ISEB 2019 mid-week field excursion - The tentative plan is to go to the Lausitz area southeast of Berlin. It is one of the world’s largest lignite mining areas; the open pits are so large they can be seen from outer space! Some of the abandoned pits have been flooded and recultivated, which causes some major biogeochemical problems, e.g. acid mine drainage etc. We will take a look at the “Hühnerwasser” (Chicken Creek), which is a model site for recultivation. On the way back to Potsdam we’ll stop at the UNESCO Biosphere Heritage Site “Spreewald”, a 475 km2 freshwater wetland. The area has been inhabited for several millennia and is a unique place to see how humans have altered and adjusted to the natural landscape. Please in mind that this as a very preliminary program, we can only sort out the details once we know the number of participants.

ISEB is pleased to announce a partnership with the European Association of Geochemistry.  The agreement offers benefits to members of both organizations.

A Graduate Student's Introduction to the International Biogeochemistry Scene

Brock Edwards, Department of Earth Sciences, University of Toronto, Canada

The 23rd International Symposium on Environmental Biogeochemistry (ISEB), which converged on tropical Palm Cove, Cairns, Australia in September 2017, was a great success. The symposium series has been in existence for nearly 50 years, occurring every two years and bringing together the best minds in the environmental sciences from around the world.

History of ISEB

The initial concept for this organization was developed in 1970 by D.A. McLaren and J. Skujins; specifically, a meeting with no overlapping sessions devoted to environmental biogeochemistry where participants would be exposed to discussions not only in their own field of expertise, but also to discussions in other cognate disciplines. 

Skujins subsequently organized an informal meeting in 1971 with P. Givens, T. Brock and H. Ehrlich that gave shape and form to the idea of a international symposium on biogeochemistry.  In 1973, the first symposium was held at Utah State University in Logan, USA.  Since then the symposium had become a regular biennial event with formalization of the organization through incorporation as a not-for-profit company under the name of Symposia on Environmental Biogeochemistry, Inc. (SEB).  At the 19th biennial symposium in 2009 at Hamburg, Germany, the International Committee of SEB established the International Society for Environmental Biogeochemistry.

ISEB 23 in Australia – an organiser’s perspective

Simon Apte, CSIRO Land & Water, Sydney Australia.

After two years of planning, the 23rd International Symposium on Environmental Biogeochemistry (ISEB23) took place in September 2017 at Palm Cove in far north Queensland, Australia. The location, which is a perfect showcase of tropical Australia with the Great Barrier Reef and rainforests being within easy reach, is an obvious attraction for any environmental scientist.

The organisers felt a strong responsibility to observe the tried and tested meeting traditions developed over 40 years that define an ISEB symposium. These included a four day single session program with a day in the middle for organised field trips and a comprehensive social program that is designed to maximise networking between delegates.  The Symposium attendance was deliberately kept small (around 100 delegates) as we wanted to offer an alternative to the large, impersonal mega-conferences where attendees often find it difficult to engage with fellow scientists and make new contacts. The ISEB meeting format has always encouraged networking and informal dialogue between delegates.

Membership is open to individuals who endorse the mission of the society and who are professionally active in environmental sciences, geochemistry, soil sciences, microbiology, limnology, marine sciences, atmospheric sciences, and all other related fields.  The two year length of memberships runs in parallel with the biennial cycle of the International Symposium on Environmental Biogeochemistry.
