Add 2016 to the data set...

Happy New Year!

This being a blog about science in the field, not a ton happens on here when Frost is not actually 'in the arctic.' However, 2016 has been a year filled with happenings that are worth sharing (one of which I won't delve into is the recent election). 

#1 Paleoclimate Teacher Workshop: June 2016 in Phippsburg, ME

During the 2015 field season (see previous blog entries), a plan was hatched to further outreach within the Ingoya arctic-climate research project by running a teacher workshop and it turned out to be a great success! It ran immediately following the 4th International Sclerochronology Conference in Portland, ME (1st week in June) and was dedicated to sharing information on the paleoclimate sciences but more importantly actual field & lab techniques that could be employed in middle & high-school classrooms. Below I've included pictures from the 3-day event that will explain the content and activities covered. A big thanks to the Ingoya crew but also to Bates College, Laura Sewell, Thornton Academy for their help in making this happen!

Many of the teachers involved in the workshop were able to take home tree cookies for classroom use. With my tree collection now empty, I set to making another group of (7) identical tree cookies from a large white pine (thank you Matthew Frost, logger extraordinaire). The aim was to find an exemplar record sufficiently large enough for class data-sets but also one that had some variation within the record and could be tied to potential environmental forcers of tree growth over time in the instrumental record.

Author in the field, literally my brother's field in Strong, ME where we acquired all of the tree cookies for analysis. 
Lastly from the Teacher Workshop, I've included a link below to my guide for high school teachers (or any other interested parties not willing to hold me liable) to embed their own clams in epoxy. Great fun for the budding sclerochronologist:

#2 Blogger Personal Sharing Alert: 

Petersburg, AK
2016 saw 4 of my closest friends were married within 5 weeks of each other. That made for a rather joyous and busy time of which I had the honor of being best man, officiating one wedding, dragging my poor wife (8 months pregnant) to stay in a lean-to without heat for a fall weekend in Northern New Hampshire, and missing the first day of school to be at my oldest friend's wedding in Petersburg. Alaska. As you may have picked up from the previous sentence, my wife and I also welcomed our son (and soon-to-be field assistant), Clark, into the world on Oct. 23.

#3 Climate Change Editorial Alert: 

On the climate front, never has the subject of climate change or the implications of a warming world been more at the fore-front of our news. First realizing the enormity of the issue as a budding 18-year old scientist in 2001, I have long held climatological studies near and dear and am heartened by both the press the current situation is receiving and our strides in developing non-fossil-fuel energy alternatives. On the other hand, I have my worries that it has become so mainstream for many to outright deny an entire branch of science, the very observation, hypothesis, results, and discussion of it, and politicize it outright whenever the subject arises. I can tell you from experience, climate-scientists are not fat-cats passing on biased information to fill their pockets/gild their resumes and the best-funded grant proposal would be the one that legitimately runs counter to the current scientific consensus on our changing climate and the causes...with factually based evidence. Most climate scientists I know are not naturally political and their agendas usually consist of recovering mud/fossils from remote locations and "ooh-ing" and "ahhh-ing" over data sets, pictures, & landforms when they are forced back into their labs and on their computers. As I step off the soap box, I encourage all to read a diversity of information on our changing climate but more importantly go explore and see your own backyard as well as new and exiting places because it is hard to gauge what is happening outside when your major source of temperature change is a thermostat. 

A good place to start reading is the most recent Arctic Report Card by NOAA:

6/8: Wrapping up, packing up, and hopping the next fishing boat south...

The first question asked by a good friend and former colleague, John Hagerstrom of CVA, when I told him I would be heading up to Svalbard for 6 weeks in July of 2012 was 
"Why the heck would you want to do that?"

