Brad Colman
AMS President

The AMS has had a lasting impact on me and my career; I am both thankful and humbled to have this opportunity to serve as its president. Over the more than 40 years that I have been a member, the scientific innovations and advances in weather and climate services have been nothing short of remarkable. The benefits to society are indisputable. The mission of the AMS is to promote and support this success and it does so through its excellent staff, leadership, and volunteers. As the vulnerabilities of the world are increasingly tested by extreme weather events, I am particularly thankful for the AMS community and proud of the tremendous value it brings to the nation and beyond.

Fast Ice

(Also called landfast ice.) Sea ice that is immobile due to its attachment to a coast, usually extending offshore to about the 20-m isobath.

In protected bays and inlets, fast ice is smooth and level, typically reaching a thickness of between 2 and 2.5 m. Along exposed coastlines, fast ice may be greatly deformed.
