‘Seeing the world with different eyes’

‘I wanted to have an impact on protecting nature,’ says Angelika Krimmel from Germany, reflecting on what drew her to her first expedition with Biosphere Expeditions.

That first experience was in 2016, studying whales and dolphins in the Azores. It wasn’t long before Angelika found herself coming back again and again – to Slovakia in 2017 to monitor lynx, bear and wolf; to Kyrgyzstan in 2019 and 2024 for snow leopard research; and to Kenya in 2023 for African biodiversity conservation.

Whales, paw prints and camera traps

Each project offered something unforgettable. “After a week with the whales, you think nothing can top the first sight of one. But then a curious sperm whale swam alongside our boat, jumped three times and looked straight into our eyes. That look went directly to my heart.”

Germany : Over so soon

Update from our Germany wolf volunteer project

Yet another two successful weeks of wolf monitoring in Lower Saxony have come to an end. Group 2 left the NaturCampus base on Friday morning headed in different directions after a late night with lots of laughter and bread-on-a-stick around the fireplace.

Once more the teams were hit again and again by rain showers on our last survey day on Thursday but determination to find and collect wolf scat prevailed. Two of us established a new record of walking 22.2 km in ongoing rain!

Within 4 survey days group 2 covered 394 km of forest trails and collected 30 more (possible) wolf scat samples for further analysis two of which fresh enough for DNA analysis. Sightings on the survey walks included hare, red deer, roe deer, wild boar with 10 piglets, various butterflies and birds of prey… and a naked man walking the nudist trail in the Schneverdingen area. The survey team has been warned during Lotte’s briefing but it was still a surprise to run into someone wearing nothing but socks, boots and a hat while oneself was fully geared against rain and cold. 

Thanks to two groups a total number of 75 wolf scats and 13 genetic samples are now secured, labelled and packed to be handed over together with the database entries to the LJN authorities. They are an enormous addition to the Lower Saxony wolf monitoring efforts and will be included in their official yearly report, as well as territory statistics, maps, etc. to be published on their website. We have covered a total number of 26 cells (10 x 10 km) of the survey grid by walking 650 km in 12 survey days.

For Lotte & I it’s been a great pleasure meeting and working with all of you for a week respectively. We’d like to thank you again for your time, efforts, input and being great companions in every aspect. A special thanks goes to the drivers and NaturCampus staff that made us feel comfortable and at home. I hope you’ve enjoyed your time as much as Lotte an I did. We’re hoping to see some of you again some time and wish you all safe travels back home!

Azores : Round-up 2025

Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles

Whale watching can be undertaken in a matter of hours, but monitoring cetaceans to better understand their spatial and temporal use of different areas of our oceans – takes years. Biosphere Expeditions has just completed their latest expedition in the Azores, and is rapidly approaching two decades of monitoring, in an area of the Atlantic Ocean supporting over 25 different cetacean species.

Cetacean research questions cannot often be addressed (with any certainty) in a month or a single year. Data collection may take a decade or longer, to reveal meaningful patterns and this is the case with the cetaceans of the Azores. The true value may not always be in the ‘here and now’, but be realized as future questions or challenges arise. Such a data bank will only accrue value over time.

Some feedback is more immediate. Images of sperm whales and blue whales taken this year, have already be matched to other locations in the Azores, and northern Europe, across more than two decades. Some blue whales have not only been matched but never been recoded so early in previous years. yut many more whales have still yet to be matched, revealing range of their movements and importance of different parts of the oceans. Some individuals have only been recorded for the first time, again contributing to our understanding of population dynamics.

This year’s project still has a lot of data to process, from over 125 cetacean encounters over 15 days at sea, sighting over 1500 individuals. But some species are absent from this year’s research findings (e.g Sei whales) and dolphins have been found in lower numbers. On the upside, a few rarer records were noted such as orca, minke and Sowerby’s beaked whale.

