Happy to share this article from The NY Times on a recent interview where we discuss the MESO-Plastic experiment in Crete during POSEIDOMM project!

Microplastics Contamination Versus Inorganic Particles: Effects on the Dynamics of Marine Dissolved Organic Matter
This short communication paper highlights some findings of Amedeo’s Master thesis work on the comparison between inorganic and plastic particles in a laboratory microcosms setup. This paper follows previous work during the POSEIDOMM project.

It’s hard to explain “hard science” in simple words. We often tend to lock up in our labs in the pursuit of a mission. But if we are not able to communicate our science outside academia, aren’t we missing the track? Isn’t our mission losing some of its meaning?
We decided to try something new: “translate” one of POSEIDOMM papers in a paper that kids could read, and judge. It has been really challenging, but a great experience. The paper has been reviewed by super smart kids (Anna, Clara, Stephan, and Karina) full of curiosity and great questions.
It has not been easy, we tend to take most of the things we write for granted. I am really happy that finally the paper is out, and I have to thank a special person – my sister Teresa – for her drawings. She drew three pictures for this paper, and I think they are really beautiful!

Talk AI52A-06 – Enhanced production of dissolved and particulate organic matter in the presence of microplastics at the air-sea interface
Thanks to Raquel Somavilla Cabrillo for the pictures!
While there, it was also a great experience to co-lead the workshop in:
together with colleagues from the ASLO Outreach Subcommittee Elisha M Wood-Charlson from Lawrence Berkeley National Laboratory and Ngozi Margaret Oguguah from the Nigerian Institute for Oceanography and Marine Research.

Here’s the abstract:
“Microplastics are a major environmental challenge, being ubiquitous and persistent as to represent a new component in all marine environments. As any biogenic particle, microplastics provide surfaces for microbial growth and biofilm production, which largely consist of carbohydrates and proteins. Biofilms influence microbial activity and modify particle buoyancy, and therefore control the fate of microplastics at sea. In a simulated “plastic ocean”, three mesocosms containing oligotrophic seawater were amended with polystyrene microbeads and compared to three control mesocosms. The evolution of organic matter, microbial communities and nutrient concentrations was monitored over 12 days. The results indicated that microplastics increased the production of organic carbon and its aggregation into gel particulates. The observed increase of gel-like organics has implications on the marine biological pump as well as the transport of microplastics in the ocean.”

Frontiers in Marine Science – article published, introducing the Research Topic “Impacts of Marine Litter”

“Marine litter is an urgent environmental threat comprising primarily plastic debris. Yet, the global production of plastic is expected to double over the next decades, with envisaged severe impacts across ecosystems and societies. This editorial introduces to the Research Topic “Impacts of Marine Litter”, aiming at a better understanding of marine litter impacts from the ecological, ecotoxicological, economic, and social point of view. This Research Topic also aims at proposing new strategies for the prevention, mitigation and monitoring of marine litter. With its 13 published papers, the Research Topic provides new information on the environmental distribution (including sources and sinks) of marine litter across the globe, as well as on the impacts of plastics’ associated contaminants to marine micro and macro fauna. It also highlights constraints and priorities for conducting exposure experiments of marine wildlife to plastics, discusses regulation and policy measures for land waste management and litter disposal at sea, and identifies remaining knowledge gaps which should be the focus of future interdisciplinary research and policy interventions.”

Happy to share with you! Last week we were at EGU General Assembly 2019 to present POSEIDOMM results. We had a poster in the session “Plastic in the environment: observing and explaining where it comes from and where it goes”
on display on Monday, 8th of April. Our poster presentation was titled:
“Microplastics Influence Carbon Dynamics of Marine Surface Waters”
and you can find the abstract here.
A highlight of the General Assembly was undoubtedly the Science and Society Dialogue of Geoscientists with Ilaria Capua and Mario Monti, focusing on Science and Politics.
“The dialogue between scientists, institutions, policymakers and the general public is widely recognised as an essential step towards a fair and sustainable society. Nowadays, more than ever in human history, international cooperation is an essential requirement for protecting the planet, advancing science and ensuring an equitable development of the global economy.”

It’s back! UN Environment and the Open University have created a Massive Open Online Course (MOOC) on Marine Litter. It is part of Clean Seas and contributes to the goals of the Global Partnership on Marine Litter. Register here! Starts in April. Available in multiple languages!
