Climate Change in Temperate Seas

Our research forecasts future habitats

We use projected estimates of climate change (e.g. ocean acidification, temperature) as modified by local management (e.g. fishing & pollution).  This work is being done within the context that global climate continues to change.  A key concern centres on the rate of current change.  Even if we maintain CO2 emissions at current levels, an unlikely scenario, CO2 concentrations in the atmosphere will increase by over 50 % in coming years. This increase will inturn cause ocean acidification as more CO2 is dissolved into the worlds oceans.

Our forthcoming work will use a combination of laboratory and field techniques.  Lab studies can be carefully controlled, but the range of ecological interactions is quite limited. Conversely, field studies benefit from interactions within a natural community, but spatial and temporal variation in climate parameters do not behave exactly the same as future ocean conditions. Combining both approaches will provide a whole that is greater than the sum of its parts.
