Lab Work

Someone holds a small thin metal spatula with a small clump of dirt balanced on the end. A small amount of dirt is piled on a white plastic tray. The person's arm is stretched across a long core sample with a ruler next to it. Everything is on a dull, mint-green table top in the ACGL lab.
Sometimes we collect sediment samples from the core to give them a closer examination.
Someone stands in front of the grain measuring machine. They have a hollow golden cylinder on top of one of the machine's holes. They are holding a glass cylinder and a thin metal spatula. Behind them are two people on computers. They are inside the ACGL lab
Part of grain analysis is measuring different aspects of sediment grains, like size, shape, roughness.
Someone sits in front of a microscope, there is a clear tray with brightly lit sediment. The person is poking at the sediment with a thin metal spatula. They are sitting in the ACGL lab. In the background, someone isd sitting at a computer with three monitors.
Closely examining the sediment can give us ideas of what kind of minerals are in a sample.
Someone is holding a glass tube and a thin metal spatula. The glass tube is pouring liquid into a hollow golden cylinder. The cylinder is resting on one of the holes of the grain analysis machine.
Sometimes we use water to help loosen stuck particles.
Josh Barna stands in front of a muffle furnace. While wearing a thick, tan glove, he is moving a tray of crucibles. Behind him is a large geologic map of Alaska and a white board with some red lettering on it. He is in the ACGL lab.
Josh focuses to make sure he doesn’t burn down the lab again.
Three people stand in front of a table writing on clipboards. On the table is half of a core sample, a ruler and colored pencils. They are inside the ACGL lab. Behind them someone is looking at a large map of Alaska.
These students are taking diligent notes on the core sample laid before them.
Two people sit in front of a computer with two monitors. One monitor shows a graph with prominent black zig-zag lines and the other shows an aerial image. There is a small 3D model of ice wedges on the table. They are inside the ACGL lab.
Some ACGL members looking over graphs and aerial imaging.
Chris Maio is showing two students pages in a binder. Behind them two people are working on desktop computers. There is a map of the Arctic Ocean on the wall. They are in the ACGL lab.
Chris looking over some papers with a couple of his students.
Someone holds a mortar and pestle, there is brown liquid pooled in the mortar. It is sat on a metal sheet with patterned holes.
Sometimes we need to break down the sediments we collect to get a thorough look at all the particles.
Someone holds a hollow golden cylinder, at its base is some wet sediment spread out around tthe bottom. Under the cylinder is a metal sheet with patterned holes.
Getting a sample wet can help prevent clumping that could potentially hide interesting particles.
Someone stands next to a table with two halves of a sediment core. They are holding a scraper. There is a notebook resting on the side of the table. They are inside of a lab room.
Preparing sediment core for observation.
24 crucibles are layed out on a tray. There are clumps of dried dirt in them ranging from mahogany to light grey. The tray is resting on a metal sheet with patterned holes.
Heating samples in the muffle furnace can help determine how much of a sample contained carbon materials.
Someone sits in front of a microscope, peering into the eye pieces. There is something resting on the microscope's observation plate. They are in a lab room.
