<p style="margin:0in;margin-bottom:.0001pt">Surface water samples collected in the western South Pacific Ocean in the austral fall of 2015, 2016, 2017, and 2018, were used to characterize the variability of carbonate parameters in the region and to identify
mechanisms that may have impacted these parameters over interannual timescales. The South Pacific Subtropical Gyre stayed fairly constant with regard to its carbonate parameters over 2015-2018. The Chatham Rise and Subtropical Front regions to the east of
New Zealand experienced slight increases in temperature and pH over the entire period. Between 2015 and 2016, and between 2017 and 2018, there were significant decreases in total alkalinity. Calcite and aragonite saturation state were also evaluated and were
found to increase over the four-year study period. Based on sensitivity test study results, changes in pH and total alkalinity impacted calcite and aragonite state most significantly. Therefore, we hypothesize that there was a large amount of NO<sub>3</sub><sup>—</sup>supported
photosynthesis by calcifying phytoplankton, specifically, the coccolith, <i>E. Huxleyi,
</i>a species prolific in this region.</p>
