String summary
"Iron is an essential micronutrient for marine life, and its binding by organic binding ligands is one of the main drivers of its distribution across the world ocean. This dataset includes the concentration and conditional stability constant of dissolved iron-binding ligands in the samples collected during the U.S. GEOTRACES GP17-OCE cruise. The objective of the cruise was to investigate the distribution of trace metals and dependent variables in a vast region of the South Pacific and Southern Ocean. The cruise departed Tahiti (French Polynesia) on December 1, 2022, and arrived in Punta Arenas (Chile) on January 25, 2023, crossing the Western South Pacific gyre, the Pacific-Antarctic ridge, the Southern Pacific Ocean, and the Chilean margin. Seawater samples were collected using trace metal clean techniques and stored frozen (-20 degrees Celsius) until analysis by Dr. Léo Mahieu in Kristen Buck's Elemental Ocean Lab, Oregon State University.
The regions crossed during this transect represent a diversity of nutrient regimes, from oligotrophic to high nutrient-low chlorophyll systems, and deep waters were influenced by different hydrothermal systems, namely the East Pacific rise and the Pacific Antarctic ridge. This transect also crossed regions of intermediate and mode water mass formation, and the dynamic frontal system separating the warm South Pacific Ocean and the cold Southern Ocean. This cruise was a unique opportunity to investigate this vast and sparsely studied region, and our observations highlight potential processes leading to variations in iron-binding ligand characteristics along the water column across regions, fronts, nutrient regimes, hydrothermal influence, and water masses.";

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.