With the expedition fieldwork continuing to commence in March, “it has also been great to extend the data collection beyond the normal tourism season”, says expedition scientist Lisa Steiner, “and collect data on a range of species, across a broader time span. The value of this work is huge as we wouldn’t have documented the range of species, including several sei, humpback, fin and blue whales, since there are fewer tour boats out at this time of year”.

Understanding spatial and temporal patterns of so many cetaceans is key to their long-term protection and conservation. And undertaking field research when others are not often at sea reveals new information such as species being absent or present in lower or higher numbers compared to other years.

“The ability to collect such data is greatly enhanced by the annual contribution of the Biosphere Expeditions citizen scientists”, says expedition leader Craig Turner, “and underlines the value of long-term data sets in illustrating the importance of the Azores for many cetacean species”.

This data-collection approach is being applied to other species of whale, along with dolphin species, such as bottlenose and Risso’s. The scale of the data collection both in terms of time and space serves to demonstrate the importance of the Azores for several cetacean species. And highlights the importance of appropriate conservation management, to ensure these species continue to thrive not just in Azorean waters, but elsewhere in the wider Atlantic Ocean.

Citizen scientist feedback:

The expeditions was very well organised. Craig & Lisa work very well together and you could tell they enjoy what they do. They cope very well when plans change, flights are delayed, weather changes etc . Amazing
Nicola B, Switzerland.

Our first day on the boat (also my birthday) I will never forget. I wished for a blue whale and I think we had six sightings that day (plus seven orcas!). Seeing the blow, seeing it just at the water surface and the beautiful turquoise colour before it dives. It was an experience way beyond what I expected. Accommodation was excellent. We were so lucky to have a view over the seas and Pico beyond. Great positive atmosphere of all the group members
Anne Clarke, UK.

The group dynamic was excellent and the leader really helped to create this. The expectations were handled well and we knew flexibility (weather etc) needed. So no frustrations or disappointments. Meals etc were excellent, science presentations very informative.
Peter S., Canada.

We found everything to be very well organised. A big compliment to our expedition leader Craig – what a wonderful guy – he kept everything going and the spirits up ; and to Lisa, our great scientist from whom we learned a lot. Loved the lectures from the Portuguese scientists who came to explain about their work on cetaceans. Loved to listen to Lisa who shared her unbelievable knowledge with us.
Gitta V., Netherlands.

This was a wonderful experience for me. Lisa & Craig are top notch organisers and kept things flowing. Briefing every day after outings and evenings were perfect. Selections of vegetarian options was excellent for me

Azores : People, place, project

Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles

That’s all folks. It is time for final diary entry. The end of the expedition is suddenly upon us, and five weeks seems to have flown by, with the international team now gone. Before I wrap the expedition, let me first recap the last few days:

Our final day at sea presented yet more great sightings. Most notably was another fin whale and not one, but two more humpbacks – one far easier to photograph than the other, but still a favourite amongst many. Add to this, more sperm whales, common and bottlenose dolphins and it was another great data haul. Sea conditions and our continued search for more sightings put us close to Capelinhos – the most recent volcano to erupt in the Azores – at the west end of Faial. This presented an opportunity for another first in 2025 – a circumnavigation of Faial – as the seas were easier to navigate to the north. Our 2025 data collection ended with our final loggerhead turtle.

This ocean-based tour of the island gave the group a better feel of where to visit on their day off – with many heading back to Capelinhos. But on our last day we were thwarted at the final hurdle, in our effort to go to sea, by bad weather, but this presented another opportunity to sort more data. Not how we would wish to end, but you can’t argue with the Atlantic Ocean – just accept that plans may often change. So that concluded our data collection and sorting, on another really successful expedition in the Azores.

