The existence of a size-reactivity continuum of DOM - observations and measurements showing that high molecular weight (HMW) DOM tends to be younger and more reactive than lower MW DOM - has been demonstrated in laboratory and field investigations in different parts of the ocean. A mechanistic explanation for the greater reactivity of HMW DOM has been lacking, however.  \n \nHere we investigated the potential of seawater microbial communities from different water masses and under differing conditions of organic matter availability to hydrolyze six high-molecular-weight polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan). Samples were taken from incubation experiments of DCM, OMZ, and bottom waters aboard R/V Endeavor (EN638), May 2019 in the Northern Atlantic.\n \nThis dataset includes the measurement of cell abundance from samples taken from mesocosm incubations after the addition of HMW DOM.\n\ncdm_data_type = Other\nVARIABLES:\nDeployment (unitless)\nStation (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\ntime_sampled_EDT (unitless)\ntime (Time_sampled_utc, seconds since 1970-01-01T00:00:00Z)\ncast_number (unitless)\ndepth_sequence (unitless)\ndepth (Depth_m, m)\nin_situ_temp (degrees Celsius)\nincub_temp (degrees Celsius)\nsample_type (unitless)\nunammended_ammended (unitless)\n...

Sample collection occurred June 16-17, 2015. Each incubation was injected with 10 microliters of methylcyclohexane (MCH) or methylcyclopentane (MCP). Each incubation was monitored for oxygen content using remote optical oxygen sensors. After we observed a respiration signal, we sacrificially harvested each bottle for cell counts, nutrients, and DNA. Incubation time varied from 10-31 days. These data were used to assess who consumes these compounds in the deep Gulf of Mexico, over what time frame, and what metabolic pathways bacteria use to consume them.\n\ncdm_data_type = Other\nVARIABLES:\nRank (unitless)\nType (unitless)\nStation (unitless)\nlatitude (Station_latitude, degrees_north)\nlongitude (Station_longitude, degrees_east)\nISO_DateTime_Local (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nPhosphate (micromolar (uM))\nNitrite (micromolar (uM))\nAmmonia (micromolar (uM))\nNitrate (micromolar (uM))\nTotal_Oxygen_Loss (micromolar (uM))\nNormalized_Oxygen_Loss (micromolar (uM))\nTotal_Incubation_Time_Days (days)\nCell_Abundance (cells per milliliter (cells/mL))\nBloom_Onset_Time_Days (days)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_914186_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_914186_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_914186_v1/index.htmlTable https://www.bco-dmo.org/dataset/914186 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_914186_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_914186_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_914186_v1
