attribute NC_GLOBAL acquisition_description String Water was collected from a circulating seawater system distributed via plastic\ntubing for POC/PON/POP around 3m deep. An underway system was chosen to vastly\nincrease sampling coverage, replicate number, and sample volume. The water\nintake is located near the ship sea chest, which may have missed particle\nproduction in the subsurface. The circulating seawater was never turned off\nduring the entirety of the transect and kept at a constant flow. Water was\npassed through a 30\\u03bcm nylon mesh (Small Parts #7050-1220-000-12) to\nremove larger plankton and particles from the sample. Each replicate was\ncollected into a separate 8.5L plastic carboys (Thermo Scientific, Waltham,\nMassachusetts). In between stations, carboys were rinsed with 30 \\u03bcm\nfiltered sample water just prior to collection. Six 8 L seawater samples were\ndivided into POC/PON and POP triplicates. Carboys were placed at ~45\\u00b0\nangle to avoid particle settling below the nozzle. Each replicate was passed\nthrough a 25 mm pre-combusted (500\\u00b0C for 5 h) GF/F filter (Whatman,\nFlorham Park, New Jersey) with a nominal pore size of 0.7 \\u03bcm. The vacuum\nfiltration was an in-line setup with 25 mm filter holders connected to an\naspirator pump at -0.08 MPa. POP filters were rinsed with 5 ml of 0.17 M\nNa2SO4 to remove traces of dissolved phosphorus from the filter. All filters\nwere stored in pre-combusted aluminum packets and immediately frozen at\n-80\\u00b0C during the cruise and -20\\u00b0C for shipment.\n \nParticulate Organic Carbon/Nitrogen: Prior to analysis, the filters for POC\nand PON were dried according to the JGOFS protocol1. The protocol has a\ndetection range of 0.43-43.13 \\u00b5M for POC and 0.037-7.39\\u00b5M for PON in\nsea water1. First, the filters were dried in an incubator at 55\\u00b0C for\n24-48 h and then stored in a desiccator with concentrated HCl fumes for 24 h\nto remove inorganic carbonates. Secondly, the filters were dried again at\n55\\u00b0C for 48 h before being folded and packed into pre-combusted tin\ncapsules (CE Elantech, Lakewood, New Jersey). The packaged filters are\nanalyzed on a CN FlashEA 1112 Elemental Analyzer (Thermo Scientific, Waltham,\nMassachusetts) against an atropine standard curve (chemical formula\nC17H23NO3).\n \nParticulate Organic Phosphorus: Particulate organic phosphorus (POP) were\nanalyzed according to a modified ash-hydrolysis protocol2. Thawed filters were\nplaced in along with a corresponding standard curve of KH2PO4. 2 mL of 0.017M\nMgSO4 was added to the acid-washed glass vials containing filters and covered\nwith pre-combusted aluminum foil. The vials were placed in an incubator at\n90\\u00b0C for 24 h and then combusted (500\\u00b0C, 2 h). Once cooled, 5 mL 0.2\nM HCl was added and incubated at 90\\u00b0C for at least 30 min. Next, the\nsupernatant plus 5 mL milli-Q water was mixed with 2:5:1:2 parts ammonium\nmolybdate tetrahydrate, 5N sulfuric acid, potassium antimonyl tartrate, and\nascorbic acid for 30 min. Finally the standards and samples were analyzed on a\nspectrophotometer (Genesys 10vis, Thermo Scientific, Waltham, Massachusetts)\nat a wavelength of 885 nm to determine POP concentration with an assay\ndetection limit ~0.1 nmol l-1.

attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nThe Indian Ocean accounts for nearly a fifth of global ocean photosynthesis and is likely a key component in global ocean nutrient and carbon cycles. However, the Indian Ocean may be the least studied major marine body on the planet. Our limited understanding suggests extensive variations in physical and chemical environmental conditions, but how this variation influences biodiversity, nutrient stress, and more broadly regional differences in the functioning of phytoplankton is unknown. To help address these gaps, the investigators will conduct a study by joining an already-funded major research cruise to this region. It will cover a northern region with some of the highest temperatures recorded in open ocean waters, an area around 10°S of predicted (but not tested in situ) iron stress, and a southern subtropical gyre with unique nitrogen to phosphorous(or N:P) ratios. The focus of this project is to quantify and synthesize the interconnectedness of environmental conditions, phytoplankton diversity and genome content, and nutrient biogeochemistry, with the goal of understanding how these may lead to unique biogeochemical regions in Indian Ocean. The research will have broader impacts on many levels. First, it will increase public awareness of the role of phytoplankton on ocean functioning, climate, and people's lives through a new partnership with the Aquarium of the Pacific (AOP), which is the fourth most-attended aquarium in the nation. Secondly, the project will train a postdoctoral scholar as well as a graduate and undergraduate students. Third, the research will dramatically increase our basic knowledge ocean biogeochemistry and in many cases will be the first measurements of their kind made in the Indian Ocean.\nThis project will address two major questions: How do environmental conditions, phytoplankton diversity, phytoplankton physiology, and biogeochemistry vary across the central Indian Ocean? Are there distinct biogeochemical regimes in the central IO? The researchers hypothesize that environmental conditions, including the relative availability of nitrogen (N) and iron (Fe), lead to three distinct phytoplankton communities and biogeochemical regimes. They will employ a series of advanced analytical tools including high sensitivity measurements of dissolved and particulate nutrients (nitrogen, phosphorus, and iron), genomics, bioassays to test for nutrient stress, and cell-sorting of specific taxa followed by measures of nutrient content and uptake. A focus of this project is to quantify and synthesize the interconnectedness of environmental conditions, phytoplankton diversity and genome content, and nutrient biogeochemistry, and how these lead to unique biogeochemical regions in Indian Ocean. This extensive set of observations can ultimately be linked to ocean models and satellite data to provide a comprehensive view of regional differences in chemistry, biodiversity and phytoplankton biogeochemical functioning in the Indian Ocean.
