I am undertaking a project to compare the results of different ocean
bottom seismometer horizontal orientation methods and welcome any
collaborators/allies. If you have published or unpublished OBS
orientations that you are willing and able to share, please get in
touch with me.<span class="HOEnZb"><font color="#888888"><br>
