Measurements of the salp Pyrosoma atlanticum, RV Investigator voyage IN2017_V04, Tasman Sea, Australia (2017)

As pyrosomes migrate vertically to 800 m daily, they have the potential to transport the carbon they consume at the surface to these depths. In the austral spring of 2017, a Pyrosoma atlanticum swarm was smpled in the Tasman Sea. Maximum biomass of pyrosomes was 360 mg WWm3, and pyrosomes were able to consume the majority (95%) of the phytoplankton community while at the surface.
