About this Map
Overview
This map was developed by a research team at Oregon State University to visualize survey responses on subjective human well-being in the Puget Sound in 2018 and 2020. The two human well-being indicators shown in this map are reported frequency of individual shellfish harvests and reported race, shown as overlays to shellfish harvest closures in the Puget Sound.
The purpose of this map is to identify locations and times that may have implications for environmental justice -- through the intersection of frequent harvesters, non-white populations, and high-duration shellfish harvest closures.
The map displays circles wherever a shellfish harvest closure occurred in the Puget Sound between 2017-2020. Circles are sized by the duration of each closure (% of days closed per month).
Charts shown in the panel are synchronized with the map and will dynamically update by panning around or zooming in or out on the map. Chart counts are recalculated based on harvest closures that are visible in the current map filter.
Overlay layers
Frequent Harvesters - Interpolated survey responses to the question: "In the past year, about how often did you hunt, harvest, gather, or forage for shellfish in the Puget Sound Region?" Answer choices: 1 = Never; 2 = Rarely (1-2 times a season); 3 = Occasionally (3-5 times a season); 4 = Regularly (6-8 times a season); or 5 = Frequently (More than 10 times a season). Frequent harvester responses are visualized in red. The 2020 survey responses reflect harvest frequencies for bivalve shellfish only (e.g. clams, oysters, mussels).
People of Color - Interpolated survey responses to the question: "What is your race? Mark all that apply." Answer choices: Black or African American; Native American or Native Alaskan; Native Hawaiian or Other Pacific Islander; Asian; White; Hispanic or Latino; and Other. Non-white responses are visualized in blue.
Dynamic features
Time slider chart - A count of shellfish harvest closures per month is shown in a dynamic time chart. You can click, drag, and slide a window of time to filter out only the harvest closures that fall within the time(s) selected. Panning around or zooming in or out on the map will automatically update the count of harvest closures per month shown on the chart.
Closure type chart - A count of shellfish harvest closures by their closure type is displayed in a dynamic bar chart. You can click on any of the bars to filter out only the closure type(s) that fall within the type(s) selected. Panning around or zooming in or out on the map will automatically update the count of harvest closures per closure type being shown on the chart.
Closure duration chart - A count of shellfish harvest closures by duration is displayed in a dynamic bar chart. You can click on any of the bars to filter out only the closures that fall within the duration(s) selected. Panning around or zooming in or out on the map will automatically update the count of harvest closures per duration being shown on the chart.
Area type chart - A count of shellfish harvest closures by area type is displayed in a dynamic bar chart. You can click on any of the bars to filter out only the closures that fall within the area type(s) selected. Panning around or zooming in or out on the map will automatically update the count of harvest closures per area type being shown on the chart.
County chart - A count of shellfish harvest closures by county is displayed in a dynamic bar chart. You can click on any of the bars to filter out only the closures that fall within the area type(s) selected. Panning around or zooming in or out on the map will automatically update the count of harvest closures per county being shown on the chart.
