The remaining sample was parted into two equal parts (Motoda plankton splitter). One half was preserved in 4 % formaldehyde, the other part was parted into size fractions by filtering through 2000 1000 Sampling Gear Net Mesh Tow Method ( depth range ) # of Tow % of all Tows MOCNESS (Multiple Opening and Closing Nets and Environment Sampling System) 180 um step oblique down-to ~100 m 2 2.3 % MOCNESS (Multiple Opening and Closing Nets and Environment Sampling System) 180 um step oblique down-to ~500 m 31 35.2 % WP-2 (UNESCO Working Party 2) 180 um oblique down-to ~100 m 5 5.7 % WP-2 (UNESCO Working Party 2) 180 um oblique down-to ~250 m 50 56.8 %     TOTAL TOWS 88   Sub-Collection:   Trans-Atlantic Study of Calanus (TASC) COPEPOD https://www.st.nmfs.noaa.gov/copepod Web v14.1   [ 2017-Sep ]
