On the Peril of Inferring Phytoplankton Properties from Remote-Sensing Observations

J. Xavier Prochaska, Robert J. Frouin

Since 1978, sensors on remote-sensing satellites have provided global, multi-band images at optical wavelengths to assess ocean color. In parallel, sophisticated radiative transfer…

Safety first: Stability and dissipation of line-tied force-free flux tubes in magnetized coronae

Natalie Rugg, Jens F. Mahlmann, Anatoly Spitkovsky

Magnetized plasma columns and extended magnetic structures with both footpoints anchored to a surface layer are an important building block of astrophysical dissipation models. Cur…
