Every few months someone at our club meeting asks the same question: "How do people end up diving in the big tank at the aquarium?" The answer surprises most of them. Many of the divers you see waving to visitors, scrubbing acrylic, and hand-feeding fish are volunteers, regular recreational divers who applied, passed a checkout, and now dive a shift every week or two.
If you've been looking for a way to dive more often, give back, and become part of a tight-knit group of divers close to home, an aquarium volunteer dive program is one of the best options out there. This guide covers what these programs typically ask for, what the work looks like, how the application and checkout usually go, which gear you may need to bring, and how to put yourself in a strong position when applications open.
What aquarium volunteer divers actually do
It's real work, and most volunteers will tell you that's the appeal. Across the programs we looked at, the duties fall into a few groups:
- Exhibit maintenance: cleaning acrylic windows, scrubbing rockwork and artificial coral, and siphoning debris off the bottom of the habitat.
- Animal care support: feeding fish and other animals under staff direction, and watching for changes in behavior or condition that staff should know about.
- Guest presentations: many aquariums run live dive shows where a volunteer in the tank talks to visitors, sometimes through a full face mask with a communication system.
- Behind-the-scenes support: rinsing, organizing, and caring for dive equipment, and logging each dive.
Some programs go further. The Florida Aquarium, for example, describes its dive volunteers helping with environmental stewardship projects outside the building, including marine debris removal, in addition to habitat maintenance on site.
Typical requirements for aquarium volunteer divers
Every program sets its own standards, and they change from year to year, so always read the current listing for the aquarium near you. That said, the requirements tend to look alike. Here's what several well-known U.S. programs listed on their volunteer pages at the time of writing:
| Aquarium | Minimum age | Certification and experience | Commitment |
|---|---|---|---|
| Aquarium of the Pacific (Long Beach, CA) | 18 | Rescue Diver, 50 logged dives, plus First Aid, CPR, AED, and O2 provider | One dive a week for at least a year |
| Monterey Bay Aquarium (Monterey, CA) | 18 | Open Water, Advanced, and Rescue; 20 cold-water dives in the last five years; CPR, First Aid, AED, and O2 | One year, with a shift every other week |
| Seattle Aquarium (Seattle, WA) | 18 | Advanced Open Water, 50 lifetime dives, 12 local dives in the last 12 months | One three-hour shift every other week for a year |
| Tennessee Aquarium (Chattanooga, TN) | 18 | 25 logged dives after certification, 12 open water dives in the last three years; First Aid, CPR, and O2 provider | One seven-hour shift every four weeks |
| The Florida Aquarium (Tampa, FL) | 18 | Open Water with 25+ open water dives; AAUS dive physical and swim test | One year |
| New York Aquarium (Brooklyn, NY) | 21 | Certified diver (Rescue preferred), 25 logged dives with 3 in the last 12 months | One full-day shift every other week for a year |
A few patterns stand out. You need to be an adult. Most programs want somewhere between 25 and 50 logged dives, and several want proof that you've been diving recently, not just at some point. Rescue Diver certification is required or preferred at a number of aquariums, and emergency care training (CPR, First Aid, and often oxygen provider) comes up again and again. And nearly every program asks for at least a one-year commitment, because training a new volunteer takes real staff time.
Medical and fitness standards
Expect a more thorough medical screening than you had for your Open Water course. Programs commonly require a dive physical signed by a physician, and some follow scientific diving standards set by the American Academy of Underwater Sciences (AAUS). Monterey Bay Aquarium describes its requirement as an occupational diving physical. Some programs renew the physical every year.
Many also include a swim test. Aquarium of the Pacific, for example, lists a 400-yard swim in 12 minutes or less and a 10-minute tread, along with the ability to lift and carry up to 50 pounds. If you haven't swum laps in a while, start now. It's the part of the checkout that catches the most applicants off guard.
Your dive log matters
Aquariums verify experience, so your log needs to be complete and readable. New York Aquarium asks applicants for the last 25 pages of their dive log, and Seattle Aquarium asks for a current log. If your dives live in a shoebox of half-filled paper pages, or in your memory, take an evening to get them organized before you apply.
This is one place where a dive computer that syncs to an app earns its keep. The Garmin Descent G2 records every dive automatically and pairs with the Garmin Dive app, so your depth, time, and site history are stored and easy to share when a program asks for proof of recent diving.

