Effects of Urban Land Use on Tidal Creeks

Madeline Wedge, who earned her Master’s degree from Auburn University, shares her research on the effects of urban land use on tidal creek salinity, and its impact on the fish community found in adjacent salt marshes. She used HOBO U24 Conductivity Data Loggers from Onset to measure temperature and salinity conditions in the creeks.

Here are some of the highlights of the study:

  • Conductivity loggers allowed for measurements over a whole year instead of one-time captures of salinity
  • Urban tidal creeks demonstrated more rapid changes in salinity in response to rain events compared to reference marshes
  • Changes in salinity were related to changes in the fish community
