Hi! My name is Louise Cameron (She/Her) and I’m a marine ecologist and carbonate chemist. My research focusses on the impacts of ocean acidification and warming on marine bivalves and their fisheries. I answer these questions using a combination of field studies of bivalve performance across naturally occurring pH gradients that can be used as a proxy for future climate change, and through tank experiments where I expose bivalves to experimental climate change treatments. I measure fisheries relevant performance metrics in these studies such as growth, meat condition and shell strength. I am also interested in calcification physiology and I am investigating how the chemistry of the bivalve calcifying fluid, the extrapallial fluid, changes under ocean acidification.
I recently started a postdoc with Dr. Aleck Wang at WHOI, where I will be measuring benthic carbonate chemistry across Atlantic sea scallop fishing grounds and using this data, alongside the sea scallop physiology data I collected during my PhD, to create a spatially explicit model of the sensitivity of Atlantic sea scallop fishing grounds to future ocean acidification.
My pronouns are She/Her. I’m originally from Scotland, and in my spare time I’m a musician, quilter, and baker. My research interests include:
The bulk of my research investigates how ocean acidification and climate warming affects marine organisms’ physiology and fitness. Ocean acidification is the process by which increasing carbon dioxide is dissolving in our ocean’s surface, thus lowering its pH and calcium carbonate saturation state. I am particularly interested in how marine calcifiers (shell builders) respond to changing environmental conditions. My research is multi-disciplinary, covering aspects of mineralogy, biomechanics, physiology and biogeochemistry.
I am interested in how the processes marine organisms use to build their shells change in response to ocean acidification and climate warming. The ways different species respond to climate change are variable and I am interested in what phyiological processes underlie this variability. Some calcifiers, such as tropical corals, have been shown to increase the pH at their site of calcification by pumping hydrogen ions out of their calcifying fluid in exchange for calcium. By increasing pH, they increase their calcium carbonate saturation state, which promotes calcification. I am interested in the functioning of this mechanism under ocean acidification and climate change scenarios. Bivalves have a similar calcifying fluid, the extrapallial fluid, and I am also interested in whether bivalves use a similar mechanism to control the pH and ionic composition of this fluid.
As changing environmental conditions affect our fisheries stocks, the approaches we use to harvest and manage stocks must also be adaptable. My research focusses on the response of economically important fisheries species to climate change and ocean acidification. In particular, I am interested in how the Georges Bank Atlantic sea scallop stock will respond to ocean acidification over the 21st century, and how this will affect the fishery at both a management and socioeconomic level. By assessing the vulnerability of organisms, we can identify robust populations, and manage our marine resources accordingly.
