Show more What does the tide mean, and could it be trying to tell us something? Multimedia artist Signe Lidén reflects on both ancient and emerging knowledge across disciplines and cultures that understands the tide as more than just a mechanical phenomenon. While recording sounds on the dunes of an island off Denmark, Lidén was surprised by the rapid rise in sea level without being able to see the change from moment to moment. She has since devoted herself to studying the tide, recording an entire tidal zone using a 28-metre canvas as a microphone, and noticing the different sense of time she gets through close and extended listening. Could a deeper connection to the tide offer new ways of sensing and relating to the world around us, and help us to grasp the scale of environmental change that is happening in it?
