Analyzing Sources of Pollution in the Great Lakes
Understanding how agriculture and land use affect nutrient flows and concentrations in the vast area of the Great Lakes is an essential step to developing sustainable management strategies.
High-Frequency Monitoring Reveals Riverine Nitrogen Removal
Years of daily readings provide an unprecedented view into how a submerged aquatic meadow kept nitrogen from reaching the St. Lawrence Estuary as well as insights on how climate change may alter it.
Harmful Algal Blooms: No Good, Just the Bad and the Ugly
Natural and human factors are leading to larger, more frequent, and longer-lasting algae blooms. Recent research is increasingly revealing the scope of the problem and informing potential responses.
A New Technique Could Identify Algae from Space
Some types of algal blooms produce dangerous toxins, while others are relatively harmless to humans.
Cyanobacteria Blooms Exceed WHO Thresholds in Midwest Lakes
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
Remote Sensing of Algal Blooms Can Improve Health and Save Money
Using satellites to detect cyanobacterial algal blooms can foster faster decision-making that reduces harm to public health as well as associated costs.
Stored Nutrients and Climate Warming Will Feed More Algal Blooms
High nutrient concentrations cause water quality problems in lakes, and as the climate warms, these issues will only get worse. A new model assesses future scenarios and explores solutions.
Toxic Algal Blooms Are Worsening with Climate Change
Researchers use remote sensing technology to carry out a global survey of large freshwater lakes.
Mapping Ice Algal Blooms from Space
Satellite data reveal how colorful algae are melting the Greenland ice sheet.