How the application and checkout usually work
The details vary, but most programs follow a similar path from application to your first shift in a habitat:
- Watch for openings. Many aquariums only accept dive volunteer applications at certain times of year, and some keep an interest list. The Tennessee Aquarium's page, for example, noted its applications were closed and scheduled to reopen on November 2, 2026. If your local program is closed, join the notification list and use the time to meet the requirements.
- Submit your application and documents. Expect to provide copies of your certification cards, your emergency care certifications, and your dive log. Some programs also run a background check.
- Attend an orientation. This is where you learn how the program runs, what shifts are available, and what the aquarium expects from its volunteers.
- Pass written and in-water evaluations. Knowledge reviews often cover dive physics, physiology, equipment, and emergency procedures. Monterey Bay Aquarium lists an 80 percent minimum score. The in-water part is usually a swim test plus a scuba skills checkout.
- Complete habitat and specialty training. Before your first exhibit dive, you'll learn the layout of each habitat, how to work around the animals, and any specialized equipment. Seattle Aquarium, for instance, requires full face mask training before habitat diving.
Treat the skills checkout like an exam you want to ace, not one you hope to scrape through. Staff are looking for calm, controlled divers who hold their position without kicking up sand or touching anything they shouldn't. Precise buoyancy is the single most valuable skill you can bring.
What gear you may need to bring
This is the part that varies most between programs. Aquarium of the Pacific provides full wetsuits, booties, gloves, and hoods, and The Florida Aquarium says most diving equipment is provided. Other programs expect you to bring more of your own:
- Monterey Bay Aquarium asks volunteers to provide their own mask, weights, and thermal protection, and inspects all equipment before use.
- Seattle Aquarium asks applicants to bring a full set of gear for the checkout dive: cylinder, BCD, regulator with an alternate air source, mask, fins, snorkel, compass, depth gauge or computer, exposure protection, and weights. Active volunteers in its cold-water habitats supply their own exposure suits, fins, and a timing device.
Even where the aquarium supplies most equipment, a mask that fits your face and exposure protection that fits your body make a big difference over a year of shifts. Check the dive masks collection if your current mask leaks or fogs, because you'll be spending a lot of time looking through it at very close range.
Thermal protection for long shifts
Aquarium water isn't always warm. Aquarium of the Pacific lists habitat temperatures from 58 to 74°F, and cold-water exhibits like kelp forests can be cooler still. A maintenance dive also tends to be slow and stationary, which chills you faster than a fun dive where you're finning along a reef. If your program asks you to bring your own suit, choose one for the coldest habitat you'll work in, and consider a hood from our hoods and vests collection.
The Hollis Neotek 4/3 is one of our best-selling full suits and a practical choice for temperate water. It has a front zipper, Hollis's ThermaSkin liner, and thigh pockets that are handy for a slate or small cleaning tools.

An alternate air source for your own rig
If your program asks you to bring a complete scuba setup for the checkout, your regulator needs an alternate air source. If yours is missing one, or the octopus you have is old and hasn't been serviced, the Scubapro R105 Octopus is a dependable option that many of our customers choose.
Scubapro R105 Octopus Regulator – Reliable Backup for Scuba Diving
A backup second stage with a metal valve housing for cold-water durability, a high-visibility yellow faceplate and 39-inch hose, and a reversible hose connection for left- or right-hand setups.

Before any checkout, get your regulator and BCD serviced if they're due. An evaluator who sees a free-flowing second stage or a sticky inflator will notice, and it's an easy problem to avoid.
How to make yourself a strong applicant
Dive volunteer spots can be competitive, especially at large aquariums. Here's what we'd tell any club member who wants to get in:
- Close the certification gap early. If the program near you wants Rescue Diver, sign up for the course now rather than waiting for applications to open. Get your CPR, First Aid, and oxygen provider cards current at the same time.
- Dive locally and recently. Several programs care about recent dives in local conditions. Joining regular club dives is the easiest way to build those numbers. Our guide to finding and joining a local dive club can help you get started.
- Polish your buoyancy. Practice hovering motionless, holding a fixed position while using your hands for a task, and moving slowly with minimal fin movement. That's the job.
- Get comfortable talking to people. Many aquarium divers interact with visitors through the glass or during live presentations. Friendly, patient people who enjoy explaining marine life tend to thrive.
- Be honest about your schedule. A one-year commitment with regular attendance is the norm. Aquarium of the Pacific, for instance, asks for at least 75 percent annual attendance. Only apply if you can keep the shift.
If you're returning to diving after some time away, start with a refresher before you apply. Our guide to getting back into scuba diving after a break walks through how to rebuild your skills and confidence.
Other ways to volunteer as a diver
Not every town has an aquarium with a dive program, and openings can be limited. If the timing isn't right, there are plenty of other ways to put your diving to work for the ocean and your community. You can join or organize a community cleanup dive, or take part in reef surveys and other citizen science programs open to any certified diver. These are also a great way to build the recent, documented dive experience that aquarium programs look for.
Quick answers to common questions
Do aquarium volunteer divers get paid?
No. These are unpaid volunteer roles. Some programs cover costs such as the dive physical (Monterey Bay Aquarium lists this), and most provide some or all of the dive equipment and air, but the position itself is volunteer work.
Can I volunteer if I'm only Open Water certified?
Sometimes. The Florida Aquarium lists Open Water certification with 25 or more open water dives, and the Tennessee Aquarium asks for certification from a recognized agency plus a set number of logged dives. Other programs, like Monterey Bay Aquarium and Aquarium of the Pacific, require Rescue Diver. Check the current listing for the program you're interested in.
Do I need my own dive gear?
It depends on the aquarium. Some provide nearly everything, while others ask you to bring a mask, weights, exposure protection, or a full rig for your checkout. Read the program's equipment list carefully before your checkout day.
How much time does it take?
Most programs ask for a shift every one to four weeks for at least a year, plus several training sessions at the start. Shifts commonly run from a few hours to a full day.
Aquarium diving is one of the most rewarding ways to stay in the water between trips, keep your skills sharp, and become part of a dedicated community of divers. Find the program nearest you, check its current requirements, and start working toward them. When you're ready to fill gaps in your kit, browse our wetsuits, dive computers, and regulators, and we'll see you on the other side of the glass.
