These data were collected as part of a project measuring hydrodynamic drag forces on submerged Australian trees. Two tree types were used in the experiments: sheoak and tea tree. The following symbols are used:
- prefix 'CG' in specimen refers to a sheoak (*Casuarina glauca*)
- prefix 'CC' in specimen refers to a sheoak (*Casuarina cunninghamiana*)
- prefix 'MB' in specimen refers to a tea tree (*Melaleuca bracteata*)
