The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | NCCOS Mapping: Collaborative Benthic Habitat Mapping in the Nearshore Waters of the Great Lakes Basin – Collection locations of GL-24-01 cruise benthic imagery and sediment samples in the Wisconsin Shipwreck Coast National Marine Sanctuary (WSCNMS) Lake Michigan, 2024-04-30 to 2024-10-16 (NCEI Accession 0306219) |
| Abstract: | This dataset includes collection locations associated with sites sampled throughout the Wisconsin Shipwreck Coast National Marine Sanctuary (WSCNMS). Site information data was collected by a series of sampling platforms including, a Drop Camera, a Remotely Operated Vehicle (ROV), an Autonomous Operated Vehicle (AUV) and a Ponar sediment sampler. The benthic imagery was collected in 2024 in southwestern Lake Michigan throughout the Wisconsin Shipwreck Coast National Marine Sanctuary (WSCNMS) to characterize the lakebed and provide ground-truthing observation data for predictive substrate and biological community models. This dataset includes supplementary data used in planning the collection, including the planned sampling sites and environmental covariates used in sampling site allocation; including, but not limited to, latitude and longitude coordinates at each sample site, maximum sampling depth in meters and duration time of bottom sample. The dataset includes collection locations to be referenced in a cruise report. |

| Supplementary information: | Collection methods for benthic and sediment sample imagery is described in Cruise Report: Great Lakes Benthic Characterization Cruise GL-24-01, May 2024-October 2024 (DOI TBD). All data were gathered in the field at the time of collection using the ArcGIS Survey 123 application. The entirety of benthic videos collected by drop cameras were sent to and processed in TATOR, an online cloud-based video management and annotation system developed by CVision AI., Inc. For benthic images collected by the USGS IVER AUV, only images within 10 m of planned sites were sent to TATOR for further processing. Videos were synchronized to positional data collected by an ultrashort baseline system so that each video frame could receive an underwater spatial coordinate. Then, individual video frames were selected every 10 m for annotation. Each selected frame was annotated by a benthic mapping matter expert. Annotations included the percent cover of substrates and biological cover, benthic organism abundance, and geomorphological characteristics. Lakebed measurements and benthic characterization labels were classified according to the Coastal and Marine Ecological Classification Standard (CMECS; FGDC 2012). |
