"##Limitations:
Purpose: To monitor changes in physical, biological and geochemical properties of the Canadian Arctic waters, ocean observatories (moorings) were deployed in the Beaufort Sea, Hudson Bay, Lancaster Sound, and Melville Sound as part of the ArcticNet field program. These moorings are the oceanic equivalent of atmospheric meteorological stations. The data are used to describe the seasonal and annual variations in the Arctic environment and its local ecosystems. This, in turn, enables us to understand how, and how quickly, global warming is affecting the Arctic

    String summary 
"Thirty-six moorings were deployed in the Beaufort Sea between 2004 and 2010. Some of the moorings were deployed for one year only and others were maintained (recovered and redeployed) over several years. A total of 12 moorings were lost (1 in 2004, 2 in 2006, 1 in 2007, 2 in 2008, and 6 in 2010). Mooring sites included the Mackenzie Shelf (North-Western to North-Eastern), Mackenzie Shelf slope, Kugmallit Valley, Canada Basin, Mackenzie Canyon, Amundsen Gulf (West to East), and outer Franklin Bay area. Bottom depth at deployment sites varied between 200 and 545 m. Mooring lines were equipped with various oceanographic instruments attached at different depths from 12 m to a maximum of 500 m below the surface. Moored instruments included ALEC conductivity-temperature-turbidity- chlorophyll-PAR sensors, SeaBird SB 26 and SB37 conductivity-temperature sensors, RMC4, RMC7 and RCM11 current meters, Nortek current profilers, McLane moored profilers and NIPR and Technicap sediment traps. The datasets available were quality controlled, and have been used in several publications listed in the document accompanying the data. Variables available include water temperature, conductivity (salinity), density, PAR, Chla, turbidity, oxygen and current velocity (speed and direction). Sediment trap collections were used to estimate downward fluxes of particles, and datasets are described in Metadata CCIN 10476 (Vertical particle flux data in the Beaufort Sea: 2002-2010).
This dataset is a reprocessed version of the previous one. The processing chain used is built upon open-source Integrated Marine Observatory System (IMOS) toolbox developed for Matlab© by the Australian Ocean Data Network (AODN; Galibert, 2016).";

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 (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
