Vertical day-night distribution of the salp Soestia zonaria in the temperate Northeast Atlantic and the Southwest Pacific over the Chatham Rise

Although the oceanic widespread pelagic tunicate Soestia zonaria has been studied for more than a century, little ecological information exists. Soestia primarily occurs in tropical to warm-temperate regions. Soestia specimens were collected between 2015 and 2021 during three research expeditions (E...

Description
Summary:Although the oceanic widespread pelagic tunicate Soestia zonaria has been studied for more than a century, little ecological information exists. Soestia primarily occurs in tropical to warm-temperate regions. Soestia specimens were collected between 2015 and 2021 during three research expeditions (EXPORTS cruise to the Northeast Atlantic and TAN1516 and TAN1810 over the Chatham Rise, New Zealand) using MOCNESS-1 net and large midwater trawl with maximum sampling depths of 1000 m. More than 530 Soestia specimens (oral-atrial length: 4–68 mm) were analysed for their vertical distribution, i.e., weighted mean depths (WMD) during the day and night, and migration distance.
