Professor McKinley and her research group study how physical structures and biogeochemical processes in large water bodies influence carbon cycling and its temporal variability. This requires an interdisciplinary approach across a range of fields: from fluid dynamics to aquatic chemistry and ecology. She uses numerical models, historical datasets, and remote sensing in her research. Currently, Professor McKinley has projects underway addressing global trends in surface ocean pCO2, biological export of carbon from the surface to deep ocean, and productivity changes since the late 1990's in the North Atlantic. In the Great Lakes, she is investigating the potential for ocean acidification to impact the lakes, and the impacts of invasive mussels on biogeochemical cycling.
Alexis Santos completed her MS in Atmospheric and Oceanic Sciences in May 2014. Her thesis is titled Chlorophyll a Variability Due to Large-scale North Atlantic Circulation Changes.
Professor McKinley gave a seminar entitled Natural Variability and Anthropogenic Trends in the Ocean Carbon Sink at Lamont-Doherty Earth Observatory of Columbia University in March 2013. Watch it on video.
In December 2013, Professor McKinley participated in a forum entitled “Climate Change: What It Means for Wisconsin’s Economy and Natural Resources”, at the invitation of Representatives Fred Clark (D-Baraboo) and Jeff Mursau (R-Crivitz). This was a valuable opportunity to share the latest science on climate change and its impacts with state law makers.
