Enhanced Rock Weathering for Carbon Removal-Monitoring and Mitigating Potential Environmental Impacts on Agricultural Land.

Terrestrial enhanced rock weathering (ERW) is the application of pulverized silicate rock to soils for the purposes of carbon removal and improved soil health. Although a geochemical modeling framework for ERW in soils is emerging, there is a scarcity of experimental and field trial data exploring potential environmental impacts, risks, and monitoring strategies associated with this practice. This paper identifies potential negative consequences and positive cobenefits of ERW scale-up and suggests mitigation and monitoring strategies.

Dominance of benthic fluxes in the oceanic beryllium budget and implications for paleo-denudation records.

The ratio of atmosphere-derived Be to continent-derived Be in marine sediments has been used to probe the long-term relationship between continental denudation and climate. However, its application is complicated by uncertainty in Be transfer through the land-ocean interface. The riverine dissolved load alone is insufficient to close the marine Be budget, largely due to substantial removal of riverine Be to continental margin sediments.

Diet shapes cold-water corals bacterial communities.

Different cold-water coral (CWC) species harbour distinct microbial communities and the community composition is thought to be linked to the ecological strategies of the host. Here we test whether diet shapes the composition of bacterial communities associated with CWC. We compared the microbiomes of two common CWC species in aquaria, Lophelia pertusa and Madrepora oculata, when they were either starved, or fed respectively with a carnivorous diet, two different herbivorous diets, or a mix of the 3.

Qualitative impact of salinity, UV radiation and turbulence on leaching of organic plastic additives from four common plastics - A lab experiment.

Four common consumer plastic samples (polyethylene, polystyrene, polyethylene terephthalate, polyvinylchloride) were studied to investigate the impact of physical parameters such as turbulence, salinity and UV irradiance on leaching behavior of selected plastic components. Polymers were exposed to two different salinities (i.e.
