Snorkeling with Humpback Whales in Tonga

We’d spent more than six incredible hours snorkeling with two adult humpback whales in Tonga. Every time we returned to the boat, the two whales began breaching out of the water, as if they were desperate to see what we were doing. We quickly jumped back in, so as not to offend them. We floated in amazement as the two humpbacks twisted and danced below us, impressing us with their show. After snorkeling with humpback whales in Tonga, my world forever changed. I fell in love and fell hard.

My love affair with humpbacks began in 2008 when I stumbled on some crystal-clear pictures of the whales, taken in the Tongan Islands. I spent the next few years dreaming of a Tongan encounter of my own. There are only a few places in the world where it’s possible to get in the water with them, so in the meantime, I visited both the Silver Banks in the Dominican Republic and Cabo San Lucas in Mexico to snorkel with humpbacks. Although both experiences were worthwhile, I came away without any memorable encounters or thrilling photos. I finally set my sights on Tonga in 2014.

From my very first trip, the experiences didn’t disappoint. I spent over a month interacting with the humpbacks and, to my surprise, got in the water with them every day I went out. The water was clear; the humpbacks were gentle; and the experience was beyond amazing. As someone who spends roughly 300 days a year in or on the water, snorkeling with humpback whales in Tonga is and always will be the best ocean experience of my life. Watching a 40-ton humpback whale dancing and twirling in front of you, or simply floating next to one while it stares at you is incredible. Snorkeling with humpback whales in Tonga is such a singular experience that I began running guided trips there every year, to show other ocean lovers just how amazing these animals are.

Where is Tonga?

The most complicated part of snorkeling with humpbacks in Tonga might be just getting there. The island of Vava’u, Tonga is near Fiji but far off the radar for most people. You must fly via Fiji, Sydney or Auckland — you can’t get there any other way. From one of these hubs, you can either fly to Tongatapu International (TBU) and take a domestic flight to Vava’u or fly direct from Fiji to Vava’u. The latter option is limited to twice-a-week flights however, and they aren’t especially reliable.

An aerial overview of some swimmers with three humpback whales. The mom and calf in front, with singer/escort behind. A freediver friend, Hylton, was slightly below the surface with one of the most playful adult whales I’ve ever seen. This particular encounter took up most of the day! A mom, calf and very playful escort with one of our clients. This encounter was out in the blue, and the entire group of whales played with us for hours. A shallow-water heat run, wherein males chase a female, vying for the opportunity to mate with her. There were more than 12 humpback whales in this particular run, chasing after one female.

What brings the whales to Tonga?

From late July to late October, the whales come to Tonga to mate and give birth. Adult females give birth to a new calf every two years, after a pregnancy that lasts 11 months. A female will nurse her calf for about a year before letting it venture into the open ocean alone. Calves are born in Tongan waters every year, and they enter the world weighing around one ton (900 kg).

What is snorkeling with humpback whales in Tonga like?

Our boats leave at 7 a.m. sharp so that we can be the first ones out on the water. With only about 15 other boats covering 300 square nautical miles, we rarely see them. We might find whales right away, although it can take hours. When we do spot whales, we’ll first observe them and the crew will decide if we can jump in the water with them or not. Some whales are playful right away; some take time to warm up.

Hylton yet again, with the very playful whale. A mom and calf humpback whale, floating in the shallow reefs off Vava’u. One of my clients having the time of her life with a mom and calf humpback whale. Encounters like these are very common. Two adult humpback whales, playing in the waters off Vava’u, Tonga. You can often find them playing, pecking and tail slapping. An adult humpback whale breaching right in front of our boat! You can really get a sense of their power in this image as 40 tons of animal flies out of the ocean.

We never know what we’ll see — anything from a lone juvenile who’s recently left its mother to 15 whales chasing a female in an energetic heat run. Sometimes a curious calf will roll and play with its mom, staying with us for hours. Early on in the season, the moms are a bit more protective of their new offspring. But later on, when the calves are older, they tend to be more interactive with tourists. They are wild animals of course, so you never know what you’ll get. You might also witness a heat run, when a group of male whales chases after a female whale in heat. From five or six whales up to as many as 20 may roam the waters below you, following the female. Every day is different, and every encounter is different, lasting anywhere from five to 90 minutes.

