Highly branched isoprenoids (HBIs) are diatom-produced lipids which are used as biomarkers to track pelagic and sympagic (ice-associated) carbon in the Arctic environment. HBIs were measured in pelagic particulate organic matter (POM), sediment and faunal samples collected aboard the R/V Kronprins Haakon on the Northeast Greenland shelf, in August and September 2022 as part of the UiT-led TUNU programme. HBIs were extracted and then measured with a Shimadzu QP-2020 GC-MS. An internal standard was added to each sample prior to extraction to confirm appropriate extraction. HBI spectral intensities were used to calculate the H-Print, a ratio of 3 target HBIs. For faunal samples, the H-Print was used to calculate the proportion of carbon assimilated by fauna which originated from sympagic production.
