Intact phospholipid and fatty acid compositions in the digestive system of Antarctic krill, Euphausia superba, sampled in January, March and May ...
This dataset contains the seasonal composition of intact phospholipids as well as of free fatty acids from the digestive system of Antarctic krill, Euphausia superba. Krill was caught with a continuous krill pumping system in May of 2021 in the Bransfield Strait and in January and March of 2022 at t...

The stomach, digestive gland and hind gut were dissected and analysed individually. Samples were extracted with an optimized Bligh&Dyer protocol.
