Sea to Space Particle Investigation

View Slideshow »
The Sea to Space Particle Investigation aims to improve the accuracy of particle size distribution products gathered from satellite and remote-sensing data. These data contain critical information that can improve our understanding of how Earth's living marine resources and carbon sequestration are responding to rising carbon dioxide levels and climate changes. The field campaign took place from January 24 through February 20, 2017.
