About me

I obtained my Bachelor in Environmental Sciences at the Universitat Autònoma de Barcelona (UAB), Spain, in 2014 and became more specialized in marine sciences by completing the Master in Oceanography at the Universitat de Barcelona and Universitat Politècnica de Catalunya in 2015.

As an environmental scientist, I am interested in understanding processes in marine environments and how anthropogenic activities alter them. With this in mind, I undertook a PhD in Environmental Sciences and Technology at my alma mater, UAB, studying the physical and biogeochemical impacts of bottom trawling on the seafloor of the Western Mediterranean margin, which I completed in 2020.

I am now working as a post-doctoral researcher on a global database of organic carbon in marine sediments, Modern Ocean Sediment Archive and Inventory of Carbon (MOSAIC), to understand the factors that affect the distribution of organic carbon and its composition, and the influence of anthropogenic activities.

[12/04/2023] We are disturbing marine sediments through a myriad of ways, even when it comes to providing internet! Ever wondered what is the impact of the global subsea telecommunications network on sedimentary organic carbon stocks? New paper out in Nature Communications where we discuss this further.

[24/02/2023] I have been granted an Open Research Data-Contribute Project: Application Programming Interface for the Modern Ocean Sedimentary Inventory and Archive of Carbon database (API-MOSAIC). With this grant, we will further expand and update the accessibility to the MOSAIC database. New website and API are coming to you this 2023!

[09/11/2022] I was invited to give a talk for the Environmental Research Change Group seminar series, at St. Andrews University. I’ll be presenting a compilation of my recent research (all unpublished), so if you are in St. Andrews, don’t miss it!

[02/11/2022] Aline Wildberger successfully defended her Master thesis: “Tackling geomorphological heterogeneity: a comparison of predictors and modelling approaches to assess the distribution of sedimentary organic carbon in submarine canyons”. We are now working hard to convert it into a manuscript. Stay tuned!

[26/10/2022] New paper out on the sediment fluxes and its composition in Palamós Canyon (NW Mediterranean) during winter storms and trawling activities. For a quick summary, check out the Twitter thread.

Media coverage and outreach

[09/07/2021] Interviewed by AGU science news journal EOS highlighting how more studies on the impacts of bottom trawling on sediment biogeochemistry are needed to extrapolate the impacts of this activity at a global scale.

[24/01/2021] Interviewed by Costa Rican newspaper on how bottom trawling depletes organic matter on the deep seafloor, relevant to this country given the recent discussion on lifting the ban of this fishing technique.

[04/01/2021] Nature Research Highlight on a recent paper, which emphasizes that seasonal trawling closures are insufficient to restore sedimentary organic matter on the seafloor.

[30/12/2020] Public appearance on local Catalan news TV3 explaining how the impacts of bottom trawling can jeopardize the seafloor if proper management techniques are not applied.

[25/04/2020] Short video and documentary on how the collaboration between fishermen and scientists can mitigate the impacts of bottom trawling on the seafloor. Sponsored by AGU’s Centennial Grant.
