Update from our SCUBA diving volunteer opportunity & conservation holiday on the coral reefs of the Musandam peninsula, Oman

Greetings from Dubai – our preparation day has been very successful, beginning with a trip out to the Dubai Desert Conservation Reserve (DDCR) to collect our kit boxes that have been in storage there for the past year. The DDCR is our partner for our Arabia expedition (www.biosphere-expeditions.org/arabia) which runs each January, monitoring Arabian oryx, Gordon’s wildcat, and other flagship species, and they also kindly guard all the equipment we need to run the Musandam expedition as well. Once the kit had been checked and the car loaded, we went back to Dubai in search of an essential piece of O2 delivery equipment, without which we could not set sail tomorrow. After a hectic couple of hours, it was sourced, found, and collected! Thank you Nasser for your help!

Our next port of call was the iconic sail-shaped Burj Al Arab hotel where we met with David Robinson, their head aquarist. He took us behind the scenes, showing us the turtle rehabilitation work they are doing in Dubai, taking injured hawksbill and green turtles that get washed up on the beaches, and nursing them back to health for release back into the open ocean. David told us that there are only 60 breeding adult female hawksbill turtles left in the whole of the Southern Gulf of Arabia. This dangerously low figure is due to loss of habitat, unsustainable fishing practices and other anthropogenic influences.

On our tour we saw the aquarium’s leopard shark, now 7 years old, born parthenogenetically, i.e. without external fertilisation. David was very excited, as yesterday, she too exhibited the first signs of laying her own clutch of eggs. Leopard sharks are only the 3rd species to show parthenogenesis in captivity.  David is not only working in Dubai, but is conducting research on whale shark ecology. As part of his PhD, David formed Sharkwatch Arabia, a database to collect whale shark sightings throughout the region. He recently discovered a massive aggregation of over 150 whale sharks in Qatar. Protected by the presence of oil rigs, the waters are not fished, and tourism is prohibited – a strange but effective MPA. He asked us to keep a lookout for whale shark and other shark species during our time in Musandam, as they are likely to be present in the areas we are surveying. We did indeed have a whale shark encounter two years ago, in the same location, so keep your eyes peeled – and remember, it may be above you!

So, after this very informative and enjoyable meeting we bid our farewells and rushed back to the Holiday Inn to collect another consignment of equipment – all in a day’s work!

It may be a few days before I can send another diary entry as internet connection out on the Musandam peninsula is sporadic to say the least, but I look forward to meeting you tomorrow at 09:00 – let the expedition begin!

Hello and welcome to the first instalment of the Musandam diary.  I am Catherine Edsell your leader for this year’s expedition to the Musandam Peninsula. I have led this expedition for the past three years and feel privileged to be able to take you to such a stunning environment – we have a great expedition ahead of us. I trust all your preparations are going well, and I look forward to meeting you in Dubai at 09:00 on 25 October in the foyer of the Holiday Inn Express Jumeirah, our departure point to the northernmost tip of Oman.

It is our aim to replicate the surveys we performed in 2013 and 2011 as only by obtaining comparative data can we gain an insight into the true state of reef health. This year is an El Niño year. Sea surface temperatures are rising and as I write this, corals around the world are dying due to the intensity of this phenomenon. The temperature of the waters surrounding the Musandam Peninsula are always higher than the global average, making it a unique study site, as the corals here are already adapted to warmer temperatures. It will be interesting to document how much resilience they have and whether they are being affected. This is our quest.

To be able to collect accurate data, Dr. Jean-Luc Solandt our expedition scientist, and I will first need to train you in Reef Check methodology, so please have a look at all the training materials available on our website (see your dossier for details), as the more familiar you are with the indicator species of fish and invertebrates and types of substrate we will be studying, the better!

Update from our volunteer vacation / conservation holiday protecting whales, dolphins and turtles around the Azores

Decade of data from citizen science confirms cetacean hotspot

Information on cetacean sightings collected by Biosphere Expeditions’ citizen science volunteers in the Azores are confirming the importance of this region for a variety of species, amongst them humpback, sperm and blue whales – the largest species ever to exist on our planet.

Recent data have highlighted the importance of ‘site fidelity’ (the same individuals returning to the same location again and again) for species such as sperm whales. Indeed some individuals have been recorded multiple times since 2004, when Biosphere Expeditions first collaborated with Whale Watch Azores on this long-term project.

