"Hydrocasts: CTD and Rosette Sample
 
During each cruise, a minimum of four hydrocasts were performed to collect a
suite of core monthly observations. Additional hydrocasts were performed for
specific process studies. We conducted separate shallow and deep casts to
obtain better vertical resolution for chemical observations, and for
productivity and pigment observations. Water was collected with a SeaBird
rosette equipped with 12 (8 liter) teflon-coated Niskin bottles (bottle
springs were also teflon-coated) at 20 depths between the surface and 1310 m.
The rosette housed the CTD, which collected continuous profiles of temperature
and salinity. The CTD also had a SBE-43 oxygen probe, a Wetlabs ECO
fluorometer outfitted for chlorophyll-a estimates, and a C-Star
transmissometer (660 nm, Wetlabs). Beam attenuation measurements were added to
the time series on its 11th cruise (November 1986) originally using a SeaTech
transmissometer. The rosette was controlled with a SeaBird deck unit via
conducting cable, but alternatively it had been actuated automatically based
on pressure recordings via an Autofire Module (SBE AFM) when breaks in cable
conductivity had occurred.
 
 Between November 1995 and September 1996, three separate SBE-19 CTDs were
used in repeated casts until a reliable salinity profile was obtained below
the oxycline. The SBE-19 model CTDs frequently failed to provide reliable
conductivity values below the oxycline in the Cariaco Basin. Starting in
September 1996, the SBE-19 CTDs were replaced by SBE-25 CTDs, which provided
extremely accurate and reliable data in anoxic waters.  
 \\u00a0
 
All CTDs were calibrated at the Sea-Bird factory once per year. The accuracy
of the pressure sensor was 3.5 m and had a resolution of 0.7 m. The
temperatures accuracy was 0.002\\u00b0C with a resolution of 0.0003\\u00b0C. The
conductivity accuracy was 0.003 mmho/cm with a resolution of 0.0004 mmho/cm.  
 \\u00a0
 
Salinity
 
Continuous salinity profiles were calculated from the CTD measurements.
Discrete salinity samples were analyzed using a Guildline Portasal 8410
salinometer standardized with IAPSO Standard Seawater, with a precision of
better than \\u00b1 0.003 and a resolution of 0.0003 mS/cm at 15\\u00b0 C and 35
psu, the accuracy was \\u00b10.003 at the same set point temperature as
standardization and within -2\\u00b0 and +4\\u00b0C of ambient. These salinity
values were used to check, and when necessary calibrate, the CTD salinity
profiles.  
 \\u00a0
 
Discrete Oxygen
 
Continuous dissolved oxygen (O2) profiles were obtained with a SBE-43
Dissolved Oxygen Sensor coupled to the SBE-25 CTD. Discrete oxygen samples
were collected in duplicate using glass-stoppered bottles and analyzed by
Winkler titration (Strickland and Parsons, 1972, as modified by Aminot, 1983).
The analytical precision for discrete oxygen analysis was \\u00b13 mM, based on
analysis of duplicate samples, with a detection limit of 5 mM.  
 \\u00a0
 
Nutrients
 
Since CAR-072 (November 2001) all samples had been filtered through a 0.8
\\u00b5m Nucleopore filter within minutes of collection, as recommended by the
JGOFS protocol, and frozen in plastic bottles until analysis at the University
of South Florida (USF). Previous to November 2001, nutrients were filtered
through a 0.7 \\u00b5m GF/F filter before freezing. This data was still
considered reliable, as tests using glass fiber filters show no significant
contamination. The analyses follow the standard techniques described by
Strickland and Parsons (1972). USF follows the recommendations of Gordon et
al. (1993) for the WOCE WHP project for nutrient analysis.  
 \\u00a0
 
Since CAR-069 (August 2001) all silica samples were kept unfrozen; they were
refrigerated and kept in the dark. Prior to CAR-069, silicates were frozen and
those exhibiting high concentration of silica (> 40\\u00b5M below 300m in
CARIACO) were affected by polymerization. All deep samples that were frozen
showed low values due to polymerization loss, except CAR-063 and CAR-068 which
showed high values. CAR-069 was analyzed by Yrene Astor at EDIMAR from the
separate unfrozen bottlesand at USF from other, frozen, bottles. Unfrozen
CAR-069 resulted higher with deep values close to what was expected (e.g.
\\u223c92\\u00b5M at 1310m).  
 \\u00a0
 
Detection limits for CARIACO nutrient analysis
 
The limits below were determined by calculating the concentrations in
triplicate standards, averaging the results within each triplicate group,
calculating the standard deviation for each group, averaging the standard
deviations, and finally doubling the averages to get the detection limits.
These samples were analyzed on an ALPKEM RFA II. Subsequent Cariaco analyses
were performed on a Technicon Analyzer II

