#21: Roseway by Air

With the Bay of Fundy season coming to an end, we were all excited at the prospect of a final chance to see if anything had changed while we were waiting on land for the weather to cooperate. While the Shelagh crew was making plans to check out the Bay, the main cause for excitement was the promise of a long-awaited aerial survey, as the stars of weather, airplane and crew had finally aligned: we were going to see Roseway Basin from the air! The plane we used is a Cessna Skymaster O-2A - a military plane with a push-pull configuration that has seen some action in times of war, and such a cool looking aircraft that enthusiasts always comment on it!

Preparing for an aerial survey is much more complicated than preparing for a vessel survey, but once the team was given the green light, things swung into action quickly. Two NEAq observers- Orla and myself- met up with our two pilots, Dan and Don, in Bar Harbor ME on the evening of Friday, September 27. The plan would be to survey on Saturday, sleep in Yarmouth, Nova Scotia that night, survey on Sunday and then head back to Bar Harbor.

Conducting a survey from a plane is different from a boat in many ways. The plane is small and holds four people- there's only so many ways you can shift your body. Everyone in the plane has passed a ditch training course so that you know what to do in case of an emergency landing (and because of the water temperature during these flights, we wore an immersion flight suit and a life vest the entire time, adding to the difficulty of getting comfortable). We flew at 1000 feet in the air, and were shuttled around at 100 knots as opposed to 12 knots at sea level, so we needed to make a species count and identification quickly. Photographing from the plane is also a challenge- the pilot opens their window, banks the plane hard as you aim the heavy, long lens through the space, and there's about 10 seconds to get your shot before you've passed the target. But, there are plenty of perks to seeing the ocean from the air- covering a huge amount of ground in a short amount of time, observing behaviors without influencing the animal, and seeing all those creatures under the surface that you have a slim chance of seeing from a boat. Aerial photographs of whales are an important part of our research as well, since they offer a complete view of the animal's body.

As the morning sun peeked over the horizon on Saturday, we made our way to the airport near Bar Harbor. Our plane was pulled out of the hangar and our preparations for the flight began. The first leg of our trip would involve setting up to survey- flying to Yarmouth to fuel the plane, clearing with customs, and relaying our flight plans to the FAA and MAFF. We took off around 8 AM and got beautiful views of Mount Desert Island and the surrounding islands before continuing over the Gulf of Maine.

After landing in Yarmouth, we had to rearrange some equipment. The airport staff was incredibly kind and welcoming, and let us safely store our personal gear that was unnecessary for the flight. With our plane fueled up, we got into the air to begin our tracklines west of Nova Scotia, covering Grand Manan Banks and Lurcher Shoal. Before we even began our first trackline, Orla sighted two right whales- Van Halen (Catalog #1146, seen on Roseway Basin earlier this season) and Marble (#2602)- engaged in a surface active group (SAG). We circled over them and were able to photograph these two older males socializing in the calm sea.

A few minutes after we left the two right whales, a third right whale was sighted swimming under the surface, but we were unable to photograph it because it was difficult to resight and we couldn't invest much time looking for it- with our survey starting off with a bang, we would surely come across other whales to photograph. Yet, by the end of our second trackline (each trackline was 70 nautical miles long!), we had not come across any other right whales. We landed for lunch and fuel, and were back up in the air in under an hour. After completing two more long tracklines, we hadn't added any other rights whales to our sighting log. Feeling good about the amount of ground we had covered, we landed in Yarmouth, got a taxi to our hotel, ate dinner and worked on the data we had collected.

On Sunday morning with another early departure planned, our taxi driver was kind enough to make a stop vital to the success of our survey: Tim Horton's for coffee! With the plane and ourselves properly fueled, we worked on other preparations as we waited for fog in the surrounding area to move. Once the ceiling had lifted, we got into the air and began a new set of tracklines, covering Roseway Basin from east to west. We saw lots of sharks in the morning- mostly basking sharks, but some white sharks! As we neared the end of our third trackline, two right whales were sighted and we were able to photograph one of them- Crater (#1609), a male born in 1986.

As we landed for lunch, we reworked our tracklines to cover the most ground we could with the few hours we had left. We were able to survey the rest of Roseway Basin and part of Brown's Bank, and found a small cluster of right whales! There were five or six whales within a mile of each other, and two of them were belly-to-belly in a SAG.

