Topography and morphology analysis of marine nanoparticles and a pedagogical study of representations used for improving a high school experiment
The Arctic Summer Cloud Ocean Study expedition took place during the autumn of 2008 and brought back water and air samples. One theory was that marine particles were shot into the atmosphere by bubble bursting and, while in the atmosphere, acted as cloud condensation nuclei. Particles collected from...

The Arctic Summer Cloud Ocean Study expedition took place during the autumn of 2008 and brought back water and air samples.
