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.

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…

After a whistle-stop weekend of introductions, briefings and training sessions, our new team were probably not expecting fish food and ‘rock ‘n’ roll’, as they set foot onto the Physeter – our research vessel.

The whales were playing ‘hard to get’, and the dolphins were a ‘no show’ for whole afternoon at sea. We eventually tracked down two fin whales, whose constant diving made them even harder to locate in the rise and fall of the large swell. As the boat pitched, rocked and rolled, any romantic notions of cetacean watching in calm sun-kissed seas quickly evaporated from the minds of many – replaced with the nauseous reality.

Momentary distraction and the highlight of the day came in the form of a captured loggerhead turtle. This sizeable specimen was tagged (in the hope of recording future movements), vital statistics taken and returned to its ocean home.

So a tough first day ’at the office’ with cetaceans hard to find, but the silver-lining was the first turtle tagging of this year’s expedition…and the fish also got fed (more than once)!

Expeditions are about taking the rough with the smooth, and hopefully we’ll get the latter soon…

In the meantime an article about our work on the Azores has appeared in a major Portuguese newspaper http://observador.pt/2015/04/19/vida-selvagem-mergulha-nos-acores/ and we hear that supremely dim Pippa Middleton reports having eaten whale meat http://www.wildlifeextra.com/go/news/Pippa-Middleton-whale.html#cr….

So our first slot of 2015 in the Azores has come to an end, and it only seems like yesterday that we started.

It is amazing what you can pack into just a few days when you try. We’ve been lucky to encounter four species of dolphin – Risso’s, common, bottlenose and false killer whales. The last three numbered in their hundreds over our five survey days.

And as for the whales…. the blue whale was a great way to kick-start the surveys – any day you encounter the largest species that has roamed our planet, has to be a good day. We’ve had breaching humpbacks and sperm whales, and several encounters with the elegant fin whales.

The team also broke a record, documenting the highest number of loggerhead turtles by any Biosphere Expeditions team, and we also completed the set with a leatherback turtle record.

A great team, all doing a fantastic job, and all the encounters equate to vital data. What more do you want from a week at ‘work’?

Safe travels and enjoy a well-earned rest.

Until next time….

It was inevitable that it would happen eventually, the last day of our first expedition at sea.

The team are now working like a well-oiled machine – arisen, eaten and out the door with time to spare when we arrived at the harbour.

We set off with the sea as calm as a pond. Our first encounter of the day was with a couple of pods of common dolphins who kept us busy for half an hour; then over the radio came sightings of blows off yonder.

We headed towards the island of Sao Jorge and arrived to see a fin whale, no two fin whales; no, three fin whales – who delivered great dorsal fin shots for our photographers (Lisa & Simon). Though it is always nice to get the ID and artistic shot!

We parted ways and headed off to investigate the blows of a potential sperm whale sighting. As I was doing the data sheets today, I can assure you they were indeed, but not just one – there were 23 sperm whale encounters and up to 43 individuals including calves!

The day was rounded off with seven female sperm whales in a line, side by side when an enormous male came into view and made himself known. Some of the females disappeared and one of them breached out of the water causing a tremendous splash before the male and the remaining females dropped below the surface.

We could not have hoped for a better ending to the day and the first group of 2015.

Bad weather stopped play. Our surveys were curtailed by the winds, but it did not stop the work. Saturday brought a day of data sorting, image matching and cetacean naming.

The team were introduced to the process of image sorting, matching tail flukes and giving our study subjects some form of identifier. Image processing and specially designed fluke matching software aid the process, but there is no substitute for a keen eye when it comes to trying to identify sperm whale flukes by matching them to previous records.

The Risso’s dolphins are identified by the marking on their dorsal fins, so a creative mind and an ability to say what you see, definitely helps in giving them a recognisable name.

Sunday was a well earned day off, giving us a chance to explore our temporary home town of Horta, and the wider island of Faial. Tomorrow we are back out on the ocean.
