#20 Bay of Warmth (Part 5): GSL Right Whales!

This is Part Five of a series of posts about surveys taking place in the Baie de Chaleur in the southern Gulf of St. Lawrence. Click on the links to read Part One, Part TwoPart Three and Part Four!

After a beautiful afternoon with near ideal survey conditions we began our long trek from Bonaventure Island back to the Stonehaven dock. We encountered the (presumably) same fin whales again in the same area and continued our return in relatively quiet conditions. That is, until about 5:30 PM. We were traveling along the Quebec side of the bay and spotted a blow off the bow followed by a fluking dive. It was what we all had been waiting for: a North Atlantic right whale! This being the GSL team’s first sighting and all the excitement aboard the R/V Callisto was palpable. We quickly went into action exchanging our binoculars for cameras, recording time and coordinates, and keeping watch for it to reappear. We did not have to wait long for it to resurface and the rest of the sighting consisted of it curiously approaching our boat and diving at short intervals. We discussed the familiarity of its scars and callosity and concluded quickly that we recognized this individual: Catalog #1278.

First seen in the Great South Channel in 1980, this adult male has an extensive sightings history in every known habitat over the last 35 years. One of the most interesting realization we had was that he was photographed about 4 miles from this site close to a year before, and had been seen a few times prior in the Gulf of St Lawrence. With no dedicated right whale effort in the Bay of Chaleur it is possible that this and other whales visit this area more frequently than documented and that this habitat could be more used than we thought.

We had one more survey day the following Thursday before returning to Lubec, and had our second whale of the trip encountered another old male very close to our first sighting (~6 miles), identified as Catalog #1307.

This individual was first seen in 1974, and also has been observed in every known habitat over its 40 year sightings history. He actively avoided our boat, which may shed some light as to why he bears far fewer scars than #1278.

Unfortunately high winds on Friday and Saturday prevented us from another survey prior to leaving. Given that both whales we observed were swimming into the Bay of Chaleur it is quite possible that more whales arrived after we departed. Hopefully with more effort and data collection we can figure out the significance and usage of this bay to North Atlantic right whales.

#19 Bay of Warmth (Part 4): Gannets Everywhere

This is Part Four of a series of posts about surveys taking place in the Baie de Chaleur in the southern Gulf of St. Lawrence. Click on the links to read Part One, Part Two, and Part Three!


While hauling the R/V Callisto, Alex noticed an adult northern gannet with limited movement at the boat ramp. Upon approach he saw that there was a hook stuck in its wing with line originating from its mouth; the line wrapped the wing in such a way that it could not extend it and who knows how long it had been entangled like this. We knew that we had to do something to help this individual.

We promptly devised a plan to safely secure the bird and gathered the appropriate tools (gloves, wire cutters, towel and sunglasses as safety goggles) to remove the hook and monofilament line. Alex blocked its access to the harbor and distracted it so Monica and I could carefully capture it.

We successfully cut the hook and removed as much line as we could, and were happy to see the gannet flee to the water with its wings lifted.

On Tuesday, August 25th, we had a great forecast so decided to travel to the northern opening of the Bay of Chaleur in an attempt to make it as close to the Gaspé Peninsula as time and weather would allow. We encountered some fin and minke whales, but other than that the survey was relatively quiet. We reached Percé in the afternoon and stopped for a quick lunch break and to take in the beautiful views.

Here we got to watch northern gannets on Bonaventure Island, the largest colony in North America.
Males are competitive for prime nesting sites and are the principal nest builders using mud, grass, seaweed, and feathers. Northern gannets are monogamous and long term pairs often use the same nest for years and potentially mate for life. Both parents incubate the single egg and are active in feeding the chick.

It was amazing to see the white bodies crowding the cliffside and the active scene on the island and in the air. As we watched the gannets on and around Bonaventure we pondered (and hoped) that the one we had helped earlier in the trip was there and reunited with its mate. After this refreshing break we continued our tracklines back towards our dock and scanned the water for what we had come to find- a right whale.

#17 Bay of Warmth (Part 2): Lets Get on the Water!

This is Part Two of a series of posts about surveys taking place in the Baie de Chaleur in the southern Gulf of St. Lawrence. Read Part One here.

