Sedimentation rates in the Corumbataí River basin, Brazil, derived from 210Pb measurements
Activity profiles of excess 210Pb measured in four sediment cores from the Corumbataí River basin, São Paulo State, Brazil, provided an opportunity to evaluate sedimentation rates that are helpful for defining appropriate ...
Urban activity and mercury contamination in estuarine and marine sediments (Southern Brazil)
The distribution of mercury in sediments of the Patos Lagoon estuary and nearby coastal marine deposits has been investigated for the period 1998–2008. Polluted urban soils and coastal reclamation fills are the principal ...
Spatial and temporal patterns in reef sediment accumulation and composition, southwestern insular shelf of Puerto Rico
(Caribbean Journal of Science, Vol. 45, No. 2-3, 138-150, 2009, 2014)
Sediment origin and budget in Sepetiba Bay (Brazil): an approach based on multielemental analysis
(Springer Berlin / Heidelberg, 1997)
Sediment origin and transport were determined in a shallow 447 km2 coastal lagoon in Brazil, using the distribution of major elements in bottom and suspended sediments. Applying multivariate analysis, the sum of normalized ...
Tidally driven sulfidic conditions in Peruvian mangrove sediments
The seasonal influence of tidal regimes on sulfidic conditions was studied in intertidal environments from a mangrove estuary in Northern Peru. Along two sampling stations, creek water and sediment cores were collected ...
Late Holocene fluctuations of Quelccaya Ice Cap, Peru, registered by nearby lake sediments
Records of clastic sediment from lakes that receive glacial meltwater provide a means for inferring past glacial fluctuations. However, increased clastic sedimentation has been interpreted to indicate both glacial advance ...
Integrated sediment quality assessment in Paranagua Estuarine System, Southern Brazil
(Academic Press Inc. Elsevier B.V., 2009-10-01)
Sediment quality from Paranagua Estuarine System (PES), a highly important port and ecological zone, was evaluated by assessing three lines of evidence: (1) sediment physical-chemical characteristics; (2) sediment toxicity ...
