Mapping the early formation of the oceans

When I was a girl, we traveled to Puebla to visit my grandparents in a town near the Popocatépetl volcano. The fumaroles (smoke) scared me, so I studied the characteristics of the hills around me to find a safe place in case it blew up.


Big Pagoda Pools — Microbial Mysteries video update

This spectacular underwater volcano was just explored for the first time by scientists aboard the R/V Falkor. 2000 meters below the surface of the ocean, the “Big Pagoda” hydrothermal vent is massive: 30m tall and 23m wide.

The discovery of Riftia

Greetings from Guaymas basin! My name is Jessica Mitchell and I am in my fifth year of working on my PhD at Harvard University with Dr. Peter Girguis. I study the microbial symbiosis between Riftia pachyptila and its bacterial ‘symbiont’ Candidatus Endoriftia Persephone.


Microbial mysteries: Week 1 video

“I don’t know exactly what we are going to find, but we are going to learn something incredible… This is the type of place where you can actually find something new in terms of metabolic diversity!”

Gulf of California: Using radium isotopes to study hydrothermal flow dynamics

Hello everyone! My name is Charlotte Kollman and I am a graduate student in the Groundwater Discharge Measurement Facility at Coastal Carolina University. I am currently aboard the R/V Falkor in the Gulf of California with scientists from several different institutions, all with the shared goal of exploring the biological mysteries that abound here.

Underway: Linking microbial Communities and evnironmental

After a very long and unanticipated delay, we are underway and headed towards the Guaymas Basin, located in middle of the Gulf of California. The Gulf of California, one of the most intriguing places I have worked, is home to deeply interesting and fascinating seafloor habitats.

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: Slurp and Discover

The Remotely Operated Vehicle SuBastian is equipped with what we call a “slurp system.” It is a long flexible hose with a nozzle that can be used to suck up things from the seafloor into canisters on the ROV.

Costa Rican Deep Sea Connections: Deep-Sea Geobiology

As we hiked up the steep cliffs of Isla del Coco, through the dense forest of ironwood trees covered with bromeliads, I was struck by the similarities in the structure of these mountains, most of which are entirely underwater.
