PUPCYCLE II Day 3 – Holey Socks? – Science by the Sea

The aim of this chapter is to introduce the reader to the breadth of techniques and methods currently available to study the biogeochemical cycles of trace metals and their

Marine Biogeochemical Cycles

Phosphorus availability has influenced the co-evolution of life and Earth’s environments. While phosphate was likely the main phosphorus source for life during the

This Virtual Special Issue (VSI), Cycles of trace elements and isotopes in the ocean – GEOTRACES and beyond, consists of 31 chemical oceanographic studies concerning the

We present here baseline measurements of colloidal (∼0.003–0.200 μm) iron (Fe), zinc (Zn), nickel (Ni), copper (Cu), cadmium

Bioactive trace metals (such as Fe, Zn, and Cu) as life-sustaining nutrients are important in regulating biogeochemical cycles of carbon and macronutrients (nitrogen,

The Biogeochemical Cycles of Trace Metals in the Oceans

Constraining Southern Ocean trace metal biogeochemical cycling is therefore important not just for understanding biological productivity and carbon cycling regionally, but

Ocean biogeochemical processes cycle the major elements of life—carbon, nitrogen, oxygen, phosphorus, and sulfur—along with key micronutrients and vitamins. These biogeochemical

Planktonic uptake of some essential metals results in extraordinarily low concentrations in surface seawater. To sequester or take up these micronutrients, various

We begin this chapter by discussing what we know of the concentrations of trace elements in marine microorganisms and of the relevant mechanisms and kinetics of trace-metal uptake.

Trace metal limitation not only affects the biological function of organisms, but also the health of ecosystems and the global cycling of elements. The enzymatic machinery of

Changes in the ocean temperature, seawater acidity, and oxygen level are parts of global change that may indirectly impact the biogeochemical cycles of trace metals in the

GEOTRACES: The Marine Biogeochemical Cycle of Trace

The biogeochemical cycles of trace elements and their isotopes (TEIs) constitute an active area of oceanographic research due to their role as essential nutrients for marine organisms and their

The Laboratoire des Sciences de l’Environnement Marin at the Université de Bretagne Occidentale (UBO) in Brest, France, invites applications for a Postdoctoral Research

The distribution of trace metals in the regions of the Southern Ocean studied here highlight the importance of biologically-driven cycles; however, latitudinal differences were as

GEOTRACES is an international study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs), designed by marine geochemists to accelerate TEI research under a

micronutrient influencing global biogeochemical cycles in the oceans (Moore et al., 2002) and the potential role of other trace metals such as zinc. In particular, there is a pressing need for an

The GEOTRACES program, an international study of marine biogeochemical cycles of trace metals and their isotopes (TEIs), has recently started to identify processes and

We then review the biochemical role of trace elements in the marine cycles of carbon, nitrogen, phosphorus, and silicon. Using this information, we examine the evidence, emanating from

Trace metals in the ocean have the potential to control the biological structure of the ocean. Many of them, particularity the transition metals such as Fe, Ni, Cd, Co, Cu or Mo,

Trace metals shape both the biogeochemical functioning and biological structure of oceanic provinces. Trace metal biogeochemistry has primarily focused on modes of external

Connecting Trace Metals to the Global Carbon Cycle. A key driver of research on micronutrients is their potential role in regulating the ocean carbon cycle via their impact on

Trace elements in seawater can be limiting factors of biological productivity, tracers of ocean circulation and biogeochemical processes, and proxies for paleoceanography.The
