Auditory Display: Axial Long Term Seafloor Inflation Record, 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 2015 Axial Seamount Eruption Data Nugget. We updated data sonifications, 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. Please note that the Ocean Labs data nugget does not include the graph (included below) that we sonified and developed into an audio display; yet, the graph is important to demonstrate a core lesson that seafloor inflates and deflates over time as a result of volcanic activity. 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.

Headphones are best for listening.

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.
