Career stage (grad student, postdoc, faculty). Who is your advisor?

Graduate Student (Ph.D. Candidate).
Prof. John Harte (UC Berkeley) along with Drs. Margaret S. Torn (LBNL) And Jennifer
W. Harden (USGS – Menlo Park)

Why are you interested in this course?

I am interested in this course because my current and future research goals are mainly in
isotope ecology and geochemistry; specifically I am interested in pursuing research that
employs stable and radioactive isotopes of Carbon (along with Nitrogen, Hydrogen,
Oxygen Cesium and Beryllium in the gaseous and solid states) to understand the
dynamics of soil organic matter and soil water from molecular and chemical perspectives.
I believe this course will give me a much needed theoretical and practical background
into using 14C as a tracer for the carbon cycle between the different spheres.

How will this course influence your current or future research?

Part of my dissertation research needs to use 14C in order to infer stabilization of buried
carbon (effects of erosion and deposition) from:
    o Turnover time of soil organic matter and
    o Proportional storage of old vs. young C in different depositional basins (C-
        inventory weighed fraction modern)

And radiocarbon is one of the tools that I intend to use in my future work including, but
not limited to, soil microbiology and biogeochemistry along urbanization and pollution
gradients.

Are there particular aspects of the course that are of interest to you? Would you be
interested in attending the lecture course (theory) if there was not enough room for
you in the lecture and lab course together?

Career stage (grad student, postdoc, faculty). Who is your advisor?
PhD. - student under supervision of Prof. Dr. I. Kögel-Knabner

Why are you interested in this course?
In my current research I deal with the composition and turnover of soil organic matter in
forest soils. For the analysis of turnover processes of SOM the 14C age of SOM fractions
and of respired CO2-C is of particular interest to me. The radiocarbon analysis via AMS
to evaluate the turnover of organic matter is therefore one major task of my work.

How will this course influence your current or future research?
I expect from the course to get a better and more detailed understanding of sample
preparation and the use of AMS. This will help to optimize my own experimental design
to obtain accurate data. Furthermore I hope to gain experience in mathematical and
geochemical interpretation of 14C data. The interpretation of chemolytic and 13C NMR
spectroscopic data that I plan to obtain from forest SOM and SOM fractions will be much
improved by combining them with radiocarbon data.

Are there particular aspects of the course that are of interest to you? Would you be
interested in attending the lecture course (theory) if there was not enough room for
you in the lecture and lab course together?
The radiocarbon dating on a terrestrial background (pedosphere) is of special interest to
my research. Therefore I would definitely be interested in attending the lecture course.

Please describe your prior lab experience. Do you have any stable isotope lab
experience? Analytical lab experience?
I have experience in common soil analytical techniques e.g. C/N, texture and pH analysis.
Furthermore I have theoretical and practical experience in the analysis of SOM with solid
state 13C-NMR spectroscopy.

Please provide any other information that may be relevant to this course:
For the design of my further analytical approach I would like to discuss problems and
difficulties of SOM fractionation techniques with regard to obtain meaningful 14C pools.
Furthermore I am interested in radiocarbon analysis and interpretation of data from
respired CO2-C from soil incubation experiments..

Career stage (grad student, postdoc, faculty). Who is your advisor?
2nd-year grad student in Whendee Silver’s lab


Why are you interested in this course?

I am looking at the effects of nitrogen (N) deposition over topographic gradients in a
tropical forest in Puerto Rico. My central question is: Do plant species changes over
topography feedback on nutrient availability and soil carbon storage? I will be looking at
drivers in nutrient availability (soil oxygen and water drainage), and assessing if these are
also drivers of soil C storage and turnover. I aim to quantify how N deposition influences
soil carbon storage via changes in litter quality and microbial demand for carbon. I will
identify differences in baseline C stocks and ages at the different topographic locations. I
hope to use radiocarbon dating as a central method in my research. I will be dating
carbon stored in soils, roots, forest floor, and recently senesced leaves. I hope to use and
compare radiocarbon and root in-growth methods.


How will this course influence your current or future research?