Only five people — four snorkelers and a guide — can enter the water at once, which keeps the groups small. This also allows the guide to keep an eye on the swimmers. Although some people hypothesize that the whales don’t like swimming with humans, a 40-ton animal can easily leave a situation with a flick of its tail. You can see in the video that they are indeed quite interested, playful and very joyful.

Our boats try not only to be the first ones in the water, but also the last ones out of the water. We decide as a group when the day is over, which could be at 2 p.m. or could be at 5 p.m. We work with the crew and base our decision on how well the day went.

Snorkeling with humpbacks in Tonga is truly a once-in-a-lifetime experience. We’d love for you to join us next year; check out our trips here.

SeaLife Introduces New Sea Dragon 2300 Auto Photo-Video-Dive Light

SeaLife is excited to introduce the new Sea Dragon 2300 Auto Photo-Video-Dive light at the upcoming DEMA (Dive Equipment & Marketing Association) tradeshow. The 2300 Auto features 2300 true lumens of brightness and an ideal color-temperature ranging between 5000k and 6000k, with a wide 100-degree beam angle. The new Sea Dragon 2300 Auto also offers two unique features, Auto Brightness Mode and Auto Flash Detect Mode, to enhance your underwater diving and imaging experience.

SeaLife DC1400

With the 2300 Auto’s built-in photocell sensor, the Auto Bright Mode automatically dims the light from 100 percent to 10 percent, depending on distance. This will preserve your eyes’ natural low-light vision and also the battery life. From the four brightness options, simply select the Auto feature and the light will regulate brightness based on proximity between the light and the object. If pointed at a close range like a gauge or a computer, the light will dim to a 10 percent brightness, and when directing the light long-distance it will automatically adjust the light to full power. This feature can be easily over-ridden by selecting a different brightness option of 100 percent, 50 percent, or 25 percent.

The Sea Dragon 2300 Auto also includes Auto Flash Detect Mode for underwater still-image photographers, which turns the light off for two seconds when an external flash is detected to eliminate undesirable shadows, color shifts and backscatter.

SeaLife DC1400

Powered by a rechargeable 7.4 lithium-ion battery, the light burns for a full hour at constant brightness and full power with its new 6x CREE XP-L LEDs, and can quickly adjust between four brightness options: 100 percent, 50 percent, or 25 percent, and Auto with its single button operation.

The Sea Dragon 2300 Auto is depth-rated to 330 feet (100 m) . The dual O-ring battery compartment is completely sealed and independent from the Sea Dragon’s electronics, so the light will not be compromised if there is accidental water intrusion.

Similar to all Sea Dragon Photo/Video/Dive Lights, the 2300 Auto can easily be expanded with Flex-Connect Arms, Grips, and Trays. Sea Dragon lights are universal and can be easily mounted to any camera or arm system using an optional Flex-Connect ball mount adapter (SL995). SeaLife also offers a cold shoe mount for the Sea Dragon (SL991). SeaLife also offers a handle for handheld use (SL998).

What to Do if You’re Caught in an Upcurrent

As outlined in a previous article, suddenly finding yourself dragged deeper by a downcurrent can be an intimidating experience during any dive. But finding yourself caught in an upcurrent can be just as scary. Any dive spot that is known for having strong currents may also potentially create down and upcurrents. We’ve already discussed what you should do in a downcurrent, but how should you react to an upcurrent? Here are five tips to help get you out of trouble if you’re caught in an upcurrent.

