SPCs were set up at two different heights. One was installed at the center of the compass deck, and the other was installed on the starboard of the bridge deck. The processor divides the particles into 32 classes depending on their diameters. The categories are shown in a table of the first tab. In the data files, each tab snows a daily data, and the numbers of particles in each class are listed every second. The data of SPCs, were obtained continuously through the cruise from Aug. 22 to Oct. 2.
Please mention that this cruise was conducted under the Arctic Challenge for Sustainability (ArCS) Project, which was funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT).
spray particle counter (SPC-S7; Niigata Denki)
The SPC (SPC-S7; Niigata Denki), which was originally developed for the measurement of drifting snow, was improved to be a seawater spray particle counter. The flux distribution and the transport rate can be calculated as a function of particle size. The sensing area of SPC is 25 mm wide and 3 mm high, and the measuring range is set from 100 to 1,000 µm in diameter.
