“…Lake Erie is one of the water bodies that have been suffering water quality issues such as harmful algal blooms (HABs) and hypoxia due to excessive nutrient loading from large agricultural fields (part of the corn belt) distributed in its drainage areas (Fig. 1 and Table 1 ) 7 , 16 , 23 – 25 . The West Lake Erie basin is known as the largest source of nutrients transported to the lake in particulate and dissolved forms 26 , 27 .…”

Soluble nitrogen is highly mobile in soil and susceptible to leaching. It is important to identify nitrogen transport pathways so that the sources can be efficiently targeted in environment management. This study quantified the contribution of direct runoff and baseflow to nitrate + nitrite loading by separating flow and nitrate + nitrite concentration measurements into two periods depending on whether only baseflow was present or not using baseflow separation methods. When both direct runoff and baseflow were present in streamflow, their nitrate + nitrite concentrations were assumed based on the hydrological reasoning that baseflow does not change rapidly, and streamflow mostly consists of direct runoff within a rainfall event. For this study, we obtained and investigated daily flow and nitrate + nitrite concentration observations made at the outlets of 22 watersheds located in the Western Lake Erie area. Results showed that baseflow was responsible for 26 to 77% of the nitrate + nitrite loads. The relative nitrate + nitrite load contributions of direct runoff and baseflow substantially varied with the sizes of drainage areas and agricultural land uses. Increases in drainage areas tend to prolong the travel time of surface runoff and thus help its reinfiltration into soil, which then could increase the baseflow contribution. In addition, the artificial drainage networks common in the agricultural fields of the study areas would promote the drainage of nutrient-laden excess water from soils. Such findings suggest the need for environmental management customized considering nitrogen transport pathways.

“…Satellite images show the turbidity that characterizes its waters, and at its mouth, large chlorophyll plumes often form due to the river's discharge [30]. − Lake Erie (Figure 1b) constitutes the shallowest of the Great Lakes and is surrounded by Canada and the states of New York, Pennsylvania, Michigan, and Ohio in the U.S. [31]. The UAV survey was conducted over the Western Lake Erie Basin, from Michigan (41 • 49 ′ 45.66 ′′ N; 83 • 24 ′ 34.12 ′′ W).…”

Aquatic ecosystems are crucial in preserving biodiversity, regulating biogeochemical cycles, and sustaining human life; however, their resilience against climate change and anthropogenic stressors remains poorly understood. Recently, unmanned aerial vehicles (UAVs) have become a vital monitoring tool, bridging the gap between satellite imagery and ground-based observations in coastal and marine environments with high spatial resolution. The dynamic nature of water surfaces poses a challenge for photogrammetric techniques due to the absence of fixed reference points. Addressing these issues, this study introduces an innovative, efficient, and accurate workflow for georeferencing and mosaicking that overcomes previous limitations. Using open-source Python libraries, this workflow employs direct georeferencing to produce a georeferenced orthomosaic that integrates multiple UAV captures, and this has been tested in multiple locations worldwide with optical RGB, thermal, and multispectral imagery. The best case achieved a Root Mean Square Error of 4.52 m and a standard deviation of 2.51 m for georeferencing accuracy, thus preserving the UAV’s centimeter-scale spatial resolution. This open-source workflow represents a significant advancement in the monitoring of marine and coastal processes, resolving a major limitation facing UAV technology in the remote observation of local-scale phenomena over water surfaces.

“…This parameter serves as an indicator of the potential pool of nutrients, particularly nitrogen, which can be mineralized to become available for plant uptake. Essentially, it provides a tangible measure of the microbial life present in the soil and its potential contribution to soil fertility [20]. Lastly, one of the techniques that have significantly expanded our understanding of nutrient cycles in soil ecosystems is isotope tracing.…”

Soil a significant carbon sink, plays a pivotal role in mitigating climate change. This review underscores the potential of soil amendments for enhancing carbon sequestration, focusing on the intricate relationship between these amendments and soil microbial communities. Soil amendments, ranging from biochar and organic compost to mineral additives, have been identified as viable strategies to boost soil carbon stocks. Concurrently, these amendments influence the diversity, structure, and functional roles of microbial communities, which in turn, are integral to soil carbon dynamics. Tools like 16S rRNA sequencing, metagenomics, and isotope tracing techniques have propelled our understanding of microbial responses, shedding light on the complex microbial networks and their roles in carbon cycling. While promising, the application of soil amendments presents challenges. Variability arising from different soil types, climates, and microbial dynamics poses a consistent research challenge. Potential risks like reduced sequestration over time and economic considerations for large-scale application necessitate attention. Future directions hinge on innovations in soil amendment products, harnessing microbial inoculants for synergistic effects, and fostering interdisciplinary collaborations. This convergence of science, technology, and collaborative research heralds a future where soils are not just seen as substrates but as active, dynamic entities in the fight against climate change.
