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.


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.
