Microplastic abundance in surface water samples during the cruise SO296-1 over the shelf of eastern Pacific
Summary
This dataset records microplastic concentrations collected from surface waters along the eastern Pacific shelf between the US and Chile during a research cruise. Providing baseline data from this under-sampled ocean region helps researchers understand how microplastics are distributed in the Pacific and supports modelling of their long-range transport.
During the cruise SO296-1 on board of the German RV SONNE, we collected samples from the ship pumping system, connected to a filtration unit for microplastic analyses along the shelf of the eastern Pacific between Port Hueneme (USA) and Talcahuano (Chile). On the 0.7 µm GF filters between 300 and 560 L of surface water was filtered. The microplastic detection was carried out in the IOW laboratory using binocular microscope and the FTIR (LUMOS II, Bruker Optik GmbH, Germany). This data is reported together with surface temperature and salinity based on the continuous registration by thermosalinograph (https://doi.org/10.1594/PANGAEA.968975). Additional details about the cruise can be found in the cruise report (https://doi.org/10.48433/cr_so296_1), additional surface environmental data can be found at https://doi.org/10.1594/PANGAEA.988025.

Microplastic abundance, distribution and composition in the mid-west Pacific Ocean
Researchers surveyed microplastic abundance, distribution, and composition across the mid-west Pacific Ocean, an area with previously limited data, finding widespread contamination across sampled stations. The dominant particle types were fibers and fragments, with concentrations varying by location and depth.
Dataset behind review manuscript "Macrolitter and microplastics along the East Pacific coasts – a homemade problem needing local solutions"
This dataset compiles published data on macro-litter and microplastic abundance, distribution, composition, and sources along the East Pacific coast from Alaska to Chile. The dataset supports a review of plastic pollution in this region and identifies local human activities as the dominant source, reinforcing the need for local management solutions.
Microplastics in the Northwestern Pacific: Abundance, distribution, and characteristics
Microplastics were sampled at 18 stations across the Northwestern Pacific Ocean surface using manta trawls, finding widespread but heterogeneous distribution, with higher concentrations in areas near shipping lanes and ocean current convergence zones and polyethylene and polypropylene as dominant polymers. The study provides open-ocean baseline data for the Northwestern Pacific, a region historically underrepresented in microplastic monitoring.
Tracking microplastics and the associated ecological risk in the southwestern Pacific Ocean
Researchers assessed microplastic abundance and composition along an approximately 1,000 km oceanographic transect of the southwestern Pacific coast of Chile, sampling at six river mouths and characterizing the ecological risk associated with plastic pollution entering coastal marine environments.
Microplastic pollution in seawater and marine organisms across the Tropical Eastern Pacific and Galápagos
Researchers collected water samples across a 4,000 km Pacific Ocean trajectory and found microplastics throughout, along with microplastics in fish, squid, and shrimp caught for human consumption along the coast. The study confirms widespread plastic contamination across the Tropical Eastern Pacific, including in seafood species eaten by humans.
