Daytime-dependent abundance of Salpa thomsponi during RV Tangaroa cruise TAN1810 to the Chatham Rise, New Zealand

Daytime-dependent abundance changes of Salpa thomsponi within the top 200 m of the water column were studied at the Chatham Rise, New Zealand in October 2018 using oblique Bongo net tows (202 µm mesh size, 0.4 m² mouth opening). Specimens were identified to life cycle stage (blastozooid, oozooid) an...

Description
Summary:Daytime-dependent abundance changes of Salpa thomsponi within the top 200 m of the water column were studied at the Chatham Rise, New Zealand in October 2018 using oblique Bongo net tows (202 µm mesh size, 0.4 m² mouth opening). Specimens were identified to life cycle stage (blastozooid, oozooid) and measured for oral-atrial length. Differences in life cycle stage and length-frequency distribution patterns were compared among three consecutive days and nights.
