Oceanography adventures for Year 10 geographers

"Year 10 Geography Elective students had a fantastic day at Balmoral and Chowder Bay doing field work for their Oceanography topic," said Head of Sustainability Carmelo Fedele.

The program, run by Land’s Edge, is a comparative study investigating the abundance and diversity of sea urchins and the presence of kelp forests within Sydney Harbour.

Students participated in a snorkel survey at the two locations collecting data on the abundance and diversity of kelp and sea urchins. Prior to the survey, students did an introductory snorkel session allowing them to become comfortable and familiar with the equipment and study area.

See what some of the students had to say below:

“I had so much fun and I learnt a lot. I learnt that there is a direct correlation between the sea urchins and kelp numbers. I really appreciated being able to go outside of the class and see what we’ve been learning in the real world,” said Oliver.

“I learnt kelp is not a plant, it’s an algae. It was interesting that the kelp concealed the depth of the sea floor,” said Chris.

“I preferred Balmoral to Chowder Bay because it had clearer water and more biodiversity. I learnt that sea urchin eat kelp and that affects broader biodiversity,” said Will.
