  3. Data Availability

    • “Only profiles with BGC” checkbox for profiles that include at least one supported BGC parameter: dissolved oxygen, chlorophyll, nitrate, backscattering, pH, downwelling irradiance at 490 nm, or PAR
    • Not every BGC parameter has an in-app chart. Downwelling irradiance at 490 nm can be included in search and downloaded profile data, but it is not currently displayed as a chart.

Results and Analysis Limits

Matching profiles appear as map markers; select one to open its details. If a search input is too broad for θ–S Diagram or Clustering, the corresponding Analyze item shows the current count and remains disabled. Narrow the date range or geographic bounds to 500 profiles or fewer. OceanGraph does not sample or split oversized inputs. Requests are also rate-limited; signing in does not increase an endpoint’s request limit.

For guidance on choosing between regional, date-based, WMO ID, and BGC searches, read Finding Argo Float Profiles by Location, Time, and WMO ID in OceanGraph Articles.
