Costa Rica: First diary entry

Update from our conservation holiday protecting leatherback and other sea turtles on the Caribbean coast of Costa Rica www.biosphere-expeditions.org/costarica 

Welcome to the Costa Rica 2018 expedition diary. My name is Ida Vincent and I will be your expedition leader. This will be my third year on this expedition and I look forward to being back at the Pacuare field station and working together with Latin America Sea Turtles (LAST).

Ida Vincent

The field station is located just behind the beach where the turtles nest and during our time in Pacuare we will work closely with the onsite biologist from LAST, Fabian Carrasco, who will be training us in sea turtle monitoring.

Fabian Carrasco

We both look forward to meeting you on 7 May. Fabian and I will already be in Pacuare preparing the field station for you arrival. However, Nicki Wheeler from LAST will be meeting you at 09.00 in the lobby of Hotel Santo Tomas. Make sure to be on time as our first night of patrols starts that very evening and there is a lot to learn prior.

I hope you have read about the excellent results that came out of our last report, and that in reading the report, you have familiarised yourself with the work in hand and how it is conducted. It’s going to be quite a bit of work, but that’s exactly why we need you. Have another look through your dossier and check your packing list; remember that your head lamp need to have a red light mode.

I will be a few days ahead of you, preparing everything for your arrival together with Fabian and Nicki. I’ll send my next diary update from Pacuare with turtle and weather updates.

Save travels and see you soon

Azores: Final entry for 2018

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

That’s all folks. Once again our expedition in the Azores has come to an end. Our citizen scientist have departed, the kit is packed and now myself and An must make our travels north, back to Scotland and Belgium. We’ve collectively had a great six weeks in the Azores. I have said this before, but expeditions offer many things, including difference, difficulty, diversity, discovery and of course data.

The last group have successfully added to that data in their last days, adding more records of loggerhead turtles, common dolphins, fin whales and seemingly the obligatory blue whale. I can’t remember a year on this expedition when we saw so many blues!

Before we talk about the discovery and data, let me initially offer some thanks. First off, to our citizen scientists, who stepped up to the daily challenge of data collection to achieve our collective goal of better understanding the ecology of the cetaceans and turtles of the Azores. You’ve all contributed to advancing this knowledge, and making this expedition a success. Thank you!

However, we must offer more thanks. Firstly to the back office staff at Biosphere Expeditions. There is always a lot of unseen work and preparation for any expedition. Secondly, thanks to Jim (and family) at Banana Manor, who have been our hosts for the past few weeks, giving us all a second home. I also extend our gratitude to Eugenio, Carey and Pete, who (amongst others) have catered for our variety of dietary needs. I must also not forget our skipper Jairo, who not only took us to sea, but ensured we knew the sea state, wind direction, cetacean locations and always got us back to port safely – thanks Jairo. And finally, our enormous collective thanks go to Lisa, our leader in all things scientific. It is indeed a privilege to share in your world and work with such a dedicated field biologist and cetacean scientist.

This year we’ve collected data earlier than any other previous expedition, giving us a unique and extended insight into cetacean movements. The lack of cetaceans on some days, or the challenging sea states may have frustrated us on occasion, but overall we’ve been able to amass a huge amount of data, that without Biosphere Expeditions, wouldn’t have been collected.

Here are just some of our highlights:

  • We’ve deployed four teams into the field, comprising 11 different nations, including people from 18 to 80+ years old;
  • We completed 22 days at sea, totalling in excess of 120 hours of surveys, covering 100s of miles of the ocean, and only ‘fed the fish’ on a few occasions;
  • We’ve collected data on at least 9 different cetacean species (5 whale and 4 dolphin species) and 1 turtle species;
  • Our total encounters with cetaceans exceed 120, and yes, simple statistics will tell you that almost one for every hour at sea;
  • We’ve also sighted and recorded over 1020 different individuals, and a staggering 57 loggerhead turtles;
  • We’ve also recorded 18 blue whales. Yes, we’ve ‘run into’ the biggest creature that has ever graced our planet, almost everyday we went to sea;
  • We also already have matches for three species of whale (sperm, blue and humpback) to other locations; and we continue to work on the matching and ID work undertaken by each group.

In isolation, these may just seem like bits of data, as field research rarely gives us instant results or fast answers to our bigger questions. But we’ve collected a huge baseline of data at a ‘new’ time of year for the expedition. The full results will soon become clearer in the expedition report.

So what of the success I mentioned? Well, I think the summary statistics highlight the success, but success isn’t always easy to measure, particularly when it comes to expeditions. It is influenced by the people you meet, the new experiences you have, the challenges you overcome, the wildlife you see…to mention a few. Ultimately, it is perhaps most dependent on your expectations.

We all come on expeditions for different reasons and with different expectations. No matter whether you are a citizen scientist, a professional scientist or an expedition leader, we all go on expeditions with a varying mix of nerves, hope and expectation. For many it may be for a new experience, to explore, to be enthused, educated, entertained and even enlightened! Some are lucky enough to achieve their dreams…

As leaders, we are the lucky ones to get to experience most of this, but we are also exhausted. So as we prepare to depart, we offer a final thank you for all your efforts and look forward to returning next year. And as always, we let the expedition speak through its picture and the group in their own words.

Azores: Seafarers and citizen scientists

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

The expedition continues to run its steady course. These past few days out at sea have been a real treat. The blue whales have crossed our paths every single day, becoming our favourites, even if these giants tend to be slightly elusive and play hide-and-seek in a vast ocean.

Nonetheless the team managed to get relevant data and valuable photos of multiple individuals that have been sent out to the experts and are now awaiting ‘matching’ – to see where else in the world ‘our’ whales have been recorded. One blue whale we followed even turned out to be two individuals, when going through Lisa’s images. These clearly revealed distinct patterns on the back of each.

