| Copepod species abundances from MOCNESS tows from R/V Thomas G. Thompson and R/V Malcolm Baldridge cruises in the Arabian Sea from 1994-1995 (Arabian Sea project, Arabian Sea Diapausing Copepods project) | The 1m2 MOCNESS system carries nine nets and is designed to fish with a 1m2 net mouth area when towed at a 45o angle (Wiebe et al., 1976). A flow meter mounted on the frame, just ahead of the net mouth, allowed calculation of the volume of water sampled (Wiebe et al., 1976). The data-acquisition software used angle information when calculating volume of water filtered. The 1m2 MOCNESS was fitted with 153um mesh nets and included, in addition to the standard conductivity (Sea-Bird SBE 4) and temperature (Sea-Bird SBE 3) sensors, a transmissometer (SeaTech, 25cm beam) and an oxygen probe (Sea-Bird SBE 13). The 1m2 MOCNESS was towed behind the ship at a speed of 1.5 to 2 knots (2.8-3.7 km h-1) through the water. Winch speed generally ranged from 10 to 25 m min-1 during deployment and 5 to 15 m min-1 during recovery. Target sampling depths for this report were 1000-750m, 750-500m, 500-250m, 250-200m, 200-150m, 150-100m, 100-50m, and 50-surface.

| Abundances of copepod species in each net from MOCNESS tows in the Eastern Tropical North Pacific collected on four research cruises from 2007-2017 | The first two cruises used the classic MOCNESS with its standard deck unit and sensors. The two later cruises used an upgraded MOCNESS with a Sea-Bird 911CTD for sensors and modified software. (See Wishner et al. (2020) for more details.)

| CTD data collected from MOCNESS hauls on R/V Oceanus and R/V New Horizon in the western North Atlantic from 2011-2012 (OAPS project) | The MOCNESS was equipped with eight 150-um mesh nets (nets 1-8; borrowed from URI) and one 333-um mesh net (net 0). The underwater unit used was #169. In addition to the standard temperature and conductivity probes the system also had a beta-type strobe-light unit for reducing avoidance of the nets by some zooplankton and possibly small fish. The strobe system has two units each with 12 LED sets (LUXEON Rebel LED) with peak output between 490-520 nm. Seven of the 24 LED sets were no longer working at the start of the sampling. The LEDs are powered by the MOCNESS battery and their pulse width, amplitude, flash rate period, and on/off are controlled by the MOCNESS software. For this cruise the pulse width was 2 ms, the relative amplitude was 99%, and the flash interval was 100 ms.

| MOCNESS-CTD Data from Guaymas Basin vent region, AII-112-28, 1985 from R/V Atlantis II AII-112-28, July 1985 | This system was equipped with 9 1-m^2 nets of 333 µm nitex nylon mesh, which presented a 1-m^2 mouth opening when towed with the frame at 45 degrees from the vertical. The system carried Sea Bird temperature and salinity probes, a down welling light sensor, a bottom finding 12 kHz pinger, a pressure transducer, a modified TSK flowmeter, and an angle inclinometer. Data from the sensors were transmitted up to a deck unit via conducting cable where they were displayed and saved on 1/4" cassette tape. Data were also passed from the deck unit to a CBM microcomputer for real time processing, storage on floppy disc, printing, and plotting.

The MOCNESS-1 has nine rectangular nets (1m x 1.4 m) which are opened and closed seq uentially by commands through conducting cable from the surface (Wiebe et al., 1976). In MOCNESS systems, "the underwater unit sends a data frame, comprised of temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds... Temperatu re (to approximately 0.01 deg C) and conductivity are measured with SEABIRD sensors . Normally, a modified T.S.K.-flowmeter is used... Both the temperature and conductivity sensors and the flowmeter are mounted on top of the frame so that they face horizontally when the frame is at a towing angle of 45deg... Calculations of salinity (to approximately 0.01 o/oo S), potential temperature (theta), potential density (sigma), the oblique and vertical velocities of the net, and the approximate volume filtered by each net are made after each string of data has been received by the computer."

| ZooSCAN images of zooplankton collected with MOCNESS tows during six R/V Atlantic Explorer cruises in the northwest Atlantic (Sargasso Sea) from 2021 to 2023 | The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton. Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974)(from MOCNESS manual). The MOCNESS used in this experiment is a 1m2 (mouth size) rigged with nine 150um mesh nets. One is flown open on the downcast to balance the net (Net 0- contents preserved but not analyzed), and the other eight (Net 1-8) are triggered on the upcast at desired depths. This particular MOCNESS was originally manufactured by Biological Environmental Sensor Systems (BESS), but was refit with new electronics from SIO/STS in 2017 (Net Interface Unit, Net Angle Sensor) to allow it to interface with Seabird instruments (SBE9Plus CTD, SBE3S Temperature, SBE4C Conductivity, SBE11 Deck Box).