  1. Listen to your dive briefing. I can’t overemphasize how important this is before any dive, especially at a site known for currents. The person giving the briefing is a full-time dive professional, who knows the dive site and the conditions far better than you do. Not listening is at best rude, and at worst dangerous, no matter how experienced you think you are or how tame the conditions appear to be.Sites like walls are much more likely to experience upcurrents, so pay attention when your dive leader and boat captain explain procedures. When diving, if you’ve got a divemaster, follow his or her lead. Watch for warning signs yourself during a dive, such as fish swimming erratically or vertically up or down, or divers’ exhalation suddenly going up much faster than normal. If you notice your own bubbles doing this, it may be too late.
  1. While you might be able to grab onto something to slow or stop your ascent (don’t touch coral if you can help it), doing so will keep you in the upcurrent’s path. Don’t rely on thinking that you can wait it out. Instead, empty all the air from of your BCD and swim downward at a 45-degree angle, horizontally away from the current. Swimming directly down against the current will just exhaust you and keep you in the firing line, just as trying to swim straight up in a downcurrent is futile. Remember that although these currents can be very strong, up to four knots, they are usually also very narrow, just like a rip current. So eventually you will come out of it.
  1. Try to stay calm — easier said than done I know, but anxiety can quickly turn to panic, and panicked is the last thing you want to be underwater. Remember to keep breathing throughout. Inadvertently holding your breath on ascent can lead to a pulmonary barotrauma.
  1. If, despite emptying your BCD and trying to swim downward horizontally out of the current, you still find yourself ascending too fast and nearing the surface, flare your body to try and increase your drag on the water. If you do surface, do not attempt to descend again. Instead, signal your boat that you require assistance by either waving both arms above your head or by holding a DSMB above your head if you can. If you have a whistle, use it. As soon as the boat is close enough, tell them that you had a rapid ascent, answer their questions and follow their instructions once on board. They may just monitor you, watching for signs of DCS, or you may breathe oxygen as a precaution, followed by a check-up with a physician.
  1. Build up your experience. If you’ve just completed your open-water course in calm conditions, don’t choose dive locations known for strong currents. Practice your skills in order to become more comfortable with buoyancy and diving procedures. Once you’ve logged more dives, you’ll be able to explore advanced sites with more confidence.

Conservation Group Considers Nova Scotia for SeaWorld Whale Sanctuary

In March 2016, SeaWorld announced that it was ending its captive-orca breeding program. Conservationists and animal-rights activists were jubilant at the news.  Some, however, criticized the company’s decision to keep its 23 remaining U.S. orcas in captivity for the remainder of their lives. However, all of SeaWorld’s whales were either born in captivity or have spent most of their lives in a tank. As such, they rely humans for food. They have lost (or never learned) many of the instincts that they need in order to survive in the wild. Releasing them into the ocean is therefore irresponsible, but is there an alternative? Conservationists hope a potential SeaWorld whale sanctuary could be the answer.

Marine sanctuaries could be a good compromise. These environments would allow the whales some freedom while humans still care for them as necessary. While there are sanctuaries for other large animals, such as elephants, lions and apes, there are currently no such facilities for cetaceans. U.S. based non-profit The Whale Sanctuary Project is hoping to remedy this deficiency. In August a team headed by charity president Dr. Lori Marino traveled to Nova Scotia to assess potential sanctuary sites.

The Whale Sanctuary Project

The Whale Sanctuary Project was born in August 2015. A group of experts, including marine biologists, veterinarians and engineers, met to discuss a possible sanctuary for whales like those that SeaWorld has retired. A year later, the group established the project as a licensed non-profit. Today, executive director of the Kimmela Center for Animal Advocacy Dr. Lori Marino, marine mammal scientist Dr. Naomi Rose; and David Phillips, director of the International Marine Mammal Project, spearhead the project.

Earlier this year, baby-product manufacturer Munchkin, Inc. gave the Whale Sanctuary Project $200,000. The company has pledged a total of $1 million toward the sanctuary’s completion. The project will use this initial donation to research a suitable site for the sanctuary, which must fulfill several criteria. The site must be large enough to mimic the natural habitat of the rehabilitated whales and dolphins. It must be possible to separate the sanctuary from open ocean. Finally, adjacent communities must be receptive for the sanctuary’s success.

Why Nova Scotia?

The group selected Nova Scotia as a potential site because of its plentiful coves, bays and inlets. Some of these are too shallow to provide the required space, however. The organization must conduct further investigation before confirming a suitable site. The Whale Sanctuary Project will visit other regions over the coming months, searching for the perfect cove. Contenders include Maine, Washington State and British Columbia. However, according to a company press release, officials in Nova Scotia are excited about the possibility of the sanctuary.

Regardless of the ultimate location, the Whale Sanctuary Project’s vision remains the same. Once completed, the sanctuary will become a safe haven for cold-water cetacean species, including orcas and belugas. The sanctuary will welcome whales, dolphins and porpoises, and the group will try to return successfully rehabilitated individuals to the wild. Captive-bred whales and dolphins may never be fit for release, however, and will instead receive care for the rest of their lives.

Administrators will allow the public to visit the whale sanctuary as long as such visits don’t interfere with or disturb the animals. The sanctuary will focus on conservation and education instead of entertainment, offering the whales a much-deserved retirement from the public eye.
