This study analyzes the mechanisms driving nitrate retention and elimination within a large estuarine system. Simultaneous measurements of pelagic and benthic processes provide insight into how nitrates are transformed. Finally, our findings are consistent with the paradigm that eutrophication favors a shift from benthic to pelagic-dominated processes.

In this paper, we present the first edition of a global database compiling previously published and unpublished measurements of dissolved organic matter (DOM) collected in coastal waters (CoastDOM v1). Overall, the CoastDOM v1 dataset will be useful to identify global spatial and temporal patterns and to facilitate reuse in studies aimed at better characterizing local biogeochemical processes and identifying a baseline for modelling future changes in coastal waters.

Peatland rewetting is known to reduce dissolved nutrients and greenhouse gases; however, short-term nutrient leaching and high CH4 emissions shortly after rewetting are likely to occur. We investigated the rewetting of a coastal peatland with brackish water and its effects on nutrient release and greenhouse gas fluxes. Nutrient concentrations were higher in the peatland than in the adjacent bay, leading to an export. CH4 emissions did not increase, which is in contrast to freshwater rewetting.

Inland waters play an important role in the global carbon cycle by storing, transforming and transporting carbon from land to sea. Comparatively little is known about carbon dynamics at the river–estuarine transition. A study of tributaries of Chesapeake Bay showed that biological processes exerted a strong effect on carbon transformations. Peak carbon retention occurred during periods of elevated river discharge and was associated with trapping of particulate matter.

Irrespective of variable environmental settings in estuaries, the quality of organic particles is an important factor controlling microbial processes that facilitate a reduction of land-derived nitrogen loads to the open sea. Through the interplay of biogeochemical processing, geomorphology, and hydrodynamics, organic particles may function as a carrier and temporary reservoir of nitrogen, which has a major impact on the efficiency of nitrogen load reduction.

Coccolithophores contribute to the global carbon cycle and their calcite structures (coccoliths) are used as a palaeoproxy to understand past oceanographic conditions. Here, we compared three frequently used methods to estimate coccolith mass from the model species Emiliania huxleyi and the results allow for a high level of comparability between the methods, facilitating future comparisons and consolidation of mass changes observed from ecophysiological and biogeochemical studies.

Knowledge of carbon isotope fractionation is important for the assessment of the pathways involved in the degradation of organic matter. Formate is an important intermediate during this process. It was mainly converted to carbon dioxide and acetate both in the presence and absence of sulfate. Methane was only a minor product and was mainly formed from the acetate. The acetate was depleted in the heavy carbon atom relative to formate, while the carbon dioxide was enriched.

Sugar compounds in air can trace the source of bioaerosols that affect public health and climate. In rural north China, we observed increased fungal activity at night and less variable bacterial community diversity. Certain night-increasing sugar compounds were more closely related to fungi than bacteria. The fungal community greatly influenced sugar compounds, while bacteria played a limited role. Caution is advised when using sugar compounds to trace airborne microbes, particularly bacteria.

Applications of the mineral olivine are a promising means to capture carbon dioxide via coastal enhanced weathering, but little is known about the impacts on important marine phytoplankton. We examined the effects of olivine dissolution products on species from three major phytoplankton groups: diatoms, coccolithophores, and cyanobacteria. Growth and productivity were generally either unaffected or stimulated, suggesting the effects of olivine on key phytoplankton are negligible or positive.

Permafrost thaw initiates thermokarst landscape formation, resulting in distinct new habitats, including degraded permafrost soil, thermokarst lake sediments, and lake water. These distinct habitats harbored differentiated bacterial communities that originated from the same source, differing in diversity, assembly mechanisms, and environmental influences. The results imply ecological consequences of permafrost degradation in the face of further climate change.

We report taxon-specific biogeography of N2-fixing microbes (diazotrophs) driven by Kuroshio intrusion (KI) into the South China Sea. We show that the composition and distribution of distinct diazotrophic taxa shift with KI-induced variations in physicochemical parameters of seawater, and that KI shapes diazotrophic community as primarily a stochastic process. This study thus has implications for the redistribution of diazotrophs in a future warming ocean as KIs are projected to intensify.

Earthquake-induced soil liquefaction poses a significant global threat. Microbially induced desaturation and precipitation (MIDP) via denitrification is a potentially sustainable, non-disruptive bacteria-driven ground improvement technique under existing structures. We developed a next-generation biogeochemical model to understand and predict the behavior of MIDP in the natural environment to design field-based hazard mitigation treatments.

