To address these questions, we are doing survey work to map out the distribution of the krill and their predators. For the krill, we have a number of different instruments to map them, including two kinds of echosounders (multi-frequency and broadband), a video system, as well as a plankton net. Then to understand the krill's physical environment, we have a Conductivity-Temperature-Depth (CTD) instrument to measure the salinity and temperature of the water, as well as an Acoustic Doppler Current Profiler (ADCP) to measure currents. And finally for the higher predators, we have two marine mammal observers and one bird observer. All told we have a lot of gear -- just getting the instruments to the ship required a 20 foot truck!
Over the next few days, myself and others in our team will be posting about what we're learning and life at sea. Stay tuned!
