Short summary
We developed a model to simulate seafloor biogeochemical processes across a wide range of marine environments, from shallow coastal zones to deep-sea sediments. From this model, we derived a set of simple equations that predict how carbon, oxygen, and alkalinity are exchanged between sediments and overlying waters. These equations provide an efficient way to improve how ocean models represent seafloor interactions, which are often missing or overly simplified.

This study evaluates the potential of combining continuous atmospheric CO2 flux measurements with IA modelling to estimate carbon budgets in agricultural crops in a French wetland. Modelling strategies were developed to capture their phenological and management-related carbon dynamics. Our results provide a pragmatic framework to derive plot-scale carbon budgets and offers promising perspectives for improving regional carbon flux inventories and assessing climate-smart agricultural practices.

This study examines the particulate organic matter (POM) composition and dynamics in 23 temperate rivers. Carbon and nitrogen isotope analysis revealed four river types based on dominant POM sources (phytoplankton, terrestrial POM). Catchment characteristics influence POM composition while seasonal variations in river flow and sediment resuspension drive POM dynamics. This study improves the understanding of river systems and calls for further studies exploring downstream estuarine functioning.

We adjusted a model of the Mackenzie River region to account for the riverine export of organic matter that affects light in the water. We show that such export causes a delay in the phytoplankton growth by two weeks and raises the water surface temperature by 1.7 °C. We found that temperature increase turns this coastal region from a sink of carbon dioxide to an emitter. Our findings suggest that rising exports of organic matter can significantly affect the carbon cycle in Arctic coastal areas.

In a salt marsh, we performed seasonal 24 h cycles to look for aquatic metabolism influence on water carbon dynamics and net ecosystem CO2 exchanges (NEEs). From high to low tide in winter, marsh anaerobic respiration generated the highest levels of dissolved inorganic carbon and alkalinity. On the contrary, in spring and summer, marsh primary production led to CO2-depleted water exports downstream. At high tide, aquatic heterotrophy can influence NEE during the highest immersion levels only.

Our research highlights the concerning impact of rising carbon dioxide levels on coastal areas. To better understand these changes, we've established an observation network in France. By deploying pH sensors and other monitoring equipment at key coastal sites, we're gaining valuable insights into how various factors, such as freshwater inputs, tides, temperature, and biological processes, influence ocean pH.

We present two space- and time-resolved zooplankton datasets originating from samples collected in the Bay of Biscay in spring over the 2004–2019 period and imaged with the interoperable imaging systems ZooScan and ZooCAM. These datasets are suited for long-term size-based or combined size- and taxonomy-based ecological studies of zooplankton. The set of sorted images are provided along with a set of morphological descriptors that are useful when machine learning is applied to plankton studies.

Short summary
We deployed an atmospheric eddy covariance system to measure continuously the net ecosystem CO2 exchanges (NEE) over a salt marsh and determine the major biophysical drivers. Our results showed an annual carbon sink mainly due to photosynthesis of the marsh plants. Our study also provides relevant information on NEE fluxes during marsh immersion by decreasing daytime CO2 uptake and night-time CO2 emissions at the daily scale, whereas the immersion did not affect the annual marsh C balance.

Short summary
We simulate the benthic microalgae seasonal cycle on a temperate intertidal mudflat by combining a physical–biological coupled model with remotely sensed and in situ data. While optimal light and temperature conditions lead to a spring bloom, thermo-inhibition and grazing result in a summer depression of biomass. The model ability to infer mechanisms driving the seasonal cycle could open the door to the contribution of productive intertidal biofilms to the coastal carbon cycle.
