Collecting Data from the Ice Shelf – sediments, oceanography, and ice thickness.

After nineteen days on the ice shelf we’re all happy to be back on board Oden, with access to saunas, showers, and the wonders of the galley.  In those nineteen days we drilled through the ice shelf at three sites, one near the grounding line where the glacier first goes afloat, with the other two… Read More Collecting Data from the Ice Shelf – sediments, oceanography, and ice thickness.

Boulder Sampling Alongside Petermann Glacier; camping logistics and lateral moraines

Before arriving to Petermann glacier, the Boulder Team looked at aerial photos of Washingtonland, located to the west of the glacier, to determine the best camping site for our three-week field study. We wanted to be close to a rich sampling area and somewhere relatively sheltered and flat to make for easy camping. While on… Read More Boulder Sampling Alongside Petermann Glacier; camping logistics and lateral moraines

The Life-Cycle of a Sediment Core aboard the I/B Oden

A few days ago my husband Paul and I celebrated our second wedding anniversary by splitting cores collected from Nares Strait and Petermann Fjord.  In spite of the high-velocity mud spatter, this ‘celebration’ was fairly sentimental for us: we got to know each other splitting cores on the exact same circular saw frame, nearly nine… Read More The Life-Cycle of a Sediment Core aboard the I/B Oden

Mapping the Seafloor: how sound revolutionized our understanding of the bottom of the ocean

People have been mapping the seafloor for ages.  A statue found in an Egyptian tomb from 2000 BC shows a seaman using a weighted line to measure the depth of the water ahead of his vessel.  For the next almost 4000 years, seafarers used variations of the same technique – dropping a weighted “lead-line” to… Read More Mapping the Seafloor: how sound revolutionized our understanding of the bottom of the ocean
