Experimental and survey biogeochemical and microbial data from R/V Point Sur cruises PS1009 and PS1103 in the Santa Barbara Channel from 2010-2011 (SBDOM project, SBC LTER project) (NCEI Accession 0277943)
This dataset contains biological, chemical, optical, and physical data collected on R/V Point Sur during cruises PS1009 and PS1103 from 2010-04-09 to 2011-05-16. These data include Dissolved Organic Nitrogen, Nitrite, PAR, SiOH_4, bacterial abundance, chl_tot, chlorophyll a, conductivity, conductivity from the CTD secondary sensor, depth, depth_bottom, dissolved Oxygen, dissolved organic Carbon, fluorescence, nitrate plus nitrite, particulate organic Carbon (POC), particulate organic nitrogen, reactive phosphorus (PO4), salinity calculated from CTD primary sensors, salinity calculated from the CTD secondary sensors, sigma-theta, temp2, total phaeopigment, water pressure, and water temperature. The instruments used to collect these data include CTD TRIAXUS and Flow Injection Analyzer. These data were collected by Dr Craig Carlson and Mark Brzezinski of University of California-Santa Barbara as part of the "Mechanisms controlling the production and fate of DOM during diatom blooms (SBDOM)" and "Santa Barbara Coastal Long Term Ecological Research site (SBC LTER)" projects and "Long Term Ecological Research network (LTER)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-08-28.

Supplemental Information | Acquisition Description: Description of methods from cruise plans and project proposal: Triaxus and CTD operations were conducted from the R/V Point Sur within the Santa Barbara Channel. Samples were collected for particulates and dissolved constituents. Determinations of phytoplankton productivity were made using 14C, 15NO3 and 32Si incorporation using on-deck incubator. Measurements of microbial activity, biomass and DNA. 3H-Leucine were used to assess bacterial production. Deck board incubation experiments were also conducted. The Triaxus survey was used to assess fluorescence and to target the areas of water collection for experimental work. A 24-station CTD grid was performed on each cruise. A full suite of particulate and dissolved nutrients were measured, along with bacterial and phytoplankton productivity measurements. Two large incubation experiments were conducted onboard using deck incubators. Assays of nutrient stress: Phytoplankton nutrient stress at each grid station were quantified by measuring the uptake rate of silicic acid and nitrate at the ambient concentration and then again after the addition of a saturating level of the nutrient. Tracers, 15NO3 or 32Si(OH)4, were added to replicate subsamples. One of the subsamples was unaltered to yield the rate of nitrate or Si uptake under ambient nutrient concentrations. The second sample in each pair received a saturating addition of the nutrient whose uptake was being monitored, yielding the uptake rate under conditions of nutrient sufficiency. Isotopic 14C tracer experiments: The methods of Lancelot and Mathot (1985) were modified to track primary production (PP), dissolved organic Carbon (DOC) extracellular release, fraction of released DOC incorporated by bacterioplankton and the fraction that’s resistant to rapid remineralization. |
