Study Title | Metabolomic analysis of particulate matter in the NPSG during a 2018 cruise on the R/V Falkor |
Study Summary | Targeted and untargeted analysis of metabolomics samples from the North Pacific Subtropical Gyre taken during the 2018 March/April SCOPE cruise on the R/V Falkor (FK180310) across a mesoscale eddy dipole. 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. |

Sample Preparation:
Sampleprep ID: | SP002901 |
Sampleprep Summary: | Polar metabolites were extracted using a modified Bligh−Dyer extraction using 1:1 methanol/water and dichloromethane. A methodological blank was extracted and analyzed alongside. Isotope-labeled internal standards were added both before and after the extraction for all samples, blanks, and pooled samples. To evaluate the effect of obscuring variation due to different matrix strengths and analytical drift, pooled samples were run at both full and half concentration (diluted with water) three times during the run. |
Processing Storage Conditions: | On ice |
Extraction Method: | Bligh-Dyer |
Extract Storage: | -80℃ |