Having worked many summers in the Arctic since 2002, the question happens again and again, but always from Mainers (and maybe a couple of times from my Nebraskan inlaws). Maybe it's just that they're so happy it is finally spring and the mud has dried up, the daffodils are blooming and they've finally got their hands into the dirt and cow manure but I do certainly have to wonder where their memory is if they have no qualms with 6 months of the picture below, but shiver violently at the thought of 2 weeks in the one above...

My driveway this February
It is our last day here on Ingoya and the last bits of science have been wrapped up with a quick trip here and a small water sample there. Erlend will be picking us up at 0-dark-thiry tomorrow morning (if there was such a thing this time of the year) so we can make the trip across the sea to Havoysund where we will be catching the M/S Finnmarken Hurtigruten and setting sail for Tromso. Please do at some point check out the official Hurtigruten website with the link below:

The site has all of the ships' biographies/fast facts, interactive maps with them buzzing about the Norwegian coast, and everything you need to plan your next Scandinavian adventure (try a Kwikk Lunsch!). We should arrive in Tromso at approximately 11:30 pm Tuesday night and then if all goes well I will be on a plane for Oslo at 8:30 Wednesday morning. Good ole' Newark next, then D.C., then Portland...don't ask why I am going to the capitol first...on to business. 

Packing up camp is always bittersweet as it is nice to see how lush Maine is in June but also there bits of Norway that will be missed, like how walking by these sights are commonplace here at the Sjøhus:
Not even sure what to call this...but a fish and a baseball cap are involved. 

Salmon being smoked as pass by toward the stairs
But there will always be more stories to tell: Like how we got interviewed by Norwegian Public Broadcasting and photographed by a drone. I guess I forgot to mention this earlier; it all happened very quickly (and randomly) in about a 30 minutes from meeting our journalist friend (who happened to be driving by and has a weekend house here on the island). 

Allan K. sets out his drone...we run for cover. 
"And this is my neighbor's Malta berry patch..."
Or how you can even take culinary lessons on the Hurtigruten while steaming down coast: 

If you read closely, you'll see the product can be vacuumed on board!
I think these are the on board chefs...
...or maybe the captains or "Norway's Most Eligible Fisherman" calendar of 2015. 
...Or how the first morning in Tromso, I knocked on Al's hotel door to go down to breakfast and mistook him for a middle-aged Norwegian woman. My apologies to all middle-aged Norwegian women. 
After: Hey, its Dr. Wanamaker!

Alas, all good things must come to an end and I've got my lovely wife, 3 dogs, and 5 classes of students to see back home. It has been real Ingoya, I got to hike your tallest peak today (and I will post video if editing time allows), and thanks to all the readers who have put up with my stream of consciousness blog reporting as it is the only way to conserve at least 5 hours of sleep and be useful for more than my witty cyber reporting (strong like bull, smart like tractor).

In the words of Erlend, "We try!" and now, we go...

6/7: The Seagulls are mocking us...

The Seagulls are mocking us.
Our view from the boat in the open ocean for one last day of deep-water dredging. 
If it was easy, everyone would be doing it. Scratch that, they would enjoying 70-degree weather not 70-degree latitude. If it was easy, all the other wack-o's would be up here trying to get Arctic Islandica from the deep water to assemble long term chronologies of the arctic climate with yearly resolution...but they probably don't share the determination of Al/Maddie of Iowa State, the guile of Erlend the fisherman of Ingoy, or the reserves of Julia today toughing out a return to sea legs while keeping a smile the whole time. So accordingly, we wear the difficulty of our task and our meager returns from the water as a badge of courage and we like it that way. Bottom line, it is not easy to get the samples we are trying for but we keep trying....and are actually getting results.

