Iron (Fe) is an essential micronutrient for phytoplankton growth, but its scarcity in seawater limits primary productivity across much of the ocean. Most dissolved Fe (DFe) complexed with Fe-binding organic ligands, a poorly constrained fraction matter (DOM), which increase residence time and impact bioavailability. Here, we present conditional concentration (L ) binding-strength (log <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"...
The high N 2 fixation rate observed in the Lau Basin of western tropical South Pacific Ocean (WTSP) is fueled by iron (Fe) released from shallow hydrothermal systems. Understanding Fe bioavailability crucial but controls on stability and inputs are still poorly understood. Here, we provide new data spatial vertical distribution soluble ubiquitous humic-like ligands (L FeHS ) their associated dissolved (DFe) WTSP, including samples near vents. Our show that L heterogenous with binding sites...
Abstract The low‐molecular‐weight (LMW) reduced sulfur substances (RSS) composition of dissolved organic matter (DOM) was examined along the GEOTRACES US‐GP15 section in Pacific Ocean. We demonstrate that LMW RSS constitutes a significant fraction nonvolatile (DOS). While thiols such as glutathione were below our detection limit (300 pM), containing two carbon (C) (S) bonds present at concentrations hundreds nM range. accumulation observed subtropical waters. most likely source these is...
