Azores: fin whales and tags

After the successful sperm whale encounter, we next headed out south of Pico, this time in search baleen whales. There had been reports of ‘blows’ several miles off the coast of Pico, so who can pass up that opportunity?

Our mission was briefly interrupted by a wonderful encounter with some common dolphins, surfing in the waves and playing around the boat – a great start to any Sunday morning. Our photographer for the day (Martin) was duly put through his paces.

With our skipper (Jairo) then spotting a blow, it was time to move on. In building seas, large baleen whales are not the easiest to find, but when you have three fin whales blowing together it makes things a little easier. Spotting them was the easy bit – another new record for the 2019 expedition.  We followed them into the oncoming waves and wind that tested the resolve of all on board and made it tricky to get the ID photos.

The last couple of days have been on shore, working on images and yet more data. The team have already matched three of the sperm whales seen on Saturday to previous encounters in 2013 and 2008 – yet more small but important pieces of the puzzle.

Rui Prieto from the Azores Whale Lab also came over to the expedition base, to give a talk on his wider cetacean research and how some of the data being collected by the project is being used. And in other good news…he recovered his D-Tag (see previous blog).

Azores: whales and memories

Welcome to our second and final team for 2019. Our group truly embraces the international nature of Biosphere Expeditions, hailing as they are from Germany, Austria, Switzerland, United Kingdom and the USA.

This phase of the project started on a bright note. As you may know, Horta harbour is adorned with paintings, made by crews of the many ships that pass this way. On our first walk around the harbour, Lisa (one our citizen scientists from the UK) was able to locate a painting created by her late father, which she had not seen before.

With the team in place, briefings, orientations and training completed, we set out to sea on our first afternoon of surveying. This meant breaking new ‘ground’, as we headed for the channel between Pico and São Jorge. Our change in tactic from the first expedition didn’t prove to be as successful as we’d hoped.

After a couple of enforced days on shore, due to weather and sea conditions, we returned to the ocean. After a brief encounter with common dolphins, we were rewarded with whales – sperm whales to be precise. We followed a small group for several hours, getting fluke images of at least four different individuals, including a male.

At the end of the day, whilst following our last whale of the day, we were joined by a couple of whale watching boats from Horta. One was carrying two citizen scientists from our first group – always nice to share the whale experience.

Also on the agenda was the news of the power of our work here or more precisely, the results of photo ID at work. A long range matche of a blue and fin whale from the Azores to Galicia, Spain in 2017 has just been published. This shows how important it is to take these fin and fluke photographs to elucidate the movement of these enigmatic ocean creatures around the seas.

Azores: group 1 round-up

A sterling effort by group 1 over the past few days. We’ve covered in excess 250 km of surveys over the past three days, and again in some challenging seas. Safe to say everyone now has their ‘sea legs’.

We have also been involved in a mini collaboration with the local university, assisting them with a search for a D-Tag. This non-invasive tag (attached by a suction cup to sperm whales) can record the sounds heard, and made, by the tagged whale together with its depth and orientation (i.e. pitch, roll and heading), in a synchronised fashion throughout the dive cycle. The tag records data digitally for around 24 hours, depending on sampling rate. When if floats to the surface it gives out a radio ‘ping’, so it can be radio-tracked, once a rough position has been triangulated from land. Well, the theory is simple!

We were able to help in the search whilst conducting our own ‘normal’ surveys. Rui Prieto joined us from the local university (Dept of Oceanography & Fisheries) with his telemetry kit and all we had to do was spot a small yellow tag in the Atlantic – needle in a haystack – when dealing with 5 m waves. Sadly we weren’t successful on this front, but we did collect other cetacean data. We wish Rui luck in finding it!

Over the last few days, the team have worked their socks off, scouring much of the ocean south of Faial and Pico, up to 25-30 km offshore. The reward has been nine cetacean encounters, totalling over 125 individuals, not forgetting several loggerhead turtles. And let’s not forget our couple of expedition firsts – orcas and a singing humpback – more than data, they are truly moments to remember.

