NASA: Extreme shrimp may hold clues to alien life

Originally posted on fox13now.com:
Shrimp crawling around rock chimneys spewing hot water deep in the Caribbean Sea may hold clues to the kinds of life that can thrive in extreme environments on other planets, NASA says. The shrimp are called Rimicaris hybisae (no, we can’t pronounce it either). They live in clumps on…

Extreme Shrimp May Hold Clues to Alien Life

Shrimp called Rimicaris hybisae at deep hydrothermal vents in the Caribbean seem to have different dietary habits depending on the proximity of other shrimp. Those who live in dense clusters like this one live off bacteria primarily, but in areas where the shrimp are distributed more sparsely, the shrimp are…

Santa Cruz

Earlier this month I gave a seminar at the University of California Santa Cruz, Department of Earth & Planetary Sciences, in their Whole Earth Seminar series. A very enjoyable experience. Their campus is a redwood forest, and the people were very welcoming and interested. Though, I maybe should have talked about shells instead of hydrothermal […]

The world’s deepest hydrothermal vents: An analog for Europa?

Two weeks ago a group of students from the University of Southern California visited JPL. They all did a summer program in ocean sciences. I was one of the people telling them what “real” ocean scientists do at JPL.

Welcome to my website. I am a researcher in biogeochemistry, most recently at NASA Jet Propulsion Laboratory in Pasadena, California. Here you can find information about my publications, travels, and other science related activities.

My most recent research was on submarine hydrothermal vent geochemistry and its application to life detection on Europa and understanding the origin of life on Earth. Past projects included the environmental significance of earthworm secreted calcite granules at the University of Reading (UK), and stable-isotope work and proxy development on freshwater and marine bivalves at VU University Amsterdam and the Vrije Universiteit Brussels (Belgium).

I am originally from the Netherlands and obtained my MSc degree at Utrecht University and PhD at VU University Amsterdam.

I love classical (especially early) music and sang the in various choirs, such as Reading Bach Choir, the Capella Sanctorum Michaelis et GudulaePasadena Master Chorale, and at the moment Brabants Kamerkoor. I like hiking and running and it makes me very happy when we can skate on natural ice in the Netherlands. When on holidays I like to SCUBA dive or do amateur astronomy.
