Citizen Scientists wanted!

Kia Ora and welcome to the Marine Metre Squared website!

Marine Metre Squared is an easy way for anyone to survey the plants and animals living on their local seashore.

The NZ Marine Studies Centre, University of Otago, is encouraging everyone to participate in long term monitoring of their marine environment – the Marine Metre Squared. Anyone can take part – individuals, families, schools and community groups.

Here you can find everything you need to get involved in this exciting nationwide Citizen Science project, start surveying your local seashore, and find out where plants and animals that live between the tides are found around New Zealand.

Take a moment to join the Marine Metre Squared project – it's easy and free.

As a registered member you can get full access to our online Mm2 database where you can add your own survey data to show others what’s living between the tides on your local shore, and compare your shore with others in New Zealand to find out which species live where using our simple mapping and analysis tools. 

Registered members can also join our online community where you can connect with other members of the Mm2 network, get help with species identification, take part in new projects and challenges and suggest mini-projects of your own.
