The Global Ocean Data Analysis Project (GLODAP) collects oceanographic datasets from research cruises that are needed to study the marine carbon cycle. The datasets are quality controlled and adjusted where necessary to ensure consistency between cruises, and published as a global data product. Here, we present a new method for calculating the consistency adjustments called ‘furthest-first inversion’ which has been developed for the newest version of the data product.

Marine sediments are excellent archives for reconstructing past changes in climate and ocean circulation. Yet, dating uncertainties, particularly during the 20th century, pose major challenges. Here we propose a novel chronostratigraphic approach that uses anthropogenic signals, such as the oceanic 13C Suess effect and spheroidal carbonaceous fly-ash particles, to reduce age model uncertainties in high-resolution marine archives over the 20th century.

Ocean acidification, a direct consequence of the CO2 release by human activities, is a serious threat to marine ecosystems. In this study, we conduct a detailed investigation of the acidification of the Nordic Seas, from 1850 to 2100, by using a large set of samples taken during research cruises together with numerical model simulations. We estimate the effects of changes in different environmental factors on the rate of acidification and its potential effects on cold-water corals.

This study provides monthly year-long dataset of nitrous oxide and methane concentrations and their air-sea exchange in understudied coastal areas of the Mediterranean Sea. By using standardized methods across multiple sites, it reveals marked seasonal and regional differences, with methane showing highly variable bursts linked to local sources. The dataset addresses major observational gaps and offers a reliable foundation for future environmental evaluation in this sensitive region.

We measured the age of Atlantic waters using man-made gases and a radioactive isotope. Age increases with depth: young surface waters are about 30 years old, deep Antarctic water reaches 100 years, and the oldest bottom water is roughly 120 years. The western Atlantic is younger and better ventilated than the east. These patterns help estimate deep-sea oxygen use and are key for climate models and marine ecosystems.

CARIMED (CARbon, tracers, and ancillary data In the MEDiterranean Sea) is a high-quality, FAIR (Findability, Accessibility, Interoperability, and Reusability) dataset integrating hydrographic, biogeochemical, and transient tracer data from 46 research cruises (1976–2018) across the Mediterranean Sea. The data underwent rigorous, basin-adapted quality control to remove systematic biases, unifying four decades of fragmented data, delivering two complementary products: the aggregated original cruise data product and the bias-adjusted data synthesis product.

Human activities have emitted large amounts of carbon dioxide (CO2) into the atmosphere since the beginning of the industrial revolution and this human-emitted CO2 (Cant) is absorbed by the ocean. We use autonomous robotic to show that the Cant content in the upper 2000 dbar of the Irminger Sea increased roughly steadily over 2011–2016, then reached a stationary state between 2016 and 2021. This study highlights how the monthly resolution of Argo data can complement ship-based measurements.

The Global Ocean Data Analysis Project (GLODAP) collects oceanographic datasets from research cruises that are needed to study the marine carbon cycle. The datasets are quality controlled and adjusted where necessary to ensure consistency between cruises, and published as a global data product. Here, we present a new method for calculating the consistency adjustments called ‘furthest-first inversion’ which has been developed for the newest version of the data product.

Remineralised carbon storage is projected to increase along the 21st century, but the magnitude of increase varies depending on the Earth system models. To constrain projections, we explore the relationship between remineralised carbon and deep ocean circulation. We show that the sensitivity of remineralised carbon to circulation slowdown varies considerably between models. More observational data and a larger model ensemble is needed to constrain projections of remineralised carbon storage.

Transient tracer data, measured for the first time in 2022 in the Gulf of St. Lawrence, reveal older deep waters in the east than the west, contrary to expected estuarine circulation, indicating increased influence of older, warmer, less oxygenated North Atlantic Central Water over younger, oxygen-rich Labrador Current Water. While consistent with previous reports of increasing NACW contribution, our results contradict claims of a complete shift to NACW by 2021, showing that LCW still persists.

This study compares coupled ocean–atmosphere models, reanalyses, and satellite data for 1991–2020 in the Barents and Kara Seas, where Arctic sea‑ice loss has been greatest. The results evaluate how well these products asses sea ice and ocean temperature. Reanalyses and satellites show strong sea‑ice decline, while models show little or none – only HIRHAM‑NAOSIM shows a weak decline in the Barents Sea. Reanalyses also indicate stronger mixed‑layer warming then the models, especially in autumn.

