Impact Story

Where does Arctic mercury come from?
Summary
In research published in 2012, my colleagues and I used atmospheric observations from sites across the Arctic to test current understanding of Arctic mercury cycling. From this work, I proposed a new hypothesis: that Arctic rivers provide a very large pulse of mercury to the Arctic Ocean in late spring, which is ultimately responsible for a previously unexplained peak in Arctic atmospheric mercury in summer (<a href="https://ro.uow.edu.au/scipapers/4665/" target="_blank" rel="noopener">Fisher et al., 2012</a>). This work was highlighted in a News and Views piece in Nature Geoscience (<a href="https://www.nature.com/articles/ngeo1508" target="_blank" rel="noopener">Sönke and Heimburger, 2012</a>). My follow-up work then identified solar radiation and air temperature as the major meteorological factors driving Arctic mercury variability (<a href="https://ro.uow.edu.au/smhpapers/1375/" target="_blank" rel="noopener">Fisher et al., 2013</a>). This body of work kick-started a community effort to better understand the role of rivers in Arctic mercury cycling (e.g., <a href="https://pubs.acs.org/doi/10.1021/es400715r" target="_blank" rel="noopener">Emmerton et al., 2014</a>; <a href="https://www.sciencedirect.com/science/article/pii/S0048969715001199?via%3Dihub" target="_blank" rel="noopener">Søngergaard et al., 2015</a>; <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2015GB005124" target="_blank" rel="noopener">Zhang et al., 2015</a>). Most recently, my Arctic mercury hypothesis provided the <a href="https://theconversation.com/why-im-sailing-to-the-arctic-in-search-of-missing-mercury-37310" target="_blank" rel="noopener">motivation</a> for an independent research group to undertake five years of measurements in the Eurasian Arctic to observationally quantify (for the first time ever) the role of rivers in Arctic mercury cycling. Their work provided observational evidence that supports our original hypothesis and “confirms a new Arctic mercury cycling paradigm” (<a href="https://www.pnas.org/content/115/50/E11586" target="_blank" rel="noopener">Sonke et al., 2018</a>).

