This dataset contains auxiliary, preliminary, and other datasets
that are in preparation to be included in a future ICOADS release.
Data are provided either in IMMA1 or native (non-IMMA1) format. It
also contains datasets in IMMA1 and non-IMMA1 formats that have
transitioned into ICOADS. This dataset was created in 2018 in
conjunction with the completion of Release 3.0 and efforts going
forward - it is not a complete collection of inputs for ICOADS
beginning with Release 1. The purpose of this dataset is to provide
a common archive point for data exchange with ICOADS researchers and
track the provenance as input data sources are added to official
releases. These sources are not recommended for general public use.
If source data are archived in a different independent RDA dataset,
those data are not duplicated in this dataset, but will be
referenced with a "Related RDA Dataset" link, e.g. DS285.0 is the
World Ocean Database in a non-IMMA1 format provided by NCEI.
