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: | Total alkalinity during coral calcification experiments conducted on Oahu, Hawaii from November of 2014 to November of 2015 (NCEI Accession 0277397) |
| Abstract: | This dataset contains chemical data collected at shoreside Oahu during deployment RAPID_Hawaii_2014_2015 from 2014-11-17 to 2015-11-27. These data include total alkalinity. These data were collected by Robert J. Toonen of Hawaii Institute of Marine Biology and Dr Andrea G. Grottoli of Ohio State University as part of the "Will corals recover from bleaching under ocean acidification conditions? (RAPID Hawaii)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23. The following is the text of the dataset description provided by BCO-DMO: Total alkalinity Dataset Description: This dataset contains total alkalinity records for eight aquaria between Nov 17th, 2014 to Nov 27th, 2015 which were used in coral calcification experiments conducted on Oahu, Hawaii. Datasets relevant to this experiment: * * pH * water temperatures * coral calcification |

| Supplementary information: | Acquisition Description: About weekly, bottle samples were also collected for total alkalinity and pH. Bottles were rinsed with sample repeatedly before sample collection. Alkalinity samples were collected in borosilicate glass bottles without air space, and were analyzed via a modified Gran titration using an 877 Titrino plus, typically within 3 hr of collection, though they appeared to be stable for at least 7 days. Titrations were verified using Certified Reference Materials obtained from Andrew Dickson and precision and accuracy were typically +-10 ueq/kg or better. pH samples were collected in 50 ml centrifuge tubes without air space and analyzed spectrophotometrically with m-cresol purple, following standard protocols, and typically within 1 hr of collection, though they appeared to be stable for at least 24 hr. Precision of pH analyses was typically +-0.002 units or better, while accuracy of this method is estimated as +-0.02 units or better. Tank treatments: Below, "High" or "Low" pH refers to target pH levels. "Fed" or "Unfed" refers to whether the tank was fed zooplankton not. Tank t1: High pH, Unfed Tank t2: High pH, Fed Tank t3: Low pH, Unfed Tank t4: Low pH, Fed Tank t5: High pH, Fed Tank t6: Low pH, Unfed Tank t7: Low pH, Fed Tank t8: High pH, Unfed Location information: The coral collection sites were the reef around HIMB and the reef adjacent to Kaiona Beach Park in Waimanalo (about 1 mile north of the Makai Pier). The lat/long for the approximate center of the sampling area at each site are as follows, and the sampling at each site was located within about +/- 200 m of that central point: Kane'ohe Bay: 21.4336 N, -157.7861 W Waimanalo Bay: 21.3272 N, -157.6811 W The tank experiments were conducted at the Point Lab on Coconut Island, which is ~18 km from the sampling area in Waimanalo Bay and adjacent to the sampling area in Kane'ohe Bay. The high pH treatment was ambient Kane'ohe Bay seawater chemistry (pH ~7.9-8.0) whereas the target for the low pH treatment was ~0.25 units below ambient. |
