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.
