Extends the static Sanctuaries Climate Dashboard with an interactive Shiny interface. The signature view is a swipeable map comparing climatological “then” (1985–2005 reference) to “now” (most recent day-of-year) for each sanctuary; a lower slider steps the comparison through the calendar year. Sanctuary and variable are selectable from the left-hand panel.

The application is packaged as a Docker Compose stack and runs alongside the static dashboard so each absorbs the load it’s best suited for: the static site survives Shiny server downtime, while the Shiny app provides exploration where needed. The same ingestion pipeline feeds the noaa-onms/eco-indicators repository (Copernicus for Sanctuaries), from which derived indicators are generated at monthly cadence.
