Summary: Collected soil cores across the EC footprint

Camilo, Robert and I arrived at Maybery at around 9 am. It was a sunny day with light wind. The visit was to collect 5 soil cores across the EC tower footprint. The wetland was dry, water was only present in the channels.

We used 4 inch PVC tubes and a stainless steel core shoe with a core catcher.

We took soil cores at 20, 60 and 100 m away from the EC tower towards the northwest. These sites consisted of cattail, phragmites and edge-of-channel "land-cover type", respectively. To reach these sites, we followed the edge of the chanel in front of the tower to the left and then walked through the wetland. We found 3 wide areas where the cattails and also phragmites were horizontally tilted as if an helicopter had landed on top of them (otters?).

We took the car and drove to the other side of MB wetland to reach the last two coring sites, located at 170 and 270 m away from the tower. These sites consisted of cattail "cover type". Crossing through the wetland we saw more areas where cattails were tilted.

All of the cores were > 75 cm long, except for that sampled at the edge of the channel which was 36 cm long.

Soil samples were measured for dry bulk density, soil organic carbon, total nitrogen, organic matter content, δ13C, and total 210Pb.

We left at around 5.30 pm.
