The damage being caused to our ocean by human activity and climate change has never been more apparent. However, the precise effects of ocean acidification – and how it might impact the marine environment now and in the future – are sometimes difficult to convey.
A new collaboration between world-leading researchers from the University of Plymouth, and Plymouth-based artist and scientist Dr Kate Crawfurd, aims to overcome that in a striking but playful and innovative way.
The Ocean Organ illustrates, using installation and theatre, the many ways in which the climate emergency is affecting the ocean’s ability to act as sources and sinks for carbon dioxide.
Designed to resemble a cathedral organ, it consists of a series of pipes bubbling with a spectrum of coloured liquids based on the chemical effects of CO₂ on the ocean.
The colour of seawater within the pipes can be altered depending on the differing levels of CO₂ present, using red cabbage as a natural pH indicator dye that reacts quickly to small pH changes.
The installation is accompanied by examples of seashells and other calcified marine life to demonstrate the effects of ocean acidification on species vital to the health of the entire planet.
It also examines some of the solutions that could reduce rising carbon dioxide levels such as floating wind farms, seaweed farming and the recovery of coastal wetlands.
The project is partly inspired by the research of Jason Hall-Spencer, Professor of Marine Biology at the University of Plymouth, and one of the world’s leading experts on ocean acidification and warming.
He led the first study to show the ecosystem effects of long-term ocean acidification and, with colleagues across the world, has demonstrated that it could have serious consequences for marine life and for the millions of people globally whose lives depend on coastal protection, fisheries and aquaculture.
Dr Crawfurd worked on theatrical sets for the Sydney Opera House, the National Theatre and in the West End before studying Marine Biology at the University, graduating in 2001.
She subsequently completed a PhD on the effects of rising CO₂ and phytoplankton and now combines her passion for art and the ocean through a number of eye-catching projects. She added:
“What we are trying to do through the Ocean Organ is to communicate science in quite a playful and positive way. There is no doubt the message can be quite heavy, in terms of the effect our actions are having on the environment. But in order to inspire change, we need to engage people of all ages and make them not only appreciate the scale of the problem but that they can also be part of the solution.”

It is hoped to showcase the Ocean Organ publicly later this year at a variety of events in Plymouth and further afield, subject to COVID-19 restrictions.
The collaboration was facilitated as part of the Creative Associates initiative, overseen by the University’s Sustainable Earth Institute and supported by Higher Education Innovation Funding (HEIF). The initiative is designed to uncover novel and innovative ways of communicating research to a public audience.
We are ranked the number one university globally for the United Nations’ Sustainable Development Goal number 14: life below water.
The award recognises the quality of our marine research and teaching as well as our efforts to reduce the impact of campus activities on the marine environment. The Times Higher Education Impact Rankings are the only global performance tables that assess universities against the United Nations’ Sustainable Development Goals (SDGs).
