An attempt to use color as a tool for high resolution correlations between estuarine sedimentary cores from Algarve (Portugal)

摘要

Nowadays, paleoenvironmental and climatological researches focus on studying shorttermclimatic changes and one of the more sensitive environments for recording thoseshort-term climatic variations are the high sedimentation rate of coastal regions. Accordingly,4 estuaries from the Algarve region, south of Portugal, have been coredin order to study sedimentary and climatic variations during recent times (c.a. 5000yrs). For this purpose, we applied sampling and analytical techniques from deep-seastudies, allowing the acquirement of almost continuous data profiles, as the color dataobtained with the spectrophotometer Colortron.
