In seawater, we find higher combined carbohydrates (CCHO) in both the particulate (PCCHO, 13–248 μg L–1) and dissolved (DCCHO, 14–294 μg L–1) phases than dissolved free carbohydrates (DFCHO, 1.0–17 μg L–1). Moderate enrichment factors are found in the SML samples (median EFSML = 1.4 for PCCHO, DCCHO, and DFCHO). In PM10 atmospheric particles, combined carbohydrates (CCHOaer,PM10 0.2–11.3 ng m–3) were preferably found in particles of two size modes (0.05–0.42 and 1.2–10 μm) and strongly correlated with Na+aer,PM10 and wind speed, hence suggesting oceanic emission as their primary source. In contrast to SML samples, very high enrichment factors for CCHOaer relative to the bulk water (EFaer) were estimated for supermicron (20–4000) and submicron (40–167 000) particles.
