Breaching Humpback Whales! 2/21/08

Wow, it’s been a while, hasn’t it? Hopefully my blog readers haven’t completely forgotten me! Part of the reason for the gap is that Masa got a new boat, so we had some down time between saying goodbye to the old boat and getting the new one shipped over from Oahu. Masa felt pretty sad about seeing his old friend go, a boat on which he’s had many memories and taken so many amazing, award-winning shots.

Once he got the new boat, though, a nice twin-engine, catamaran style Glacier Bay, we were out almost every day, testing the equipment and checking out the wildlife. We’ve been so busy out on the water, that I haven’t had much time to write it all down. Finally, though, I’ve managed to process some great new humpback whales shots and create this blog entry.

On Feb. 21, Masa, me, and Steve Drogin were out on the water for a full day of whale watching. I wrote about Steve in my blog called Dinner with Some Giants in the Industry 11/30/07. He’s one of our SeaPics.com photographers, and he has many great images of sharks, rays, monk seals and more on our site. Check them out if you have a chance.

Anyway, Steve was with us, enjoying Masa’s new boat and checking out the humpback whales. The whales were incredible that day, breaching all around us. It was really a photographer’s dream. Most days are not like this, as it’s not possible to predict where and when a whale will breach, so you have to be vigilant and a little lucky to get a great shot. On this day, though, getting the money shot was like rolling over in bed. The light was great and the whales kept breaching over and over, so we could position ourselves perfectly and get the shots we wanted.

One of the great things about living in Hawaii is being able to see these amazing humpback whale breaches. If you live on the west coast of the U.S., you may be able to see gray whales (Eschrichtius robustus), but they aren’t known for the breaches and other above water activities performed by the humpbacks (Megaptera novaeangliae).

The playful behavior of humpback whales is well known and has even been mentioned in classic American literature. Herman Melville, using the character Ishmael as his narrator in Moby-Dick, said of the humpbacks that they are "the most gamesome of species and light-hearted of all the whales, making more gay foam and white water than any other."

He certainly got that right. Humpbacks must think they’re dolphins, a distant relative, though they’re at least 110 times heavier. They launch themselves out of the water, nearly clearing it, and flop onto the surface, usually on their back or side, creating a minor tsunami for nearby boats. They’re also known for tail slapping, pec slapping, peduncle throws, spy hopping and other behaviors.

Here’s a quick glossary of humpback whale behaviors, with links to images of the behavior on our SeaPics.com site:

breach – the whale launches most of its body out of the water and crashes onto the surface

lunge – a shallow breach where a male lunges aggressively towards a competitor

tail slap – the whale, with its body nearly vertical, facing down, slaps its tail repeatedly onto the surface of the water

pec slap – the whale, lying on its side, slaps its pectoral fin repeatedly against the surface of the water

peduncle throw – a powerful spin move where the whale thrusts its tail and lower body area across the surface of the water, throwing up a big spray

spy hop – the whale, curious about activity above the surface, assumes a vertical position with it’s head and eye above water so it can view the whale watchers!

Why do they do these behaviors? While we can’t interpret each behavior precisely, many of the slapping and lunging behaviors are presumed to be competitive displays by males, used to signal each other as they vie for the attention of females. Breaching, however, is performed by whales of both sexes and all ages, whether they’re alone or with others. It may have the practical use of shaking off barnacles, or it may be that the whales just like the sensation of leaving the water and crashing onto the surface. The image above left is of a peduncle throw.

For me, personally, this was one of my best days ever for humpback whale photography. The reason for my confidence is that Steve Drogin lent me his telephoto lens, as he was trying out another one. For the first time, I was able to use an 80-400 vibration reduction lens, which made a huge difference in the kind of shots I could get.

Normally, when I’m out on the boat with Masa, his shots are always so much better than mine. Masa uses a 70-200/2.8 L Canon with a teleconverter, which makes it more than twice as powerful as the lens I own. At the safe distance we must maintain from the whales, his whale shots have always filled the frame and been beautifully in focus, while mine have been way too small. On this day, though, with Steve’s great lens, my shots were nearly filling the frame! The light was great, and the whales breached straight in front of us, over and over. At least on this occasion, my breaching whale shots are good enough to post on my blog. I still can’t compete with the world class photographers I represent at SeaPics.com, but I was really stoked to get some decent shots, as those of you who take photos for enjoyment can readily understand! Thanks, Steve, for the assist!

