We focus on the network that is operated by the Mid Atlantic Regional Association Coastal Ocean Observing System (MARACOOS). The network currently consists of 38 radars making real-time measurements of the surface currents over the continental shelf for a variety of applications including

Deriving erosion thresholds of freshly deposited cohesive sediments from the port of Hamburg using a closed microcosm system Front. Marine Sci. (IF 3.7) Pub Date : 2024-05-06 M. Witt, J. Patzke, E. Nehlsen, P. Fröhle
The quantification of the erodibility of cohesive sediments is fundamental for an advanced understanding of estuarine sediment transport processes. In this study, the surface erosion threshold τc for cohesive sediments collected from two sites in the area of the Port of Hamburg in the River Elbe is investigated in laboratory experiments. An improved closed microcosm system (C-GEMS) is used for the

Using marine mussels to assess the potential ecotoxicological effects of two different commercial microplastics Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-05-04 David Daniel, Luis Barros, João Pinto da Costa, Ana Violeta Girão, Bruno Nunes
Microplastics (MPs) in the aquatic environment pose a serious threat to biota, by being confounded with food. These effects occur in mussels which are filter-feeding organisms. Mussels from the genus Mytilus were used to evaluate the ecotoxicological effects of two MPs, polypropylene (PP) and polyethylene terephthalate (PET), after 4 and 28-days. Measured individual endpoints were condition index and

Polycyclic aromatic hydrocarbons in seawater after the mysterious oil spill of 2019 on the Pernambuco coast, northeast Brazil Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-05-04 Thayane Cristina da S. Moreira, Ana Flávia B. de Oliveira, Pedro Gabriel C. de Lucena, Estefani S. do Nascimento, Leonardo M.F. de Almeida, Cristiane Maria V. de Araújo-Castro, Lino Angel V. Rojas, Gilvan T. Yogui, Eliete Zanardi-Lamardo, Jandyson M. Santos
In 2019, one of Brazil's most significant environmental disasters occurred, involving an oil spill that directly affected Pernambuco state. Contamination along the coast was evaluated by the quantification of polycyclic aromatic hydrocarbons (PAHs) in fifty seawater samples collected in the summer and winter of 2021. Analysis using fluorescence spectroscopy revealed that for all the samples, levels

Mass flowering and unprecedented extended pseudovivipary in seagrass (Posidonia oceanica) after a Marine Heat Wave Mar. Pollut. Bull. (IF 5.8) Pub Date : 2024-05-04 Fiona Tomas, Gema Hernan, Julia Mañez-Crespo, Andrés Arona, Daniela Haverbeck Meléndez, Xesca Reynés, Jonatan Delgado, Gabriele Procaccini, Enric Ballesteros
Seagrasses are marine flowering plants that create critical coastal ecosystems and are threatened by warming. Clonal expansion is generally the dominant strategy for meadow recovery, while sexual reproduction strongly differs among species (e.g., monoecious and diecious species, some creating seed banks, viviparous seedlings). In 2022, the Western Mediterranean underwent unprecedented warming, and
