  • Holocene paleohydrology of Quistococha Lake (Peru) in the upper Amazon Basin: Influence on carbon accumulation 
    Aniceto, Keila; Moreira-Turcq, Patricia; Cordeiro, Renato C.; Fraizy, Pascal; Quintana, Isabel; Turcq, Bruno (Elsevier, 2014)
    In order to study the impact of hydrological changes of the Amazon River on sedimentation process and organic matter (OM) accumulation, in an Amazonian floodplain lake during the Holocene, three sediment cores were collected ...
  • Hydrological controls on the biogeochemical dynamics in a Peruvian mangrove forest 
    Perez Segovia, Alexander; Gutierrez Aguilar, Dimitri Alexey; Saldarriaga, M. S.; Sanders, C. J. (Springer, 2017)
    A tropical mangrove forest in Northern Peru was studied to determine if physical and biogeochemical characteristics of creek water and subtidal sediments are related to the seasonal hydrological regimes. The results showed ...
  • Late Holocene fluctuations of Quelccaya Ice Cap, Peru, registered by nearby lake sediments 
    Stroup, J.S.; Kelly, M.A.; Lowell, T.V.; Smith, C.A.; Beal, S.A.; Landis, J.D.; Tapia, P.M. (Wiley, 2015)
    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 ...
  • Mercury accumulation rates in Caco Lake, NE Brazil during the past 20.000 years 
    de Lacerda, L. D.; Turcq, B.; Sifeddine, A.; Cordeiro, R. C. (Elsevier, 2017)
    Total Hg, TC, TN, goethite and siderite distributions in sediment cores from two locations across Caco) Lake (Brazil) identified paleoclimate factors that had affected the Hg deposition in this shallow tropical lake and ...
  • Paracas dust storms: Sources, trajectories and associated meteorological conditions 
    Briceno-Zuluaga, F.; Castagna, A.; Rutllant, J. A.; Flores-Aqueveque, V.; Caquineau, S.; Sifeddine, A.; Velazco, F.; Gutierrez Aguilar, Dimitri Alexey; Cardich Salazar, Jorge Aquiles (Elsevier, 2017)
    Dust storms that develop along the Pisco-Ica desert in Southern Peru, locally known as "Paracas" winds have ecological, health and economic repercussions. Here we identify dust sources through MODIS (Moderate Resolution ...
