In an effort to demonstrate MB-System™ in as realistic manner as possible we have provided several real datasets as examples.
The standard MB-System™ distribution comes with an archive of example data sets and scripts generated using MB-System™ (MB-SystemExamples.X.Y.Z.tar.Z). While these are not referenced directly within the Cookbook, they can be helpful examples and since their size is small they have been retained. When uncompressed and un-archived, the resulting directory tree will resemble the lines below.
[vschmidt@val-LDEO mbexamples]$ ls data mbbath mbgrid mbinfo mblist mbm_plot README xbt
The ~/data directory contains several sample data files used in these examples. The other directories contain scripts that briefly demonstrate the use of several of the tools in MB-System™ .
For the purposes of the MB-System™ Cookbook, however these data sets were not sufficient to demonstrate the intricacies of various processing techniques, nor the art of managing a data set within a larger archive. Therefore, for the purposes of the examples contained herein, you will find two separate collections of data that are freely download-able such that you may follow with each step we demonstrate.
The first collection of data has been added to the mbexamples tar file. Within mbexamples/data/other_data_sets you will find a collection of directories each with smaller data sets used to illustrate some particular processing technique in MB-System™ . For example, discussions surround calculating roll bias and sound speed profiles utilize data sets in mbexamples/data/other_data_sets/rollbias and mbexamples/data/other_data_sets/ssp, respectfully. A directory called ~/mbexamples/cookbook_examples has been created which will serve as a home directory for calculations utilizing these data sets.
To illustrate the processing and managing of data within a larger data archive we have provided a completely separate archive containing several data sets mapping the volcanic seamount Loihi off the southern coast of the big island of Hawaii. Within the loihi data archive you will find four data sub directories, each with their own Loihi data sets. Extensive data processing has been conducted on the data sets with the exception of the MBARI1998EM300 data. It has been purged of editing changes to better illustrate these examples; only the raw data files remain. This directory contains ~140 MB of data - a more manageable amount to download than the entire 600 MB archive. Since some users may prefer to have the entire archive, as it affords the ability to see how to process and manage a large archive with MB-System™, we have provided tar files for both the full archive and just the MBARI1998EM300 data set.
