cruisetrack(cruise_name)

Construct GEOTRACES CruiseTrack from cruise name.

dictionary(ds)

A dictionary of the variables name and long_name attributes.

Useful for development, dictionary(ds) allows me to provide shortcuts — and a friendlier interface — for accessing GEOTRACES variables.

isotope(tracer)

Returns the GEOTRACES variable name of the isotope of tracer str.

list_of_cruises()

List of GEOTRACES cruises.

list_of_stations()

List of GEOTRACES stations.

matchingvariables(ds::Dataset, str::String)

Lists names of variables that have str in their long_name attribute.

metadata(tracer1, tracer2, tracer3, ...)

Returns the GEOTRACES metadata for given tracers.

observations(tracer1, tracer2, tracer3, ...)

Returns the GEOTRACES observations of the given tracers.

Example usage

x, y, z, ... = observations(tracer1, tracer2, tracer3, ...)
x = observations(tracer1)

Quality control flags

By default, only observations with quality control flag of 1 are kept. If you want more data, you must define keyword-argument QCmax.

x, y, z, ... = observations(tracer1, tracer2, tracer3, ...; QCmax = 2)
x = observations(tracer1; QCmax = 3)

qcvarname(tracer)

Returns the GEOTRACES variable name of the quality control of tracer str.

qualitycontrols(tracer1, tracer2, tracer3, ...)

Returns the GEOTRACES quality control flag of the given tracers.

GEOTRACES's Chars are converted to Int by this function.

From GEOTRACES:

1 = good quality
2 = not evaluated, not available or unknown quality
3 = questionable/suspect quality
4 = bad quality
9 = missing data

Note that there should be no 9 because missing data is skipped by the observations function.

stdvarname(tracer)

Returns the GEOTRACES variable name of the standard deviation of tracer str.

transect(tracer::String, cruise::String)

The Transect of observations of tracer tracer along cruise cruise.

transects(tracer::String, cruise::String)

The Transects of observations of tracer tracer.

varname(tracer)

Returns the GEOTRACES variable name that "matches" tracer.