This year we’ve again documented an impressive array of records that without Biosphere Expeditions, would not have been collected. Here are just some of our highlights. We have

deployed three teams into the field, comprising 8 different nations, spanning multiple decades
completed in excess of 84 hours of surveys, covering over 1400 km of the ocean
collected data on at least eleven different cetacean species (six whale and five
dolphin species), one turtle species and numerous birds
encountered more than 125 cetaceans,
confirmed some positive whale IDs, and several re-sights, but also have
numerous new flukes – i.e. individuals never recorded before

Data in isolation can be a bit ‘dry’, and lack context, as field research rarely gives us instant results (though fluke matches are coming through) or fast answers to our bigger questions. But we’ve collected another great baseline of data and the full results will become clearer in the expedition report. The power of this simple field data builds over time, as has been illustrated by our excellent invited speakers (thank you, to all).

Whilst we comb the see and learn about the cetaceans and contribute to the ongoing data collection on this project (19 years and counting), it is not always all about the project. What also makes the project so special is the people. So let me initially offer some thanks. First off, to our three groups, who stepped up to the daily challenge of data collection to achieve our goals of better understanding the spatial and temporal distributions of the cetaceans and turtles of the Azores. You’ve not only all contributed to advancing this knowledge and making this expedition a success – you have also been great fun to work with and not given the expedition leader too much stress!

We also thank the wider Biosphere Expeditions team, as this project can’t happen without the unseen preparation, often months before we even set foot on a boat. I also extend thanks to all in Horta who have supported us, particularly Norberto Divers, the lookouts and our various caterers – whose food has more than sustained us! We also extend our thanks to our hosts (Silvia & Mario) and the project base, of course to Lenita (our housekeeper) who ensured we were more than comfortable. I (like many) can also not forget our skippers (‘Pico’ Pedro & Pedro 2), who not only took us to sea, but ensured the team knew the sea state, wind direction, cetacean locations and always got us back to port safely – thank you gentlemen. Finally, our collective thanks go to Lisa. A constant force for knowledge and our leader in all things scientific. It is always a privilege to share in your world of cetacean fieldwork.

We have also had the great privilege of briefly experiencing life in Azores. As I mentioned in my very first diary entry (if you remember!), who doesn’t want to live on a volcano, in the middle of an ocean, searching for a diverse array of charismatic cetaceans. The allure of this fascinating archipelago is strong, and I don’t doubt that some of us will return, in the not too distant future – there are many reasons to come back.

For me personally it has been great to have the opportunity to return to the Azores, work on the project, in this wonderful place and meet old and make new friends. It has been a blast, but all good things come to end and now I too must make my way home. Time to head to my place in Scotland, catch up with my own family and see what projects we take on next.

Thank you.

Azores : New direction

Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles

The early part of the week brought a change in the winds, and a change of direction for our surveys. We initially headed north to follow up a report of a humpback whale in the area. This was our first time north of Faial this year, and heading into a north-westerly wind and building waves made the search harder than we wanted, but the humpback was finally located – a favourite species for many.

Staying with it brought more challenges, and having briefly lost it, the team spotted what we initially thought were the characteristic white pectoral fins in the waves, but this turned out to be a random sighting of Risso’s dolphins – doing their best to distract us. They achieved this briefly before the humpback was re-found and ID photos secured.

Subsequent surveys and sightings brought more dolphins in the form of common and bottlenose, the latter being less frequently sighted, but have now been located by all three expedition groups. So more dorsal fin ID images to process and catalogue.

We also spent a day south of Pico (very familiar territory) tracking sperm whales. It is still surprisingly easy to lose these magnificent beasts, as they can dive for 45 minutes. This gave us an excuse to deploy our hydrophone – a sophisticated underwater microphone – so we can listen in on the underwater world, and hopefully locate sperm whales and other species. It wasn’t as effective as we hoped, but our lookouts were able to locate more whales – with ‘eyes all around’.

Using the hydrophone kit was timely, as we welcomed Sarah Kather for dinner. She studied sperm whale vocalisations for her Master’s Thesis (at the University of the Azores) and gave a fascinating insight into the importance of sound-based communication (and noise pollution) for various cetacean species.

