Absorption coefficients by total particles (ap) were measured on water samples collected from underway AC-S flow-through system outflow and CTD. Measurements were performed using a dual-beam UV/VIS spectrophotometer as described in Liu et al. (2018) and Liu et al. (2019).1. About sampling:a) underway samples were collected from unfiltered AC-S outflow (depth: 11m); CTD samples with 5-6 depths were collected on upcast.b) vacuum pressure for filtration: maximum 200 hPac) samples were shock frozen in liquid nitrogen and then stored in -80°C until measurement after cruise.d) blank filters were collected by soaking them in 0.2um filtered seawater.e) replicates were not collected.2. About measurements:a) Instrument: dual-beam UV/VIS Spectrophotometer (Cary 4000, Varian Inc., Palo Alto, CA, USA) equipped with a 150 mm integrating sphere (external DRA-900, Varian, Inc. and Labsphere Inc., made from Spectralon (TM)).b) wavelength range of scan and resolution: 300-850 nm, 1 nm.c) slit band width: 2 nm.d) scan speed: 150 nm min−1e) Sample filters were extracted with 95% methanol for the absorption measurement of NAP.f) The baseline of the spectrophotometer was set with a dry piece of a blank filter. Filters were wetted with purified water and measured regularly after every fifth sample filter served as references.3. About data analysis:a) interpolated wavelength range and resolution: 350-750 nm, 1nm.b) pathlength amplification factor (beta correction factor): 4.5 (Röttgers and Gehnke 2012; Röttgers et al., 2014).c) Null-point scattering correction at 750 nm is applied.