Just reward for such a great group who have personified teamwork – you have been a joy to work with, thank you. But as we say a sad farewell to group 1, we are excited to meet and welcome group 2. There is still much to discover, as we reach the halfway point of this year’s expedition.

Azores: Singing humpback

After the excitement of the orca encounter on our first day in the field, we were brought back down to earth the very next day… by the weather! High winds and worse sea states meant data processing was the only productive option.

So the team spent the morning with sorting and /or matching image files to enable identification and matching of several species, including sei and sperm whales; Risso’s dolphins and of course the orcas. Many of the orcas could not be matched with other individuals recently seen around the central island  group of the Azores, suggesting there are more out there to be found.

After an afternoon break, we were back out to sea the next day in slightly calmer seas. This began with common dolphin sightings, and four encounters later this was the only species we had seen all day, whilst navigating a loop south of Pico and Faial.

Eager for a change of fortunes, we set sail again on Wednesday. Luck was not entirely on our side. The dolphins appeared to be avoiding us, so we deployed the hydrophone to ‘listen in’ on dolphins and sperm whales but with no joy. But what we did hear – surprised all on board, including a scientist, Lisa – a singing humpback! Whilst the males are known to sing, often when in search of females, Lisa has never heard this behaviour in 30 years of working in the Azores. Another first for Biosphere Expeditions in the Azores. Fieldwork is about sights and sounds.

After several hours of searching, and with 110 km covered, we could not locate the humpback and finally had to give up on our singing cetacean. You don’t always get the result you want, but if your survey ends with ‘presence’ or ‘absence’, your data is zeros rather than ones, it is still a result.

Let’s see whether our humpback was just in rehearsal mode today, and we will get the full performance tomorrow…

Azores: Orcas!

The Azores expedition is officially up and running, and we can finally offer an Azorean welcome to our first citizen scientists of 2019. We have already been pushing the limits and the initial headline is a new species record for Biosphere Expeditions… but more about that later!

Our multi-national team all arrived safely, via a mix of routes and modes of transport. Some were hot off the plane and plunged straight into initial introductions, risks assessments and briefings. Not forgetting a whistle stop tour of Horta to get some bearings.

Saturday saw us dive into scientific training, with familiarisation of equipment, which was followed by data records training, and eventually rounded off with a boat orientation. Unfortunately the weather was against us, so we could not complete our first field trip as planned….that would have to wait. Patience is vital with fieldwork.

Sunday  saw us head out to sea. With winds blowing from the northeast, the conditions were best described as challenging. As we headed south of Pico, we eventually encountered some loggerhead turtles and a small group of common dolphins (great spots Stefi and Shantala), but encounters were hard to find.

The hydrophone was deployed in a quest to find sperm whales, but the conditions were just too extreme to follow them. With the sea state quickly reaching force 5 (the limit that we can effectively work in, and most people can stomach), we turned around and headed back towards the protection of Pico.

An inspired (if not lucky decision), for it was just off the coast (close to Lajes) that we had our first ‘whale’ encounter……with orcas! They had been seen in the area as few days before the group arrived, but normally move on. This is the first time they have ever been recorded by a Biosphere Expedition group. Great data and a wonderful encounter!

Our day was not done as we also found a group of Risso’s dolphins, with several young, as we began to cross the ‘choppy’ channel back to Horta. A quick baptism of cetacean research for some.

Field work will often push your limits, give you moments of luck, and reward your loyalty to your task. One of our citizen scientists, Neil, is a veteran of nine (!) Biosphere Expeditions and a previous participant on the Azores. Yesterday was very much payback for his commitment, in the shape of six beautiful orcas; and it was only our first day at sea.

Azores: Horta awaits

Expeditions always involve journeys of one sort or another. So after three days, three flights and four airports my annual migration to the Azores is complete. I even landed in Horta early, which is a first! Now the interesting part of the expedition can begin….

