A Tale of Two Labs

Young Lab: The Young Lab (right picture) from the University of Oregon has had a busy first day aboard the R/V Atlantis! After being briefed about the day-to-day operations with DSV (Deep Submergence Vehicle) Alvin, we all introduced ourselves to the WWU crew and decided on a dive schedule for the cruise. The rest of the day was spent prepping the lab space! Equipment for various experiments had to be assembled (more to follow soon!), chemicals prepared, and gear strapped down. This last step is most important in case the vessel encounters rough seas. With all set and ready to go, the Young Lab eagerly awaits the voyage ahead.

Arellano Lab: A late night for the Larval Lab (left picture) after a day of travel, but we are excited to be on board R/V Atlantis! Lugging around seven *very* large tubs of lab equipment and luggage through the SeaTac airport security was quite a feat, but everything made it to Gulfport in one piece (as did we!) Today mostly entailed organizing the lab and exploring our new shipboard home. We all eagerly awaited to see the results of a lottery draw to know who would get an Alvin dive during the cruise—it looks like three WWU students will get to descend into the deep sea!!! Departure at 8:00 a.m. tomorrow will bring a nice relaxing day at sea!

Authors’ Highlights:

Lauren Rice is a PhD student at the University of Oregon – “It was a long and hectic day setting up the lab but seeing the faces of the undergraduate helpers as they received the dive assignments was absolutely priceless. 😊”

Laura Anthony is a senior at Western Washington University- “Hopping inside of the larger-than-expected Alvin was a lifelong dream come true!”

Dispersal of deep-sea larvae!

It’s time to bring Alvin out of its bay as we start our new project!

Ever since deep-sea hydrothermal vents and methane seeps were first discovered in the deep ocean more than 40 years ago, scientists have wondered how these isolated communities, fully dependent on underwater “islands” of toxic chemicals, are first colonized by organisms, and how the populations of these specialized animals are exchanged and maintained. These fundamental processes depend on the transport of babies (larvae) by the ocean currents, yet because the larvae are microscopic and diluted in the vastness of the ocean, it is very difficult to determine where and how they drift……until now!

The Larval Lab and our friends at the University of Oregon and North Carolina State University are embarking on a 3 year project to figure out where the babies of deep-sea cold-seep animals go. Our project uses a combination of underwater robots to collect larvae in the field, rearing and observing the larvae of deep-sea animals in the lab, and mathematical models to show how biology interacts with ocean currents to predict which methane seeps will be colonized by larvae originating at different depths.
