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

However, the potential impacts of climate change on upwell[...]texto impreso
Pérez, A. ; Gutierrez, D. ; Saldarriaga, M. S. ; Sanders, C. J. | Springer Verlag | 2019-01-25T16:20:57ZA 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 that during the dry se[...]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
