Do you manage submerged resources, but you’re not an underwater archaeologist? Are you a land-based professional looking to broaden your skill set and knowledge of cultural resources? Do you just want to know what all the diving fuss is about? Land managers, archaeologists, cultural resources specialists, and historic preservation professionals are often tasked with managing, interpreting, and reviewing archaeological assessments of submerged cultural resources. This seminar, which is designed to introduce non-specialists to issues specific to underwater archaeology, is primarily focused on North America but also offers case studies from Europe. Participants will learn about different types of underwater cultural heritage (UCH) and some of the methods employed to help protect those sites. This seminar is not intended to teach participants how to do underwater archaeology, but instead will briefly introduce different investigative techniques and international best practices. The purpose of this seminar is to assist non-specialists in recognizing the potential for UCH resources in their areas of impact. Come find out what waits in the deep and what to do about it!  Objectives: Help terrestrial archaeologists and land managers to: 1) Identify the potential for underwater cultural heritage resources in affected areas; 2) Recognize best practices for treatment of underwater cultural heritage; and 3) Understand basic qualifications required for proper documentation of underwater cultural heritage.