We landed in Yarmouth to refuel and load all of our personal gear back on the plane. Crossing the Gulf of Maine once more, we made a stop at the airport in Bangor, ME to clear with U.S. Customs before flying to Bar Harbor. We were happy to shed our flight suits as we started unpacking our equipment from the plane and loading it back into Orla's car. The rest of the night was spent doing data, and sleep came easily once we were done!

These two aerial surveys were conducted later in the season than we originally intended, but still provide a critical puzzle piece to this year's unique season. We are hoping to run another survey this fall, and will be surveying by air again next year. In conjunction with our vessel surveys, we can gain a more complete understanding of how these waters are used by right whales throughout the summer and fall seasons, and if next year proves to be as challenging as this year, covering as much ocean as possible in the search for these whales will be incredibly valuable.

#20: When It Rains, It Pours

There is nothing quite like falling asleep to whale blows and then waking up to them in the morning. We had an amazing second day out on Roseway Basin and our third started out with dozens of scattered whales all around us. Some appeared to be feeding, so we spent the morning bouncing back and forth documenting as many whales as we could. We finally got back on our trackline just before noon, only to veer off of it soon after with more whale sightings. At one point we picked up two whales rolling around with each other, who we later identified as Catalog #3893 (a six-year old female) and #3570(a nine-year old male).  They were fairly preoccupied, so we were able to get a good close approach.

Not long after we snapped some shots of our two SAG-ing whales, we picked up a sighting that every whale researcher dreads: an entangled right whale. We tracked along with Catalog #3946 (a four-year old female) for the majority of the afternoon, with a handful of disentanglement attempts. Another blog will be posted in the next few days with more details on the entire disentanglement effort and the whale at the center of all the attention.

In the early evening we came upon a mom/calf pair!  This was really exciting since only two out of the 20 calves born in 2013 have been photographed since the spring in Cape Cod Bay, plus mom/calf pairs are an uncommon find in Roseway Basin. We identified the mom as Catspaw (#1632) and calf, the former of which has a unique sighting history.

Catspaw was first seen in 1986, but then went 12 years without a sighting from 1988 to 2000, so she was presumed dead for the majority of the 90s before being “resurrected” in 2000.  If a right whale has not been seen in six years, it is presumed dead until it is resighted alive or matched to a carcass. Every once and awhile these “presumed dead” whales reappear and with much glee are given the fitting status of being “resurrected.”  Since 2000, Catspaw has had three calves, with her current calf raising that count to four.  Her second calf (Resolution, #3532) was the first ever documented right whale birth, which happened to be photographed by our aerial survey team off of Florida back in 2005. It is also interesting to note that Catspaw is not a regular visitor to the Bay of Fundy (BOF), except during her calving years. Perhaps the lack of food in BOF this season has drawn her to other feeding grounds, which makes sense considering her calf is plump and sporting an incredibly large fat roll behind its head.    


After a long day of working whales plus some weird lighting, the calf looked a bit strange on our first approach.  Photo by Kelsey Howe

To top off our unique and busy day, our last sighting before sunset was a blue whale. Since our crew does not normally encounter blue whales in BOF or Roseway, it took us a few surfacings to correctly ID the species. Blue whales are the largest known animal to have ever existed, measuring about 100 ft for an adult. We were able to identify the species by its small dorsal fin, which is located so far back that it was only visible when the whale fluked during a terminal dive. When we got back on land, we sent photos of this individual to Richard Sears of the Mingan Island Cetacean Study, an organization known for their long-term studies of blue whales. Richard was able to match this whale to a cataloged adult female of about 70 ft in length, who has been seen foraging in regions south of the Gulf of St. Lawrence (including a 2006 sighting in BOF), which are the typical stomping grounds of northeastern Atlantic blue whales.

By the time the sun set in the west, we were exhausted, yet exhilarated by our day full of whales. We ended up photographing 20 right whales, with many more in the area (undocumented because our priority in the afternoon became the entangled whale.) In the last two days out on Roseway, we more than quadrupled our right whale count for the entire season, which is pretty cool.  

Stay tuned for our third blog from this Roseway trip to learn about entangled whale #3946 and our disentanglement efforts.

#19: A Cornucopia of Whales

Knowing that our weather window for our third offshore trip was one to be grasped quickly, the Shelagh team left the dock in Campobello Island around midnight on Tuesday, September 17 and transited across the Bay of Fundy overnight. When our team of five researchers awoke for sunrise on Wednesday, we were close to German Bank, southwest of Yarmouth, N.S. Our first day of survey passed by quietly, as the only large whales we sighted were three humpbacks and three fins. As we neared the southwest corner of our survey box for Roseway Basin, the sun had neared the horizon, and we left ourselves to drift under the brilliant Harvest Moon as we rotated through night watches.

