These data were primarily collected opportunistically during the course of water collection for incubation experiments (see separate dataset for incubations), and provide field context for the shipboard incubation experiments as well as temporal characterization of a retentive anticyclonic eddy occupied over the course of the cruise.\n\nThis research focuses on the vertical export of the carbon associated with a major group of phytoplankton, the diatoms in the North Atlantic near the Porcupine Abyssal Plain. The major objective is to understand how diatom community composition and the prevailing nutrient conditions create taxonomic differences in metabolic state that combine to direct diatom taxa to different carbon export pathways. The focus is on diatoms, given their large contribution to global marine primary productivity and carbon export which translates into a significant contribution to the biogeochemical cycling of carbon (C), nitrogen (N), phosphorus (P), iron (Fe) and silicon (Si). It is hypothesized that the type and degree of diatom physiological stress are vital aspects of ecosystem state that drive export. To test this hypothesis, combined investigator expertise in phytoplankton physiology, genomics, and trace element chemistry is used to assess the rates of nutrient use and the genetic composition and response of diatom communities, with measurements of silicon and iron stress to evaluate stress as a predictor of the path of diatom carbon export. The EXPORTS field campaign in the North Atlantic sampled a retentive eddy over nearly a month in May 2021, which coincided with the decline of the North Atlantic Spring Bloom.\n\ncdm_data_type = Other\nVARIABLES:\nCRUISE_ID (unitless)\nEVTNBR (unitless)\nDATE_UTC (unitless)\nTIME_UTC (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\n...

Samples were filtered at 0.4 \\u03bcm immediately after collection through polycarbonate track etched filters (Nucleopore) into 250 mL HDPE bottles and acidified to 0.012 M hydrochloric acid (ultrapure by quadruple distillation in a Vycor still; ~pH 2) at sea. Sampling and filtration followed published protocols used previously at Station ALOHA, for direct comparison (Fitzsimmons et al., 2015).

Additionally, concentrations of size-fractionated (0.6-5 µm and >5 µm) chlorophyll a and biogenic silica (bSi); size-fractionated (0.4-5 µm and >5 µm) labile particulate elemental phosphorus (P), Ni, and Cd; and particulate organic carbon and nitrogen (POC and PON, respectively) from these four incubations was measured. Treatments included various additions of macronutrients and/or iron (Fe) to either induce severe nutrient stress or relieve nutrient limitation. For each incubation, triplicate initial control samples were collected and then triplicate samples from each treatment were collected on the final day. This study provides insight into the macronutrient-micronutrient levers that may be responsible for the lack of full dissolved Ni depletion in ocean surface waters by marine phytoplankton.\n\ncdm_data_type = Other\nVARIABLES:\nCRUISE (unitless)\nSAMPLE_DATE (unitless)\nJULIAN_DAY (unitless)\nEPOCH (unitless)\nEPOCH_DAY (unitless)\nINCUBATION (unitless)\nTIMEPOINT (unitless)\nTREATMENT (unitless)\nREPLICATE (unitless)\nPHOSPHATE (micromolar (µM))\nPHOSPHATE_flag (unitless)\nSILICIC_ACID (micromolar (µM))\nSILICIC_ACID_flag (unitless)\nNITRITE (micromolar (µM))\nNITRITE_flag (unitless)\n...

Preliminary studies had indicated that groundwater may supply both dissolved organic nitrogen (DON) and iron in this region. In coastal ecosystems like the West Florida Shelf that have very low nitrate and ammonium concentrations, DON is the main form of nitrogen available to organisms. Nitrogen cycling is strongly affected by iron availability because iron is essential for both photosynthesis and for nitrogen fixation. This study investigated the sources and composition of DON and iron, and their influence on the coastal ecosystem. The team sampled offshore groundwater wells, river and estuarine waters from shore, and conducted two expeditions across the West Florida Shelf in winter and summer for surface and depth profile sampling and for shipboard incubation experiments.\n\ncdm_data_type = Other\nVARIABLES:\nSTING_ID (unitless)\nCRUISE_ID (unitless)\ntime (Datetime_utc, seconds since 1970-01-01T00:00:00Z)\nDATETIME_LOCAL_ET (unitless)\nDATE_LOCAL (unitless)\nTIME_LOCAL (unitless)\nTIME_ZONE (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nSTN (unitless)\nSAMPLE_ID (unitless)\nSAMPLE_DESC (unitless)\nSITE_TYPE (unitless)\nPLATFORM (unitless)\n...
