Cardich, J. ; Gutierrez, D. ; Romero, D. ; Pérez, A. ; Quipúzcoa, L. ; Marquina, R. ; Yupanqui, W. ; Solís, J. ; Carhuapoma, W. ; Sifeddine, A. ; Rathburn, A. | Inter Research | 2019-02-22T14:54:03ZWe studied 'living' (stained) benthic foraminifera in the upper border of the Peruvian oxygen minimum zone (OMZ) to determine the relationship between species' distribution and pore water and sediment geochemistry under oxygen deficiency. Superf[...]texto impreso
Salvatteci, R. ; Gutierrez, D. ; Sifeddine, A. ; Ortlieb, L. ; Druffel, E. ; Boussafir, M. ; Schneider, R. | Elsevier Doyma | 2019-02-22T14:55:02ZOxygen minimum zones (OMZ) have expanded in all tropical oceans during the last 50 years resulting in habitat contraction and considerable changes in marine biogeochemistry. However, for a better understanding of the OMZ dynamics under the curre[...]texto impreso
Salvatteci, R. ; Field, D. ; Sifeddine, A. ; Ortlieb, L. ; Ferreira, V. ; Baumgartner, T. ; Caquineau, S. ; Velazco, F. ; Reyss, J.-L. ; Sanchez-Cabeza, J.-A. ; Gutierrez, D. | Elsevier | 2020-06-10T18:12:14ZMarine laminated sediments in dysoxic areas of the ocean floor are an excellent archive for high-resolution climate reconstructions. While the existence of discontinuities produced by natural events, such as underwater landslides (slumps), stron[...]texto impreso
Salvatteci, R. ; Gutierrez, D. ; Field, D. ; Sifeddine, A. ; Ortlieb, L. ; Caquineau, S. ; Baumgartner, T. ; Ferreira, V. ; Bertrand, A. | Elsevier | 2019-07-04T16:59:35ZUpwelling of cold, nutrient-rich water from the oxygen minimum zone (OMZ) off Peru sustains the world's highest production of forage fish, mostly composed of anchovy (Engraulis ringens). However, the potential impacts of climate change on upwell[...]texto impreso
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 its relationship with pas[...]texto impreso
Multidecadal changes in marine subsurface oxygenation off central Peru during the last ca. 170 years
Cardich, J. ; Sifeddine, A. ; Salvatteci, R. ; Romero, D. ; Briceño-Zuluaga, F. ; Graco, M. ; Anculle, T. ; Almeida, C. ; Gutierrez, D. | Frontiers Media | 2019-08-08T15:23:45ZSubsurface water masses with permanent oxygen deficiency (oxygen minimum zones, OMZ) are typically associated with upwelling regions and exhibit a high sensitivity to climate variability. Over the last decade, several studies have reported a glo[...]texto impreso
Briceño-Zuluaga, F. ; Castagna, A. ; Rutllant, J. A. ; Flores-Aqueveque, V. ; Caquineau, S. ; Sifeddine, A. ; Velazco, F. ; Gutierrez, D. ; Cardich, J. | Elsevier | 2019-01-25T16:20:58ZDust 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 Imaging Spectroradiometer[...]texto impreso
Salvatteci, R. ; Gutierrez, D. ; Field, D. ; Sifeddine, A. ; Ortlieb, L. ; Bouloubassi, I. ; Boussafir, M. ; Boucher, H. ; Cetin, F. | Sage publications | 2020-06-10T18:11:37ZThe tropical Pacific ocean-atmosphere system influences global climate on interannual, decadal, as well as longer timescales. Given the uncertainties in the response of the tropical Pacific to increasing greenhouse gasses, it is important to ass[...]
