  • Attenuation of wind intensities exacerbates anoxic conditions leading to sulfur plume development off the coast of Peru 
    Flores Rafael, Edgart Elvis; Mendoza, Ursula; Callbeck, Cameron M.; Díaz, Rut; Aguirre-Velarde, Arturo; Böttcher, Michael E.; Merma Mora, Lander; Moreira, Manuel; Saldarriaga, Maritza S.; Silva-Filho, Emmanoel V.; Albuquerque, Ana L.; Pizarro-Koch, Matias; Graco, Michelle Ivette (PLoS, 2023)
    The release of vast quantities of sulfide from the sediment into the water column, known as a sulfidic event, has detrimental consequences on fish catches, including downstream effects on other linked element cycles. Despite ...
  • Electrochemical characterization of mangrove sediments: A proposal of new proxies for organic matter oxidation 
    Cebrián-Torrejón, G.; Perez Segovia, Alexander; Montoya, N.; Piquero-Cilla, J.; Saldarriaga, M.S.; Gutierrez Aguilar, Dimitri Alexey; Sanders, C.J.; Machado, W.; Doménech-Carbó, A. (Elsevier, 2019)
    The voltammetric response of microparticulate deposits resulting from solvent evaporation of ethanolic extracts of mangrove sediments in contact with aqueous acetate buffer is hereby described. Dated sediment cores sampled ...
  • Evidences and drivers of ocean deoxygenation off Peru over recent past decades 
    Espinoza-Morriberón, D.; Echevin, V.; Gutierrez Aguilar, Dimitri Alexey; Tam Málaga, Jorge; Graco, M.; Ledesma, J.; Colas, F. (Springer Nature, 2021)
    Deoxygenation is a major threat to the coastal ocean health as it impacts marine life and key biogeochemical cycles. Understanding its drivers is crucial in the thriving and highly exploited Peru upwelling system, where ...
  • 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 ...
