attribute NC_GLOBAL acquisition_description String The NBST carried 4 collection tubes with a diameter of 12 cm (Valdes and Price\n2000). The STST included 5 frames (KC Denmark) clipped onto a surface-\ntethered, free drifting array line at increasing depths and each frame carried\n4, 7 cm diameter collection tubes. The WW trap consisted of one, 4-tube trap\nframe (KC Denmark) tethered by a bungee below the profiling component of the\nWW array.\\u00a0 To prepare tubes for deployment, seawater was collected from a\ndepth of 150 m using a CTD rosette and pumped through a 1 \\u03bcm filter\ncartridge. Trap tubes were filled with filtered water overlying a jar\ncontaining a polyacrylamide gel layer (Durkin et al. 2015). Trap platforms\nwere deployed for between 1 day and 3.5 days (see Trap Deployment Log).\\u00a0\nIdentically prepared tubes were incubated in parallel onboard the ship to\nserve as process blanks.\n \nUpon recovery, collection tubes were allowed to settle for at least 1 hour\nbefore the overlying water was siphoned off.\\u00a0 Jars containing\npolyacrylamide gel were removed from trap tubes and the remaining overlying\nwater was carefully pipetted off the gel.\\u00a0 Gels were stored at 4 degrees\nC and imaged within the following 2 days before being stored at -80 degrees\nC.\\u00a0\n \nPolyacrylamide gel layers were imaged on a dissecting microscope (Olympus\nSZX16) with either a Luminera Infinity 2 (FK170124) or an Allied Vision\nTechnologies StingRay (EN572 and EN581) camera attachment.\\u00a0 Particles\ncollected in gel layers during EN572 and EN581 were imaged under brightfield\nillumination.\\u00a0 Particles collected in gel layers during FK170124 were\nimaged under both brightfield and oblique illumination, producing two separate\nsets of images for each sample.\\u00a0 EN572 gel layers were imaged with a\ntransparent grid to assist in tracking gel location during imaging. The grid\nwas not used when imaging samples collected during subsequent cruises because\nthe pronounced grid lines complicated image analysis. All gel layers were\nimaged at 4 increasing magnifications, though the combination of\nmagnifications varied by cruise: at 7x, 20x, 40x, and 115x for EN572 samples,\nat 7x, 20x, 40x, and 80x for EN581 samples, and at 7x, 20x, 50x, and 115x for\nFK170124 samples. At magnifications greater than 7x, multiple focal planes\nwithin a field of view were imaged to capture particles embedded in different\ndepths of the gel layer.\\u00a0 The number of focal planes imaged was\nconsistent across all fields of view for a given magnification but varied\nacross cruises due to variation in gel thickness and particle types present.\nTo determine whether measured particle properties changed if gel layers are\nfrozen, samples collected during FK170124 were thawed after being stored for\napproximately 1 year at -80\\u00a0 degrees C and imaged again under both\nbrightfield and oblique illumination.

attribute NC_GLOBAL projects_0_description String Text from the NSF award abstract:\nCarbon is fixed into organic matter by phytoplankton growing in the surface ocean, and is naturally sequestered in the ocean interior when particles and organisms sink: a process called the \"biological pump.\" Because of its recognized influence on the global carbon cycle, ocean scientists have studied the biological pump for decades. However, we still do not have a sufficient understanding of the underlying processes to accurately quantify and predict carbon cycling. Much of this uncertainty stems from an inability to directly link specific plankton in the surface ocean with the types of particles sinking out of the surface ocean. To address this missing link in biological pump research, this work will directly observe how plankton are transported out of the surface ocean using novel, particle-specific observational approaches embedded within an interdisciplinary field program that will finely resolve upper ocean plankton groups and the resulting amount of sinking carbon across space and in time. The genetic identity of organisms within different types of sinking particles will be determined by sequencing the genetic contents of individually collected particles. This new application of a molecular method will definitively link surface plankton with sinking particles at five locations across the Pacific Ocean. This work has the potential to transform our understanding of the biological pump by identifying previously unknown links between surface ecosystems and sinking carbon particles. Because this work is embedded within an interdisciplinary field program, including biogeochemical modelers and remote sensing scientists, these data will feed directly into new models of the biological pump, improving our ability to quantify and predict carbon uptake by the ocean. This project will train 1 graduate student and at least 2 undergraduate researchers. Findings will be communicated to the non-scientific public through blogs, videos, and the public communication channels of participating institutions.\nAccurate prediction of the global carbon cycle requires an understanding of the specific processes that link surface plankton communities and sinking particulate carbon flux (export) out of the surface ocean, but current methodological paradigms in biological pump research do not directly observe these processes. This project will comprehensively determine who is exported from the surface ocean and how using new, particle-resolving optical and molecular techniques embedded within a sampling scheme that characterizes export events at high time and space resolution. The investigation suggests that different plankton types in the surface waters are transported out of the surface ocean by distinct export pathways, and that an understanding of these connections is critical knowledge for global carbon cycle modeling. If successful, this work has the potential to transform our conceptual understanding of the biological pump by directly identifying mechanisms that link surface plankton with particle export, without relying on bulk sampling schemes and large-scale correlation analysis. Particle export environments will be studied at five open ocean locations during a cruise from Hawaii to Seattle in January-February 2017. The surface plankton communities will be characterized by a combination of satellite observations, sensors attached to a free-drifting, continuously profiling WireWalker, an in situ holographic camera, microscopy, and by sequencing 18S and 16S rRNA gene fragments. Exported particles will simultaneously be captured by various specialized sediment traps and their characteristics will be directly related to their sources in the surface community by identifying the genetic contents of individual particle types. Individual particles will be isolated from gel layers and the 16S and 18S rRNA gene fragments will be amplified and sequenced. This work would, for the first time, combine molecular approaches with particle-specific observations to enable simultaneous identification of both which organisms are exported and the processes responsible for their export.
