Feb 2012 - new field season beginning

During February, Ruth has been up in Walvis Bay running a MarWise course - this is a training and education course aimed at ocean users interacting with marine mammals - see her blog about it here.

Simon and Tess have been down in Cape Town, writing papers, writing grant applications for more funding, finding students and volunteers, buying the relevant equipment, building the new website and just generally sorting out a million little logistical challenges for the next field season.

We'll be heading up to Namibia by the end of Feb to start the new Nedbank Go Green funded project surveying the Namibian Islands Marine Protected Area in conjunction with the Ministry of Marine Resources and Fisheries.

In other news - YAMAHA have supported the Project by providing us with new 7-HP 4-stroke motors at cost price - this is very generous of them and they are currently being shipped to Namibia to be fitted for free by Skeleton Coast Yamaha.  Getting new engines for the boat will make a huge difference to the project - increased reliability and the ability to travel further will mean more data collected in more areas, 4-stroke motors are also quieter and more fuel efficient which will make a big difference to our pollution levels and carbon footprint on the water!   So a BIG thank you to both Yamaha and Skeleton Coast Marine!

One minor glitch in the plan is that cost price is still far from free. The NDP is looking for additional funding to cover some of the R150 000 for the motors.  If you are interested in supporting marine research and conservation (as a person or a company) - get in touch.  Your branding on our brand new Yamaha motors will look great!

Latest news - Dec 2011

In December, Tess and Simon attended the 19th Biennial Conference of the Society of Marine Mammalogy, held in Tampa, Florida. Over 2000 people attended from all over the world and this meeting is the biggest of its kind globally. [Conference Website]

Simon had a talk accepted and spoke about the research the NDP has been doing on bottlenose dolphins in Namibia entitled: Considering behaviour and individual identity in defining a protected area for an isolated population of common bottlenose dolphins (Tursiops truncatus) in Walvis Bay, Namibia.

The talk was very well received and it was great to get our research and Namibia's cetaceans on the map.

In other news:
Ruth and Simon have also managed to get a short note out on sightings of leatherback turtles and killer whales in Namibia based on collated sightings from our own work and sightings made by various tour companies. A special thanks must go to Francois Visser of Levo Tours, and Mike Lloyd and Orlanda Sandinha of Catamaran Charters for sharing their sightings with us.  Please get in touch if you'd like to get a copy of the paper.

Lastly - we're currently building our new 'proper' website which is partly why updates have been slow on here - this site will soon link to the new website and vice versa.

Meeting of minds

By Gabriel Al-Najjar - Oceans Intern August 2011

I’m now halfway through the internship living and working with people from all over the world and still feeling like there is so much to do and learn. That’s not to say I haven’t been fulfilling my goals for the month, but a month is a relatively short time to take in everything there is to see. Up to this point, the most memorable experience in the whole trip has happened in one minute; one minute of pure significance and amazement. I was out on the water where we had encountered a group of bottlenose dolphins with about 7 individuals. I had been documenting their behaviour, so I was able to really focus on everything that they were doing: every jump, every breath, every action taken above the water or next to the boat. We had been with them for about half an hour and this is when it all happened. One of the adult dolphins came up to our boat to the side I was on, and had turned on his side in such a way that he could look up at me. At first I wasn’t sure what he was doing, and that’s when Simon said “He is totally looking up at you right now”. In that instant, I knew that I was experiencing something that I had longed to be a part of since I begun aspiring to be a field biologist. The dolphin had continued to swim with us and fix his gaze for about a minute before breaking our locked eyes and dashing off to reunite with his dolphin friends where he belonged. To see these magnificent creatures in the wild as free beings and have an interaction like this one has, in a way, made the whole trip worthwhile. That is one minute of my life that I will never forget.

On tourism..

by Alyssa Avery - Oceans Research Intern August 2011

Tourism in the winter months at Walvis Bay is at a high making July and August the busiest months for the companies. Most boats are filled with people who either prepay for the trip, or have reservations for the trip. However, every so often one of the interns gets to join the boat on its tour of Walvis Bay to see the marine life. While this may just sound like a fun day off, it is actually work even though they give you “Namibian Coffee” which is actually sherry, but they don’t tell you that. Being on the tour boat is different from being on Nanuuq, or being in the office grading photos, looking at acoustic recordings or evaluating the forms of data collected. Our job while on the boat is to see how many animals either boards the boat (yes it does happen, especially with the seals who like to board the boats for fish) or how many animals interact around the boat. We also make note of how many fish are fed to the local seals, seagulls, and pelicans that are encountered throughout the three-hour boat ride and the seagulls really do sound like the ones from Finding Nemo. We do this to see how tourism is affecting the marine life, and if there should be something done to give the animals a ‘safe zone’ where boats could not go, or give the animals more distance. That way it would be the animals’ choice to interact with the numerous catamarans, ski boats and kayaks that encircle the area on a daily basis.

