    "body_text": "Researchers tested an outdoor open-vocabulary 3D scene-graph method in maritime environments and found that it described many geometry-supported objects but fragmented single physical entities and imposed terrestrial spatial assumptions. Their adaptation consolidates accumulated metric and semantic evidence, uses geometry-grounded multiview reasoning to reconcile fragments, and builds maritime macro regions from map priors and onboard observations. The resulting representation reduced entity fragmentation and improved reviewed contextual-retrieval queries over tested baselines. It is a mapping adaptation for the reported data, not proof of general marine autonomy.",
