dc.description.abstract | Ocean acidification (OA) is the reduction in seawater pH due to the absorption of human-released
CO 2 by the world’s oceans. The average surface oceanic pH is predicted to decline by 0.4 units by
2100. However, kelp metabolically modifies seawater pH via photosynthesis and respiration in some
temperate coastal systems, resulting in daily pH fluctuations of up to ±0.45 units. It is unknown how
these fluctuations in pH influence the growth and physiology of the kelp, or how this might change
with OA. In laboratory experiments that mimicked the most extreme pH fluctuations measured within
beds of the canopy-forming kelp Ecklonia radiata in Tasmania, the growth and photosynthetic rates
of juvenile E. radiata were greater under fluctuating pH (8.4 in the day, 7.8 at night) than in static pH
treatments (8.4, 8.1, 7.8). However, pH fluctuations had no effect on growth rates and a negative
effect on photosynthesis when the mean pH of each treatment was reduced by 0.3 units. Currently, pH
fluctuations have a positive effect on E. radiata but this effect could be reversed in the future under OA,
which is likely to impact the future ecological dynamics and productivity of habitats dominated by E.
