01 / DATA PROVENANCE
Trace every layer
Provider, dataset, licence, spatial resolution, time coverage and retrieval time are retained separately.
SCIENCE & METHODOLOGY / V1.0
Trust is built into the method.
A useful ocean platform must show what is known, how it is known and where the evidence ends.
Measure first.
Act second.
Verify everything.
Act second.
Verify everything.
02 / REPRESENTATION
Imagery is not a point measurement
NASA GIBS serves visualisations. Happy Orbis does not reverse-engineer colour into precise numerical values. Missing or transparent pixels must not be interpreted as zero.
03 / TIME & COMPARISON
Compare like with like
Compare the same product and season where possible. Date comparison shows two imagery snapshots, not a statistically tested trend. MUR25 anomalies use the provider’s 2003–2014 climatology.
04 / UNCERTAINTY
Keep the categories separate
Observed profiles, satellite retrievals, interpolated analyses and forecasts have different uncertainty.
05 / INTELLIGENCE
Source-based guidance
The current evidence guide uses curated source explanations and map actions.
06 / VERIFICATION
No result without evidence
An intervention must retain its baseline, location, time, methodology, supporting records and reviewer. Estimated, measured and independently verified outcomes remain separate.
