Today’s plan is to extend the sampling to include a wider region of the water exchange between Alison (Nanatakavsaup), the surrounding ocean and the connection to Hayes glacier. At the Village Meeting we had queried the local fisherman about the iceberg exit pathways for both Alison and Hayes to confirm or correct information we have gleaned from satellite imagery.

When North Itself Wanders

Earth's magnetic field lines are almost vertical near the poles. The dancing lights of the aurora borealis are the result of interactions Earth's magnetic field, atmosphere, and energetic particles from the sun. Image credit: NASA's Goddard Space Flight Center.

I love thinking about why my compass points north.
The deep, molten-metal motions, rising
And falling … gargantuan currents of iron
Conceiving vast magnetic fields, revealed
In my hand, by a tiny, quivering red needle.

Once again this year the Earth Institute is a beneficiary of Climate Ride, the national bike ride to raise charitable donations for and awareness about sustainability, active transportation, and environmental causes. Participants can select the Earth Institute as a grant recipient when riding in any 2014 Climate Ride event, and anyone can support one or more riders with a donation toward their personal fundraising goals for the event.

The science goal for today is to complete 8 CTD casts. We load into our vessel, a Poca 500GR. We have discussed a 6 to 8 hour window of boat time with Gabriel the captain and Magnus our navigator and stocked up on 40 liters of benzene.

It seems that many of the local fishermen have gone to hunt Narwal further north but there are several good prospects for boats that Søren will scout further as several of the fishermen are sleeping as the fishing is better right now at night. With 24 hours of daylight day or night fishing doesn’t really seem to matter.

I am a wild carbon atom,
To others I’ve sometimes been bound,
Not locked in some hard, rocky stratum,
I’m telling you: I get around!

At the small airport a smiling woman approaches us asking our plans in one word “Kullorsuaq?” We smile and nod and she grins broadly motioning that she and her daughter are going there too – it is their home she manages to convey.

Metals galore in deep Earth,
But at the sea surface, a dearth.
Iron is key
For greening the sea …
To planktic cells, gold has less worth.
