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: | Water samples from CTD casts and vehicle-mounted bottles from the R/V Atlantis, NOAA Ship Ronald H. Brown, R/V Falkor, & E/V Nautilus in the Gulf of Mexico & Florida from 2010 to 2014 (Lophelia OA project) (NCEI Accession 0278300) |
| Abstract: | This dataset contains chemical and physical data collected on E/V Nautilus, NOAA Ship Ronald H. Brown, R/V Atlantis, and R/V Falkor during cruises AT26-14, FK004E, NA028, and RB1007 in the Gulf of Mexico from 2010-01-01 to 2014-12-31. These data include Aragonite Saturation State, depth, dissolved inorganic Carbon, pCO2, pH, salinity calculated from CTD primary sensors, total alkalinity, water pressure, and water temperature. The instruments used to collect these data include Aquarium, Automatic titrator, Bottle, CTD profiler, Water Temperature Sensor, and pH Sensor. These data were collected by Dr Erik E. Cordes and Dr Robert J. Kulathinal of Temple University as part of the "Physiological and genetic responses of the deep-water coral, Lophelia pertusa, to ongoing ocean acidification in the Gulf of Mexico (Lophelia OA)" 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 2019-05-13. The following is the text of the dataset description provided by BCO-DMO: Water samples from CTD casts and vehicle-mounted bottles from 4 cruises. Dataset Description: Water samples from CTD casts and vehicle-mounted bottles collected on the Atlantis, GOMRI, Nautilus, Ronald H. Brown, and Schmidt between 2010 and 2014. |

| Supplementary information: | Acquisition Description: pH was measured on the total hydrogen scale (pHT) within one hour of sample collection. Each water sample was placed in a 25 degrees C water bath for 10–20 minutes to standardize temperature (mean temperature over all pH measurements of 22.2 +/- 2.6 degrees C). pHT was then measured in duplicate using the Orion 5 Star pH meter and glass electrode (ROSS Ultra pH/ATC Triode 8107BNUMD) calibrated with Tris–HCL buffer solution obtained from the Dickson Lab (Batch 22). Electrode performance was regularly checked against standard Tris-HCl and AMP-HCl buffers in artificial seawater (Nemzer et al. 2005; Dickson et al. 2007). Temperature was measured using the integrated temperature sensor on the ROSS Ultra pH/ATC Triode from 2010–2013, and using a handheld thermocouple (Omega HH81A) in 2014. Total alkalinity (TA) was measured in triplicate by acid titration on a Mettler–Toledo DL15 autotitrator using 0.1 mol L–1 HCl buffered in 0.6 mol L–1 NaCl (modified from SOP 3b, Dickson et al. 2007). The autotitrator was calibrated daily on the NBS scale using certified reference buffers (Orion), and certified reference materials (Dickson Lab, batches 138 and 141) were measured periodically to ensure accuracy (within +/- 10 umol kg-1). |
