attribute NC_GLOBAL acquisition_description String Methodology:\n \nSamples were collected during two deployment cycles (termed deployment 1 and\ndeployment 2) occupied during the RRS Discovery cruise DY077 to the Porcupine\nAbyssal Plain Sustained Observatory (PAP-SO) Site in April 2017 (Figure 1). In\neach of the cycles, we conducted particle flux sampling method\nintercomparisons between two types of neutrally buoyant sediment traps (NBST\nand PELAGRA), a surface tethered array of sediment traps (STT), and fluxes\nderived from upper water column deficits of 234Th vs. its parent isotope,\n238U. DY077 samples analyzed in US (WHOI and Skidmore College) are archived\nhere; DY077 samples analyzed in the UK (NOC) are archived in the British\nOceanographic Data Centre.\n \nNeutrally Buoyant Sediment Trap (NBST)  \n NBSTs consist of four cylindrical sediment trap tubes (collection area\n0.0113 m2) and a 0.25-m pathlength transmissometer (C-Rover 2000, WETLabs,\nInc.) arranged around a central SOLO profiling float. The traps are programmed\nto sink to a predetermined depth, drift while collecting sedimenting\nparticles, close the trap lids, and then rise to the surface at a programmed\ntime for recovery. Recovery aids consist of GPS/Iridium and a flashing strobe\nlight. The transmissometer operates as an optical sediment trap and measures\nattenuance flux as a function of time, which is a proxy for sinking\nparticulate carbon flux. For the deployments conducted on DY077, trap tubes\nwere set up as follows: Three tubes were prepared with a layer of 500 mL of 70\nppt brine poisoned with 0.1% formaldehyde and borate buffered to pH 8.5. This\nbrine layer was overlain with 1-\\u03bcm filtered seawater from 350 m. In the\nfourth trap tube, a jar containing approximately 50 mL of polyacrylamide gel\nreplaced the brine layer and allowed preservation of collected particles for\nmicroscopic imaging after recovery. During deployment 1, the NBST sampled at a\ndepth of 200 m; during deployment 2, it sampled at a depth of 350 m.\n \nPELAGRA neutral sediment traps  \n The Particle Export LAGRAngian (PELAGRA) trap was designed at the National\nOceanography Centre, Southampton, UK (Lampitt et al. 2008) and consists of an\narrangement of four conical traps (collection area 0.5 m2) around an APEX\nfloat (Teledyne-Webb Research, Inc.), with mechanically opening and closing\ncollection cups. For this cruise, samples were collected from three PELAGRA\ntraps: P4, P7, and P9. P4 and P7 each carried two conventional sediment\nfunnels, two non-funnelled collectors for gel sampling and a camera/flash\nsystem for capturing time-lapse images of sinking particles. For these traps,\nthe two cups situated beneath the conventional funnels were filled with the\nsame brine solution used in the bottom of the NBST traps. Under the non-funnel\ncollectors, jars containing polyacrylamide gel (described above) and\ncommercially available cryogel were attached. P9 carried four conventional\nsediment funnels, each with a brine cup installed.\n \nSurface Tethered Trap (STT) arrays  \n Alongside the neutral traps was deployed a drifting mooring carrying\ncylindrical sediment trap tubes set up identically to those on the NBSTs as\nwell as tubes of a different design provided by collaborator C. Lamborg (and\nhenceforth termed modified PIT tubes). Modified PIT tubes are identical to\nstandard PIT tubes (collection area 0.00385 m2) but with detachable bottoms.\nDuring deployment 1 two arrays were deployed, one at 200 m and one at 350 m.\nBoth arrays contained two NBST-style brine-filled tubes, one NBST-style gel\ntube, and two modified PIT tubes which collected samples into 125-mL bottles\nfilled with the same poisoned brine used in the other tubes. A programmable\nburnwire controller was set up to close the NBST-style tube lids at the same\ntime as on the NBST traps. The burnwire controller at 200 m operated as\nplanned but the controller at 350 m did not, due to a hardware failure. During\nthe second deployment, a single trap array at 350 m was deployed using the\nfully-functioning burnwire controller. Two NBST-style tubes were set up to\nclose at the same time as the NBSTs, two more were set up to remain open, and\na third pair of modified PIT tubes (without lids) were included. During both\ndeployments a Nortek current meter was deployed looking downwards\napproximately 2 m below the bottom of the 350-m trap array\n \nUpon platform retrieval, trap brine samples were processed as follows.  \n NBST samples and NBST-style tubes on STT: After a period of 1-3 hours to\nallow particles to finish settling in trap tubes, overlying filtered seawater\nwas removed via peristaltic pump. The bottom brine layer was screened through\n350-\\u03bcm nylon mesh to aid in swimmer removal. The replicate brine tubes\nwere drained through a single screen and combined. The screen was picked under\n12x magnification to remove obvious swimmers while leaving behind passively\nsinking particles. Material remaining on the screen was rinsed back into the\nmain sample while swimmers were filtered onto a QMA filter for later carbon\nand thorium-234 analysis. Combined trap samples were split eight ways using a\ncustom rotary splitter. Splits were filtered onto QMA filters for C/N, PIC,\nand 234Th analysis or polycarbonate filters for biogenic Si and mass analysis\non shore. Splits were also kept aside to return to collaborators labs at NOC.