Estuaries, long recognized for their local importance, form collectively an important global ecosystem, sensitive to both climate change and local pressures. This has been recognized by a 2013 U.S. workshop, which issued a set of recommendations directed at building worldwide capacity and collaborations to address estuaries as a global ecosystem. The workshop recognized that modern observation and modeling technology is poised to play a key role in advancing the scientific understanding of estuaries, and identified the need to map the resulting understanding of individual estuaries into a common global framework. An international partnership has since emerged, driven by the increasingly recognized need to advance estuarine observation, modeling, science and science translation worldwide. Anchoring the partnership is a belief that there are important commonalities across estuaries that, if explored, will prove synergistic and transformation towards understanding and sustainable management of all estuaries. On behalf of this emerging international partnership, we describe here steps that are being taken to develop Our Global Estuary. Integral to these efforts are: (a) the organization of regular international workshops, to build a common vision and global capacity and collaborative networks—the first of these workshops planned for Chennai, India; (b) the creation of a pilot project, Our Virtual Global Estuary, where a common modeling and analysis framework, supported by and supporting local observations, will be progressively put in place for estuaries across the world—with an initial set identified in Brazil, China, Portugal, Spain, and United States, and additional estuaries under consideration; and (b) exploration of synergies with global organizations (such as the Partnership for Ocean Global Observations) and global-scale programs and initiatives (such as Blue Planet), to further contextualize the role of estuaries in the earth’s sustainability.

The 21st century has seen a drastic evolution in tools and strategies • to study contemporary conditions and predict changes in individual estuaries • to translate observations, understanding and predictions into demonstrable societal benefit, • as demonstrated through the Columbia River estuary collaboratory Can we now translate knowledge and infrastructure for individual estuaries into understanding and action for estuaries worldwide as a global resource?

- Thank you to the organizing committee – My co-author Antonio Baptista from Oregon Health and Science University and I appreciate the opportunity to share with you the Our Global Estuary Initiative These are the topics I am going to cover.
- Estuaries are critically important ecosystems, with strong susceptibility to climate change, population growth and economic development. They are: Active bioreactors, buffering the coastal ocean from increased nutrient loads and other terrestrial contaminants, and humans from conventional and emerging contaminants Distinctive nurseries and migration corridors A key part of coastal margins, which are a major economic engine: 90% of the world’s cargo is transported by sea In the US alone: hydropower was in 2008 ~67% of the renewable power and 6.4% of the total power 40% of the population live in coastal margins, which generate 45% (US$6.6T) of the national GDP and support over 51M jobs
- 87% of the earth’s land is connected to the ocean via the rivers and through the estuaries.
- We need to think of our estuaries as a global system And with that thought we need to ask the question – is the global buffering capacity of the estuaries approaching a critical threshold?
- Not to speak of climate change A report prepared for HSBC by Frontier Economics: Executive Summary In 2010 the ten most populated river basins in the world were home to more than a quarter of the world population and in 2010 they generated almost 10% of GDP and it is expected that with population forecasts almost 25% of the global GDP could be generated in these most populated river basins by 2050. By 2050 in these basins is expected to be as large as the economies of the US, Japan and Germany combined. Assuming that the blue water footprint grows in line with population and there are no improvements in water efficiency or water resource management by 2050 water scarcity could be significant or severe in 7 or 10 most populated basins. If management of scarce water in these basins is not improved the growth in GDP expected in these basins may not materialize. In addition, the ecosystems which are home to nearly 25% of the global population could be permanently damaged. The 1.8-million-square-kilometre Yangtze basin constitutes 18.8% of China’s land area and accounts for 36.5% of China’s available fresh water
- High end example can be changed as appropriate So we must ask ourselves the question – are we prepared?
- Antonio Baptista leads the Columbia River collaboratory - Integration of sensors, models and information flow with diverse communities of practice – towards enhanced understanding of estuaries and their vulnerability to change, and integration of scientific understanding into regional decision making
- Made up of a pioneer array of AUVs, Gliders, Kayak, and Bottom Node – collection of physical and biogeochemical data
- In 2013 FAU Harbor Branch hosted the first National Workshop to look closer at these questions of observation, prediction in estuaries.
