@article{Anderson_Macdonald_2015, title={Observing the Arctic Ocean carbon cycle in a changing environment}, volume={34}, url={https://polarresearch.net/index.php/polar/article/view/3251}, DOI={10.3402/polar.v34.26891}, abstractNote={<p>Climate warming is especially pronounced in the Arctic, which has led to decreased sea-ice coverage and substantial permafrost thawing. These changes have a profound impact on the carbon cycle that directly affects the air–sea exchange of carbon dioxide (CO<sub>2</sub>), possibly leading to substantial feedback on atmospheric CO<sub>2</sub> concentration. Several recent studies have indicated such feedback but the future quantitative impact is very uncertain. To minimize these uncertainties, there is a need for extensive field studies in order to achieve both a better process understanding as well as to detect probable trends in these processes. In this contribution, we describe a number of processes that have been reported to be impacted by climate change and suggest a coordinated international observational programme for their study.</p><p><strong>Keywords:  </strong>Ocean time series; international coordination; climate change.</p><p>(Published: 10 December 2015)</p><p><strong>Citation:</strong> <em>Polar Research</em> 2015, <em>34</em>, 26891,http://dx.doi.org/10.3402/polar.v34.26891</p&gt;}, journal={Polar Research}, author={Anderson Leif G. and Macdonald Robie W.}, year={2015}, month={Dec.} }