Amongst all this, Lisa also managed to match some of the sperm whale flukes documented from our earlier sightings, showing three individual females had been repeatedly recorded up to ten times over a sixteen year period. This further highlights the importance of the Azores to this species.

Fingers crossed for our final days on the 2025 expedition.

Azores : Azure expeditions

Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles

We have commenced the third and final part of the 2025 Azores expedition. It is great to have another diverse and enthusiastic group. With the welcomes, greetings, briefings and training sessions out of the way, we were all keen to get out to sea. Again, the weather made us wait a day, but used the day with more training and science presentations.

Our first day at sea was a triumph. Starting almost where we had left off – with a blue whale. That means blue whales have been seen on all but one day at sea this year – which is incredible. Next were a large group of sperm whales, who again were not the most cooperative, with very few fluking – so limited ID data, but a great job by the team for keeping up with all the sperm whale sightings. Add in some common dolphins, a loggerhead turtle, and this was a great start.

But our day was not done, it ended almost as it began, with another blue whale sighting, but this turned out to be a pair of blue whales – a first for this year. I am beginning to think we should rebrand to the Azure Expedition!

Our second sea day was less frenetic, but had a common theme – blue whales. We also recorded a large male sperm whale and common dolphins as we travelled along the south of Pico, using the volcano as a shield from the prevailing winds and thus take advantage of the calm-ish waters.

It has been a good start to the last leg, and here’s hoping our luck continues.

Azores : Whatever the weather

Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles

In the words of Crowded House, it feels like we’ve been ‘walking round the room singing stormy weather’, as the seas have put on quite a show. This has also curtailed our boat time but not put a full stop to data collection or image processing – there are always things to do on the expedition – whatever the weather!

Indeed the worst of the sea conditions provided an opportunity for a day off and time spent exploring Faial, and enjoying the visual spectacle of the mid-Atlantic. It also gave an opportunity to process more data, and the chance for another talk; this time from Cláudia Oliveira from the Azores Whale Lab on the role of photo-identification and bioacoustics for sperm whale studies. Again, illustrating the power of data collection such as ours.

Over the past few days, we have travelled almost 400 km over four days at sea. The group has been able to add vital cetacean data to this year’s haul, add a new bird species, and the numbers of encounters and individuals have also increased. A great effort by another great group.

So, as we bid group 2 farewell, we now welcome group 3; and we hope you bring the luck with the whales and the ‘weather with you’.

Safe travels all.

Azores : Restricted area

Update from our marine conservation volunteering holiday in the Azores archipelago, working on whales, dolphins and turtles

The Azores sits in the middle of North Atlantic ocean, but the weather and sea state can still restrict us to a relatively small area for surveys. This has been the case for the past few days.

Following a shore day on Wednesday and a chance to explore the island of Faial, we headed out to sea, more in hope than expectation. We were initially rewarded with an extended common dolphin sighting, close to the south of Faial. This was followed by a second encounter, in the waters protected from the worst of the winds.

Our luck then improved further, with a ‘random’ blow sighted, which of course turned out to be yet another blue whale. And during the course of obtaining the required ID pictures (great job Pixy), a second blow was spotted, but heading into the worsening seas, so we gave no chase. Whilst waiting to photograph both sides of ‘our’ blue whale, we spotted a ‘strange’ looking, almost leucistic gull. With images circulated to bird groups, it transpired that it was an Icelandic gull – a rarer visitor to these waters, normally seen in very low numbers over winter.

The day ended with an encounter with Risso’s dolphins not to far from home. The calmer waters meant a relaxed observation of four mums with calves. From the photos taken we could work out that one of the mums has been documented since 2006, so is likely to be over 20 years old. Well worth getting out on the boat.

Additionally, one of the blue whales recorded at the start of week was first recoded in 2001, and this is the sixth year it has been documented, but never previously so early in the year. We await news on some of our other sightings.
