Particle samples were collected via sequential size fractionation using McLane in-situ pumps on two cruises conducted aboard the R/V Kilo Moana in February (KM1407) and September (KM1418) 2014. Data were collected as part of a project focused on characterizing sources of nutrition for the mesopelagic animal food web, for which particulate organic matter was a crucial baseline resource. In addition, differences in the nitrogen isotopic ratios of individual amino acids from particle size fractions and over depth provide insight into phytoplankton origins and microbial or zooplankton alteration of particulate matter involved in carbon export. Compound-specific isotopic data and amino acid quantities were collected using gas chromatography-isotope ratio mass spectrometry, and bulk isotopic data and quantities were collected using elemental analysis-isotope ratio mass spectrometry, both at University of Hawaii. Dr. Hilary Close (former affiliation: University of Hawaii, current affiliation: University of Miami) was the primary investigator involved in sampling and analysis of data presented here.";

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.
