The EXPORTS field campaign in the subarctic North Pacific sampled an ecosystem characterized as high nutrient low chlorophyll (HNLC) due to low iron (Fe) levels that are primary controllers constraining phytoplankton utilization of other nutrients. It has been a paradigm in low Fe, HNLC systems that diatoms grow at elevated Si:C and Si:N ratios and should be efficiently exported as particles significantly enriched in Si relative to C. However, Fe limitation also alters diatoms species composition and the high Si demand imposed by low Fe can drive HNLC regions to Si limitation or Si/Fe co-limitation. Thus, the degree of Si and/or Fe stress in HNLC waters can all alter diatom taxonomic composition, the elemental composition of diatom cells, and the path cells follow through the food web ultimately altering diatom carbon export.\\r\\n\\r\\nWithin each ecosystem state examined in the EXPORTS program, nutrient biogeochemistry, diatom and phytoplankton community structure, and global diatom gene expression patterns (metatranscriptomics) are characterized in the lit ocean. Nutrient amendment experiments with tracer addition (14C, 32Si) are used to quantify the level of Si and Fe stress being experienced by the phytoplankton and to contextualize taxa-specific metatranscriptome responses for resolving gene expression profiles in the in situ communities.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nDate_Zulu (unitless)\nTime_Zulu (unitless)\nEvent_num (unitless)\nActivity (unitless)\nStation (unitless)\nCast (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nRosette_Bottle (unitless)\ndepth (Target Depth, m)\npcnt_lo (unitless (percent))\n...

In the Event Log for RR2311, transect stations are designated \"T\" and process stations are designated \"PS\". Nutrients were collected on the first cast upon arrival at a process station, and in one case on the last day, of a 2-5 day station occupation.\n\nAmmonium concentrations were initially planned to be measured in high-resolution depth profiles at each major process and transect station. However, due to the exceedingly low concentrations detected by the shipboard method, only the data from the first process station were included, with remaining samples frozen for later analysis ashore. Ammonium concentration was measured manually using fluorometric methods (Holmes et al. 1999), with water collected using Niskin bottles. Five ml volumes were analyzed immediately upon retrieval without filtration.\n\nHigh-resolution profiles were also obtained for nitrite measurements at both process and transect stations. Nitrite concentration was determined manually using colorimetric methods (Hansen and Koroleff 1999) on duplicate samples, measured immediately after collection without filtration.\n\ncdm_data_type = Other\nVARIABLES:\ntime (Ctd_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nDate_Local (unitless)\nlatitude (Ctd_latitude, degrees_north)\nLat_Deg (degrees)\nLat_Min (minutes)\nlongitude (Ctd_longitude, degrees_east)\nLong_Deg (degrees)\nLong_Min (minutes)\nStation (unitless)\nCast_Number (unitless)\nNiskin_Bottle (unitless)\ndepth (Ctd_depth, m)\nTarget_Depth (m)\nNitrite (micromolar (uM))\nNH4 (micromolar (uM))\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_931516_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_931516_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_931516_v1/index.htmlTable | https://www.bco-dmo.org/dataset/931516![]() | https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_931516_v1.rss | https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_931516_v1&showErrors=false&email= | BCO-DMO | bcodmo_dataset_931516_v1 | |||
