©2020 Biological and Chemical Oceanography Data Management Office.A Reeve Net is a conventional ring net with a very large acrylic cylindrical cod-end (30 liters) designed to collect fragile gelatinous animals. The net is lowered to a particular depth and then hauled slowly back to the surface (5-10 m/min). Reeve (1981) also described a double net system with no bridle and flotation at the net mouth that is attached to a roller mechanism that rides on a tow wire.
The roller system is locked in place by a pressure release device. Once below a set pressure, the roller
and nets are released and they float slowly up the wire, gently collecting the zooplankton, without being
influenced by the motion of the vessel and associated vertical wire movements. (from Wiebe and Benfield, 2003)

| Organismal physiological metrics from time series experiments on samples collected on R/V Atlantic Explorer cruise AE1910 in May 2019 | Nighttime tows (early- and mid-night) were conducted using a 1-m² Reeve net deployed to 200 m depth, with 150 µm mesh size, 20 L cod end, and a miniSTAR-ODDI pressure and depth sensor. | Reeve net |
| BIOS-SCOPE survey biogeochemical data as collected on Atlantic Explorer cruises (AE1614, AE1712, AE1819, AE1916) from 2016 through 2019 | During the winter and the summer cruises a Reeve net (1 m mouth, 150 µm mesh) will be towed obliquely from 150 m to the surface at the start of each evening when the echo-sounder indicates that the DVM zooplankton have returned to the surface, and late evening (~ 4 am) prior to the descent of the DVM layer. | Reeve net |

| Routine metabolic rate (RMR) and critical partial pressure (Pcrit) measurements of Salpa fusiformis collected aboard R/V Atlantic Explorer cruise AE2306 in the Sargasso Sea in March 2023 | A circular Reeve net with 150 micron mesh with a 20 L cod end was used for collections. The Reeve net was manufactured by SeaGear, Melbourne FL, USA | SeaGear Reeve net |

| O2 consumption of pteropods held for 1-14 days in three CO2 treatments with pteropods collected with a Reeve net during R/V Tioga cruises in the Gulf of Maine from 2013 to 2014 | Reeve net with 333-m mesh and a large cod end | |
| Shell quality of pteropods held for 1-14 days in three CO2 treatments with pteropods collected with a Reeve net during R/V Tioga cruises in the Gulf of Maine from 2014 to 2015 | Reeve net with 333-m mesh and a large cod end | |
| Event log for R/V Tioga TI725 in the Gulf of Maine from January 2014 (Gulf of Maine Pteropods project) | 150 micron mesh. The objective of Reeve net sampling was to gently collect live specimens to be sampled for culturing experiments. These trawls were short in duration and aimed to maximize pteropod catch. | Reeve Net |
| Event log for R/V Tioga TI729 in the Gulf of Maine from January 2014 (Gulf of Maine Pteropods project) | A 1-m diameter Reeve net with a 150-um mesh net was deployed via the A-frame. The book-clamp to attach the net was borrowed from Carin Asjian’s lab. Ship speed during tows was ~1-1.5 knots. The depth and duratilon of deployment varied widely. We occasionally focused on very deep (90-130) or very shallow (40-20) layers based on acoustic evidence, but had our greatest success with a tow-yo pattern that focused on depth ranges between 40-90 m (See Cruise Report, Table 1 and Appendix 4 for details). http://bcodata.whoi.edu/GoME_Pteropods/cruise_reports/Tioga729_Cruise_Report.pdf | Reeve Net |
