String acquisition_description
"Plocamium cartilagineum was collected from Santa Catalina Island and Leo
Carollo, CA in June - Nov. 2014 and Jan. 2015.
Carbonate chemistry parameters were measured by sampling pH and total
alkalinity (TA) of water samples. Seawater samples from each culture pot
during all 7 trials were collected approximately every other day in 50 ml
Falcon tubes to verify experimental treatment conditions. Water samples were
measured usually within 1-2 hours of sample collection. 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.
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.
See Supplemental Files for a table of culture conditions for each of the 8
trials (pdf).";

String projects_0_description "Benthic macroalgae contribute to intensely productive near shore ecosystems and little is known about the potential effects of ocean acidification on non-calcifying macroalgae. 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.";

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.
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.
