Emerging Issues Workshop

Beginning with the summer meeting in 2010, the ASLO board of directors initiated funding for Emerging Issues Seminars that will further encourage dialog among scientists who wish to develop emerging, cutting-edge, controversial issues and/or topics that integrate knowledge across communities. In accordance with this, ASLO is sponsoring a two-day workshop following the meeting that is connected to a special session that will take place during the 2013 Aquatic Sciences Meeting in New Orleans. Organizers will submit a report with a summary of the outcome to the L&O Bulletin along with a table of contents of the written products stemming from the seminar.

ASLO 2013 Emerging Issues Workshop: Linking Optical and Chemical Properties of Dissolved Organic Matter in Natural Waters

Saturday and Sunday, 23 and 24 February 2013
08:00 to 17:00 - Belle Chasse Room, Hilton Hotel, 3rd Floor

This is an open workshop immediately following the 2013 Aquatic Sciences Meeting. The workshop will be held in the Belle Chase Room at the Hilton Riverside Hotel.

A substantial increase in the number of studies using the optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical properties has occurred during the last decade. This is due in part to improved instrumentation and algorithms for interpreting the spectral data. Chemical characterization of DOM involves intensive laboratory work and often large sample volumes, whereas optical characterization is attractive to many scientists as it is relatively simple and inexpensive and these techniques can also be measured in-situ and via remote sensing. Linking the optical and chemical properties of dissolved organic matter is now a topic that requires consolidation and a combined effort if the aquatic science community is to continue to gain from these techniques, which are becoming routine analyses in the aquatic sciences. The Aquatic Sciences Meeting has several sessions related to this topic. However, the workshop will address two specific urgent needs for utilization and proliferation of these techniques by the aquatic sciences community:

Link organic compounds (e.g. lignin) and classes of compounds (e.g. humic substances) present in natural waters that give rise to the spectral properties; and Link optical properties to sources and the wider biogeochemical properties of aquatic systems (i.e. the role that DOM will play in the aquatic ecosystem).

The workshop will begin with plenary speakers on Saturday morning and continue Saturday afternoon and Sunday morning with open discussions focused on several key sub topics related to these two over-arching needs. Confirmed plenary speakers who will provide overview talks for this workshop are: George Aiken, Ron Benner, Neil Blough, Paula Coble, and Antonio Maninno. The workshop will end early Sunday afternoon. A complete agenda will be announced prior to the meeting.
