Nitrifying microorganisms, including ammonia-oxidizing archaea, ammonia-oxidizing bacteria, and nitrite-oxidizing bacteria, are the most abundant chemoautotrophs in the ocean and play an important role in the global carbon cycle by fixing d...
Diazotrophy modulates cyanobacteria stoichiometry through functional traits that determine bloom magnitude and toxin production [0.03%]

Harmful cyanobacterial blooms are an increasing threat to water quality. The interactions between two eco-physiological functional traits of cyanobacteria, diazotrophy (nitrogen (N)-fixation) and N-rich cyanotoxin synthesis, have never been...
Emerging harmful algal blooms caused by distinct seasonal assemblages of a toxic diatom [0.03%]

Shallow coastal waters are dynamic environments that dominate global marine methane emissions. Particularly high methane concentrations are found in seasonally anoxic waters, which are spreading in eutrophic coastal systems, potentially lea...
The influence of particle concentration and bulk characteristics on polarized oceanographic lidar measurements [0.03%]
