Thanks, Tor, I had overlooked that one is in decimal and the other in minutes.
I now think that the camera timestamp is automatic and therefore the more reliable (also more recent)
looking at the data on the ship track site, there is what looks like a decimal point slip in temperatures  (44 deg water temp at 00:00 on the 11th ?) so these are probably entered by someone by hand and therefore more likely out of date.
but:
 pos given at 13:00 on 2015/07/11:  71.40 / 160.60  on sailwx
is a close if not exact match to photo 20150711-1301 71.463 / 160.586
what made me question  the times was originally the observation that water temperatures were lower with little ice at 13:00 than at 18:00 with more ice seen. With your help I now am convinced that this is genuine, The large floes seen at 18:00 can probably last for a while in water of 4.5deg.

That's the ice edge not far from Point Barrow. Do they measure (and share) ice thickness as they encounter it?

I didn't find any scientific data made available, but …
Some shipboard information is available from the Healy AWS15 Cruse Updates page

From the June 29, 2015 post:
… Returning readers will recall the historic events of AWS 14 involved the rescue of the sailing vessel Altan Girl from pack ice 40 miles north of Barrow, AK. HEALY hopes to make history once again this summer as we become the first unaccompanied U. S. surface vessel to transit to the North Pole. Reaching the North Pole is scheduled to happen during our second mission of the summer. The second summer mission, known as Geotraces, is sponsored by the National Science Foundation and will focus on the chemistry of Arctic waters.

We will have more on both of these missions in the coming weeks. ...


There are multiple references to "follow our track map".  This is different from the position & weather site.  I'll add it to post at the top of this page.

recent Healy news: http://www.sldinfo.com/coast-guard-cutter-healy-arctic-cruise-2015/ [Go here to see the pictures.]
07/16/2015:
  • (First image) The Coast Guard Cutter Healy breaks through ice in the Arctic circle, July 14, 2015. This image was taken by an Aerostat, a self-contained, compact platform that can deploy multiple sensor payloads and other devices into the air.
  • In the second photo, a conductivity temperature depth monitor is lowered into the Arctic Ocean from the Coast Guard Cutter Healy July 10, 2015. The CTD monitor will test the water for oxygen levels and salinity.
  • In the third photo, a small-boat crew from the Coast Guard Cutter Healy works with scientists to place a device called a wave rider into Arctic waters for testing, July 11, 2015. The Healy is conducting operations in the Arctic with the Coast Guard Research and Development Center and scientists from various other agencies.
  • In the fourth photo, National Oceanographic and Atmospheric Administration scientist Kevin Vollbrecht launches a Puma unmanned aerial vehicle from the bow of the Coast Guard Cutter Healy July 11, 2015. The Puma is being tested for flight and search and rescue capabilities.
  • In the final photo, Coast Guard Cutter Healy crewmembers move a 1,000 pound buoy into place for deployment in the Arctic, July 10, 2015. The buoy also has a clump anchor, which will keep it in place until it is recovered.
(Note: some quote formatting adjusted.)

The article includes:
The Coast Guard has told Congress it needs at least three medium and three heavy icebreakers. Global warming means more activity in the Arctic, and more civilian vessels are venturing north into harm’s way.

... The U.S. is also in the process of mapping the seafloor north of Alaska, with an eye to claiming more of the continental shelf, and the resources it may contain.

The increased activity means the U.S. could face more challenges to its interests in the polar latitudes…..

Healy has just left the Arctic.  Now to wait for early August when the exciting (for me) mission starts, as they intend to sail to the North Pole - we will see lots of sea ice!  Read above (especially the Jan 22, March 30 and July 12 posts) for some details and links.

From HEALY's July 17 Public Affairs Officer's post:
Today, we transited to the Arctic Technology Evaluation (ATE) 2015’s highest Northern point, approximate latitude 73 43.5 N. Unfortunately, the ice coverage was marginal; so, we were unable to conduct off ice Puma flights, ice characterization, or ice liberty on this cruise. We are now transiting South, returning to Nome. Some of our science and technology evaluations continue, and the teams and crew continue to interact.

Over 50 Arctic Researchers on Coast Guard Cutter Healy Preparing North Pole Voyage


A map provided by Geotraces of their route to the North Pole this summer. Image: Geotraces.

Excerpts from article:
[The Geotraces project] — part of an international effort to study the chemistry of Arctic waters.
...
Part of the plan is that we’ll have a cross-over station with the Europeans and a cross-over station with the Canadians. And we will compare our measurements with their measurements to sort of quality control that our measurements are indeed what we think,” said Ana Aguilar-Islas, an assistant professor of chemical oceanography at the University of Alaska-Fairbanks.

Those “measurements” include things like nutrient levels, as well as toxins like mercury and lead. Some will be compared to past surveys, while others will be made for the first time.
...
Another reason for the trip north: observing how waters from different parts of the planet mix in the Arctic. That includes warmer water passing through the Bering Strait from the Pacific, but also “heavy water” from the Atlantic.

A team of 50 scientists, students, and technicians will embark on the U.S. Arctic GEOTRACES expedition this year, 9 August - 15 October 2015, aboard the U.S. Coast Guard Cutter Healy.
See above for more.

