Vitiaz Strait Transport (PCM15)

This experiment produced 35 current meter records from 5 moorings, each of which was occupied twice. You can view metadata and download the records by clicking on links in the table below. A brief description of the experiment also is available. Each current meter record is identified in the table by its depth and the name of the mooring. You may want to look at a map of the array first to see where the moorings were. If you download any of the current meter records you should review the note on file format. From here you can also move up one level to the list of WOCE experiments.

Note that each of the 5 moorings was occupied twice - Phases 1 and 2. In some cases the Phase 1 and Phase 2 current records are nearly (but not quite) contiguous. In others the gap between the two deployments is significant.

Description of WOCE component PCM15

Vitiaz Strait acts as a choke point for a western boundary current that carries water equatorward along the northeastern coast of New Guinea. This is a significant current, with transports that sometimes approach 20 sv. The present experiment was designed to extend the spatial and temporal resolution of earlier measurements in the strait that established the existence and strength of this current.

PCM15 went forward in two phases. The first phase began in February 1992; Aanderaa and Endeco current meters were installed on 5 moorings spanning the Vitiaz Strait (see map). This produced 14 useful current records of varying lengths. During the second phase, which began in July 1992, the moorings were revisited and replaced. The second set of instruments was recovered during April 1993, and produced 21 useful current records.

Some results of an analysis of the data can be found in

Format of the current records

These files have been compressed with the ZIP compression utility. After downloading them, you will need to expand them. WinZip or Pkzip will do the job on a PC that is running Microsoft Windows. Under Linux, gunzip will expand these files. Other utilities are available for the UNIX and Macintosh environments (for example, unzip and/or gunzip are present on most UNIX systems). After expansion, you will have binary files in the netCDF format.

netCDF is a self-documenting format that can be accessed by a variety of software tools. You can click here to learn about netCDF and available software packages that can be used to read and manipulate netCDF files.
