<div><p>From Archer et al. (2018): The mesocosm experiment was conducted in Gando Bay, on the east coast of Gran Canaria (27° 55' 41" N, 15° 21' 55" W) in the subtropical North Atlantic. Sample processing, analysis and further experiments were conducted in the laboratories of Plataforma Oceánica de Canarias (PLOCAN), Gran Canaria. The full experiment took place from 23rd September to 25th November 2014. The design and deployment of the Kiel Off-Shore Mesocosms for future Ocean Simulations (KOSMOS) facility has previously been described in detail (Riebesell et al., 2013).</p>
<p>Sampling and analytical procedures: The experimental set-up and sampling of the mesocosms is described in Taucher et al. (2017).</p>
<p>Procedures for the analysis of reduced sulfur compounds was based on purge-and-cryotrap approaches linked to a gas chromatograph with either flame FPD or mass spectrometric detector and is described in Archer et al. (2018).</p>
<p>Quantification of dissolved DMSO [DMSOd] closely followed the protocol of del Valle et al. (2007) and is reported in Archer et al. (2018).</p>
<p>Additional data from the experiment has been deposited on the PANGEA database: <a href="https://www.pangaea.de/?q=KOSMOS_2014" target="_blank">https://www.pangaea.de/?q=KOSMOS_2014</a></p></div>
KOSMOS14 DMSPO Concentrations
<div><p>As described in Archer et al. (2018), [H+] was calculated from pH on the total scale (pHT) calculated from TA and DIC in CO2SYS (Pierrot et al., 2006) using the carbonate dissociation constants K1 and K2 of Lueker et al. (2000). On each sampling day, total alkalinity (TA) was measured using a potentiometric titration approach and dissolved inorganic carbon (DIC) by infrared absorption as described in Taucher et al., (2017).</p>
<p>Problem Report:<br />
Note, a leak was detected in mesocsom M6 on Experimental Day 27. No further sampling was undertaken from that mesocosm.<br />
Note, DMSOd was quantified over only the first phase of the experiment T-3 to T25.</p>
<p>BCO-DMO Processing:<br />
- deleted empty columns;<br />
- modified parameter names (removed brackets (special characters); replaced spaces w/ underscores; renamed [H+] to "proton_conc");<br />
- filled in blanks with "nd" (no data);<br />
- reformatted date to yyyymmdd (was mm/dd/yy).</p></div>
