Study TitleMetabolomic analysis of particulate matter in the NPSG during a 2017 cruise on the R/V Kilo Moana as part of the MESOSCOPE program
Study SummaryTargeted 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.

Collection ID:CO002889
Collection Summary:Samples were collected aboard the R/V Kilo Moana in June and July 2017. Water was collected with Niskin bottles attached to the CTD from the surface and the deep chlorophyll maximum (DCM), and 175 meters depth. 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 in two stages, the first of which was a transect across the entire eddy dipole from one edge to another while the second stage was a long-term Lagrangian occupation of the eddy centers (L1 = cyclone @ -12cm, L2 = anticyclone @ +25cm). Samples for the transect were collected throughout the day while the eddy center samples were all collected at about 6pm.
