Greenland -
2015
Greenland
is the world's largest island.. It is an autonomous territory within
the Kingdom of Denmark.
In
July-August 2015 we had a fantastic 57-day European trip.
(Melbourne - Dubai - Paris - Norway -
Spitsbergen - Arctic cruises - Iceland -
River Seine cruise - Dubai - Melbourne).
We had 2 Arctic cruises on the 120-passenger Sea Adventurer. On the second cruise we visited the
east coast of Greenland.
Greenland - Scoresby Sund
We spent 2 days crossing the Arctic Ocean from the Svalbard
archipelago, north of Norway, to East
Greenland.
While we were crossing the ocean we had lectures on history, whales,
seals, walrusses and geology.
Scoresby Sund (Scoresby Sound) is named after William Scoresby by his
son, also William Scoresby,
who were both British Whalers who plied the waters in this
region between 1817 and1812.
It is the longest fjord system in the world and consists of a network
of fjords for hundreds of kilometres.
The mouth of Scoresby sund is more than 50 km from north to south.
The most distant point, at the head of Nordvestfjord is more than 313km
from the sea.
There were large patches of pack-ice that the captain had to spend 3
hours slowly nudging his way through.

Arctic Hare
Arctic
hares feed primarily on plants but do also eat
mosses and lichens.
Female hares can have up to eight baby hares called leverets.
There is little information on the lifespan of Arctic hares.
Some anecdotal evidence suggests they live three to five years in the
wild.
Arctic hares do not survive well in captivity, living only a year and a
half at most.
Another
walk on East
Greenland
Musk Ox
The musk ox is noted for its thick coat and for
the strong
odor
emitted during the seasonal rut by males, from which its name derives.
This musky odor is used to
attract females during mating season.
Muskoxen primarily live in the Canadian Arctic and Greenland.
Ice Mirages
Ice mirages are a result of
temperature differences in the
bottom few metres just above the ice or sea surface.
Air of different temperatures refracts light in different ways, the
same phenomena is responsible for "heat haze" as seen above a road on a
very hot day.
It is the difference in temperature that is important and in
this
case it is causing a reflection downwards just above the level of the
horizon
so that objects on the horizon appear to be floating above
the
sea or ice rather than resting on it.
The blue stripe is the result of melt water
re-freezing when
the ice was part of the glacier.
It absorbs colour differently.
We
had a fantastic cruise on the zodiac this morning.
There were icebergs bigger than the ship.
We had planned to visit
this village, but the captain was
worried that the ship would become trapped by pack-ice.
Humpback
whales
Just
after breakfast we cruised through a pod of humpback whales.
They were all around the ship.
Humpbacks
are baleen whales whose diet
consists
mostly of krill and small fish.
Found in oceans and seas around the world, humpback whales typically
migrate up to 25,000 km each year.
Humpbacks feed only in summer, in polar waters, and migrate to tropical
or subtropical waters to breed and give birth in the winter.
During the winter, humpbacks fast and live off their fat reserves.
The
captain was worried about being trapped by ice if he entered the
fjords, so the decision was made
to cross the Denmark Sea to Iceland a day earlier
than planned.
