This image was formed from acoustic backscatter data, one of three types of data collected by <em>Healy’s</em> multibeam echosounder, described below. The width of the swath is approximately 180 m.

Swaths of multibeam bathymetric data compiled on the ship’s Map Server. The swath collected during this mission trends east-southeast and has a dark line (the ship’s track) down the middle. The other data swaths were collected during earlier missions. The data are color-coded; in this view, orange tones indicate shallower water and green tones, deeper water. Note how the swaths widen with increasing depth. One of the swaths trending north-northeast in this view widens from about 1.5 km at 500-m water depth to about 6 km at 1,500-m water depth.

By the end of our first sampling day (actually by about 6 a.m. the next morning), he was batting 1000, having recovered core samples of the seafloor on three out of three tries: a gravity core followed by two piston cores.

(This seismic section does not run exactly through our sites, but through similar structures nearby.) The first two cores were collected atop a diapiric structure, where the layers of sediment have domed upward and formed a small hill on the seafloor.

The gravity corer relies on a weight at the top to drive the barrel into the sediment. In this photo, the weight, with a 10-ft barrel attached, is cradled in the blue “bucket,” which has been moved to the end of a specially built track. The bucket will be rotated 90° so that the core barrel points straight down, then the corer will be winched out of the bucket, into the water, and down to the seafloor. Standing by (right to left) are Pete, Jenny, and Coast Guard Marine Science Technician MST3 Marshal Chaidez.

Jenny holds a clean core catcher. This device attaches to the bottom of the core barrel with its metal teeth pointing upward. The teeth are pushed open by sediment entering the core barrel as it penetrates the seafloor. When the core barrel is pulled back out, the sediment inside the barrel presses the teeth down and together, so they hold the sediment in place.

The piston corer, which hit bottom at about 2,550-m water depth, came back with gas hydrate in the core cutter at the bottom of the core barrel. Gas hydrate looks like water ice but is actually made up of water cages that enclose gas molecules, usually methane. Gas hydrate is stable at relatively low temperatures and moderate pressures like those beneath the seafloor at the coring site.

We’ve been breaking ice ahead of the Canadian Coast Guard Ship <em>Louis S. St-Laurent </em>(<em>Louis</em>) since Friday morning to give her a clear path for towing her seismic-reflection gear, but we didn’t get a good look at her until today. Here she is in the early afternoon, emerging from the thinning fog.

The sun comes out just after <em>Healy</em> has made a turn onto a new trackline. As <em>Louis</em> turns to follow us, we get a good view of her port side. Just forward of the white stripe, you can see white bubbles foaming along <em>Louis’s</em> hull.

I took this photo shortly after 1300 hrs on August 14. The sun was relatively high in the sky, and so I could fit the whole bow in one frame. You can see the faint colors of the rainbow, with red on the outside and indigo on the inside.

A closeup view of Mark’s cups, with full-size cup on the right for scale. Although the lefthand cup went nearly 4 times as deep as the cup in the center, it did not shrink 4 times as much. We speculate that at a certain depth, all the air has been pressed out of the Styrofoam and no further shrinking takes place as the cup keeps going down. (We are too far north to access the Internet to check on this hypothesis!).

Louis is stuck on an ice floe beneath her port bow. When ice-breaking, Louis pushes her bow up onto the ice and then crushes down through it. The bubbles from her bubbler system (visible along the hull forward of the white stripe) help move the broken pieces away from the ship. This time, Louis rode up on a tough ice floe that did not break.

As the rosette ascends, an operator sends signals down the winch wire (an armored electrical cable) to close the bottles at selected depths, thus collecting water samples from throughout the water column.