Detail of Impact
Mercury is a toxic pollutant. It is a particular problem in the Arctic, where elevated mercury levels have been measured in both marine wildlife and in indigenous populations that rely on marine-based diets. Understanding how mercury gets to the Arctic and into Arctic marine foodwebs is thus important for understanding and reducing mercury exposure. In 2012, <a href="https://ro.uow.edu.au/scipapers/4665/" target="_blank" rel="noopener">our paper in Nature Geoscience</a> proposed a new hypothesis for how mercury enters the Arctic Ocean, where it can subsequently be converted to its toxic form (methylmercury) and taken up by marine organisms. Previously, elevated mercury in the Arctic had been assumed to originate from emissions in the more populous mid-latitudes (North America, Europe, and Asia), where coal burning and other activities release large amounts of mercury to the air. The thinking was that these mid-latitude mercury emissions were transported to the Arctic in the atmosphere and from there deposited to the ocean. In our work, we showed that this assumption was inconsistent with observations of mercury in Arctic air. Instead, we found that the observations could be explained if Arctic rivers provided a very large pulse of mercury to the Arctic Ocean in late spring. This new hypothesis implied a fundamental re-thinking of mercury cycling in the Arctic, suggesting that on an annual timescale the Arctic Ocean was actually a source of mercury to the atmosphere, and not the other way around. Our paper had a significant impact on the Arctic mercury research community. One of the major limitations that we highlighted in the paper was a lack of data on mercury in Arctic rivers in spring and summer, which made it difficult to confirm or refute our hypothesis. This provided the motivation for a number of groups to make new mercury measurements in Arctic rivers (e.g., <a href="https://pubs.acs.org/doi/10.1021/es400715r" target="_blank" rel="noopener">Emmerton et al., 2014</a>; <a href="https://www.sciencedirect.com/science/article/pii/S0048969715001199?via%3Dihub" target="_blank" rel="noopener">Søngergaard et al., 2015</a>; <a href="https://www.pnas.org/content/115/50/E11586" target="_blank" rel="noopener">Sonke et al., 2018</a>). For example, in their paper Emmerton et al. noted "However, [Fisher et al., 2012] highlighted the lack of contemporary, seasonal sampling of Hg in large Arctic rivers... Between 2007 and 2010, we had the opportunity to address some of these issues affecting Hg concentration and export estimates, including the lack of sampling during ice-breakup." In a 2015 <a href="https://theconversation.com/why-im-sailing-to-the-arctic-in-search-of-missing-mercury-37310" target="_blank" rel="noopener">article in The Conversation</a>, Dr Lars-Eric Heimbürger linked to our paper as a key motivator for making new measurements in Russian rivers, by far the largest and least sampled rivers in the Arctic. "...<a href="http://www.nature.com/ngeo/journal/v5/n7/full/ngeo1508.html" target="_blank" rel="noopener">models suggest</a> that atmospheric emissions <a href="http://www.nature.com/ngeo/journal/v5/n7/full/ngeo1478.html" target="_blank" rel="noopener">can’t account</a> for all the mercury. A large source of mercury to the Arctic Ocean is missing. Rivers could provide such a source, especially during spring flood of Siberian rivers... That’s why we are now investigating the mercury discharge, especially during the spring flood, of one of the largest Siberian rivers, the Yenisei." Three years later, the results of that investigation were <a href="http://www.pnas.org/cgi/doi/10.1073/pnas.1811957115" target="_blank" rel="noopener">published in the Proceedings of the National Academy of Sciences</a>. Before this work, there were no measurements at all of mercury in Russian rivers during spring and summer. Now, mercury has been measured from spring to autumn for multiple years in two of the largest rivers in the Arctic (Yenisei and Severnaya Dvina). These comprehensive observations, originally motivated by our hypothesis, have also helped to confirm it: as they state in their paper, the authors "find that the spring flood mercury flux from Eurasian rivers is indeed large, which confirms a new Arctic mercury cycling paradigm."

Impact Story

Where does Arctic mercury come from?
Summary
In research published in 2012, my colleagues and I used atmospheric observations from sites across the Arctic to test current understanding of Arctic mercury cycling. From this work, I proposed a new hypothesis: that Arctic rivers provide a very large pulse of mercury to the Arctic Ocean in late spring, which is ultimately responsible for a previously unexplained peak in Arctic atmospheric mercury in summer (<a href="https://ro.uow.edu.au/scipapers/4665/" target="_blank" rel="noopener">Fisher et al., 2012</a>). This work was highlighted in a News and Views piece in Nature Geoscience (<a href="https://www.nature.com/articles/ngeo1508" target="_blank" rel="noopener">Sönke and Heimburger, 2012</a>). My follow-up work then identified solar radiation and air temperature as the major meteorological factors driving Arctic mercury variability (<a href="https://ro.uow.edu.au/smhpapers/1375/" target="_blank" rel="noopener">Fisher et al., 2013</a>). This body of work kick-started a community effort to better understand the role of rivers in Arctic mercury cycling (e.g., <a href="https://pubs.acs.org/doi/10.1021/es400715r" target="_blank" rel="noopener">Emmerton et al., 2014</a>; <a href="https://www.sciencedirect.com/science/article/pii/S0048969715001199?via%3Dihub" target="_blank" rel="noopener">Søngergaard et al., 2015</a>; <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2015GB005124" target="_blank" rel="noopener">Zhang et al., 2015</a>). Most recently, my Arctic mercury hypothesis provided the <a href="https://theconversation.com/why-im-sailing-to-the-arctic-in-search-of-missing-mercury-37310" target="_blank" rel="noopener">motivation</a> for an independent research group to undertake five years of measurements in the Eurasian Arctic to observationally quantify (for the first time ever) the role of rivers in Arctic mercury cycling. Their work provided observational evidence that supports our original hypothesis and “confirms a new Arctic mercury cycling paradigm” (<a href="https://www.pnas.org/content/115/50/E11586" target="_blank" rel="noopener">Sonke et al., 2018</a>).