On the way to Horta

Today and tomorrow, Jim and Claudia (our hosts), and I will be preparing the expedition base for your imminent arrival.

It has been great to re-orientate myself with Horta, meet up with our hosts and catch up with Lisa (our scientist) to hear about all the recent sightings! We can share more detail on that once you’ve arrived… We now just hope that the weather and whales (and other target species!) are on our side and we can look forward to some great fieldwork (and data collection) over the next few days.

So safe travels to those of you still en route, and we look forward to meeting group 1 tomorrow.

Azores: First entry 2019

Hello Azores expeditioners

It’s time for the initial introductions. I am Craig Turner and I’ll be your expedition leader in the Azores this year.

Craig Turner

It is great to be going back to the Azores again, making my annual migration from the north of Scotland to enjoy the marvels of this mid-Atlantic location. And escape a pre-Brexit Britain!

I am currently organising and packing my kit, checking that I have all I need for the next month – so don’t forget to check the project dossier. It will be great to meet up with friends and colleagues from previous years, not least, our scientist Lisa Steiner.

Lisa Steiner

If you want to find cetaceans in the Azores, then she is the person to find them. I hope you have read the latest expedition report and Lisa’s publications on sperm whales, humpback whales, photo ID, marine predators and long-distance movement of sperm whales 1, 2 and 3 ,then you’ll know, not what to expect, but what we hope to record. Last year, you’ll note we had a variety of records – so you never can be too sure what ‘data’ we will collect. With Lisa already reporting sightings of humpbacks and sperm whales, not to mention the odd turtle, we could be lucky again.

As you can read in the 2018 report, this is what we’ll do

• continue the photo ID work on the various species

• continue matching fin whales to confirm if the fin whales visit in multiple years and send to other catalogues around the Atlantic

• start matching Sei whales to confirm if they are visiting repeatedly, as well as sending images to other catalogues around the Atlantic

• put more effort into the trash survey, as part of the POPA programme, which began in 2016. Marine litter is already a huge problem, with micro plastics finding their way into the fish we eat. Maybe even have a dedicated beach clean during the expedition

I arrive on Wednesday morning, a couple of days before the expedition starts, in order to set up. I’ll send around another message once I am on the ground in Horta and confirm my local contact details.

This reminds me to mention communications on the island. There’s cell/mobile reception on Faial in addition to internet via public hotpots and free WiFi in most cafes, but remember the golden rule of no cell phone communications while we’re at sea. Hopefully, you can resist the need for frequent international comms, and why not go off-grid for the expedition, and soak up the experience of Atlantic island isolation.

I hope you’ve all been eagerly reading your expedition materials and know to bring many layers of clothing. The weather can be a bit like four seasons in one day, so prepare for warm, cold, wet and dry – usually on the same day. Just like the weather in Scotland! Don’t forget your waterproof trousers – you’ll thank me when you are stationed on the bow of the boat as a lookout and the weather is choppy (so also bring your motion sickness pills/patches – if you know you need them!).

With the local team in place, whale sightings already logged by Lisa, all we are missing is you. It will be great to meet you all. Safe travels and here’s to another month working in the EU!

Expedition leader

Kenya: Data to send Rebekah over the moon

Apologies for the delay, but I was busy packing up and getting back to Europe.

Team 2 left Enonkishu last Friday morning. A month of expedition and data collection at Enonkishu conservancy is over. After this year’s final vehicle transects on Thursday morning and data input, Rebekah presented a summary of our work effort.

Group 2 completed 14 vehicle and 6 walking transects, 3 point count observations from Kileleoni hill and 20 four hour shifts of waterhole observation. During the vehicle transects, 619 observations were recorded in 43.5 hours on the activity (218 person hours) and a total number of 4,541 animals from 28 different species were counted. 23.5 hours were spent on the walking transects (141 person hours), where 59 observations were recorded and 293 animals from 21 species were counted. In 3 hours (18 person hours) of point count observations, a total number of 99 animals of 9 species in 20 observations was recorded. The team spent 78 hours observing the Memusi dam waterhole (179 person hours), counting 413 animals of 11 species over 246  observations.

