Day 9


Our last morning started well with low swell and light winds making it perfect for sightings. But we were definitely feeling the effect of the cold Labrador Current even in our flotation suits.  We were aware that Humpbacks migrate to this area in great numbers but thought  it might be a bit early yet. However Humpbacks were visible all the way to St. Johns. We didn’t see any cetaceans other than the Humpbacks. The Canadian scientists said that they were feeding on fish called caplin. It was a fantastic way to end the first leg of the trip and makes the start of the next leg look very promising.

As we were quite close to the shore the numbers of birds seemed to increase drastically. We encountered 7 different species today the Glaucous gull, Herring gull, Fulmars, Kittiwakes, Guillemots as well as a return from the Gannets, and for the first time on the trip Puffins.

We pulled into St. Johns just after noon to complete what was a really good trip. The weather over the whole trip was much better than we expected. This led to us having lots of sightings of cetaceans as well as birds. We will be back on the ship for the return leg starting on the 2nd of June. We will continue this blog then and hopefully we will have plenty to report.

Day 8 Iceberg’s ahead.

This morning as we were going up to the crows nest we were told to keep an eye out for icebergs and growlers. Growlers are bits that have broken off the main iceberg and can be more dangerous as they are not picked up by radar. The conditions were good for spotting the icebergs with low swell and light winds making it easy to spot anything on the surface. The problem was the fact that it was very hazy and our visibility was limited to a few kilometres. Sure enough shortly after starting we got a call to say that an iceberg had been picked up on the radar. Not long after we could see it through the haze and it was big!

 Despite spending most of the day looking ahead of the ship we did manage to record a few sightings. On three separate occasions we spotted blows but they were too distant for a proper species id. Enda did manage to capture an image with his new shooting from the hip method of photography. I must admit that over the last few days this technique seems to be working very well. 



Numbers wise it was a quiet on the bird front today. But we still had 6 different species Kittiwake, Manx Shearwater, Pomarine Skua, Long Tailed Skua, Herring Gull and our old friends the Fulmars.

We should be in St. Johns shortly after midday tomorrow all going well so it will be our last day of sightings. Hopefully it will be full of cetaceans, birds and a few icebergs at a distance.

Day 7

The weather today was worse for sightings than it has been. Despite our best efforts we didn’t see and cetaceans during the day. We have been spoiled so far on the trip, so one day without sightings isn’t the end of the world. But hopefully it will be just the one day.

In the absence of cetaceans the birds received plenty of attention which wasn’t hard considering they were following us for most of the day as the crew were fishing. This paid off with us adding a new species to our list bringing the total number of bird species encountered to 13. The new species was the Herring Gull, the other species we saw today were Long Tailed Skua, Pomarine Skua and the ever present Fulmars.

Hopefully tomorrow the sighting conditions will improve and we will see plenty more cetaceans and birds.

Day 6

What a difference a day makes. In the last 24hrs the water temperature has plummeted from 15 to 40C and the depth went from 4000m to 200m as we moved out of the North Atlantic Drift and into the Labrador Current over the Flemish cap. After being spoiled with sightings over the last few days things quietened today with only two cetacean sightings and even then they were just blows in the distance so we could not confirm a species id.

The birds kept us busy for the morning with all three Skua species we have encountered making an appearance Great Skua, Pomarine Skua and Long Tailed Skuas. There were again high numbers of Pomarine and Longtails. We also had Manx Shearwaters and a Tern species which was too far away for us to identify to species level. The ever present Fulmars were around in great numbers and as if they knew we were going to begin fishing, were hanging around the boat for most of the day.

In addition to looking for birds and cetaceans we are also on the lookout for icebergs after reports from Canada informing us that they will be present along the rest of our journey to St. Johns.

Day 5


Today, like yesterday presented us with ideal conditions for sightings with small swell and light winds. Needless to say after a good day of sightings yesterday we were expecting another good day today. Our first sighting was of a group of 8 Pilot Whales. Seeing these has fast become a daily occurrence. However as we looked back over the photographs we had taken of the group we saw that there was at least one Bottlenose Dolphin in the group. Things then died down for a few hours until a blow was spotted about a kilometre off on the port side the animal only blew a few times before disappearing into the deep. Things really kicked off after dinner with 5 separate whale sightings with a total of 9 animals. This included at least 1 sperm whale which happily fluked for us when deep diving allowing us to get a photo.

During this time there was another group of 6 pilot whales which we photographed, and a group of 5 small cetaceans which were not willing to show themselves for a few pictures. The other sightings are proving more difficult to identify. The photo below gives a glimpse of 1 of the animals, if anyone has any thoughts on a species ID we would be happy to hear them.

For a while it seemed that all we had to do was look anywhere in the water and we would see something. The large numbers of sightings in the evening corresponded with an aggregation near the surface which was picked up by the echo sounder.

While the cetaceans were putting on their best showing so far the birds were more elusive and stayed clear of the boat making them difficult to identify. Even though numbers were down on yesterday there were still plenty of birds around including Great Skua, Pomarine Skua, Long tailed Skua, Fulmars and Manx Shearwater.
So here’s hoping for a similar day tomorrow with plenty of chances to see more birds and cetaceans.

Day 4 : What the Flock!


