Maritime Museum Talk: Forecasting contamination

Watch recordings of our second NZ Maritime Museum breakfast talk on 19 August 2019. Ben Knight and Lincoln Mackenzie spoke about their research on forecasting and detecting marine contamination and harmful algal blooms.

New Zealand coasts are at the ‘end of the pipe’ for discharge from local rivers and streams, so seawater quality is sometimes compromised by bacteria from land-based activities. This can affect the revenue of shellfish growing areas and close local beaches to public use.

Near real-time forecasting of contamination

Ben Knight (Cawthron Institute) described a forecasting tool that provides a real-time ‘weather map’ prediction of bacteria in the sea.

Sensing algal blooms in the sea

Lincoln Mackenzie (Cawthron Institute) discussed two innovative simple, cost-effective and sensitive tests for early detection of harmful algal blooms (HABs). These tests can be used by public health agencies, the aquaculture industry and communities.
