Some Relations Between Zooplankton and Bunker C Oil in Chedabucto Bay Following the Wreck of the Tanker <i>Arrow</i>

Abstract

Zooplankton ingested small particles of oil that were found dispersed throughout the water column in Chedabucto Bay following the wreck of the tanker Arrow. As much as 10% of the bunker C in the water column was associated with zooplankton and their feces contained up to 7% bunker C. The oil had no apparent effect on the organisms. In addition to the particulate oil which was exported from the bay by hydrodynamic processes, perhaps 20% more was sedimented to the bottom as zooplankton feces.
