I’m so excited, and I just can’t hide it

Posted on July 15th, 2011 by Darlene Lim

When Dana Lis, our PLRP Education and Public Outreach coordinator, asked me to write a blog about how I was feeling, the first word that popped into my mind was – EXCITED! After months of planning, testing and organizing we are finally ready to start our adventure, and I am so looking forward to it all.

We now have nearly 200 participants on the PLRP team, and each year thousands of work hours go into preparing for our DeepWorker Science and Exploration (DSE) field deployment. Planning starts pretty much as soon as we end the prior year’s field program. This year’s deployment at Kelly Lake is no exception.

What’s in store is our most ambitious and operationally complex field program yet.

Throughout this coming week’s activities, we will continue our scientific exploration of microbialite rich lakes using such exploration tools as DeepWorker single-person submersibles and SCUBA diving. This research builds upon the work we have been conducting at Pavilion Lake, which is about an hour’s drive away. However, the team’s research doesn’t stop there. Our DSE program requires the integration of scientific methods, and operational and technological advancements. From these real field science activities, NASA scientists are learning about what it takes to conduct safe, productive and discovery-based science in extreme environments. It is this knowledge that will form the basis of future exploration concepts for human research voyages to such destinations as Near Earth Objects (NEOs) and Mars. With the end of the Shuttle program, this and other analog programs, such as Desert RATS and NEEMO, truly becomes NASA’s bridge to future space flight.

The entire PLRP is personal passion, so it is not surprising that I am extremely excited to get our 2011 field program underway.  But beyond the research, I’m excited to see the incredible scientists, engineers, operations experts, astronauts, and teachers who have become part of the PLRP family.  I’m thrilled to meet new colleagues who join us for the first time this year, and to thank the Clinton and Kelly Lake community for all of the support and assistance that they have already provided to the PLRP.

I remember when I was a kid that if something got me really excited I would jump up and down with joy.  Well, you know how it is, you kinda have to park that behavior through Junior high and high school, so I did.  But I find myself rekindling that jumping behavior these days each time I hear about some new finding or technical development or outreach opportunity that the PLRP team members come up with.  Happily, my NASA colleagues seem ok with me bouncing up and down periodically.  It is a joy, it is a privilege, to be part of the PLRP family.  And I hope that everyone reading our blogs will feel like they are part of the adventure too.

When there’s a camp cook… PLRP 2009 Closing Remarks

Posted on July 24th, 2009 by Darlene Lim

A while ago, Donnie Reid said something to me that went something like this: “When there’s a camp cook, that’s when you’ve got a real field camp on your hands”. He said that to me as we cheerfully prepared a modest dinner of salad and spaghetti for a hungry band of about 8 people. He was volunteering his diving skills to our research efforts, and me, I had just started at NASA Ames and was keenly exploring my new research site of Pavilion Lake. That was August 2004.

Welcome to July 2009 – and guess what? We have a camp cook. Her name is Dana. And she now prepares a mean pasta dinner for a thriving (and still hungry) camp that has grown to almost 60 characters from all walks of life and from all over the world. Oh, and as for Donnie, well he is now the PLRP Logistics and Operations Manager and is in charge of organizing the activities of everyone from the astronauts to yep, the camp cook. I think he knew this was coming when he said what he said to me some years ago.

When I think back, I’m struck by the fact that the project has seen more faces come than go, and as a consequence, we’ve grown. Folks keep coming back, and bringing more folks with them. It’s great, because with each passing year the PLRP family gets larger. One reason for this phenomenon is that the lake is a scientific goldmine. As we answer the first round of questions we came to the lake to research, so many new, interesting questions surface for us to ponder. And as we’ve set out to answer questions, we’ve had the chance to select the best technologies, methodologies and protocols to help us accomplish our science objectives. And what we’ve learnt isn’t just relevant to us at Pavilion Lake, but also has bearing on how humans will conduct science on the Moon, Mars and beyond. And with this natural procession of scientific research has come the development of a new crop of researchers. Allyson Brady, Rebekah Shepard, Alex Forrest, Ben Cowie, Margarita Marinova, Weston Pike, Olivia Chan, and Carol Turse are all graduate students who joined the project early on and who are all now either completed or on the cusp of completing their degrees. Through their work at Pavilion Lake, we’ve learnt so much about the physical, chemical and biological processes that govern this remarkable environment. And now we are in the process of shepherding in a new crop of students to evolve their research and tackle the new questions ahead of us. To me, all this is the essence of the scientific endeavor – gain knowledge, give knowledge, and grow knowledge.

