antFOCE Carbonate chemistry data sets

Carbonate chemistry data sets for the Antarctic Free Ocean Carbon Dioxide Enrichment experiment, Casey Station, East Antarctica, 2014/15.Project Summary:Currently, a quarter of the CO2 we emit is absorbed by the ocean. CO2 absorption in seawater changes its chemistry – reducing ocean pH (raising its acidity) – which has significant impacts on biological processes and serious implications for the resilience of marine ecosystems. As CO2 is more soluble in cold water we expect polar ecosystems to bear the heaviest burden of this 'ocean acidification'. We will perform the first in situ polar CO2 enrichment experiment to determine the likely impacts of ocean acidification on Southern Ocean sea-floor communities under increasing CO2 emissions.

东南极凯西站2014/15年度南极自由海洋二氧化碳富集实验碳酸盐化学数据集。项目概述：当前人类排放的二氧化碳中约有四分之一被海洋吸收。海水中的二氧化碳吸收过程会改变海水化学特性——降低海洋pH值（提升水体酸度），这将对海洋生物过程产生显著影响，并对海洋生态系统的恢复力造成严峻挑战。鉴于二氧化碳在冷水中溶解度更高，我们预计极地生态系统将承受这场“海洋酸化”带来的最沉重负担。本研究将开展首个极地原位（in situ）二氧化碳富集实验，以明确在二氧化碳排放持续增加的背景下，海洋酸化对南大洋海底群落可能造成的影响。
