| Study Title | Metabolomic analysis of particulate matter in the NPSG during a 2017 cruise on the R/V Kilo Moana as part of the MESOSCOPE program |
| Study Summary | Targeted and untargeted analysis of metabolomics samples from the North Pacific Subtropical Gyre taken during the 2017 June/July SCOPE cruise on the R/V Kilo Moana (KM1709) across a mesoscale eddy dipole, with high-resolution depth profile sampling across the DCM in the center of each eddy. Particulate matter was collected on 0.2um filters and extracted using a modified Bligh & Dyer before analysis on a QE Orbitrap. Results show significant changes in the absolute quantity and relative composition of particles in the gyre between anticyclonic and cyclonic eddies. |

| MS Comments: | Metabolomic data was collected on a Thermo Q Exactive HF hybrid Orbitrap (QE) mass spectrometer. The capillary and auxiliary gas heater temperatures were maintained at 320°C and 100°C, respectively. The S-lens RF level was kept at 65, the H-ESI voltage was set to 3.3 kV and sheath gas, auxiliary gas, and sweep gas flow rates were set at 16, 3, and 1, respectively. Polarity switching was used with a scan range of 60 to 900 m/z and a resolution of 60,000. Calibration was performed every 3-4 days at a target mass of 200 m/z. All files were then converted to an open-source mzML format and centroided via Proteowizard’s msConvert tool. Skyline was used to for manual integration and QC of quantified data, while XCMS was used with a custom QC method for peak area data and each feature manually reviewed. |
