To celebrate the end of a successful semester, the lab headed to a local pottery studio where we all learned how to hand build bowls out of clay. We are all looking forward to what 2023 has in store!

Amber headed to San Marcos for a 3-day all-hands meeting with our NSF TERRG project. The goal of the meeting was to discuss data, analyses, and future papers. Overall, the meeting was a success. We met daily at Spring Lake Hall overlooking one of the many springs in San Marcos. We even were inspired by our breakfast waffles as we thought about stream ecosystems across the coastal plain Texas precipitation gradient.

NSF-funded REU student Kaitlyn Blankley from Eastern University (located in Pennsylvania) spent the summer at SHSU working on modeling dissolved oxygen data from Harmon Creek to estimate daily gross primary production and ecosystem respiration. Katie presented her work both as a talk and a poster along with her fellow REU students! Well done Katie!

Amber spent a week in Mexico working with Drs Mercedes Castillo (ECOSUR) and Krista Capps (UGA) and colleagues checking out several rivers where we are working on estimating ecosystem metabolism. These are all mid-size tropical rivers where work is done via boat. It was an amazing trip! We saw (and heard) monkeys, crocodiles, and even a Tapir!

March has started out great! Makayla and Katrina have been collecting leaf packs for Makayla's leaf decomposition experiment. We also captured a high flow event -- increased dissolved organic carbon and particulate organic matter - baby steps toward developing rating curves for our deployed sensors!

We (and our sensors) survived a week of cold and snow due to the polar vortex. While SHSU was closed and we were all home dealing with power and water issues, our sensors remained in the field collecting data.

First data download indicated that Harmon Creek got down to 0 degrees Celsius during the arctic blast!

We have been busy in the lab and field! Makayla has been working on getting her leaf decomposition study together - along with help from Katrina. Connor has been busy sampling Texas Coastal Streams and crunching metabolism data for our NSF funded TERRG project. And finally, we have deployed sensors out at our local field station to collect high-frequency data on dissolved oxygen, temperature, dissolved organic matter, turbidity, and conductivity. So far, so good! Excited to see what data may come!

Despite COVID we have been able to (safely) continue with our field work across our Texas Coastal Stream sites as Connor along with help from his friends and fellow graduate students at SHSU have been able to get out and keep up with our monthly sampling for our NSF funded TERRG project. Thank you Chelsea & Brittney!

Amber and Connor headed to Corpus Christi for the NSF funded TERRG kick-off meeting where the crews from SHSU, TAMU-Corpus Christi, and University of Florida could meet, discuss science, and check out our stream sites along the coastal precipitation gradient. It was a great productive, fun weekend! Field work officially starts in January.

Chris Patrick, J Derek Hogan (Texas A&M University Corpus Christi), and Matt Whiles (University of Florida) were awarded funding from the National Science Foundation to study the linkages between stream metabolism and higher trophic levels across the climate gradient of Texas coastal streams. The project, TERRG: Thresholds in ecosystem responses to rainfall gradients, will kick off this fall!
