Happy Holidays from RML

Hope you are all having wonderful holidays. In the midst of winter, we’d like to thank you (particularly our volunteers and committee members) for a wonderful year and all you’ve done to help make the Rutledge Marine Lab  amazing in 2013. We look forward to a great year ahead and seeing you all on Star Island.

As thanks, I wanted to share with you this good cheer from our friends over at the Woods Hole Oceanographic Institution (WHOI). WHOI engineer Justin Fujii used electrical tape and a little magic to make the AUV Sentry resemble a certain jolly old elf!

Scientists from the University of Alaska Fairbanks, University of California Santa Cruz and Moss Landing Marine Laboratory have been using Sentry and other ROVs to sample fluid emitted from a hydrothermal system called the Dorado Outcrop on a three-week cruise off Costa Rica.

The Dorado Outcrop is located within a 14,500-km2 region of cool seafloor, where 60–90% of the lithospheric heat is removed advectively. In other words, this seep is a relatively “cool” (10–20°C) fissure from which heated water issues (at least compared to other such sea floor vents). Often life thrives in such places.

In keeping with the holiday spirit, our committee has asked for donations of the following items to help the lab continue to improve this coming summer.

– A new desk-top computer
– Plankton nets
– Any fishing gear
– Masks and snorkels (nice ones for adults)
– An open ROV kit
– Dissolved Oxygen meter
– Flat screen television
– Audubon field guides for seashore animals, invertebrates and fish in the North Atlantic

Atlantis returned with “Santa Sentry” to Costa Rica December 23, just in time for Christmas. Sentry is an example of an autonomous underwater vehicle (AUV) that operates without requiring input from a remote operator or needing to be “tethered.” In contrast, more common remotely operated underwater vehicles (ROV) are tethered to a ship for operation.

Happy holidays everyone.
