The central element of the project is a month-long research expedition to the Yukon River Delta in Alaska. The expedition provides a deep intellectual and cultural immersion in the context of an authentic research experience that is paramount for "hooking" students and keeping them moving along the pipeline to careers as Arctic scientists. The overarching scientific issue that drives the research is the vulnerability and fate of ancient carbon stored in Arctic permafrost (permanently frozen ground). Widespread permafrost thaw is expected to occur this century, but large uncertainties remain in estimating the timing, magnitude, and form of carbon that will be released when thawed. Project participants are working in collaborative research groups to make fundamental scientific discoveries related to the vulnerability of permafrost carbon in the Yukon River Delta and the potential implications of permafrost thaw in this region for the global climate system. This data set includes permafrost cores, with ammonium, nitrate, volumetric ice content, N mineralization rates, %C, and %N results from the 2017 expedition. arctic sediment carbon nitrogen fire alaska None Creative Commons Attribution 4.0 International https://spdx.org/licenses/CC-BY-4.0.html CC-BY-4.0 These data are from the Yukon-Kuskokwim River Delta, Alaska, approximately halfway between Bethel and St. Mary's. The region recently burned in 2015 and has older burns from 1972. The area is flat with numerous lakes and wetlands. Terrestrial landscapes are peat plateaus roughly 1-3 meters above wetlands, stream, and lakes. All of these samples are from lake sediment cores. -163.3736 -162.3953 61.3053 61.1861 2017-06-25 2017-08-06 http://purl.org/dc/elements/1.1/subject http://purl.obolibrary.org/obo/ENVO_01000177 A synopsis of the dataset describes its purpose and contents, including one or more paragraphs as well as table(s) and figure(s) that summarize the data included in the data paper, including a summary of key findings if appropriate. An introduction goes here. It can include multiple paragraphs. And these paragraphs should have enough text to wrap in a wide browser. So, repeat that last thought. And these paragraphs should have enough text to wrap in a wide browser. So, repeat that last thought. Text can also cite other works, such as [@jones_2001], in which case the associated key must be present as either the citation identifier in a bibtex element in the EML document, or as the id attribute on one of the citation elements in the EML document. These identifiers must be unique across the document. Tools such as Pandoc will readily convert these citations and citation entries into various formats, including HTML, PDF, and others. And bulleted lists are also supported: - Science - Engineering - Math It can also include equations: $$\left( x + a \right)^{n} = \sum_{k = 0}^{n}{\left( \frac{n}{k} \right)x^{k}a^{n - k}}$$ Plus, it can include all of the other features of [Github Flavored Markdown (GFM)](https://github.github.com/gfm/). Some intro text in the getting started, then break into subsections. Note that the first line of markdown text defines the starting column for all subsequent indenting. ## Level 2 heading We use a level 2 heading because Level 1 would be at the same level as the main sections of the paper. ## Another level 2 heading With some information.
