Afshin's Birthday


September 22, 2014

Happy birthday Afshin! A member of the science team, Afshin from Oklahoma State University, celebrated a birthday on the ship. Our wonderful cook Mike baked a cake especially for him. Yum!

sargassum seaweed

September 20, 2014


It’s been a long time since I’ve seen sargassum seaweed.  The brilliant blue Atlantic Ocean has such a different feel, smell, and color than that of the Pacific.  Sailing over the dark blue long-period waves and working among humpbacks, kelp patties, and Japanese tsunami debris is my typical science cruise.  It’s good to be back east and to be reminded of the profound, yet subtle differences of these two great oceans. -Ernie Aaron

OBS Recovery


September 19, 2014

At about 01:42 the night shift had successfully started a burn on a WHOI OBS located at the start of line 2. A burn means that the science crew was able to communicate with the device and send a signal telling it to burn through the wire holding the buoyant OBS to a metal weight attach to its bottom. The water depth in this area is around 5200 m, and it took about an hour and half for the OBS to rise to the surface once detached from the weight. The team located the OBS using a radio signal and visual contact (light and flag). With the OBS spotted, the Chief mate Shanna was able to maneuver the boat alongside the OBS, so that the science crew could snag it out of the water and bring it aboard. Since then we have recovered six OBS from both the WHOI and Scripps science crew. The seas have picked up a bit, but we are continuing to move westward along line 2 collecting the devices. From here we will prepare the OBS for redeployment along line 4.

The last OBS of line 2

September 19, 2014

On September 18, we finished deploying the last OBS of line 2. To honor the last deployment, we did some decorating of the side float of the Scripps OBS.

The ships meet

September 18, 2014

The R/V Endeavor crossed paths with the R/V Langseth this afternoon around 16:45. The Langseth was shooting line 2 while the R/V Endeavor was heading back to the start of line 2 to begin recovery. Here's a picture of the Langseth aboard the Endeavor.

The Night Crew


September 18, 2014


No breaks from science! The Endeavor runs 24/7. When we are doing a line, we launch an OBS about every hour and a half from the ship. Here are some pictures on the night crew hard at work.

Ships crossing in broad daylight...

We passed the R/V Endeavor today as she steamed towards the southern end of this profile, where she will begin recovering OBS after the Langseth has passed over them, and the OBS have had a chance to record sound waves that turned deep below Earth's surface.  The Endeavor kept her distance to avoid disturbing all of the seismic gear that we are towing behind the Langseth!
