SOfish Diversity

Explore the fish diversity of the Southern Ocean — filter, map, and analyse occurrence data enriched with taxonomy and biological traits.

What this app does

Tab	Purpose
Display	Interactive occurrence map — colour and size points by family, IUCN status, vulnerability, and more
Filters	Narrow records by taxonomy, body size, depth, ecology, conservation status, commercial traits, and record metadata
Active Filters	Review what filters are currently applied and how many records and species remain
Table	Browse and download the filtered occurrence dataset as CSV
Spatial Diversity	Diversity indicators (Shannon, Simpson, ES50, Hill numbers) overall and broken down by MEASO region
Temporal Diversity	Moving-average diversity trends over time, with sampling effort overlay
Spatial H3 Polygons	Hexagonal grid map of spatial diversity at any H3 resolution

Quick start

Open the Filters tab and select a taxon (e.g. a family or order) to scope the dataset.
Switch to Display to see matching occurrences on the map. Optionally draw a polygon to restrict results to a custom area.
Explore the Spatial Diversity and Temporal Diversity tabs to analyse patterns in your filtered data.
Download any table as CSV using the buttons within each tab.
