Biography

My research focuses on using zooplankton size distributions to understand the implications of climate change on fisheries productivity. I’m particularly interested in long term zooplankton time series and how we can use them to validate and compare different modeling and experimental approaches to quantifying zooplankton production.

Zooplankton play a key role in the World’s oceans, acting as the fundamental link between phytoplankton and commercially valuable fisheries. These highly diverse ubiquitous organisms provide an important source of nutrition for a myriad of marine organisms. Past estimates of secondary production (zooplankton production) have proven to be labor intensive and overall inadequate in the past. My research focuses on estimating secondary production using zooplankton size distribution. Since marine pelagic food webs are largely size structured, and important rates (i.e., growth, mortality) scale with size, we can actually use size distribution to predict secondary production. I am currently working on combining zooplankton net-samples and laser optical particle counter (LOPC) with multi-frequency acoustics data collected by DFO on the Line P and LaPerouse voyages to estimate secondary production.
