Marine pollution is usually described in visible terms: plastic fragments, oil films, algal blooms, and debris fields. But a growing part of ocean chemistry is visible only to instruments. A recent Nature Geoscience analysis examined anthropogenic chemical signatures in marine dissolved organic matter using public non-targeted tandem mass spectrometry datasets: 21 datasets, 2,315 seawater samples, and coverage across three ocean basins. Instead of testing only for a short list of known pollutants, the researchers searched broadly for molecular features consistent with xenobiotic or human-derived compounds, treating seawater as a high-dimensional chemical system rather than a simple container for familiar contaminants.