Interning in Namibia

by Jaime Werenka 

My first week as an intern for the Namibian Dolphin Project went super well. I found it pretty easy to adjust to the house and town and everyone is really sweet. The work is hard but enjoyable- yes even the office work isn’t too bad. In fact an office day is almost like a day off because it is so chill. We have early mornings and early nights here - falling asleep at 9pm is no problem after a few days work. And as all of us interns had been warned but hoped differently, it is cold here in the winter.

The first week came to an exciting close with the necropsy of a False Killer Whale. Simon received a phone call about a whale washed up on the public beach in Swakopmund just as our work day was starting. Awesome!

The False Killer Whale was already dead when we arrived but it was still warm. It looked like as if it was a life size plastic toy. We took several measurements at first and found that it was a 4.02m long juvenile male. Simon and Tess decided that head of the whale should be removed so the skull could be taken to the national museum in Windhoek. Well you can’t exactly leave a decapitated whale on a public beach. So the necropsy, which took approximately five hours to complete, began. It was pretty gruesome but so amazing. I readily put on some gloves, grabbed a knife, and dug in. Literally.

It was also very educational. Simon and Tess showed us the heart, lungs, kidneys, intestines, stomach, and pretty much everything else there is to see. A unknown growth was also found and kept for further observation along with other whale bits like the stomach and testes.

Tomorrow the stomach will be cut open because the weather has been no good lately for boat work. We will be checking the contents to learn about the diet of the whale, as well as examining the stomach for parasites like worms.

[ Note - subsequent to this post being written, we have opened the stomach and it was full of full of squid beaks and large, freshly dead (but unidentifiable) fish, so clearly the animal had been eating recently ]

So far it has been an amazing almost two weeks of raw science.

False killer whale stranding in Swakopmund

A dead false killer whale (Pseudorca crassidens) was found by Swakopmund residents washed ashore on the morning of the 6th of August in the Mole. The animal appeared to have died very recently. The sighting was reported to the Walvis Bay strandings network and the NDP were on the scene soon after it was reported. We took a  set of standard measurements from the animal and several samples for molecular analysis and collected the skull which will go to the National Museum in Windhoek. We also looked for the the possible cause(s) of death by looking for signs of illness including tumours and parasites. The stomach was removed and the contents will be analysed in the coming weeks to assess what the animals had been eating prior to its death.  

The false killer whale was male, was just over 4 meters in length and likely to have weighed around 600 kgs.  Its teeth were severely worn down which may be to be a sign of old age or that it was feeding on sharks and rays which have very rough skins. False killer whales normally live in deep offshore waters along the continental shelf edge. They are part of the oceanic dolphin family and mainly eat fish and squid.  Like ‘real’ killer whales, they occasionally prey on marine mammals as well. There is no information about the number of false killer whales in Namibian waters, but they may be threatened by fishing activity and offshore seismic exploration for oil and gas which leads to a high degree of sound pollution.  

Being on one of the main holiday beaches in Namibia, we had quite an audience throughout the necropsy, including lots of small children who were all very fascinated by the inside of a whale!

Community Outreach Programme

by Simon Elwen
This year the NDP and Oceans Research has been developing an Education Programme or “Community Outreach Programme”, aimed at both adults and school learners. Heidi Etter, has been developing this part of our work.

On the 11th of July we held an evening of public talks at Oceans Restaurant in Walvis Bay, along with John Paterson of the Albatross Task force. This evening was initiated and hosted by Marko Jansen van Vuuren of Catamaran Charters and we used the opportunity to sell some of our photos to raise some funding for the Education programme (for printing, laminating and a projector etc). The evening was a great success and we had really positive feedback and interest from the people who attended and managed to raise a few thousand rand for the project! We’ll be giving another evening of talks up in Swakopmund on the 9th of August at the Swakopmund Museum (19h00) so please do come along to that if you can!

Heidi has done a great job of making contact with the local schools and in developing materials, so we’ve already managed to have education days at two local high schools. Last week a baby Heaviside’s dolphin was found stranded along the beach south of Walvis (by Naude Dreyer again) and since the animal was small and easy to move around, we used the opportunity to perform the necropsy as a demonstration. We did this for the Grade 12 biology learners at the International School. I think they got a lot out of it and we’re looking forward to future education events. It was great having Dr Sonja Heinrich (a colleague from the University of St Andrews who works on the Chilean dolphin, 'sister' species to the Heaviside's) with all her experience involved as well - she's been visiting us and the dolphins for the last two weeks.

Some photos below of us with the students at the dissection with the International School.
