Short summary

Aerosols are tiny particles in the air, and some of them help form cloud droplets (called cloud condensation nuclei). Most ship measurements focus on only one ocean. To compare aerosols over several oceans, we measured them during a transit voyage of a research ship using the same method. The results show that properties of these particles cannot be represented by a single marine condition. Moreover, they changed widely, depending on where the air came from and the pathway it traveled.