I see this course as a way to branch out my research. Most of my research has focused on
nitrogen and nitrogen cycling. It is clear to me that more must to be done to understand
links between nutrient cycles. The carbon and nitrogen cycles have been studied
extensively, yet the links between the two are still unclear. Part of my research plan is to
scale field measurements up to a watershed-scale model of feedbacks between nutrient
cycles. Determining the effects of N deposition and cycling on C storage over tropical
landscapes seems integral to our projections of future C dynamics with regard to climate
change.
Are there particular aspects of the course that are of interest to you? Would you be
interested in attending the lecture course (theory) if there was not enough room for
you in the lecture and lab course together?

I am especially interested in the terrestrial radiocarbon portion of the course, and the
atmospheric portion will also tie in well with what I am doing.


Please describe your prior lab experience. Do you have any stable isotope lab
experience? Analytical lab experience?

I have worked analyzing total nutrient content of soils and plant tissues in Whendee
Silver’s lab. My work has involved using a GC, and ICP, and a C:N analyzer. I have no
lab experience using stable isotopes, though I have taken several lecture courses on stable
isotopes at UC Berkeley (with Todd Dawson and Ron Amundson). One of the attractions
of this course for me is the practical lab experience I would get.

2nd year PhD student

Why are you interested in this course?

I am interested in this course as my PhD research is focussing on the use of 13C
and 14C and associated respiration experiments in deciphering and interpreting
carbon cycling in peatlands.


How will this course influence your current or future research?

This course will broaden and strengthen my knowledge of carbon isotopes and
their role within ecology and earth system science. In addition, I hope it will aid
me in producing good, well thought out experimental work and enable me to
better interpret results from such research. I would very much like to remain in
this field of research after my PhD ends, and therefore would consider this
course important in both demonstrating my interest and commitment to doing
so.

Are there particular aspects of the course that are of interest to you?
Of particular interest to me is radiocarbon in the terrestrial biosphere part of the
course

Would you be interested in attending the lecture course (theory) if
there was not enough room for you in the lecture and lab course
together?
I would like to attend both parts of the course. However, I would probably gain
more from the lecture part of the course and would therefore still be keen to
attend if there were no room on the lab part of the course.

Please describe your prior lab experience. Do you have any stable
isotope lab experience? Analytical lab experience?

I have had analytical lab experience and some isotope lab experience. My
undergraduate degree was in Environmental, Agricultural and Analytical
Chemistry. My final year focussed on the phytoremediation of Polycyclic Aromatic
Hydrocarbons in soil (analysis by HPLC), and so therefore spent a lot of time and
gained a lot of experience in the analytical lab. The first year of my PhD focussed
on developing a molecular sieve (zeolite) sampling system for use in carbon
isotopic studies of soil respiration (at the NERC Radiocarbon Laboratory, East
Kilbride, Scotland). Once captured by the molecular sieve sampling system I
discharged and cryogenically purified the CO2 on a vacuum rig (on which I now
have some considerable experience), for analysis by IRMS and AMS.

Professor Trumbore is one of the experts in my field of research and therefore I
consider that attendance of this course would be of immense benefit to me.

Why are you interested in this course?
I am working with radiocarbon since my PhD, dating tree in Amazonia. I would like to
go deeper into radiocarbon technical. This course offers a unique opportunity to learn
more about this technique and bring this new information to my research group
improvement our research fields.



How will this course influence your current or future research?

This course will provide me a better basis theory and practical to work with this tool.
Since here in Brazil there are few research groups working in this field, there is a lack in
our scientific community. This course could offer the possibility to get more people
involved in this area.



Are there particular aspects of the course that are of interest to you? Would you be
interested in attending the lecture course (theory) if there was not enough room for
you in the lecture and lab course together?


I am interested in attend the lecture course and lab course because in our laboratory we
have conditions to install all equipments to prepare sample to radiocarbon analyses and
this is our intention with this course.

Please describe your prior lab experience. Do you have any stable isotope lab
experience? Analytical lab experience?


Yes, but not much. I had experience in AMS during the course “Stable isotope”, where
we prepared and analyses the samples of vine, vodka, beer to verify the adulterate.

Please provide any other information that may be relevant to this course:


This course will be to supply theory and practical knowledge about radiocarbon, besides
it is an opportunity to contact other research groups that work with the same tool. It is an
unique possibility of scientific collaboration with an international scientific community.

Career stage (grad student, postdoc, faculty). Who is your advisor?

I am currently in my second year of graduate study in the MIT/WHOI Joint Program, and
I am advised by Christopher Reddy (WHOI).


