Porewater nutrient concentrations (NO3+NO2, NH4, and PO4) from pushcore samples collected at Guaymas Basin hydrothermal vents via Alvin dives on R/V Atlantis cruise AT42-05, Nov. 2018 (NCEI Accession 0277700)
This dataset contains chemical data collected on Alvin and R/V Atlantis during cruise AT42-05 and deployment AT42-05_Alvin_Dives in the Gulf of California from 2018-11-17 to 2018-11-25. These data include Ammonium, nitrate plus nitrite, and reactive phosphorus (PO4). The instruments used to collect these data include Nutrient Autoanalyzer and Push Corer. These data were collected by Andreas P. Teske of University of North Carolina at Chapel Hill and Dr Virginia P. Edgcomb of Woods Hole Oceanographic Institution as part of the "Collaborative Research: Hydrothermal Fungi in the Guaymas Basin Hydrocarbon Ecosystem (HOTFUN)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-07-31.

Guaymas pushcore nutrients
Dataset Description:
Porewater nutrient concentrations from pushcore samples collected at two locations in the Guaymas Basin hydrothermal vents region during Alvin dives on R/V Atlantis cruise AT42-05, Nov. 2018. NO3+NO2, NH4, and PO4 concentrations at different depths within the cores are reported.

Supplemental Information | Acquisition Description: Alvin pushcores dedicated to nutrient analyses were sectioned to recover the 0-6cm, 6-12, and 12-18cm fractions, or the 0-10, 10-20, and 20-30cm fractions. Two ~40ml samples of sediment were placed in 50 ml Falcon tubes and were centrifuged at 3000 rpm for 15 minutes to separate porewater from the sediment. After centrifugation, the porewater was filtered through sterile syringe cellulose 0.45 micron filters. 5 ml of the porewater was placed into 5 ml screwcap Eppendorf cryotubes stored without headspace at -20 degrees C for nitrate (NO3), nitrite (NO2) and phosphate (PO4) analysis. The headspace was flushed with nitrogen and the samples were stored inverted at 4 degrees C. All porewater analyses were performed at Louisiana State University Wetland Biogeochemistry Analytical Services. Dilution info: All samples @ 2x and various samples @ 20x , 50x , 70x , and/or 350x. |
