About The Hydrographic Society of America (THSOA)
The mission of THSOA is to promote education in hydrography.
THSOA was incorporated in the State of Maryland (United States) as a non-profit organization in 1984 and was granted 501(c)(3) status as a non-profit organization by the U.S. Internal Revenue Service in 1985.
Individual Members of THSOA are eligible for membership in local chapters, and receive a discount on registration at THSOA sponsored events as well as some international conferences. Local chapters have been formed in Houston Texas, the Gulf Coast (Louisiana, Mississippi, and Alabama), and the West Coast (Alaska, Washington, Oregon, and California).
Members also receive Hydro International (HI) Magazine which is published ten times a year plus a buyers quide. THSOA ensures that your address is current and takes care of the periodic process of BPA subscription certification.
On odd numbered years THSOA hosts the U.S Hydrographic Conference which alternates with the Canadian Hydrographic Conference (held on even years). THSOA was the co-organizer, with NOAA's Office of Coast Survey of the original US Hydro Conferences which were held held from 1984-1994. In 1999 THSOA organized the "reborn" US Hydro event.
In recent years we have worked very hard to strenghten our already strong ties with the Canadian Hydrographic Association (CHA; See also Links and References). We now offer a reciprocal arrangement on Exhibiting and Registration fees for our respective annual conferences.
THSOA Corporate Members receive the same benefits as Individual Members plus a hot link on the Corporate Member page. Corporate membership includes two Individual Memberships. For the biennial U.S. Hydro Conference they receive a discount on exhibit space and may register any three employees of the organization at the member rate.
Only Corporate Members and Government Agencies may place Employment Opportunity advertisements (no charge).
All memberships begin on entry and are renewed on January 1. Dues are not prorated. Persons joining after October 15 will receive the remainder of the present year plus all of the next. This is a one time benefit and does not apply to former members who wish to be reinstated.
THSOA is staffed by volunteers; we have no paid staff. Our mailing address (no office) is Hydrographic Society, 451 Hungerford Dr Ste 119-360, Rockville, Maryland 20850. Our answering machine and our FAX is 240-209-0795. Our IRS TIN is 52-1332749.
