Organic dissolved iron (dFe)—binding ligands were measured by competitive ligand exchange—adsorptive cathodic stripping voltammetry (CLE‐ACSV) at multiple analytical windows (side reaction coefficient of salicylaldoxime, α Fe(SA) 2 = 30, 60 and 100) in surface benthic boundary layer (BBL) samples along the central California coast during spring summer. The weakest detected BBL lowest window with average log K cond FeL,Fe' 10.2 ± 0.4 summer 10.8 0.2 spring. Between 3% 18% dFe complexation was...
Abstract. Organic measurements, such as biological oxygen demand (BOD) and chemical (COD) were developed decades ago in order to measure organics water. Today, these time-consuming measurements are still used parameters check the water treatment quality; however, time required generate a result, ranging from hours days, does not allow COD or BOD be useful process control – see (1) Standard Method 5210 B; 5-day Test, 1997, (2) ASTM D1252; 2012. Online organic carbon monitoring allows for...
As part of a rapid response cruise in May 2006, we surveyed water column hydrothermal plumes and bottom conditions on the East Pacific Rise between 9°46.0′N 9°57.6′N, where recent seafloor volcanic activity was suspected. Real‐time measurements included temperature, light transmission, salinity. Samples plume waters were analyzed for methane, manganese, helium concentrations, δ 13 C methane. These data allow us to examine effects 2005–2006 eruption(s) chemistry. Methane manganese are...
