2003 ASLO Aquatic Sciences Meeting

The Earth’s Eyes:
Aquatic Sciences Through Space and Time

February 8-14, 2003 · Salt Lake City, Utah

To paraphrase Thoreau, aquatic ecosystems are the landscape’s most beautiful and expressive feature(s). They are the Earth’s eyes; looking into which the beholder measures the depth of his own nature.” (“The Ponds,” Walden). This observation is extremely pertinent today, given the multitude of changes occurring on our planet and the significance of aquatic systems to those changes. Integrative historical and paleo studies help us better understand how the Earth system functions. Perhaps Winston Churchill put it best: “The farther backward you can look, the farther forward you are likely to see.” This semi-annual aquatic sciences meeting presents an opportunity to use our eyes to look into the past, to examine where we are today and to look forward into the future. We encourage sessions that develop themes along axes of time, including paleo, historical and modern studies, and space, from landscape, seascape or extraterrestrial perspectives.

Conference Check-In and Registration

Registration prior to the meeting is strongly encouraged. By doing so, you will greatly reduce the amount of time necessary to complete the on-site registration process and pick up your meeting materials.

Meeting materials and name badges can be picked up on Sunday, February 9, 2003, at the Salt Palace Convention Center from 1:00 to 9:00 p.m. Registration will be opened each day at the convention center, from Monday, February 10, through Thursday, February 13, from 7:00 a.m. to 5:00 p.m., and on Friday, February 14, from 7:00 a.m. until the conclusion of the conference.

Name badges will be included in your registration materials and must be worn at all times throughout the meeting. Your conference receipt will be included in with your badge.

Maps showing the various session and meeting room locations will be included in the abstract book that you will receive on-site when you check-in for the meeting.

General Meeting Overview

One of four planned plenary lectures will be held Monday through Thursday mornings and will be followed by a coffee break. Poster sessions and receptions are scheduled to provide a second opportunity to make professional connections in a social setting. Daily conference events will be held at the Salt Palace Convention Center. Please make plans to join us in Salt Lake City, Utah, USA, the site of the 2002 Winter Olympic Games!

Special sessions will be organized around the four following sub-themes:

Sub-theme 1: Historical Studies in Aquatic Sciences
Plenary presentation by Sherri Fritz, Department of Geosciences, University of Nebraska

Human activities have altered the Earth’s hydrosphere, biosphere and atmosphere. Documenting the impacts on, and the response(s) of, aquatic ecosystems to anthropogenic forcing is necessary both to understand past and present dynamics and to sustain aquatic environments and the resources they provide in the future. This sub-theme aims to cover a broad range of historical studies in aquatic sciences, including water quality and nutrient regimes, primary and secondary production, fisheries, harmful algal blooms, biodiversity, freshwater flow (surface and groundwater), dams and impoundments, watershed alteration and development, aquaculture, and invasive species.

Sub-theme 2: Paleo Studies in Aquatic Sciences
Plenary presentation by Don Canfield, Institute of Biology, University of Southern Denmark

The study of aquatic ecosystems over geologic time scales provides insight to the vital interactions that drive global-scale patterns of climate and biotic evolution at micro and macro scales. This sub-theme will encompass paleo studies in the context of the evolution of biogeochemical cycles and aquatic biota, glacial-interglacial cycles, ocean-atmosphere dynamics, mass extinctions, and global change.

Sub-theme 3: Spatial Patterns in Aquatic Systems
Plenary presentation by Jim Elser, Department of Biology, Arizona State University

Complex spatial patterns in aquatic systems occur at local, regional and global scales. These patterns result from dynamic interplays between biotic and abiotic forcing factors at small (sediment-water interface, connections between littoral and pelagic processes) to very large, global processes, such as ENSO events. Sessions in this sub-theme may include: watershed and regional oceanic responses to climate or anthropogenic forcing, emergent properties of aquatic ecosystems, biocomplexity, application of a regional landscape perspective to lake districts, or comparative studies of coastal ocean responses to perturbations.

Sub-theme 4: Extreme Environments On Earth and Beyond
Plenary presentation by Colleen Cavanaugh, Department of Molecular and Cellular Biology, Harvard University

The organisms that thrive in the conditions present in extreme environments may hold the key(s) to understanding life on early Earth, and elsewhere, as well as evolution of biogeochemical pathways. Sessions related to this sub-theme will examine distribution, physiology and diversity of organisms that thrive under harsh environmental conditions. Topics/habitats to be covered under this sub-theme include, but are not limited to: phylogenetic and functional diversity, extremophiles and extremozymes, symbiosis and syntrophy, deep sea hydrothermal vents and cold seeps, hot springs, polar environments, saline lakes, deep ocean environments, and systems beyond the Earth.
