Seagrass meadow monitoring

How exciting was today. We headed out in the boat called Glaucus.  Our crew included scientists Paul and Dave, we had Peter and Micha on board as well.  Our science task was to sample the different living things found in the seagrass meadow. We used a very interesting sampling method to find out. It is called a BRUV (Baited Remote Underwater Video) techniques.

In this system we baited a small catch bag with pilchards. The bag was pegged down into the seagrass, we then put a brick with a GoPro remote camera on it facing the bag.  We left the BRUV units in the water for an hour and returned to get the units back. We completed 4 sites today. We put in 4 BRUV units at each site.

The sites were different from each other, as some were put in marine protectedareas and others in non protected areas.  This survey techniques is good because it captures the marine life without the effects of snorkelling and scaring the creatures away. We watched our footage back when we returned and we saw some amazing marine life. The bag attracted fish, crabs, stingrays, sea turtles, sea snails and marine worms.

We will use this type of sampling techniques when I return to school. It will be great to use it down at Pea Soup to try and find out what creatures are living in the seagrass.