Detail of Impact
Mercury is a toxic pollutant. It is a particular problem in the Arctic, where elevated mercury levels have been measured in both marine wildlife and in indigenous populations that rely on marine-based diets. Understanding how mercury gets to the Arctic and into Arctic marine foodwebs is thus important for understanding and reducing mercury exposure. In 2012, <a href="https://ro.uow.edu.au/scipapers/4665/" target="_blank" rel="noopener">our paper in Nature Geoscience</a> proposed a new hypothesis for how mercury enters the Arctic Ocean, where it can subsequently be converted to its toxic form (methylmercury) and taken up by marine organisms. Previously, elevated mercury in the Arctic had been assumed to originate from emissions in the more populous mid-latitudes (North America, Europe, and Asia), where coal burning and other activities release large amounts of mercury to the air. The thinking was that these mid-latitude mercury emissions were transported to the Arctic in the atmosphere and from there deposited to the ocean. In our work, we showed that this assumption was inconsistent with observations of mercury in Arctic air. Instead, we found that the observations could be explained if Arctic rivers provided a very large pulse of mercury to the Arctic Ocean in late spring. This new hypothesis implied a fundamental re-thinking of mercury cycling in the Arctic, suggesting that on an annual timescale the Arctic Ocean was actually a source of mercury to the atmosphere, and not the other way around. Our paper had a significant impact on the Arctic mercury research community. One of the major limitations that we highlighted in the paper was a lack of data on mercury in Arctic rivers in spring and summer, which made it difficult to confirm or refute our hypothesis. This provided the motivation for a number of groups to make new mercury measurements in Arctic rivers (e.g., <a href="https://pubs.acs.org/doi/10.1021/es400715r" target="_blank" rel="noopener">Emmerton et al., 2014</a>; <a href="https://www.sciencedirect.com/science/article/pii/S0048969715001199?via%3Dihub" target="_blank" rel="noopener">Søngergaard et al., 2015</a>; <a href="https://www.pnas.org/content/115/50/E11586" target="_blank" rel="noopener">Sonke et al., 2018</a>). For example, in their paper Emmerton et al. noted "However, [Fisher et al., 2012] highlighted the lack of contemporary, seasonal sampling of Hg in large Arctic rivers... Between 2007 and 2010, we had the opportunity to address some of these issues affecting Hg concentration and export estimates, including the lack of sampling during ice-breakup." In a 2015 <a href="https://theconversation.com/why-im-sailing-to-the-arctic-in-search-of-missing-mercury-37310" target="_blank" rel="noopener">article in The Conversation</a>, Dr Lars-Eric Heimbürger linked to our paper as a key motivator for making new measurements in Russian rivers, by far the largest and least sampled rivers in the Arctic. "...<a href="http://www.nature.com/ngeo/journal/v5/n7/full/ngeo1508.html" target="_blank" rel="noopener">models suggest</a> that atmospheric emissions <a href="http://www.nature.com/ngeo/journal/v5/n7/full/ngeo1478.html" target="_blank" rel="noopener">can’t account</a> for all the mercury. A large source of mercury to the Arctic Ocean is missing. Rivers could provide such a source, especially during spring flood of Siberian rivers... That’s why we are now investigating the mercury discharge, especially during the spring flood, of one of the largest Siberian rivers, the Yenisei." Three years later, the results of that investigation were <a href="http://www.pnas.org/cgi/doi/10.1073/pnas.1811957115" target="_blank" rel="noopener">published in the Proceedings of the National Academy of Sciences</a>. Before this work, there were no measurements at all of mercury in Russian rivers during spring and summer. Now, mercury has been measured from spring to autumn for multiple years in two of the largest rivers in the Arctic (Yenisei and Severnaya Dvina). These comprehensive observations, originally motivated by our hypothesis, have also helped to confirm it: as they state in their paper, the authors "find that the spring flood mercury flux from Eurasian rivers is indeed large, which confirms a new Arctic mercury cycling paradigm."
