Southern Ocean eDNA metabarcoding raw sequencing data, collected on the Aurora Australis 2019-2020
Progress Code: onGoing Purpose The purpose of this work is to determine best eDNA metabarcoding approaches to survey the Southern Ocean (SO). This includes comparisons of sampling strategy (2 L / 0.45 μm pore size filter vs 12 L / 20 μm pore size filter), PCR methodology (two step, dual MID tags vs...
