Ammonia-oxidizing archaea (AOA) dominate microbial communities throughout oxic subseafloor sediment deposited over millions of years in the North Atlantic Ocean. Rates of nitrification correlated with the abundance of these dominant AOA populations, whose metabolism is characterized by ammonia oxidation, mixotrophic utilization of organic nitrogen, deamination, and the energetically efficient chemolithoautotrophic hydroxypropionate/hydroxybutyrate carbon fixation cycle. These AOA thus have the potential to couple mixotrophic and chemolithoautotrophic metabolism via mixotrophic deamination of organic nitrogen, followed by oxidation of the regenerated ammonia for additional energy to fuel carbon fixation. This metabolic feature likely reduces energy loss and improves AOA fitness under energy-starved, oxic conditions, thereby allowing them to outcompete other taxa for millions of years.

The LA Times: Why tiny microbes may be a big factor in how climate change unfolds - NEW!
Climate change is about big things: melting ice sheets, rising seas, the feverish temperature of the planet. But scientists say it’s also about little things — namely, microbes. Like all life forms, microbes will feel the impacts of climate change. The way they respond could have huge implications for the rest of us. For instance, microbes will help determine whether natural sources of greenhouse gases rise or fall in a warming world. And they are key to ecological resilience in the face of environmental stress. That’s why a group of scientists issued a consensus statement calling for more research on the topic in this week’s issue of Nature Reviews Microbiology. Ominously, they called it ”Scientists’ Warning to Humanity.” The Times spoke with Victoria Orphan, a microbial ecologist at Caltech who helped write the statement, about why we shouldn’t overlook microbes.


Education & Outreach

IODP-USSSP: Volunteer or Nominate a Colleague to be an Ocean Discovery Lecturer, 2020-2021 - NEW!
The U.S. Science Support Program for IODP is currently accepting nominations for the 2020-2021 Ocean Discovery Lecture Series. For over 20 years, the Ocean Discovery Lecture Series (formerly the Distinguished Lecturer Series) has brought the exciting scientific results and discoveries of the International Ocean Discovery Program (IODP) to academic research institutions, museums, and aquaria. Since 1991, over 1,000 presentations to diverse audiences have been made through the Lecture Series. Lecture topics range widely, and include monsoon history, ice sheet dynamics, sediment diagenesis, and more. To learn more about the Ocean Discovery Lecture Series and the current lecturers (including deep biosphere researchers Ginny Edgcomb and Brandi Kiel Reese), visit the USSSP webpage. Nomination deadline: July 5, 2019.

Meetings & Activities

IODP-USSSP: Letter from the Co-Chairs, NEXT Steering Committee - NEW!
On May 6th and 7th, 88 U.S. scientists with a strong interest in scientific ocean drilling (SOD) convened a workshop in Denver, CO, entitled “NEXT: Scientific Ocean Drilling Beyond 2023” to discuss United States priorities for SOD after the current IODP science plan ends. Joining the workshop were several representatives from the JOIDES Resolution Science Operator (JRSO), experts in drilling/coring, geoscientists from other organizations, and about 30 international partners. In total, approximately 140 people participated. Goals of the NEXT workshop included: What new scientific challenges should be addressed in the new SOD program? What should the framework or structure of the new science plan look like? And what is needed in a new U.S. riserless drilling vessel (from coring to shipboard analysis) to respond to the new challenges identified in this next science plan?

Ongoing Activities:


Proposal Calls

IODP: Apply to Sail on IODP Expedition 386
The deadline to apply is July 5, 2019.

NSF: Faculty Early Career Development Program (CAREER) - NEW!
The Faculty Early Career Development (CAREER) Program is a Foundation-wide activity that offers the National Science Foundation’s most prestigious awards in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization. Activities pursued by early-career faculty should build a firm foundation for a lifetime of leadership in integrating education and research. NSF encourages submission of CAREER proposals from early-career faculty at all CAREER-eligible organizations and especially encourages women, members of underrepresented minority groups, and persons with disabilities to apply. Full proposal deadlines: July 17-19, 2019.

IODP: Apply to Sail on IODP Expeditions 390/393

UNOLS: Cruise Opportunity Program - NEW!
The primary goal of the UNOLS Cruise Opportunity Program is to provide graduate students currently completing (or who have recently completed) a degree in a field of oceanographic research with the opportunity to participate in a research cruise. The participant will be a member of the scientific party and be involved in data collection and all other activities at sea. It is envisioned that the individual will be familiar with the science to be conducted at sea, and thus, form new collaborations and potentially develop new research directions. To be eligible to participate in this program, the individual must be either currently be studying at a U.S.-based institution or a recent graduate, and must have either a U.S. Passport or a U.S. Work Visa. Please note that you are responsible for paying for your travel to/from the ship (unless otherwise noted), and at this time the UNOLS Office is unable to provide travel funds; however your advisor or institution may have some ideas.
