with future upgrade to a tsunami warning station planned. Campbell Scientific, Centro Caribe and J.S. Marine and Environmental Services, St Petersburg, FL, were responsible for the installation in the field using an AQUATRAK Liquid Level Measuring System integrated with a Campbell Scientific CR-1000 data logger/controller. Data transmission is via NOAA’s GOES Satellite Service. Data will also be received and managed by the Univ. of Hawaii Sea Level Center (UHSLC). The UHSLC collaborates with agencies within host countries in the installation and maintenance of a global network of tide gauge stations, which meet standards that range in resolution from tsunami warning to global sea level rise.
