Notes from the field: Another life list +1



While every day on the water is very special to me, some days stick out in my memory more than others. Today happened to be just one such day. We were cruising around, taking photographs of the whales for identification purposes, trying to fiddle with our acoustic equipment and suddenly Salva shouts, “what is that?” We turn around quick and there IT was….. A small black stumpy log that was puffing occasionally but otherwise, not doing much. Thankfully Salva started clicking, which is why I have a photo to share with you all. I cannot stress how important it is document unusual sightings in as many ways possible – photographs, behaviour and other notes – this kind of information is what allows us to determine what it is we are seeing. Good thing the team worked rapid fire because before we knew it, that creature had descended into the depths. We all agreed that it was a dolphin of some sort but it was something I hadn’t seen before. Once back at the house, we downloaded the photos and flipped through the pages of our field guide book and based on its behaviour we found it….a dwarf sperm whale! How ridiculously exciting for me!! A new species to add to my life list and such a elusive one at that!

Moments like this remind me of how mysterious the ocean can be and how many secrets we are yet to uncover…it reminds me how lucky we are to live in an age when we can still see these magnificent creatures despite humanity’s cruelty.... It reminds me how very lucky and blessed I am to do what I do and do what I love....thank you for letting me share my adventures with you!

Making Tony style lemonade


I've always loved Tony Wu's work. I guess its obvious given all the posts and reposts I've done about his photography. Yesterday's photograph is however quite different. When he sent this to me I looked at it and fell in love all over again! It was not crystal clear, there were stars in the water and the image looked more like a painting than a photograph. In my mind, the low vis conditions that we are experiencing off our coast added a further dimension to the image. As it turns out, the image is growing on Tony....he is getting used to it and learning to appreciate the challenge posed to him by mother nature. To me, thats an awesome attitude and the reason he excels at what he does!!

Here is Tony's take on this image and his first day on the water thus far....http://www.tonywublog.com/20130125/blue-whale-balaenoptera-musculus-diving.html#axzz2J2koHHrj

Notes from a future ocean hero


Anaaha convinced her parents to fly out to Sri Lanka from Bangalore to see the blue whales in our waters. Anaaha is just 8 years old. I had the privilege of speaking to her by phone very briefly and was struck by how much she already knew and how curious her mind was. My favourite question - how do you know that that red stuff is the whale's poo?

All credit goes to Anaaha's parents. One day she will appreciate the support they extended to her to achieve her dreams. Enjoy her thoughts on her day on the water off Mirissa.

All my bags are packed....

Happy new year! I m all set to go but it seems the weather Gods aren't cooperating again :( We have been experiencing inordinate amounts of rain - very unusual for this time of year - and of course Australia is dealing with a ridiculous scale breaking heat wave. Seems like the two places I split my time between are going through a rough spell.

Well, I am all packed and ready to flee south and spend some time on the water. I just hope the weather Gods allow me to do so....in true Asha style, I remain wildly positive.

Oceans - Heart of our Blue Planet


Does the ocean capture your imagination? Are you concerned about its status and all we are doing to it? Do you want to learn more?

Do you have an ipad? Download the FREE CEMEX conservation book about the oceans by clicking here https://itunes.apple.com/us/app/oceans/id478004100?mt=8. The book contains some remarkable photographs by the world's leading underwater photographers belonging to the International League of Conservation Photographers (iLCP) and is totally worth a browse. Consider it an early christmas present to you and your loved ones!

For those of you who do not have an ipad, you can see a selection of the amazing photographs by watching this short youtube video.

Noisy oceans



The National Oceanic and Atmospheric Administration (NOAA), is currently documenting human-made noises in the ocean which they then hope to transform into the world's first large sound maps. The ocean visualizations use bright colors to symbolize the sounds radiating out through the oceanic depths, frequently over distances of hundreds of miles. The map above is one such example. The hotter colours (reds) are areas of higher noise while the cooler colours (blues) represent areas of less noise.

The impact of noise on marine mammals is something that is generally hard to quantify - even though we know it is increasing and having devastating effects. For an animal that relies on acoustics for its survival, a noisy ocean is not a great place to live. Imagine it.

To learn more about this study, read this article http://www.nytimes.com/2012/12/11/science/project-seeks-to-map-and-reduce-ocean-noise-pollution.html?pagewanted=1&ref=science and make sure you listen to the sounds of the various sounds and the podcast on the left hand side of the page!

Results from Deepsea Challenge expedition!!!



Have you been wondering what interesting findings were made on this expedition? Here filmmaker and National Geographic Explorer-in-Residence James Cameron talks via Skype about early findings from his record-breaking dive to the Mariana Trench in March of this year. He and his science colleagues presented findings at the annual meeting of the American Geophysical Union in San Fransicso.

Blue whales pirouette before engulfing their prey: Watch this!



As if behemoth ballerinas, blue whales pirouette before lunging at their prey, a strategy that may help the giants ambush krill from below.

"This behavior probably improves the whales' chances to engulf the most krill possible," said study co-author Ari Friedlaender, a marine biologist at Duke University.

The new findings, detailed today (Nov. 27) in the journal Biology Letters, may shed light on how the enigmatic creatures hunt and devour their shrimplike prey......

Marine acoustics with Kelly Benoit-Bird


For the longest time the only thing I really knew about Kelly Benoit-Bird was that she was a recipient of the 2010 MacArthur Genius Award, which happens to be one of the most prestigious awards available. I then saw her keynote presentation at the Ocean Sciences Meeting last year and I secretly sent my approval to the MacArthur Foundation for their incredible choice. Kelly uses marine acoustics in novel ways to learn more about ecosystems in the open ocean. More recently I have had the opportunity to work very closely with one of Kelly's former PhD students, my good friend Amanda Kaltenberg. As a result I have learnt that not only is Kelly a genius but she also happens to be a great person, mentor and friend. 

Watch this short Pop!Tech talk to learn more about the work Kelly does!

Tongan humpback baby boom continues!

Calf number 19. A beautiful bouncing baby boy! Photo credit: Tony Wu
How many of you remember the Tongan humpback baby boom last year where we all oohed and ahhed at the amazing number of new calves in Tonga? My friend the incredible underwater photographer Tony Wu recorded 48 new calves in the 2011 season and that was a new record. This year, he went back. He recorded an incredible 52 new calves - that's four more than last year!!!

I encourage you all to read his blogpost here: http://www.tonywublog.com/20121104/record-number-of-humpback-whale-calves-tonga-2012.html
