#AGU21 Get Your Abstract Ready!

Fall Meeting Programming Committee (Avni Malhotra (Incoming Chiar), Ben Runkle (Outgoing Chair), Laura Meredith, Forrest Hoffman, Min Chen)

Hey B-section!,                                                  

Are you excited about the #AGU21 biogeosciences sessions? Abstract submission is open!

For a general overview of the 90+ sessions proposed this year by your B community, check out our word cloud below of all the submitted session abstracts.

At this time, AGU is planning the 2021 Fall Meeting as a "hybrid" meeting, aimed to optimize both in-person (New Orleans!) and worldwide virtual participation. Check out #AGU21 for further information.

Elise Pendall (President), Margaret Torn (President-Elect), Jennifer Pett-Ridge (Secretary) 

Greetings from the Biogeosciences Section,                                                  

We are thrilled to welcome Colleen Hansel as the Biogeosciences Section President-elect, and Sean Schaeffer as our new section secretary. Join us at Fall Meeting Biogeosciences Recognition Celebration and you'll get to meet them!


Preparing for the 2020 Virtual Fall Meeting

Mark your calendar for our Biogeosciences Section Events:

1) Early Career Networking and Mentoring Event, 2-3pm, Pacific Time, Tuesday Dec 1

2) Recognition Celebration 1-2pm, Pacific Time, Thursday Dec 3

3) Carl Sagan Lecture (B069), 10:30-noon, Pacific Time, Friday Dec 11

The Carl Sagan lecture features “Earth System Perspectives Inspired by Carl Sagan” by Compton Jim Tucker and an early career panel discussion moderated by Dennis Ojima.

: Use the agu.confex scheduler as your home for planning. There is NO mobile meeting app this year! Additional attendee information tutorials and other resources are here: https://agu.org/agu20.

 Poster summary sessions will be held via Zoom. For individual sessions—you can choose a text chat or live chat. If you choose “live”, you will need to use your own Zoom account. Presenters can designate their time to be available for text/live chat within iPosterSessions, which will show up in the online program.

Closed Captioning for Talks: 
AGU tested several options and chose Google’s AI product. All uploaded videos will be run through this service. Captioning can be turned on/off by the viewer.

Renewing your #AGU membership? Consider donating to the Biogeosciences Section fund for the Hilker Early Career Award for Excellence in Biogeosciences! Even $10 will help establish the endowment.

Congratulations 2020 Biogeosciences awardees!

We are thrilled to congratulate the Section affiliates who were selected this year for Union Awards:

Union awards to Biogeosciences affiliates:

Simpson Medal: Asmeret Asefaw Berhe

Ambassador Award: Erika Marin Spiotta

Macelwane Medal: Kelly Wrighton

Union Fellows, AGU’s highest honor:

Edward Dlugokencky (NOAA Earth System Research Laboratory) has led NOAA’s global CH-4 measurement program for nearly 30 years. A preeminent authority on atmospheric chemistry and greenhouse gases, Dr. Dlugokencky is responsible for most of what we know about the contemporary global atmospheric CH4 cycle.

Paul J. Hanson (Oak Ridge National Laboratory) is a terrestrial ecosystem ecologist and leader of many innovative, large-scale manipulative climate change experiments with breakthrough discoveries--particularly FACE elevated CO2 studies and SPRUCE (Spruce & Peatland Responses Under Climatic & Environmental Change).

Kate Lajtha (Oregon State University) is a biogeochemist widely known for her work on stable isotopes in ecology, long-term soil C and N cycling studies, and leadership-- especially to the B-section! Dr. Lajtha is leader of the ‘DIRT’ experiments and has been Editor-in-Chief of Biogeochemistry for >15 years.

Bill McDowell (University of New Hampshire) is a watershed biogeochemist focused on production and transport of dissolved organic carbon (DOC), N fluxes in groundwater, effect of hurricanes on stream chemistry, and integrating terrestrial-aquatic interfaces in the global Earth system, particularly at the Hubbard Brook Experimental Forest, in New Hampshire, and the Luquillo Critical Zone Observatory in Puerto Rico.

Isabel Patricia Montañez (University of California, Davis) is a sedimentary geologist/geochemist, with breakthroughs in paleoclimatology that span the geological timescale, carbonate stratigraphy and diagenesis, low-temperature marine isotope geochemistry, terrestrial geochemistry and paleoclimate.

Josep Penuelas (Spanish National Council of Scientific Research) is recognized for his innovative research on global change ecology, remote sensing and atmosphere-biosphere interactions has had enormous impact. One of the most cited biogeoscientists and ecologists in the world, and a treasured collaborator to many!

Hanqin Tian (Auburn University) is a leading expert on atmospheric & terrestrial budgets of biogenic greenhouse gases (GHGs) and how they're affected by human activity. One of the first Earth System modelers to integrate GHGs into one framework, w/ a process-based N cycle, remote sensing & non-linear interactions.

Finally, congratulations to several friends of the B-section who became Fellows this year!!

William D. Collins, Lawrence Berkeley Lab, UC Berkeley

Rita R. Colwell, University of Maryland, College Park

Noah S. Diffenbaugh, Stanford University and Stanford Woods Institute for the Environment
