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.

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.

Mucknificence

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.

Costa Rican Deep Sea Connections Videos — Week 3 Update, Species Discoveries & Methodologies

“Isla Del Coco is really a special place. Now that we have gotten a look at some of the deeper parts and discovered some of the really spectacular communities of the deep sea… we know we’ve found new species: new species of coral, new species of shrimp, new species of worms – a LOT of new species.”

Costa Rican Deep Sea Connections: No Bone is Safe

Some of the creatures the experts have been observing seem otherworldly, even eerie. It is not unlikely that the brilliant H.R. Giger got his inspiration for the extraterrestrial monster in 1979’s Alien from the planktonic crustacean Phronima.

New Approaches to Autonomous Exploration at the Costa Rican Shelf Break: Wrap Up Video

“We are building technologies that allow us to do more with less. And if you think about the history of oceanography would have been unthinkable even 30 years ago. By pushing forward on the technology we are able to greatly expand our ability to observe our world.”

A Numbers Game

The oceans are big. The universe is even bigger. A needle in a haystack does not begin to describe the difficulty of finding what you are looking for on the Earth’s seafloor, much less below the icy cover of a moon orbiting Jupiter 588 million kilometers away!

Advancing Autonomy at the Costa Rican Shelf Break — Week 1 Video

Researchers are off the coast of Costa Rica, testing robots by integrating sensors, software, and mechanics to create underwater vehicles that can travel through unknown and potentially hazardous subsea regions. These types of vehicles, once able to make decisions without input from humans, will help us understand the oceans of Earth, as well as other planets.

Interdisciplinary Investigation of a New Hydrothermal Vent Field: First impressions and old friends

First impressions do not always turn out to be right, but they stick with you. I remember my first impression of the Auka vent field when, using the Monterey Bay Aquarium Research Institute (MBARI) submersible Doc Ricketts, we discovered this hydrothermal field on April 12, 2015.
