GLOSS/IODE Sea Level Data Archaeology
In 2001, GLOSS and the International Oceanographic Data and Information Exchange (IODE) programme initiated a Data Archaeology Project, coordinated by Dr Lesley Rickards. It aimed to rescue sea level information that existed only in analogue form (charts, paper tape, etc) and convert it to a digital form.
For more information on the project, read the letter (32 kB) circulated to the GLOSS and IODE contact lists requesting all countries assess their holdings of potentially rescuable historical tide gauge data.
To provide information to the project, please download and complete the questionnaire in
Completed questionnaires have been received from:
If organisations need help in converting their paper records into computer form, they should contact either the GLOSS Technical Secretary or the Permanent Service for Mean Sea Level (PSMSL) (see Links and contacts).
Data Archaeology for the ESEAS-RI project
The European Sea Level Service Research Infrastructure (ESEAS-RI) project ran from 2002-2005. ESEAS established the project to support its research infrastructure and facilitate full scientific exploitation of European sea level observations.
The primary scientific objective of ESEAS-RI was to study sea level variations at inter-annual to century time scales and assess potential future changes in mean sea level. The study was based on combined sea level observations from tide gauges, which give long time scales (up to two centuries) and satellite altimetry, which gives increased spatial resolution over a shorter period.
To increase the length of data sets available to the study, a survey of potential data (charts, etc.) for "data archaeology" rescue was carried out. The following catalogue of paper-based data sets (last updated 01 November 2003) is based on a survey carried out by Dr Lesley Rickards.
A questionnaire was sent out to all partner organisations, and the following responses were received:
Data Archaeology projects around the world
Below is a short list of a number of data archeology projects that GLOSS has been made aware of.
