Neutral lipid fatty acids from pyrosome carcasses collected during SONNE cruise SO242/2

During RV SONNE cruise SO242/2 (September 2015) to the DISCOL site in the Peru Basin (SE Pacific), pyrosome carcasses were collected at the seafloor. Aboard, these carcasses were stored frozen and in the lab on land, they were freeze-dried and ground to fine powder. Neutral lipid-derived fatty acids (NLFAs) in pyrosome tissue were extracted following the Bligh and Dyer method and their isotopic compositions and concentrations were measured on a gas chromatograph coupled with an isotopic ratio mass spectrometer (EA-c-IRMS).
