Large Whale Biology Survey (DE9908, EK500)

The large whale biology survey primarily focuses on right whales in the coastal and continental shelf areas, with the following objectives: 1) Develop a better understanding of whale habitat use and site fidelity for abundance and monitoring of critical areas, 2) Determine the distribution and relative abundance of plankton and prey species, 3) When possible, collect identification photographs and biopsy samples.