\n \nModified PIT tubes on STT: Overlying seawater was siphoned off as above, then\nthe 125-ml sample collection bottles were removed and combined into an extra\nNBST tube used as a dispenser. The sample was processed from this point\nidentically to the NBST tubes.  \n PELAGRA trap samples: Brine cups were removed and either kept by the NOC lab\nfor parallel processing (generally cup 1 on P4 and P7 and cups 3 and 4 on P9)\nor treated as described for modified PIT tubes above, minus the siphoning\nstep.\n \nQMA filters were dried at 45C, mounted, and immediately counted for low-level\n\\u03b2 emission onboard the ship. At WHOI, a subset of samples was re-counted\nwithin one month on shore. Final background counts to measure non-234Th\nrelated \\u03b2 emissions were conducted several months later. At this point,\nQMA filters were unmounted, re-dried, and gravimetrically subdivided into four\nsections. One half of the filter was analyzed for total carbon and nitrogen\nafter high-temperature combustion on a Thermo Electron FlashEA 1112 C/N\nanalyzer. Coulometric analysis for PIC after sample acidification was\nperformed on a quarter of the filter (Johnson et al, 1985; Honjo et al, 2000).\nThe remainder of the filter was archived. At Skidmore College, polycarbonate\nfilters for mass and bSi determination were dried and weighed repeatedly on a\nmicrobalance until stable weights with a precision better than 0.01 mg were\nachieved. Filter tare weights were subtracted and net mass accumulation was\ncalculated. Then the filters were digested to release bSi using a weak\nalkaline digest (0.2 N NaOH for 2 hours at 95C) and analyzed following\nstandard spectrophotometric methods (Strickland and Parsons, 1972).\n \nA replicate set of each type of trap collector was prepared as described\nabove, held in the shipboard laboratory during each deployment, and then\nanalyzed in parallel to provide a process blank determination. The blanks from\nthe two deployments were averaged to determine the mean process blank for the\ncruise (Table 1).

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nThere is considerable need to understand the biological and ecological processes that through net primary production fix dissolved carbon dioxide (CO2) into organic matter in the upper ocean, and the processes that subsequently transport this organic carbon in to the ocean's interior. Most of the particulate organic carbon flux to the deep ocean is thought to be mediated by sinking particles. Ultimately it is the deep organic carbon transport and its sequestration that define the impact of ocean biota on atmospheric CO2 levels and hence climate. Currently, various methods are available to measure the amount of particles in the ocean that sink over a specified period of time commonly referred to as particle flux. Unfortunately, all of these methods are used independently of each other with very little intercomparison, leaving some uncertainty as to which approach provides the most accurate estimates. This study seeks to be the first concerted effort to standardize particle flux measurements. Seeking to keep the cost modest, the researchers are taking advantage of a collaboration with scientists in the United Kingdom to participate in an already scheduled research cruise. The proposed research will have much greater impact that merely standardization of particle flux measurements because it will provide the science and modeling community the ability to quantify the transfer of carbon throughout the surface ocean. Also, this project provides a variety of mentoring and training opportunities for students. A PhD student at Woods Hole Oceanographic Institute will get their first sea-going experience and will learn all of the processing steps for the study of an isotope of thorium (234Th). Skidmore College will have an undergraduate participant in the research and the results from the cruise will also be an excellent additional component for undergraduate oceanography classes.\nResearchers from Woods Hole Oceanographic Institution and Skidmore College, in collaboration with a scientist from the National Oceanography Centre, Southampton will inter-compare direct, tracer, and optical-sensor methods used to determine sinking particle fluxes in the surface ocean. To do this, they will firstly conduct a comparison of two types of neutrally buoyant traps and one surface-tethered, drifting array. Secondly, measured trap fluxes will be compared to predicted 234Th fluxes from a 3D time-series of data. Lastly, optical sediment trap measurements will be compared to particle size distributions in the water column and gel traps, as well as size-fractionated particles on filters from large volume pumps. With this research, global ocean models, particularly carbon, will have greater accuracy and stronger conclusions will be able to be drawn from them.