Short summary
In forests, trees allocate a significant amount of carbon belowground to support mycorrhizal symbiosis. In northern forests nitrogen normally regulates this allocation and consequently mycorrhizal fungi growth. In this study we demonstrate that in a conifer forest from Sweden, fungal growth is regulated by phosphorus instead of nitrogen. This is probably due to an increase in nitrogen deposition to soils caused by decades of human pollution that has altered the ecosystem nutrient regime.

We found that increasing light intensity compensates for the negative effects of low phosphorus (P) availability on cellular protein and nitrogen contents. Reduced P availability, increasing light intensity, and ocean acidification act synergistically to increase cellular contents of carbohydrate and POC and the allocation of POC to carbohydrate. These regulation mechanisms in Emiliania huxleyi could provide vital information for evaluating carbon cycle in marine ecosystems under global change.

Microbial ecosystems have been found in all subglacial environments sampled to date. Yet, little is known of the sources of energy and nutrients that sustain these microbial populations. This study shows that crushing of sedimentary rocks, which contain organic carbon, carbonate and sulfide minerals, along with previously weathered silicate minerals, produces a range of compounds and nutrients which can be utilised by the diverse suite of microbes that inhabit glacier beds.

We show, for the first time, that pure cultures of the cyanobacterium Microcystis aeruginosa can synthesize the potent greenhouse gas N2O using nitrite as substrate. Our findings have broad environmental implications because M. aeruginosa is globally found in freshwater ecosystems and is often the dominant species found in algae blooms. Further research is now needed to determine the occurrence and significance of N2O emissions from ecosystems rich with M. aeruginosa.

We present a study linking rain, meteorology, and mountain lake phytoplankton dynamics on the basis of a case study at Aydat (France) in September 2020. The air mass origin mainly influences the rain chemical composition, which depends on the type of rain, convective or stratiform. Our results also highlighted a non-negligible presence of photosynthetic cells in rainwater. The impact of the atmospheric forcing on the lake could play a key role in phytoplankton dynamics in the temperate zone.

Bacteria use extracellular enzymes to cut large organic matter to sizes small enough for uptake. We compared the enzymatic response of surface, mid-water, and deep-ocean bacteria to complex natural substrates. Bacteria in surface and mid-depth waters produced a much wider range of enzymes than those in the deep ocean and may therefore consume a broader range of organic matter. The extent to which organic matter is recycled by bacteria depends in part on its residence time at different depths.

Ocean alkalinity enhancement has the capacity to remove vast quantities of carbon from the atmosphere, but its effect on marine ecosystems is largely unknown. We assessed the effect of increased alkalinity on a coastal phytoplankton community when seawater was equilibrated and not equilibrated with atmospheric CO2. We found that the phytoplankton community was moderately affected by increased alkalinity and equilibration with atmospheric CO2 had little influence on this effect.

Eddies are ubiquitous in the ocean and alter physical, chemical, and biological processes. However, how they affect organic carbon production and consumption is largely unknown. Here we show how an eddy triggers a cascade effect on biomass production and metabolic activities of phyto- and bacterioplankton.

Fungi living in symbiosis with tree roots can accumulate belowground, forming special tissues than can repel water. We measured the water repellency of organic material incubated belowground and correlated it with fungal growth. We found a positive association between water repellency and root symbiotic fungi. These results are important because an increase in soil water repellency can reduce the release of CO2 from soils into the atmosphere and mitigate the effects of greenhouse gasses.

Reconstructions of past CO2 concentrations rely on proxy estimates, with one line of proxies relying on the CO2-dependence of stable carbon isotope fractionation in marine phytoplankton. Culturing experiments provide insights into which processes may impact this. We found, however, that the methods with which these culturing experiments are performed also influence 13C fractionation. Caution should therefore be taken when extrapolating results from these experiments to proxy applications.

This work focuses on one of the essential pathways of mycorrhizal impact on C cycles: the mediation of plant litter decomposition. We present a model based on litter chemical quality which precludes a conclusive examination of mycorrhizal impacts on soil C. It improves long-term decomposition predictions and advances our understanding of litter decomposition dynamics. It creates a benchmark in quantitatively examining the impacts of plant–microbe interactions on soil C dynamics.

Saharan dust deposition of nutrients and trace metals is crucial to microbes in the Mediterranean Sea. Here, we tested the response of microbial and viral communities to simulated dust deposition under present and future conditions of temperature and pH. Overall, the effect of the deposition was dependent on the initial microbial assemblage, and future conditions will intensify microbial responses. We observed effects on trophic interactions, cascading all the way down to viral processes.

Acetate is an important intermediate during the anaerobic degradation of organic matter. It is consumed by methanogenic and sulfidogenic microorganisms accompanied by stable carbon isotope fractionation. We determined isotope fractionation under different conditions in two paddy soils and two lake sediments and also determined the composition of the microbial communities. Despite a relatively wide range of experimental conditions, the range of fractionation factors was quite moderate.

