Tasks of Work Package 4
Last edited 29 January 2004
T4.1: Comparison of tide gauges: at selected sites, a pilot station will be established
in order to test different kinds of tide gauges: acoustic, radar, pressure sensor, etc. This station will be in operation for one year, and results from these comparisons will be
used to decide in task 4.2 on the upgrading of gauges (P5, P6).
T4.2: Upgrading tide gauge stations: A number of important ESEAS sites (in areas with
sparce coverage, particular geographic locations,
long-term gauges) are still analog gauges or even manual. It is planned to upgrade these
gauges to up-to-date digital gauges. The sensor will be selected on the basis of
the result from T4.1 (P8, P9, P10, P12, P13, P15, P17, P18).
T4.3: Co-location of tide gauge stations with GPS: Application A and C gauges need to
be co-located with GPS in order to be able to measure absolute sea level changes or
to provide sea level in the same reference frame as the satellite altimeters. Selected
ESEAS sites determined in WP1, task 1.1, will be co-located with permanent CGPS
(P1, P4, P5, P6, P8, P9, P10, P11, P12, P15, P17, P18, P20).
T4.4: GPS Campaigns at tide gauges: At some tide gauges, GPS campaigns
will be carried out in order to connect the tide gauges to a global
reference frame (P7, P9, P15, P18, P20).