We analyzed three decades of carbon concentration and transport in the subpolar gyre of the North Atlantic Ocean, a key region in ocean carbon cycle. Natural carbon remained stable, but human-derived carbon rose by over 30 %. Upper layers exhibit strong seasonal to interannual variability driven by physical and biological processes. Carbon transport was tightly linked to circulation patterns. In the longterm, transport of human-derived carbon is proportional to the increase in its concentration.

Ocean acidification threatens marine ecosystems and the climate and is commonly assessed through ocean pH measurements. This study provides a new twenty-year dataset of pH measurements from the North Atlantic, derived from the correction and reevaluation of both historical and recent pH measurements affected by methodological bias. This revised dataset enables a more accurate reassessment of pH trends and carbon variables under novel and updated methodological standards.

Oxygen is essential to marine life, but the amount of oxygen in the ocean has been decreasing in recent decades. Using observations of oxygen concentration interpolated across a section of the subtropical North Atlantic Ocean, we show that deoxygenation in the region is primarily driven by an increase in oxygen being consumed during remineralisation of organic matter. The impact of this is strongest at depths of around 600 m, where the process drives up to 70 % of the total deoxygenation.

We studied how riverine water from the mainland of Japan affects the ocean's carbon cycle using decades of Total Alkalinity (TA) data from the Northwest Pacific. Statistical analysis revealed riverine water as a major TA source, reducing coastal acidification by 71 %, but with minimal impact on pH and atmospheric CO2 absorption. Future work aims to refine results with depth-specific data and apply findings to global models.

Here we used the anthropogenic radionuclides I-129 and U-236 as tracers for Atlantic Water circulation in the Arctic Ocean. New data collected in 2021 allowed to assess the distribution of Atlantic Water and mixing with Pacific-origin water in the surface layer in that year. By using historical tracer data from 2011 to 2021, we looked into temporal changes of the circulation and found slightly older waters in the central Arctic Ocean in 2021 compared to 2015.

The Mediterranean Sea is changing rapidly, underscoring the urgent need for high-quality datasets to quantify trends and assess impacts on biogeochemical cycles. O2 is a key indicator of marine ecosystem health and plays a central role in CO2 and nutrient cycling. We compiled a regional-scale dataset of O2 in the western Mediterranean to provide a robust observational foundation for assessing O2 variability, associated with climate change, and anomalies related to deoxygenation processes.

We combine two decades of oxygen data with new carbon observations and a tracer-informed model to quantify oxygen loss and carbon buildup in the deep waters of the Gulf and Lower St. Lawrence Estuary. We then test a novel idea: reoxygenating these waters with the oxygen produced as a by-product from green-hydrogen production. Our results suggest this could significantly reduce hypoxia, though full recovery would require larger inputs.

Nitrous oxide (N2O), a potent greenhouse gas, is understudied in coastal zones. We present N2O concentrations and air–sea fluxes from the Balearic coast (2018–2023). Concentrations varied slightly across sites, with areas acting as weak sources or being near equilibrium. Temperature was the main driver of seasonal changes. These findings improve our understanding of coastal N2O emissions.

The study evaluated CO2–carbonate system dynamics in the North Atlantic subpolar gyre during 2009–2019. Significant ocean acidification, largely due to rising anthropogenic CO2 levels, was found. Cooling, freshening, and enhanced convective processes intensified this trend, affecting calcite and aragonite saturation. The findings contribute to a deeper understanding of ocean acidification and improve our knowledge about its impact on marine ecosystems.

We calculate the amount of anthropogenic carbon (Cant) in the Atlantic for the years 1990, 2000, 2010 and 2020. Cant is the carbon that is taken up by the ocean as a result of humanmade CO2 emissions. To determine the amount of Cant, we apply a technique that is based on the observations of other humanmade gases (e.g., chlorofluorocarbons). Regionally, changes in ocean ventilation have an impact on the storage of Cant. Overall, the increase in Cant is driven by the rising CO2 in the atmosphere.

We study the Atlantic Meridional Overturning Circulation (AMOC) measured between Greenland and Portugal between 1993–2021. We identify changes in AMOC limb volume and velocity as two major drivers of AMOC variability at subpolar latitudes. Volume variations dominate on the seasonal timescale, while velocity variations are more important on the decadal timescale. This decomposition proves useful for understanding the origin of the differences between AMOC time series from different analyses.

For assessing the consequences of human-induced climate change for the marine realm, it is necessary to not only look at gradual changes but also at abrupt changes of environmental conditions. We summarise abrupt changes in ocean warming, acidification, and oxygen concentration as the key environmental factors for ecosystems. Taking these abrupt changes into account requires greenhouse gas emissions to be reduced to a larger extent than previously thought to limit respective damage.

