Snow and ice play their most important role in the nitrogen cycle as a barrier to land-atmosphere and ocean-atmosphere exchanges that would otherwise occur. The inventory of nitrogen compounds in the polar ice sheets is approximately 260 Tg N, dominated by nitrate in the much larger Antarctic ice sheet. Ice cores help to inform us about the natural variability of the nitrogen cycle at global an...

The purpose of a Safety Data Sheet (SDS), formerly known as Material Safety Data Sheets (MSDS), is to provide information on the hazards of working with a chemical and procedures that should be used to ensure safety. State and Federal law require that employers obtain an SDS for each hazardous substance they use or store and make the SDS available to employees. The PI/instructor is responsible ...

Global temperatures have increased by 0.8◦C since instrumental records began, and the last decade has been the warmest. This warming has been closely linked to increasing greenhouse gas concentrations due to human activities. Arctic warming is leading to thinning and disappearance of sea ice on the Arctic Ocean and the increased melting of the Greenland ice sheet. In the last decade the Antarct...
