As governments tighten their belts,
it’s getting harder for them to pay
scientists to monitor the health of
the nation’s ecosystems. So increasingly,

“citizen scientists”:

It’s the kind of cloudy, wet day that most people spend indoors. But the cold and wet doesn’t matter as much when you’re planning to spend your day at the bottom of a Puget Sound fjord.

About 75 miles from Seattle, these scuba divers are conducting volunteer surveys for REEF, an organization that monitors fish populations around the world. The data help researchers understand where fish live, and in what kind of numbers. It’s the kind of information governments need to understand how fishing and pollution are affecting waterways.

Back on the boat, surveyor Janna Nichols has just emerged from the 48-degree water. She pulls out her survey and goes down the list marking off what she’s just seen.

“Sunflower stars, definitely, many of those – saw a lot of those around. No sand dollars, no sea urchins. Ah! Ooh! Ah! Here’s an exciting one! I saw a giant nudibranch! A very small giant nudibranch. But those are very cool to see – a treat!”

Identifying fish can be tricky, because the same species can have different coloration depending on its age, gender, or even time of the year.

“Black-eyed gobies were everywhere. I would say under a hundred of them. And – they were mating! Because I don’t know if you noticed, they had black pelvic fins. And they kind of hover around and say “Hey, baby baby, look at me!”

As much fun as these “citizen scientists” have, professional scientists take the data these divers collect seriously. Last summer volunteer surveyor David Jennings went diving in Washington’s Olympic National Park Marine Sanctuary. He was excited to see the colorful tiger and china rockfish he’d heard were abundant at the park. But when he got there, he only saw a couple. So he looked at the past six years of REEF survey data to see how the rockfish populations had changed.

“One of the best sources was someone that wrote up a diving experience he had in 2002 where he saw dozens of tigers and many chinas. Whereas I in a week of diving saw two tigers and just three chinas. so it was a very big contrast to what people saw in the past.”

Jennings took the data to the Washington State Department of Fish and Wildlife. That’s the agency that decides fishing limits. Greg Bargmann is a department fisheries biologist who’s working on next year’s catch limits for rockfish. He says even though the REEF divers aren’t as highly-trained as the state biologists, the data they collect are more current and cover a wider area.

“The REEF survey shows a very dramatic decrease in abundance over the last five years. Our state surveys don’t show that, but we have a lot of imprecision in our surveys so we’re relying on the REEF surveys to look for changes in population.”

That’s because the state can’t afford to send its biologists out as often or to as many sites as the volunteers dive.

“We really appreciate the interest of our citizens to spend time going out there and using their own transportation costs and their own equipment to go out and collect data, and to listen to us and collect things that are not easy to do sometimes.”

You don’t have to dive to be a citizen scientist. In Ohio, citizens track everything from salamanders to spiders. In California, tighter budgets mean more poaching – and not enough game wardens. So states are training volunteers to do more work. And across the country, the Environmental Protection Agency relies on citizens to monitor water quality in lakes and streams.

Bargmann says while governments rely on citizen scientists more during budget crunches, he sees programs like these becoming increasingly important for keeping track of the health of the environment.
