"The goal of U.S. GLOBEC is to identify how a changing global climate will affect the dynamics of marine animal populations and
ultimately how climate change will globally affect living marine resources. The strategy of U.S. GLOBEC field programs is to focus on
processes and mechanisms linking physical factors to the population dynamics of marine animals. As a simplifying assumption, the focus of
the field work is on the population dynamics of the planktonic stages of marine animals because they are believed to be the most vulnerable
to changes in physical forcing caused by climate change.
A vital step in the U.S. GLOBEC program is to link the information developed from field studies on planktonic processes, to the much larger scales of global climate change, marine population space, and the rise and fall of living marine resources. Field studies on processes, by their nature, are limited in space and time, seldom being larger than 10,000 nm2, and lasting longer than five years, while major marine populations may occupy and migrate more than 100,000 nm2 and climate change evolves over several decades to hundreds of years. Linkage of the scales of process studies to large time and space scales requires modeling and retrospective studies..."

"...The most crucial aspect of the GLOBEC program is a close connection between studies of the physical environment and biological processes in the ocean. Indeed, the GLOBEC program is based on the assumption that the physical environment plays a crucial role in at least come of the life stages of most marine animals."
