North Sea Summer Survey 2024, RV ATAIR
AI summary Read the abstract
Researchers conducted a North Sea summer survey aboard the RV ATAIR in 2024, investigating the physical and chemical state of the sea across a standard station network to observe major inflow and outflow patterns, with microplastic sampling among the measurements.
The scientific cruise 067I033-1 with the Research Vessel (RV) ATAIR aimed to investigate the physical and chemical state of the North Sea in summer 2024. The focus was on surveying a large-scale network of standard station locations at specific latitudes in order to observe the major inflow and outflow conditions into and out of the North Sea. The overall aim was to obtain suitable physical oceanographic data that serves to further extend already existing time series on the hydrographic properties of the North Sea’s water column. Biological data obtained on selected stations with respect to chlorophyll-a and phytoplankton will be used to validate and compare satellite data. Chemical measurements address the carbon system of the North Sea and also serve to assess the concentrations of certain trace metals including mercury and its species as well as microplastic concentrations.

North Sea Plastics II: Fate and impact of river-borne microplastics and their chemical additives in the North Sea Cruise No. AL596, 26 June – 02 July 2023, Kiel, DE – Kiel, DE

Researchers conducted the North Sea Plastics II cruise (AL596, June-July 2023) as the summer counterpart to the winter AL586 cruise, both part of the H2020 LABPLAS project, to assess seasonal differences in the transport and fate of river-derived small micro- and nanoplastics and their chemical additives in the coastal southern North Sea. Together, the two cruises provide a framework for understanding how seasonal riverine discharge patterns influence the delivery, distribution, and chemical contamination burden of microplastics in the North Sea.

AI summary Read the abstract
Researchers measured microplastic concentrations at the sea surface and in sediments across the southern North Sea and northwestern Europe, finding highly variable but widespread contamination. Sediments contained far higher concentrations than surface waters, confirming that the seafloor acts as a major sink for microplastic pollution.