Primary Production
 
Primary productivity measurements were made using a modified Steeman Nielsen
(1952) NaH14CO3 uptake assay. The productivity measurements consisted of in
situ incubations of water collected at 8 depths and inoculated with 14C-
labeled bicarbonate. One hour before sunrise, a shallow cast was performed to
obtain water from 1, 7, 15, 25, 35, 55, 75, and 100 meters. As the
productivity cast was taken, a Licor Photosynthetically-Active Radiation (PAR)
integrator, placed high above the ship's bridge, was activated. Water was
poured directly from the Niskin bottle under low light conditions into 250 ml
clear polycarbonate bottles. These bottles had been previously acid-washed,
rinsed, and soaked in de-ionized water for over 48 hours. Bottles were rinsed
three times before filling, a near total fill (the volume within the bottles
was actually 290 ml of sea water). Four clear polycarbonate bottles were
filled from each depth. We wrap one inoculated bottle from each depth in
aluminum foil to obtain the dark 14-C uptake rates. An extra bottle for 1, 15,
35, and 75 m was filled, but not inoculated, to provide time-zero (t0) filter
and seawater blanks. The t0 samples were kept in the dark in the laboratory
and were filtered after deploying the floating incubation buoy.  
 \\u00a0
 
We inoculated each sample under low light conditions with 1,000 ml (4 mCi) of
the 14C sodium bicarbonate working solution. A 200 ml aliquot for counting
total added 14C activity was removed from one of the 3 bottles from each depth
and placed in a 20 ml glass scintillation vial containing 250 ml ethanolamine.
The mixture was held at 5\\u00b0C until subsequent liquid scintillation
analysis on shore. We also placed 50 ml of the 14C working solution in a vial
with ethanolamine (250 ml) for reference counting.  
 \\u00a0
 
The dark bottle and 3 light bottles were hooked together with a combination of
plastic tie wraps and nylon cord, and kept in the dark while preparations were
made for deployment of the productivity incubation float. At approximately
07:00 hours, the productivity array was deployed. The entire productivity
ensemble was attached to a buoy equipped with a flag and radar reflector.  
 \\u00a0
 
Productivity observations were initiated on December 1995. Between December
1995 and November 1996, we incubated samples from 06:00 to 10:00 hours.
Starting December 1996, we changed our protocol to incubate between 07:00 and
11:00 hours. This more accurately represents 1/3 of the daily photoperiod and
1/3 of the total energy received in one day on a year-round basis at
10\\u00b030'N, as verified with the PAR light sensor.  
 \\u00a0
 
Approximately 4 hours after deployment, the productivity array was recovered.
We decided to use 4-hour incubation periods due to the potentially high
productivity (>1,000 mg/(m\\u00b2d)) of this continental margin. Sample bottles
were detached from the line and placed in labeled, dark plastic bags until
filtration. Time and position of recovery were recorded. Maintaining low light
conditions, a 50 ml aliquot was withdrawn from each productivity bottle using
a 50 ml plastic syringe. This aliquot was filtered onto a 25 mm Whatman GF/F
glass fiber filter, maintaining vacuum levels of \\u223c1/3 atm. The filter was
rinsed with 0.25 ml 0.5 N HCl, and placed in a 20 ml glass scintillation vial,
covered, and held at 5\\u00b0C until subsequent processing on shore. At the
shore laboratory, immediately upon return and within 15 hours of sample
collection, 10 ml of liquid scintillation cocktail were added to the vials
with the filters. These vials were refrigerated until they were ready for
analysis on a BetaScout (PerkinElmer)scintillation counter.  
 \\u00a0
 
Carbon uptake calculations followed the standard formulation outlined in the
JGOFS manual (UNESCO, 1994), taking into consideration a (very low) quenching
curve. Specifically, we subtracted the blank from all bottles, and then
subtracted the dark bottle uptake from the average uptake in the light bottles
to correct for non-photoautotrophic carbon fixation or absorption. Dark uptake
values had always been very low. A scaling factor (\\u223c3) was applied to
convert the hourly production value to a \\\"daily mean hourly average\\\". This
factor varies slightly, as it was based on the fraction of the energy received
during the incubation period relative to the total energy received in a day.
Daily rates were derived by multiplying the hourly rate by 12. Gieskes and Van
Bennekom (1973), Peterson (1980), and Carpenter and Lively (1980) review the
historical background, problems, and assumptions involved in the application
of the radiocarbon technique to aquatic productivity. Muller-Karger (1984)
also summarizes the technique and corrections involved.  
 \\u00a0
 
