Escorting ships in fog through ice is a difficult task.  Finding the easiest and safest route through the ice is challenging.  Yes, radar helps, but it's not as good as the Mark I Eyeball.  It's also hard to find the ridges (Windrows on the Great Lakes).  In the Arctic these can be significant size and hardness and can stop an icebreaker dead in its track.  That means the cargo ship following must do all in its power to stop or avoid a collision with the icebreaker.
 Several views of the Kivalliq W in the ice.

Fairly close escort.  The icebreakers will frequently work within 20 metres of a ship to free it from the ice.  Both the Captain and the Quartermaster (wheelsman) must be good.

Below:  CCGS Terry Fox.  Canada's 2nd most powerful icebreaker.  
As Canadians will know, Terry Fox the person, was an heroic figure.  With an artificial leg he ran a marathon a day, aiming to cross the country (Canada), to raise money for cancer research.  That's a 5,300 mile run.  Sadly, he only got halfway across before succumbing to his cancer.  More on Terry Fox and the Marathon of Hope, Click Here.

I have no idea why or what president it refers to.

July 2, 2019. CCGS Des Groseilliers escorting MT Kivalliq W in Frobisher Bay

Below:  Tanker Kivalliq W following the DesGroseilliers through the ice.  This is July 2, just below the Arctic circle.
Kivalliq W is operated by Coastal Shipping of Lewisporte, Newfoundland, Canada.

Kivalliq W

Kivalliq W
Net Tonnage:  4617;  Displacement Lightship:  4941t;  Displacement Summer:  18611t
Ballast:  5857t;  Bunker:  607t;
Crude capacity:  100,115 bbl;  Liquid oil:  16,300cubic metres;
Cargo Pumps:  14 at 330 m3/hr
Above & Below:  From the helicopter.  In order to determine the best route through ice, and to map ice conditions, helicopters are used.  Crew of the helo while in flight is Pilot and Ice Service Specialist (in my day known as The Ice Pick).  There is also an aircraft engineer on the ship who services the aircraft.  The Ice Pick will make a detailed map of ice conditions while airborne.  This information is used by the Captain to determine the best route to follow.  The information is also sent to Canadian Ice Services for inclusion in daily ice charts that are promulgated to anyone interested, and are available on the web.

Below:  Example of an ice chart.  Red is bad, blue is water.  About 1/3 from the bottom on the left is Frobisher Bay with the city of Iqaluit near the head of the bay.
At the bottom of the chart is a legend that shows concentration in colours.  For example, orange is 7-8/10.  This means the area shown in orange has between 70% and 80% ice cover.

Above:  A rather large floe of rotten ice.
More views from the helicopter.

Rather stark country.  Not suitable for farming.

June 22, 2019, CCGS / NGCC Des Groseilliers departs Quebec City for the Arctic

Each summer the Canadian Coast Guard sends its fleet of icebreakers to the Arctic to support shipping, carry out scientific research, engage in Search & Rescue and any other tasks that may be assigned.
CCGS Des Groseilliers was initially designated as a 1200 class icebreaker.  It is named after Medard Chouart des Groseilliers, a close associate of Pierre-Esprit Radisson.  Both men were involved in explorations west of the Great Lakes and in the founding of the Hudson's Bay Company. The ship entered service in 1982.

Below:  Tanker Limerick Spirit, one of the many ships seen daily on the St Lawrence river.

The sister-ship, CCGS Pierre Radisson, is currently at the shipyard in Port Weller, Ontario; just above Lock 1 of the Welland Canal.  Both the Des Gros and the Radisson have been to the Great Lakes to assist with spring breakout and ship escorts.

Length:  98 m (322 ft);  Beam:  20 m (65 ft);  Draft:  7.5 m (24.5 ft)
Ice Class:  Arctic Class 3

Propulsion:  Diesel Electric
17,580 shaft horsepower (13,110 kW) and six generators creating 11.1 megawatts sustained, 
powering two motors that, when driving the shafts, create 13,600 shp (10,100 kW).

Speed:  16.5 kt
Range:  30,600 nautical miles
Endurance:  108 days

Below:  Unlike many other coast guard aviation units around the world, the primary role of the Canadian Coast Guard's helicopters isn't search & rescue (SAR) - that role falls to the Royal Canadian Air Force.  CCG helicopters can, and do, assist with SAR taskings if called upon, but they primarily serve to ensure the safety of marine traffic, largely through the construction and maintenance of navigational and communication aids that are only accessible by air.

Additional responsibilities include the support of Coast Guard icebreakers in the form of aerial reconnaissance, environmental response, supporting ongoing scientific research projects.
