Updates for Backscatter Submissions

Data submitters: SeaBASS submission requirements for backscatter have been updated with more complete guidance, including new fields and metadata to better track provenance from e.g., Hyper-bb, ECO-bb, HS6, AC-S, etc. New submissions should follow these updated guidelines. However, there will be a phase-in period before they are mandatory.
