.
A component of the
Global Ocean Observing System (GOOS). The IOC of UNESCO established GLOSS in 1985 originally to improve the quality
of sea level data as input to studies of long-term sea
level change. It consists of a core
network of approximately 300 stations distributed along continental coastlines and throughout each of the world’s
island groups. The
GLOSS network also supports
sea level monitoring for tsunami warning with minimum
operational standards of 15-minute
data transmissions of one-minute sampled
data.
