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: | Retinal responses during exposure to decreasing oxygen partial pressure (pO2) on 2019-10-23 (NCEI Accession 0292217) |
| Abstract: | This dataset contains biological, chemical, and survey - biological data collected at Souther California Bight, Northeast Pacific Ocean on 2019-10-23. These data include dissolved Oxygen and species. The instruments used to collect these data include Oxygen Microelectrode Sensor. These data were collected by Dr Lisa A Levin and Nicholas Oesch of University of California-San Diego as part of the "Vision-mediated influence of low oxygen on the physiology and ecology of marine larvae (Vision under hypoxia)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-11-01. The following is the text of the dataset description provided by BCO-DMO: Dataset Description: Retinal responses during exposure to decreasing oxygen partial pressure (pO2) in marine invertebrate larvae determined with electroretinograms. Please see additional datasets for this paper, including the “OxygenMetrics_Vision” and the “Experiment_Metrics” datasets. |

| Supplementary information: | Acquisition Description: Detailed methods can be found in McCormick et al., 2019 Briefly, the time series test recorded electroretinogram (ERG) responses to a 1 s square step of light at a constant irradiance of 3.56 μmol photons m − 2 s − 1 repeated every 20 s, providing a nearly continuous measure of ERG response in a tethered, live larva during the experimental manipulation of partial pressure of oxygen (pO2). There was a constant flow of pH-buffered sterile seawater in the chamber where the larva was held, and after a brief period in “normoxia” (surface-ocean oxygen levels), the pO2 was decreased, and then held at a low pO2 before re-oxygenating the solution. This dataset shows the retinal responses measured every 20 s for all individuals used in Figure 1 (top panel) of McCormick et al., 2019. The retinal responses show a decline in retinal function during a decrease in oxygen availability. Oxygen was measured using a Microx4 (PreSens) oxygen meter and a Pst-7 oxygen optode probe. |
