Dunedin’s secondary school citizen scientists have collected the data from Tomahawk Lagoon and are preparing to present their findings to the local community.

The group met at the Ocean Grove Hall on Tuesday to do some final data analysis in preparation for their presentations on November 3.

Pupils from John McGlashan College, Otago Girls’ High School, Bayfield High School, Tahuna Normal Intermediate and King’s High School spent the morning investigating the bugs found in their water samples.

John McGlashan pupil Lourenco Botafogo (16) collected and separated the different species found in the samples.

Ecotago scientist Andrew Innes said the group did a bug count about six weeks ago.

Next month’s reporting day was an opportunity for the pupils to talk about what they had been doing and had learned.

“We’re trying to focus on the kids and what they have been learning.”

University of Otago freshwater scientist Dr Marc Schallenberg would share his knowledge and passion for good water quality in New Zealand in places such as Tomahawk Lagoon, Mr Innes said.

The pupils had met fortnightly to monitor the biodiversity and chemical and physical patterns of Tomahawk Lagoon and its catchments.