A previous study documented an intense hydrothermal plume in the South Pacific Ocean; however, the iron release associated with this plume and the impact on microbiology were unclear. We describe metal concentrations associated with multiple hydrothermal plumes in this region and protein signatures of plume-influenced microbes. Our findings demonstrate that resources released from these systems can be transported away from their source and may alter the physiology of surrounding microbes.

Physicochemical determinants of microbiome architecture across continental shelves–slopes are unknown, so we explored the geomicrobiology along 3 m sediment horizons of seasonal (shallow coastal) and perennial (deep sea) hypoxic zones of the Arabian Sea. Nature, concentration, and fate of the organic matter delivered to the sea floor were found to shape the microbiome across the western Indian margin, under direct–indirect influence of sedimentation rate and water column O2 level.

Conceptual models link microbes with the environment but are untested. We test a recent model using riverbed sediments. We exposed sediments to disturbances, going dry and becoming wet again. As the length of dry conditions got longer, there was a sudden shift in the ecology of microbes, chemistry of organic matter, and rates of microbial metabolism. We propose a new model based on feedbacks initiated by disturbance that cascade across biological, chemical, and functional aspects of the system.

Microbes are the main drivers of productivity and nutrient cycling in the ocean. We present a combined approach assessing C and N uptake and microbial community diversity across ecological provinces in the Southern Ocean and southern Indian Ocean. Provinces showed distinct genetic fingerprints, but microbial activity varied gradually across regions, correlating with nutrient concentrations. Our study advances the biogeographic understanding of microbial diversity across C and N uptake regimes.

Biological rock crusts (BRCs) are common microbial-based assemblages covering rocks in drylands. BRCs play a crucial role in arid environments because of the limited activity of plants and soil. Nevertheless, BRC development rates have never been dated. Here we integrated archaeological, microbiological and geological methods to provide a first estimation of the growth rate of BRCs under natural conditions. This can serve as an affordable dating tool in archaeological sites in arid regions.

Our study is of interest to atmospheric scientists and environmental microbiologists, as we show that clouds can be considered a medium where bacteria efficiently degrade and transform amino acids, in competition with chemical processes. As current atmospheric multiphase models are restricted to chemical degradation of organic compounds, our conclusions motivate further model development.

The adverse atmospheric environmental conditions do not appear suited for microbial life. We conducted the first global comparative metagenomic analysis to find out if airborne microbial communities might be selected by their ability to resist these adverse conditions. The relatively higher concentration of fungi led to the observation of higher proportions of stress-related functions in air. Fungi might likely resist and survive atmospheric physical stress better than bacteria.

Through a comprehensive investigation, we observed differential niche partitioning among diverse ammonia-oxidizing archaea (AOA) sublineages in a typical subtropical estuary. Distinct AOA communities observed at DNA and RNA levels suggested that a strong divergence in ammonia-oxidizing activity among different AOA groups occurs. Our result highlights the importance of identifying major ammonia oxidizers at RNA level in future studies.

This study focuses on the chemical reaction between Fe(II) and nitrite, which has been reported to produce high levels of the greenhouse gas N2O. We investigated the extent to which dead biomass and Fe(II) minerals might enhance this reaction. Here, nitrite reduction was highest when both additives were present but less pronounced if only Fe(II) minerals were added. Both reaction systems show distinct differences, rather low N2O levels, and indicated the abiotic production of N2.

Bioluminescent bacteria, the most abundant light-emitting organisms in the ocean, can be free-living, be symbiotic or colonize organic particles. This review suggests that they act as a visual target and may indirectly influence the sequestration of biogenic carbon in oceans by increasing the attraction rate for consumers. We summarize the instrumentation available to quantify this impact in future studies and propose synthetic figures integrating these ecological and biogeochemical concepts.

Foraminifera are unicellular marine organisms that play an important role in the marine element cycle. Changes of environmental parameters such as salinity or temperature have a significant impact on the faunal assemblages. Our experiments show that changing salinity in the German Wadden Sea immediately influences the foraminiferal community. It seems that A. tepida is better adapted to salinity fluctuations than H. germanica.

Seamounts are globally abundant submarine structures that offer great potential to study the impacts and interactions of environmental gradients at a single geographic location. In an exemplary way, we describe potential mechanisms by which a seamount can affect the structure of pelagic and benthic (sponge-)associated microbial communities. We conclude that the geology, physical oceanography, biogeochemistry, and microbiology of seamounts are even more closely linked than currently appreciated.

