2011 Pavilion Lake Research Project Participants

Darlene Lim, Principal Investigator. Darlene is a geobiologist and limnologist (and yes, her last name is Lim) based at the NASA Ames Research Center. Her research interests span Earth and Space Science. She conducts limnological and paleolimnological investigations of remote lakes and ponds in the Canadian High Arctic to characterize Holocene climate change. She has also extrapolated her Arctic work to Mars analogue paleolake reconstructions. Since 1999, she has been participating in the NASA/SETI Haughton Mars Project, and was selected to inhabit the Mars Society's Flashline Mars Arctic Research Station (FMARS), the world's first Mars simulation base, at Haughton Crater in 2000 and 2001. She now sits on the Mars Society's Steering Committee.

Darlene led the establishment of the PLRP in 2004, and along with her co-PI, Bernard Laval, has enjoyed managing and evolving the project ever since. Her research interests at Pavilion Lake include its chemical and biological limnological characterization, and the isotopic biosignatures associated with the microbialites. She is also extremely interested in understanding the possible unique nature of Pavilion Lake through the exploration of near-by lakes and the regional geology.

Over the past decade, Darlene conducted fieldwork in the Canadian High Arctic, the Antarctic, throughout Central America, Guyana, and northern Chile. She continues to ardently promote the importance of science and exploration through lectures, media outreach and editorial contributions.

Phil Nuytten. An internationally recognised pioneer in the diving industry, Phil Nuytten has spent 40 years creating deepwater dive products that have opened the ocean's depths to exploration and industry. Through his companies, Nuytco and Can-Dive, he has developed the technology to allow longer-length diving expeditions with increased safety. Nuytten's one-atmosphere systems – the hard-suits 'Newtsuit' and 'Exosuit', and his deep-diving “DeepWorker” submersibles – are renowned internationally. This deep diving equipment, along with Nuytten's military submarine rescue system (designated 'Remora' by the Royal Australian Navy and 'PRMS' by the US Navy), is standard in nearly a dozen of the world's navies. Contract work has taken him to oilfields, submarine construction sites and sunken wrecks around the world, including the Breadalbane, the northern-most known shipwreck, where his record dives through icy Arctic waters earned him a place on the cover of National Geographic Magazine in 1984. Nuytten was one of the forces behind the 'Sustainable Seas Expeditions' in the 1990's, a five-year initiative by the National Geographic Society and NOAA to study deep ocean environmental impact. During this project, DeepWorker micro-subs were used to explore and monitor National marine sanctuaries. The findings from this expedition have contributed significantly to scientists' understanding of underwater ecology, habitats, and biodiversity. More recently, Nuytten and his team finalized development of the 'Prehensor', a prosthetic-like device that mimics the human hand and will allow manipulative dexterity far in advance of the current pliers-style end effectors. The 'Prehensor' is being integrated into the development of an ultra light weight, swimming hard suit called the 'Exosuit', giving the operator the best of both worlds: the safety of a rigid one-atmosphere system along with the manual dexterity of a scuba diver's gloved hand. NASA has shown considerable interest in this technology for use by astronauts in space. Phil Nuytten has spent nearly forty years developing undersea systems that have the safety of the diving technician as their common theme. His goal has been to provide scientific, technical, military, and sport divers full access to continental shelf depths without the hazards of decompression, so that humans can explore, learn about, and - ultimately - protect the world's oceans.

Joe Russell, Microbiology. I attended the University of Arizona and began college as an astronomy major. A part time job in the labs of Dr. Chris Impey and Dr. Neville Woolf introduced me to astrobiology, origin of life research, and molecular/microbiology in general. After developing a fascination of the intricacy and diversity of microbial life, I switched majors to microbiology. For the remainder of my undergraduate career I worked in the Human Origins Genotyping Lab processing samples for National Geographic's Genographic Project in an effort to study the human journey out of Africa through DNA. I completed a Bachelor's in Microbiology in 2008. After working in the bio-tech industry in Boston for 2 years as well as a fortunate 2 month stint on an oceanographic research vessel in the Pacific, I relocated to Lewes, Delaware where I am currently pursuing a PhD in marine microbiology at the University of Delaware under Dr. Jennifer Biddle. My research focuses on the microbial ecology and metagenomics of unique and extreme environments such as the microbialites of Pavilion Lake and sub-seafloor sediments. With PLRP, my main focus is understanding how differing bacterial communities comprising the microbialites affect the morphology of these structures as well as the differences in microbiology of lithifying vs. non-lithifying microbial mats.

He has extensive experience leading and coordinating multi-organization communications and networking teams, and architecting and executing complex operational communications systems and networks. 

 

 


Gregory Slater, Organic and Isotope Geochemistry. I am currently an associate professor and Canada Research Chair in Environmental Isotope Biogeochemistry at McMaster University. My research focuses on the use of multiple compound-specific isotope analytical techniques to investigate and constrain the sources and cycling of organic compounds in environmental systems. I am particularly interested in the identification and interpretation of biosignatures of microbial organisms and the implications that this has for our ability to interpret the history of life on earth in the geologic record, and to search for signatures of life on other planets,such as Mars. Pavilion lake, and the nearby saline, alkaline evaporitic lakes of the Cariboo plateau provide a unique opportunity to investigate the biosignatures of modern microbial systems. My group is characterizing the geochemical and isotopic signatures of these systems, particularly the carbon sources, microbial cellular components and metabolic byproducts of the organisms that are living on the surface of the microbialites and as thick microbial mats in the Cariboo lakes. By understanding these systems and the geochemical and isotopic signatures associated with them, we can not only increase our knowledge of the capabilities and activities of life, but also build the foundation necessary to interpret geological and/or astrobiological samples.

Dawn Sumner, Participating Scientist. Dawn Sumner became interested in geology as an undergraduate at California Institute of Technology. With extensive research experience with Prof. Joe Kirschvink, she earned a Bachelor’s of Science with Honors in 1989 and moved to Massachusetts Institute of Technology supported by a National Science Foundation Graduate Student Fellowship. She spent her time at MIT working with Prof. John Grotzinger (and others) on 2.5 billion year old carbonates in South Africa, as well as several side projects. Dawn finished her Ph.D. in Geology in 1995, after which she returned to California Institute of Technology as an O.K. Earl Postdoctoral Fellow. In December 1996, Dawn joined the Faculty at University of California, Davis, as an Assistant Professor of Geology. She was promoted to Associate Professor with tenure in 2002, was named a Chancellor’s Fellow in 2003, and was promoted to Full Professor in 2006. In recent years, her research has expanded beyond Archean carbonates to include microbial-mineral interactions of all ages, experimental biofilms, and Martian geology. Several specific projects relate to research at Pavilion Lake. Student Bekah Shepard and Dawn are studying how cyanobacteria organize into complex structures such as some of those found in Pavilion Lake. This research involves both experimental cyanobacterial biofilms (http://geology.ucdavis.edu/~sumner/modernmicrobes.html) and comparisons to natural mats, including those at Pavilion Lake. In addition, they are studying how microbial metabolic activity affects carbon isotopic signatures in carbonate, which can act as a geological record of microbial processes. Results from these modern studies provide a framework for interpreting ancient microbialites. Specifically, similarities between modern and 2.5 billion year old microbialites from South Africa suggest that the ancient structures record significant, but as yet unknown, microbial behaviors.

 


Art Trembanis, Visiting Scientist and AUV team participant. I am interested in pursuing the goal of repeated high-resolution lake bottom mapping from the platform of an Autonomous Underwater Vehicle.