That’s it for now, but I’ll have another blog up soon about more humpback whale excursions. I expect you’ll see that in a week or so.

Close Encounters with Wyland the Artist, Part II 12/29/07

After a marathon day with Wyland, the Artist, where we boated, swam and snorkeled all day, followed by an artist's reception at Wyland Galleries in the evening, Wyland was up and ready for more the next day! Wyland is a machine!

It appeared his gallery reception had gone well, and Masa and I had a good time, too. Besides the awesome original Wyland art we received (see Wyland Part I blog 12/28), we had met Dean Burnell, the Dolphin Whisperer. Dean was famous for his work with dolphins in the Turks & Caicos, where he used to live. For years, I had been selling our SeaPics.com photos of him with JoJo, the sociable Atlantic bottlenose dolphin (that's Dean & Jojo in photo above at left), and suddenly, here he was in Kona, where he now resides! What an amazing coincidence! Masa, Dean & Wyland are in the photo below right.

Dean's story of why he no longer lives in the Turks & Caicos, and how he ended up in Kona, Hawaii is a little long and personal, so I won't go into detail. I will say, however, that the story involves a stopover in Crete, where sirens sing to you and cure whatever ails you. Enough about that, and on to our adventures with Wyland!

It was Saturday morning, the 29th, and we still wanted to see humpback whales, so we headed north. If you come to Big Island, Hawaii during whale season, which is December to March, you'll usually find humpbacks north of the Kona airport, especially up in the Kohala region. Humpback whales breed here in winter after their long migration from Alaska.

As we headed north, Wyland said he wanted to stop and check out Turtle Pinnacle, one of Kona's better known dive sites. SeaPics.com has many photos of green sea turtles being cleaned by yellow tang and other reef fish, and most of them are from this spot. We have so many of these nice shots that divers visiting Kona tend to think sea turtles are always getting cleaned somewhere, waiting to be photographed. Well, the key to getting these great shots is to be at Turtle Pinnacle, a time-honored cleaning station. If you look for this anywhere else, you'll likely be disappointed.

The water was kind of rough, but we stopped at Turtle Pinnacle for Wyland to work his magic and find some sea turtles. Strangely, though, it didn't happen. We searched for sea turtles for about 45 minutes, but never found any. Hmm, it seemed the Wyland magic was wearing off!

We continued north, convinced we'd see some spinner dolphins around the airport. Nada. We wondered where all the marine life had gone.

As we searched the area, we stumbled upon a huge fishing net drifting in the ocean. The net was so large, we couldn't even attempt to retrieve it. Like an iceberg, the tip of it was at the surface, and the rest of it hung down, down, down, fading into the blue.

A drifting net like this is certainly a danger to marine life. On the other hand, it's also a refuge for thousands of other species. There were countless fish using this net as a floating reef, as were the sea plants and tiny crustaceans attached to it. Wyland got in the water and videotaped the net. He said he got some great footage, though I doubt we'll be seeing it on any of his music DVDs!

After Wyland got back in the boat, I spotted a whale breaching. Wyland was eager to go see if we could get some photos of it, but Masa was thinking he wanted to get in the water and photograph the net. Wyland suggested we leave Masa at the net, check out the whales, and then come back for Masa later. Strangely, Masa was not eager to go along with this plan. It seems being left drifting with a net in the middle of the ocean was not Masa's idea of a good way to spend the day. I admit, I could see the logic in his reasoning. Wyland promised we'd quickly return to the net, but we thought it better to all depart together to look for the whales, which is what we did.

Well, the Wyland magic was definitely on hiatus, as we didn't saw a humpback whale the rest of the day. After looking long and hard, we decided to go back to the floating net and do some fishing. But now that net was playing hard-to-find. We went up and down the coast, looking for it. It's a really good thing we didn't leave Masa out there, drifting with the net, as we might never have found him again!

Finally, we spotted it and Masa dropped a line and caught a mahi mahi right away. When you catch a mahi mahi, it's common to leave the first one on the hook for a while, as strangely, the other mahi mahi will congregate around it. This happened in textbook fashion, and within minutes we had our second mahi mahi.

