In some previous studies, the ratio between a di-unsaturated highly branched isoprenoid (HBI) lipid termed IPSO 25 and a structurally related tri-unsaturated counterpart (HBI III) (viz. IPSO 25 /HBI III) has been used as a proxy measure of variable sea ice cover in the Antarctic owing to their produ...
