Phosphate time series data obtained from an autonomous programmable Flow Injection (pFI) analyzer at CeNVOOS Moss Landing Shore Station Dataset Description: Methods and Sampling: <p>We deployed a pFI analyzer at the Central and Northern California Ocean Observing System (CeNCOOS) Moss Landing shore station in February 2022. The instrument was equipped with an auxiliary diaphragm pump and sample loop for hourly phosphate analysis of samples withdrawn from the station’s seawater intake line. The samples were then analyzed using a pFI analyzer running on the assay described in Murphy and Riley (1962), adapted for pFI use.&nbsp;During this 6-day deployment, we configured the pFI analyzer to&nbsp;create a four-point calibration curve (0, 0.5, 1.5 and 3.0 µmol L<sup>-1</sup>&nbsp;PO<sub>4</sub>)&nbsp;every 12 hours using a single MQ phosphate standard (3.0 µmol L<sup>-1</sup>&nbsp;PO<sub>4</sub>). In the intervals between these calibrations, the pFI was programmed to withdraw and analyze a sample from the seawater intake line hourly.&nbsp;The calibration procedure involved aspirating a fixed volume of the concentrated standard into one of the holding coils and simultaneously dispensing a variable volume of diluent (MQ carrier) to set the appropriate dilution factor.&nbsp;</p>

Collaborative Research: Developing Automated Nutrient and Trace Metal Methodology using Programmable Flow Injection

Collaborative Research: Developing Automated Nutrient and Trace Metal Methodology using Programmable Flow Injection
<p>NSF Award Abstract:</p>
<p>Progress and discovery in the understanding of the chemical processes that regulate the growth of phytoplankton in the marine environment is limited by the ability of oceanographers to measure nutrients and trace metals at relevant spatial and temporal scales. This project aims to develop a new generation of autonomous and highly sensitive nutrient and trace metal analyzers for shipboard use and deployment at coastal monitoring stations, with potential for incorporation into existing autonomous observing platforms (e.g., gliders, autonomous underwater vehicles). Such a development will generate new insights into nutrient dynamics at a range of spatial and temporal scales and provide a new capability to obtain high resolution data sets for nutrients and trace metals in remote areas and environments where sample volumes are limited (e.g., brines, pore waters).</p>
<p>This project will develop novel automated methods for nutrients (phosphate and silicate) and trace metals (aluminium, manganese) using a technology called programmable Flow Injection (pFI). pFI is a microfluidic technique, which allows to automate conventional wet chemical analysis using microliter volumes of sample and reagents while significantly reducing the generation waste. In order to bring low levels of trace metals and nutrients that characterize remote ocean regions into the analytical window of pFI, concentration techniques will also be developed and coupled to spectrophotometric and fluorescence detection. The developed methodologies will be intercalibrated with standard oceanographic methods by participating in a GO-SHIP research cruise and a Hawaii Ocean Time-series cruise of opportunity. The long-term, unattended operation of the pFI analyzers will be evaluated at the Central California Ocean Observing System (CenCOOS) Moss Landing Shore station, where autonomous pFI analyzers will be deployed to undertake a year-long, hourly time series of phosphate and silicate. The data obtained from the shore station will be made publicly available and will complement existing monitoring data from this location, illuminating the connection between deep ocean nutrient dynamics and biological activity in coastal upwelling systems. The newly developed pFI analyzers will be assembled using commercially available components and open source software to facilitate uptake of this new methodology by the chemical oceanography community at large. This project will also support the training and exchange of at least two graduate students at the University of Hawaii at Mānoa and the Moss Landing Marine Laboratories, who will represent the next generation of specialists in the development and application of pFI methodologies to chemical oceanography.</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

<p>The pFI analyzer was calibrated every 12 hours with working phosphate standards prepared in MQ water&nbsp;(0-3&nbsp;µmol L<sup>-1</sup>). To calculate phosphate concentrations at each depth, we took the mean of the baseline corrected absorbance at 880 nm minus the reference absorbance at 1050 nm. Phosphate concentrations were then calculated using the slope and intercept of the MQ calibration curves.&nbsp;</p>
<p>The instrument was controlled and the data was processed using FloZF software (v 5.2).&nbsp;</p>

This instrument was furnished with two High Flow milliGAT pumps with stainless steel heads, a plexiglass 8-port Lab-On-Valve, a 20 cm Long Path Linear Flow cell equipped with a Tungsten-Halogen lamp and a VIS-NIR Flame spectrophotometer (Ocean Insight, USA). The instrument was controlled and the data processed using FloZF software (v 5.2). Instrument Name: Flow Injection Analyzer Instrument Short Name:FIA Instrument Description: An instrument that performs flow injection analysis. Flow injection analysis (FIA) is an approach to chemical analysis that is accomplished by injecting a plug of sample into a flowing carrier stream. FIA is an automated method in which a sample is injected into a continuous flow of a carrier solution that mixes with other continuously flowing solutions before reaching a detector. Precision is dramatically increased when FIA is used instead of manual injections and as a result very specific FIA systems have been developed for a wide array of analytical techniques.