We thought Wyland should get in and photograph the mahi mahi on the lines, but he was reluctant to do so, as his brand is built around live animals and preserving the environment. We convinced hims that someday he'd need visual reference of fish like this on a line, perhaps for an overfishing campaign or the like, and he went in for some photos. But I could see his heart wasn't into it.

Wyland was back on the boat pretty quickly after that. We caught two more mahi mahi and packed it in for the day. We headed south to try Turtle Pinnacle one more time. We swam and snorkeled around there for at least an hour, but never did see a turtle. Too bad for Wyland; at least we live here, so we'll see the turtles another day!

Dinner with Some Giants in the Industry 11/30/07

Most of my blog entries so far have been about our activities on the water with fish and marine mammals, but today I'm going to write about how I spend some of my free moments on dry land with the two-legged critters. Masa and I were invited to a dinner party at the Kona home of our friend, Steve Drogin, who is also one of our SeaPics.com photographers. He and his wife, Hiro, reside in La Jolla, California, but they have a lovely house here on the Big Island, which they visit between boating excursions around the world.

Steve Drogin is first and foremost, a fantastic photographer, and SeaPics.com has over 300 of his images in our database. His work has been featured in BBC productions, the Discovery Channel, Disney's Living Seas, as well as in countless books and dive magazines. He is also an environmentalist, and he gives lectures on marine life and the environment around the world. Besides this image of blue sharks, SeaPics.com has great photos from Steve of manta rays, Hawaiian monk seals, nudibranches, and more. Click this link–Steve Drogin pix-to see all of his amazing photos on our site.

Steve was in town after a visit to Easter Island. Before that, he had been in Costa Rica at Cocos Island, where he actually has a submarine that can take passengers to depths of 1,500 feet. Now many of us dream of having a nice boat to cruise the world, but Steve has his own submarine! Of course, it's a commercial operation, so he doesn't really have unlimited use of it, but still… What undersea photographer wouldn't love to have their own submarine? Anyway, if you are ever interested in going 457 meters deep off the coast of Cocos Island, and you've got about $2,500 to spare for a ticket, then consider the Deep See excursion. Prices actually start at about US $600 for a 100-meter dive. Check out the Deep See website here for more details. And no, I'm not getting a cut of the sales; this is just a friendly link to a friend's site! The sub photo, by the way, was taken by Steven's friend, Mark Conlin, a SeaPics.com photographer with nearly 1,800 images in our database (see Mark Conlin pix).

While at Steve's dinner party, we had the opportunity to meet Bob Talbot, another well-known person in photography and film. He's a world-renowned marine photographer and an award-winning film-maker. His film credits include "Free Willy," "Flipper" (1996), the Imax motion simulation film "Dolphins-the Ride," and most recently, Imax's "Oceanmen-Extreme Dive." For those of you who don't read film credits, you may be familiar with Bob Talbot from his iconic images of marine life and seascapes that have appeared in posters throughout the world.

Talking to Bob that night was fascinating, as he's a true visionary in future environmentalism, and he's committed himself to ending our destructive treatment of the planet. One of the reasons he's in Hawaii is because he's shooting in the Northwest Hawaiian islands for a film project on the health of the oceans. According to Bob, this will be a kind of "Inconvenient Truth" about the marine environment, and I'm really looking forward to seeing it. To learn more about Bob and his activities, visit his website at the Talbot Collection.

Besides Bob Talbot (center) in this photo, there are some other people of note. Masa, the SeaPics.com photographer and tech expert, who appears in every fishing excursion blog with me, is there, center left (see Masa Ushioda pix). And on the right are Carlos Eyles and his wife Margaret. Carlos is another amazing SeaPics.com photographer (see Carlos Eyles pix). His photos are notable for their artistic composition and the amazing underside angles he often gets. Carlos and his wife are both excellent freedivers, and they can swim below the animals and look up to see them silhouetted against the surface. Amazing, the depths they can reach and the unique shots Carlos can get. Margaret is famous in Kona for being a rolfing therapist, and Carlos is an accomplished author. Finally, that's me, Kona Sue, on the left. You didn't actually think I was a green fish, like in my profile photo, did you? Well now the secret's out!

Are you all tired of me name-dropping yet? Well, you'll have to bear with me, as an upcoming blog will be about Wyland, the artist, who was in town recently, and who went out on the boat with Masa and me. Watch for that soon!

