Scoil Iosaef Naofa pupils on Mud Analysis field Trip
The 18th of April
was a warm sunny day and the class were going to do some mud analysis
to find out what the godwits are feeding on, and to calculate the amount
of godwit food is in the mudflats at Glounthaune, which is one of the
most important feeding areas for the godwits when they are in Cork harbour.
Becca Hayhow demonstrated how the mud was sampled using a core sampler.
Samples were collected from areas where the class saw godwits feeding.
The godwits were not too disturbed by the sample collecting, and remained
within 50 meters of Becca for most of the time. The class then returned
to the school in Cobh, and in the afternoon Becca and Jim Wilson showed
the pupils how to analyse the mud, sifting it carefully and searching
for any possible food items such as worms, snails and molluscs. Thanks
to Professor John O’Halloran of University College Cork, the pupils were
able to use two UCC microscopes to have a closer look at what they found
in the mud. Everyone had a great day, and with the data they collected
they intend to do some calculations to learn more about the Black-tailed
Godwits that visit Cork harbour.
