Environmental parameters of iron-enriched sediments at LTER HAUSGARTEN during POLARSTERN cruise PS93 ...
Impact of Local Iron Enrichment on the Small Benthic Biota in the deep Arctic Ocean The study assesses the impact of local iron enrichment on the small benthic biota (bacteria, meiofauna) together with environmental parameters indicating the input of food at the deep seafloor. To evaluate the hypoth...
