The Big Seaweed Search first launched in 2009 under the auspices of the Marine Conservation Society and the Natural History Museum in the UK. Hundreds of people have taken part and the data gathered, alongside other research, show that the distribution of seaweeds around the UK is changing. The survey supports research on ‘three key environmental issues: rising sea temperature, the arrival and spread of non-native species of seaweeds, ocean acidification (the sea becoming more acidic because of absorbing carbon dioxide from the air.’ The website provides information about how to become involved in this citizen science project.

The mission of this initiative is to restore oyster reefs to New York Harbor through public education. More specifically, Billion Oyster Project aims to replant 1 billion oysters in the harbour by 2035, with the participation of a million New Yorkers. And they are well on their way. So far they have planted 28 million oysters, with the participation of 6,000-plus local students and 9,000-plus volunteers. Their grant will support a citywide symposium for local students to present their research on ecosystems, marine life and water quality in New York Harbor, and on opportunities to make restoration more effective and engage their communities more deeply.
