Ocean observations

Seen from satellites in space, the Earth is a blue planet with three quarters of its surface covered by water. The ocean, however, does not function in isolation and is part of an integrated Earth system, comprising land, water, and the atmosphere and their associated ecosystems. Thus changes in the ocean can have a dramatic impact on human populations and all life on Earth, through for example, its impact on our climate. As the temperature of the oceans change, many impacts are felt including changes to the major current systems, the intensity and frequency of storms and the distribution of sea ice. These will have a profound impact on shipping, which is vital for transportation of resources around the globe.

A disproportionate number of people reside around the ocean rim. It is vital that, as a world society, we learn as much as possible about the ocean, how it functions, and how it might respond to climate change. Moreover, we should continue to monitor the ocean into the indefinite future so that we can detect and quantify any changes that might occur in its biogeochemistry, ecosystem or physical dynamics. Fundamental to this is the need for reliable ocean observations. It is the function of POGO to be an advocate, in the broadest sense, for such observations and to communicate their value to society-at-large.

At this crucial stage, scientists worldwide are working towards the establishment of a comprehensive network of observational instruments that will criss-cross the world’s oceans. As ocean science advances and moves more towards operational science, nations around the globe need to invest in a continuous integrated ocean observing system to make this vision a reality. Since its conception POGO has strived to forge networks around the world to promote long-term cooperation in global ocean observations. Only through the development of a more comprehensive observing system can scientists provide reliable information and advice to policy makers to maintain and sustain human life as we know it.

Unfortunately some nations do not have the capacity to make the detailed ocean observations that we need, and for vast stretches of coastal margins lying in the developing world we are limited by a lack of trained personnel. An enabling mechanism is needed through which coastal states in the developing world can establish the knowledge base for responsible stewardship of their patrimony. POGO is helping to make this a reality, through its education and training programmes.