pH and Alkalinity
 
pH samples were collected directly in 10-cm cells and analyzed on board. We
measured pH and total Alkalinity estimates using the precise
spectrophotometric dye methods developed by Robert-Baldo et al. (1985), Byrne
and Breland (1989), and which we modified from Clayton and Byrne (1993) and
Breland and Byrne (1993). These methods circumvent the problem that arises
when potentiometric electrodes were transferred from dilute buffers to sea
water samples due to the sample's high ionic strength. All the pH values were
reported in the Master file for CARIACO data at 25 \\u2103 to avoid the effects
of temperature on the solution chemistry. Measurement analytical precision for
pHT at 25\\u00b0C (total_hydrogen_ion_scale) = \\u00b10.003, and for
Total_alkalinity (mmol/kg), the precision is = 5 mmol/kg.\\u00a0  
 \\u00a0
 
Corrections of pH for dye indicator impurities: The pH method uses the dye
meta-cresol purple (mCP) as the pH indicator. The mCP dye used in CARIACO was
in its unpurified form. Impurities in the indicator dye may cause uncertainty
in measured pH values (Yao et al., 2007). Unpurified forms of the dye absorb
significantly at the wavelength of maximum absorption for the acid species,
HI- (434 nm) (Liu et al., 2011). The ratio of indicator absorbance at
wavelengths 578 (base specie, I2-) and 434 (R = A578/A434) is used to
calculate pH. Therefore, the effect of the impurities translates into apparent
lower pH calculated values, especially at surface waters where pH > 8.0 (Yao
et al., 2007). The effect of the impurities varies from one indicator
manufacturer to another, and from different batches of the same manufacturer
(Yao et al., 2007). Fortunately, the indicator used for the whole dataset in
CARIACO came from the same batch. Hence, a correction for mCP impurities was
applied following the method developed by Douglas and Byrne (2017) to each set
of data for each cruise. This correction translated to ~ -0.01 units at pH ~
8.1, decreasing to ~ - 0.008 units at pH ~ 7.6. The corrections were applied
to the whole dataset, and values for DIC and fCO2 were recalculated in the
Master file. All the pH values were reported in the Master file for CARIACO
data at 25 \\u2103 to avoid the effects of temperature on the solution
chemistry.\\u00a0  
 \\u00a0
 
Chlorophyll
 
Chlorophyll sample collection and storage: water samples were collected from
Niskin bottles into 1 L dark polyethylene bottles. These samples were
immediately filtered through 25 mm Whatman GF/F filters using a vacuum of less
than 100 mm Hg. During the upwelling season (approx. January-May) we filtered
250 ml seawater, and during the rest of the year we filtered 500 ml. Three
replicates were taken per depth during the upwelling season, but only two were
collected when biomass was obviously at its minimum, during the non-upwelling
season. Filters were folded in half twice and placed in glass centrifuge
tubes, labeled and frozen. Storage time was kept as short as possible (less
than a week) before measurement.  
 \\u00a0
 
Chlorophyll procedure: after removal from the freezer, the filters were
extracted in 10 ml of methanol. The samples were allowed to extract for 24
hours in the refrigerator. Following extraction, samples were centrifuged for
20 minutes to remove debris. The fluorometer (Turner fluorometer model
10-AU-005) was allowed to warm up and stabilize for 30 minutes prior to use.
Pure methanol was measured to confirm the zero position. Samples were
transferred to 1-cm cells and they were measured directly into the fluorometer
(Fo). 100 \\u00b5l of 0.48N HCl was added to each cell. A second reading was
taken from the fluorometer for each cell (Fa). Standardization. The
fluorometer was calibrated every year with a commercially available
chlorophyll a standard (\\u03a3). The concentration of chlorophyll-an and
phaeopigments in the sample were calculated using Yentsh and Menzel (1963)
equation, with a specific absorption coefficient of 74.5 (chlorophyll in
methanol).

HPLC
 
HPLC analysis was restarted in July 2006 (CAR-123). Samples were filtered 47
mm Whatman GF/F filters at 8 depths (1, 7, 15, 25, 35, 55, 75 and 100m). The
volume filtered depends on the amount of particles in the water. Replicates
were taken at the 1m depth. Filters were stored in aluminum envelopes and
stored in the fridge until reaching shore. Once on shore, samples were stored
at -40\\u00b0C until transportation to the US. Horn Point Laboratory
([http://www.hpl.umces.edu/](\\\\\"http://www.hpl.umces.edu/\\\\\")) performs the
analyses through a collaborative agreement with NASA. The method used was Van
Heukelem and Thomas (2001).\\u00a0  
 \\u00a0
 
POC and PON
 
POC and PON sample collection and storage: water samples were collected from
Niskin bottles into 2 L dark polyethylene bottles. These samples were
immediately filtered through 25 mm Whatman GF/F filters (precombusted for 5
hours at 450\\u00b0C) using a vacuum of less than 100 mm Hg. Since July 2007
(CAR-135) filters were acidified (10% HCl) after combustion and prior to
sample collection. A portion of these filters was used for POP analysis (see
below). Filters were placed on expendable tin disks and then into aluminum
foil envelops (also precombusted for 5 hours at 450\\u00b0C) labeled and
frozen. In the laboratory, filters were dried at 65\\u00b0C for 12-15 hours
then stored with silica gel.
 
