  1. Hello Everyone ! This is not a Dive Trip as it is open all year round, but I though it was the best place to mention it as it is a heaven for underwater photographers. The Awakening Shark Dive runs from Barefoot Kuata Resort on a small island in the Yasawas, Fiji. It was created with sustainability and conservation as inseparable from any diving activity. The latest available scientific recommendations and experience from dive site around the world were collected to create a dive that is good for the sharks, for the reef, and for local communities. Extensive briefings allows you to learn more about sharks before you jump in the clear water offshore Yasawas islands. The dive has been setup to be easy for beginners and in fact, you can join us on our isolated island even if you never dived before, learn in a few day and jump in with the sharks. No deep-water, no current, helpful staff, so it feels as easy as any simple reef dive - but don't be fooled, it's a blast for experienced divers too ! The Dive is Photographer friendly and always try to give the best spots and angle for photographers. The dive can also be booked exclusive for one of few person, allowing more freedom and unique angles to see the sharks. There are also multiple dive sites around the resort, from shore dive in Marine Protected Area (including night dives) to deeper sea mounts, caves and tunnels, walls or simply nice and easy shallow coral reefs. You can also decide to spend the rest of your day at our pools, bar, or hiking the mountains of the islands ! In the water ? Massive well-educated bull shark swimming in front of you in a totally safe experience. We often hear "it's the best thing I've done in my life !" Find more with this presentation video : https://youtu.be/B2R_bQxaEr8 Here is the website : http://www.thebarefootcollection.com/diving/awakening-shark-dive.htm Or email : sharkdive@thebarefootcollection.com And a few photos from the dive : Contact sharkdive@thebarefootcollection.com for more information, booking, special groups or any other question !
  2. Acoustic tagging is not the same tool. It's very different and should be complementary when it can be used at all. The reason is that you need recievers to "record" the shark. The range is generally ~200m. You will have 0 information about where is the sharks when he is away from of the those recievers, which make it poorly informative in the case of pelagic/semi-pelagic sharks. It is a great tool for resident sharks however, because it will give you information about the daily routines of sharks. But of no use to learn about long migrations, deep sea uses, etc... edit : hope it don't go controversial but we did a quick recording in 2011 on a grey reef sharks - very easy sharks as they are very robusts. This is internal accoustic tagging. One could say very invasive but we have over 12 months cool data about their roaming around healthy : ) notice how thick the skin is on females. (and the divers under us at the beginning - if I remember well it was Bill Gates. We had James Cameron the next week ^^)
  3. I realize how glad I am that I'm mostly working with small robust sharks. Harder I've deal with so far are bull sharks that get tired pretty fast - you have to work really fast and make sure you release it is shallow waters in case he needs some help... some tonic immobility before release makes a big difference, they seem to "forget" what just happened and go back very peacefully. http://farm3.staticflickr.com/2441/5856937157_1a5dcc4fd2_z.jpg For the question about "do we need to catch GWS to tag them?", I guess it depend on several things including where you are (i.e. how clear is the water, can you approach GWS underwater without too much risk) which make it harder when you are elsewere than at Guadalupe... I think I remember there is great job being done in south Australia / New Zealand with some really cool large boat designed for GWS which allow fast and easy catch and release.
  4. (BTW, if I remember correctly, the Quensland alone is killing on purpose over 600 tiger sharks a year just so there is less chance that an accident happen. A illegal fishing vessel with 4 tons of sharks have been taken in new caledonia less than a month ago, and it's not the first time it happens. and there is more example like that all around. I understand it's important to watch that no organisation is doing bad things, but these hundreeds of deaths should be more in our focus)
  5. In a perfect world, everyone would understand that sharks need to be let alone, no one would overfish or even fish them, and we would be totally fine no knowing where they go. However, this is not the world we are living in. Sharks are killed. It raises concerns, and politician are listening to both sides : one that say "we are feeding people, making money, paying people to be fishermen, sharks are just fine we still catch a lof of them and when we don't we will stop anyway because it's not gonna be lucrative anymore and then they can recover" and then there is the people that don't want sharks to be killed. I'm one of them, and we have to "counter" the argument made before. We have to make politics understand that what "killing sharks" bring to society is not as important as "not killing sharks" is. In this world, we can't say "look they suffer", or "poor them they die". It just doesn't work. Politics don't care. We have to come up with solid argument and data and prove to politics why, without a doubt, they should trust us more than them. And doing so it happening through science. Now, it does not justify bad methods, and I am not saying that we have to kill a few to save many - I wouldn't do it because we don't know if we are going to save many in the end. I do not comment on the Ocearch as well, I don't know enough about them. What I can say however, it that catching sharks (hooks, nets) is the only way we have to do some sort of science on them. Tagging and genetics, which are used a lot today, both needs catching sharks. Because older scientist have been experienced shark catching, we learned a lot of tricks to make it easier for the sharks. I.e. circled barbless hooks, which species are the less resistants, how to handle a juvenile without hurting him, why you should not drag a heavy shark by the tail on a beach, etc.... All this techniques allows, if you follow the rules, to make it less stressfull for the sharks. At least for the "easy" species, you can catch and sample /tag individuals quickly enought to make sure there is no dammage, that he go back in the water just fine, and that he'll be here on his routine the next day. So, I guess the original message was : does Ocearch follow these rules, or do they unecesarly (i.e. for TV / to be cool or whatever) hurt sharks ? rather than "is sharks science a good thing?". Catching a shark can be stressfull for him, but if you do it right he'll be just fine. The only problem is, how "right" do you do it.
