Coast Guard icebreaker stops in San Diego before Arctic mission (this past Sunday)
Quote
A head of its annual summer research deployment to the Arctic, U.S. Coast Guard Cutter Healy is stopping over in San Diego to pick up supplies [from the Scripps Institution of Oceanography] and give the public a window inside the ice-breaking operations of the branch’s largest ship.
...
This year, Healy’s missions revolve around studying climate change, examining how sound spreads under water and studying ocean currents. Missions are typically funded by a science institution with 2018’s operations financed by the National Oceanic and Atmospheric Administration, the Office of Naval Research and the National Science Foundation.
...
Healy depart[ed] San Diego on Tuesday and will return to Seattle for a two-week break before a five-month deployment to the Arctic.

The Healy is a little north of San Francisco right now.

A research team led by Woods Hole Oceanographic Institution (WHOI) found the fingerprint of a massive flood of fresh water in the western Arctic, thought to be the cause of an ancient cold snap that began around 13,000 years ago.

https://phys.org/news/2018-07-fingerprint-ancient-abrupt-climate-arctic.html

Next steps in future research, Keigwin says, will be for scientists to answer remaining questions about the quantity of fresh water delivered to the North Atlantic preceding the Younger Dryas event and over how long of a period of time.

"Events like this are really important, and we have to understand them better," adds Keigwin. "In the long run, I think the findings from this paper will stimulate more research on how much fresh water is really necessary to cause a change in the system and weakening of the AMOC. It certainly calls further attention to the warming we're seeing in the Arctic today, and the accelerated melting of Greenland ice."

Earlier this year, a paper by researchers at the University College London and WHOI found evidence that the AMOC hasn't been running at peak strength since the mid-1800s and is currently at its weakest point in the past 1,600 years. Continued weakening could disrupt weather patterns from the U.S. and Europe to the African Sahel.
Science is a thought process, technology will change reality.

Healy is headed north (map)

Coast Guard Icebreaker Healy Deploying to Arctic Ocean
Quote
SEATTLE — The Coast Guard Cutter Healy is scheduled to depart July 24 for a four-month deployment to the Arctic Ocean to carry out multiple scientific research missions, the 13th Coast Guard District announced in a release.

Healy will provide presence and access to the Arctic while conducting three major science research missions. In partnership with the National Science Foundation, National Oceanic and Atmospheric Administration (NOAA) and the Office of Naval Research, scientists will conduct physical and biological oceanographic research in the Arctic Ocean.

Healy’s first mission is a NOAA-sponsored mission to increase understanding of biological processes along Alaska’s Continental Shelf. This mission comprises three mission subsets: Distributed Biological Observatory, Northern Chukchi Integrated Study, and the Ecosystems and Fisheries-Oceanography Coordinated Investigations.

Just left Kodiak Island.  Presumably headed around the Alaska Peninsula on the way to the Arctic.

The Healy is going back and forth, back and forth.  Alas, no ice in sight.  But there is a UFO - Unidentified (by me) Flickering (period: 1 day - lasts a few hrs) Optic (or light) - probably a reflection of equipment on the bridge.

(Remember: multiple Healy links at the top of this page.) [Note to self: post #1955: a very good year!]

WASHINGTON — The U.S. Senate passed its annual defense authorization bill Wednesday, ... and directing the Navy to procure a new Arctic icebreaker.
...

The bill would procure a single icebreaker via the Navy, but it would also authorize the Coast Guard to "enter into one or more contracts for the procurement of up to five additional polar-class icebreaker vessels," according to the conference report.

How to procure an icebreaker has been more controversial than whether to do it. The Coast Guard has not bought a new icebreaker since the early 1970s, and the cost of building one is roughly as much as the Coast Guard's entire annual shipbuilding budget — $1 billion. That makes funding difficult to get through Congress.

Last year, [Alaska Sen. Dan] Sullivan included a provision allowing purchase of six polar-class heavy icebreakers in the FY18 authorization bill "and it got stripped out of the conference," he said.

Currently, the U.S. has just two polar icebreakers in working order, one heavy-duty ship and one medium-duty research vessel. Reports indicate Russia has more than 40 icebreakers, and more in the works.
Anchorage Daily News

I think icebreaker funding has been stripped out of bills during Senate-House conferences many times over the years.  Will this year be different?

Healy has found some sea ice!

In not too many years, I can imagine the Healy retrieving such a piece of ice -- so it can be put in a museum.

It looks cold now... (image below)
And from the ship track:

Oceanographic research ship USCGC Healy (USA)
...
Last reported at 2018-Oct-29 00:00 UTC. Time now 2018-Nov-02 19:05 UTC.
Position  N 66°48' W 168°24'.

Wind from 280 at 8 knots
Barometer 1013.6 mb
 Air temperature -1.2 ° C
 Dewpoint -3.7 ° C

Odd that the last info is from October 29, although the cam is current.  Would the water have been warmer where the ship was 4 days ago (3º further south, per image lat./long/)?

Some of the current crew’s 'positions' include:  CTD watchstander, Collaborating scientist, Collaborating student, Post-doc/Microstructure, Student/Chlorophyll, Student/Radium, Seabird Observer. (from here)  All of their nationalities are "TBD".  Hmmmmm

Healy today - near the edge of the continuous floe, it seems.  Is that some pancake ice amongst broken floe bits?

So that list is just a submitted questionnaire from the Chief Scientist of that particular leg- so it's actually a list of embarked Science Party members, who aren't permanent crew.   They join the ship for their research trip and leave afterward.   The active duty USCG crew stay on all season (and just got back last Friday, as it happens).     

The group from this linked questionnaire was the HLY1803 (third expedition for Healy's Arctic West Summer 2018 mission season), which was the second trip of the year on Healy for Bob Pickart, who is one of Healy's most frequent customers (he was also the ChiSci for HLY1801, back in August).     He's a physical oceanographer from Woods Hole Oceanographic Institute.     

The other trip this year was HLY1802, SODA (Stratified Ocean Dynamics in the Arctic), which was a component of a multiyear Arctic oceanography research program funded by the Office of Naval Research and run by the University of Washington.

Thanks, amstenseth,
Here is the last image with some ice: FROM 2018-11-27.  The lat-long on the picture [57.8333; -133.1167] puts it in [near???!!!  :o] Tracy Arm Fjord.

Healy is now 'safely' back in harbor.

Yep, Healy sailed the Tracey arm on her way back home as part of the TIGER cruise, which is an event where family & friends of the crew are invited aboard to get a taste of shipboard life.   

This year a wedding was held aboard, officiated by the Captain.

Some photos (of the fjord, not the wedding):
