attribute NC_GLOBAL acquisition_description String Water samples were collected from CTD Niskin bottles. Water samples for HPLC\nanalyses were taken from one Niskin bottle per cast-depth combination included\nin the dataset. Note that the niskin_sampled column indicates which Niskin\nbottle the HPLC sample was taken from. The niskins_fired column indicates all\nNiskin bottle numbers fired at the specified depth, though the HPLC sample was\ntaken from only one of those bottles.\n \nChlorophyll and accessory pigment composition was analyzed by high performance\nliquid chromatography (HPLC; Agilent 1100). Culture aliquots were filtered on\nWhatmann GF/F filters, flash frozen in liquid nitrogen, and stored at\n-80\\u00b0C until analysis. Just prior to analysis, pigments were extracted\novernight in acetone at -20\\u00b0C. The following day extracted pigments were\ncentrifuged and measured using a gradient elution method (DiTullio and Geesey,\n2003), a modification of the Zapata et al 2000 method. Chromatographic\nseparation was performed using a Waters C8 symmetry column, photodiode array\nand fluorescence detectors. The internal standard, \\u03b2-Apo-8-carotenal-\ntrans standard (Fluka Chemical Corp., USA) was added to extracted pigments as\na peak reference. Individual pigment peaks were quantified with Chemstation\nsoftware (revision B.03.01, Agilent) and our pigment action spectra library\ncalibrated using pigment standards from DHI LABS (Hoersholm, Denmark) and in-\nhouse purifications of non-commercially available pigments. Coefficient of\nvariation among replicate HPLC injections is < 3% and our limit of detection\nis approximately 1 ng L-1.

attribute NC_GLOBAL instruments_1_description String A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

attribute NC_GLOBAL projects_0_description String This project is also called \"NA-VICE\" (North Atlantic Virus Infection of Coccolithophores Expedition).\nProject description from NSF award abstract:\nDespite the critical importance of viruses in shaping marine microbial ecosystems, very little is known about the molecular mechanisms mediating phytoplankton-virus interactions. As a consequence, we currently lack biomarkers to quantify active viral infection in the oceans, significantly hindering our understanding of its ecological and biogeochemical impacts.\nThe coccolithophore Emiliania huxleyi (Prymnesiophyceae, Haptophyte) is a cosmopolitan unicellular photoautotroph whose calcite skeletons account for about a third of the total marine CaCO3 production. E. huxleyi forms massive annual spring blooms in the North Atlantic that are infected and terminated by lytic, giant double-stranded DNA containing coccolithoviruses. Findings that lytic viral infection of E. huxleyi recruits the hosts programmed cell death (PCD) machinery demonstrate that viruses employ a sophisticated, co-evolutionary “arms race” in mediating host-virus interactions. The investigators recently demonstrated that viral glycosphingolipids (vGSLs), derived from unexpected cluster of sphingolipid biosynthetic genes, a pathway never before described in a viral genome, play a crucial functional role in facilitating infection of E. huxleyi. The observations of vGSLs in the North Atlantic and Norwegian fjords further suggest that they may be novel, diagnostic biomarkers for viral infection of coccolithophore populations. At the same time, the discovery of vGSLs and a distinct, protective 802 lipid argues that a host-virus, co-evolutionary chemical arms race plays a pivotal role in regulating viral infection and in lubricating upper ocean biogeochemical fluxes of carbon and sulfur.\nThe focus of this collaborative research project is to elucidate the molecular, ecological, and biogeochemical links between vGSLs (and other polar lipids) and the global cycles of carbon and sulfur.\nThe team of investigators proposes a multi-pronged approach combing a suite of lab-based, mechanistic studies using several haptophyte-virus model systems along with observational studies and manipulative field-based experiments the Northeast Atlantic. Using these diagnostic markers, they will document active viral infection of natural coccolithophore populations and couple it with a suite of oceanographic measurements in order to quantify how viral infection (via vGSLs) influences cell fate, the dissolved organic carbon (DOC) pool, vertical export of particular organic (POC) and inorganic carbon (PIC; as calcium carbonate, CaCO3) (along with associated alkenone lipid biomarkers and genetic signatures of viruses and their hosts) and the upper ocean sulfur cycle (via the cycling of dimethylsulfide [DMS] and other biogenic sulfur compounds). Furthermore, given they are unique to viruses, the investigators propose that vGSLs can be used to trace the flow of virally-derived carbon and provide quantitative insights into a “viral shunt” that diverts fixed carbon from higher trophic levels and the deep sea.\nThe overarching hypothesis for this study is that vGSLs are cornerstone molecules in the upper ocean, which facilitate viral infection on massive scales and thereby mechanistically \"lubricate\" the biogeochemical fluxes of C and S in the ocean.
