Wildfire Aerosol Deposition Likely Amplified a Summertime Arctic Phytoplankton Bloom
Summertime wildfire activity is increasing in boreal forest and tundra ecosystems in the Northern Hemisphere. However, the impact of long range transport and deposition of wildfire aerosols on biogeochemical cycles in the Arctic Ocean is unknown. Here, we use satellite-based ocean color data, atmosp...
