Variability in sea ice carbonate chemistry: a case study comparing the importance of ikaite precipitation, bottom-ice algae, and currents across an invisible polynya by B. G. T. Else, A. Cranch, R. P. Sims, R. P. Sims, S. Jones, L. A. Dalman, L. A. Dalman, C. J. Mundy, R. A. Segal, R. A. Segal, R. K. Scharien, T. Guha

“…We used an invisible polynya as a natural laboratory to study the effects of inferred initial ice formation conditions, ice growth rate, and algal biomass on the distribution of carbonate species by collecting enough cores to perform a statistical comparison between sites located within, and just outside of, a polynya near Iqaluktuttiaq (Cambridge Bay, Nunavut, Canada). At both sites, the uppermost 10 cm ice horizon showed evidence of CO<span class="inline-formula">₂</span> off-gassing, while carbonate distributions in the middle and bottommost 10 cm horizons largely followed the salinity distribution. …”

High interannual surface <i>p</i>CO₂ variability in the southern Canadian Arctic Archipelago's Kitikmeot Sea by R. P. Sims, M. M. M. Ahmed, M. M. M. Ahmed, M. M. M. Ahmed, B. J. Butterworth, B. J. Butterworth, P. J. Duke, S. F. Gonski, S. F. Jones, K. A. Brown, K. A. Brown, C. J. Mundy, W. J. Williams, B. G. T. Else

“…By using a research vessel that is based in the remote Inuit community of Ikaluqtuutiak (Cambridge Bay, Nunavut), we have been able to reliably survey <span class="inline-formula"><i>p</i></span>CO<span class="inline-formula">₂</span> shortly after ice melt and access previously unsampled bays and inlets in the nearby region. …”
