"Plocamium cartilagineum\\u00a0was collected from Catalina Island in June - Nov.
2014 and Jan. 2015.
 
Seawater samples were collected over a 30-hour time course of pH drift
experiments with Plocamium cartilagineum to test mechanism of carbon
acquisition by alga and the effect on carbonate chemistry parameters reported
in these datasets. Samples were collected at 0, 2, 6, 20, 24 and 30 hours and
parameters of carbonate chemistry were measured (DIC,CO2, HCO3,CO3-described
below). pH drift assay experiments consisted of 2 independent variables;
inhibitor treatment and algal presence, with 3 and 2 levels, respectively for
each independent variable (see parameters section). Two replicate water
samples were collected from each of 9 experimental culture pots of algae grown
for 3 weeks at different combinations of pCO2 and temperature during each of 7
experimental trials.
 
Carbonate chemistry parameters were measured by sampling pH and total
alkalinity (TA) of water samples. pH was determined using the m-cresol
indicator dye method in a spectrophotometer (Dickson et al. 2007). TA samples
were analyzed by potentiometric titration coupled to a pH electrode calibrated
using certified reference material (CRM) from the Dickson laboratory at
Scripps Oceanographic Institute and the pH electrode calibrated using TRIS
buffer (Dickson et al. 2007). TA and carbonate parameters were calculated from
potentiometric titration data and spectrophotometric pH data.

Ocean CO2 Measurements.
 
Note: Trial 1 was a pilot test of culture system and methodological procedures
so was not used for data collection in the testing of hypotheses.

Kübler and Dudgeon will test  hypotheses about two macroalgae, Ulva spp. and Plocamium cartilagineum,  which, for different reasons, are hypothesized to be more productive  and undergo ecological expansions under predicted changes in ocean  chemistry. They have designed laboratory culture-based experiments to  quantify the scope for response to ocean acidification in Plocamium,  which relies solely on diffusive uptake of CO2, and populations of Ulva  spp., which have an inducible concentrating mechanism (CCM). The  investigators will culture these algae in media equilibrated at 8  different pCO2 levels ranging from 380 to 940 ppm to address three key  hypotheses. The first is that macroalgae (such as Plocamium  cartilagineum) that are not able to acquire inorganic carbon in changed  form will benefit, in terms of photosynthetic and growth rates, from  ocean acidification. There is little existing data to support this  common assumption. The second hypothesis is that enhanced growth of Ulva  sp. under OA will result from the energetic savings from down  regulating the CCM, rather than from enhanced photosynthesis per se.  Their approach will detect existing genetic variation for adaptive  plasticity. The third key hypothesis to be addressed in short-term  culture experiments is that there will be a significant interaction  between ocean acidification and nitrogen limited growth of Ulva spp.,  which are indicator species of eutrophication. Kübler and Dudgeon will  be able to quantify the individual effects of ocean acidification and  nitrogenous nutrient addition on Ulva spp. and also, the synergistic  effects, which will inevitably apply in many highly productive, shallow  coastal areas. The three hypotheses being addressed have been broadly  identified as urgent needs in our growing understanding of the impacts  of ocean acidification.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP Data Access Protocol (DAP) and its selection constraints.

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

• (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
• (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
• (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
