String summary "This dataset includes lead-210 activity data of short sediment cores of submarine canyon slopes sampled from October 2020 to Oct 2022 offshore Pointe-des-Monts. The objective of this work is to determine the recurrence of turbidites observed in the short sediment cores in order to determine if they reflect turbidity current activity within the Pointe-des-Monts submarine canyon system. The second objective is to determine the influence of bottom currents on the sedimentary deposits record. This project was originally funded by Réseau Québec maritime (RQM) and Marine Environmental Observation, Prediction, and Response Network (MEOPAR).";

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.
