Gargett's research encompasses turbulence, internal waves, and the connections between mixing in the water column and biological processes. Her research on turbulence levels in shallow waters has identified Langmuir supercells, or large-scale
Langmuir circulation, that cause extensive mixing of sediment in the coastal zone. Working with biologists, She proposed the 'optimal stability window' which considered how the stability of the water column determines the relationship between fish abundance and the strength of the
Aleutian Low. The link between physics and fish explored in this paper raised questions about gaps in marine science that should be addressed in order to further research linking fisheries with physical oceanography
