  • High Quality Hydrophone for Humpback Whale Acoustic Research
    is 6m The oil filled tube allows the array to be neutrally buoyant and either towed or hung vertically in the water with the minimum pickup of flow noise There is also a portable 96 kSa s 4 channel recorder in the centre of the image that will record sounds up to 48 kHz from the array onto an SD card Since the oil filled tube is 30m long we can deploy the 4 hydrophones at the depth of our choice up to about 20m below the surface This will allow us to record humpback sound at close range without disturbing the whales with the highest quality and with the possibility to measure their range and source levels Think of the 4 hydrophones as being able to record a kind of surround sound hyper stereo THX acoustic landscape After reading this a couple of times I think it means It s a kick a hydrophone that we can send down to 20 metres and record really cool whale sounds though I m not entirely certain Anyway we ll be using this high tech gadget on the trips that John and I are running together in Tonga soon with the objective

  • Humpback Whale Acoustics Research in Tonga
    in the movie John is quite proud of his performance so please try not to laugh when you watch the clip below Note Excerpt from The Cove used with permission from Director Louie Psihoyos John is a marine acoustics expert and he s also a Kiwi Correction John just informed me that he s not a Kiwi so I owe all you decent Kiwis an apology John is from Essex in the UK so please excuse the odd accent and crazed look in his eye We are kicking off a joint effort later this year to learn more about southern hemisphere humpback whales by studying the noises they make Specifically we ve organised a couple of itineraries 29 July to 2 August and 3 to 7 August on a liveaboard yacht to spend quality time with the humpback whales that visit the Kingdom of Tonga each year There are one or two places left so if you re interested in having a great time whale watching while also learning about humpback whale acoustics using cutting edge instruments i e toys please see my earlier post for additional trip details and drop me a line via my contact form if you

  • Adventures in 2010 | Lembeh Strait, Tonga, Ogasawara, Ambon
    mammal photography advice discussions about humpbacks in Tonga from me excludes accommodation meals etc off the boat and air travel While this isn t going to be as intensive a photography oriented trip as the others I have planned we will get into the water at every opportunity and we will be taking photos and recording video If you re interested in learning more about humpback whales and helping out with cutting edge acoustics study of whale song please contact me via my contact form To be honest this is a departure from the type of trip I usually do but it s something that I believe will be worthwhile over the long run in expanding our knowledge about these graceful marine mammals As with the humpback whale calf count that I started a couple of years ago John and I will make every effort to share via the internet any insights we gather and we look forward to feedback and contributions from all interested parties Sperm Whales Ogasawara early mid October Following on the incredible success of last year s inaugural trip to Ogasawara I m planning another visit to Ogasawara in October this year Among the highlights of last year s trip we photographed and video ed a group of female sperm whales eating a giant squid and possibly teaching the calf in the group how to hunt for squid which means this year we ll have to photograph a giant squid engaged in a life or death struggle with a sperm whale On a separate occasion I swam down and recovered a 351cm segment of a giant squid feeding arm We also found leftover deep water octopus parts swam with dolphins and encountered Bryde s whales Come to think of it we were quite busy While in Ogasawara I also realised that it s possible to ID sperm whales by markings on their lower ventral areas and I subsequently compiled a summary of nine individual whales that we encountered I m hoping to build on this ID catalog over time working with the local whale watching authorities to see if we can document repeat visits to the area by these enigmatic cetaceans The exact trip dates depend on the ferry schedule between Tokyo and Ogasawara Last year the ferry schedule was only announced in July and the trip was from 8 to 19 October though I had a good idea of the probable schedule a few weeks prior to the official announcement Also the exact cost depends upon the class of berth aboard the ferry the number of people on the trip and the number of days we re out on the water so participation in this trip requires a measure of flexibility A reasonable estimate is Yen 600 000 700 000 person for 8 9 days on the water Yes I realise that s not terribly specific but that s the nature of the situation and it s totally worth the effort and pain in the

  • Night Diving in the Lembeh Strait
    I saw a lot at night There were many cephalopods on the prowl like this little octopus that seemed truly surprised to see me and an adorable little bobtail squid sound asleep until my strobes went off The cutest crustaceans I came across had to be this little crab couple The one on the left encircling the one plunked down in the sand was always protective of the other crab and literally hugged the other crab every time they moved I suspect the cuddler was a male and the cuddlee a female Perhaps I m imagining things but it sure seemed like the crab I thought to be the male kept communicating She s mine She s mine every time I got anywhere close I didn t know how to reassure him by saying Not interested in crab language though In any case they were adorable Diving at night presents some unique opportunities to observe and photograph the residents of Lembeh as the critters active after dark tend to be different than the ones during the day There s also a lot of courtship and mating activity that takes place in the early part of the evening which is always fun to watch I m really looking forward to my next trip to Lembeh which will be for The Night Safari planned for 27 February to 6 March 2010 when we ll spend a large proportion of time diving at night The resort will be on a night schedule so we ll have all the logistical support we need to have an enjoyable time like having hot chocolate after dives While at Kasawari this trip I also arranged to have big lights for us to hang during The Night Safari above the water to get squid and perhaps other stuff

  • Travel to Tonga to Swim with Humpback Whales
    so Next year will be my 10th season in Tonga Over time I ve spent dozens of hours in the water with these whales and I ve learned a lot about how they behave With this experience I ve taken hundreds of people into the water for high quality personal encounters with humpback whales For just about everyone it s a life changing experience Even the most jaded and cynical of people who ve been there done that come out babbling like little kids after they ve experienced eye contact with a humpback It s an experience you can t really put into words You have to do it to understand Over the years I ve come to appreciate and enjoy everyone s reactions as much as I do my time in the water with the whales This year 2009 I organised a single seven day trip for six people from outside Japan all my other trips are for Japanese travellers To be honest I was hesitant about doing this as coordinating people from around the world and from different cultures poses a much greater logistical challenge than working with groups just from Japan In hindsight I m really glad I did it though as I made some really great new friends and I know that everyone on the trip thoroughly enjoyed this unique experience So for the 2010 humpback whale season in Tonga I m going to be a bit more ambitious and I m planning two trips six people per trip Trip 1 14 20 August 2010 Fully Booked Trip 2 21 August 31 August 2010 Fully Booked If you re interested in either of these trips please use my contact form to let me know If you re thinking about it but aren t really sure please

  • Special Night Diving Trip to the Lembeh Strait
    nudibranchs mating pufferfish mating you get the idea After each action packed dive I found myself wondering what it would be like to keep diving through the night I mean it s not like the hunting mating and other behaviour stopped at the end of our night dives Nope The critters of the night just kept on doing what they were doing and it just killed me that I wasn t able to go back in After the trip I discussed this with my friends David and Sanah of Scubacam and Aey and Mean from FiNS Magazine As a result of my obsession with nightlife we ve put together a trip to Lembeh from 27 February to 6 March next year to focus on diving at night an outing we ve dubbed The Night Safari 2010 The objective of the trip is to dive at night with a heavy emphasis on photography and video To do this we ve again enlisted the cooperation of Kasawari Lembeh Resort whose owners and staff have agreed to switch over to a night schedule for this crazy little project With its efficient layout amazing camera room and dedicated staff Kasawari is the perfect place to try something like this As far as I know nothing like this has been done before in Lembeh perhaps because not too many people would like to dive only at night or perhaps just because no one ever thought of it In any event this trip isn t for everyone If the thought of getting in pitch black water filled with mostly poisonous creepy things that tend to sneak up on you doesn t make you positively giddy with excitement then something s wrong with you then this trip probably isn t for you If the prospect of exploring
