My lab’s research is motivated by the rapidly warming and changing conditions in high-latitude seas. Our work spans the fields of underwater acoustics, physical oceanography, and polar science and combines active acoustic observations with in-situ measurements and theoretical acoustic scattering models to quantify changes occuring coastal waters. This includes the study of marine-terminating glaciers, thermohaline structure, gas bubbles, and fluid emissions. One of our current objectives is to better quantify the interactions between the marine and terrestrial systems at the ice-ocean interface of marine-terminating glaciers.

Other ongoing research topics include:

1) The development of autonomous platforms for high latitude active acoustic data collection

2) Remotely quantifying heat flux from hydrothermal vent systems

3) Exploring the connection between active fault zones and seafloor methane emissions

4) The impact of intense stratification and low-oxygen conditions on fish populations
