      <Desc>MEETINGS - AGU has a diverse meeting portfolio that offers meetings of various sizes and formats. Most meeting participants present a poster and/or a talk on their latest scientific findings contributing to advancing Earth and Space science. Individuals must pay a registration fee to participate. The abstract submissions covering their presentations are published as part of the scientific program for each meeting and available via AGU's website. The AGU Fall Meeting is recognized as the leading meeting in the Earth and space sciences community with programming focused on inter- and multiple disciplinary sciences and policy and societal issues. It is the largest meeting in this field attracting more than 24,000 participants at the December 2015 meeting. The meeting generates hundreds of press and media stories about Earth and science sciences in prominent sources through distribution on the television, news print and through other electronic outlets. The Joint Assembly is a unique platform for scientists and researchers to connect with their Canadian and U.S. colleagues in an intimate setting. With more than 2,000 attendees, the meeting covers the entire Earth and space science spectrum but is small enough to allow for strong collaboration. In addition to a robust scientific program, attendees have the option to attend field trips, workshops, and short courses, covering a wide range of topics to spark scientific innovation and discussion. The 2015 Joint Assembly was held in May 2015 in Montreal. This meeting is cosponsored by AGU, Canadian Geophysical Union, Geological Association of Canada, and Mineralogical Association of Canada. The Chapman Conferences are small topical conferences that focus on current and emerging science issues. Five Chapman conferences were held in 2015 in four different countries with attendance ranging between 70 - 120 participants. The 2015 AGU-SEG Workshop was held in August 2015 in Keystone, Colorado. This yearly workshop, jointly sponsored by AGU and the Society of Exploration Geophysicists, brings 75 - 125 attendees together with a single scientific tract and a narrow scope of content.</Desc>

        <Desc>Marketing, Communication and Engagement - Marketing, communications and engagement programs seek to: 1) build and maintain AGU's reputation as a leader, collaborator and sought after partner within and outside of the Earth and space science community; 2) promote AGU and its programs, initiatives and services to current and potential members, as well as to the broader Earth and space science community; and 3) educate the public, at all levels and across all sectors, on the importance and impact of the Earth and space sciences, particularly as it relates to societal well-being. Major accomplishments in these areas during the 2015 fiscal year include: expanding and elevating Eos.org content (Eos is a website and bi-weekly magazine dedicated to providing news and perspectives about the Earth and space sciences and their impact), and introducing a weekly email newsletter; relaunching AGU's Virtual Options (now AGU On Demand) program to included streamlined content and an improved user experience; expanding programming offer by the Sharing Science program, which seeks to educate and empower scientists to share their knowledge with the public, and building its network of scientist participants; increasing mainstream and industry-specific media coverage of AGU and its science by nearly 20% over fiscal year 2014; increasing social media engagement across all AGU platforms, including a nearly 100% increase on Facebook, and launching a new series of AMAs on Reddit; and exhibiting AGU membership/services/programs at least 7 industry-related events.</Desc>

        <Desc>SCIENCE - The AGU Science Department is responsible for AGU talent pool and professional education programs - providing support to AGU members through all career stages; and for serving as focal point for scientific program-related activities which cut across AGU disciplines, including areas such as scientific ethics programs, honors and recognition programs for AGU members, and for AGU scientific initiatives such as the Thriving Earth Exchange Program. Key highlights for AGU talent pool programs in 2015 were a 50% growth in the AGU Student and Early Career Conference, introduction of an AGU meeting-mentorship program, and the introduction of a promising new program - the Virtual Poster Showcase - allowing students to present their research and receive feedback from anyplace across the globe. Each of these three emerging new talent pool programs received strongly favorable feedback from participants to encourage continued growth. AGU's student travel grant activities also expanded in 2015. AGU provided travel support for more than 225 students to participate in the 2015 Fall Meeting and provided all-expense paid full support to 18 Berkner students from developing nations to participate in the 2015 San Francisco AGU Fall Meeting and the 2015 Montreal Joint Assembly Meeting. This year also saw the growth of student and early-career member support through a special $5000 allocation to each of the 23 AGU Section and Focus Groups to help encourage and support student program initiatives. The AGU Outstanding Student Paper Award program in 2015 enjoyed over 2600 student participants and engaged over 2000 volunteer judges. AGU's scientific partnerships expanded in 2015 to include programmatic activities with the International Association for the Promoting GeoEthics (IAPG), and new a partnerships with the American Society for Microbiology (ASM), leading to new joint-interdisciplinary scientific meeting activities. The AGU Thriving Earth Exchange program also grew its partnerships and impact in 2015, and is now providing solutions to more than 15 local communities across the globe, on issues associated with climate change, natural resource limitations and natural disasters.</Desc>
