MEDS acquires, processes, quality controls, archives and distributes
tide and water level (TWL) data reported on a daily to monthly basis
from the DFO Canadian Hydrographic Service (CHS) water level gauging
network.
MEDS also operates a Tides and Water Levels Benchmark Database for the Canadian Hydrographic Service where information on the benchmarks from various DFO stations can be found.
As Canada's national data centre, MEDS historical tides and water
level data archives presently hold over 30 million records with the earliest dating back
before the turn of the century. Over 70,000 new hourly height observations and other
higher resolution data are added on a monthly basis. Data are also exchanged
annually with Environment Canada.
MEDS also participates in the Global Sea Level Observing System
(GLOSS) by contributing data from
the Canadian network on an annual basis.
