Profile
We are a coral reef conservation research institute dedicated to providing services that will help save coral reefs. Unfortunately, we went with the "you've gotta spend money to make money" approach, whereby we did primarily pro bono consulting work. This led to approximately a ~$4,000 net loss in income over the course of the year. Hopefully, we will not be operating in the red in 2024-2025.

Mission and Program Overview
Mission
We are a coral reef conservation research institute dedicated to providing services that will help save coral reefs. Unfortunately, we went with the "you've gotta spend money to make money" approach, whereby we did primarily pro bono consulting work. This led to approximately a ~$14,000 net loss in income over the course of the year. We did secure a $5,000 award to help with analysis of marine biology data (data analysis being amongst our core serfices).
Program Services
| Description | Grants | Expenses |
|---|---|---|
| We conducted a number of coral reef field surveys pro bono to help developing countries manage their coral reefs: Mauritius, Mexico, and several others. I am hoping this "spend money to make money" approach (good karma) will help get for-pay survey and diagnostic contracts in 2026 and beyond. | $0 | $9,629 |
| As described elsewhere, we also attended several coral reef and marine conservation-focused conferenced at our own expenses to advance our mission of saving coral reefs. | $0 | $9,629 |
