The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Experimental seawater chemical properties for larval mussel shell study from SIO, UCSD from 2012-2013 (OA_Proxies project) (NCEI Accession 0278542) |
| Abstract: | This dataset contains biological, chemical, physical, and survey - biological data collected at SIO Levin during deployment Levin_mussels from 2012-05-05 to 2013-01-23. These data include Aragonite Saturation State, Partial pressure of CO2, dissolved Oxygen, pH, salinity calculated from CTD primary sensors, species, total alkalinity (TA), and water temperature. The instruments used to collect these data include Aanderaa Oxygen Optodes, Inductively Coupled Plasma Mass Spectrometer, Mass Flow Controller, Water Temperature Sensor, density meter, and pH Sensor. These data were collected by Lisa A Levin of University of California-San Diego as part of the "Development of geochemical proxies to evaluate larval pH-exposure history (OA_Proxies)" project and "Science, Engineering and Education for Sustainability NSF-Wide Investment (SEES): Ocean Acidification (formerly CRI-OA) (SEES-OA)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-10-01. The following is the text of the dataset description provided by BCO-DMO: Experimental seawater chemical properties for larval mussel shell study Dataset Description: Experimental seawater chemical properties for larval mussel shell study from SIO, UCSD from 2012 and 2013. This table has been modified from tables in Frieder et al. 2014 GCB and Frieder et al. 2014 ES&T; see those publications for additional corresponding salinity and other carbonate chemistry variables. |

| Supplementary information: | Acquisition Description: Mass flow controllers were used to deliver a gas mixture of N2, O2, and CO2 to gas membrane contactors (Liqui-Cel Part No. G501), which in turn delivered the gas mixture to the seawater to maintain the desired CO2 and O2 concentrations in each treatment replicate (Bockmon et al. 2013, Biogeosciences). A pH sensor (Honeywell Durafet III) and Aanderaa oxygen optode were used to continuously record from one replicate per treatment, per day. Along with daily discrete samples measured for pH and [O2], this sensor monitoring confirmed the stability of conditions, with the average offset of replicates to be 0.01 pH units and 3µmol O2 kg-1 (Frieder et al. 2014, GCB). Discrete pH measurements were determined spectrophotometrically and the discrete [O2] values were determined using a Winkler Titration method (as described in Frieder et al. 2014, GCB). Discrete samples were taken at the beginning and end of each experiment for the determination of total alkalinity and salinity. Total alkalinity measurements were determined using an open-cell, potentiometric titration with an accuracy of +- 2 µmol kg-1 (Dickson et al., 2007). Salinity was calculated from density measured at 20°C on a Density Meter (Mettler Toledo DE45) with an accuracy of 0.05 salinity units. HOBO Pendant temperature data loggers with an accuracy of +-0.5°C continuously measured temperature every 5 min in all replicates. |
