A large-scale linear structure has repeatedly appeared on satellite images of Chagan Lake in winter, which was further verified as being ice ridges in the field investigation. We extracted the length and the angle of the ice ridges from multi-source remote sensing images. The average length was 21 141.57 ± 68.36 m. The average azimuth angle was 335.48° 141.57 ± 0.23°. The evolution of surface morphology is closely associated with air temperature, wind, and shoreline geometry.

During 1984–2018, lakes in the Tibetan-Qinghai Plateau had the clearest water (mean 3.32 ± 0.38 m), while those in the northeastern region had the lowest Secchi disk depth (SDD) (mean 0.60 ± 0.09 m). Among the 10 814 lakes with > 10 years of SDD results, 55.4 % and 3.5 % experienced significantly increasing and decreasing trends of SDD, respectively. With the exception of Inner Mongolia–Xinjiang, more than half of lakes in all the other regions exhibited a significant trend of increasing SDD.

The spatial distribution of the attenuation of photosynthetic active radiation (Kd(PAR)) was routinely estimated in China lakes and reservoirs. The light absorption coefficient of OACs could explain 70 %–87 % of Kd(PAR) variations. Kd(PAR) could be predicted from aOACs values in the inland waters. Besides, results of this study are suggesting that new studies on the variability of Kd(PAR) in inland waters must consider the hydrodynamic conditions, trophic status and OACs within the water column.

Inland lakes are a direct link among the land, atmospheric and oceans (via rivers). Little is currently known about colored dissolved organic matter and its relationship with water quality in lakes across the Tibet Plateau. For these brackish and saline lakes, a high salt content with accumulation of carbon and low organic colored dissolved matter in brackish lakes, indicating the influence of strong evapoconcentration, intense ultraviolet irradiance and landscapes.

CDOM has strong link with DOC, which sets the basis for remote estimation of DOC in waters. However, the relationships between DOC and CDOM absorption for different types of inland waters may vary which worth further systematic investigations. Samples from fresh lakes, saline lakes, rivers, urban water bodies, ice-covered lakes were measured to examine the relationship between DOC and CDOM. The regression model slopes range from 1.03 for urban waters to 3.13 for river water.

Our results of this study show that two humic-like C peaks and two protein-like B and T peaks were identified from CDOM using PARAFAC for investigated lakes. The average fluorescence intensity of the components differed seasonally. Components 1 and 2 exhibited strong linear correlation (R2 = 0.63). Significantly positive linear relationships, between aCDOM and Fmax, and between DOC and salinity (R2 = 0.93), were revealed.

Using daily ice records of 156 hydrological stations across Songhua River Basin, we examined the spatial variability in the river ice phenology and river ice thickness from 2010 to 2015 and explored the role of snow depth and air temperature on the ice thickness. Snow cover correlated with ice thickness significantly and positively when the freshwater was completely frozen. Cumulative air temperature of freezing provides a better predictor than the air temperature for ice thickness modeling.

Short summary
The study indicated that CDOM in rivers had higher aromaticity, molecular weight, and vascular plant contribution than in terminal lakes in the Hulun Buir plateau, Northeast China. The autochthonous sources of CDOM in plateau waters were higher than in other freshwater rivers reported in the literature. Study of the optical–physicochemical correlations is helpful in the evaluation of the potential influence of water quality factors on non-water light absorption in plateau water environments.

Discrete riparian inflow points (DRIPs) transport dissolved organic carbon (DOC) from large areas to discrete sections of streams, yet the mechanisms by which DRIPs affect stream DOC concentration, cycling, and export are still unknown. Here, we tested four models that account for different hydrologic and biological representations to show that DRIPs generally reduce DOC exports by either diluting stream DOC (snowmelt period) or promoting aquatic metabolism (summer).

We applied CoupModel to quantify the impacts of natural and human disturbances to adjacent water bodies in regulating net CO2 uptake of northern peatlands. We found that 1 m drops of the water level at the beaver pond lower the peatland water table depth 250 m away by 0.15 m and reduce the peatland net CO2 uptake by 120 g C m-2 yr-1. Therefore, although bogs are ombrotrophic rainfed systems, the boundary hydrological conditions play an important role in regulating water storage and CO2 uptake.

Stable isotope ratios (isotope values) of surface water reflect hydrological pathways, mixing processes, and atmospheric exchange within catchments. We used a water-balance-based mapping method, which represents patterns of surface flow and mixing, and added a regression-based correction step using catchment environmental characteristics to map water isotope ratios across all the rivers of New Zealand.

We introduce a new multi-process river sediment module for Earth system models. Application and validation over the contiguous US indicate a satisfactory model performance over large river systems, including those heavily regulated by reservoirs. This new sediment module enables future modeling of the transportation and transformation of carbon and nutrients carried by the fine sediment along the river–ocean continuum to close the global carbon and nutrient cycles.

Peatlands are a major stock of carbon that can be released as dissolved organic carbon (DOC), affecting carbon balance and downstream water quality. This study investigates the impact of peatland restoration on water balance and DOC exports using a simple modelling approach. The results suggest that the restoration can affect the water balance and the dynamics of DOC in the peatland. However, there is no major impact in the quantity of DOC released in a short-term period (3 years).

We summarize our findings as follows: (1) the mountain watersheds are vulnerable to agriculture expansion; (2) proper spatial configuration of agricultural lands in mountain watersheds can mitigate the impact of agriculture on NO3- output by 70%; and (3) the reconstructed element fluxes for the watersheds indicate excessive leaching of N and P, and additional loss of N to the atmosphere via volatilization and denitrification, which likely resulted from excessive fertilizer use.
