A Few Hours at Sea

As part of the daily routine aboard a whale watch vessel, I get to experience many things, both on the water and on board, while also recording what I see and taking photographs of whales and sharks for photo-identification purposes. The database can give a snapshot of daily and yearly views of a portion of the Bay of Fundy and can be helpful for others who can't be out as often.  Photo-identification of individuals are added to the appropriate catalogues to follow individuals and learn more about them.

In a few short hours, we can sail to a feeding area for seabirds, whales, seals and fish and experience a glimpse of an amazing ecosystem and share this with our passengers. The weather can change from restricted visibility to clear and from swell to calm seas. On July 28th, we got to experience all of these plus helped remove some threats to the marine animals and have a bit of a laugh.

We began by retrieving a poly-balloon used by fishermen to mark their fishing gear with 100 m (300') of sinking rope. The poly balloon and line had broken off its intended fishing gear and was drifting in the current.  This loose line is dangerous to a whale because of risk of entanglement. Given the growth on the rope it had been floating for awhile. It is always best to remove loose gear to prevent this hazard.  Sometimes it can be returned to the fisherman if there are identifying marks but not in this case. We then found a huge bunch of party balloons for someone's Sweet 16 birthday. When helium balloons are released they travel up into the atmosphere and are carried toward the coast.  The air is cooler along the coast, some of the helium escapes, and the balloons usually descend into the ocean where they float on the surface mimicking jellies.  They are mistakenly eaten by turtles and even whales and can cause the death of the animal from blockage.  It is a sad way to die.  Even though it looks pretty to see the balloons rise into the air, there are deadly consequences and this practice should always be avoided.

During the sail, we see numerous seabirds.  These birds are well adapted to life at sea.  Sooty shearwaters, for instance, only return to land when they are nesting in the southern hemisphere and even then they may spend days foraging before returning to the nest.  Their long, narrow wings allow them to glide effortlessly, particularly when they are close to the water surface which is where the term shearwater comes from.  They are in the tube-nosed bird family which also included albatrosses, petrels, fulmars and storm petrels.

Some seabirds are very tiny but yet still spend their lives at sea, except for nesting.  Red-necked phalaropes are one of those small species, a shorebird who gave up the shore.  They are often found along tide streaks where seaweed accumulates, providing shelter for small zooplankton which the birds eat.  These female red-necked phalaropes are on their way to their non-breeding area in South America and stop in the Bay of Fundy for about three weeks to double their weight and continue their journey, after laying eggs in the Arctic.  They do not incubate but leave that to the males.  Some of these females still have their breeding plumage which gives them their name.

Not all of the members of the whale family are large either.  This harbour porpoise calf, born in June is only about 100 cm in length. Still staying close to its mother, they do venture a few metres away at times.  Its small size is apparent when compared to the great shearwater.

The Bay of Fundy has some very interesting oceanography and the whales and seabirds are aware of times and locations of ready prey availability which change each day according to the lunar cycle.  If you arrive at the correct time, the observations of whales and seabird feeding can be spectacular.  Although food can be abundant, the birds often fight over a fish.  This herring gull appears to be winning the fight, only to be attacked by a great shearwater, also intent on swallowing this herring.  Bite marks can be seen on the fish.

 The feeding aggregations can have many species including minke, finback and humpback whales, harbour porpoises, and harbour and grey seals.  While photographing this minke whale, I was also fortunate to capture a harbour porpoise with its head fully out of the water.  They are often swimming so quickly that they partly propel themselves into the air when breathing.

Finback whales are slower to surface, given their larger size, and with the right lighting conditions, more of the whale can be seen underwater.  Finbacks have an asymmetrically coloured face with the right side of the jaw being white and the left grey.  This photograph show that.

We finished the trip by being entertained by one of our passengers who brought his pirate costume along.

All in all, the Bay offers some amazing sights and with often calm seas in the summer, these can be enjoyed by all.

off Grand Manan Island
Ashley Heinze contacted me in January to see if there was any chance of staying at the GMWSRS during the summer and collaborating with one of the whale watch companies to conduct surveys and collect whale behaviour data. Our research field season wasn't beginning until August this year so the accommodations were available in July.  Ashley planned her time accordingly, arriving the end of June and has been coming with Whales-n-Sails Adventures on most trips.  It has been a pleasure to be of assistance, both by providing accommodations and also helping with the data collection on board.  We are always happy to collaborate with others when possible.
I asked Ashley to provide a profile of her academic background and interest in marine biology:

The first time I saw or even placed my feet in the ocean I was twelve years old and ever since then the big deep blue has fascinated me. I was never solely focused on marine mammals, although, they did interest me.


During my undergraduate career I tried to explore many aspects of the marine biology field. I was always looking to be involved in hands on or field research to gain as much experience as possible. I first began entering data for the Census of Marine Life at the University of Rhode Island Graduate School of Oceanography and at the same time I began volunteering at Mystic Aquarium and Institute for Exploration. While at the aquarium I had the opportunity to be an exhibit interpreter for two years and then a husbandry assistant for another two years. To gain a greater amount of field experience I worked under two graduate students at the University of Rhode Island, one from the Wilga Lab and one from the Thornber Lab. While working for the Wilga Lab I was able to help with the Kinematics of Spiny Dogfish, Squalus acanthias, the function of the dorsal fin in bamboo sharks and the functional morphology of the dorsal fins in sharks during steady swimming and maneuvering. The Thornber Lab allowed me to expand my knowledge of the distribution of algal communities in Rhode Island.

 College of the Atlantic
When studying abroad in Australia I gave my future education and career a great amount of thought. After traveling around the country I started to begin questioning different tourism activities. How much does the activity change the behavior of the animal involved and how much does the activity affect the people involved? I began to ask myself what tourism activity is growing in North America then I thought whale watching. College of the Atlantic in Bar Harbor, ME has allowed me to create a project in which I am able to look at both of these questions. In collaboration with the Bar Harbor Whale Watch Company and Whales-n-Sails Adventures I am able to compare the two whale watching areas. I am comparing the knowledge and attitudes of whale watching passengers before and after the whale watch trips. I am also looking at the differences and similarities between the whale watches in Grand Manan and Bar Harbor and comparing whale behaviors during these trips. Whales-n-Sails Adventures and Bar Harbor Whale Watch Company have donated trips to me when space allows. I currently have two field assistants this summer, Kathryn Scurci and Jessica McCordic, both are in Bar Harbor collecting data while I am here on Grand Manan. Since my assistants were not able to be here on Grand Manan, Laurie has graciously offered to provide me with photos taken from each trip that will be used for photo identification.

I am having an amazing time here on Grand Manan and eagerly look forward to my remaining time here on the island and collaborating with Whales-n-Sails Adventures (http://www.whales-n-sails.com/). This was my first visit Grand Manan and I know it will not be my last!

Visiting Master's Student

Ashley Heinze is staying at the GMWSRS for the month of July as part of her Master's research.  She attends the College of the Atlantic in Bar Harbor, ME.  Her supervisor, Sean Todd, is a long time colleague and it is a pleasure to offer the opportunity for this collaboration.

for Whales-n-Sails Adventures.
Her thesis is comparing attitudes and knowledge of whale watchers before and after a whale watch, similarities and differences between whale watches in Bar Harbor and Grand Manan, and whale behaviour during whale watches.

Her first three whale watches have been very different, with many more to come.  Whales-n-Sails Adventures has graciously offered free trips where room allows, as a whale watch company in Bar Harbor.  Any photos that she needs will be provided from my selection taken daily and to be used for photo-identification.
