Seaweek - Ecotago Water Quality Monitoring Training Day

Sorry this event has been and gone


  • Thu 23 Feb ’17, 9:00am – 12:30pm


Ocean Grove Domain Hall, Tomahawk Road, Otago


All Ages

Ticket Information:

  • Free Admission

EcoTago will facilitate a community-based water quality investigation into the environmental health of Tomahawk Lagoon (TL). Currently, the community will be based around teams from Tahuna Normal Intermediate school, Bayfield High School, John McGlashan College and Otago Girl’s High school working closely with Ecotago/Ocemes advisory and expert group.

These teams will regularly monitor the water at selected sites in Tomahawk and the stream discharging into the upper lagoon. The data gathered will include these variables: water temperature, dissolved oxygen, pH, electrical conductivity, salinity, clarity/turbidity, dissolved nitrogen and phosphorus and E Coli bacteria as well as more general habitat observations such as the depth of the water and animals and plants observed.

These data will be entered onto our website to be accessible to all teams and the wider Tomahawk community. These data will undergo collation and critical analysis with an environmental “report card” being presented to the wider community at the end of the year.

To steer this monitoring programme in the right scientific direction we will be having a “training half day” at the Tomahawk Lagoon community hall on Feb 23rd to show the teams how to do the monitoring; gathering water samples correctly, using instruments that will measure the different variables in situ, highlighting relevant general site observations and understanding what samples will need further analysis in a laboratory. All teams will have the opportunity to participate in the laboratory techniques. All teams will be presented with handbooks to support the different methods being used.

Regular monitoring will be carried out usually on a Wednesday 12:00pm-1:30pm, these details are being discussed.

The “training half day” will be supported by our scientific experts who be leading the different parts of the learning programme. These experts are: Dr Marc Schallenberg, Dr Jonathan Kim, Andrew Innes and Mary Thompson (Regional Representative Bird NZ)

An important aspect of the half day is to emphasise the commitment needed to learn how to do the regular monitoring well and contribute effectively to this important project. Later in the year, we will be showcasing the programme to the wider Tomahawk Lagoon community to show them what we are doing and encourage them to help with the monitoring.

It is expected that the teams will contribute to the “teaching” and sharing on that day. The programme is included below.

9:00am - Meet at the Ocean Grove Domain Hall.
Introduction to the monitoring programme. What does it mean to investigate the environmental health of TL (Dr Marc Schallenberg and Councillor Gretchen Robertson and Andrew Innes). What did we find out in 2016?

9:45am - 12:00nn - How do we do the monitoring? Hands on time. Monitoring programme.
Monitoring handbook
Partial monitoring (what variables?), field observations and instrument readings, once every two weeks.

Full monitoring (what variables?) is partial monitoring as well as water sample collection and analysis, once a month.

12:00pm -12:30pm - Reporting back... what have we found out? Dates and times. Plans for our first sampling and monitoring day.

Note: We will be working outside on the edge of the Tomahawk Lagoon, so sensible dress and footwear (waders excellent) is important. Be prepared to stay warm and dry when you are working. Schools please check your EOTC safety procedures!! Bring some snacks!

Booking essential. To book contact, Andrew Innes (Project facilitator)
