Article
Full-text available
Nickel is a biologically essential element for marine life, with the potential to influence diverse processes, including methanogenesis, nitrogen uptake and coral health, in both modern and past oceans. However, an incomplete view of oceanic Ni cycling has stymied understanding of how Ni may impact marine life in these modern and ancient oceans. He...
Article
The importance of iron as a limiting nutrient in the open ocean is widely recognized, but there is substantial uncertainty about the rate that it cycles in the marine environment. Here, we combine measurements from the water column, sediment traps, and incubations to constrain Fe turnover during summer at Station ALOHA in the North Pacific Subtropi...

Trichodesmium, a major diazotroph in tropical and subtropical oceans, provides a significant amount of bioavailable nitrogen in oligotrophic oceans. Remarkably, the cyanobacteria carry out nitrogen fixation and photosynthesis simultaneously under high light (HL) conditions. Here, we hypothesize that nickel superoxide dismutase (NiSOD) protects the...
Article

Marine oxygen deficient zones (ODZs) promote unique plankton communities and redox environments which impact the cycling of biologically essential trace metals in the ocean. Here we use measurements of dissolved and particulate Ni concentrations and isotopes to investigate the biotic and abiotic processes controlling Ni cycling in the world’s large...

The Thomas Fire began on December 4, 2017 and burned 281,893 acres over a 40-day period in Ventura and Santa Barbara Counties, making it one of California's most destructive wildfires to date. A major rainstorm then caused a flash flood event, which led to the containment of the fire. Both airborne ash from the fire and the runoff from the flash fl...

Full-text available
Nickel and copper are cofactors in key phytoplankton enzymes and the stable isotope composition of Ni and Cu (δ⁶⁰Ni and δ⁶⁵Cu) in seawater have the potential to identify major processes that influence their biogeochemistry. However, accurate analysis of δ⁶⁰Ni and δ⁶⁵Cu is challenging because of the difficulties in separating these metals from inter...
Article
Full-text available
The 2018 eruption of Kīlauea was associated with massive input of molten lava into the coastal ocean, which altered seawater chemistry and increased phytoplankton production. In seawater plumes advected away from the site of lava entry, we observed elevated concentrations of over a dozen metals relative to background seawater and unique isotopic co...
Preprint
Nickel and copper are cofactors in key phytoplankton enzymes and the stable isotope composition of Ni and Cu (δ60Ni and δ65Cu) in seawater have the potential to identify major processes that influence their biogeochemistry. However, accurate analysis of δ60Ni and δ65Cu is challenging because of the difficulties in separating the metals from interfe...
Article
Full-text available
We determined Zn isotope composition (δ⁶⁶Zn) in the water column of the Northwestern Pacific Ocean (NWPO) and its marginal seas to investigate the processes driving vertical and spatial variations. Comparable to previous studies, dissolved δ⁶⁶Zn was relatively low in the top 200 m, ranging from −0.91 to +0.24‰ and increased with depth toward an ave...
Article
The isotopic composition of iron, zinc, copper, and cadmium (δ56Fe, δ66Zn, δ65Cu, and δ114Cd) are novel and promising tools to study the metabolism and homeostasis of trace metals in the human body. Serum δ65Cu has been proposed as a potential tool for diagnosis of cancer in liquid biopsy, and other metals may have similar utility. However, accurat...
Article
We measured dissolved and particulate Cd isotopic composition in the water column of a meridional transect across the Kuroshio-Oyashio Extension region in a Japanese GEOTRACES cruise to investigate the relative influence of physical and biogeochemical processes on Cd cycling in the Northwestern Pacific Ocean. Located at 30–50°N along 165°E, the tra...
Article
The surface water of the Western Philippine Sea (WPS) receives a significant amount of anthropogenic aerosols from East Asia, serving as an ideal location to investigate the impact of anthropogenic aerosol deposition on trace metal composition and cycling in the Northwestern Pacific Ocean (NWPO). As part of the Taiwan GEOTRACES process study, we ha...
Article
Full-text available
To acquire appropriate iron (Fe), vascular plants have developed two unique strategies, the reduction-based strategy I of nongraminaceous plants for Fe(2+) and the chelation-based strategy II of graminaceous plants for Fe(3+) . However, the mechanism of Fe uptake in bryophytes, the earliest diverging branch of land plants and dominant in gametophyt...
Article
We determined the Cd isotopic composition of size-fractionated phytoplankton, zooplankton and sinking particles collected in the top 160 m of a deep water time series station in the South China Sea (SCS) to investigate the fractionation effects of major biotic activities. The isotopic composition (ε114/110Cd = [(114Cd/110Cd)sample / (114Cd/110Cd)NI...
Thesis
Full-text available
In this study, we determined the Cd isotopic composition in seawater, suspended plankton, and sinking particles of the South China Sea (SCS) to better understand the relative contributions of biotic and abiotic processes that control Cd cycling in the ocean. The isotopic composition in the water column decreased with depth, with ε114/110CdNIST valu...

Full-text available
The dissolved concentration and isotopic compositions of cadmium (Cd) in the seawater of the West Philippine Sea (WPS) were determined. In general, Cd isotopic composition in the water column decreased with depth, with ε114/110Cd (ε114/110Cd = [(114Cd/110Cd)sample/(114Cd/110Cd)NIST3108 − 1] × 104) ranging from +7.2 to +10.1 in the top 60 m, from +4...

Hyperaccumulators tolerate and accumulate extraordinarily high concentrations of heavy metals. Content of metal-chelator nicotianamine (NA) in the root of zinc (Zn) hyperaccumulator Arabidopsis halleri is elevated in comparison to non-hyperaccumulators, a trait that is considered to be one of the markers of a hyperaccumulator. Using metabolite prof...
Article
Our previous study has shown that the Cd isotopic composition in the surface water and the sinking particles in the South China Sea (SCS) are identical at ε114/110Cd ∼ +9. Therefore, net biological isotopic fractionation of Cd in the surface water was insignificant (Yang et al., 2012). Using a box-model calculation, Murphy et al. (2014) suggested t...
Article
We determined the Cd isotopic composition of seawater and sinking particles collected in the deep basin of the northern South China Sea (SCS) to investigate the controlling mechanisms on the Cd isotopic composition in the water column. The isotopic composition in the water column decreased with depth, with ε114/110Cd values (ε114/110Cd = [(114Cd/11...
