Lots of excitement & updates for the Carey Lab!

Lots of great updates to share!

1) Jon has just returned from a week at the University of Wisconsin getting the GLM model calibrated for FCR; we are super close to getting the plankton succession up and running for our favorite reservoir!

2) Kate received a prize for her poster at the 2015 Biological Sciences Research Day- congrats!

3) Alex was chosen as the 2015 College of Science’s Outstanding Masters Student- woohoo!  This is a great honor and we’re super proud of all of her accomplishments.

4) Jon, Kate, and Cayelan took a road trip with the Stream Team’s eminent Dr. Jack Webster and spent some quality time helping Jack sample streams at Coweeta Hydrological Lab in mid-March.  We toured the Smokies on our way home and ate lots of barbecue.

5) The lab has three new papers out; check our website’s Publications page.

6) Cayelan just returned from the PRAGMA conference in Nara, Japan in early April and gave a talk with GRAPLE colleagues Renato Figueiredo, Ken Subratie, and Paul Hanson.  She enjoyed a lightning fast 48 hrs in Japan, especially the cherry blossoms.

7) Our field season is in full swing!  We’ve picked up our magic sensor from good colleague Dr. Francois Birgand at NC State and have successfully deployed it in FCR.

Francois, Cayelan, and Alex- we love the magic sensor! Photo credit to Bryan Maxwell, Birgand grad student extraordinaire.

We are doing *all* the science at the catwalk.

8) Perhaps most exciting, we are being joined by Ryan McClure, a new grad student in the Carey Lab.  Ryan is currently working on the Guppy Project in Trinidad and has several years of experience working in streams in Trinidad, Iceland, and at Montana State in Wyatt Cross’ lab.  We are super excited to have Ryan join us in June- more updates to come!

ASLO & Virginia Water Conference

It has been a busy winter in the Carey Lab: we’ve had sporadic field sampling while the reservoirs have been frozen (another dimictic year!), and a whole lot of travel. Cayelan co-organized the Reservoir Limnology session at the ASLO meeting in Granada in February, and the whole lab presented at the Virginia Water Conference in Richmond in March.


We covered almost the entire food web: Alex discussed internal vs. external nutrient loading in the reservoirs, and Kate and Jon gave a dual phytoplankton/zooplankton talk.  We are looking forward to getting the field season started in earnest April 1!

Lab retreat 2015

We have just returned from our second annual lab retreat- an overnight in the woods where we get caught up on each other’s upcoming fieldwork plans, discuss last summer’s data, and coordinate lab activities. This year we also talked a lot about the ‘science of team science’ and how our Myers-Briggs personalities influence our collaboration styles.

For the second consecutive year, it was the coldest night of the entire winter (-23oF, with windchill) and Alex thoroughly beat us (repeatedly) in rummikub.  Maybe next year it will be balmy warm and we’ll overcome Alex’s rummikub domination…

REU position available in the lab! Deadline 27 February 2015

Summer 2015 (May 24 – August 1, 2015)

Undergraduate Research Fellowships Announcement

National Science Foundation Research Experiences for Undergraduates (REU) Site at Virginia Tech


 Virginia Tech, Blacksburg, Virginia

 Application Deadline February 27, 2015 (5:00 PM, EST)

Applications are invited from qualified and motivated undergraduate students (rising sophomores, juniors and seniors) from all U.S. colleges/universities to participate in a 10-week (May 24-August 1, 2015) summer research in interdisciplinary water sciences and engineering at Virginia Tech. U.S. Citizens or Permanent Residents are eligible to apply. The research program is funded through the National Science Foundation – Research Experiences for Undergraduates (NSF REU) program. The 10-week internship will begin on May 24, 2015 (arrival day) at Virginia Tech and end on August 1, 2015 (departure day). The research internship includes a stipend of $450/week, housing (two persons per room), $400 for meal, and travel expenses (limited to a maximum of $500 per person).   We have already graduated 66 excellent undergraduate researchers representing 45+ institutions in the United States during 2007-09 and 2011-14. Application materials, details of Research Mentors along with summer 2015 research projects and other program activities are posted on the following website:


 Applicants are requested to upload their applications along with other required documents by the deadline (February 27, 2015, 5:00 pm, EST). Successful applicants will be informed by March 9, 2015.  Please contact Dr. Vinod K Lohani (phone: (540)231-9545; FAX: (540) 231-6903; E-mail: vlohani@vt.edu) for questions.

