log in [2017 GO-SHIP P06 transect TDN d15N] - Total dissolved nitrogen (TDN) concentrations and δ15N measurements from samples collected on R/V Nathaniel B. Palmer GO-SHIP cruises NBP1706 and NBP1707 in the South Pacific from Jul 3 to Sep 30, 2017 (Collaborative Research: Dissolved organic phosphorus controls on marine nitrogen fixation and export production) This dataset includes total dissolved nitrogen (TDN) concentrations and their d15N measurements from samples collected in the upper ~300 m along the 2017 GO-SHIP P06 transect from 3 July to 30 September 2017 on R/V Nathaniel B. Palmer GO-SHIP cruises NBP1706 and NBP1707. Samples were collected roughly every 2 degrees of longitude across the transect. Samples were measured using persulfate oxidation of the TDN in the sample to nitrate, and then using the denitrifier method to measure the d15N of the resulting nitrate. \n \nDissolved organic nitrogen (DON) is the dominant form of bioavailable nitrogen in the euphotic zone of subtropical gyres, where nitrate (NO3-) concentrations are low. However, identifying regions where DON consumption may support surface ocean productivity remains challenging due to the relatively narrow range in euphotic zone DON concentrations. These paired measurements of TDN concentrations and their d15N values will help resolve patterns of DON production and consumption across the largest subtropical ocean gyre.\n\ncdm_data_type = Other\nVARIABLES:\nEXPOCODE (unitless)\nSECT_ID (unitless)\nSTNNBR (unitless)\nCASTNO (unitless)\nNiskin_bottle_number (unitless)\nDATE (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCTDPRS (decibars)\nCTDSAL (practical salinity units)\nCTDTMP (degrees centigrade)\nNITRAT_plus_NITRIT (micromolar (µM))\nTDN (micromolar (µM))\nTDN_d15N (Per mil units relative to atmospheric N2 gas)\n BCO-DMO bcodmo_dataset_986627_v1

Sproul during nine cruises from 2018-2022 from the Oregon and Washington shelf (Benthic Biogeochemical Exchange Dynamics on the Oregon Shelf) Continental shelf sediments are sinks for dissolved oxygen and sources of many major and minor nutrients required for oceanic surface primary production, resulting in a strong coupling between benthic and pelagic biogeochemical cycling. However, the influence and spatiotemporal variability of benthic remineralization on bottom-water chemistry and the supply of nutrients to surface waters has received minimal study on the Oregon-Washington (OR-WA) shelf. To expand knowledge of these areas, benthic flux measurements were made approximately quarter-annually at inner-shelf and mid-shelf sites on the Newport Hydrographic (NH) Line at 44.6˚N between December 2017 and July 2019, and again between 44.5˚N and 46.5˚N along the mid-shelf during July and September of 2022. The benthic fluxes were determined using a novel set-up for ex situ core incubations. The dataset described here details all benthic fluxes measured during sediment incubation experiments, conducted during the cruises from February 2018 to July 2019, at the sites on the NH Line, and during July and September of 2022. The paired bottom water dataset is located in a separate BCO-DMO dataset (dataset ID 793115). Additionally, during the 2022 cruises, community composition data were collected using box corers.

The ability of natural assemblages of bacteria to utilize DOM produced under Si and N limitation was then assessed using remineralization experiments. Species examined in the remineralization experiments include: Skeletonema marinoi, Chaetoceros socialis, Thalassiosira weissflogii, and Odontella aurita.\n\ncdm_data_type = Other\nVARIABLES:\nspecies (text)\ntreatment (text)\nreplicate (integer)\ntime_point (integer)\ndays_elapsed (number)\nDOC (micromoles per Liter (umol/L))\nDOC_sd (micromoles per Liter (umol/L))\nTDN (micromoles per Liter (umol/L))\nTDN_sd (micromoles per Liter (umol/L))\nNO3_NO2 (micromoles per Liter (umol/L))\nNH4 (micromoles per Liter (umol/L))\nPO4 (Mass Concentration Of Phosphate In Sea Water, micromoles per Liter (umol/L))\ndSi (D Si, micromoles per Liter (umol/L))\nbact_abund_FCM (cells per Liter (cells/L))\nbact_abund_DAPI (cells per Liter (cells/L))\nbact_abund_DAPI_sd (cells per Liter (cells/L))\nbact_prod (picomoles Leucine per Liter per hour (pmol Leu/L/hr))\nbact_prod_sd (picomoles Leucine per Liter per hour (pmol Leu/L/hr))\nspecifc_growth_rate (per day)\nbact_growth_eff (unitless)\nDNA_sampled (yes or no)\n https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_518508/index.htmlTable https://www.bco-dmo.org/dataset/518508 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_518508.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_518508&showErrors=false&email= BCO-DMO bcodmo_dataset_518508
log in [STING 1 TDN and TDP concentration] - Total dissolved nitrogen (TDN) and total dissolved phosphorus (TDP) of samples collected on the West Florida Shelf during STING I cruise AE2305 on R/V Atlantic Explorer from Feb 20 to Mar 05, 2023 (Collaborative Research: Linking iron and nitrogen sources in an oligotrophic coastal margin: Nitrogen fixation and the role of boundary fluxes) The West Florida Shelf (WFS) is oligotrophic, with inorganic N and P concentrations typically at or below detection limits, and yet significant rates of primary productivity, including blooms of the cyanobacterial diazotroph Trichodesmium spp. as well as the harmful algal species Karenia brevis, are observed there. Consequently, dissolved organic nitrogen (DON) and dissolved organic phosphorus (DOP) are thought to be the primary sources of assimilative nutrients on the WFS. Here we report measurements of total dissolved nitrogen (TDN) and total dissolved phosphorus (TDP) concentrations made on samples collected on a cross-shelf cruise in Feb-Mar 2023 aboard the R/V Atlantic Explorer. Elevated concentrations of TDN (>12 µM) and TDP (>0.5 µM) were observed in the shallow, nearshore region, while to the west concentrations of both TDN and TDP decreased to values typically associated with oligotrophic North Atlantic waters (4 to 5 µM TDN and 0.05 to 0.1 µM TDP).\n\ncdm_data_type = Other\nVARIABLES:\nCRUISE_ID (unitless)\nSTING_ID (unitless)\nEVTNBR (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nDATE_UTC (unitless)\nTIME_UTC (unitless)\nDATE_GMT (unitless)\nTIME_GMT (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nPLATFORM (unitless)\nCASTNBR (unitless)\nSTNNBR (unitless)\nBTLNBR (unitless)\ndepth (m)\nTDP (micromoles per liter (µM))\nTDP_STDEV (micromoles per liter (µM))\nTDP_COUNT (replicate)\n...
