Dissolved copper binding ligands from seawater samples during POLARSTERN cruise PS100/ GN05 (ARK-XXX/2) ...
Copper (Cu) is a bio-essential trace metal involved in many phytoplankton metabolic processes. In seawater, its bioavailability is controlled by the formation of organic complexes with binding ligands which also controls the toxicity of free cupric ion (Cu²⁺). Despite this key role, information abou...

Copper (Cu) is a bio-essential trace metal involved in many phytoplankton metabolic processes. In seawater, its bioavailability is controlled by the formation of organic complexes with binding ligands which also controls the toxicity of free cupric ion (Cu²⁺). Despite this key role, information about Cu speciation is scarce, especially in the Arctic Ocean. However, this oceanographic region is essential to understand the copper biogeochemical cycle. This dataset contains the results of Cu complexation measurements in station depth profiles sampled in Fram Strait and Greenland Shelf.
