TRIAXUS towed Seabird CTD data from the RISE Project, NODC accession 49910.
Sea-bird SBE 9 pumped CTD attached to the Triaxus towed undulating platform.

The purpose of the data collection was to provide transects through the Columbia River plum
to understand the distribution of water mass properties and configuration of isopycnal surfaces.
The data were also used in an analysis of Thorpe overturning scales to quantify vertical mixing
along the 50m isobath near the mouth of the Columbia River.

Because of the amount of data, they are presented as the complete (24Hz) dataset and a decimated
to 1 second dataset.  Both are large datasets.  The 2005 24Hz data are broken into two parts to allow
retrieval without the system timing out.
