New: Effect of body size on drag
Cluster Drag
Small changes to existing Cd analysis
PCA
Argos sightings analysis

Interference Drag Calcs

 - calculate boundary layer along individual of specific length, with
widths (bodywidth.m) based on C.A. Miller
 - information on where entanglement attachment points are, their area,
and their height
 - calculate interference drag coefficient
gear-specific variable names

to reduce confusion between gearRe and whaleRe, gearCd and whaleCd
Changed speeds, added submergence

highest speed 2.5 m/s because this is the upper limit of drag
measurements.
added submergence differences, wrote up methods.
