Post-diapause Neocalanus flemingeri females morphometric measurements and calculations of lipid fullness and lipid volume taken from the R/V Sikuliaq and the R/V Tiglax in the Northern Gulf of Alaska from 2019-06-30 to 2019-09-13

Abstract

Morphometric data on Neocalanus flemingeri females were made on individuals collected in diapause in June and September, 2019 and after incubation in the laboratory for up to 4.5 weeks. Collections were made from depth in Prince William Sound in the Gulf of Alaska during two NGA LTER cruises. After sorting, females were incubated in flasks at 4-6ºC for up to 4.5 weeks. Individuals were removed for imaging and experimental incubations to study oocyte production. Morphometric analysis was used to measure prosome length and area as well as lipid sac area for lipid fullness and lipid volume calculations. Lipid consumption during diapause was minimal and modest initially.
