32Si and 14C production data (experimental) from EXPORTS cruise RR1813 on R/V Roger Revelle in the Subarctic North Pacific near Station PAPA from August to September 2018

Summary:
This dataset includes 32Si and 14C production data (experimental) from EXPORTS cruise RR1813. 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.

Acetic acid leachable trace metals from bulk aerosol samples collected during the US GEOTRACES EPZT section cruise (R/V Thomas G. Thompson TN303) in the Eastern Tropical Pacific from October to December 2013

Summary:
Atmospheric input is important to the biogeochemical cycling of trace metals in the ocean. The fraction of aerosol trace metals that can potentially dissolve after deposition is of interest for improving knowledge of aerosol/surface ocean interactions. This dataset provides acetic acid leachable trace metal values from bulk aerosol from the Equatorial Pacific along the US GEOTRACES EPTZ transect (TN303) from Peru to Tahiti. This region is characterized as one of the lowest atmospheric deposition regimes in the ocean. Bulk aerosols were collected from the boundary layer (~15 m above sea level) using a high-volume aerosol sampler drawing approximately 1.2 cubic meters of air per minute over Whatman 41 ash-less filter discs. Despite low aerosol loadings, triplicate agreement for most samples was good for Al, Ti, V, Mn, Fe, and Cu. Away from the coast, Cd and Pb values in most samples were close to, or below detection limit. Acetic acid leaches were carried out with a combination of 25% acetic acid and a reducing agent. Leachable trace metal concentrations were determined at the University of Alaska Fairbanks by inductively coupled plasma mass spectrometry (Thermo Element-2) using external calibration curves. The aerosol trace metal fractional solubility was calculated as a percent of the total bulk aerosol data from the same cruise (https://www.bco-dmo.org/dataset/675632).

CARIACO time series individual CTD profiles from B/O Hermano Gines HG93_CARIACO in the CARIACO basin from 1995-2017 (CARIACO project)

Summary:
This collection of data comprises all the Individual CTD profiles from the Cariaco basin taken as part of the CARIACO Ocean Time-Series Program from November 1995 to January 2017.  These include all the CTD profiles taken during the monthly hydrographic cruises at the CARIACO station (10.50\u00b0 N, 64.67\u00b0 W), as well as other CTD profiles from extra legs of the monthly cruises, and few spatial cruises collected in and around the Cariaco basin. CTD\u2019s Salinity and Oxygen where calibrated with in-situ measurements (see Acquisition Description). This dataset is complimentary to the monthly \u201cCTD Composite Profiles\u201d (https://www.bco-dmo.org/dataset/3092), and many fields are very similar to that data-base. The difference with that dataset, is that here we present all the CTD casts for each cruise, the CTD profiles are single (not composite), and the salinity and oxygen profiles were calibrated with in-situ measurements, but fluorescence was no calibrated.

Cellular elemental content of individual phytoplankton cells collected during US GEOTRACES North Atlantic Transect cruises in the Subtropical western and eastern North Atlantic Ocean during Oct and Nov, 2010 and Nov. 2011

Summary:
Individual phytoplankton cells were collected on the GEOTRACES North Atlantic
Transect cruises were analyzed for elemental content using SXRF (Synchrotron
radiation X-Ray Fluorescence). Carbon was calculated from biovolume using the
relationships of Menden-Deuer & Lessard (2000). Trace metal concentrations are
reported.

Coastal water biogeochemistry collected aboard the R/V Endeavor along the North Atlantic coast from 2017-08-20 to 2017-08-28

Summary:
Samples were collected from four water column sites along the Northeast Coast of the United States in August 2017 aboard the R/V Endeavor. Samples were collected using a 12-bottle trace metal clean CTD (Conductivity, Temperature and Depth) rosette, and were kept clean by using acid washed tubing to collect water directly into acid-washed 1 L PTFE bottles. Sample depths were chosen based on the water column profile obtained from a separate 24-bottle CTD rosette system equipped with Seabird software, which also provided the temperature, dissolved oxygen, salinity, PAR, beam transmission and fluorescence profiles reported here.

CTD data from ARSV Laurence M. Gould LMG1110 in the Southern Ocean from November to December 2011 (Salp_Antarctic project)

Summary:
This is from the cruise report (see LGM1110 deployment page for link) and
particulary pertains to the Fluorescence data that were collected:

\Preliminary CTD Results: A total of 20 CTD stations were occupied and
sampled during the cruise. Hydrographic data were collected in all sampling
regions of the study. Casts were sent to the shallower of 1,000 m or 5-10 m
above the bottom. The primary fluorometer was mis-calibrated (had the wrong
scale factor in the calibration/processing file), so fluorescence data from
the first four (or five) stations (Stns #22, #7, #8, #11) had to be re-
processed with the correct scaling factor. Examination of the *.cnv file
showed which casts had the miscalibrated data, as the max reading for
fluorescence was ~ 0.05 mg/m3. For nearly every other station, maximum
fluorescence readings were > 1.0 mg/m3. A secondary fluorometer was added to
the CTD rosette between Stns #11 and #12, which verified that the issue was
with the scale factor in the CTD processing software.\

The data that are served have warnings about fluorescence numbers in the
headers of the casts at Stations 22, 7, 8 and 11.

Variables that were part of the data that have been rendered invisible from
the data online are: Elapsed time in seconds, modulo error count (always
zero), and nbin (number of scans per bin). Those numbers are available upon
request.

Depth profiles of the isotopic composition (d30Si) of silicon within dissolved silicic acid on the US GEOTRACES Arctic cruise GN01 (HLY1502) from August to October 2015

Summary:
The isotopic composition of dissolved silicon (\u03b430Si) has proven to be a powerful tool to better understand the marine Si cycle. The \u03b430Si of seawater carries information about DSi utilization in surface waters, the subsequent dissolution of sinking biogenic material as well as water mass mixing. This data set supplies information on the spatial distribution of isotopes of Si within water masses in the Arctic Ocean from the Bering Strait to the north pole. Profiles of silicon isotopes within silicic acid, \u03b430Si(OH)4, were obtained at a total of 15 stations on the GEOTRACES GN01 cruise
