Physics of Environmental Archives

 

Radiocarbon Laboratory
Carbon dioxide extraction from speleothem samples and carbon graphitization to trace the past global carbon cycle
Cold-water Corals
Reef-forming cold water corals are a unique archive to study the climate and dynamics of the present and past ocean
Th/U Laboratory
Preparation of the samples for high-precision Th/U dating requires the chemical purification of both trace elements from natural samples
Speleothems
Stalagmites are an important archive to study past continental climate via stable and radioactive isotopes, based on ultra-high precision chronologies
Ocean Tracers
Climate driven cycles of heat and carbon in the ocean are studied through the use of trace isotopes such as radiocarbon
Masspectrometry
Preparation of high-precision isotope measurements with semi-automated multi-collector inductively coupled plasma mass spectrometers
U-Isotopes
234U/238U ratio of seawater since the last ice-age as measured through U-series dating of cold-water and tropical corals traces continental freshwater runoff

Physics of Environmental Archives studies present and past climate. Ultra-high precision U-series- and Radiocarbon dating (the later in cooperation with the Curt Engelhorn Centre for Archeometry) yields timing and phasing of past climate events and the depositional history of climate archives. Trace elements and rare isotopes allow us to fingerprint climate system properties, processes, and biogeochemical cycles. In some easy physics words we search for the functions of climate variables X(t,r) and the climate sensitivity of λ(X) beyond the time scales of modern observations.

Research

View on the ROV observation board

Our scientific projects benfit from support of the German-Science-Foundation (DFG). Details on presently running and former projects are here DFG-GEPRIS. The Heidelberg Graduate School of Fundamental Physics sponsors PhD fellowships and supports schools and conferences and most importantly creates an unique environment to grow and experience science. The folloing four research projects are driving our curiosity and enthusiasm

(1) Past Thermocline Ocean Dynamics

ROV operation to find corals

Geochemical proxies and chronometers stored in the skeletons of corals provide measures of water mass dynamics throughout the Atlantic. We work with cold-water coral species, which build reefs that can provide semi-continuous records of past climate change at unprecedented age precision.  Our most valuable tracers are radiocarbon, Nd-isotopes, and the Li/Mg ratio offering information on the state of ventilation, water mass provenance, and temperature. We are interested in many other geochemical and isotope tracers to study nutrient cycling, continental discharge and weathering. We conduct this work in the frame of natianl and international cooperation. For example Freya Hemsing developped the Ba-Isotope toolbox as part of her PhD, during a DAAD funded stay at University of Oxford [Hemsing, 2018].

view of the inductively coupled plasma source mass spectrometer laboratory

Pushing the analytical limits of modern mass spectrometry and developing new routes towards accurate U-series chronologies of climate archives including laser ablation Th/U dating is a major aspect to advance past climate science through better chronologies. This project is absolutely central to all other research subjects.

(3) Past Ocean Dynamics viewed through Marine Sediments

sediment coring

Since the late 90's the radiogenic isotope ratio of 143Nd/144Nd has become an important tool in paleoceanography to trace deep ocean circulation and water mass provenance. Marine sediments are excellent archives of this tracer. We investigate sediment cores from ocean seafloor drilling sites to retrieve the dyanmic of εNd in the deep Atlantic Ocean over climate cycles. Our ongoing projects funded through the DFG SPP International Ocean Discovery Program (IODP) are:

(4) Quantitative Speleothem Climate Reconstructions

speleothem sampling with diamant saw

The fourth cornerstone of our research is the reconstruction of past climate variability using cave deposits, i.e. stalagmites and flowstones, but also other secondary carbonates, such as travertine and carbonate tufa. Speleothems have become most valuable climate archives since they can be precisely dated and provide a wealth of proxy records spanning timescales from (sub)-annual to orbital. Only few  proxies deliver quantitative climate reconstruction and  allow for modelling. We have concentrated on the chronology and the use of radiocarbon (14C) as a tool to calibrate atmospheric 14C, and to detect past vegetation and soil carbon cycle dynamics. Based on the success of the former DFG research group Daphne, we have advanced stable isotope and radiocarbon modelling, we continue cave environmental monitoring.

Dr. Sophie Warken joined the team to start a new frontier towards the potential of speleothems from Cueva Larga (Puerto Rico) as recorders of subannual hurricane activity. This initiative was supported by a startup grant of Heidelberg University. Most importantly, this central project is conducted in collaboration with Prof. Wolfgang Stinnesbeck to explore the links between climate and its impact on the ancient Mayan societies and local hydrology and sea-level, as well as on late Pleistocene/early Holocene faunal occupation on the northern Yucatan peninsula (Mexico).

INFRA-STRUCTURE

To conduct our research, we have build a large infra-structure including several mass spectrometers and clean laboratories. The technology was funded by the State Baden Württemberg and the DFG and relies on the support of its users.

