All membership applications and renewals should be submitted & paid to The Hydrographic Society of America at www.thsoa.org. In recent months members have been renewing their memberships via the Houston Chapter website at http://houston.thsoa.org instead of through the National website.
We ask members to please apply, renew and pay for their membership via the THSOA website as it streamlines the membership application/renewal process. The Houston Chapter website should only be used for Houston Chapter events registrations.
If you have any questions or concerns, please contact the administrative assistant at email@example.com.
