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: | Calcification rates from pH experiments on Lophelia pertusa specimens collected from the Norwegian Skagerrak and the Gulf of Mexico (Lophelia OA project) on 2016-09-20 (NCEI Accession 0278866) |
| Abstract: | This dataset contains biological and chemical data collected at lab Cordes during deployments Gulf_of_Mexico and Tisler_Reef at Gulf of Mexico; Norwegian Skagerrak on 2016-09-20. These data include growth and total alkalinity. The instruments used to collect these data include Dissolved Oxygen Sensor, Oxygen Microelectrode Sensor, and Scale. 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 2019-05-10. The following is the text of the dataset description provided by BCO-DMO: Calcification rates from pH experiments on L. pertusa. Dataset Description: Calcification data from pH manipulation experiments on Lophelia pertusa . Specimens were collected from Tisler Reef in the Norwegian Skagerrak and from the Gulf of Mexico.

| Supplementary information: | Acquisition Description: Acquisition Description for Tisler Reef Data: Net calcification was measured using the total alkalinity anomaly (Smith & Key 1975; Ohde & Hossain 2004). Corals were individually placed in closed glass chambers (220 ml) in a water bath that maintained temperature to +/-0.2 degrees C during all trials. To avoid hypoxia or the severe reductions of pH during incubations, ambient air was continuously bubbled into the chambers at a slow rate (1-2 bubbles s-1). This also provided adequate circulation within the chamber. A 60 ml water sample was collected by syringe before and after the incubation period, and measured for total alkalinity in duplicate. The respiration rate of each colony was measured as oxygen consumption in a 400 ml closed acrylic chamber during hour-long incubations. Dissolved oxygen concentrations were measured in umol L-1 using a Strathkelvin 782 dual oxygen meter and SI130 microcathode electrode. The feeding rate of each colony was measured as the capture rate of adult Artemia salina during a one-hour period in 0.8 L incubation chambers containing a starting prey density of 125 Artemia L-1. Acquisition Description for Gulf of Mexico Data: The buoyant weight of each colony was obtained at the start and end of the two-week experimental period by weighing fragments submerged in seawater and attached by a hook to an analytical balance (Denver Instrument, precision of 0.1 mg). The respiration rate of each colony was measured as oxygen consumption in an 800 ml closed acrylic chamber during hour-long incubations. Dissolved oxygen concentrations were measured in umol L-1 using a Strathkelvin 782 dual oxygen meter and SI130 microcathode electrode. The feeding rate of each colony was measured as the capture rate of adult Artemia salina during a one-hour period in 0.8 L incubation chambers containing a starting prey density of 125 Artemia L-1. |
