18s data availability?

I am working on a project that involves surveying public 18S SSU rRNA gene datasets for specific taxonomic groups and would like to incorporate EMP data if i can. However, I understand that release 1 is all 16S data, and when I look in the Qiita portal I only see 4 18S projects listed. Is there another place to access 18S data that has been generated as a part of the EMP?

Start with the Qiita portal and the EMP release 1 context described in the issue, checking how 18S SSU rRNA projects are listed and accessed. Done means documenting whether additional EMP-generated 18S data exists and providing its access location, if one is available.
