Impact of environmental seasonality on stable isotope composition of skeletons of the temperate bryozoan Cellaria sinuosa

Cellaria sinuosa shows an age of 1.5 years with an annual growth rate of approximately 32 mm/yr. Carbonate production by C. sinuosa on the shelf off Roscoff varies between 12 gr/m2/yr and 57 gr/m2/yr and lies within the range of cold-water carbonates.
