Besides, 1 Savannah River water TA sample was measured. These samples were kept in 4 ° C walk-in refrigerator (if necessary) and were measured in 48 hours. TA samples were taken by 250ml narrow ground neck Pyrex bottles from Niskin bottles after removing air bubbles from the sampling tubing. Each glass bottle was rinsed three times using half of the bottle volume sample seawater and then filled from the bottom; overflow of half of bottle volume seawater was allowed. No headspace was left after the stopper was replaced. Duplicated sampling for one depth was done for every four stations.";

String detailed_sampling_and_analyzing_information "The SBE 43 dissolved oxygen sensor uses a membrane polarographic oxygen detector (MPOD). Oxygen sensors determine the dissolved oxygen concentration by counting the number of oxygen molecules per second (flux) that diffuse through a membrane. By knowing the flux of oxygen and the geometry of the diffusion path, the concentration of oxygen can be computed. The permeability of the membrane to oxygen is a function of temperature and ambient pressure. In order to minimize the errors in the oxygen measurement due the temperature differences between the water and the oxygen sensor, a temperature compensation is calculated using a temperature measured near the active surface of the sensor. The interface electronics output voltages proportional to the 13temperature-compensated oxygen current. Initial computation of dissolved oxygen in engineering units is done in the software. The range for dissolved oxygen is 120% of surface saturation in all natural waters, fresh and salt and the nominal accuracy is 2% of saturation.";

The draw temperature was taken using a digital thermometer with a flexible thermistor probe that was inserted into the flask while the sample was being drawn during the overflow period. These temperatures were used to calculate μmol kg -1 concentrations, and a diagnostic check of Niskin bottle integrity. One-ml of MnCl 2 and one-ml of NaOH/NaI were added immediately after drawing the sample was concluded using a Repipetor, the flasks were then stoppered and shaken well. DIW was added to the neck of each flask to create a water seal. The flasks were stored in the lab in plastic totes at room temperature for 1-2 hours before analysis. Twenty-four samples plus two duplicates were drawn from each station except the shallow costal stations where fewer samples were drawn depending on the depth.";

The major difference between the two systems is that Wanninkhof instrument uses a LI-COR© (model 6262) non-dispersive infrared analyzer, while the Chipman instrument utilizes a gas chromatograph with a flame ionization detector.";

Bottles were rinsed while inverted and filled from the bottom, overflowing half a volume while taking care not to entrain any bubbles. About 5 ml of water was withdrawn to allow for expansion of the water as it warms and to provide space for the stopper, tubing, and frit of the analytical system. Saturated mercuric chloride solution (0.2 ml) was added as a preservative. The sample bottles were 27sealed with a screw cap containing a polyethylene liner. The samples were stored in coolers at room temperature generally for no more than 6 hours.";

The cruise was designed to obtain a snapshot of concentrations and fluxes of key carbon, physical, and biogeochemical parameters in the coastal realm. The program is in support of the North American Carbon Program (NACP) that has as overriding goal to constrain fluxes of carbon over North America and adjacent seas. This project is in support of the North American Carbon Program (NACP) and represents a collaboration between the National Oceanic and Atmospheric Administration, the Earth System Research Laboratory, the University of Miami Rosenstiel School of Marine and Atmospheric Science, the University of South Florida, the University of Georgia,the University of New Hampshire, Texas AM University, the University of Colorado, the University of Southern Mississippi, Loyola College of Maryland, and Lamont Doherty Earth Observatory.

String updates_changes "Post-Cruise Updates/Changes: February 27, 2008 – Received Chris Fairall’s meteorology flux data. February 21, 2008 – Received Joe Salisbury’s DOC data from Robert Castle. The data is not yet merged into the data file. February 17, 2008 – Received the GOMECC buoy-deployed ADCP data report From Philip Orton. February 16, 2008 – Received Shari Yvon-Lewis’s HCFC underway data. March 14, 2008 – Heike reformatted the flux data and added a header line.March 22, 2008 – Merged Joe Salisbury’s bottle DOC data into the master datafile. Duplicates were averaged with a WOCE QC flag of 6. Sample number RB22 20070716 3-1 was missing the bottle number in UNH log file; this sample was not merged into the datafile. Posted the updated master data file along with the original DOC data on the GOMECC data page. March 23, 2008 – Posted the DOC underway data on the GOMECC data page. March 27, 2008 – Merged the bottom depths into the master datafile. April 24, 2008 – Per Xinping Hu’s request changed TALK for sample number 6801 from 2751.866944 to 2263.33227382272. June 27, 2008 – Robert Castle received and posted the CTD data on AOML ftp site: /ocd/pub/castle/GOMECC. October 31, 2008 – Received and posted Natchanon Amornthammarong’s underway ammonia data. November 4, 2008 – Received and posted Dr. Salisbury’s underway chlorophyll data. November 8, 2008 – Received and posted Dr. Byrne’s underway DIC data. December 4, 2008 – Received and merged the nutrient bottle update into the GOMECC Bottle data file. July 15, 2010 – Received and merged the final nutrient bottle data into the GOMECC Bottle data files GOMECCMasterBottle.xls and GOMECCMasterBottle.csv.";

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.
