The most accurate calculation of nitrate concentration from the ultraviolet (UV) absorption spectrum of seawater requires that the absorption signal due to bromide in seawater be removed before nitrate concentrations are computed. Recent work suggest

The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) program has begun deploying a large array of biogeochemical sensors on profiling floats in the Southern Ocean. As of February 2016, 86 floats have been deployed. Here the focus

Six profiling floats equipped with nitrate and oxygen sensors were deployed at Ocean Station P in the Gulf of Alaska. The resulting six calendar years and 10 float years of nitrate and oxygen data were used to determine an average annual cycle for ne

Reagent-free optical nitrate sensors [in situ ultraviolet spectrophotometer (ISUS)] can be used to detect nitrate throughout most of the ocean. Although the sensor is a relatively high-power device when operated continuously (7.5 W typical), the inst

Improvements in the data processing algorithm and calibration procedures have greatly increased the accuracy of nitrate measurements using an in situ ultraviolet spectrophotometer (ISUS). Two major changes in the algorithm involve application of a te

N2 fixation has been understudied in marine environments outside of the subtropical and tropical oceans and where water temperatures are typically below 20–25uC. We identified nifH phylotypes and measured N2 fixation rates under ambient conditions

Flow injection analysis with chemiluminescence detection (FIA–CL) via the reaction of copper with 1,10-phenanthroline was used for the determination of copper complexation in seawater. A detection limit of 0.1 nM Cu in undiluted seawater without sa

During the second leg (PlumEx) of the 1993 IRONEX cruise, the partial pressure of CO 2 and the concentrations of nitrate and silicate in the surface waters around the Galapagos Islands were continuously measured using automated underway systems. Base

Uncertainty concerning the cycles and budgets of the major bioactive chemicals in the sea is partially a function of undersampling in relation to the actual spatial and temporal variability. However, technologies are becoming increasingly available f