Carey Lab at GLEON 16 conference

Cayelan, Alex, Jon, and Kate recently returned from the GLEON 16 conference in Orford, Quebec after an awesome week!  The lab enjoyed some serious quality bonding time after embarking on an 18-hour road trip from Blacksburg to Canada and 17 hours back, with many thanks to Kate and Kaitlyn Doubek for packing us snacks en route.  At G16, everyone presented a poster and gave working group talks/report-backs, resulting in a phenomenal but very intense week.  We are all looking forward to some time off to come down from our post-G16 euphoria 🙂


Recent press for GLEON-PRAGMA and Gloeo gang collaborations

Two recent stories have emerged in the press about Carey Lab collaborative efforts:

1) The GLEON blog has highlighted Cayelan and Jon’s role in the joint GLEON-PRAGMA expedition to study lake eutrophication using high-performance computing and virtual overlay networks with collaborators Paul Hanson (University of Wisconsin) and Renato Figueiredo (University of Florida).  Read more here.

2) Second, Cayelan’s recent paper in Freshwater Science was highlighted as the Feature Article of the issue, and Society of Freshwater Science newsletter editor Deb Finn wrote up a very nice article on the background story of the Gloeo gang collaboration with Kathy Cottingham (Dartmouth), Kathleen Weathers (Cary Institute of Ecosystem Studies), and Holly Ewing and Meredith Greer (Bates). Read more here (scroll down until “Freshwater Science Article Spotlight”).

Alex’s first paper is in press, and Jon has been invited to be part of the GLEON Fellowship Program!

Two exciting updates for the Carey Lab:

1) Alex’s first paper, which provides proof-of-concept data on the successful oxygenation of Falling Creek Reservoir (Roanoke, VA), is in press here at Water Research.  In this paper, Alex, Rick Browne (Carey Lab alum, M.S. 2013), Paul Gantzer, Mark Mobley, John Little, and Cayelan analyzed the effects of side-stream supersaturation hypolimnetic oxygenation on the physics and nutrient cycling of FCR during intermittent periods when the oxygen was on vs. off.  We observed that the system was able to successfully increase oxygen concentrations at depth while maintaining thermal structure, which in turn prevented Fe and Mn release from the sediments.

2) Jon has been invited to be a GLEON Fellow!  The GLEON Fellowship Program trains small cohorts of graduate students from around the world to analyze large and diverse data sets, operate effectively in diverse international teams, and communicate science to researchers, the public, and managers.  As a GLEON Fellow, Jon will take part in three international workshops over the next 1.5 years while completing an interdisciplinary, collaborative scientific project.  More information on the GLEON Fellowship Program can be found here.

Carey Lab featured in the VT football halftime video!

Every fall, the public relations office for Virginia Tech puts together a 30 second video highlighting the best of Virginia Tech to air as part of the football halftime show- and we have just been notified that our lab is featured in this year’s video!  Grad student Alex Gerling sampled Falling Creek Reservoir in Roanoke on camera, and there is some nice underwater footage of our CTD profiler.

To see the proper 30 second clip, go here.  FCR & Alex are about 17 seconds in.

To watch the video being aired at the William & Mary football game at Lane Stadium in front of 62,722 people, see:  VirginiaTechHalfTimeVideo_William&MaryGame  (forgive us for the screams halfway through; we were very excited!)
