Ocean Buffer Project

The ocean absorbs around a quarter of the world’s carbon dioxide. However, this comes at a cost. As CO₂ dissolves into seawater, it raises acidity levels. This puts heavy pressure on marine life, from plankton to coral reefs. Scientists call this ocean acidification, and it’s one of the biggest threats facing our seas today. Yet few people really understand it. That’s where this community-led carbon removal project in Cornwall comes in. The Ocean Buffer Project turns a hidden problem into something people can see, interact with and act on. Ash Morgan founded Ocean Buffer Project in Cornwall, driven by concern for ocean health and curiosity about marine science. Since then, the project has grown quickly, securing National Lottery funding in its very first year. Meanwhile, a newly appointed volunteer coordinator and safeguarding officer are helping the team prepare for its next stage.

Growing “Mini Oceans” on Land

Volunteers grow Nannochloropsis, a marine microalga, inside small, low-energy tanks made from recycled materials. As it grows, the algae absorbs carbon dioxide and converts it into biomass. The team then dries the biomass and locks it into materials such as biochar and clay composites. Eleven volunteers currently take part, choosing flexible roles that need no scientific background at all. Because everything runs off-grid, the project removes carbon without creating new emissions. It aims to capture around one tonne of CO₂ each year through this community-led approach to carbon removal in Cornwall.

Growing a Coastal Nursery

Funds from the John Good Group will help establish a new coastal biodiversity and native plant nursery at the Cornwall site. This support will help Ocean Buffer Project grow even further. The nursery will grow coastal and pollinator-friendly plants. These often struggle to survive erosion and heavy footfall along popular paths and beaches. Funds will cover seed trays, compost, tools and reclaimed planters. They will also support meadow seeding and pollinator planting to improve the site itself. Over time, the nursery will supply plants for local restoration projects. It also gives volunteers and schools a hands-on way to learn how coastal ecosystems work. In this way, the project will help protect Cornwall’s coastline for years to come.
