String acquisition_description
"Rates of primary production were assessed using the 14C-bicarbonate
incorporation technique. Rates of bacterial production were assessed using
incorporation of 3H-leucine. Whole seawater samples from six discrete depths
(5, 25, 45, 75, 100, and 125 m) were collected into duplicate acid-washed 20 L
carboys. Control carboys were unamended; 43 mL of 1.0 N HCl and 4 mmol sodium
bicarbonate were added to a treatment carboy at each depth, to increase the
pCO2 to ~750 \\u00b5atm, while minimizing changes to total alkalinity. Water
from control and treatment carboys were then each subsampled into acid washed
500 mL polycarbonate bottles, with triplicate bottles per depth and treatment.
To each bottle, was then added ~1.85 MBq 14C-bicarbonate. Water from each
depth and treatment was also added to acid-cleaned 40 mL polycarbonate
centrifuge tubes, each tube was then inoculated with 3H-leucine to a final
concentration of 20 nmol L-1. For each depth and treatment, there was a dark
(in a opaque cloth bag) and light incubation. Time zero blanks were
immediately subsampled from each tube, by aliquoting 1.5 mL of seawater into 2
mL microcentrifuge tubes each containing 100 \\u00b5L of 100% TCA. Following
addition of radioactive substrates, the bottles and tubes were affixed to a
free-drifting array and incubated\\u00a0in situ\\u00a0at the original depth of
sample collection from dawn to dusk.
Upon recovery of the array, the total radioactivity added to each primary
production sample bottle was determined by subsampling 250 \\u00b5L aliquots of
seawater into scintillation vials containing 500 \\u00b5L of
\\u03b2-phenylethylamine. 400 mL from each 500 mL sample bottle was filtered at
low vacuum (<50 mm Hg) onto 25 mm diameter, 10 \\u00b5m porosity polycarbonate
membrane filters. The filtrate was collected and filtered onto 25 mm diameter
2 \\u00b5m porosity polycarbonate membrane filters. 100 mL of that filtrate was
then filtered onto 25 mm diameter 0.2 \\u00b5m porosity polycarbonate membrane
filters.\\u00a0 Filters were stored frozen in 20 mL scintillation vials until
analysis. Analysis consisted of acidification via addition of 1 mL of 2 N
hydrochloric acid, and passively venting at least 24 hours in a fume hood to
remove all inorganic 14C. Addition of 10 mL Ultima Gold LLT liquid
scintillation cocktail and counting on a Perkin Elmer 2600 liquid
scintillation counter completed the primary production analysis.
Upon recovery of the array, triplicate 1.5 mL subsamples were removed from
each polycarbonate tube for bacterial production rate measurements, and
aliquoted into 2 mL microcentrifuge tubes containing 100 \\u00b5L of 100% TCA.
The microcentrifuge tubes were frozen (-20\\u00b0C) for subsequent processing,
following the procedures described in Smith and Azam 1992.
Samples for the determination of dissolved inorganic carbon and total
alkalinity were collected from each carboy and analyzed according to the
protocols of the Hawaii Ocean Time-series (Dore et al. 2009; Winn et al.
1998). DIC and TA samples were collected into precombusted 300 mL borosilicate
bottles. Care was taken to avoid introduction of air bubbles into samples
during filling; bottles were allowed to overflow three times during filling.
Once filled, samples were immediately fixed with 100 \\u00b5L of a saturated
solution of mercuric chloride; bottles were capped with a grease seal, and
stored in the dark for later analysis.
Samples for measurement of fluorometric chlorophyll\\u00a0a\\u00a0were collected
according to the protocols of the Hawaii Ocean Time-series; analysis was
performed following Letelier et al. (1996).";

The instrument is lowered via cable through the water column and permits scientists observe the physical properties in real time via a conducting cable connecting the CTD to a deck unit and computer on the ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast. This instrument designation is used when specific make and model are not known.";

String instruments_1_description "Liquid scintillation counting is an analytical technique which is defined by the incorporation of the radiolabeled analyte into uniform distribution with a liquid chemical medium capable of converting the kinetic energy of nuclear emissions into light energy. Although the liquid scintillation counter is a sophisticated laboratory counting system used the quantify the activity of particulate emitting (ß and a) radioactive samples, it can also detect the auger electrons emitted from 51Cr and 125I samples.";

String projects_0_description
"The North Pacific Subtropical Gyre (NPSG) is the largest ocean ecosystem on Earth, playing a prominent role in global carbon cycling and forming an important reservoir of marine biodiversity. Nitrogen (N2) fixing bacteria (termed diazotrophs) provide a major source of new nitrogen to the oligotrophic waters of the NPSG, thereby exerting direct control on the carbon cycle. Oceanic uptake of CO2 causes long-term changes in the partial pressure of CO2 (pCO2) in the seawater of this ecosystem. Therefore, understanding how carbon system perturbations may influence ocean biogeochemistry is an important and timely undertaking.
In this project, the investigators will examine how natural assemblages of N2 fixing microorganisms respond to perturbations in seawater carbon chemistry. Laboratory and field-based experiments will be placed in the context of monthly time series measurements on the activities and abundances of N2 fixing microorganism abundances. Together, the project will provide insight into the dependence of N2 fixing microorganism physiology on variations in CO2. The broad objectives of the research are: (1) Quantify the responses and consequences of changes in seawater pCO2 on the growth and community structure of naturally-occurring assemblages of ocean diazotrophs; (2) Identify why and how changes in seawater pCO2 influence the growth and carbon acquisition strategies of two model marine diazotrophs (Trichodesmium and Crocosphaera); and (3) Quantify temporal variability in diazotroph community structure and activities at Station ALOHA.
This is a Collaborative Research award.";

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.