The Mediterranean Sea is a heavily trafficked shipping area, and air quality monitoring stations in numerous cities along the Mediterranean coast have detected high levels of air pollutants originating from shipping emissions. The current study investigates how existing restrictions on shipping-related emissions to the atmosphere ensure compliance with legislation. Focus was laid on fine particles and particle species, which were simulated with five different chemical transport models.

Potential ship impact on air pollution in the Mediterranean Sea was simulated with five chemistry transport models. An evaluation of the results for NO2 and O3 air concentrations and dry deposition is presented. Emission data, modeled year and domain were the same. Model run outputs were compared to measurements from background stations. We focused on comparing model outputs regarding the concentration of regulatory pollutants and the relative ship impact on total air pollution concentrations.

Long-term ecological observations are key to assess, understand and predict impacts of environmental change on biotas. We present a multidisciplinary framework for such largely lacking investigations in the East Antarctic Southern Ocean, combined with case studies, experimental and modelling work. As climate change is still minor here but is projected to start soon, the timely implementation of this framework provides the unique opportunity to document its ecological impacts from the very onset.

marine particlescomprises detrital aggregates; fecal pellets; bacterioplankton, phytoplankton and zooplankton; and even fish. Here, we present a global dataset that contains 8805 vertical particle size distribution profiles obtained with Underwater Vision Profiler 5 (UVP5) camera systems. These data are valuable to the scientific community, as they can be used to constrain important biogeochemical processes in the ocean, such as the flux of carbon to the deep sea.

Tides affect the marine carbonate chemistry of a coastal polynya neighbouring the Ekström Ice Shelf by movement of seawater with different physical and biogeochemical properties. The result is that the coastal polynya in the summer can switch between being a sink or a source of CO2 multiple times a day. We encourage consideration of tides when collecting in polar coastal regions to account for tide-driven variability and to avoid overestimations or underestimations of air–sea CO2 exchange.

There is confusion in the literature on interactions of dissolved phosphate and sulphate with the alkalinity of seawater. These do play a minor role in the titration to determine alkalinity. However, a perceived biological role of phosphate and sulphate has been suggested in the value of Oceanic Alkalinity. We think this is mistaken. Some other minor issues additionally have led to confusion on the exact description of Alkalinity. We treat those against a theoretical and empirical background.

The CISE-LOCEAN seawater stable isotope dataset has close to 8000 data entries. The δ18O and δD isotopic data measured at LOCEAN have uncertainties of at most 0.05 ‰ and 0.25 ‰, respectively. Some data were adjusted to correct for evaporation. The internal consistency indicates that the data can be used to investigate time and space variability to within 0.03 ‰ and 0.15 ‰ in δ18O–δD17; comparisons with data analyzed in other institutions suggest larger differences with other datasets.

Ocean acidification, a direct consequence of the CO2 release by human activities, is a serious threat to marine ecosystems. In this study, we conduct a detailed investigation of the acidification of the Nordic Seas, from 1850 to 2100, by using a large set of samples taken during research cruises together with numerical model simulations. We estimate the effects of changes in different environmental factors on the rate of acidification and its potential effects on cold-water corals.

We use data crossing Herald Canyon in the Chukchi Sea collected in 2008 and 2014 together with numerical modelling to investigate the circulation in the western Chukchi Sea. A large fraction of water from the Chukchi Sea enters the East Siberian Sea south of Wrangel Island and circulates in an anticyclonic direction around the island. To assess the differences between years, we use numerical modelling results, which show that high-frequency variability dominates the flow in Herald Canyon.

For the Baltic Sea countries, shipping emissions are an important source of air pollution. This study investigates the contribution of shipping emissions to the acidification and eutrophication of soils and freshwater within the airshed of the Baltic Sea in the years 2012 and 2040. The implementation of emission control areas and improving energy efficiency significantly reduces the negative impact on ecosystems expressed as a decrease in the exceedance of critical loads for sulfur and nitrogen.

Short summary
The GLODAPv2 data product collects data from more than 700 hydrographic cruises into a global and internally calibrated product. It provides access to the data from almost all ocean carbon cruises carried out since the 1970s and is a unique resource for marine science, in particular regarding the ocean carbon cycle. GLODAPv2 will form the foundation for future routine synthesis of hydrographic data of the same sort.
