    In late April 2009, a team of MBARI researchers tested the world's only deep-sea robotic DNA lab beneath the waters of Monterey Bay. This instrument is the latest version of the Environmental Sample Processor (ESP), which MBARI molecular biologist Chris Scholin has been developing for over 10 years. The ESP is a self-contained robotic laboratory that collects samples of seawater and tests these samples for different types of genetic material, such as DNA.

    Over the last several years, Scholin and his team have used the ESP to study microscopic marine life near the sea surface in Monterey Bay. However, adapting the ESP to work in deep water added new challenges to what was already a very complicated project. Because of the immense pressure in the deep sea, the researchers had to build a special pressure housing to protect the delicate instrument. They also had to design and build an automated system to "depressurize" seawater before it could be introduced into the ESP.

    Later this spring, the deep-ESP team will test the instrument for several days in water about 2,900 meters deep, offshore of Monterey Bay. In August, 2009, the deep ESP will be deployed for its first scientific mission - to study microorganisms near hydrothermal vents off the coast of Oregon. Later in 2009 it will be hooked up to the MARS undersea observatory, which will allow the team to run experiments and gather data from shore.

Team Overview Seminars: Each of the NAI teams will be giving one hour overview seminars that describe the work they will be performing as members of the NAI. These seminars, which will be broadcast via videoconference and web, will provide an opportunity to find out more about the science, EPO and other activities being performed by the NAI teams.

The Director’s Seminar series features talks from scientists who are invited by the NAI Director to present their research results to the community. A primary goal of the seminars is to encourage interdisciplinary collaboration across NAI teams and within the astrobiology community at large. These seminars are open to all, including the general public; however, the target audience is researchers and students who are engaged in astrobiology. While the seminars are technical in nature, speakers are encouraged to develop presentations that can be understood by colleagues from a variety of disciplines across the field. The talks are typically 50 minutes long, with time at the end for questions and discussion.

The Forum for Astrobiology Research (FAR) seminar provides an opportunity for graduate students to present their research results, and to meet as a student community for mutual encouragement and support. FAR science presentations are typically 20-30 minutes each, with several students presenting during one virtual event. On occasion, the FAR seminar will be devoted to group discussion and planning activities.

The University of Washington seminar series is hosted by the NAI VPL team from their campus in Seattle. NAI provides technical support for the seminar series and produces podcasts of the presentations. The talks are typically 50 minutes long, with time at the end for questions and discussion.

Other virtual seminars, such as workshops and summer student presentations, are hosted by NAI. These are typically scheduled as needed and vary in length, content, and target audience.
