"Dissolved inorganic nutrient samples were pre-filtered through 0.45-\\u03bcm
polycarbonate syringe filters, kept refrigerated, and analyzed onboard the
ship within 1 day of sampling. Nitrate (NO3\\u2212), nitrite (NO2\\u2212), am-
monium (NH4+), phosphate (HPO42\\u2212), and silicic acid (Si(OH)4) were
measured using a five-channel Lachat Instruments QuikChem FIA+ 8000s series
autoanalyzer in conjunction with a Lachat Instruments XYZ AutoSampler (ASX-500
Series), two Lachat Instruments RP-100 Series peristaltic Reagent Pumps, and
Omnion Software, version 3.0.220.02.\\u00a0
 
Seawater samples were analyzed for dissolved Fe over the period of January to
August 2012, using an automated flow injection ICP-MS method developed at
Rutgers University (Lagerstr\\u00f6m et al., 2013). Briefly, the automated
device loaded a 9 mL aliquot of seawater, buffered online to pH 7.0 with 3 mL
of acetic acid/ammonium hydroxide buffer, onto a column packed with Nobias PA1
chelating resin (Hitachi High-Technologies). The column was eluted with 1.5 M
nitric acid directly into the nebulizer of an Element-1 sector field ICP-MS
(Thermo-Finnigan, Bremen, Germany). The eluate, a 200-fold concentrate of the
sample, was analyzed in medium resolution and temporal peak integration was
performed in Matlab using a script written in-house. Quantification was
carried out using isotope dilution (Fe, Ni, Cu and Zn) or a matrix-matched
external standard curve (Mn).\\u00a0
 
Samples for particulate organic carbon (POC) and nitrogen (PN) were collected
by cleanly filtering 100\\u2013600 mL of seawater onto a 25-mm diameter,
combusted GF/F filter (nominal pore size of 0.7 \\u03bcm) which was then folded
sample side in and frozen at \\u221280\\u00b0C. Samples were processed at
Rutgers University and analyzed using a Carlo-Erba CHN analyzer (Hedges and
Stern, 1984).\\u00a0
 
Water column Chl a concentration (used as a proxy for algal biomass) was
measured onboard ship using acetone extraction and a spectrofluorometer
(Alderkamp et al., 2015). Shipboard values were calibrated against a second
set of samples collected similarly, flash-frozen in liquid N2, stored at
\\u221280\\u00b0C, and analyzed at Mote Marine Lab using HPLC (Wright et al.,
1991; see Alderkamp et al., 2015).";

"The Amundsen Sea, in the remote Pacific sector of the Southern Ocean, is one of the least well studied Antarctic continental shelf regions. It shares characteristics in common with other Antarctic ice shelf regions, but exhibits unique aspects also. The Amundsen Sea Polynya (ASP), an open region at the base of several of the terminal glaciers draining the West Antarctic Ice sheet exhibits: 1) large intrusions of heat delivered from the warming modified circumpolar deep water (mCDW) rising up onto the continental shelf, 2) the fastest melting ice sheets in Antarctica, 3) the most productive coastal polynya (161 g C m-2) together with a significant atmospheric CO2 sink, and 4) some of the most rapidly declining regions of seasonal off-shore sea ice on Earth.
Following on from an earlier oceanographic field program, the Amundsen Sea Polynya International Research Expedition (ASPIRE; 2011), this study seeks to better synthesize and model the relative contributions of both physical ocean-ice linkages and biological production and carbon export terms and to compare these with other circumpolar Antarctic regions. A central feature will be the use of a regionally coupled physical-biogeochemical model to follow the dynamics of the large phytoplankton blooms that occur annually in the Amundsen Sea Polyna. This study will provides a means to locate the Amundsen Sea properties along the continuum of Antarctic ice shelf systems, and to understand how these system might change in response to climate change.
Pedagogical techniques will be used to provide educational outreach for three distinct target populations: secondary students, pre-service science teachers, and in-service science teachers. Partnerships will be developed with science teacher educators to implement the STEM career-development lessons in undergraduate and graduate level science teacher education courses.";

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.
