Current research and/or projects
The main scope of my work is identifying to species, sex and staging zooplankton collected through the LaPerouse Monitoring Program; Station Papa and Line P Times Series; and the High Seas Salmon surveys. Plankton is the base of the oceanic food web and how the zooplankton is doing determines how well animals like salmon; sea birds and whales will be faring in the near future. El Niño events change the plankton community structure which causes havoc up the food web. Constant monitoring of what species are in the area and where gives scientists a heads up of potential problems.
