CGC HEALY passing through an area of first year ice floes with the sun directly astern.

Ice floes, melt ponds and a golden sun.

Sun seen through the clouds. Sunrise or sunset?

Reflections off grease ice that has formed in a polynya.

Frazil ice seen through the fog in a polynya.

A sun pillar seen above the pack ice fringing a polynya.

Reflections on grease ice with a few small floes.

Sun seen through the clouds over first year ice floes.

A helicopter view of the refreezing of ice flows and melt pools. By early to mid-September the refreeze has begun.

A lead through the pack ice. The outlines of refrozen melt pools can be seen in the pack ice. Interlocking fingers of nilas ice can be seen in the ice forming in the lead.

Rafting and interlocking sheets of nilas ice in the refreezing lead.

The refreezing pack ice. Blowing snow will soon obliterate visible traces of most of the former melt pools.

Second or multi-year ice showing a relatively smooth surface and developing a hummocky appearance.

Breaking fracturing ice in a lead. Without the dark of the water and new ice in the lead, this would be near whiteout conditions where sky and ice blend together and the horizon is indistinguishable in a continuous white landscape.

The Canadian Coast Guard icebreaker LOUIS S. ST. LAURENT seen close aboard in the fog. Not quite zero visibility conditions.

Sun seen through the clouds. Note waves in clouds. Hummocky appearance of ice would indicate second-year or possibly multi-year ice.

New ice formed over a polynya with ice ridges and mult-year ice in distance.

The Canadian Coast Guard icebreaker LOUIS S. ST. LAURENT presents a ghostly apparatus as seen over the pack ice and mist.

The Canadian Coast Guard icebreaker LOUIS S. ST. LAURENT seen in the distance as the CGC HEALY makes its way through a lead with nilas and frazil ice .

The Canadian Coast Guard icebreaker LOUIS S. ST. LAURENT seen over pack ice and leads from the CGC HEALY.

Second or multi-year pack-ice with ridges extending to the horizon.

Frost flowers on nilas ice with brash ice in the lower right corner.

Nilas ice at the edge of the pack ice. Frost flowers can be seen as white speckles on the new ice.

A beautiful clear night with the CCG LOUIS S. ST. LAURENT astern of the CGC HEALY as it crushes its way through second year or multi-year pack ice. Melt pools and channels have now completely refrozen.

Moon, pack ice and new ice in a polynya or perhaps at the edge of the pack ice. The LOUIS S. ST. LAURENT is seen in the distance.

A snow shower as seen over a hummocky ice landscape.

Sun seen through the clouds reflecting off grey ice.

The CGC HEALY proceeding through grease ice with some small floes in the area.

The LOUIS S. ST. LAURENT seen through fog in what appears to be first year pack ice.

Sun seen through the clouds over the jackstaff as the CGC HEALY proceeds through ice floes.

A squally day with sun occasionally breaking through the clouds. Ice floes cover the Beaufort Sea.

The CCG LOUIS S. ST. LAURENT seen nearly bow on entering a polynya.

A wall of fog obscures the view of first year ice floes.

Parallel melt pools and ice floes provide a geometry lesson in near parallel features.

Parallel cloud bands converge at the horizon over a landscape of ice floes, melt pools, and a polynya to the right.

A helicopter eye's view of melting ice with clouds overhead illuminated through a layer of higher yet clouds.

Looking astern to the LOUIS S. ST. LAURENT while traversing a lead between first year ice floes.

The CCG LOUIS S. ST. LAURENT seen nearly bow on entering a polynya.

Wake of the HEALY causing ripples to form in the nilas ice at the edge of the pack ice.

First year ice disintegrating into floes at the end of summer.

Sun, reflections off new ice, clouds, pack ice, and new ice forming at the edge of the pack ice.

An ice bow caused by sun shining through tiny ice crystals in the atmosphere.

Passing through ice floes with the sun astern.

Sun reflecting off open water and ice floes

Hummocky second-year or multi-year ice floes.

Sun reflecting off open water and ice floes

Sun, red sky, and an expanse of open water with small bits of brash ice in foreground.

Sun, red sky, and an expanse of open water.