This Sunday the lookouts detected multiple blows in different directions (South of Faial) and soon we realised we were not just following one fin whale but rather three, plus another blue whale! As a cetacean citizen scientist, you can of course never have ‘too many whales’ around, even if recording data can become a bit tricky. So with that spirit in mind we managed to add a humpback whale onto the data list before heading back to port – well spoted Anne!

And it is not just the cetaceans that keep us company…. Along our boat plenty Portuguese man-o-war, a jellyfish species, sail by, of which several will be eaten by the drifting loggerhead turtles we regularly observe resting at the surface. Cory’s shearwaters can also be seen in great numbers, walking on water as they take off and gliding as true masters of the sky just above the waves hardly flapping their wings. The smaller common terns are faster and gone in a blink of an eye. A rarer sighting was the Northern gannet, a species that occasionally visits these waters.

As days go by, the waves grow taller and the winds get stronger, resulting in noticeable progress in the seafarer’s skills of our citizen scientists: solid sea legs, unfazed stomachs, enhanced whale-spotting skills, navigational insights, weather monitoring, species identification and so on. For many the being out at sea is as much part of the adventure as the cetaceans.

Winfried took on the challenge of data recording on the front deck under the spray of a series of waves, while Julia was braving flying buckets of seawater to measure temperature on the stern. The POPA (Portuguese Fisheries Department) data dream team, Annabel and Chris, now excel in keeping their heads cool while multitasking to record everything simultaneously from trash, turtles, seabirds, cetaceans and more.

When the working day is over, it is time for a break. Anne, a Biosphere returnee for the last 7 years, introduced the ‘after whale-watching drink’ at Peter’s (the infamous harbour pub), supposedly for ‘a German coffee’. By now the whole group has embraced the concept resulting in cosy and tasty debriefing sessions.

As the sea conditions in the following days go into the red, we will be focusing on data analysis onshore and exploring what the island of Faial has to offer. Stay tuned for more!

Azores: Epic – says Team 4

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

Cetaceans are the stuff of myths, legends and dreams. But how do you make your dreams come true? Well, citizen science may have the answer.

Dreams of cetaceans would have to wait, as we had our final change of personnel, welcoming Team 4 to the Azores; our final team for the 2018 expedition. We also extend the Biosphere Expeditions welcome to An Bollen, our ‘expedition leader in training’, who is assisting me for the next ten days.

With the welcomes, greetings, briefings and training sessions dealt with, we were all keen to get out to sea. Our potential survey area was restricted by the sea conditions, and these also challenged some of our team – but great job by Amy for being the last volunteer lookout standing on the front deck.

The effort was worth it – an encounter with 75 common dolphins put a smile on all faces and data in our records.

Our first full day at sea was initially met with nerves and excitement. And again emotions were soon settled with another common dolphin encounter. Word of sperm whales then came in, and the ‘hunt’ was on. We quickly located several socialising groups, but none were diving, so frustratingly, no fluke identifications photos.

Time for a change of tack; so we went in pursuit of a baleen whale, that turned out to be blue. One blue turned into two blues, which did what the sperm whales wouldn’t – fluke! And it fluked multiple times, much to the delight of all.

Feeling lucky, we decided to try the sperm whales again, after encounters with yet more common dolphins and loggerhead turtles. After following several groups for an age, only two fluked briefly.  So again we went the way of the baleen whales, but this time pursued a humpback, and again it fluked – multiple times! So more ID photos recorded.

Quite a day for many in the group – with several seeing their first whales! However, on the first day we all met, Christine had stated she’d had a dream since she was child, to see a whale fluking in the wild. What she didn’t know was that citizen science would make that dream come true, and in some style, with three species fluking in one day. I told you (in my last blog) three was a lucky number!

Great day, great data and great reactions from the whole team. Their whoops and cheers are still ringing in my ears, but Christine summed it up neatly – ‘epic!’.

 

Azores: Team 3 ends on multiple highs of three

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

Expedition fieldwork challenges us in many ways. But often the greatest challenge comes from the fieldwork we can’t undertake.

Bad weather is one challenge. Patience is another. And this is often, eventually, rewarded. Our last day started like so many before, with common dolphins; but we rapidly progressed to multiple blue whales and sperm whale encounters, with more dolphins and turtles to add to the mix as the day progressed. To say it was a busy day is an understatement. It was also a long and physical day – trying to stay upright on the boat for 8 hours is no mean feat! Well done Team 3 – for your patience, commitment, work ethic and for handling the weather.

So Team 3 located three different blue whales, had three encounters with common dolphins, and found a group of sperm whales, where one individual breached three times!

This was a first for many, including the expedition leader. Their apparent lack of grace (compared to humpback whales) means they are referred to as flying cucumbers – albeit a 20 ton cucumber – and yes, it has to be seen to be believed! Yet another reason to come to the Azores.

This was also the third whale species located by Team 3. So as that infamous song went… ‘three is a magic number’! Great job Team 3!

So we now enter the home straight on this year’s expedition, and look forward to meeting Team 4. We have high hopes.

I leave you with a final set of pictures and some feedback from the team…

 

Azores: Team 3 in the swing of things

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

Team 3 is now well into the swing of things. After a whistle-stop weekend of introductions, briefings and training sessions, we were all eager to get on with the data collection. But initially things seemed against us: an injury, acquired just before the expedition, the weather, sea sickness, etc. However, the good news is that by today, not only have we already seen more common dolphins, loggerhead turtles and a fin whale, but the group also spotted the largest group of striped dolphins recorded so far by this year’s expedition (about 50). So stay tuned!
