Data_Sheet_1_Pelagic Amphipods in the Eastern Fram Strait With Continuing Presence of Themisto compressa Based on Sediment Trap Time Series.docx
Pelagic amphipods represent a large fraction of organisms entering sediment traps as so-called “swimmers.” These swimmers were sampled with sediment traps (∼200–300 m water depth) with two mooring arrays deployed at two different positions in the Long-Term Ecological Research observatory HAUSGARTEN...
