      Cobalt is an essential nutrient for microbes in the ocean and is scarce in most areas of the ocean. This study measured cobalt concentrations in the Arctic Ocean for the first time, and found that cobalt is extremely high in the surface waters of Canadian Arctic. Although the cobalt primarily originates from the shelf, the high concentrations persist throughout the central Arctic. The cobalt in the Arctic appears to be increasing over time, and might be a source of cobalt to the North Atlantic.

      This paper reports the first estimate of the status of bacteria in long-distance-transported Asian dust, demonstrating that airborne dust, which can carry viable and nonviable bacteria on particle surfaces, is an efficient medium for constantly spreading bacteria at regional and even global scales. Such data are essential to better model and understand the roles and activities of bioaerosols in environmental evolution and climate change, and the potential risks of bioaerosols to human health.

      Silicon is taken up by some plants to increase structural stability and to develop stress resistance, and is rejected by others. To explore the underlying mechanisms we used the stable isotopes of silicon that shift in their relative abundance depending on the biochemical transformation involved. On species with a rejective (tomato, mustard) and active (wheat) uptake mechanism, grown in hydroculture, we found that the transport of silicic acid is controlled by the precipitation of biogenic opal.

      Worldwide, peatlands are important sources of dissolved organic matter (DOM) and trace metals (TMs) to surface waters, and these fluxes may increase with peatland degradation. In Southeast Asia, tropical peatlands are being rapidly deforested and drained. This work aims to address the fate of organic carbon and its role as a trace metal carrier in drained peatlands of Indonesia.

      Lakes are important emitters of the greenhouse gas methane. We use field observations and a model to evaluate the importance of known drivers of methane production and release. Fast and slow changes of the diffusive flux were governed by wind speed and sediment temperature, respectively. Increased turbulence enhanced release, but storms depleted the lakes of gas and limited emissions. Our findings may inform model studies on the effects of weather and climate change on lake methane emissions.

      We describe a method for correcting errors in oxygen optode measurements on autonomous platforms in the ocean. The errors result from the relatively slow response time of the sensor. The correction method includes an in-situ determination of the effective response time and requires the time stamps of the individual measurements. It is highly relevant for the BGC Argo program and also applicable to gliders. We also explore if diurnal changes in oxygen can be obtained from profiling floats.

      Ocean deoxygenation and warming are observed and projected to intensify under continued greenhouse gas emissions. Whereas temperature is considered the main climate change indicator, we show that in certain regions, thermocline doxygenation may be detectable before warming.

      Unexpectedly high diversity was revealed in areas licenced for polymetallic nodule mining exploration in the Pacific Ocean. For the first time, a comprehensive reference library including 287 novel ophiuroid sequences allocated to 43 species was produced. Differences in food availability along the nodule province of CCZ were reflected in the biodiversity patterns observed. The APEI3's dissimilarity with the exploration contract areas questions its ability to serve as a biodiversity reservoir.

      Drained peatlands (peat areas where ditches have been excavated to enhance plant production) are one of the main sources of carbon dioxide emissions globally. Blocking those ditches by building dams is a common strategy to restore the self-sustaining peat ecosystem and to mitigate carbon dioxide emissions. Where should those dams be located in order to maximize the benefits' Our work tackles that question making use of available data, hydrological modeling and numerical optimization methods.

      Carbon dioxide is produced by soil microbes through respiration, which is particularly fast when soils are moistened by rain. Will respiration increase with future more intense rains and longer dry spells' With a mathematical model, we show that wetter conditions increase respiration. In contrast, if rainfall totals stay the same, but rain comes all at once after long dry spells, the average respiration will not change, but the contribution of the respiration bursts after rain will increase.

      The northern Indian Ocean hosts an extensive oxygen minimum zones (OMZ), which intensified due to human-induced global changes. This includes the occurrence of anoxic events on the Indian shelf, affects benthic ecosystems, and the pelagic ecosystem structure in the Arabian Sea. Consequences for biogeochemical cycles are unknown, which, in addition to the poor representation of mesoscale features reduces the reliability of predictions of the future OMZ development in the northern Indian Ocean.

