List of microplastic and marine litter samples collected from the sediment and water and deposited at CURE
AI summary Read the abstract
This dataset inventories sediment and water samples collected for microplastic and marine litter analysis across a wide depth range (5–4,277 m) during the Falkor (too) research cruise in 2025, using ROV and CTD methods across 22 dive operations. The deep-sea sampling coverage provides critical data on microplastic distribution in understudied abyssal environments where plastic debris ultimately accumulates.
This dataset presents the inventory of sediment and water samples collected for the analysis of marine litter and microplastics during the Falkor (too) research cruise (FKT250812). The dataset tracks samples across 22 different dive operations (Dives 827 to 854), utilizing two primary deployment strategies. Samples were acquired using the ROV SuBastian (benthic/sediment) and CTD Rosette bottles (pelagic/water column) between August 23 and September 17, 2025, covering a wide bathymetric range from shallow waters (5 m) to abyssal depths (4,277 m). Pelagic Sampling (Carousel/CTD) add to 11 water collection events using Niskin bottles, yielding a total of 139 water samples primarily for water column analysis. Benthic/Deep-Sea Sampling (ROV SuBastian) comprises 120 targeted collection events utilizing multiple methods, including Push-core(18 sediment samples), Niskin bottles (42 samples for near-bottom water), Macrolitter (30 collection events for anthropogenic debris) and Biota (29 sampling events). These materials are curated and deposited at the Centro Universitario Regional del Este (CURE), Universidad de la República (UdelaR), Uruguay. This collection constitutes Deliverable #13 under the Joint Project Agreement (JPA) between UdelaR and the Schmidt Ocean Institute (SOI).

Accurate sampling of undisturbed top sediment from grab sampler collected using aluminum tube and stainless-steel containers for shallow and deep-sea applications
AI summary Read the abstract
Researchers developed a sediment sampling protocol using a Kinoshita-type grab sampler with stainless steel containers and aluminum tubes to collect microplastics and macroplastics from 133 marine sediment samples at depths of 20-800 m during the GB24 geological survey cruise, minimizing contamination while maintaining sample integrity.
Falling into the darkness – microplastics sinking fluxes in the deep sea
AI summary Read the abstract
Researchers deployed a sediment trap at 230 metres depth on the Condor seamount in the Azores for 12 months, collecting 18 sequential samples to quantify seasonal patterns in microplastic sinking fluxes and investigate the mechanisms by which floating microplastics are transported to the deep sea.
Abundance of microplastic in surface sediment during POLARSTERN cruise PS93.2
AI summary Read the abstract
This dataset provides the abundance of microplastics in surface sediment samples collected during the POLARSTERN cruise PS93.2 in the Arctic, supplementing Bergmann et al. (2017), which reported high quantities of microplastic in Arctic deep-sea sediments from the HAUSGARTEN Observatory. The data supports spatial analysis of microplastic contamination in Arctic deep-sea sediment environments.
Distributions of microplastics and larger anthropogenic debris in Norfolk Canyon, Baltimore Canyon, and the adjacent continental slope (Western North Atlantic Margin, U.S.A.)
AI summary Read the abstract
Researchers documented microplastics and larger anthropogenic debris in sediment cores and ROV samples from Norfolk Canyon and Baltimore Canyon on the U.S. Atlantic continental slope, finding debris accumulated at depth likely through turbidity currents and downslope transport.
