The crustacean is under substantial recreational and commercial fishing pressure in the regions and in some cases within park boundaries. The monitoring program objectives focus on estimating a population level relative density index, frequency of occurrence index, and average size of spiny lobster and using these metrics to assess changes through time. Changes in these metrics can be evaluated after each survey season and with respect to habitat features, physical environment, and management actions.\n\nThis dataset includes data from the following sampling missions:\n\n2019 - Buck Island Reef National Monument and Salt River Bay National Historical Park and Ecological Preserve\n2021 - Virgin Islands National Park\n2021 - Deep-water surveys (100 - 150ft) around St. John, U.S. Virgin Islands as part of a NOAA Cooperative Agreement\n2021 - Deep-water surveys (100 - 150ft) around St. Croix, U.S. Virgin Islands as part of a NOAA Cooperative Agreement\n2022 - Biscayne National Park\n2023 - Dry Tortugas National Park\n2024 - Buck Island Reef National Monument and Salt River Bay National Historical Park and Ecological Preserve\n\nThis release contains three separate data files:\n\n- Site data: Describes site-level information for lobster surveys. It contains count totals summed from the plot-level. In rare circumstances, if insufficient hardbottom was available, only one plot (not the typical two) was conducted at a site. This is documented in the notes column and the PlotNotVisited column in the Plot data.\n\n- Plot data: Describes diver-level observations within their portion(s) of a lobster survey. Each survey site has two plots, where each diver is responsible for surveying one-half of each plot. Thus, there are 4 records for each plot (1A, 1B, 2A, 2B). In rare circumstances, only enough hardbottom existed to conduct a single plot at a site. This is indicated in the notes column.\n\n- Lobster data: Describes size and demographic characteristics for all individual observed lobsters.", "distribution": [{"@type": "dcat:Distribution", "description": "This dataset describes diver-level observations within their portion(s) of a lobster survey.
