The Global Sea Level Observing System (GLOSS), a component of the Global Ocean Observing System (GOOS), is establishing a well-designed, high-quality sea level observing network to support a broad research and operational user base.
Notice
We are very sad to inform you that Dr David Pugh, one of the founders of the GLOSS programme, a former Director of the Permanent Service for Mean Sea Level, and former Chair of the Intergovernmental Oceanographic Commission passed away on 1 August. He will be greatly missed by many friends and colleagues in sea level science and science management in different countries. A summary of David's life and many accomplishments has been posted on both the IOC and NOC websites.
Sea level data are vital for
Research into sea level change and ocean circulation
Coastal protection during events such as storm surges
Providing flood warning and monitoring tsunamis
Tide tables for port operations, fishermen, and recreation
Defining datums for national or state boundaries
Sea level is one of the most useful oceanographic variables, used for a wide variety of scientific, economic and social purposes.
