Chief Scientist: Richard Limeburner
CHARLES ISELIN CRUISE 9407, CTD DATA QUALITY REVIEW
GENERAL COMMENT: THIS DATA SET IS OF POOR QUALITY, USE \"CAUTION\".
1..CAST SAMPLING INFORMATION EDITED TO BE CONSISTENT WITH THE EVENT LOG.
DATES AND TIMES ARE REPORTED AS GMT.
2..CASTS 96 AND 98 CONTAIN ONLY A SURFACE DATA CYCLE. FILES DELETED.
3..OXYGEN BAD ALL CASTS. REPLACED WITH -9..
4..SALINITY IS NOISY. SOME CASTS WORSE THEN OTHERS. NO ATTEMPT TO CLEAN UP.
USE WITH CAUTION.
5..LIGHT TRANSMISSION. CASTS 68 - 99 SHOW A ONE VOLT OFFSET FROM CASTS 1-68.
CALIBARATION PROBLEM? USE WITH CAUTION. NO ATTEMPT TO CLEAN UP SPIKES
6..FLUORESCENCE. CASTS 68 - 99 SHOW A TWO VOLT OFFSET FROM CASTS 1 - 68.
CALIBRATION PROBLEM? USE WITH CAUTION. NO ATTEMPT TO CLEAN UP SPIKES

String instruments_0_description "The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. 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.";

Developed in the 1970s, the Neil Brown CTD unit was able to digitize conductivity, temperature and pressure measurements at sufficient speeds to permit oceanographers to study 10 cm features at winch lowering speeds of 30 meters per minute. The most widely used variant in the 1980s and 1990s was the MK3B. The MK3C fitted with an improved pressure sensor to reduce hysteresis was developed to meet the requirements of the WOCE project. The instrument is no longer in production, but is supported (repair and calibration) by General Oceanics.";

"The U.S. GLOBEC Georges Bank Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, Haddock, and two species of zooplankton (Calanus finmarchicus and Pseudocalanus) - in terms of their coupling to the physical environment and in terms of their predators and prey. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.
The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).
Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.
The U.S. GLOBEC Georges Bank Executive Committee (EXCO) provides program leadership and effective communication with the funding agencies.";

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.
