Long-TermOceanographicMeasurements

  • PIRATA Program (Pilot Research Moored Array in the Tropical Atlantic)

    • About 16 buoys in the equatorial region

  • In the southeastern Atlantic portion

    • Long time series only for sea level

    • One long time series for sea temperature (not collected for scientific purposes)


  • Temperature of water used for cooling machinery of the Companhia Nacional de Álcalis, Arraial do Cabo, RJ

    • - Oldeststation still in activity – Cananéia/SP since 1954

    • - Longestcontinuous series – Cananéia/SP from 1954 to 1995

    • - Improvementdata quality → Progam GLOSS-Brasil


    - Companhia Nacional de Álcalis, Arraial do Cabo, RJCurrently, 17 tidestations, 11 fromotherinstitutionsthantheBrazilianNavy.

    • From 1955 to 2007 → analogicalgauge

    • From 2007 tonow → radar basedtechnology

    • Conclusions Companhia Nacional de Álcalis, Arraial do Cabo, RJ

    • Very few long-time oceanographic series in the Western South Atlantic, turning unfeasible comparisons with climatological results from models.

    • Some new attempts to fill this gap, but still in early stages.

    • Main problems related to logistics, depredation and maintenance.

    • Results can be used to indicate anomalous events, which could be explained in other spatial scales, by numerical modeling.
