    String summary "Beryllium-7 (Be-7) is a radioactive isotope with a half-life of 53.3 days. It is formed in the atmosphere, attaches to aerosol particles, and is subsequently deposited to the Earth's surface by wet and dry deposition processes. As part of the GEOTRACES GP17-ANT project, we measured Be-7 concentrations in surface ocean seawater (depths <200 meters) samples collected from six stations and bulk aerosol particles collected across eight deployments in the Southern Ocean and Amundsen Sea region. Samples were collected aboard the research vessel ice breaker Nathaniel B. Palmer during cruise NBP2401 (29 November 2023 to 28 January 2024). The dataset will be used to calculate bulk atmospheric deposition velocities across the study region, based on the premise that Be-7 inventory in the surface ocean is controlled primarily by atmospheric deposition and radioactive decay. Thus, from the surface Be-7 inventory, its deposition flux can be determined, and from that and the aerosol Be-7 concentration, we can determine deposition velocity. The determined deposition velocity will then be used with aerosol concentrations of trace elements measured during the same study to determine rates of atmospheric supply of trace elements to the region.";

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.
