In early 2020, scientists gathered to advance sediment budget modeling efforts by conducting a “Needs Assessment Workshop” for the Gulf Island National Seashore (GINS) to understand the coastal processes affecting island resiliency. The “Gulf Islands Sediment Budget Needs Assessment Workshop” was held, virtually, April 23–24 and May 27–28, 2020. The workshop series was organized by researchers from North Carolina State University in collaboration with National Park Service (NPS) and U.S. Geological Survey (USGS) staff and was facilitated by personnel from the National Oceanographic and Atmospheric Administration (NOAA). The final survey/questionnaire results are available as American Standard Code for Information Interchange (ASCII) delimited text files in comma-separated values (CSV) and Microsoft Excel (XLSX) file formats. This data release (Forde and Flocks, 2022) includes quantitative (GNIS_Survey_Data_April_Raw.csv, GNIS_Survey_Data_May_Raw.csv) and qualitative (GNIS_Survey_Data_Text_April_Raw.csv, GNIS_Survey_Data_Text_May_Raw.csv) survey results from two questionnaires submitted to attendees during the 2020 GINS sediment budget workshop. For additional information pertaining to workshop details and results, refer to the associated USGS Open-File Report (Seekamp and others, 2022).
