CO2 availability in oceans and climate change impacts

I learned through research that increasing levels of atmospheric CO2 was increasing the acidity level of ocean waters.

Can anyone explain in a simple manner what is Fourier shell correlation (FSC)? And how is the conversion from 1D to 3D FSC?

3D FSC curves are used to show directional isotropy and global resolutions in cryo-EM maps. I am having a difficulty to understand the graphs since I do not have absolute clear idea about 3D FSC and sphericity in cryo-EM reconstruction. Attaching with this the DOI to the paper I am trying to understand. doi:10.1038/nmeth.4347, nature […]
