Author contributions
DJJ led the design of the study along with SLJ, with assistance from
MJE, who organized trace metal sampling operations for ACE Leg 1 &
IN2018V_02 and all operations for IN2018V_04, BST & DCO, who designed
and conducted the shipboard incubations, and ANA, who planned coring
operations and conducted sediment and pore water sampling for cruise
IN2018V_04. DJJ conducted seawater sampling, processed, and analyzed
samples from ACE Leg 1, IN2018V_02, IN2018V_04, and Line P cruise
2012-13. SLJ conducted sampling for ACE Leg 2. DJJ processed and
analyzed samples from DY110 and ACE Leg 2. MJE assisted in seawater
sampling for ACE Leg 1, IN2018V_02 and IN2018V_04. BT and DO analyzed
particulate samples from IN2018V_04 regeneration experiments. PN
processed and analyzed samples from M77/4. DJJ and DG processed and
analyzed samples from GP13. DJJ led interpretations and writing, and all
authors contributed to the manuscript.