Once we arrived in our temporary home of Janeville, New Brunswick we quickly went to work getting things ready for survey.  We unpacked, set up equipment, launched the boat, checked the weather and met about various trackline strategies.  Even though we were in an area completely new to us we had some advantages.   The biggest advantage was that we had colleagues in the general vicinity conducting aerial surveys for right whales. We hit the ground running with one day on land followed immediately by three long boats in a row.

With such a small team we had no breaks while on the water.  We rotated from two hours of observation to one hour at the helm and back to two hours of observing.  In addition, we had no dedicated data recorder which meant driving and recording was done by the same person.  This was challenging in rougher sea states.

Our first three days on the water were productive.  We didn't see any right whales but we felt good about our efforts.  Logistically speaking things were going great. We logged many miles of trackline data right from the start. We were quickly learning about the local wharfs, boat ramps and weather patterns of the area.  We felt confident and well seasoned, now we just needed to find some right whales.  Each morning brought new anticipation, excitement and a bit of nervousness.  With only eight boat days of survey budgeted each day without whales brought a new sense of urgency to our time.

#16 Bay of Warmth (Part 1)

If you are one of our many avid blog readers you will know that the past few years in the Bay of Fundy have been pretty sparse in right whale numbers. Last year, things looked hopeful when we first arrived in the field. Our first two weeks proved very busy and right whale sightings were common. However, after two weeks things turned desolate and right whale sighting became more rare for our team working in the Bay of Fundy and offshore (of Nova Scotia) on Roseway Basin.

The first right whale spotted during the 2014 field season.

Coming out of the field last year, as with the previous couple of years, we asked the same question: What can we do different next year?

This year we did do something different. Picking up and moving a field team is not easy. Doing something different from the 20+ years is also not easy. There are so many road blocks and logistics that must fall into place (funding, people, equipment, boats, housing and insurance to name a few) to take a small team into the field and into an area you have never studied before. However, that is exactly what we did. It was an exciting time and I'm excited to share it with you (over the course of a few blogs).

The second half of August I lead a small team into the field with the goal to collect boat-based survey effort in an area of the southern Gulf of St. Lawrence. The main focus was a small bay called Chaleur Bay (or Baie des Chaleur in French) which translates into the "bay of warmth."  Historically, there have been a scattered number of sightings in the Gulf of St Lawrence. In the past two to three years there have been an interesting number of whale sightings (mostly single whales) seen in the Baie des Chaleur. Since we had limited time (2 weeks), limited people and a limited boat (day trips only) we decided (sometime in the winter and while Boston was hidden under multiple feet of snow) that the Baie des Chaleur had enough opportunistic sightings to warrant a small expedition in the summer of 2015.

Our Baie des Chaleur expedition started as most do, in a very non-glamorous manner. From Lubec we drove to Boston to rent a heavy duty truck for towing, pick up the R/V Callisto and headed to northern New Brunswick via Lubec.

The team was small and included myself, Brigid McKenna and Alex Loer.

 After three days of driving we finally arrived in the Bay of Warmth!

 We rented a little cabin in Janeville, New Brunswick, Canada to serve as our home base for two weeks.

The next step was to hit the water and look for whales! More to come here on the blog, stay tuned.

#3: Meet Brigid!

This season we've invited new faces to the team to introduce themselves and provide a little background on what led them to our research program. First up is Brigid!
--------------
Hi! My name is Brigid McKenna and I am one of the seasonal research assistants on the NEAq right whale team. This is my first full field season here in the Bay of Fundy, though I'm not completely new to the team. Last year, I helped out on the R/V Nereid for a few weeks shortly after I finished my masters at the University of St Andrews


Brigid and Walter (dog pictured at left) have been a wonderful addition to the team.
I started participating in marine mammal research in 2010 through Whale &Dolphin Conservation (WDC), with a focus on Gulf of Maine humpbacks. Since then I have been involved with another humpback research program at the Center for Coastal Studies (CCS), spinner dolphin work in Hawaii through the SAPPHIRE project (Duke & Murdoch Universities), and have recently been collecting data on right whales at CCS on both vessel and aerial platforms. I am really excited to be back in Lubec this year with my dog, Walter, and ever more stoked to be going out on the water to see right whales in this habitat.
