String summary "Non‑thermal factors such as nutrient availability and light can influence the alkenone unsaturation index, UK-37, and introduce uncertainty into sea‑surface temperature (SST) reconstructions based on this proxy. We investigated the effects of nutrient concentrations on alkenone unsaturation and UK-37‑derived temperatures in natural populations of alkenone‑producing haptophytes across the Chatham Rise, east of New Zealand. Water‑column samples were collected during three seasons from subtropical and subpolar sites representing contrasting low‑ and high‑nutrient regimes.";

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.
