... Oceanography needs to define its role in a rapidly changing world Rapid technological advances in ocean observation, modeling and information systems provide the potential for nearly limitless expansion of marine research as the field of oceanography emerges from its datalimited foundations. Now, the challenge is to define the best strategies for exploiting new capabilities while justifying the required investments when resources are limited.

... Consequently, the role of the ocean in global climate change, and the effects of climate variability on living marine resources including fisheries, can be understood only by observing, describing and ultimately predicting the state of the ocean as a physically forced ecological and biogeochemical system. What has been lacking until recently is the capability of integrating the study of physically forced ecosystem dynamics and biogeochemical cycling across scales, from: • The mesoscale (with spatial scales of order 10-100 km and tempo ral scales of order 10 to 100 days)

... These observations will form the link between detailed oceanographic process studies, surveys using advanced biogeochemical analyses, and paleoceanographic reconstructions of the relationships between climate and ocean biogeochemistry. In 2025, we will have the data to test comprehensively the 20th century hypotheses about how ocean systems work (e.g., the influences of environmental variability on pelagic food web structure)
