Abstract

The trip was from Los Angeles to Christ Church, New Zealand then to McMurdo, Antarctica and finally by helicopter to the Taylor Dry Valley for Lake Hoare and Lake Fryxell that are situated on opposite sides of the Canada Glacier. Over 2000 water samples were collected by pumping the water up through holes we drilled through the 15 feet of ice on both lakes. Half of the water samples were filtered and half of them were not. Samples were taken every half meter from the water just below the ice to the bottom, over 150 feet deep for lake Hoare and 70 feet for Lake Fryxell. Lake Hoare is a narrow deep lake and lake Fryxell is a shallower broad lake.  The water samples were analyzed for nutrients, sulfide ion, and for several metal ions including Fe, Mn, Cu, Co, Ni, Cd, Pb, and several rare earth metals. We are continuing with these analyses using a graphite furnace atomic adsorption spectrophotometer.  Other analyses made directly on the lakes were, pH, conductivity, temperature, dissolved oxygen, and sulfide ion Each analysis was made every half meter from the top to the bottom.  In addition, a sample of the bottom sediment was collected from each lake for analysis.

Graphs of temperature, oxygen concentration, pH and parts per million (ppm) or parts per billion (ppb) of each metal specie will be discussed where the analysis focuses on the depth profile, especially near the anoxic layer. The results of testing the bacteria species with several minerals and metal oxides will be given especially for some bacteria species on manganese dioxide where some of the bacteria consumes the metal oxide.

The conclusions will include goals we hope to achieve and things we hope to learn about these unusual natural laboratories that are free from agriculture, animal, human, and industrial waste. These lakes may serve as models of studies of how bacteria interact with lake waters that are not rich in biological material. The closing will include some of the surprises and experiences we had in Antarctica. Several of these experiences were not what we had expected.
 

About the Speaker

Joe Cantrell, a native of Kansas (a farm in southeastern Kansas), graduated from Emporia State University, then served in the Korean War. He returned and received an MS and a PhD from Kansas State University in 1960.  He worked as a Crystallographer for Proctor and Gamble at the Miami Valley Labs for 5years.  He then joined the Chemistry and Biochemistry Department of Miami University in 1965.  He has taught and carried out research primarily utilizing Crystallography for 35 years, directing several masters and doctoral students in this area. He has published over 100 articles in refereed journals, 15 book chapters and has over 200 published powder x-ray diffraction standards.  He has received about a quarter million in research grants through the years (some with colleagues).

His fields have been crystallographic and differential thermal analysis (thermal stability) of metal hydrides, organic and metal-organic complexes. He has traveled to China, Japan, Russia, Ukraine, Australia, Sweden, Germany, France, Greece, and Switzerland to give invited papers.  He is a member of an International Steering Committee in this area. He has served as an editor for the International Powder Diffraction Journal.

He has collaborated with Professor William Green of Miami University on analysis of the water in Dry-Valley Lakes that most recently were Lake Hoare and Lake Fryxell. Last December 1999-January 2000 he flew to McMurdo, Antarctica and went to the Taylor Dry Valley by helicopter where over 2000 water samples were collected and shipped back for analysis. He has been working on analyzing these samples with Joseph Shacat, a Miami student who also made the trip to Antarctica for the past 8 months. Joe's presentation will be based upon these results and some results of earlier years.
