Journal ArticleDOI
Plastic debris in the open ocean
Andrés Cózar,Fidel Echevarría,J. Ignacio González-Gordillo,Xabier Irigoien,Bárbara Úbeda,Santiago Hernández-León,Alvaro T. Palma,Sandra Navarro,Juan García-de-Lomas,Andrea Ruiz,María L. Fernández-de-Puelles,Carlos M. Duarte +11 more
TL;DR: Using data from the Malaspina 2010 circumnavigation, regional surveys, and previously published reports, this work shows a worldwide distribution of plastic on the surface of the open ocean, mostly accumulating in the convergence zones of each of the five subtropical gyres with comparable density.

Journal ArticleDOI
Large mesopelagic fishes biomass and trophic efficiency in the open ocean
Xabier Irigoien,Thor A. Klevjer,Anders Røstad,Udane Martinez,Guillermo Boyra,José Luis Acuña,Antonio Bode,Fidel Echevarría,J.I. González-Gordillo,Santiago Hernández-León,Susana Agustí,Susana Agustí,Dag L. Aksnes,Carlos M. Duarte,Carlos M. Duarte,Stein Kaartvedt +15 more
TL;DR: Modelling and a sensitivity analysis of the acoustic observations from the Malaspina 2010 Circumnavigation Expedition show that the previous estimate of mesopelagic fishes biomass needs to be revised to at least one order of magnitude higher, and there is a close relationship between the open ocean fishes biomass and primary production.
Journal ArticleDOI
The Arctic Ocean as a dead end for floating plastics in the North Atlantic branch of the Thermohaline Circulation
Andrés Cózar,Elisa Martí,Carlos M. Duarte,Carlos M. Duarte,Juan García-de-Lomas,Erik van Sebille,Erik van Sebille,Thomas J. Ballatore,Víctor M. Eguíluz,J. Ignacio González-Gordillo,Maria Luiza Pedrotti,Fidel Echevarría,Romain Troublé,Xabier Irigoien +13 more
TL;DR: The seafloor beneath this Arctic sector is hypothesized as an important sink of plastic debris given the limited surface transport of the plastic that accumulated here and the mechanisms acting for the downward transport, which would be a dead end for this plastic conveyor belt.
Journal ArticleDOI
Mesoscale vertical motion and the size structure of phytoplankton in the ocean
Jaime Rodríguez,Joaquín Tintoré,John T. Allen,Jose Ma Blanco,Damià Gomis,Andreas Reul,Javier Ruiz,Valeriano Rodríguez,Fidel Echevarría,Francisco Jiménez-Gómez,Francisco Jiménez-Gómez +10 more
TL;DR: An empirical model relates the magnitude of mesoscale vertical motion to the slope of the size–abundance spectrum of phytoplankton in a frontal ecosystem and indicates that the relative proportion of large cells increases with the magnitude of the upward velocity.
