The 140-person crew\u00a0will spend\u00a065 days sailing through the western Arctic Ocean conducting 48\u00a0separate research projects, according to the NSF.<\/p>\n<p>\u201cThe Arctic has been an understudied system because it is an extremely harsh\u00a0environment that is hard to get to,\u201d Kadko says. \u201cIt\u2019s very exciting and gratifying that three separate nations can come together and cooperate for this project. In the end,\u00a0there will be a huge archive of data that scientists will be using for decades to come.\u201d<\/p>\n<p>From their designated region, Kadko and his team will be taking samples from the ocean surface to the sea floor,\u00a0the atmosphere, ice, snow and sediments; they will then measure the amounts of various trace\u00a0elements and isotopes \u2013 which include micronutrients such as iron, zinc and cobalt that are essential\u00a0for life, and toxic contaminants such as arsenic an\u00a0copper.<\/p>\n<p>Robert Anderson \u2013 a research professor in the Lamont-Doherty\u00a0Earth Observatory at Columbia University and former co-chair of GEOTRACES, the\u00a0international program that\u00a0tracks trace metals through the world\u2019s oceans\u00a0\u2013\u00a0says the\u00a0processes that impact the distribution of these nutrients in the Arctic Ocean could\u00a0impact the ocean\u2019s ecosystem in significant ways.<\/p>\n<p>\u201cWe want to understand how the Arctic ecosystem and the base of the food web \u2013the phytoplankton that feed all of the higher organisms in the Arctic Ocean \u2013 get the\u00a0nutrients that they need,\u201d Anderson said.<\/p>\n<p>By analyzing and interpreting the samples they collect, Kadko hopes to gain an\u00a0understanding of the current biogeochemical distributions \u2013 or \u201cfingerprints\u201d \u2013 of the Arctic\u00a0Ocean, resulting in an understanding of its chemical nature.<\/p>\n<p>\u201cThe distributions of chemicals in the Arctic are there because of processes that put\u00a0them there,\u201d Kadko says. \u201cBy interpreting these fingerprints, we get to know more\u00a0about how the Arctic operates today.\u201d<\/p>\n<p>The team will help\u00a0establish baseline levels of trace elements, isotopes and\u00a0contaminants found in the Arctic today to compare against future conditions.<\/p>\n<p>Climate\u00a0change continues to\u00a0impact the region\u00a0and\u00a0a number of countries are developing\u00a0plans to expand shipping, oil drilling, fishing and other forms of industrial\u00a0development in the Arctic. The expedition\u2019s findings will ultimately help scientists and policy makers get a clearer picture\u00a0of how different factors could affect the future\u00a0geochemistry of the ocean,\u00a0specifically with the increase of greenhouse gases.<\/p>\n<p>\u201cCertainly in 20 years, the geochemistry of the arctic will be different,\u201d Kadko says.\u00a0\u201cThere will be less ice and probably be more economic development in the Arctic, so\u00a0we want to know how much of an impact those changes will have on the Arctic\u00a0compared to what we have today.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"excerpt pull-left\">Oceanographer David Kadko has\u00a0been to the Arctic Ocean several times over the course of his\u00a0career, but on Aug. 9\u00a0he left\u00a0for one of the\u00a0biggest undertakings and international collaborations in the history of Arctic\u00a0research.
