As a former Navy officer I was constantly reminded of the power, wonder and complexity of our world’s oceans. As Americans we are blessed by our location, surrounded by two of the world’s great Oceans, along with the magnificent Great Lakes along our Northern border. Oceans and coastal waters provide us with critical resources, hours of recreation and protection.
The environmental health of the oceans and the Great Lakes is a complex, multi-faceted issue requiring attention and action from numerous perspectives. It requires effective coastal zone and watershed management, both point and non-point water pollution management, and more effective fisheries management. It requires coordination and action by local, state and federal government agencies, by addressing issues like invasive aquatic species to agricultural runoff. It is one of the more complex management challenges facing the environment because the ocean ecosystem is affected by so many different activities and sources under so many different management jurisdictions – from sewage discharge treatment facilities, to air pollution depositions, to climate change. For example, the “dead zone” in the Gulf of Mexico which appears every summer does not result from human activities in the Gulf of Mexico, but from human activities across the Mid-West.
The U.S. Commission on Ocean Policy has provided government leaders with an “Ocean Blueprint for the 21st Century” that has many good ideas; however, even it struggled with the enormity of the management challenge that lies before us, and recognized that there are no easy answers. This is at least partly due to the fact that so many of the human activities that adversely affect ocean health are not “ocean activities”, but are landside activities. Regional and ecosystem management concepts are easy to talk about, but are complicated to implement effectively, and they depend of obtaining a commitment from various necessary stakeholders.
Ocean health and policy requires better management focus; however, we also need a better scientific understanding of the oceans. In no area is this truer than in obtaining a better understanding of the interaction of climate change and the oceans. We need to better understand the ocean’s role in the carbon cycle, in the effects of the massive amount of fresh water resulting from the melting of polar ice, which could dramatically affect global weather patterns, and in the effects of warmer ocean waters on weather – especially coastal storms - and on marine life. Ocean science and engineering is a field that deserves greater attention and focus.
Although I have served the State of Arizona in the United States Senate, I have always had an enormous attraction to and appreciation for our oceans. Their health requires an increased focus and commitment from all Americans, not just from those who derive their livelihood from them or live on their shores.
