Mission

We fully exploit the physical and human resources of the Salish Sea to equip high school students with knowledge, skills, career awareness, and confidence for civic life and college and career success, most especially in STEAM fields. Salish Sea Sciences brings motivated high school students from all backgrounds together with scientists and other professionals to learn from and protect the Salish Sea, its creatures, and people in multi-week summer residential programs and intensive multi-week school-day programs in Seattle public schools focused primarily on marine field and lab research and ecology and conservation. We serve students from the San Juan Islands, the greater Salish Sea region, the state of Washington and multiple other states as well as other countries. Our mission is (1) grow a community of critical thinkers, 2) bring innovation to public engagement in science, 3) raise awareness of science as a career path, and 4) advance a more diverse cohort of investigators.

Program accomplishments

  • Residential Programs on San Juan Island include our flagship summer 4 week Marine Field & Lab Research program and the 2 week Marine Ecology & Conservation program. The 4-week program concludes with student presentations of science posters, completed to professional specifications, of independently designed and executed research projects to the public --including staff, contributing mentors, family, and community members. The 2-week Marine Ecology & Conservation program concludes with a public 5 minute elevator pitch with visualization of a preliminary project proposal, based on what they learned with us in the San Juan Islands, and that they (or someone their age) could reasonably implement in their home area, whether in concert with existing initiatives or independently. These projects are templated with prompts such as typically found in RFPs, grants, corporate departments, etc--such as accounting for potential budget needs. Benefit: 40 students (3 full scholarship); 37 contributing mentors (12 paid/25 volunteer; 6 staff). Contributing mentors represent multiple institutions and organizations, including University of Washington affiliated researchers and scientists from other institutions pursuing their investigations at the UW marine laboratories. Others include representatives from San Juan County, a local fishery, and an array of .orgs. Some of these mentors engage with our students in their capacity as employees of a mission aligned organization whereas others, such as PhD students, Post-Docs, and young university faculty gain resume and grant requirement benefits. Additional beneficiaries include staff members supplementing their income with summer employment and island purveyors of products and services like food, vans, gear and equipment, and on-water experiences like kayaking. We rent our facilities from a local independent school, providing them with additional income. For summer 2025, volunteer mentors and a local museum provided $4,800 in donated services.

  • School-based programming for Summit Public Schools: 2-week Ecology & Conservation intensive for Summit Atlas High School and 2-week Ecology & Conservation intensive for Summit Sierra High School, both of Seattle, WA. Marine Ecology & Conservation: engage students with marine science, ecology, and conservation institutions, practitioners, methods and tools, deepening students' scientific and ecological perspectives of their Salish Sea home and acquainting them with a wide array of professions related to understanding and protecting the Salish Sea, its creatures, and its people. Students create a 'preliminary project proposal' to present to classmates and guests on the last day, recommending an engagement pathway for high school aged students. Our goal is that with limited classroom time, extensive site-visits and engagement with multiple guest mentors representing a wide array of .edu, .gov, and .orgs, the personal stories of those guest mentors, and the students' individual project research and presentations will stimulate their connection to place and their personal agency as individuals and citizens to engage with their environment and communities. We aim for our programming to both inform and support student's college and career goals and trajectories. Salish Sea Sciences' shares with Summit Public Schools a commitment to support students' sense of belonging and personal agency--rooted in science and connected to place and community--engendering leadership skills and informed college and career choices. Summit Public Schools provide a rigorous, supportive, and inclusive learning environment to a diverse group of passionate young people. They are committed to ensuring that 100% of their students graduate with concrete next steps after high school. They serve a diverse student population across many lines, consistent with the school districts in which they operate. Together, we work so that these young people become leaders and contributors to the greater Salish Sea region and anywhere else they may go. During 2025, our primary activities for Summit programming was making the plan to follow through with the original design which is to have students on rural San Juan Island residentially for the first week, followed by school-day programming in the greater Puget Sound area in and around Seattle for the second week. Accordingly, we planned two scenarios, one with a potential rental of dorm space to house students and their school chaperone and one where they camp. In light of the possibility of camping, we postponed the programs to the spring of 2026 to take advantage of better weather during the schools' available expeditionary periods. Hence, we had no revenue for this programming during 2025, though we spent considerable time on planning and writing grants for this purpose. Please see Accomplishment Three for details as these activities are consistent with the "administrative" domain described in Accomplishment Three.0
  • During School Year Development: As is always the case, the non-in-program period of the year requires focus on maintaining and cultivating our programming with a functional, up-to-date website, admissions, relationship building, grant writing, and ordinary administrative tasks. Outside of the usual tasks, our preoccupations for 2025's non-in-program months were as follows: 1) completion of report and review for Accreditation Mid-Cycle review period. (2) We continued effort regarding the Semester School, most especially as a new residential possibility presented itself. Activities in this regard focused most especially on possible rental agreement scenarios and how the availability, needs, and timing of the potential lessor property might or might not synch up with ours, especially given the academic calendar. This focus also included developing plans regarding the emergence of a new opportunity to grow Salish Sea Sciences' research, education, and outreach programs on yet another property that could serve these purposes for both Salish and other aligned organizations. (3) We also explored the possibility of short-term rentals for school-year programs like Summit's. (4) We initiated plans for two 2-week hybrid residential/school day programs for Summit Public Schools (and potentially others) to initiate in the spring of 2026. (5) A great deal of time was spent on administrative updating, most especially of filings, processes, and forms. Volunteer services donated services include $6,400 for a senior real estate attorney (16 hrs/$400hr) and $4,800 for a non-profit development consultant (32 hrs/$150hr) which adds up to $11,200.
