Kuroshio Regional Extension Experiment - KERE (PCM7)

This experiment produced 21 current meter records from 8 moorings (4 moorings occupied twice). You can view metadata and download individual records by clicking on links in the table below, where each record is identified by its depth and the name of the mooring. If you do download any of the current meter records you should review the note on file format. A brief description of the experiment is available here, and you may want to look at a map of the array to see where the moorings were. From here you can also move up one level to the list of WOCE experiments.

The initial cruise was in July 1992. Five current meter moorings (CMMs) and 10 inverted echo sounders (IESs) were deployed, and 18 CTD stations were conducted. Of the five CMMs, four (labelled B, C, D and E on the accompanying map) were recovered in July 1993, and redeployed. The four moorings were recovered for a second time in May 1994. The current meters were Neil Brown/EG&G ACM-II acoustic current meters. The ACM-II is a vector-averaging instrument that records internally on a cassette tape.

Plots of the current meter time series, as well as statistics (means, extrema, and standard deviations) can be found in the data report, "Current Meter Observations During the Kuroshio Extension Regional Experiment", by Zachariah R. Hallock and William J. Teague, issued by the Naval Research Laboratory as Report NRL/MR/7332-95-7591, and dated 22 May 1995. The authors of the report discuss "offset corrections" that they applied to the data. These corrections were designed to compensate for errors introduced by the instruments. The procedure is somewhat uncertain, and the authors recommend that the corrected velocities be used in the case of some current records, and the uncorrected velocities in other cases. The files in CMDAC's database are those recommended by the authors; that is, some are corrected and some are not.

netCDF is a self-documenting format that can be accessed by a variety of software tools. We have included here a Matlab script that can be used to read netCDF current records in an environment that contains the Matlab/netCDF interface created by CSIRO. You can Click here to learn more about netCDF.

We are aware that users who are unfamiliar with netCDF or who lack software to deal with it, may find the netCDF format more a deterrent than an aid to effective use of the data. We have included in this CDROM set a second disk that is identical to this one, except that the current meter records have OSU's "Stranger" format. The Stranger format, like netCDF, is self-documenting but utilizes the ASCII code. It is easily readable by both humans and computers; you may find it preferable to netCDF.