Why are you interested in this course?

I am interested in the sources and cycling of halogenated organic compounds (HOCs) in
the natural world. I hope to employ radiocarbon as a tracer of HOC sources, and so I will
need to perform extensive radiocarbon analysis. I feel that it is imperative that
researchers have a thorough understanding of the procedures required to prepare their
sample for analysis (as opposed to sending their samples to a preparative lab), and I hope
to develop those skills, as well as a better understanding of radiocarbon as an
environmental tool, during this course.


How will this course influence your current or future research?

This course will broaden my understanding of radiocarbon analysis, and in particular, my
understanding of and ability to carry out the preparative steps required for sample
analysis by AMS. This course will improve my ability to interpret my results and their
global implication/ significance. In addition, the skills that I acquire to efficiently and
precisely process my samples will be invaluable to my study of the transport of HOCs in
the environment.


Are there particular aspects of the course that are of interest to you? Would you be
interested in attending the lecture course (theory) if there was not enough room for
you in the lecture and lab course together?
The preparative skills that are taught in this course are of particular interest to me, so that
I may be able to perform the bulk of the preparative work required to perform
radiocarbon analysis on my samples by AMS. A one-week, lab intensive radiocarbon
class is a unique and ideal opportunity to gain and hone these skills that will be essential
to my work.


Please describe your prior lab experience. Do you have any stable isotope lab
experience? Analytical lab experience?

My laboratory experience with isotopic analyses is restricted to the 234Th method for
determining particle flux to the sea floor using a RISØ gamma counter. My analytical
career has involved fluorescence (N2-pumped, dye laser) detection, UV-visible
spectroscopy, gas chromatography (GC)/ mass spectroscopy, and GC x GC. I have
participated on two oceanographic cruises (R/V Oceanus 400, R/V Cape Hatteras 1204)
to collect multi-cores, gravity cores, CTD casts for 234Th flux data, and water pumping to
study the distribution of black carbon in the Gulf of Maine. I have some experience
flame sealing 12-mm quartz tubes on a vacuum line, but have never prepared samples for
analysis by AMS. (More detailed description of laboratory experience/publication list
available).

4th year Graduate Student, expect to complete within 6 months.
Advisor Peter B deMenocal, LDEO;
2 years of which as Guest Student with Tim Eglinton, WHOI.

Why are you interested in this course?
My research interests are broadly paleoclimate, geochronology and organic
geochemistry, please see www.ldeo.columbia.edu/~singram for more information.

Currently I study ecological variability in East Africa over 10Ma using d13C of n-alkanes
and n-alkanoic acids in marine sediments to reconstruct C3 v C4 vegetation changes. I
am interested in the radiocarbon work that helps to identify source differences in modern
sediments, in order to better interpret the paleoenvironmental record.

I have also worked on Holocene timescales in the same region (SSTs), where I obtained
radiocarbon dates on foraminifera, and incorporated radiocarbon ages into age models. I
sought some advice on radiocarbon reservoir ages for samples in the Gulf of Aden from
John Southon. I am interested in learning more about the d13C offsets between the
various component in the atmosphere and oceans. I am also interested in the molecule
specific radiocarbon data that shows the different ages of sediments in drift deposits
commonly used for paleoclimate reconstructions.

I am exploring new project ideas for postdoctoral work using organic geochemistry to
look at paleoclimate questions, most likely within the Holocene, where I could combine
molecule specific d13C and d14C.
I have heard great things about the Irvine group from Shahla Ali and Jomshik Huang,
who both used to work in your lab, and I am keen to participate in your course.

How will this course influence your current or future research?
Hopefully it will provide new tools, new information and new contacts to help shape my
postdoctoral research.

Are there particular aspects of the course that are of interest to you? Would you be
interested in attending the lecture course (theory) if there was not enough room for
you in the lecture and lab course together?
Yes, I’d be happy to just attend the lectures. My home is in Redondo Beach, so I will
also be happy to drive and therefore will not need accommodation to be provided. Since I
am familiar with molecule specific sample preparation for d13C, and have observed
others in the WHOI lab doing d14C sample preparation, I am most interested in the
theoretical aspect of the course, although I would appreciate learning the lab procedures
if possible.

Please describe your prior lab experience. Do you have any stable isotope lab
experience? Analytical lab experience?
