©2026 Biological and Chemical Oceanography Data Management Office.The SBE 32 is a Carousel Water Sampler. With an accessory Deck Unit, the Carousel provides water sampling and real-time CTD data acquisition with any Sea-Bird profiling CTD (requires electro-mechanical cable and slip-ring equipped winch). With an accessory underwater unit, the Carousel can operate autonomously with a Sea-Bird Scientific profiling CTD and can be programmed to close bottles at selected depths, allowing deployment using non-electrical wire or line. The Carousel is available in two models: • Full-size SBE 32 for a 12 or 24-position system (36-position custom). • Compact SBE 32C for a 12-position sampler with bottles up to 8 liters, for use with limited vertical clearance.
| Dataset Name | Submitter Supplied Description | Submitter Supplied Name |
|---|---|---|
| CTD data and particulate organic carbon, particulate organic nitrogen, and adenosine triphosphate from Niskin bottle samples collected along the coastal ocean off Virginia Beach into the Chesapeake Bay aboard RV Fay Slover on April 1, 2024 | Conductivity, temperature, and depth were measured using a Seabird SBE 32 CTD equipped with a Wetlabs fluorometer and a Wetlabs transmissometer (650 nm). | Seabird SBE32 CTD rosette |
| Niskin bottle metadata and environmental measurements associated with bacterial DNA samples collected from January to February 2022 during RVIB Nathaniel B. Palmer cruise NBP 22-02 in the Amundsen Sea Embayment | Hydrographic variables were measured with the use of a CTD/rosette system. The conventional (CNV) package included a Seabird 911+ system on a 24-bottle SBE32 rosette. | SBE32 rosette |
| Iodine speciation depth profile measurements from the Gotland Deep and Fårö Deep, Baltic Sea, collected aboard R/V Elisabeth Mann Borgese cruise EMB276 in Sep 2021 | Seawater depth profiles for iodine analyses was collected onboard through HYDRO-BIOS free flow water samplers on a SBE32 water sampler which were mounted on a CTD rosette (conductivity-temperature-depth profiler). | SBE32 water sampler |
| Iron uptake rates from Hawaii Ocean Time-series (HOT) cruises on R/V Kilo Moana at Station ALOHA in the North Pacific Subtropical Gyre from May 2021 to September 2023 | SBE32C | |
| Dissolved iron-binding ligand concentrations and conditional stability constants from field samples collected on US GEOTRACES GP17-ANT cruise NBP24-01 on RVIB Palmer in the Amundsen Sea from Nov 2023 to Jan 2024 | Depth profile samples have been collected with the GEOTRACES Trace Element Carousel sampling system (GTC) that includes an A-frame, a Seabird SBE 32 carousel/CTD equipped with 24 Go-Flo bottles (General Oceanics) of 12 L, a Dynacon winch with 7300 m of Vectran cable with conductors, and clean lab van for bottle sub-sampling (Cutter and Bruland, 2012). | Seabird SBE 32 carousel/CTD |
| Seabird SBE 32 trace metal-modified frame and rosette sampling system was used for depth profile sample collection. | Seabird SBE 32 | |
| Dissolved iron-bound and total Fe-binding humic-like substances for water column samples collected in the West Antarctic Peninsula region of the Southern Ocean on RVIB Nathaniel B. Palmer cruise NBP1608 in Sept-Oct 2016 | Used for depth profile sample collection | Seabird SBE 32 trace metal-modified frame and rosette sampling system |
