| Summary: | N2O is a greenhouse gas with a greenhouse potential 256 times higher than carbon dioxide on a century scale. The ocean is one of the important natural sources of this greenhouse gas. They affect the greenhouse gas budget of the atmosphere through the exchange of sea air interfaces, thereby affecting global warming. This data is the analysis data of N2O dissolved in seawater samples collected from CTD at different levels during China's 32nd Antarctic Scientific Expedition (2015-2016). It is of great significance for understanding the distribution and flux of N2O in the Antarctic Peninsula of the Southern Ocean, and has a guiding role in clarifying the impact of greenhouse gas exchange on climate change during the rapid retreat of sea ice in the Southern Ocean. 1. Measurement instrument name: Gas chromatography instrument model: Shimadzu 2010B Measurement method: Headspace calibration method: Use the national first-class N2O standard gas (with an accuracy of 1%) from the National Center for Reference Materials to calibrate the instrument signal value. 2. Observation method and data obtained. During the period from December 29, 2015 to January 14, 2016, seawater N2O samples were collected from 40 stations on the Antarctic Peninsula. 3. Observation area: The sea area under investigation during this voyage includes the Antarctic Peninsula
