Data from: Novel reverse radioisotope labelling experiment reveals carbon assimilation of marine calcifiers under ocean acidification conditions
<p><span>1. Ocean acidification by anthropogenic carbon dioxide emissions is projected to depress metabolic and physiological activity in marine calcifiers. To evaluate the sensitivity of marine organisms against ocean acidification, the assimilation of nutrients into carbonate shells and soft tissues must be examined.</span></p> <p><span>2. We designed a novel experimental protocol, reverse radioisotope labelling, to trace partitioning of nutrients within a single bivalve species under ocean acidification conditions. Injecting CO<sub>2</sub> gas, free from radiocarbon, can provide a large contrast between carbon dissolved in the water and the one assimilated from atmosphere. By culturing modern aquifer organisms in acidified seawater, we were able to determine differences in the relative contributions of the end members, dissolved inorganic carbon (DIC) in seawater and metabolic CO<sub>2</sub>, to shell carbonate and soft tissues. </span></p> <p><span>3. Under all pCO<sub>2</sub> conditions (463, 653, 872, 1137, and 1337 μatm), radiocarbon (Δ<sup>14</sup>C) values of the bivalve (<i>Scapharca broughtonii</i>) shell were significantly correlated with seawater DIC values; therefore, shell carbonate was derived principally from seawater DIC. The Δ<sup>14</sup>C results together with stable carbon isotope (δ<sup>13</sup>C) data suggest that in <i>S. broughtonii</i> shell δ<sup>13</sup>C may reflect the kinetics of isotopic equilibration as well as end-member contributions; thus, care must be taken when analyzing end-member contributions by a previous method using δ<sup>13</sup>C. The insensitivity of <i>S. broughtonii</i> to perturbations in pCO<sub>2</sub> up to at least 1337 µatm indicates that this species can withstand ocean acidification.</span></p> <p><span>4. Usage of radioisotope to dope for tracer experiments requires strict rules to conduct any operations. Yet, reverse radioisotope labeling proposing in this study has a large advantage and is a powerful tool to understanding physiology of aquifer organisms that can be applicable to various organisms and culture experiments, such as temperature, salinity, and acidification experiments, to improve understanding of the proportions of nutrients taken in by marine organisms under changing environments.</span></p>

Observed fluxes of POC, PIC and bSi at EqPac, HAUSGARTEN, OSP, PAP-SO and BATS/OFP from sediment traps and radioisotopes on depth profiles
<p>This dataset contains a compilation of observed fluxes of sinking particulate material (particulate organic carbon or POC, particulate inorganic carbon or PIC, and biogenic silica or bSi) at five ocean time-series sites obtained from sediment traps and radioisotopes. The five time-series sites were selected upon abundance of data on a monthly and depth basis. The sites are:</p> <ol> <li>Equatorial Pacific Process Studi (EqPac) in the upwelling region of the equatorial Pacific</li> <li>Long-Term Ecological Research observatory HAUSGARTEN, in the eastern Fram Strait, off Svalbard, at the Atlantic-Arctic boundary.</li> <li>Ocean Station Papa (OSP), in the southern portion of the Alaska Gyre in the NE subarctic Pacific</li> <li>Porcupine Abyssal Plain time-Series Observatory (PAP-SO), in the NE Atlantic off the SW of the UK</li> <li>Bermuda Atlantic Time-Series/Oceanic Flux Program joint site (BATS/OFP), in the northern Sargasso Sea, in the subtropical NW Atlantic </li> </ol> <p>The compilation contains a total of 7013 data points, where BATS/OFP accumulates 50% of all of them, followed by OSP (28%), HAUSGARTEN (10%), PAP-SO (10%) and EqPac (2%). The bulk of the collected data is in the euphotic zone and POC flux has a higher count than PIC and bSi. The origin of the 98% of the data is sediment traps, the remaining 2% (157 data points) are surface fluxes derived from radioisotopes.</p>
