Antarctic Free Ocean Carbon Dioxide Enrichment Experiment

Parent node for data sets for the Antarctic Free Ocean Carbon Dioxide Enrichment experiment (antFOCE), AAS project 4127.

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.

本节点为南极自由海洋二氧化碳富集实验（Antarctic Free Ocean Carbon Dioxide Enrichment experiment，简称antFOCE）、AAS项目4127号的数据集父节点。

项目概述：
当前人类排放的二氧化碳中，有四分之一被海洋吸收。海水吸收二氧化碳后会改变自身化学性质——降低海洋pH值（即提升海水酸度），这会对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重隐患。由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海洋酸化带来的最沉重负担。本研究将开展全球首个极地原位二氧化碳富集实验，以探明在二氧化碳排放量持续增长的背景下，海洋酸化对南大洋海底群落的潜在影响。