Cetacean specialist Lisa Steiner, the expedition’s scientist, says that “the collaboration with Biosphere Expeditions has led to repeat sightings of blue whales in different years, as well as matching humpback whales seen in the Azores to the Cape Verde Islands. We often encounter sperm whales that have been observed more in the early or late part of the year, and such information will help determine if there are ‘winter’ and ‘summer’ whales.”

But the decade-long data collection has not only revealed patterns of the lives of whales and dolphins around the Azores. Fluke identifications have been matched with individuals recorded further afield, such as in Norway. The project supports initiatives with both the University of the Azores and University of Florida, resulting in multiple novel scientific publications on the marine life of this unique archipelago.

“The volunteer data collection effort is vital”, says Dr. Craig Turner, the 2015 expedition leader, “as it helps unravel the detail in the lives of not just one ocean giant, but also resident species such a Risso’s dolphins and migratory species such as loggerhead turtles. The project is developing an insight not just into which species are here, but what these species are doing, where and when. This knowledge is vital for any conservation efforts, if they are to be effective.”

Dr. Matthias Hammer, Biosphere Expeditions executive director, adds: “The Azores is one of our longest-running projects and our collaboration with Lisa Steiner has given hundreds of people a unique insight into cetacean research and conservation over the years. It has also yielded a vast amount of data. We may not have headline-grabbing news every year, but it’s the steady chipping away at the block that makes the difference here, because the data collected by our citizen scientist volunteers are the bedrock on which effective conservation sits. The project as a whole is also a showcase of how volunteer-led commitments can go well beyond the support of a few years that are usually offered by grant-giving bodies. Lisa has shown an outstanding dedication to marine life that now spans several decades, so this long-term support is what is needed. We are proud to be helping Lisa in her efforts and look forward to many more years of working with her.”

From our citizen science project protecting leatherback turtles on the Caribbean coast of Costa Rica

I have just returned from the final reconnaissance visit to Costa Rica and I am pleased to say that everything went very well.

I have added some pictures and videos from the trip below. Hopefully they will give you a good impression of what it is like at Pacuare and of the work on the ground.

The expedition should be ready to join via www.biosphere-expeditions.org/costarica very soon and I hope you will join us. If you decide to do so, I look forward to seeing you in Costa Rica next year.

Regards

Update from our volunteer vacation / conservation holiday protecting whales, dolphins and turtles around the Azores archipelago (www.biosphere-expeditions.org/azores)

Sunday was finally a sunny day with calm seas and almost no wind. The first time this week!

The lookout on Pico Island had spotted some blows of sperm whales in the south. So accompanied by a school of common dolphins, we headed out. Pico’s summit was cloudless and gave a beautiful background to the calm sea.

The sperm whales surprised us and kept us busy the whole day counting their blow rates, taking ID photographs of their flukes and milling around while waiting for them to resurface after their deep dives – up to 45 minutes.

Two beautiful loggerhead turtles were seen, but they dived away before we could even get close to catch them for tagging.

Finally Blue Monday and with it the last day of the expedition arrived. I am not about to break into the New Order classic but these two words perfectly summed up the.

The first whale of the day was blue, and so was the second, and then the third. By midday it was already a remarkable day. However, three fin whales, at least four sperms whales and three more…yes, three more blue whales followed. Six blues in one day…it was one hell of a finale to the expedition.

And the best was saved until last, as our very last sighting was a fluking blue whale. Oh, and I almost forgot to mention the synchronised double fluking sperm whales earlier in the afternoon.

This was a fine reward for our team. Patience was tested over the last few days, with difficult sea conditions, challenging weather and sightings not always easy to come by!

But today the whale gods smiled on us. After a tense first hour, the sightings just didn’t stop, all day. This is the great thing about expeditions; they will always test you and then reward you in ways you don’t expect.

So we ended as we started, with blue whales. Yes this is great data, but also a humbling experience. Sharing the same piece of ocean with the largest creature that has ever graced our planet, can’t fail to stir the emotions.

So huge thanks to both teams, our scientist, Lisa, my two assistant leaders (Anthony & Chris) and our skippers (Nuno & Gyro). It has been a great expedition and we look forward to doing it all again next year.

