Hadal trenches are considered to act as depocenters for organic material, although pathways for the material transport and deposition rates are poorly constrained. Here we assess focusing, deposition and accumulation of material and organic carbon in four hadal trench systems underlying different surface ocean productivities; the eutrophic Atacama and Kuril-Kamchatka trenches, the mesotrophic Kermadec trench and the oligotrophic Mariana Trench.

(Forest Sciences Centre of Catalonia . Laboratory of Functional Ecology and Global Change)
Grasslands are one of the major sinks of terrestrial soil organic carbon (SOC). Understanding how environmental and management factors drive SOC is challenging because they are scale-dependent, with large-scale drivers affecting SOC both directly and through drivers working at small scales. [...]

19 p, 8.9 MB Global nutrient cycling by commercially-targeted marine fish / Le Mézo, Priscilla K. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Guiet, Jérôme (University of California. Atmospheric and Oceanic Sciences) ; Scherrer, Kim J. N. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Bianchi, Daniele (University of California. Department of Atmospheric and Oceanic Sciences) ; Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Throughout the course of their lives fish ingest food containing essential elements, including nitrogen (N), phosphorus (P) and iron (Fe). Some of these elements are retained in the fish body to build new biomass, which acts as a stored reservoir of nutrients, while the rest is excreted or egested, providing a recycling flux to water.

15 p, 1.2 MB Quantitative Link Between Sedimentary Chlorin and Sea-Surface Chlorophyll-a / Raja, Maria (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Rosell Melé, Antoni (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Primary productivity in the ocean plays a major role in the global carbon cycle. To estimate its changes through geological time, different sedimentary proxies are used. However, the relative weights of the various processes driving the sedimentary accumulation of organic matter are not fully constrained or represent the flux of specific algal classes. [...]

23 p, 7.3 MB Assessing the role of high-frequency winds and sea ice loss on arctic phytoplankton blooms in an ice-ocean-biogeochemical model / Castro de la Guardia, Laura (University of Alberta. Department of Earth and Atmospheric Sciences) ; Garcia-Quintana, Yarisbel (University of Alberta. Department of Earth and Atmospheric Sciences) ; Claret Cortes, Mariona (McGill University. Department of Earth and Planetary Sciences) ; Hu, Xianmin (University of Alberta. Department of Earth and Atmospheric Sciences) ; Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Myers, Paul (University of Alberta. Department of Earth and Atmospheric Sciences)
The long-term trend of increasing phytoplankton net primary production (NPP) in the Arctic correlates with increasing light penetration due to sea ice loss. However, recent studies suggest that enhanced stormy wind mixing may also play a significant role enhancing NPP. [...]

14 p, 4.3 MB Organic matter contents and degradation in a highly trawled area during fresh particle inputs (Gulf of Castellammare, southwestern Mediterranean) / Paradis, Sarah (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Pusceddu, Antonio (Università degli Studi di Cagliari.

Laboratorio di Ecologia Sperimentale e Acquacoltura (Italy)) ; Iacono, Claudio Lo (University of Southampton Waterfront Campus. National Oceanography Centre (UK))
Bottom trawling in the deep sea is one of the main drivers of sediment resuspension, eroding the seafloor and altering the content and composition of sedimentary organic matter (OM). The physical and biogeochemical impacts of bottom trawling were studied on the continental slope of the Gulf of Castellammare, Sicily (southwestern Mediterranean), through the analysis of two triplicate sediment cores collected at trawled and untrawled sites (<span classCombining double low line"inline-formula">ĝ'1/4550</span> m water depth) during the summer of 2016.
