Open data from the current IMWO archive.

Each row is one source-channel record. Multilateral-bank project rows are financed-project candidates. EIB rows merge its complete public financed-project and pipeline lists by eight-digit project ID: the 17,103-project cycle yields 1,611 screened marine and water candidates, including every record officially classified in Water, sewerage. A listed promoter is not a contractor, supplier, winner or subcontractor, and EIB financing is not project cost or contract value. World Bank IPF contract-award rows add official parent project, supplier and committed-value reporting but exclude subcontract awards and cofinancing. Procurement rows are merged where official identifiers permit it. USAspending subaward fields reproduce linked federal reporting without converting a reported subrecipient into an IMWO-verified delivery party. AusTender rows combine six official annual resources for 2014-15 through 2019-20 with incremental OCDS API coverage, retaining Australian Government buyers, awarded suppliers and disclosed AUD values without asserting subcontractors, completion or annual spend. Buy NSW rows add state-government contracting agencies, named contractors and disclosed AUD values from eight official annual notice reports. Queensland State rows scan statewide historical disclosures and current water, waterways, reconstruction, environment, development and pumped-hydro CKAN DataStore resources for physical marine and water contract awards. Queensland TMR rows add six annual CKAN DataStore resources for physical marine contract awards, with contractors and AUD values retained but no inference of subcontractors, progress, acceptance or actual expenditure. Tenders WA rows add 104 Western Australian physical marine awards from 23 targeted official-title searches and adaptive date splitting. Los Angeles RAMP rows add physical marine and water opportunity awards and open bids while keeping strongly resolved primary awardees separate from other or role-unresolved award participants; the latter are not labeled as subcontractors without independent evidence. UNOPS rows add annual 2018-2026 purchase-order and tender coverage while retaining a named purchase-order supplier only in that source-reported role. Repeated rows are grouped by purchase-order identifier, published row amounts are never summed or described as contract totals, and tender records receive no inferred awardee. Discovery rows remain leads until the physical asset, scope, parties, current phase and supporting sources have been independently confirmed.

The searchable project-family layer contains 3,885 institution-separated families across World Bank, ADB, IDB, AfDB, AIIB, EIB and EBRD. Official project IDs control project-level grouping; World Bank and IDB packages link only through exact parent IDs. Otherwise-unlinked ADB awards group only on exact official project name plus country, with ambiguous names left unresolved. No fuzzy entity merge is published. Supplier counts cover linked discovery rows, and aggregated USD values appear only for relevant World Bank signed-contract rows.

Each row is one current public project record. Multi-value fields use semicolon separators; each material-change entry uses pipes for its date, title, impact and source URL. Evidence Reviewed gives the latest source review date; each material development carries its own event date and source.

Event fields describe the dated source record. Current fields provide the project's latest known context and do not backdate that status onto an earlier event. Controlling-source fields identify the evidence used for each row.

Each row is one public organization profile. Multi-value fields use semicolon separators. Last checked gives the most recent source review date; linked projects and marine-work roles show the basis for inclusion.

Each row is one public brief. Published and updated dates describe the IMWO record; source dates remain separate and do not imply a project milestone. Multi-value project and source fields use semicolon separators.

Each row is one monitored URL assignment within a source group. Citing-record fields contain only public IMWO records that use that exact URL; blank citation fields mean the route is monitored but not currently cited. Multi-value fields use semicolon separators.

Each row is one public evidence record. Confirmed evidence and not-yet-verified fields preserve the stated evidence boundary; a record does not constitute certification, ranking, safety approval, or recognition.
