sensitivity of larval and juvenile sand lance on stellwagen bank to predicted ocean warming, acidification, and deoxygenation


Sand lance (Ammodytes dubius) are small forage fish that are thought of as the 'backbone' of Stellwagen Bank National Marine Sanctuary, which is home to humpback whales, seals, bluefin tuna, and a variety of marine birds experiencing ocean and climate change. Scientists will analyze how this important fish species will  grow and survive under increased temperature and carbon dioxide (CO2) and lower oxygen (O2) conditions, similar to those predicted for the future. 

This work will allow researchers to see which combinations of these stressors will have the largest impacts on the growth of young sand lance. The research will also evaluate the effect of these stressors on swimming behavior of young fish, including their ability to detect light and depth in the water column. Additionally, this effort will provide a clearer view of ocean changes that are currently taking place in this extremely rich and diverse ecosystem.
