The Inexpensive Device for Sea Level Measurments

Date:15 Mar 2015

A new mareograph device has been designed at the Joint Research Centre (JRC) of the European Commission (EC) in order improve the sea level network in use for the Tsunami Hazard monitoring in the Mediterranean Sea and in the North Atlantic area (NEAMTWS area of UNESCO). The instrument has the characteristic to be cheap and very effective but its reliability, duration and quality need to be determined and qualified. For this reason a number of experimental campaigns are being conducted, whose first results are presented here. In collaboration with the UNESCO/IOC (Intergovernmental Oceanographic Commission), responsible of the definition of the Tsunami Warning System of this geographical area, a set of 20 devices has been offered by JRC for a period of 1 year of testing of the devices; the surveys for the installation of the devices is under way and the installation should be completed by the end of 2015.

IDSL Installation Guide

Date:18 Oct 2015

The objective of this guide is to explain the best sequence of operation for successfully install and put in operation one Inexpensive Device for Sea Level measurements (IDSL). The guide is the result of the installation of at least 5-6 instruments in various conditions. Reading the guide may help to have a better preparation and solve problems before they appear. Nevertheless, a degree of “improvisation” is always necessary because each installation site is different from another and specific solutions are necessary.
