String acquisition_description
"## Sampling
Ocean time series samples are collected in standard 8L Niskin bottles. For
samples in and below the oxycline, a nitrogen line is attached to the upper
air vent to prevent air from entering the bottle during subsampling. Samples
for live analysis are first transferred without headspace to a 1L glass sample
bottle with Teflon standard taper stopper. In the ship's lab, subsamples are
transferred to 25 or 40 ml incubation vials, also under nitrogen. All vials
are filled from the bottom with overflow of about 3 vial volumes and then
sealed with no headspace.
Low molecular weight fatty acids: Volatile fatty acids are measured using the
technique developed by Yang (1991), Yang et al. (1993) and Wu and Scranton
(1994). Detection limits are about 1 (M for acetate). However, in some cases,
deep water values are lower than 1 micromolar for acetate in which case we
have estimated blanks in individual files. Samples are poisoned with 1 ml 10N
KOH per liter.
Fatty acid uptake rate constants: Acetate uptake rate constants are determined
using radiolabeled tracers as described by Wu and Scranton (1994). Incubations
are done anoxically in the dark in screw-top septum vials. Uptake includes
both conversion of isotope to CO2 (respiration) and to biomass which can be
filtered onto a 0.2 m Nuclepore filter (incorporation).
### CH4:
CH4 is assayed by gas chromatography using the vial equilibration technique of
Johnson et al. (1990) and a Carle 211AC gas chromatograph. Samples are
poisoned by addition of 10N KOH solution at a rate of 200 l per 50 ml vial.
### H2S:
Samples for sulfide analysis are taken in well-flushed glass syringes without
bubbles and are injected into vials containing Zn-acetate. Upon return to the
laboratory, the ZnS is dissolved and is analyzed spectrophotometrically by the
method of Cline (1969).
### Microbial census:
Abundances of remineralizers (bacteria) and regenerators (protozoa) are
determined using microscopic censuses. Preserved samples (2% formaldehyde) are
stained with a fluorochrome (DAPI or acridine orange) and captured on the
appropriate porosity Nuclepore membrane (0.2 or 0.8 m). Filter-retained cells
are enumerated and sized by epifluorescence microscopy according to Taylor et
al. (1986). Larger, less abundant protozoa are enumerated on settled samples
using inverted microscopy. Abundance and distribution of methanogens are
determined by an autofluorescence microscopic technique whereby the
fluorescence of coenzymes F420 and F350 in cells produced by two sets of
excitation and barrier filters is considered presumptive identification of
methanogens (Doddema and Vogels 1978).
### Bacterial production:
Bacterial incorporation is measured using 3H-leucine incorporation as
described by Kirchman (1993). Triplicate samples are incubated for 10-12 h in
gas-tight screw-top vials to minimized alteration of the redox potential. Time
course experiments have confirmed that uptake is linear for at least 15 hours.
Due to the fact that some important anaerobic bacteria appear to not take up
exogenous thymidine under anoxic conditions (McDonough et al. 1986; Gilmour et
al. 1990), the more common method of Fuhrman and Azam (1982) is inappropriate
for this system.";

"Since 1995, the CARIACO Ocean Time-Series (formerly known as the CArbon Retention In A Colored Ocean) Program has studied the relationship between surface primary production, physical forcing variables like the wind, and the settling flux of particulate carbon in the Cariaco Basin. This depression, located on the continental shelf of Venezuela (Map), shows marked seasonal and interannual variation in hydrographic properties and primary production (carbon fixation rates by photosynthesis of planktonic algae).
This peculiar basin is anoxic below ~250 m, due its restricted circulation and high primary production (Muller-Karger et al., 2001). CARIACO observations show annual primary production rates exceed 500 gC/m2y, of which over 15-20% can be accounted for by events lasting one month or less. Such events are observed in other locations where time series observations are collected, and suggest that prior estimates of regional production based on limited sampling may have been underestimated. The annual primary production rates in the Cariaco Basin are comparable to rates estimated using time series observations for Monterey Bay (460 gC/m2y; Chavez, 1996), and higher than previous rates estimated for Georges Bank, the New York Shelf, and the Oregon Shelf (380, 300, and 190 gC/m2y, respectively; Walsh, 1988).
The Cariaco Basin has long been the center of attention of scientists trying to explain paleoclimate. Due to its high rates of sedimentation (30 to >100 cm/ky; Peterson et al., 2000) and excellent preservation, the varved sediments of the Cariaco Basin offer the opportunity to study high resolution paleoclimate and better understand the role of the tropics in global climate change ( Black et al., 1999; Peterson et al., 2000; Haug et al., 2001; Black et al., 2004; Hughen et al., 2004 ).
Now, the CARIACO program provides a link between the sediment record and processes near the surface of the ocean. Sediment traps maintained by the CARIACO program show that over 5% of autochtonous material reaches 275 m depth, and that nearly 2% reaches 1,400 m. The significance of this flux is that it represents a sink for carbon and that it helps explain the record of ancient climate stored at the bottom of the Cariaco Basin.

String summary "Biogeochemistry and microbiology measurements in the Cariaco Basin. Microbiology sampling were conducted during special CARIACO cruises (distinct from the monthly, core sampling, time-series cruises) from November 1995 to November 2015. The specialized microbiology cruises were usually during May and November, and could be opportunistic or process-driven. There were typically at least 2 cruises per year, during which different variables were sampled and at different depths from the standard monthly CARIACO cruises. Bacteria production data were also reported for the microbiology cruises.";

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.
