Widespread global increase in intense lake phytoplankton blooms since the 1980s
TL;DR: Three decades of high-resolution Landsat 5 satellite imagery are used to investigate long-term trends in intense summertime near-surface phytoplankton blooms for 71 large lakes globally, revealing a worldwide exacerbation of bloom conditions.

TL;DR: The United States (U.S.) federal government provides imagery obtained by federally funded Earth Observation satellites typically at no cost, until 2008 when the United States Geological Survey (USGS) made Landsat data accessible via the internet for free as mentioned in this paper.
Journal ArticleDOI
Seamless retrievals of chlorophyll-a from Sentinel-2 (MSI) and Sentinel-3 (OLCI) in inland and coastal waters: A machine-learning approach
Nima Pahlevan,Brandon I Smith,John F. Schalles,Caren Binding,Zhigang Cao,Ronghua Ma,Krista Alikas,Kersti Kangro,Daniela Gurlin,Nguyen Thi Thu Ha,Bunkei Matsushita,Wesley J. Moses,Steven Greb,Moritz K. Lehmann,Michael Ondrusek,Natascha Oppelt,Richard P. Stumpf +16 more
TL;DR: In this paper, a machine-learning model, the Mixture Density Network (MDN), was proposed for consistent, cross-mission retrievals of near-surface concentration of chlorophyll-a (Chla) in various aquatic ecosystems with broad ranges of trophic levels.
Journal ArticleDOI
Sentinel-2 MultiSpectral Instrument (MSI) data processing for aquatic science applications: Demonstrations and validations
Nima Pahlevan,S. Sarkar,Bryan A. Franz,Sundarabalan V. Balasubramanian,Sundarabalan V. Balasubramanian,Jiaying He +5 more
TL;DR: The European Space Agency's Sentinel-2A mission with the MultiSpectral Instrument (MSI) onboard was launched in 2015, initiating a new era in high-to-moderate-resolution (i.e., 10 to 60m) imaging of Earth's resources as discussed by the authors.
