PARAGON 2 - KM2209 - LISST, AC-S, and ECO

<p>These Simons Collaboration on Ocean Processes and Ecology (SCOPE) data products were produced by the University of Hawaiʻi at Mānoa with support from the Simons Foundation.</p> <p>This dataset was collected on the R/V Kilo Moana during the PARAGON 2 cruise which departed from and returned to Honolulu, HI. The cruise track was Lagrangian, following free-floating arrays deployed in a chlorophyll bloom feature. Three biooptical instruments were plumbed to the underway uncontaminated seawater (intake depth 6m). Data for each instrument were averaged to the minute and matched to a timestamp on the minute. &nbsp;LISST: &nbsp;Filtered values (&lt;0.2 um) removed from all data. The summed volume concentration of particles (in uL/L), the standard LISST output, is presented for 3 size ranges: 1.25-2 &micro;m, 2-20 &micro;m, and 20-100 &micro;m. Larger size classes are excluded due to low detection limits and scattering at density gradients. Note that data have not been processed to remove outliers. AC-S: Filtered values (&lt;0.2 um) removed from all data (see White et al., 2017, GRL); data corrected for residual temperature and scattering; AC-S chl a concentrations obtained from a Gaussian fit over absorbance spectra in the red portion of the spectrum, assuming in vivo chl-a specific absorption of 0.0203 m2/mg at 674 nm. ECO: filtered values (&lt;0.2 um) removed from chl and volume scattering data; chl fluorescence converted to mg/m3 using factory calibrations. CDOM not included due to faulty channel. Time is in UTC.</p>