The following paper highlights the importance of benthic N-transformation rates in different sediment types in the southern North Sea as a source of fixed nitrogen for primary producers and also as a sink of fixed nitrogen. Sedimentary fluxes of dissolved inorganic nitrogen support ∼7 to 59 % of the average annual primary production. Semi-permeable and permeable sediments contribute ∼68 % of the total benthic N2 production rates, counteracting eutrophication in the southern North Sea.

Mineral mining in deep-sea hydrothermal settings will lead to the formation of plumes of fine-grained, chemically reactive, suspended matter. Understanding how natural hydrothermal plumes evolve as they disperse from their source, and how they affect their surrounding environment, may help in characterising the behaviour of the diluted part of mining plumes. The natural plume provided a heterogeneous, geochemically enriched habitat conducive to the development of a distinct microbial ecology.

Trichodesmium is a globally important marine nitrogen fixer that stimulates primary production in the surface ocean. We surveyed metaproteomes of Trichodesmium populations across the North Atlantic and other oceans, and we found that they experience simultaneous phosphate and iron stress because of the biophysical limits of nutrient uptake. Importantly, nitrogenase was most abundant during co-stress, indicating the potential importance of this phenotype to global nitrogen and carbon cycling.

Tropospheric iodine takes part in numerous atmospheric chemical cycles, including tropospheric ozone destruction and aerosol formation. Due to its significance for atmospheric processes, it is crucial to constrain its sources and sinks. This paper aims at investigating and understanding features of biogenic iodate-to-iodide reduction in microalgal monocultures. We find that phytoplankton senescence may play a crucial role in the release of iodide to the marine environment.

Effects of biological activity on mineral weathering operate at scales ranging from short-term, microscopic interactions to global, evolutionary timescale processes. Microorganisms have had well-documented effects at large spatio-temporal scales, but to establish the quantitative significance of microscopic measurements for field-scale processes, higher-resolution studies of liquid chemistry at local weathering sites and improved upscaling to soil-scale dissolution rates are still required.

Sponge grounds are known as nutrient sources, providing nitrate and ammonium to the ocean. We found that they also can do the opposite: in six species from Arctic and North Atlantic sponge grounds, we measured high rates of denitrification, which remove these nutrients from the sea. Rates were highest when the sponge tissue got low in oxygen, which happens when sponges stop pumping because of stress. Sponge grounds may become nutrient sinks when exposed to stress.

Our field data show unhampered bacterial activity at low oxygen concentrations. Meanwhile bacterial degradation of organic matter substantially contributed to the formation of the OMZ.

A screening of more than 100 strains from 65 different species revealed that the ice nucleation activity within the fungal genus Fusarium is more widespread than previously assumed. Filtration experiments suggest that the single cell-free Fusarium IN is smaller than 100 kDa (~ 6 nm) and that aggregates can be formed in solution. Exposure experiments, freeze–thaw cycles, and long-term storage tests demonstrate a high stability of Fusarium IN under atmospherically relevant conditions.

Ice nucleation particles (INPs) help ice form at temperatures as high as −4 °C and contribute to the formation of precipitation. Leaf litter contains a high concentration of INPs, but the organisms that produce them are unknown. Here, we cultured two bacteria and one fungus from leaf litter that produce INPs similar to those found in leaf litter. This suggests that leaf litter may be an important habitat of these organisms and supports a role of these organisms as producers of atmospheric INPs.

In stony deserts, when rocks are exposed to atmospheric conditions, they undergo weathering. The cavernous (honeycomb) weathering pattern is one of the most common, but it is still unclear exactly how it is formed. We show that microorganisms, which differ from the surrounding soil and dust, form biological crusts on exposed rock surfaces. These microbes secrete polymeric substances that mitigate weathering by reducing evaporation rates and, consequently, salt transport rates through the rock.

This paper contributes to the study of bacterial carbon sequestration in mine tailings. Previous studies focused on carbonate mineral precipitation, while the role of autotrophs in carbon sequestration has been neglected. Carbon sequestration in two mine tailings treated with FeS2 was analyzed using 13C isotope labeling, pyrosequencing, and DNA SIP to identify carbon fixers. This paper is the first to investigate carbon sequestration by autotrophic groups in mine tailings.

Short summary
In fresh and brackish waters, algal blooms are often dominated by cyanobacteria, which have the ability to utilize atmospheric nitrogen. Cyanobacteria are also unusual in that they float to the surface and are dispersed by wind-driven currents. Their patchy and dynamic distribution makes it difficult to track their abundance and quantify their effects on nutrient cycling. We used remote sensing to map the distribution of cyanobacteria in a large Baltic lagoon and quantify their contributions.
In fresh and brackish waters, algal blooms are often dominated by cyanobacteria, which have the...
