CT001:
Abiotic and Biotic Retention, Recycling, and Remineralization of Metals in the Ocean


Session ID#: 23502

Session Description:
Trace metals shape both the biogeochemical functioning and the biological structure of oceanic provinces, and considerable insight into trace metal distributions have been gleaned from international programs like GEOTRACES. To date, observational and modelling efforts have mainly focused on modes of external metal supply from different sources. While this has yielded important advances, we also know that metals undergo key internal transformations such as biotic uptake, scavenging, recycling, and remineralization. These internal transformations play crucial roles in shaping the biogeochemical cycling of metals by governing their bioavailability, oceanic distributions, and residence times. In this session we solicit presentations that address key questions regarding the abiotic and biotic processes regulating (i) the retention timescale for metals in the upper ocean, (ii) surface ocean metal recycling and bioavailability, (iii) the subsurface regeneration length scales for metals in the ocean interior, and (iv) the role of mineral versus organic characteristics of sinking particles on metal scavenging. We also seek presentations that provide insights into how these key questions are mediated by differing physico-chemical and microbial processes in contrasting ocean settings. Presentations showing insights from the diverse standpoints of biogeochemical oceanography and molecular ecology, from both observational and modelling perspectives, are strongly encouraged.
