Driving Mechanism of Spring-Algal-Bloom in Lakes Freeze-Thaw Processes
Lakes are important carriers of surface water resources, playing a role in protecting biodiversity, maintaining ecological balance within the watershed, and supplying fresh water. The migration pathways and rates of nitrogen and phosphorus nutrients to lakes have exhibited diversity and variability under the dual pressure of global warming and human activities. The algal blooms in mid- to high-latitude lakes are facing challenges such as earlier outbreak times, longer duration, and increased frequency of occurrence. Previous studies have found that the presence of freeze-thaw processes is the key to promoting the mechanism of algal blooms in mid- to high-latitude lakes, which is different from that in low-latitude lakes. Hence, how to reveal the impact mechanism of freeze-thaw processes on the occurrence and development of spring algal blooms is crucial for water-environment management.

Layers of Paint for the Exterior
The number of layers needed can also depend on the quality and type of paint used. High-quality exterior paints often require fewer coats to achieve full coverage and durability. Acrylic paints, for example, are known for their excellent adhesion and weather resistance, often resulting in a smoother finish with fewer layers.
