Mission

Explore protect the ocean by advancing public awareness of the oceans importance as Earths life support system, furthering scientific knowledge of ocean systems igniting public support for a network of MPAs--Hope Spots--Mission Blue aims to save and restore the ocean. Collectively, with the ocean community, our goal is 30 protection by 2030.

Activities or mission (Part I)

Mission Blue inspires action to explore and protect the ocean through a global network of Hope Spots, advancing science, community leadership, and policies to protect 30 of the ocean by 2030.

  • Hope Spot Program Mission Blue designates and supports ecologically significant ocean regions known as Hope Spots to promote marine conservation and community-led protection. Hope Spots are nominated by local scientists and advocates, then supported through capacity building, communications, science tools, and partnerships that drive measurable conservation outcomes. As of 2025, the Hope Spot Network includes 167 sites across 115 countries, spanning approximately 58 million square kilometers of ocean.

    Expenses $853,318 · Grants $442,578

  • The Science and Exploration Program strengthens Mission Blues data-driven conservation work. Through partnerships with Esri, universities, and research institutions, the program uses GIS technology, environmental DNA eDNA, and field expeditions to map biodiversity, track ocean health, and inform protection strategies. This science underpins Hope Spot designations, policy advocacy, and management planning. The program also hosts scientific workshops and supports data integration for the global Hope Spot Network.

    Expenses $618,058 · Grants $185,000

As filed on the 2024 return. The filer continues this part on Schedule O, which is not shown here. A text marked withheld matched a screen for wording that may name a private individual, such as an honorific or "in memory of". Most of what it withholds names no one; it is withheld so that what does is never shown.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
