“…Similar to massive Porites spp., previously we have shown that calcification of P. damicornis in Moorea is resistant to pCO 2 , at least over 15 days of incubations [12]. It has also been reported from mesocosm experiments that OA does not affect settlement of P. damicornis larvae released from adult colonies maintained in acidified conditions [50].…”

Pacific-wide contrast highlights resistance of reef calcifiers to ocean acidification

Ocean acidification (OA) and its associated decline in calcium carbonate saturation states is one of the major threats that tropical coral reefs face this century. Previous studies of the effect of OA on coral reef calcifiers have described a wide variety of outcomes for studies using comparable partial pressure of CO 2 (pCO 2 ) ranges, suggesting that key questions remain unresolved. One unresolved hypothesis posits that heterogeneity in the response of reef calcifiers to high pCO 2 is a result of regional-scale variation in the responses to OA. To test this hypothesis, we incubated two coral taxa (Pocillopora damicornis and massive Porites) and two calcified algae (Porolithon onkodes and Halimeda macroloba) under 400, 700 and 1000 matm pCO 2 levels in experiments in Moorea (French Polynesia), Hawaii (USA) and Okinawa (Japan), where environmental conditions differ. Both corals and H. macroloba were insensitive to OA at all three locations, while the effects of OA on P. onkodes were locationspecific. In Moorea and Hawaii, calcification of P. onkodes was depressed by high pCO 2 , but for specimens in Okinawa, there was no effect of OA. Using a study of large geographical scale, we show that resistance to OA of some reef species is a constitutive character expressed across the Pacific.

“…Likewise, Albright et al (2008) and Jokiel et al (2008) observed no significant effect on planula settlement success in reduced aragonite saturation conditions. Given the limited experimental data of the effects of climate change on the survival of coral planulae and indications that planulae can attach to substrata even in highly acidified seawater (Edmondson, 1946), brooded planulae may therefore be resilient to the acidic oceans predicted for the future.…”

“…Many different methods have been used to estimate baseline coral reef metabolism. Most laboratory-based determinations of coral calcification rates as a function of aragonite saturation state (V AR ) are conducted for short periods (days to weeks; Leclercq et al 2000;Langdon and Atkinson 2005;Jokiel et al 2008) and are often characterized by an acute disturbance in V AR , which may result in an acute biological response (Langdon and Atkinson 2005). Laboratory studies provide valuable species-specific information, but can potentially miss synergistic abiotic forcings and ecological factors.…”

“…Laboratory studies provide valuable species-specific information, but can potentially miss synergistic abiotic forcings and ecological factors. Shore-based mesocosms (Jokiel et al 2008;Andersson et al 2009) and ''chamber''-type in situ mesocosms on reefs and benthic enclosures (e.g., the Submersible Habitat for Analyzing Reef Quality) using pumps to simulate water flow (Gattuso et al 1997;Yates and Halley 2006) provide quantitative estimates for reef metabolism on the time scale of hours, yet lack natural water circulation and movement of nutrients, carbon, and organisms.…”

Diel trends in carbon chemistry and hydrodynamic regimes were measured on a coral-dominated back-reef community in the Republic of Palau, western Pacific. Observed diel ranges over 5 d were pH 7.92-8.09, partial pressure of carbon dioxide 33.4-52.7 Pa, measured total alkalinity 2080-2272 mmol kg 21 , total dissolved inorganic carbon 1763-1939 mmol kg 21 , aragonite saturation state 2.84-3.98, and calcite saturation state 4.44-5.67. The combination of reef metabolism and hydrodynamic regimes drives this variability. We report net community calcification (NCC) and net community production (NCP) rates of 220.4 (6 7.8) to 41.2 (6 37.7) mmol CaCO 3 m 22 h 21 and 77.3 (6 95) to 64 (6 22) mmol C m 22 h 21 , respectively. Using a control volume approach, we show that NCC and NCP rate estimates are quite sensitive to the effective control volume dimensions. At this site, tracking vertical mixing of water masses within the control volume shows that active water mixing is often confined to a region 2-3 m above the corals. Vertical carbon mass fluxes into and out of the benthic environment were unexpectedly large for the slow current flow rates observed, suggesting that coral morphology or reef rugosity may affect mass transport of carbon and nutrients. The ranges of NCC and NCP values highlight the need for additional field work on various reefs to tune and optimize the control volume approach to achieve its full potential for reef metabolism monitoring.