Tagging Green Sea Turtles on the Kona Coast - Nov. 28, 2007

Between mechanical problems with Masa's boat and the unwillingness of Kona's marine life to cooperate, I haven't been able to get many compelling photos lately. Thankfully, an interesting land event took place that filled the gap – sea turtle tagging at the beach in Kaloko-Honokohau National Park!

At SeaPics.com, I'm in a good position to learn about events and happenings related to the ocean and marine life. My photographers, who are out on the water on a daily basis, usually keep me informed. On this day, however, it was my staff, Christine and Lynn, who told me about the sea turtle tagging. They told me they needed the morning off to help further the cause of green sea turtle research. And since this event also provided a great photo opportunity, we all abandoned the office for a close-up look of Big Island's honu (Hawaiian for green sea turtle).

Down at the beach at Kaloko-Honokohau National Park, near the Honokohau Marina, a large tent was set up for the all-day tagging event. George Balazs, a prominent sea turtle researcher with the National Marine Fisheries Service (he was largely responsible for getting the green sea turtle listed as an endangered species), and Marc Rice, a teacher at Hawaii Preparatory Academy were in charge. They were being assisted by students from HPA, and by a few specially chosen volunteers, including Christine and Lynn, my two SeaPics.com employees. Christine and Lynn were able to participate because of their work with ReefTeach, a volunteer group on the Big Island. It is due to their efforts that the Reef Teachers were educated on sea turtles and now pass that information on to visitors at Kahulu'u Beach Park.

The procedure was for a group of researchers and student volunteers to go out with nets and large inner tubes to find sea turtles on the beach and in the shallows. Once found, the turtles are carefully placed into the inner tube, which has an attached bottom, then transferred to a crate on the beach for weighing.

After weighing, each turtle is placed on a table for examination by George Balazs. The turtles are examined for injuries, disease and parasites, and they are all scanned for microchips which may have been inserted into the turtle's flipper at a previous tagging event. If no microchip is found, one is inserted. If they have a sonic transmitter attached to the shell, this is also scanned. George then measures and records the turtle's length, width and girth. The purpose of all of this is to help researchers understand the general condition of the turtles, and to see whether they are growing well and getting enough food.

Before releasing the turtles back into the water, a number is inscribed onto the shell and then painted over with white paint. There are several purposes for this number. One is to provide an easy way for observers to identify the turtle in the wild. Park staff at the Kaloko-Honokohau National Park record when certain turtles are seen at particular points on the park beach, which helps researchers to understand their behavior. Another reason for the numbers is to ensure that the researchers don't continually recapture the same sea turtle during the tagging. The white paint tends to become less visible over time, as algae accumulates on the turtle shell, but there is no harmful effect on the turtle.

After all data is recorded, the turtles are released back into the ocean. Some hurry off to deeper water, while others appear content to linger. Sea turtles are not used to being handled (it's actually illegal in Hawaii for people to touch them, with the exception of this research effort) so I'm sure they were happy to be on their way.

I have lived in Kona, Hawaii for 12 years, and seen hundreds of sea turtles. To see them up close like this, and to learn about the turtle tagging effort, was a unique and valuable experience. Sea turtles are one of the symbols of Hawaii, and it's important for this type of research to take place. Sea turtles are endangered the world over (you can see the IUCN status on our SeaPics.com database). Numbers are generally increasing in Hawaii, but this poses new problems of turtles and humans competing for the same patch of sand. Thanks to the efforts of the National Marine Fisheries Service, the HPA students, and ReefTeach volunteers Lynn & Christine, Hawaiian green sea turtles stand a better chance of making it through to the next century!

A special thanks to researcher George Balazs, who was kind enough to invite Lynn & Christine, and who was so informative about the sea turtle tagging. There is not one person on the beach that day who didn't come away with more knowledge and appreciation of sea turtles!

To Retrieve or Not to Retrieve Floating Trash - Nov. 9, 2007

We left the boat launch at 10:45 and headed out to the FADs (Fish Aggregation Devices), as we usually do, but we hadn't even left Keauhou Bay when we came across a huge baitball of akule (bigeye scad). Masa jumped into the water to get some photos, as shots of swirling bait can be beautiful in the right light. He was in the water for 10 minutes or so, got some pics and then we continued on.

There was a pod of long-snouted spinner dolphins near us for while, but they seemed unwilling to ride our wake, like they often do. No notable pics as a result of their standoffishness.