Today was by far the best day for sightings that we have had yet the swell had decreased further overnight and the wind had eased off. The improved conditions lead to almost instant results when shortly after beginning our watch we spotted a blow off in the distance. This lifted our mood instantly because it was the first blow we have seen so far on the trip, unfortunately it was too far off for us to id the whale. Things then got very quiet till we encountered a small group of about 8 pilot whales just off the port side as with the other two groups we managed to capture pictures of these as well. Then as the evening wore on and we began to talk about how perfect the conditions were we were rewarded with some more blows, first off to our starboard side and then far off on the port side. As we looked for further signs of these animals two more appeared much closer to the boat. Enda was quick to grab the camera and captured a few photographs of the whales. As the excitement died down and we began to think about dinner, another blow appeared off the bow of the boat. This was to be the final activity from the cetaceans for the day. After consulting with our esteemed colleagues the whales were identified as Northern Bottlenose Whales.

It wasn’t all whales today as we have added two more bird species to our list bringing it to 11. The day had started quietly with no activity in the air but this picked up as the day progressed and culminated in a large group of Pomarine Skuas as well as our new arrivals Long Tailed Skuas. The Long Tailed Skuas made a big impression with well over 150 of them passing us throughout the evening consisting of three large groups of 30-50 individuals and stragglers. All were headed east and seemed to be on a mission. The other bird sightings today were a few Great Skuas and a scattering of Fulmars, the odd Shearwater species and 2 groups of Tern species with up to 50 individuals each during the day.

Then just as we were packing up John Cunningham one of the crew spotted a large sun fish passing by in the water it was a nice end to an exciting day. Hopefully the weather stays the same and we see plenty more tomorrow.

Day 3

The clouds returned today which was probably just as well since I managed to get sun burned yesterday. The weather is improving all the time with the wind dying and the swell decreasing leading to better sighting conditions. Pilot whales were again flying the flag for cetaceans with a group of 16 appearing early in the day. Enda secured some good images of the group which was mostly adults with one juvenile. Things have gotten very quiet on the bird front with very few numbers seen today. We can add another to our list though after spotting a Pomarine Skua which brings the bird species count to 9. The other species we saw today were Fulmar, Gannet, Kittiwake, Manx Shearwater and Lesser Black Backed Gull. The crew conducted a trawl today to test the gear, it went quite deep and despite not catching much (a quarter of a bucket) it contained all manner of unusual species from the deep. We will be crossing the mid-Atlantic ridge during the night and with the weather conditions improving all the time hopefully there will be plenty to see tomorrow.

Day 1&2

Day 1: The first day began with us conducting our sightings from the bridge, weather conditions were not ideal  with sea state 6 for the day making it hard to observe cetaceans. However with assistance from the crew we did manage to see 3 common dolphins in the afternoon. Things on the bird front were better with 8 different species through the day Fulmars, Gannets, Kittiwakes, Great Skuas, Great Black Backed Gull, Lesser Black Backed Gull, Guillemots and a couple of Manx Shearwaters. We have moved off the continental shelf edge and are currently in waters that are three to four kilometres deep.  The bacon and cabbage dinner more than made up for a quiet day on the sightings front.  

Day 2: Unfortunately the sea state didn’t improve over night but we were treated to nice blue skies for the day and were able to conduct our sightings from the crow’s nest. Again we only saw only one cetacean species today, a group of 10 pilot whales that we encountered shortly after lunch. We managed to take some pictures including a few fin shots that may be used for photo-id. The birds managed to keep us busy again but were noticeably fewer in number than yesterday we had 6 species Fulmars, Gannets, Kittiwakes, Great Skuas, Lesser Black Backed Gull and Manx Shearwaters. We have our fingers crossed that the sea state will improve over the few days and give us better opportunities for spotting cetaceans. Failing that I’m sure the birds will still keep us entertained. The internet is pretty hit and miss at the moment but we’ll try and keep you up to date when we can.

Trans-Atlantic Blog

The R.V. Celtic Explorer departs Galway tonight  for a trip across the Atlantic to St. Johns in Newfoundland Canada conduct cod surveys for the Canada Marine Institute. A collaboration between the Irish Marine Institute and the Galway Mayo Institute of Technology will see Enda McKeogh and Paddy O'Dwyer (GMIT IWDG)  joining the cruise to record  marine mammals and bird sightings. We will also be on board for the return leg of the journey in June.

This trip provides an excellent opportunity to observe and record marine mammals in areas where there has not been much survey effort. We will be covering a large area with many different habitats including shelfedge, mid-ocean fracture, sea mounts and vast abyssal plains. This follows on from the same trip last year when Conor Ryan, Alessandro Pierini and Emily Wilson joined the cruise and returned with very valuable sound recordings and sightings data even though they faced harsh weather conditions on their trip. At the moment the weather looks favourable for us with easterly winds forecast for the next few days. This trip is expected to last 7 or 8 days depending on the weater we encounter so fingers crossed the weather gods will be our side!


In addition to surveying  we will be deploying XBT's and XCTD's which will record water temperature and salinity profiles across the Atlantic this information is being recorded for use by the Irish Marine Institute.

We will try to update this blog as often as possible to keep everyone up to date on the sightings we encounter during the trip. Hopefully the weather will be good and we will have plenty of bird and marine mammal sightings to report.