So long

Update from our volunteer vacation / conservation holiday protecting whales, dolphins and turtles around the Azores archipelago (www.biosphere-expeditions.org/azores)

It may be the weekend but that is of no relevance to us. We have been back out to sea, and despite the seemingly ever present swell and winds, the team are happiest on the boat (mostly!).

Our main pursuit was tracking a couple of sperm whales, who periodically disappeared between the wave sets. Persistence does, however, pay off, and we were rewarded with a double fluke. Our other records of the day were common dolphins.

Working on the Azores project gives you a new sense of perspective on your reality, when seeing a couple of sperm whales and some common dolphins seems like a below average day…maybe only in a data collection sense.

Our slightly earlier return to the harbour, did give the team a chance to leave their lasting mark on Horta – completing the Biosphere Expeditions harbour painting (started by the first group). It seems tradition that every boat crew coming in or out of this harbour leaves a painting to mark their presence, and every surface is covered by a range of talents!

With our art completed, it is back to the science on Sunday.

We have been reluctant land lubbers for the past three days but that routine has now been broken. Today we returned to the sea. The weather is not ideal – winds too strong and waves too high. This all makes sighting cetaceans harder than normal. Such are the joys of fieldwork!

With our movements restricted to the calmer waters of the channel between the islands of Pico and Faial, the sum of the reward for the day’s efforts was a few encounters with small groups of common dolphins.

The conditions did also give us chance to enjoy some of the aerial acrobats, such as the Cory’s shearwaters, who are one of the targets for the bird surveys. Our feathered friends can get over-looked on ‘busier’ days, but they still form an important component of the surveys.

So a better than being stranded on land all day day. Birds + dolphins = data, which also means a happy team.

We’ll just have to try again tomorrow and hope our perseverance is rewarded.

Bad weather has stopped play. High winds, rain and large waves have temporarily halted our progress on the water.

Consequently, Tuesday presented the opportunity for most of the team to explore Horta and Faial – by foot, bike, moped and car! On Wednesday, the team were back at the scientific ‘coal face’ sorting data, organising photographs and matching images.

This slideshow requires JavaScript.

The great news is we have ‘matches’. At least four (possibly five) matches of sperm whales, identified from their fluke images taken by slot 1 on the 14th April this year. These individuals were previously recorded on multiple occasions as far back as 2004, when Biosphere Expeditions first worked in the Azores. It is great when all the hard work pays off and you can link the data points collected between the different expeditions.

So whilst we would have preferred to celebrate Earth Day out on the water, documenting new encounters with false killer whales, bottlenose dolphins and sperm whales, the team were able to join some data dots and complete another piece of the cetacean puzzle.

Our only whale of the day came in the form of a birthday cake for John – Happy Birthday.

Chris, Craig’s assistant for group 2, here this time:

Blue skies, calm sea…the second day seemed promising. Fears of churning stomachs were replaced with optimism as we took off in search of the cetaceans. The question is would they be more co-operative than on Sunday?

With no information from our lookouts, it looked like the flip of a coin would decide where to go. We headed to the south of Faial, where noone was looking. Some common dolphins made a good start, surfing our bow wave. Bob got the chance to do his job with the hydrophone, in the hope to hear some ‘metronomic clicking’, which would lead us to some sperm whales. Unfortunately these toothed whales were silent, but the dolphins were singing.

With wind from the southeast, we trailed west and suddenly the shout came: “Bloooowww”. Four fin whales travelling south of Faial were kind enough to show us some of their impressive white lower jaw, blow holes and dorsal fins – identification shots were bagged. Some bottlenose dolphins also gave us a fleeting encounter.

The faint clicking of the hydrophone suggested the sperm whales were out there, but our efforts to find them were interrupted when we suddenly ran into a school of 150 striped dolphins, jumping and racing along. Not a common sight here; and all were happy to be the first Biosphere Expeditions group this year to encounter these beautiful animals.

A sperm whale finally revealed its location by breaching with a huge splash in the far distance. Our pursuit was thwarted by rougher seas, but not before being waved goodbye by a sperm whale’s fluke. Random sightings of these mammals are rare, so also capturing the photo ID was a bonus.

While closing our circle around the island of Faial we encountered another single fin whale passing to the north. As the wind strengthened, it was time to head for the harbour. The data scores were better than yesterday, with more encounters and species. Our only zero was on the turtle front – the first time the expedition has failed to record one this year.

More to come…
