"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.
 
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.
 
Discrete 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.
 
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.\\u00a0The in-
situ oxygen values were used to check, and when necessary calibrate, the CTD
oxygen profiles.
 
Discrete Chlorophyll  
 Continuous fluorescence profiles were obtained with a Sea Tech Fluorometer
coupled to the SBE-25 CTD. Discrete chlorophyll samples were immediately
filtered through 25 mm Whatman GF/F filters in triplicate and frozen. The
chlorophyll-a determination followed Holm-Hansen et al. (1965), and the
calculations were done as indicated in Lorenzen (1966). Among the
modifications are the use of methanol instead of acetone as an extraction
solvent due to its greater efficiency (Holm-Hansen and Riemann, 1978) and the
use of a sonic dismembrator (Wright et al., 1997). The method applies to all
ranges of chlorophyll-a concentration found in seawater. The method detection
limit is 0.01 \\u03bcg L-1 for natural waters (for a 0.5 L sample).
Fluorescence profiles were calibrated with in-situ chlorophyll-a and it is
presented in its native units of RFU (fluor_CTD) and also in micrograms/m^3
(fluor_chla).";

    String instruments_1_description "The Sea-Bird SBE 25 SEALOGGER CTD is battery powered and is typically used to record data in memory, eliminating the need for a large vessel, electrical sea cable, and on-board computer. All SBE 25s can also operate in real-time, transmitting data via an opto-isolated RS-232 serial port. Temperature and conductivity are measured by the SBE 3F Temperature sensor and SBE 4 Conductivity sensor (same as those used on the premium SBE 9plus CTD). The SBE 25 also includes the SBE 5P (plastic) or 5T (titanium) Submersible Pump and TC Duct. The pump-controlled, TC-ducted flow configuration significantly reduces salinity spiking caused by ship heave, and in calm waters allows slower descent rates for improved resolution of water column features. Pressure is measured by the modular SBE 29 Temperature Compensated Strain-Gauge Pressure sensor (available in eight depth ranges to suit the operating depth requirement). The SBE 25's modular design makes it easy to configure in the field for a wide range of auxiliary sensors, including optional dissolved oxygen (SBE 43), pH (SBE 18 or SBE 27), fluorescence, transmissivity, PAR, and optical backscatter sensors.

"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.

Monthly cruises were conducted to the CARIACO station (10.50\\u00b0 N, 64.67\\u00b0 W) onboard the R/V Hermano Gin\\u00e9s of the Fundaci\\u00f3n La Salle de Ciencias Naturales de Venezuela. 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. One CTD composite profile was created for each cruise by stitching together the sections of the different cruise's CTD profiles at the depth interval where water samples were obtained. CTD\\u2019s Salinity, Oxygen, and Fluorescence where calibrated with in-situ measurements. The composite CTD profiles dataset is a complement of the hydrographic time series data obtained with the Niskin Bottle Samples (https://www.bco-dmo.org/dataset/3093). The following sections describe the methods used in collecting the core observations at the CARIACO station.";

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.
