Seeking the Seeps
The unusually bright Oregon sun beams down on me as I watch the soaring Astoria bridge recede into the background. The R/V Falkor has just pushed back from the dock and we’re steaming into the great Columbia River. Looking ahead, I can see twin points of land, framing the mouth of the Columbia like a giant crab claw.

Seeking Space Rocks: The search continues
The seaborne portion of our expedition has ended, but the land-based search begins. In the laboratory, all the samples are examined with fresh eyes, using instruments that enable Dr. Marc Fries to “see” potential meteorites at a much finer scale.

According to plan
After picking up the science team in Astoria, we headed back out to sea! This time we headed northward to the Olympic Coast National Marine Sanctuary off the coast of Washington State. The aim of this leg is to try to locate and recover fragments of a meteor strike recorded off the coast.

Improving the odds
Overnight, the ‘star sieve’ returned several hundred grams of rocky material with characteristics similar to what we are looking for in meteorites – black-colored rocks with a smooth exterior surface. But when ALL of the samples from multiple sites look that way, you have either hit the jackpot or something else is going on.

Seafloor mud is a mucknificent thing. The soft surface of well-sorted, very fine silt and mud provides a wonderful foundation for benthic organisms, but also allows all the larger, coarser, and heavier rocks – including the meteorites we seek – to bury themselves within.

The Hunt for the Quinault meteorite begins
The sea is pitching 8 foot swells at the R/V Falkor as the “Seeking Space Rocks” team transits to the first dive site in Olympic Coast National Marine Sanctuary. We have three days to look for meteorites on the seafloor, the second time this has ever been attempted.
