Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires. We examined the

Using Optical Water Types to Monitor Changes in Optically Complex Inland and Coastal Waters

Remote Sensing, 2019
The European Space Agency’s Copernicus satellites Sentinel-2 and Sentinel-3 provide observations with high spectral, spatial, and temporal resolution which can be used to monitor inland and coastal waters. Such waters are optically complex, and the

Quantifying methane emissions from Laurentian Great Lakes estuaries using in situ measurements, remote sensing, and machine learning

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Freshwater estuaries are natural contributors to the carbon cycle, including production and emission of methane (CH4), a potent greenhouse gas (GHG); however, estimates of their contribution to global GHG emissions is uncertain. Recent research has identified the potential for quantifying limnetic methane using optical remote sensing coupled ...
