Temporal dynamics of copper chemistry in the shoal grass, Halodule Wrightii Aschers

Shoal grass, Halodule wrightii Aschers, is the dominant species of submerged
marine vascular hydrophyte in the Indian River Estuary, Florida. Dissolved oxygen,
temperature, salinity, pH, and redox potential or Eh measured over time gave evidence that
shoal grass has resiliency and stability in the face of a ma;or storm. Copper uptake by Halodule
leaves was measured, and translocation of Cu through the plant to roots occurred. Monitoring of
Cu in nearshore seagrass communities will directly reflect any abnormal amounts of metal into
these systems.
