What Marine Mammal Stranding Center does
Mission
The Marine Mammal Stranding Center (MMSC) was formed in 1978 for the purpose of rescue, rehabilitation and release of stranded, sick or injured marine mammals and sea turtles. MMSC is the only state and federally authorized facility in the State of New Jersey to do this work.
As stated on its FY2025 Form 990.
Programs
Animal Stranding and Care:MMSC responds to the strandings of whales, dolphins, seals, and sea turtles in New Jersey and occasionally assists with strandings in other states. Since its 1978 inception, MMSC has responded to over 6,476 strandings. This program includes: MMSC response to the stranding location by staff or trained volunteers; assessment of the animal's condition; transportation of the animal to MMSC for additional assessment by veterinarian; care and treatment for injuries or illness, and eventual release back into the ocean.

Visitors learn about the types of problems the animals encounter due to illness, injury, and pollution. The building is open to the public year round, with extended hours during summer months. School children visit the Center throughout the year and summer programs are available to visitors. Programs include visiting the back bays and beaches to learn ecology, and dolphin and turtle stranding classes. Since 1983 there have been over 700,000 visitors to the museum.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $458k to $655k (+43%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 9%. Grants only. Government contracts and fees sit inside program revenue.
95% of Marine Mammal Stranding Center’s revenue is contributions — more donation-reliant than the typical peer (86% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 9 funders to 26 funders, grant income rose $27k → $217k.
7 of 51 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 25% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

How long its funders stay
54% of Marine Mammal Stranding Center's funders are still giving 3 years after their first grant; 75% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
Marine Mammal Stranding Center draws 83% of its grant income from funders outside New Jersey, across 15 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $321k arriving through sponsors registered in 6 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
