View Resource How do Lake Ecosystems Change with Increases in Dissolved Organic Matter (DOM) and Reduced Water Clarity? Long-term investigations in lake ecology

Water quality is a significant issue affecting our lakes. While the effects of nutrients on water quality has received much attention, light availability also has strong effects on water quality in lake ecosystems. Light availability has been changing in many lakes with changes in water clarity. Many lakes are undergoing “browning”, where waters become darker and less transparent due to increases...
