Project: Diatoms and carbon export Name: BCO-DMO Email: info@bco-dmo.org Institution: BCO-DMO InfoURL: https://www.bco-dmo.org/dataset/786013 Source URL: (local files) Unknown tabular digital data Woods Hole, MA, USA ERDDAP, version 2.22, at BCO-DMO https://erddap.bco-dmo.org/erddap/tabledap/bcodmo_dataset_786013.html https://erddap.bco-dmo.org/erddap/tabledap/bcodmo_dataset_786013.graph https://erddap.bco-dmo.org/erddap/tabledap/bcodmo_dataset_786013.subset Diatoms and carbon export 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.
