    String summary "Quantifying the direction and magnitude of CO2 flux in estuaries is necessary to constrain the global carbon cycle, yet carbonate systems and CO2 flux in subtropical and urbanized estuaries are not yet fully determined. To estimate the CO2 flux for Galveston Bay, a subtropical estuary located in the northwestern Gulf of Mexico proximal to the Houston-Galveston metroplex, monthly cruises were conducted along a transect extending from the Houston ship channel to the mouth of Galveston Bay and Gulf of Mexico from October 2017 to September 2018. Surface samples were collected at each of five stations in the Bay and analyzed for chlorophyll-a. Chlorophyll-a concentrations varied spatially and temporally throughout the study period and were highest in the inner Bay in late winter (February) and at all stations in mid-spring (April), following the freshwater inflow event. Stations 4 and 5 (inner Bay, closest to the San Jacinto River mouth) had early peak chlorophyll-a concentrations in February of 2018 (39.9 and 63.3 µg L-1, respectively), whereas mid- and outermost sampling locations 1, 2, and 3 peaked in mid-April (28.2, 44.2, and 35.8 µg L-1, respectively). Slight increases in chlorophyll-a were observed at stations 4 and 5 in July and September of 2018. When compared with carbonate chemistry data, it appears that large freshwater inflows in late winter and early spring stimulated photosynthesis in the Bay, leading to an influx of atmospheric CO2.";

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.