From the Alaska Dispatch News
No one aboard is supposed to wear red out of respect for a tradition that only allows the color to be worn when the vessel is sailing above the Arctic Circle. (Sailors, scientists and journalists who have done so are initiated into this privileged group, the Order of the Blue Nose, with a secret ceremony.)

Looks like the Canadian portion of GEOTRACES on the Amundsen is back in action again (http://blogs.ubc.ca/geotraces2015/ ) after the diversion to break ice in Hudson Bay.  But like all expeditions, they are experiencing challenges, at the moment from equipment and not the weather or ice.

Where the Healy is, the air and water temperature today (so far) has been:
Air temperature 0.6 to 2.2 ° C 
Water temperature -0.6 to -0.8 ° C 

Visibility: 0.3 (foggy) to greater than 5.4 NM.  Skies are overcast (per the Healy bridge cam).

It appears the Healy has been in open water to ~50% ice today, and all the ice appears thin and to be covered with a light fairly fresh snow.

Of interest, perhaps, from Shell’s Icebreaker Heads North For Oil; The Coast Guard’s, For Science (Unalaska Community Broadcasting - August 07 2015):
...
On Thursday afternoon, members of the scientific team were building a bubble of plastic sheets inside the Healy.

“The ship is kind of a dirty place,” geochemist Phoebe Lam from the University of California, Santa Cruz, said. “It’s rusty. There’s dust everywhere, and in order to do a lot of the measurements that we’re doing on this cruise, we need to create a clean environment.”

Inside the filtered air of that pressurized bubble, scientists will try to get uncontaminated measurements of dozens of different elements, compounds and isotopes, some of them common, some of them measured in parts per billion.

Most of the ice pictures from the Healy until today have shown ice very low in the water, with the elevation of the ice barely above the waterline. Until today, when some ice with some ridges has appeared on the webcam.

Wind from 060 at 15 knots
Barometer 1018.7 mb
Air temperature -2.2 ° C

Water temperature -1.7 ° C

100% ASI concentration?

Do I recall right that bottom melting continues until the water temperature is less than about -1.8°?  I don't think these frozen melt ponds are freezing solid very fast (at -2.2°).

For 13 hours, the Healy has been still in the water.  It appears to be sitting in a lead.  I’m going to guess they are doing some research there with convenient access to open water.

They haven’t updated temperature (etc.) information since Aug-29 at 15:00 UTC, but the webcam suggests they are now at Long: -179º 42’ Lat: 87º 33’
Thirteen hours ago they were at -179º 48’ & 87º 30’ with the exact same ice just in front.  (See reply #100 [above] for links to webcam, etc.)  Does this show the ice (and ship) are drifting?

(No new environmental data)

As there are 111.699 kilometers per degree (at the pole), Healy is about 117 km from the North Pole.  Will all the fog, they won't see Santa's workshop unless Rudolf is on shift.  :P

It's as Clear as Mud Sept. 6 blog post from the Healy

...
The sediment in this region is soft, so the plan was to drop a small general-purpose device called a Mono-corer over the side of the ship with a few small weights on top to help drive the core tube in straight. The corer would hang below the bottom of the rosette of water samplers, far enough below that the rosette would remain ‘mud-free’ but still able to collect near bottom water samples. The mud in the mono-corer would be held in place by a spring-loaded door that snapped closed once the mud was inside and the tube began its return trip to the ship. All sounded good.

Although the plan was good, things don’t always go perfectly. Making sure the corer actually penetrated the sediment without tipping over or over-penetrating and compressing the top sediments proved challenging, as did ensuring the sample made it back to the ship intact. After several attempts a special ‘cone-of-silence’ (any Get Smart fans out there?) was rigged up by the two Lamonters, Tim and Marty Fleischer, to avoid interference with the communications that were connecting with the rosette altimeter, controlling the lowering of the device. The cone was installed and the speed of the core lowering was slowed. Success! ‘Houston we have mud!’

Now to unpack its secrets.



Core on its way up to the Healy. Note the core-of-silence rigged by Tim Kenna and Marty Fleicher to stop any interference with the rosette altimeter used to lower the device. (Photo Bill Schmoker)

Look carefully and you can see the candy-striped  "North Pole".  Santa, apparently, showed up for pictures.

Heading south, apparently along the route taken north.  Now 70 km south of the NP.

The scientists aboard Healy tried to gather ice measurements along the journey but were stymied by finding slush instead of solid ice until they were within 100 miles of the North Pole, they said in a Coast Guard press release.

"It’s hard to believe how slushy the ice has been so close to the pole; this was the first area we were confident enough in the ice conditions to allow on-ice science experiments," they wrote. "Despite being thick, the ice we encountered further south was simply too soft and unstable to safely put individuals on."

Are we watching slushy ice ice-over during a ~14 hour period?
(Look at the 'pond' at about 1 to 2 o'clock from the pointy thing on the ship's prow [straight ahead would be 12 o'clock; straight to the right would be 3 o'clock])

The Healy has been in the same location since 20015-09-10 1 am GMT, but earlier ice cover isn't so clear.  (The apparent difference between 1 am and 2 am images are most striking.)

The Healy has been stationary for 8 hours at about 85º N.  The snow-covered ice makes me think of winter.  (There is not updated temperature information.)

Note there is a person on deck.

Most images recently are of snow covered ice.  Some have ice without snow cover like this one from 2 pm GMT:

Is that some open water on the right?