Measurement: The filters were folded inside a tin disk and analyzed on a
Perkin Elmer 2400 Elemental Analyzer. The samples were combusted at
1200-1300\\u00b0C and then passed through a reduction tube to removes the
oxygen added to raise the combustion temperature. Filers were not acid fumed
prior to analysis. The C and N were then separated in a chromatographic column
and were measured on a Thermal Conductivity Detector. Carbon and nitrogen
standards, and blank filters were used to calibrate the data. The accuracy of
the instrument was <0.3% and the precision of the instrument was <0.2%. These
were published values and we find that we were always within these limits
(usually \\u00b10.15% for carbon and \\u00b10.1% for nitrogen). We ran cystine
as our standard (29.99% Carbon, 11.66% Nitrogen). The analytical range of the
instrument is: Carbon= .001 to 3.6 mg and Nitrogen= 0.001 to 6.0 mg.  
 \\u00a0
 
POP
 
POP was analyzed from the same POC/PON filters. The method used for the SRP
analysis was based on Koroleff (1983).  
 \\u00a0
 
Dissolved organic Carbon, Nitrogen and Phosphorous (DOC, DON and DOP)
 
Measurements of DOC were taken since the beginning of the project in November
1995 but suspended in February 2001 (CAR-062) due to irregularity of results.
DOC was reinitiated in March 2005 (CAR-110) using a new protocol. DOC samples
were collected monthly and analyzed at the Organic Biogeochemistry Lab in the
Rosenstiel School of Marine & Atmospheric Science at the University of Miami.
Samples were gravity-filtered directly from the Niskin bottles through 45 mm
GF/F precombusted filters using acid cleaned polycarbonate in-line filter
holder. Immediately after filtration the polyethylene bottles were frozen at
-20\\u00b0C until analysis.  
 \\u00a0
 
DON and DOP measurements were added to the regular CARIACO cruises in July
2004 (CAR-101). Samples were filtered through GF/F filters using a specially
built vacuum filter rack. The DON method was based on Solorzano and Sharp
(1980). This procedure produces a filtered seawater sample for analysis of
total dissolved fixed nitrogen (=nitrate + nitrite + ammonium + DON). DON
concentration was obtained by difference from nitrate, nitrite, and ammonium
measured in the standard nutrient protocol. DOP was analyzed in the same
persulfate-oxidized filtrate solution as DON. That solution yields total
inorganic phosphate concentration, which was composed of the inorganic
phosphate concentration originally in the seawater, plus an additional
phosphate concentration due to the conversion of DOP to phosphate. DOP
concentration was then obtained by difference from the inorganic phosphate in
the unoxidized sample measured through the standard nutrient protocol.
 
\\u00a0
 
Optical measurements
 
In-water measurements: a PRR-600 (Biospherical) was used to retrieve
downwelling irradiance and upwelling radiance. From these, PAR, Kd and
reflectance can be calculated. Beam attenuation coefficient (Cp) was measured
using a C-Star transmissometer (see section Hydrocasts: CTD and Rosette
Sample), which provides measurements at 660 nm throughout the entire water
column.  
 \\u00a0
 
CDOM samples were measured at four depths (1m, 15m, 25m, 50m) by filtration
through a 0.2 \\u00b5m pore size filter and immediately frozen at -20\\u00b0C.
Before being analyzed, they were thawed and re-filtered to eliminate any salt
crystals that may had formed. CDOM was measured between 200 and 800 nm, with a
0.3 nm interval, using a dual fiber optic spectrometer (Ocean Optics) equipped
with 10-cm quartz cuvettes and distilled water as a blank.  
 \\u00a0
 
Above water measurements: a PR-650 (Photoresearch) measures sky radiance (Ls),
water leaving radiance (Lw) and total irradiance (Es) at an angle of 30\\u00b0.
From these measurements, remote sensing reflectance (Rrs = Lw/Es) can be
calculated and used in satellite sensor (such as MODIS and SeaWiFS)
calibration.

"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.

During each cruise, a minimum of four hydrocasts were performed to collect a suite of core monthly observations. We conducted separate shallow and deep casts to obtain a better vertical resolution of in-situ Niskin-bottles samples for chemical observations, and for productivity, phytoplankton, and pigment observations.";

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.
