Abstract Employing in situ SCUBA methods a seasonal carbon budget has been established for aLaminaria saccharina population in a Scottish sea-loch. Concurrent studies of photosynthesis, secretion rates, reserve fluctuations and frond growth were undertaken. Net annual production is in excess of 120 g C m−2 yr−1. Over 13% of gross carbon input is released as extracellular secretions (over 30% in autumn) and 40–50% is lost by distal decay, entering detrital food chains. The large concentrations of laminarin, synthesised in summer months, are nearly all lost in autumn-winter distal tissue loss and therefore not available for early spring growth.
