The Society for American Archaeology is currently revising their Principles of Archaeological Ethics and looking for input from archaeologists. Information about the process is here: https://www.saa.org/quick-nav/saa-media-room/saa-news/2020/04/22/take-the-saa-archaeological-ethics-survey 

They want to hear not just from SAA members, but others as well. You'll find the survey here: https://unf.co1.qualtrics.com/jfe/form/SV_aeEvnYOYCFKw5Df
