This dataset contains biological and chemical data collected from 2015-05-11 to 2015-07-27. These data include chl_tot, chlorophyll a, and pCO2. The instruments used to collect these data include UV Spectrophotometer-Shimadzu. These data were collected by Dr Janet E Kubler and Dr Steve Dudgeon of California State University Northridge as part of the "Ocean Acidification: Scope for Resilience to Ocean Acidification in Macroalgae (Seaweed OA Resilience)" 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 2019-06-05.

The following is the text of the dataset description provided by BCO-DMO:

Supplemental Information	Acquisition Description: Culture pots were placed in large thermally insulated coolers in a temperature-controlled water bath at 15° C under saturating illumination of ~550 µmoles photons/m^2/s on a 12:12 L:D cycle. pCO2 treatments were supplied to closed culture pots by use of a gas mixing system combining nitrogen, oxygen and carbon dioxide to specific CO2 partial pressures, 20.9% oxygen and the balance being nitrogen. Chlorophyll a was extracted from Ulva tissue following the procedure described in Duncan and Harrison (1982). Chlorophyll a concentrations were measured using a Shimadzu UV-2450 UV-visible spectrophotometer.
