Data and sea shanty whip up a storm

Scientists have transformed data captured during the most energetic series of extreme storms on record into a musical piece demonstrating the effects of climate change.

Song of the Sea, created by the University of Plymouth, UK, takes sea shanty What Shall We Do With the Drunken Sailor?, and manipulates it using actual data captured by the Southwest Regional Coastal Monitoring Programme. The result is a piece that listeners will initially recognise, but which then changes as the data reflect the stronger winds and higher waves generated as the storm reached its destructive peak.

The project comes from a collaboration between the University of Plymouth’s Marine Institute and its Interdisciplinary Centre for Computer Music Research (ICCMR). It is centred on data gathered over a 48-hour period in February 2014, which resulted in the main rail line being washed away at Dawlish in south Devon.

Those two days were part of a series of storms that wreaked havoc along the Atlantic coasts of western Europe, with research by the University subsequently demonstrating them to have been the most energetic storms to hit western Europe.

To create Song of the Sea, researchers assigned elements of the data to segments of the music and as the data changes the song changes with it. For example, wave height data were aligned to an echo effect on the words, distorting them as they grew more powerful. Wind speed was assigned to tempo, speeding up the piece as it intensified.

Pressure was aligned with pitch, so that as the pressure dropped in the middle of the storm, the vocals deepen and grow more slurred and ominous. And temperature was assigned to a distortion effect on the drum, causing it to ‘crunch’ as the weather grew colder.

Professor Richard Thompson, director of the Marine Institute, said: “This project highlights our connection to nature and the very serious issues occurring as a result of climate change.

"It provides a snapshot of the devastation and destruction extreme storms can cause, but also shows how our relationship with the planet has become more distorted."

Researchers working in the ICCMR have for many years endeavoured to use ground-breaking musical compositions as a means of breaking down complex science.

"There is no barrier to representing the far-reaching effects of climate change.”

Professor Eduardo Miranda, head of the ICCMR, added: “Historically, scientific data has normally been conveyed visually, as charts or illustrations. However, the combination of sound and images provides significantly more alternatives to convey information.

"Song of the Sea is a novel way of using actual climate data in such a way that it controls the music. And with extreme natural events predicted to increase in frequency and ferocity, there is no barrier to its principles being applied to represent the far-reaching effects of climate change on our planet.”
