| 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. |

| Collection ID: | CO002888 |
| Collection Summary: | Samples were collected aboard the R/V Falkor in March and April 2018. Water was collected with Niskin bottles attached to the CTD from the surface and the deep chlorophyll maximum (DCM) in both the morning (~6AM) and evening (~6PM). Water was filtered onto a 0.2um pore size filter under gentle vacuum pressure prior to flash-freezing in LN2 before storage at -80 in precombusted aluminum foil. Samples were collected from two locations, one in a cyclonic eddy (-13cm, stations 62 and 64) and one in an anticyclonic eddy (+20cm, stations 77 and 80) three days apart. |