  6. No : I bought a new one recently, no vignetting as well. (however I do have vignetting when using this one : http://uwcamerastuff.com/precision_5_dome.htm ) maybe it's fine with the 5D2 because the combinaison of everything (housing included) makes it work. It might not be the case for other full frame combo.
  7. Christine - 5D2 + sigma 15 I have the ikelite with the : #5510.45 Dome Assembly and #5510.11 port body Absolutely no vignetting. You should double check this information. If you need a raw file taken with it, just ask. Best, Thomas
  8. (I have a 5D2 with Ikelite and the Sigma 15 : no vignetting with a large dome. awesome fisheye lense.)
  9. We are using energy, time and power to speak about this. They don't even deserve it. They'll grow when they'll be ready for it. We can't blame a baby that can't walk, and for the same reason, just look at this kind of people with a sweet smile and then ignore them : )
  10. Great ! remind me a serie I did back in the days. Always nice to see how much animals don't care about you when they are doing serious stuff : http://farm4.staticflickr.com/3081/2619242872_f810253248_o.jpg (sorry for the bad english)
  11. I actually think the black and white stripped surf board could make a small difference in decreasing the risks. It have been show in the past that sharks swim away really fast when they meet a simple fake killer-whale. In shallow dirty waters it might make no difference, but since it's cheap to paint your own board, why not. Just don't pretend it's for camouflage, a man won't camouflage in front of a shark. : )
  12. Hi everyone I recently saw this video. I was wondering if any of these could be applied to UW cameras : - add an extra protection in case of flooding - use it on your dome for under/over shots - use it on yourself/ your fins to get extra power swimming - use on the housing to limit the salt contact and other ideas ? : )
  13. There is no shark fishing in French Polynesia. It's forbiden and applied since 2006. There never was much fishing before that anyway. That's why it is one of the last shark's eden ! However, you might need to know the right spots to make sure you see a lot of them !
  14. Would do a great print ! I feel it could even get more negative space on the left to do a "panorama-like" giant print : )
  15. Whaling operator kills. I'm just saying, catch and release for science purpose can be a good thing, as well as chuming. There is many discussions and argument in this way that already exist, and we are finding, thanks to catch and release, genetics, tagging, many things that told communities how to best project sharks, or how do they live, etc... That said, once again, I'm FOR the banning. Here is a screenshot of a publication I recently did and wrote : But I could do and writte it because I caught and release sharks, hundreeds of them.
  16. ( just a quick friendly answer : I don't mean to say they shouldn't have forbid it, but it's really a pain in the ass to work on sharks when it's like that. Regulation (rules) such as no feeding (chum only) and only far from any beach / surfers sounds better to me. one example : It's still allowed to chum for Tuna spearfishing. How do you chum for tunas only without brining the sharks? will you get arrested when you chum in the water for other species ? what about the bycatch from fishermen (often happen in New Cal)? If you need samples for genetic, or to tag, or anything for the GOOD of the overall population of sharks, then it's really bad for you, and you might just avoid going there because you don't have the time and energy for months and months of papers and administration to get a permit. I agree "classic" feeding can be really bad, but non-commercial chumming for specific reasons by people who know what they do sounds OK to me. That said, I quote myself : "...but it's worth it". : )
  17. Great news. I'm not sure I fully agree to the part where feeding is forbidden, and it will make everything harder for people working with sharks (scientists / expeditions etc...) but it's worth it.
  18. hard to say, could be a C. falciformis...
  19. Hi everyone, Most of you probably knows facebook issue when it comes to photos. I've a seen a few pages where I could recognize photos from some of you without any link or mention of the ©. I though it could be good if we would share these pages and make some sort of list where we all can check and ask for removal or proper description. one example where you can quickly see emblematic images from some of us as you go down : https://www.facebook.com/pages/Royal-Diving-Club/153358394687263 Best, Thomas
  20. I recommend you NOT to bring the 65MPE underwater, it's a lot of trouble... ok, ok, but as well a lot of fun don't expect a high %age of succes.
