Sažetak
The dry matter and ash-free dry matter (DW, AFDW), the particulate organic carbon (POC), and the particulate organic nitrogen (PON) content of suspended mucous aggregates and seston were determined in the Gulf of Trieste during the 1997 (July-August) mucilage event. Seston was sampled with 5L Niskin bottles while mucous aggregates were collected by SCUBA divers using a peristaltic mucous aggregates was estimated on the basis of in situ SCUBA diver observertions, photography, and video-recording of vertical profiles of their sizes, types and abundances. Organic seston (AFDW) concentration varied from 1.2 to 2.6 mg/L, which was within the normal range for the summer period. The concentration of organic matter associated with mucious aggregates (0.2 to 6.1 mg/L) contributed significantly to the total suspended organic matter indicating that a significant part of primary production was channeled into mucilage. It was estimated that during 2 mounth period about 40 percent of the total primary production accumulated as C-rich (C/N ratio 9.8-18.0) mucilage organic matter.