    • Abstract: Warming enhances carbon dioxide and methane fluxes from Red Sea seagrass (Halophila stipulacea) sediments
      Celina Burkholz, Neus Garcias-Bonet, and Carlos M. Duarte
      Biogeosciences, 17, 1717–1730, https://doi.org/10.5194/bg-17-1717-2020, 2020
      Seagrass meadows store carbon in their biomass and sediments, but they have also been shown to be sources of carbon dioxide (CO2) and methane (CH4). We experimentally investigated the effect of warming and prolonged darkness on CO2 and CH4 fluxes in Red Sea seagrass (Halophila stipulacea) communities. Our results indicated that sublethal warming may lead to increased emissions of greenhouse gases from seagrass meadows which may contribute to further enhance global warming.

      This study offered detailed information on dFe concentrations, distribution and the magnitude of yield in the Rajang River, the largest river in Malaysia. Three blackwater rivers, draining from peatlands, were also included in our study. Compared with the Rajang River, the dFe concentrations and yield from three blackwater rivers were much higher. The precipitation and agricultural activities, such as palm oil plantations, may markedly increase the concentration dFe in these tropical rivers.

      Analysing the impact of environmental changes due to climate change, e.g. geographical spread of climate-sensitive infections (CSIs) and agriculture crop modelling, may require land surface modelling (LSM) to predict future land surface conditions. There are multiple LSMs to choose from. The paper proposes a multivariate spatio-temporal data science method to understand the inherent uncertainties in four LSMs and the variations between them in Nordic areas for the net primary production.

  • Microstructure and composition of marine aggregates as co-determinants for
           vertical particulate organic carbon transfer in the global ocean

      Marine micro-algae bind carbon dioxide, CO2. During their decay, snowflake-like aggregates form that sink, remineralize and transport organically bound CO2 to depth; this is referred to as the biological carbon pump. In our model study, we elucidate how variable aggregate composition impacts the global pattern of vertical carbon fluxes. Our mechanistic model approach advances the representation of the global biological carbon pump and promotes a more realistic projection under climate change.

  • Oxygen isotope composition of waters recorded in carbonates in strong
           clumped and oxygen isotopic disequilibrium

    • Abstract: Oxygen isotope composition of waters recorded in carbonates in strong clumped and oxygen isotopic disequilibrium

      Paleoenvironment reconstructions, retrieved from δ18O and Δ47 values measured in carbonate, are compromised when crystallization occurs in isotopic disequilibrium. We show that some paleoenvironmental information can still be retrieved from these paired disequilibrium Δ47 and δ18O values. The possibility of retrieving information on paleowaters, sediments' interstitial waters, or organisms' body water at the carbonate precipitation loci will help understand past Earth and life evolution.

      Marine silicate weathering is a key process of the marine silica cycle; however, its controlling processes are not well understood. In the Guaymas Basin, silicate weathering has been studied under markedly differing ambient conditions. Environmental settings like redox conditions or terrigenous input of reactive silicates appear to be major factors controlling marine silicate weathering. These factors need to be taken into account in future oceanic mass balances of Si and in modeling studies.

      Besides the well-known role of tropical forests for CO2 capture, their soils can also consume CH4 and emit N2O, a GHG 300 times stronger than CO2. In this study, we quantified the soil emission/consumption of CO2, CH4 and N2O of tropical forests located in the northern Ecuadorian Andes. We observed a net consumption of N2O at higher altitudes, indicating a probably unaccounted sink. Our results highlight the importance of tropical forests as a means of mitigation to curb global warming.

      Major research initiatives have been undertaken within the Arctic Ocean, highlighting this region's global importance and vulnerability to climate change. In 2015 the international GEOTRACES program addressed this importance by devoting intense research activities to the Arctic Ocean. Among various tracers, we use Radium and carbonate system data to shed light on functioning and vulnerability of the hydrographic regime of the Canadian Arctic Archipelago, bridging Pacific and Atlantic Oceans.