At one point, two large mahi mahi circled our boat and investigated Masa's lure. One of them grabbed it just underneath the boat, and leaped 15 feet out of the water! It's always exciting when a mahi mahi takes your lure and leaps so high up - the very behavior that led them to be called dolphin fish! That long, green fish ended up breaking off the hook, and making a clean get-away. It's odd that he managed to break off the hook, as it was on a 60lb wire leader, so we speculated on what other toothy fish (wahoo, barracuda or shark) was down there that may have done the job before him. We hung there for a while, but came up empty.

About 300 feet or so from VV buoy, we came across some trash in the water. It was a piece of floating styrofoam, and my readers, I know you're thinking, "Of course, you retrieved the trash in the interest of protecting marine life." Well, in this case, you'd be wrong! And since there is little else to talk about for today's blog, I'm going to pontificate on trash.

There is all kinds of trash in the ocean. Floating plastic can be a danger to sea turtles, as they ingest it, thinking it to be edible, like jellyfish or squid. There are discarded fishing nets that can get wrapped around seals, whales and dolphins, and of course, no marine animal will last long with synthetic nylon cords constricting its neck or flippers. On the other hand, there are bits of floating foam or other debris like this, which over time accumulate all manner of algae, plant life, and eventually, marine animals. This bit of styrofoam was now home to all kinds of life, including barnacles, small fish and crabs. At this point, it seemed unlikely to pose a hazard to turtles. On the other hand, ripping it out of the water would immediately cause the destruction of a whole ecosystem, with an unknown number of animals that called this ocean slum a home. A couple of months back, we came across a sargassum fish, which is one strange ranger, floating in debris like this. So for us, every bit of floating garbage is an individual issue, and we may or may not pick it up. Today, for better or worse, we let harmless trash lie.

About two weeks ago, we came across a large plastic bag trailing a long monofilament line in the ocean. I had so much to write about that day (see Oct. 25 blog!), that I couldn't make room to discuss it. Near South Point on the Big Island, where a strong wind blows almost everyday, many shore fishermen use plastic garbage bags in a fishing technique called "kite fishing." They blow the bag up with air, tie it closed, and attach their fishing line to it. They then launch the improvised "kite" in a windy area and let the wind and water currents pull their fishing lines out to sea. In this way, they can get their fishing lines out to much deeper water where they have a chance of catching some offshore species like ahi (yellowfin or bigeye tunas), aku, ono (wahoo), mahi mahi and even marlin. For people who can't afford a boat, this may be their best chance of landing those excellent eating fish. On the other hand, predictably enough, plastic bags end up getting lost at sea. It's deplorable, but it happens.

On that day, we retrieved the plastic bag from the ocean. We looked around for what kinds of marine life might have called it home, and found only two tiny crabs. Sorry crabs, but in the interest of the greater good, we appropriated the trash. So you see, folks, in our world, some trash gets picked up and some remains where it was found.

Now I'll mention one last trashy item, but of the natural variety. Today we saw a large patch of weird yellowish-brown stuff floating in the water. It may have been an algal bloom of some kind. I have photos, but let's just say they lack sufficient impact to post here.

Next, we meandered about, trying to find "F" buoy. This is one hard buoy to find; it seems to drift 3 miles in either direction. We finally gave up and headed over to "C" buoy about 15 miles away. We had a short run with at least a hundred pantropical spotted dolphins there, but like the spinner dolphins we saw earlier, these didn't want to play in our wake. They were active and doing some nice leaps, but they were a bit too far away for any good shots, and soooo unpredictable!

At about 4:15, we saw a school of 'opelu (mackerel scad) or other small fish feeding at the surface. There was a good chance some larger predatory fish like wahoo, mahi mahi or tuna were gathered around those bait fish. Masa tried to jig for them, but had no luck. We continued out beyond VV buoy, and the 'opelu as well as some small tuna, such as aku (skipjack tuna), were jumping there, too, with a flock of birds swooping down around them. We thought the birds were brown noddies, and they gave me my best photos of the day.

By the end of the day, we had managed to catch a couple of good sized aku for our dinner out at UU buoy, and we headed home. It wasn't a great day for photography, so I'll just post a nice sunset, which is what we saw as we ended our day on the water off the Kona coast! Mahalo for checking out the blog!
