Pathways of superoxide (O 2 - ) decay in the Eastern Tropical North Atlantic
Superoxide (O 2 : IUPAC name dioxide (1−)) is an important transient reactive oxygen species (ROS) in the ocean formed as an intermediate in the redox transformation of oxygen (O 2 ) into hydrogen peroxide (H 2 O 2 ) and vice versa. This highly reactive and very short-lived radical anion can be prod...

Superoxide (O 2 : IUPAC name dioxide (1−)) is an important transient reactive oxygen species (ROS) in the ocean formed as an intermediate in the redox transformation of oxygen (O 2 ) into hydrogen peroxide (H 2 O 2 ) and vice versa.
