| All the species seen during broad-scale cruises from the US-GLOBEC Georges Bank Program | MOCNESS 1/4 meter square nets. | MOCNESS.25 |
| Concentration of anchovies from hypoxic waters of the Chesapeake Bay collected by R/V Hugh R. Sharp (HRS100524JP, HRS100819JP, HRS100920JP, HRS110525JP, HRS110719JP, HRS110922JP) from 2010-2011 (DeZoZoo project) | Had trouble communicating with the 1/4 m2 MOCNESS in the beginning of the first cruise. Picked up replacement parts and were able to get it working again with an underwater unit borrowed from BESS, the manufacturer of the MOCNESS system. (Subsequent analysis by BESS, Inc. showed that some damage to the underwater unit was caused when it was plugged into the sea cable with some charge still in the cable -- most likely from the Seabird deck unit still turned on.) -- from the Cruise Report | 1/4 Meter MOC |
| 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) | Mesozooplankton (> 64 µm) were collected from tows with a 0.25 m^2-mouth area MOCNESS equipped with nine nets with a 7:1, mouth:length ratio (Wiebe et al., 1985). | Baby MOC, MOC-1/4 |
| CTD data from the 0.25m2 MOCNESS tows, including ancillary tow information, from NOAA Ship Ronald H. Brown cruise RHB0603 in the Sargasso Sea and Southeast North Atlantic Ocean in 2006 (CMarZ_2004-2010 project) | The MOCNESS is based on the Tucker Trawl principle (Tucker, 1951). The particular MOCNESS system from which these CTD data came is one of three net systems. The MOCNESS-.25 carries nine rectangular nets (1/4-m2), usually with 64 micrometer mesh. | MOCNESS.25 |

| Event log for R/V Tioga TI729 in the Gulf of Maine from January 2014 (Gulf of Maine Pteropods project) | The MOCNESS-1/4 was equipped with nine 150-um mesh nets (nets 0-8). The underwater unit used was #169; temperature probe was #535 and conductivity probe was #120. 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. 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. | MOC.25 |
| Event log from R/V Tioga TI746 in the Gulf of Maine from April 2014 (Gulf of Maine Pteropods project) | The MOCNESS-1/4 was equipped with nine 150-um mesh nets (nets 0-8). The underwater unit used was #169; temperature probe was #535 and conductivity probe was #120. 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.

| Event log from R/V Tioga TI777 in the Provincetown to Gulf of Maine from August 2014 (Gulf of Maine Pteropods project) | The MOCNESS-1/4 was equipped with nine 150-um mesh nets (nets 0-8). The underwater unit used was #169; temperature probe was #535 and conductivity probe was #120. 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.

| Event log from the R/V Tioga (TI787) in the Gulf of Maine during November 2014 (Gulf of Maine Pteropods project) | The MOCNESS-1/4 was equipped with nine 150-um mesh nets (nets 0-8). The underwater unit used was #169; temperature probe was #535 and conductivity probe was #120. 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.

| MOCNESS tow log sheets from Gulf of Maine Tioga cruises, 2013 from R/V Tioga cruises in the Wilkinson Basin, Gulf of Maine from 2013-2014 (Gulf of Maine Pteropods project, GoME OA Pteropods project) | The MOCNESS was equipped with nine 150-um mesh nets (nets 0-8). The underwater unit used was #169; temperature probe was #535 and conductivity probe was #120. A connector cable converting from the 4-pin Seacon connector at the wet end of the 0.322" EM cable on the Tioga's winch to the 2-pin EO connector required by the MOCNESS was required. Both the MOCNESS and CTD required the same pins and so the dry end connectors needed to be swapped out between operations. To simplify this change over, for this cruise, Captain Ken Houtler had a new connector made for the wheelhouse, connecting the ground and first pin wires in the wheelhouse junction box to a BNC connector. The MOC or CTD deck units were then connected to this BNC. 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. 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. The 5A fuse in the underwater unit that connects to the strobe blew on the first net cast and the canister was subsequently disconnected from the system. | MOC.25 |

| Trichodesmium species in the North Atlantic from R/V Oceanus OC471-01 in the NW Atlantic: Woods Hole to Barbados from April 2011 (Trichodesmium project) | MOCNESS-1/4 nets had 150 micron mesh. | MOC.25 |