Environmental Trace Isotope Infra-Structure - Part I

(DFG INST35-1143FUGG and S & I fond Baden Württemberg / 2015)

the way to a new lab in a few image thumbs

A new Laser - Ablation multicollector inductiely coupled plasma source mass sprectrometer facility (LA-MC-ICPMS) was established in Heidelberg. Various laboratories have been refurbished and equipped with a ThermoFisher Neptune-plus and New Wave 193 Laser Ablation system. Further equipement include an inductively coupled plasma source quadrupole mass spectrometer (ThermoFisher iCAP-Q) and an Elemental Scientific Prepfast System for automated chemistry. We conduct research on ultra-high precision Th/U dating and high precision U-isotope measurements using these instruments and we develop rare isotope tracers including stable and radiogenic isotopes of Ba, Nd, Sr, Th, and Pa. Many others are feasible including B and Li isotopes. Numerous publications demonstrate the success of this infrastructure to determine the timing of archive construction and the environmental conditions of past ocean dynamics or matter and energy transport through the climate system. The short report on the first 3 years use of the instruments can be found here.

Environmental Trace Isotope Infra-Structure - Part II

(DFG INST35-1270FUGG and S & I fond Baden Württemberg / 2015)

IRMS Thermo FIscher MAT253

A new isotope ratio mass sprectrometer with a particular multi-cup system and coupled to a Gasbench II was established in Heidelberg. With this new infrastructure we conduct research on stable carbon and oxygen isotopes in carbonates and air. The instrument is further used by the teams of Dr. Tobias Kluge and Dr. Martina Schmidt to conduct clumped isotope studies of carbonates and atmospheric air isotope measurements. The short report on the first 3 years use of the instruments can be found here.

Teaching

Norbert Frank Experimental Physics 1

We teach in both Physics and Earth Sciences. Statistics (and R programing) is developed by Martina Schmidt and 'The Physics and Chemistry of the Ocean' is part of our training in geochemistry. In Physics, our focus is clearly 'Environmental Physics' (MKEP4). The bachelor seminar on 'Isotope methods in Environmental Physics' and the practical excercise (F55) 'Rayleigh fractionation' has become a very successful series. Our course program is on LSF.  And a detail List and description (however without the script, movies, and other material) can be found here.

The physics, earth science and general scientific training of students is, however, best done through exciting science projects, which constitute a very significant effort of our teaching program (see the list of accomplished projects below). If you want to get involved? Do not hesitate to get in touch with us - see people !

Puerto Rico (Larga Cave) 2019

In March 2019 Sophie Warken and Rolf Vieten (Hebrew University Israel) took three students to Puerto Rico to take up scientific work on the Hurrican imprint on the geochemical and isotopic composition of cave drip water and speleothem carbonate. During the field trip numerous carbonate deposits have been investigated, drip water collected, and the cave was further explored for its scientific value. This project was funded by Heidelberg University to initiate a work program leading to a new scientific proposal.

Logo Athena Ausfahrt Research Cruise M151 - ATHENA

From the 6. October to the 31. October 2018 the RV Meteor explored the slopes of the Azores and its southwestern seamounts, including Great Meteor Seamount, as part of the ATHENA research project. A scientific team composed of marine biologists, geologists, and environmental physicists were on board to collect seawater, sediment and fossil cold-water corals ultimately to reconstruct past thermocline water and ecosystem dynamics. Find our  weekly reports . here, and further information on the scientific cruise report will appear soon. Lasty there is a cruise blog with some short stories in German at MARUM

Logo UFO Ausfahrt  Research Cruise M141-2 UFO

From the 5. October to the 19. October the RV Meteor transits from the Azores to the Black Sea through the Mediterranean Sea. We, Evan, Norbert, Marleen and Patrick join the cruise to collect seawater that would allow high precision measurements of geochemical constituents, in particular the natural isotopic composition of U. It has been proposed that the natural 234U/238U ratio may serve as a tracer of continental weathering. We intent to collect water in a few places study the difference between Atlantic and Mediterranean seawater. Hopefully, this will allow to obtain a new fingprint of Mediterranean continental weathering. A second part of our scientific program concerns the measurement of the solar attenuation including the effect of water vapor. This part will be conducted by a colleague from the NASA's AERONET group. Find more information about the solar attenuation measurements on the webside of the maritime aerosol network.

The Labs and instruments

We make use of numerous techniques to study, describe, store and document the material we work with. Our repository contains corals and speleothems from all around the world. Once prepared we use mass spectrometric instruments, such as thermal ionization mass spectrometry and laser-ablation coupled to multi-collector inductively coupled plasma source mass spectrometry (short: LA-MC-ICPMS) or high sensitivity inductively coupled plasma source quadrupole mass spectrometry to measure element and isotope composition of our samples. Look up the service section for the analysis we can provide through scientific cooperation and if you want to learn more see the publications or get in touch .

Images from previous research cruises and field trips

The team participates in field work to collect samples from all around the world. The photos are snapshots providing a glance on what it is like to be on sea. The remotely operate vehicle (ROV) Victor 6000 belongs to the marine research infra-structure IFREMER and all rights on using those photos belong to IRFREMER and the cruise chief scientist.

Team events ...

We celebrate our scientific success and invest in a strong team through group events and group retreats. In 2019 we just have been in Bussang (France) funded by the Wilhelm und Else Heraeus-Foundation for a retreat regarding team theories and management including some new science. In 2018 we have had a field trip to the Eberstadter cave. In 2016 we have visited the waterfalls of Bad Urach . In 2015 we have spent a few days on scientific writing funded by the Wilhelm und Else Heraeus-Foundation for which we stayed at the KLJB Bildungshaus Fiegenstall . The year before we went caneoing on the Elsenz and bowling and sometimes we just celebrate remarkable events such as the 40 years of environmental physics.