I know, the above long list of numbers may be difficult to digest, especially for those who haven’t been involved in the activities on the ground. But the overall results speak for themselves: During four expedition weeks 1,682 observations were recorded, each a line completed on a datasheet and transferred into the computer. The teams spent 265 hours on activities making it a field effort of 940.5 hours by person – excluding preparation & travel time. A total number of 9.663 animals were counted.

In addion team 1 set up ten camera traps in different locations throughout Enonskishu and the SD cards were then changed every week. Expeditioners spent many hours sorting a total number of 8,829 photos/videos and picking out predators and nocturnal species such as lion, leopard, hippo, etc.

All in all our efforts look like this:

Also, the inventory species list we started on expedition day one has grown almost every single day including rare sightings such as aardvark, caracal, green mamba, leopard, honey badger and nile crocodile. 106 different bird species were spotted and identified – thank you Rebecca and Peter!

But enough of numbers & figures for now. Rebekah is over the moon with having a huge set of data to analyse and work with. And you will all be informed once the expedition report is published. Speaking for myself, I am still overwhelmed by the beauty and richness of the Mara and Enonkishu conservancy. Thank you to everyone involved in making this project a success. Thank you Albanus for making us feel welcome and comfortable at Mara Training Centre, Musa for sharing your knowledge and working with us, Joseph & Bernard for feeding us well. A special thanks goes to the Enonkishu rangers for keeping us safe and sharing their knowledge. And last but not least, thank you so much teams 1 & 2 for everything you have put into the project and coping with long days, night shifts, pouring rain, flat tyres and watching videos of moving grass for hours. Without you this project would not have happened. I hope you all take some good memories of Africa back home and I hope to see some of you again some day.

You may already have seen Chris Taylor’s blog and stunning photography, as well as Valery Collins’ blog. There’s also a flurry of posts on Rose Palmer’s website and Instagram.

Our “own” photos, courtesy of many of you (thank you), are below. Do not forget to share the rest of yours via the Pictureshare site please!

Best wishes,


Kenya: Shifts, students and rhinos

We finished the 72 h waterhole observation on Tuesday noon. Thank you, team 2, for completing this far from easy task by filling all morning, afternoon and night shifts, coping with rain, driving at night and slippery roads, as well as unrecognisable sounds during night time. Rebekah & I were pleased to have the team together again after three days of teams going in and out in pairs every four hours while others went for the morning & afternoon wildlife survey activities. During the review on Tuesday afternoon we shared our experiences. Some of the team enjoyed sitting quietly in the hide thoroughly, some found it was an enjoyable and a very special experience – especially the night shifts are something to remember.  Others were rewarded with rare leopard sightings, which is what everyone had hoped for, but couldn’t be expected. Others got “lost” on the way and were late for changing shifts or sat out a thunderstorm and heavy rain in the car while continuing the survey count every 15 minutes.

On the Environmental Educational Day on Wednesday, the team welcomed and hosted another group of 19 students from Emarti secondary school. After a tour through the boarding school’s facilities everyone went out in cars for a game drive within Enonkishu Conservancy. Soon a radio call reached the teams that two white rhinos had walked from neighbouring Ol Chorro Conservancy into Enonkishu territory, followed by their guarding rangers. For both the students and expeditioners seeing the rhinos was the highlight during the game drive. The afternoon at Mara Training centre included three “stations” run by team members: Chris flying & explaining a drone outside, Carrie & Rebecca explaining camera traps & showing videos/pictures at the classroom and placement Leonard answering questions from a local point of view in the cow shed. Former teacher Ellen did a great job with dividing the students into smaller groups and initiating the group rotations by imitating hyaena calls. We finished up with taking a drone picture of everyone lying in a circle on the grass to memorise this very special day.
