Accessing MBON data
Discover and access marine biodiversity datasets from across the MBON network — observations published openly to OBIS, GBIF, EDI, and ERDDAP, reachable through portals, apps, and code.
Three ways into the data
MBON observations are published openly to global repositories and reached through the network's Tools — pick the on-ramp that fits your work.
Search & download
Discover datasets, map occurrences, and download records through interactive portals like the MBON Data Portal, OBIS, and GBIF.

Dashboards and apps turn raw observations into seascapes, indicators, and decision-ready views — no code required.
Browse appsQuery & analyze
R and Python packages pull data programmatically from OBIS, GBIF, ERDDAP, and more for reproducible analysis.

Harvested from OBIS, GBIF, EDI, and ERDDAP. The same dataset is often mirrored across portals — we list the OBIS record when available, since it carries richer Darwin Core extensions and QA/QC. Filter by portal, method, region, or organization; every card links back to its source.

MBON observations are standardized to Darwin Core and published to open repositories so they are Findable, Accessible, Interoperable, and Reusable. The Ocean Biodiversity Information System (OBIS) is the primary home for biological occurrence data; GBIF aggregates the broader OBIS network; the Environmental Data Initiative (EDI) archives long-term ecological packages; and ERDDAP servers stream gridded and sensor data.