Erlend's boat provides ideal working condition and looks really cool.
To the seagulls that are mocking us: it was a pretty standard day on Ingoya (our second to last), we worked a full day's shift on the seas (the ground is moving as I write this to prove it), got a handful of live clams from ~500 ft. depth, and even managed to catch a couple of fish during the 7-minute window from when the dredge is released to when Erlend exclaims "We try!" Good day and the sea provides, we abides...
The returns from a ~20 minute dredge at about 500 ft. depth. The area we are trying for is deep and devoid of stones but proving tough to fill the dredge. The bottom type is right for the clams but also seems to be littered with shell remnants and urchins. Every few dredge 'the graveyard' turns up live specimens. 
When done correctly, you can catch science and dinner in the same drift
Every live A. Islandica from the deep water is a cause for celebration.  These deep water clams will tell us information on previously unstudied parts of the the North Atlantic currents as well as how these organisms (at the extent of their habitable environment) compare to the shallow water specimens we can collect in abundance. 

The picture all of my friends from rural Maine have been waiting to, catching fish for dinner while we work is the least carbon-intensive form of sustenance. There is not much reason to buy frozen fish in Tromso when...

One more full day here on the island...

PM infantry update: The weather was conducive for a day of cleaning up yesterday's recon. mission w/ Mike, Julie, and Sam on the ground while we were out on the boat. They were able to survey the beach terrace elevations we sampled yesterday as a group and also collect more in-situ material for radiocarbon dating. In-situ means in-position and this important so that we can tie the radiocarbon ages of the shell materials to the formation of the landform. We avoid shells that find their way to sites through happenstance, such as piled by birds or dug up by anything other than us, and don't provide any valuable information on the specific of the organism's living environment.

6/6: Weather Fixed

Harbor on a Saturday Morning
The people of Ingoy are an incredible bunch. Tonight we were invited to a local gathering of everyone on the island (fairly certain everyone that can walk) to promote the 150th anniversary of their lighthouse happening next summer. Artists from Oslo have come in for the occasion and are planning a theater/dance performance based around the rugged landscape (not my just my words but the theme). Being clearly the only group at the event that did not live there, they were welcoming and curious as to our findings/success on the island and even asked if it was ok that they did the talking at the event in Norwegian. We said that would be fine. They also somehow managed to find an incredible mix of the Beach Boys, Cat Stevens, and CCR to melodically guide us through the social event. Good work...
Erlend's boat in town
The event capped off our afternoon of hitting the peats and sands to determine our last objectives on the island with two days of work left to complete. A nagging question for our geomorphic group has been how to put into context the stair-step-like raised beaches on the southern coast of the island. These beaches are remnant from past sea levels, marking the successive stand stills for beach formation as the crust rebounded out of being glacially depressed (sounds like a downer). 
Follow the ridges you can see somewhat parallel to the coastline inland...those are the stair-steps
In reality, they are the type of landscape feature that surficial geologists dream of (very sequential, easy to recognize in person and from aerial photos, just subtle enough that you can still drive people nuts by getting really excited about them). The only problem with them though has been the availability of dateable material (carbon, not romance) without bringing in heavy 'fern gully' destroying-type machinery. Today we were shown a way to get at the samples needed for radiocarbon dating by the rabbits: Rabbit holes. They are excellent little amateur archaeologists and in many locations have found habitat under the massive peat layers. Our systematic inventory of areas suitable for sampling consisted of starting at the first of the ridges, then following them until we found a hole. Q: Are there shells in the bottom of the hole from Petre Rabbitsan? A: Yes...try there. Next ridge. This is in reality a gross oversimplification but suitable for the purpose of finding shells under thick organic material forming for thousands of years. You ain't just digging...

I will let the pictures and captions tell the rest of the story because it is a beautiful night, the midnight sun will be out in 30 minutes, and I have to try and see if I can get FaceTime to wish my mother, Brenda, a very happy birthday. Please feel free to send warm birthday wishes to: Extra points for further distance from Farmington, ME. She'd think it was great! Night...

Shells are found quite quickly beneath the surface but be weary of areas that have already been dug by human hands.  Is that really a viking ship? Don't mind us, just passing through...
Much of the soil here under the peat is comprised of marine carbonates. Many different types of shells are present and in tact just as common as pebbles in Maine
