Historical tide measurements are among the oldest direct observations which provide relevant information regarding the long-term evolution of mean sea level. In many countries, systematic sea level observations have been carried out since the early to mid 1800s. Despite this rich historical legacy, documents with these records are hidden in archive centres. Most of these analogue documents are not adequately inventoried. There can be considerable benefit in rescuing these data before they may be lost.
At a joint meeting between the Tides, Water Level and Currents Working Group (TWCWG) of the IHO (International Hydrographic Organisation) and the Global Sea Level Observing System (GLOSS) Group of Experts from 11-13 April 2019 in Busan (Republic of Korea) it was agreed to organize an international workshop on "Sea Level Data Archaeology". The main objective is to bring together experts concerned with sea level data rescue activities to explore the potential for a more sustained programmatic approach to cooperation at the international level.
This meeting has now been organised under the auspices of the Intergovernmental Oceanographic Commission (IOC) of UNESCO and its Global Sea Level Observing System. The IHO TWCWG is a co-sponsor of the event. There is no registration or attendance fee, but advance registration is required: see the workshop website. Abstracts for oral or poster presentations should be submitted by 1 February 2020: further details are given in the official announcement.
