What to do

Marine Metre Squared is a fun and easy way to get involved in scientific monitoring of your local coastal environment.

  1. Select an area of your local coastline to monitor and explore.
  2. Download a data sheet and seashore guide suitable for your selected area.
  3. Record as much as your can find in your 1 m x 1 m square patch.
  4. Log your findings at Mm² and join the online discussions with other Mm² members.

Go back for more

To build up a picture of how the marine environment changes over time, try to complete this action at least once more in the same area – either a few metres away, or even during a different season.

Then go back and record your findings online, helping Mm² to build up their database on New Zealand’s amazing marine environments.
