Summary: Dissolved carbon (DC) in forest streams plays a crucial role in maintaining the structure and productivity of adjoining aquatic ecosystems as well as informing biogeochemical links between mountain forests and adjoining rivers. However, the functions of forest stream DC dynamics are rarely incorporated into river management. This study investigated the seasonal dynamics of DC in 15 representative forest streams in a geographically fragile subalpine-gorge catchment in the upper reaches of the Yangtze River. The results showed that precipitation, temperature, water discharge rate, and sediment depth regulated the stocks and export rates of DC and its components. Forest streams are important links between the carbon biogeochemical cycle of subalpine forests and adjoining streams.

Summary: This study aims to quantify the impact of water erosion on the loss of total organic carbon (OC) and nitrogen (N) in boreal mineral soils under different cultivation practices. The results show that sediment OC and N exports are related to soil plowing and discharge intensity, while dissolved OC loss is promoted by high surface soil OC%. These findings are important for complementing carbon budget estimations and assessing soil management effects on surface water quality.

Summary: The study found that the subsurface DIC maximum layer deepened and expanded northwards into the Makarov Basin during 2008-2015. The increase in DIC concentrations in the Chukchi-East Siberian Shelfbreak and Makarov Basin is mainly attributed to increased local biological degradation and transportation of DIC-rich water from the Chukchi Shelf. Advection was found to control the increase in DIC content in the Makarov Basin, driven by a shift in ocean circulation pattern during 2008-2015.

Summary: The Canadian Arctic is warming at three times the rate of the rest of the planet. This study examines the effects of climate change on the Arctic marine carbon cycle by analyzing stable carbon and radiocarbon values of dissolved inorganic carbon collected in Baffin Bay. The results suggest a residence time of 360-690 years for deep water in Baffin Bay.

Summary: This study investigates the coupling between Chromophoric Dissolved Organic Matter (CDOM) and Dissolved Inorganic Carbon (DIC) in eighteen Indian estuaries. The study reveals a significant linear relationship between DIC, CDOM abundance, and pH level in most estuaries, with some estuaries showing elevated DIC levels and other indicators suggesting anthropogenic influence. CDOM properties, such as spectral slope and spectral slope ratio, align with these findings. The study also finds that CDOM contributes different proportions of DIC in different estuaries, indicating its importance in the organic alkalinity of estuaries.

Summary: This study uses a coupled ocean-sea ice-biogeochemical model to quantify the flux of dissolved inorganic carbon (DIC) from the Chukchi shelf to the deep ocean. It finds that the Pacific inflow is the main driver of the highly efficient continental shelf pump in the Chukchi Sea, exporting an average of 828 Tg C-DIC to deep basins annually during 1998-2015. DIC is mainly exported through Barrow Canyon in summer and along the shelf under the 100 m isobath in winter, influenced by seasonal wind patterns and interannual variability.

Summary: This study analyzed the impact of fertilization changes on crop yields and nutrient runoff in a small agricultural catchment using the SWAT model. Results showed that the annual loads of NO3 and organic phosphorous were relatively low for different crops, while the surface runoff of dissolved Glyphosate was relatively high.

Summary: Since the Industrial Revolution, the atmospheric partial pressure of CO2 has been rapidly increasing, leading to ocean acidification with a decrease in surface ocean pH. In crustaceans, exposure to low pH altered immune markers but did not have a significant impact on fitness parameters.

Summary: The uptake and cycling of atmospheric CO2 in the ocean play a major role in global climate change and carbon cycling. The stable carbon isotope (delta C-13-DIC) of dissolved inorganic carbon (DIC) serves as a valuable tracer for various oceanic processes. This study presents new data on delta C-13-DIC from water samples collected in the western North Pacific Ocean and compares them with previous findings. The results show variations in the delta C-13-DIC values, influenced by air-sea exchange, photosynthesis, water dynamics, and isotopic fractionation. The study also reveals a decline in delta C-13-DIC values over time, indicating the impact of anthropogenic CO2 absorption and water mixing in accelerating this decrease.

Summary: This study examined the carbon flux from artificially-drained cropped fields. The results showed that the dominant carbon export was from inorganic carbon (IC) losses through subsurface drainage tiles. Detailed soil sampling revealed that approximately 0.23% of the total carbon content in shallow soils was lost in a single year. The study suggests the need for improved monitoring of total carbon export from fields for accurate assessment of carbon sequestration.

Summary: Using a data-constrained circulation model, we efficiently computed the steady state distribution of deep ocean dissolved organic carbon (DOC) at a 1 degree horizontal resolution. Our model simulated the total DOC as a sum of two pools and successfully reproduced the large-scale features of deep ocean DOC. The sensitivity of deep ocean DOC to preformed DOC concentrations and other factors were also investigated.

Summary: Spatial and seasonal changes in benthic fluxes of dissolved silica (DSi) were investigated in the southern Baltic Sea. The study found that sediments with high mud content had the highest fluxes in autumn, while sandy sediments showed no clear seasonal patterns. Biological factors were key explanatory variables in shallow enclosed areas, while environmental factors played a larger role in open areas. The study also highlighted the importance of benthic fluxes in the marine Si cycle.

Summary: Biomineralization plays a crucial role in ecosystem functioning and the use of carbonate skeleton as environmental proxies. This study investigated the influence of salinity on mineral type and chemical element concentrations in the skeletons of invertebrates from the Baltic Sea. The results showed that both environmental parameters and biological mechanisms contribute to skeletal formation, and the concentrations of different elements varied between species and with increasing salinity. This study emphasizes the importance of both biological and environmental factors in shaping the composition of calcifying organisms' skeletons.

Summary: This study investigated the spatial variability in hydrography and carbonate chemistry in four Spitsbergen fjords during the high meltwater season. The results showed that the differences in hydrology led to spatial changes in the CO2 system structure. The freshwater input had a diluting effect and lowered the alkalinity in the surface waters of the fjords. The study also highlighted the importance of recognizing the variability in alkalinity and freshwater end-members in predicting marine CO2 system changes.

Summary: The influence of hypoxic submarine groundwater discharge on the carbonate system of coastal seawater is still poorly understood. This study investigates the production of dissolved inorganic carbon and alkalinity in coastal sediments under the impact of oxygen-deficient SGD. It finds that SGD can potentially contribute to ocean acidification and affect the functioning of calcifying invertebrates.

Summary: For thousands of years, humans have been attracted to coastlines for their resource potential and as geopolitical centers. The supply and demand of potable water are crucial for water security in coastal communities, but the interaction between freshwater and saltwater in coastal settings is complicated by natural and human-driven environmental changes. Understanding groundwater fluxes across the land-sea continuum is important for (bio)geochemical budgets and the potential use of offshore freshened groundwater as a resource. Assessing land-ocean connectivity through groundwater requires a multidisciplinary approach and is relevant for climate change, pollution, and sustainable development goals.

Summary: This paper reviews the biogeochemical functioning of the Baltic Sea and its impact on the ecological status. The Baltic Sea has undergone significant changes in recent decades, and the reduction in nutrient loads has not yet resulted in improved oxygen availability due to the low burial efficiency of phosphorus. The assessment also highlights the knowledge gaps and future research needs in marine biogeochemistry in the Baltic Sea.
