Unspecified amount

What is Sea Grant?

Founded in 1968, the University of Hawaiʻi Sea Grant College Program (Hawaiʻi Sea Grant) is part of a national network of 34 programs that engage in the better understanding, conservation, and use of coastal ecosystems. Hawaiʻi Sea Grant works in partnership with the University of Hawaiʻi’s prestigious School of Ocean and Earth Science and Technology and the National Oceanic and Atmospheric Administration (NOAA) to identify Hawaiʻi’s key environmental management issues and guide cutting-edge scientific research to address these challenges.

Pacific Islands Coastal Health Fellowship Program (PICH)

The Pacific Islands Coastal Health Fellowship is a place-based program for recent graduates from the Pacific Islands who want to return home and gain meaningful, hands-on experience in environmental and community work. Fellows will be placed with organizations in Hawaiʻi, American Samoa, the Republic of the Marshall Islands, the Federated States of Micronesia, Palau, the Commonwealth of the Northern Mariana Islands, and/or Guam. Placement is dependent on fit between applicant and host organization.

Coordinated by the Hawai‘i Sea Grant Center for Pacific Ocean and Island Health and the Pacific Islands Ocean Observing Systems (PacIOOS), the fellowship places early-career professionals full-time within local government agencies or community organizations working on projects related to fisheries and coastal health. Fellows will work in partnership with participating government agencies or community-serving institutions to work on priorities identified by those agencies and their communities. Focus areas include fisheries, ciguatera, water quality, marine debris, and human health, reflecting the everyday land–sea issues island communities face.

Fellows can expect to gain skills in research, management, outreach, and education. They will receive professional training and support throughout their fellowship period. This fellowship should equip recent graduates to transition into graduate school or into a meaningful career at the conclusion of the year. We hope they will build lasting relationships with host organizations and mentors that will support long-term collaborations and project support.

Oregon Sea Grant: Program Development Grants

Oregon Sea Grant
State/Local Government
Oregon
Up to US $10,000

Oregon Sea Grant

Established at Oregon State University in 1971 as one of the first four Sea Grant College Programs designated in the nation, Oregon Sea Grant is now one of 34 programs within the National Oceanic and Atmospheric Administration's Sea Grant College Program. Congress established the national Sea Grant program in1966. Oregon Sea Grant is cooperative program between NOAA and Oregon State University. Our programs serve all of Oregon. Our core-funding is from NOAA Sea Grant and requires a 50% match of non-federal funding. Oregon State University is our primary non-federal fiscal partner, but we rely on many other collaborators and partners, including local governments, agencies, industry, and philanthropy to expand our capacity to address ongoing, unexpected, and emerging needs of Oregon's coastal communities and ecosystems.

We address regionally and nationally strategic issues through an integrated program of competitive, rigorously reviewed research, extension services and projects, and public education. We support dynamic, inventive, and flexible approaches to meet the needs of communities in changing natural and social environments.

Program Development Grants

Oregon Sea Grant offers modest grants for project opportunities or special circumstances when resources are available.

These funds generally are not intended to supplement an existing project, but to provide seed money for exploratory or high-risk efforts, or to respond to urgent needs or unforeseen opportunities that require a timely effort.

Purpose

In addition to competitive grants awarded on a two-year cycle, Oregon Sea Grant offers modest grants for project opportunities or special circumstances, when resources are available. These projects typically arise between the regular application periods and must align with the Oregon Sea Grant strategic plan. These funds generally are not intended to supplement an existingproject, but to provide seed money for exploratory or high-risk/impact efforts, or to respond to urgent needs or unforeseen opportunities that require a timely effort. Oregon Sea Grant also considers requests for event support (or total requests less than $2,500) through our Conference and Activity Support program (see the Oregon Sea Grant “Conference and Activity Support Policy” for details).

Funding

Development grants are modest in size (total awards typically do not exceed $10,000) and should be one year or less in duration. Larger requests are occasionally considered, and are subject to peer review and approval by the National Sea Grant Office. Given our limited funding, success of requests in excess of $10,000 (total award) will be lower. While cost share is not required for program development proposals, opportunities for leveraged funds are welcome. Please contact us to discuss possible cost share for your project.

Program Development Submission Eligibility for April – December 2026 ONLY: Anyone residing in Oregon who can receive a personal services contract from OSU and is / can be set up in the Federal SAM system is eligible to apply for Oregon Sea Grant (ORSG) Program Development funds up to $6,700 (direct costs) during the period April – December 2026, funds permitting. Awards over $6,700 (direct costs) will be made only through colleges and universities.
