Short summary
Short summary
Paleo-oxygen proxies can extend current records, constrain pre-anthropogenic baselines, provide datasets necessary to test climate models under different boundary conditions, and ultimately understand how ocean oxygenation responds on longer timescales. Here we summarize current proxies used for the reconstruction of Cenozoic seawater oxygen levels. This includes an overview of the proxy's history, how it works, resources required, limitations, and future recommendations.

We studied how artificial intelligence can speed up the study of tiny ocean organisms called benthic foraminifera, whose shells help scientists understand past ocean changes. Normally, identifying and counting them under a microscope takes a lot of time and skill. Here, we compared automated image analysis and human counting for 31 samples. The automated method showed promising results for faster and reliable research.

Small boat harbours are suggested to cause pollution and alien species introductions. Here we analysed surface sediments in Hinsholmskilen harbour (Sweden) for benthic foraminifera and potentially toxic elements. Molecular and morphological analyses of foraminifera show the presence of two alien species, Trochammina hadai and Ammonia confertitesta, whilst pollution is mostly low for Cd, Co, Ni, and Pb. In contrast, As, Zn, Cu, Hg, and Cr have high levels due to the use of these elements in boat paints.

Short summary
Coastal marine sediments are subject to major acidification processes because of climate change and human activities, but these processes can also result from biotic activity. We studied the sediment acidifcation effect on benthic calcareous foraminifera in intertidal mudflats. The strong pH decrease in sediments probably caused by cable bacteria led to calcareous test dissolution of living and dead foraminifera, threatening the test preservation and their robustness as environmental proxies.

Short summary
Coastal seas experience sediment discharges whose intensity and frequency can strongly be affected by human activities and climate change. We analysed the response of benthic species in an experimental set-up. After the burial under a single thick layer of sediment or multiple thin layers at different times, the analysed species migrate rapidly towards the surface. A stronger effect of a single thick deposit on standing stocks and biodiversity is visible compared to frequent low-sediment inputs.

This study is the first to show non-selective deposit feeding in the foraminifera Nonionella labradorica and the possible uptake of methanotrophic bacteria. We carried out a feeding experiment with a marine methanotroph to examine the ultrastructure of the cell and degradation vacuoles using transmission electron microscopy (TEM). The results revealed three putative methanotrophs at the outside of the cell/test, which could be taken up via non-targeted grazing in seeps or our experiment.

Short summary
The concentration of the trace metal barium (Ba) in coastal seawater is a function of continental input, such as riverine discharge. Our geochemical records of the severely hot and dry year 2018, and following wet year 2019, reveal that prolonged drought imprints with exceptionally low Ba concentrations in benthic foraminiferal calcium carbonates of coastal sediments. This highlights the potential of benthic Ba / Ca to trace past climate extremes and variability in coastal marine records.

Short summary
The study presents (1) a validation of a method which was previously published allowing us to recognize different Ammonia phylotypes (T1, T2 and T6) based only on their morphology and (2) a refined biogeographical distribution presented here supporting the putatively invasive character of phylotype T6. Results suggest that phylotype T6 is currently spreading out and supplanting autochthonous phylotypes T1 and T2 along the coastlines of the British Isles and northern France.

Short summary
We studied how tiny shelled organisms called foraminifera living in coastal mudflats respond to changes in their microscopic algae food. By monitoring a French mudflat every month for 3 years, we showed that seasonal environmental changes strongly shape both algae and foraminifera. Using simple algae traits such as size and shape explained feeding patterns better than identifying algae species, offering a clearer way to predict ecosystem responses to environmental change.
We studied how tiny shelled organisms called foraminifera living in coastal...
