Auditory Display: Axial Long Term Seafloor Inflation Record, short version

Based on cognitive load in informal learning environments, we knew we needed to reduce the length of our auditory displays. We started this process with the Long term Seafloor Inflation Record. We reduced the script and tightened up the auditory key, or legend, for the data sonification. The audio media player is below. For more about the version update and graph, please see our previous post on the Axial Seafloor Inflation Record auditory display.

Please note that the graph we sonified and created an auditory display for comes from the Axial Seamount blog from the Earth-Oceans Interactions Program site. The graph is a time-series plot of bottom pressure data of the long-term record of the seafloor from 1997 through 2021 in the Axial Caldera in the NE Pacific Ocean. The audio in the initial hook track is audio of the axial seamount eruption that University of Washington oceanographer John Delaney recorded. For more about the audio of the seamount eruption, check out the KUOW story.

Graphic that displays time-series plot of the long term record of seafloor from 1997 through 2021 in the Axial Caldera in the NE Pacific Ocean. The 1998, 2011, and 2015 volcanic eruptions are labelled in the graph and two horizontal, red dashed lines mark the 2011 and 2015 inflation threshold. In 2021, the 2011 inflation threshold was breached, but there hasn’t been an eruption yet.