This year we did 40 submersible flights in 10 days of operations. We cycled 9 scientist pilots (SPs) through a variety of rigorous sub flight plans that included contour mapping, detailed imaging, basin transects and deep sample collection activities. We gathered ground-breaking quantitative data to measure the efficiency, productivity, and discovery mindedness of each SP. We implemented a new Surface Data System (SDS) and communications plan that allowed us to view sub tracks and science notes in real time, and get voices from the deep up to the shore and into our Mobile Mission Control Center, or “The Hab[itat]“, much to the delight of an eagerly awaiting Science Backroom Team (SBT). We had underwater fluorometer experiments, water monitoring, and virology surveys taking place at the same time as the sub ops, as well as a very busy Education and Public Outreach schedule. Visitors came, visitors went, and there were a lot of boat trips to carry out everything we had to do to complete the science goals and objectives we set for the team and then some! It all got accomplished and happily, everyone made it home safely. Whew.

As a final note to all those who have been following our field season blogs, we’re planning on keeping our updates coming to you throughout the year, so definitely stay tuned. But for now, I just wanted to say thanks to all those who have been reading our entries, and by extension supporting our research efforts through the July 2009 field season. I’m looking forward to seeing the PLRP family again in 2010 and to meeting the new faces who will help to grow and evolve the project. Which leaves me to wonder what Donnie and Dana would have to say about having two camp cooks? Ah, but that’s a story for another time…

So long for now,

Darlene

Welcome to the Pavilion Lake Research Project

Posted on March 15th, 2009 by Darlene Lim

Welcome and thank you for visiting the Pavilion Lake Research Project’s (PLRP) new website.  We have many exciting activities upon us, and we look forward to sharing them with you as they unfold.  We’ve built a web space that reflects the values and guiding principles of our project.  It is here that we will be posting science reports, blogs, pictorials and videos that capture the science and exploration of our project.  We’ll be commencing our 2009 field season in July, but in the mean time, browse our site for a historical tour of our project’s work, and meet the dedicated and diverse individuals who make up the science and exploration team.  

Why is Pavilion Lake the focus of so much work?  The answer is: Microbialites! (cue the ‘tah dah’ music!) The lake is full of them, and we’re interested in knowing why they seem to be concentrated and thriving in this particular environment.  We also want to know how they are being made, and most of all if Life (microbial life that is) is involved in their construction, and if so, why? So many questions…that’s science for you!

To answer these questions, our team has spent hours in the water, studying it from the surface to its deepest (and coldest and darkest) depths. It has been a joy every step of the way.  To scientifically explore the lake we’ve done so using all sorts of aquatic tools: Remotely Operated Vehicles, SONAR, and SCUBA diving just to name a few. Included in this list since 2008 are Deepworker submersibles – single person subs capable of diving to depths of 600 m (2000 ft).  One of the PLRP’s goals has been to map the lateral and vertical extent and variability of the microbialites in Pavilion Lake. As well, we’ve wanted to understand these characteristics as they relate to environmental influences in the lake such as bathymetry, slope angles, sedimentation rates and ground water inputs. In 2004, we started doing this mapping with divers, but it rapidly became apparent that we needed a better and safer way to cover the size (6km long x 1km wide) and depth (65 m) of the lake. Here’s where the DeepWorkers come in.  Since humans in DeepWorkers are not subject to the intense pressures of SCUBA diving, we could send scientists and explorers underwater to safely and efficiently map the lake for hours on end. All while munching on cookies provided by our fabulous cook! As a result of the 2008 DeepWorker efforts, we have a contextual understanding of the environmental drivers behind the distribution and variability of the microbialites in Pavilion Lake.  Not to mention a comprehensive map of the lake that is coming together as I write this.  

So this is all very cool stuff scientifically, but as you read this you might still be wondering why the Canadian Space Agency and NASA (our main sponsors) are so interested in our lake activities.  The reasons are two fold: (1) the science has astrobiological relevance to the search for life on other planets, and (2) the underwater science and exploration activities are directly relevant to how we will explore the Moon and Mars with humans.  When it comes to the second reason, we can tell you that the physical, mental and operational rigors associated with the SCUBA diving and DeepWorker operations at Pavilion Lake are very similar to astronaut extra-vehicular activity (EVA) scenarios using spacesuits and pressurized rovers. Underwater, humans must, as they do in space, contend with limited connection to colleagues, protection/isolation from the environment, and life support systems (LSS), all while exploring and conducting science in variable and unfamiliar terrains.  Our project also gives astronauts a place to practice being a real field scientist before putting their boots on the Moon or Mars.  This is why since 2008, and for the foreseeable future, we’ll be integrating astronauts into our field team. From start to finish, the astronauts are as much a part of the science and exploration at Pavilion Lake as the researchers and graduate students. This preparation will mean that no matter which astronaut goes to the Moon or Mars, there will be some really great field science that will get done when humanity gets there.  Can’t wait!

As a final note, I want to say that our project emphasizes Safety, Environmental Stewardship, Science and Exploration, and what makes this all possible is teamwork. Everyone is involved in the science and exploration, and everyone contributes a unique viewpoint and important expertise.   We hope these values are expressed through everything we do, including our new web site. 

Thank you for your interest in our project.
