Auditory Display: Carbon Net Flux Between Ocean and Atmosphere, v2

Based on input from our team, research with blind and low-vision (BLV) students in schools, and insights learned over the past year, we have updated our auditory display for the Carbon Net Flux Between Ocean and Atmosphere data nugget. I re-recorded narration audio, and mixed underlying music, sound effects, and data sonification snippets as part of the auditory display. We also added an initial hook track and an introduction. The audio media player is below. A graph of the data is also displayed below.

Headphones are best for listening. Feel free to reach out and let us know what you think.

Graphic that contains two data sets of Coastal carbon dioxide flux between ocean and atmosphere. These data sets show the seasonal cycles of CO2 air-sea gas exchange during 2017 at two coastal locations – the Endurance Array in the NE Pacific (shown as black dots), and the Pioneer Array in the NW Atlantic (shown as white dots). Most of the outgassing — or CO2 release from the ocean into the atmosphere, occur during the summer months. CO2 absorption — a net flux of CO2 from the atmosphere into the ocean occurs throughout the year.
