First, I need to thank my advisor and mentor Doug Wiens for his support, guidance, and patience during my time here at Washington University. My wife, Lindsey, and daughter, Anika, have constantly provided love, support, distraction, and the oft required kick in the rear that have lead to the completion of this volume. I would also like to thank the other great people who work in the seismology group here particularly, Patrick Shore for the friendship and guidance he has offered me, Ghassan Aleqabi for forcing me to return to first principles, Garrett Euler, Moira Pyle, and Erica Emry for suffering with me through life as a graduate student. Many thanks to all of the graduate students, past and present, for their friendship and the front office staff for keeping me aware that there are indeed deadlines and rules. I also need to thank all of the people involved in the collection of the data I present here. Thanks to the TAMSEIS, GAMSEIS, POLENET, MARIANA, and TONGA06 field teams who are too numerous to list, this dissertation could not exist without your hard work. I owe a deep debt of gratitude to the National Science Foundation, which provided the financial resources to undertake these projects and the PASSCAL division of the Incorporated Research Insitutions for Seismology (IRIS) for providing instrumentation and seismic data. Finally, I want to thank my parents for always encouraging me to reach for more, do what I love, and pursue my own path through life. ii Table of Contents Table of Contents

At its tenth meeting, the Conference of the Parties to the Convention on Biological Diversity (COP 10) requested the Executive Secretary to work with Parties and other Governments as well as competent organizations and regional initiatives, such as the Food and Agriculture Organization of the United Nations (FAO), regional seas conventions and action plans, and, where appropriate, regional fisheries management organizations (RFMOs), with regard to fisheries management, to organize, including the setting of terms of reference, a series of regional workshops, with a primary objective to facilitate the description of ecologically or biologically significant marine areas through the application of scientific criteria in annex I to decision IX/20 as well as other relevant compatible and complementary nationally and intergovernmentally agreed scientific criteria, as well as the scientific guidance on the identification of marine areas beyond national jurisdiction, which meet the scientific criteria in annex I to decision IX/20 (paragraph 36, decision X/29). 2. In the same decision (paragraph 41), the Conference of the Parties requested that the Executive Secretary make available the scientific and technical data and information and results collated through the workshops referred to above to participating Parties, other Governments, intergovernmental agencies and the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) for their use according to their competencies.

  • Tonga SUMA Report
    BIOPHYSICALLY SPECIAL, UNIQUE MARINE AREAS OF TONGA EFFECTIVE MANAGEMENT Marine and coastal ecosystems of the Pacific Ocean provide benefits for all people in and beyond the region. To better understand and improve the effective management of these values on the ground, Pacific Island Countries are increasingly building institutional and personal capacities for Blue Planning. But there is no need to reinvent the wheel, when learning from experiences of centuries of traditional management in Pacific Island Countries. Coupled with scientific approaches these experiences can strengthen effective management of the region’s rich natural capital, if lessons learnt are shared. The MACBIO project collaborates with national and regional stakeholders towards documenting effective approaches to sustainable marine resource management and conservation. The project encourages and supports stakeholders to share tried and tested concepts and instruments more widely throughout partner countries and the Oceania region. This report outlines the process undertaken to define and describe the special, unique marine areas of Tonga. These special, unique marine areas provide an important input to decisions about, for example, permits, licences, EIAs and where to place different types of marine protected areas, locally managed marine areas and Community Conservation Areas in Tonga.
