Radiocarbon uptake by Thalassiosira pseudonana was used to compare the effect of bottle type on primary productivity. Three types used in primary productivity studies were considered: standard soda‐lime bottles, commercial Pyrex bottles, and quartz bottles. Transmittance within the ultraviolet region (e.g. 290–320 nm) varied significantly (quartz > Pyrex > Wheaton “800” glass). Measurements of radiocarbon uptake in the three bottle types under white fluorescent lamps alone (4.48 W·m −2 [380–700 nml) were not significantly different. However, when combined with the sunlamp/filter system (0.74 W m −2 [290–320 nm]), there was a significant difference in productivity. The environmentally significant ultraviolet portion of the solar spectrum should be considered when culture bottles are selected for in situ primary productivity studies.