On Thursday morning, we motored the short distance back to where we ended watch on Wednesday evening. Just before 9:00 AM, we photographed one right whale that we identified as Catalog #1239, but another three hours passed until our next right whale sighting. Our excitement grew as we monitored our position- we were nearing the "honey hole" of Roseway Basin, which has historically held high numbers of right whale sightings. It took us another five and a half hours of patient surveying until we finally found that pot of honey, but never has a horizon full of right whale blows been so sweet.

We got right down to business with a surface active group (SAG) of 10-15 individuals, and at the center of attention was Phoenix (Catalog #1705). Phoenix is so-named because of her recovery from entanglements, and is a successful reproductive female who has birthed four calves, an inspiring story that makes her a fitting whale for our sponsorship program. Her most recent calf was born just last year, which is potentially why she appeared to be grey and have poor skin condition- nursing a calf for months while the mother herself fasts drains her resources. After weaning the calf, there is usually at least one year of "resting," and ideally during this time period the female will regain blubber reserves and a better body condition before becoming pregnant again. The whales did appear to be feeding, so hopefully Phoenix was also finding plenty to eat.

A plankton tow in the evening revealed lots in the water column! 

We stayed with the SAG until it broke up about half an hour later, and then moved around to try to document other whales in the area that we hadn't already captured in our data. There were whales in all directions and distances, and we worked until the light was so low that we couldn't photograph anymore.

Even though our cameras were put away, we stayed on deck to listen to the whales that were blowing around us. We felt so lucky to be watching right whales off the starboard, fluking in an orange sunset under Venus and Saturn, while off the port side, whales swam under the full moon and Uranus.

A beautiful way to reflect on our successful day! Photo: Marianna Hagbloom

We slept well that night, and it was a good thing, too. The following day would turn out to be our busiest day of the year—possibly our busiest day of the past two seasons! We'll be following up with all the details soon...

#18: Soccer Shenanigans

When weather keeps us on land and the lack of whales/internet problems frustrate us to no end, all that pent up energy needs to go somewhere; therefore, a common August pastime is a good, friendly game of soccer to liven up Lubec life.  Soccer captain and "professional" player Philip Hamilton will rally the troops (sometimes a group as small as 4 or as large as 14), and we will all head over to the high school soccer field.

We improvise a bit without proper goals (water bottles for goal posts) or sidelines (no out-of-bounds), but that is all part of the fun! We regard rules more as guidelines (we are scientists after all!), so usually halfway into the game, certain people start using tactics more commonly witnessed during a game of rugby, hockey or wrestling.  But major injuries are few and far between, so fun is had by all.

During the last week of August, when several families of team members were in town visiting, we marched over to the field and had a great game that was generously photographed by Bill McWeeny.  We thought you all might enjoy a look at what we do to keep spirits up and laughter plentiful.

#17: Battling the Weather

The month of September brings a minuscule amount of good weather for vessel surveys, so whenever we are presented with the opportunity to log some hours on the water, we take it! Our teams set out on both Saturday and Sunday for partial survey days, running as long as we could until the winds made the seas unworkable. If the amount of hope and eagerness our teams hold could drive right whales into the Bay, we'd be up to our ears in sightings. Unfortunately, like the good weather days, right whale numbers continue to be minuscule, as we did not have any sightings this weekend to boost our current tally (by our team: seven sightings in the Bay of Fundy, an additional four on Roseway Basin).

We did, however, observe a sperm whale on both Satuday and Sunday, and we listened to its clicking using our hydrophone. This was the first sighting by the team for the season, but we had heard reports of a sperm whale in the Bay earlier this August. This marks the fourth year in a row that at least one sperm whale has been seen in the area.

Humpbacks were also spotted this weekend, and we were able to photograph one large humpback with some very peculiar wounds on its body. We'll be sending the images to an expert and the curators of the Humpback Catalog, who may have an idea of who this whale is and how it got these markings.

On Wednesday, the Shelagh will once again make its way offshore with five researchers and Captain Joe. This trip will take us to the mouth of the Bay of Fundy, Roseway Basin, Browns Bank and perhaps even the Northeast Channel- the survey plans are likely to change with the weather. The Shelagh will probably hove to at sea most nights, but dock in Yarmouth or Cape Sable Island, N.S. when needed, and be away for 6-10 days. Hopefully the weather will cooperate as best as possible- we're all interested to see what's out there!
