Description:The purpose of this technical memorandum is to describe the National Centers for Coastal Ocean Science’s (NCCOS) best practices for collecting, processing, and analyzing lakebed ground-truthing and accuracy assessment data (underwater photos/videos or sediment samples) required to develop lakebed maps in the Great Lakes. These practices have been refined over years of data collection efforts by NCCOS across various study areas distributed throughout the Great Lakes and marine waters (Costa et al. 2009, Kendall et al. 2017, Menza et al. 2019, Battista et al. 2019). For this report, we use a 2021 mapping project offshore of the Bayfield Peninsula and Apostle Islands National Lakeshore (APIS) in Lake Superior, Wisconsin, as a case study to describe best practices. This memorandum will immediately support mapping project partners with information needed to collect, process and analyze ground-truthing and accuracy assessment data. It will also be useful to other projects and offices mapping in the Great Lakes with the Coastal and Marine Ecological Classification Standard (CMECS) or other classification systems.
