Three main drainage basins debouch into the bay, providing a mean freshwater discharge of 200 m3/s (prior to 1985), or less than 1% of the spring tidal discharge through the bay mouth. Based on the result of several sedimentological studies performed in the 1970's, five surface sedimentary facies were identified inside the bay, namely i) transgressive siliciclastic marine sand facies; ii) transgressive bay sand-mud facies; iii) a transgressive carbonate marine sand facies; iv) regressive bay-mud facies, and v) regressive fluvial sand facies. The spatial distribution of these facies would follow, somewhat closely, the hydrodynamic-energy distribution inside the bay. Seismic profiles along the bay bottom indicate the existence of several paleochannels, 5-10 m deep, blanketed at least by three different sedimentary units. The topmost sedimentary unit, 5-20 m thick, appears to be associated with the regressive bay-mud facies, and assuming that it was laid down within the last 5000 years, sedimentation rates for the central and northeastern part of the bay would average at 2,4 mm/y.Submitted by Texeira Ana (atanateixeira@gmail.com) on 2012-08-01T12:59:54Z No. of bitstreams: 1 LESSA, GUILHERME C.(2).pdf: 1651726 bytes, checksum: 295960396b0a97d2112835122a8588c7 (MD5)Made available in DSpace on 2012-08-01T12:59:54Z (GMT).
