AB  - Plastic debris in the coastal environment is subject to complex and poorly 
      characterized weathering processes. To better understand how key environmental 
      factors affect plastic degradation in a coastal zone, we conducted an in situ 
      experiment. We deployed strips of high density polyethylene (HDPE) and 
      polystyrene (PS) in paired coastal areas of contrasting conditions (hydrodynamic 
      activity: erosional or depositional; water depths: subtidal or intertidal). 
      Strips were collected after environmental exposures at 4, 8, and 43 weeks and 
      analyzed for change in mass, algal biofilm growth, and imaged by petrographic and 
      electron microscopy (SEM-EDS). Significant surface erosion was evident on both 
      polymers, and was more rapid and more extensive with PS. Degradation of PS was 
      responsive to intensity of hydrodynamic activity, and was greater at intertidal 
      depths, highlighting the critical role played by photo-oxidation in the coastal 
      zone, and suggesting that algal biofilms may slow degradation by playing a 
      photo-protective role.
