String acquisition_description
"Nutrient Analysis Equipment and Techniques:
Nutrient samples were collected, filtered (0.2 \\u00b5m Acropak-200
polyethersulfone filters, Pall) and frozen on board until analysis on shore up
to 3 months later. Nutrient analyses (phosphate, silicate, nitrate+nitrite,
nitrite, ammonium, and urea) were performed on 6-channel Astoria-Pacific
autoanalyzer using standard methods (WHPO 1994). Ammonia analyses were based
on Solorzano (1969), using phenol/hypochlorite in alkaline medium with a
sodium nitroprusside catalyst. Urea analyses were based on Aminot and Kerouel
(1982) using diacetyl monoxime in acid solution.
Dissolved Oxygen Analysis Equipment and Techniques:
Samples were collected for dissolved oxygen analyses soon after the rosette
was brought on board. Using a Tygon or silicone drawing tube, nominal 125 ml
volume-calibrated iodine flasks were rinsed 3 times with minimal agitation,
then filled and allowed to overflow for at least 3 flask volumes. Reagents
(MnCl2 then NaI/NaOH) were added to fix the oxygen before stoppering. The
flasks were shaken twice (>1 minute inversions) to assure thorough dispersion
of the precipitate. The lip of the flask stopper was the filled with ultrapure
water to prevent access to atmospheric oxygen during the up to 3 hours between
sample collection and analysis.
Oxygen flask volumes were determined gravimetrically to determine flask
volumes at TAMU Geochemical and Environmental Research Group (GERG). This is
done once before using flasks for the first time and periodically thereafter
when a suspect volume is detected.
Dissolved oxygen analyses were performed with an automated Winkler oxygen
titrator (Langdon Enterprises, Miami) using amperometric end-point detection.
Thiosulfate (nominally 0.01 N) was standardized against 0.01 N potassium
iodate prior to sample analysis.
Salinity Analysis Equipment and Techniques:
Salinity samples were drawn into 200 mL Kimax high-alumina borosilicate
bottles, which were rinsed three times with sample prior to filling to the
shoulder. The bottles were sealed with plastic insert thimbles to reduce
evaporation. PSS78 salinity (UNESCO 1981) was calculated for each sample from
the measured conductivity ratios.\\u00a0
A Guildline Autosal 8400B salinometer (S/N 65715) was used for
salinity/conductivity measurements. The salinity analyses were performed after
samples had equilibrated to laboratory temperature, usually within 6 weeks
after collection. The salinometer was standardized for each group of analyses
using OSIL standard seawater, with frequent use of a secondary deep water
standard to check for drift during runs.\\u00a0";

String instruments_0_description
"The ADCP measures water currents with sound, using a principle of sound waves called the Doppler effect. A sound wave has a higher frequency, or pitch, when it moves to you than when it moves away. You hear the Doppler effect in action when a car speeds past with a characteristic building of sound that fades when the car passes.
The ADCP works by transmitting \"pings\" of sound at a constant frequency into the water. (The pings are so highly pitched that humans and even dolphins can't hear them.) As the sound waves travel, they ricochet off particles suspended in the moving water, and reflect back to the instrument. Due to the Doppler effect, sound waves bounced back from a particle moving away from the profiler have a slightly lowered frequency when they return. Particles moving toward the instrument send back higher frequency waves. The difference in frequency between the waves the profiler sends out and the waves it receives is called the Doppler shift. The instrument uses this shift to calculate how fast the particle and the water around it are moving.
Sound waves that hit particles far from the profiler take longer to come back than waves that strike close by. By measuring the time it takes for the waves to bounce back and the Doppler shift, the profiler can measure current speed at many different depths with each series of pings. (More from WHOI instruments listing).";

String instruments_5_description "A platinum-electrode conductivity sensor and a thermistor mounted in a corrosion-resistant plastic and titanium housing designed to be continuously plumbed into a vessel's pumped seawater supply. The instrument may be interfaced to a remote SBE 38 temperature sensor mounted either on the hull or in the seawater inlet. Data are both stored in internal memory and output to a serial port for external logging. Conductivity is measured in the range 0-7 S/m with an accuracy of 0.001 S/m and a resolution of 0.0001 S/m. Housing temperature is measured in the range -5-35C with an accuracy of 0.01 C and a resolution of 0.001 C. Remote temperature is measured in the range -5-35C with an accuracy of 0.001 C and a resolution of 0.0003 C. More information at http://www.seabird.com/products/spec_sheets/21data.htm.";

"NSF abstract:
A new Research Experiences for Undergraduates (REU) Site will be located at Texas A&M University's campus in College Station, TX. The Geochemical and Environmental Research Group (GERG) and the Department of Oceanography will host 10 REU students for 10 weeks each summer, and the program will focus on innovative ocean observing technologies. Students will have access to a suite of ocean data acquisition technologies incorporated in TAMU's offshore buoy system, glider technology, remote real-time measurements from moored instrumentation, shipboard field surveys with CTD profiling and water sampling. A group project to develop and deploy a glider mission in the Gulf of Mexico onboard a research vessel will promote team building. Training modules on sensors, data analysis, graphical representation of oceanographic data, data management, and science writing will be provided. Students will participate in weekly REU seminars, and at the program end, they will demonstrate their communication skills with a final written report and a seminar presentation at the GERG REU Student Research Symposium. Although the program is open to students who are US citizens or permanent residents attending any university, local recruitment efforts will be coordinated with faculty in the NSF-funded Alliance for Graduate Education and the Professoriate (AGEP) program which supports mentoring of STEM majors across TAMU branch campuses (Kingsville, Corpus Christi, Prairie View and West Texas).";

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.
