Defining Future Seafloor Mapping Priorities to Inform Shallow Coral Reef Management

This project began in October 2020 and will be completed September 2023.

NCCOS is building a digital inventory of shallow water (up to 40 m) mapping data sets and conducting a data needs assessment for the Coral Reef Conservation Program’s (CRCP) jurisdictional waters. Results from this project will enable CRCP and local management organizations to identify priority locations for seafloor mapping data, which are needed to develop scientific information on the condition of coral reef ecosystems.

Why We Care
Spatial information about the seafloor is critical for natural resource managers. CRCP uses high-quality, comprehensive mapping data to develop scientific information on the condition of coral reef ecosystems and develop spatial tools to help inform management decisions. However, collecting spatial data can be costly, logistically intensive, and time consuming. Coordination among local managers and researchers is needed to avoid duplicating efforts, raise awareness of available mapping data, and target new collections for the highest-priority locations. The information provided by participants is an initial step that will help inform research and monitoring activities to address management needs and maximize opportunities to leverage and complement existing regional efforts.

CRCP has partnered with NCCOS to lead a mapping prioritization effort and data inventory within CRCPs jurisdictional waters. This effort aims to:

      1. Identify the availability of existing data and products, and
      2. Identify priority locations and approaches for future data collection.

What We Propose to Do
From fiscal years 2021–2023, NCCOS will build a digital inventory of relevant shallow water (up to 40 m) mapping data sets and conduct a data needs assessment for each of the CRCP jurisdictions: Puerto Rico, the U.S. Virgin Islands, Hawaii, Florida, Guam, Commonwealth of Northern Mariana Islands, and American Samoa. In FY 2021, this analysis will be focused in shallow coral reef areas surrounding Puerto Rico, the U.S. Virgin Islands, and Florida (Martin County to Dry Tortugas; Figure 1).

To identify priority areas within each jurisdiction, the researchers will use a spatial framework and participatory online tool to solicit input from select local participants (Figure 2). Using methods similar to prioritization efforts elsewhere in the U.S. (i.e., West CONUS Coast, U.S. Caribbean, and Southeast U.S.), the team will combine input to identify areas of high priority for collecting contemporary, high-quality mapping data. Ultimately, this will provide CRCP and local managers with a detailed framework for future mapping management needs to protect, conserve, and restore the nation’s coral reefs. The focus of this effort will support CRCP’s four main pillars of work established to:

      • Increase resilience to climate change,
      • Reduce land-based sources of pollution,
      • Improve fisheries’ sustainability, and
      • Restore viable coral populations.

Benefits of Our Work
CRCP has expressly identified the need to create a mapping data inventory and provide a needs-based framework for future mapping efforts within shallow coral reef areas. Results from this project will benefit local jurisdictional communities, resource agencies, and other participating organizations by: (1) identifying regions of overlapping data needs, (2) promoting coordination among participating organizations, and (3) enabling partners to leverage resources to fill their most pressing data needs and information gaps.

Each cell can be selected and populated with virtual "coins" based on the participants' data needs. The tool also allows the participant to input a justification for why those cells were selected, as well as specific data product needs. Credit: NOAA NCCOS.
