@clyne - You beat me to the punch here! 
I did a deep dive on the program and came up with a much large list.

For my part, here are a few that I’m a part of:
SY21A-02 - Building blocks for a data informed future: data, tooling, and collaboration
IN31B-0661 - Arraylake: A Cloud Native Data Lake Platform for Earth System Science