  21. It's all great but a little hard to use for some features. You want to get used to the one you want to use topside before trying anything underwater. note that one of the big issue with ML is that the camera becomes very 'slow' (3-5 sec) to come back when it goes to sleep. You want to change your settings so it never does. But then, it uses more battery.
  22. Nice post Mark ! I agree with everything, I spent over 3 years of my life sailing around and I can confirm all this for the boat-related stuff (at that time I didn't have a housing). Contact with locals is probably the issue I miss most of the time. I tend to want to 'escape' from the human world, and even if I like getting in touch with small tribes and native in remote area, we always try to avoid areas with cities / hotel / crowded beach or crowded with other boats-bays. You're probably right for you double-gear thing. It will not stop me to have everything in double if I can (at least as a back-up if anything flood/break) and potentially to try using both from time to time, when the dive condition fit; i.e. under the boat on shallow sandy area. Your point with current is very important. I'll double it, and add that the water will be much clearer when the current come in. sharks will be there anyway, just not facing the same direction : ) http://farm6.staticflickr.com/5190/5859388486_a6ef4bbfb7_z.jpg
  23. Thanks Tim for this reminder. I'll keep it in mind. I believe it too, and have experienced it myself sometimes too. However, I do have a personnal vision of, let say, one week on the same spot, with two dives a day. My last 3 days will be aiming specifics like you describes. But if you want, for example, to write an article about the spot, you might want to use 2-3 days to just be 'productive' in number of good shots. No awesome shots, just technically good, describing the area or subjects. When you have that, you have the skelekon, the scene. And now is the time for your final pieces, your jewels, you personnal touch. this is generally what happens when you get in a new sea/country you don't really knows. The first dives you'll just come out of the water with 150 technically good shots of everything around. Then you learn what is common / boring, and to ID the special critters, or to ID the common critter that have the potential for special shots without too much effort. Then you want to do the effort, you just jump strait under the boat for some macro shots, sit on the sand on the first rocky area you meet, and spend your next 2 hours here Or go at the same nice seascape location freediving again and again waiting for a shark or a ray to pass by, having set your scene. Anyway, I need to learn this 'Aim' thing by myself better. It's never enough to just 'know' something, you need to experience it yourself again and again to fully realize it and apply. for now I'm just being productive because I don't dive much (what an irony !?). I'll get serious at doing less when I'll have more time ! Having potentially two set-up doesn't mean you'll do all your dive with. Maybe 1/4 of them will be already a lot ! But Thanks again, I know I will remember all this soon enough ; )
  24. Mark, I'll make sure I either go with someone when they are standard / hard dives. I'll keep diving alone for very easy non-risky dives in shallow waters, such as macro-under-the-boat. Always someone on the boat to check on me if I surface / don't come back. I've been diving alone a lot already, and have been formed to work underwater with specific training etc... also cave diving, nitrox and more : not to say "I'm good" or anything, but to say I am sensibilized enough to what the risk is, and to decide not to take it if I have any doubt. But, you're never safe... I'll be in different part of the world, potentially anywhere from cold to warm. Norway, BC, alaska, hawaii, french polynesia, australia, new caledonia, indonesia, africa... who knows ! but then it will be just 'sometimes', joining a sailboat roaming around the world. I'm waiting for all this and hope it will work good ! : ) Thanks for your photos NWDiver ! interesting... especially the strobes. I'll have to take that into account for my next housing ! I agree with you Liz. Also when I can, I'll throw lines deep down from the boat so I can always clip the housing(s) on it when I'm close from the boat. another idea : having small colored marker you can put around during the dive so you can find back critters : do a first dive wideangle, and come back for macro then ! Thanks for all your ideas, and still open for more ! : )
  25. Thanks for all the ideas. Unfortunately, I will often be diving alone (this is another debate), potentially from my boat in remote locations. So, in these cases, paying someone to carry the second camera isn't an option. The whole idea is to have a 'main' camera during the dive (i.e. shark dive, wide angle will be the main, macro would stay behind but will be here in case I meet a crazy critter). I guess the option with 2 clips on the side, under the left arm, could be the good one. (i.e. like when you take some extra tank with you : http://farm3.staticflickr.com/2612/4184052955_67e8ea12ab_o.jpg ) Did anyone tried a solution with a floating device 1-2 metters over the head? you can just grab it down and change in one clip. First you need to make sure your housings are balanced and will not be too heavy underwater. And to make sure you'll not cave or go under anything, unless you can drop the whole setup at the entrance and get it back later. ?
