Summary: This study applies remote sensing to monitor long-term chlorophyll-a (Chl-a) concentrations and the trophic state index (TSI) in Lake Burdur, Turkey. Surface reflectances from Landsat satellite images are analyzed to estimate a 38-year time series of Chl-a concentrations. The results show variations in Chl-a concentrations over time, with higher concentrations in 2010 and 2021 and lower concentrations between 1991 and 1993. The TSI values suggest Lake Burdur has been mostly hypertrophic throughout the study period.

Summary: With climate warming and intensification of human activities, the problem of Cladophora blooms in Qinghai Lake, China's largest inland saltwater lake, has become increasingly prominent. This study used remote sensing images to extract the area of floating Cladophora blooms from 1986 to 2021 and analyzed their variation characteristics and spatial patterns. The results showed a general increasing trend of Cladophora blooms in Qinghai Lake, with the largest increase in July. The areas of blooms increased significantly in certain regions, while decreasing in others. The correlation between meteorological factors and the changes in blooms was weak. The control measures implemented in recent years have had a certain inhibitory effect on the blooms.

Summary: Quantum yield of fluorescence (OF) is crucial for understanding the impact of photochemical quenching (PQ) and non-photochemical quenching (NPQ) on sun-induced fluorescence (SIF) signals. However, obtaining accurate OF measurements is challenging due to its high temporal and physiological variability, as well as the need for combined measurements. In this study, we used in-situ measurements in Lake Geneva to investigate the vertical and temporal changes in OF and determine NPQ and PQ conditions. Our findings reveal the presence of NPQ in daytime profiles and the significant influence of downwelling irradiance on OF.

Summary: In alkaline freshwater systems, bicarbonates can support gross primary production (GPP) even at low CO2 concentrations. However, the contribution of bicarbonates to GPP in lakes has not been quantified throughout the seasons. This study analyzes the daily stoichiometric ratios of CO2-O-2 and alkalinity-O-2 in a deep hardwater lake, revealing that alkalinity is the dominant inorganic carbon source for GPP in both littoral and pelagic environments during the stratified period.

Summary: The long-term effects of climate change on lakes globally include substantial changes in thermal regime and oxygen solubility, which can alter ecosystem processes, habitats, and substance concentrations. Although long-term model projections of climate change effects on lakes have been developed, they are rarely compared with multi-decade observations. Additionally, global-scale forcing parameters in lake models have limitations that require significant downscaling. In this study, the effects of climate change on thermal regime and oxygen solubility were analyzed in the four largest French peri-alpine lakes over a period of 1850-2100. The results indicate a critical alteration in lake thermal and oxygen conditions in the coming decades and underscore the need for better integration of long-term lake observatories data and lake models to anticipate climate effects on lake thermal regimes and habitats.

Summary: This study focuses on the seasonality of lateral transport induced by thermal siphons (TSs) and investigates how seasonally varying forcing conditions control the occurrence and intensity of TSs. Observations from Rotsee, a wind-sheltered temperate lake, show that TSs occur frequently in autumn and efficiently flush the littoral region. The results also reveal a decrease in lateral transport by a factor of 2 due to seasonal changes, and the timing of TSs relates to daily heating and cooling phases.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
