Postcards from The Field

Back To The Field Hello From The Methane

Back to the Field!

Hello from the Methane Emissions Technology Evaluation Center (METEC) ( at Colorado State University (CSU) in Ft Collins! I’m Navodi Jayarathne, a PhD student in Kate Smits research group (  at The University of Texas at Arlington (UTA). As part of multiple interdisciplinary projects funded by the Department of Transportation, Energy and the Northeast Gas Association the CSU/UTA Methane Migration team is running a three-month series of natural gas experiments aimed at finding solutions for underground natural gas leakage related challenges. The METEC pipeline experimental testbed is equipped with environmental sensors to make shallow subsurface, near surface, and atmospheric natural gas (NG) measurements. The on-going integrated experiment series was designed to address multiple underground NG leakage related questions including the expansion of gas plumes based on soil and atmospheric conditions, the formation of preferential pathways and to evaluate the existing and emerging leak detection and quantification (LDAQ) solutions for underground NG leaks. Nothing like being out in the field in the beautiful Colorado summer!

Hello Agu Community My Name Is Kyle Turner And

Hello AGU Community!

My name is Kyle Turner and I’m a Research Associate in Dr. Maria Tzortziou’s Bio-Optics Lab at the City College of New York ( As part of multiple interdisciplinary research projects funded by NASA, NSF, and NY Sea Grant, we have been busy collecting data in Long Island Sound and surrounding tributaries to better quantify the impacts of human and environmental pressures on the ecology and biogeochemistry of tightly interconnected urban-wetland-estuary systems. In particular, we are interested in linking these ecosystem changes to optics in order to develop more accurate algorithms for quantifying concentrations and fluxes of carbon across the land-ocean continuum from satellite remote sensing platforms. In this picture, my colleague, Brice Grunert, and I are collecting coincident measurements of water bio-optical properties in the Hudson River, NY. Nothing like kayaking on a nice sunny day for science! We wish you all fun and success in your future field adventures.

Hello Agu Community My Name Is Andrea Nicolau

Hello AGU community,

My name is Andrea Nicolau and I’m a Research Associate with the Earth System Science Center of the University of Alabama in Huntsville, where I also serve as the Regional Science Associate for the Mekong region for NASA’s SERVIR Science Coordination Office. This is a photo from a pre-COVID field work we did in a mangrove forest in Guyana, January 2020. This work was part of the SERVIR-Amazonia workshop in collaboration with Guyana government agencies and NGOs, and NASA Subject Matter Expert, Dr. Marc Simard (NASA/JPL), on the use of SAR data for monitoring mangroves. We did lose a few pairs of shoes in the mud after this picture was taken :)

Best wishes,

Andrea (Twitter: @puzzinicolau, @SERVIRGlobal)

Top Of The Day Agu Fans Taking You To The High

Top of the day AGU fans!

Taking you to the high Canadian Arctic are Anna Grau Galofre (Twitter: @agraugal - Arizona State University Exploration Postdoc) and Shannon Hibbard (Twitter: @Shann0nMars - Western University PhD Candidate). Anna and Shannon are riding off into the sun on their fat tire bikes to dig some baseline trenches across ice-wedge polygon troughs located on the eastern side of Axel Heiberg Island, NU, Canada. Anna and Shannon are geophysicists who use Arctic landscapes as analog environments for places like Mars. Together the two have spent 6 field seasons in the high Canadian Arctic pursuing their research on topics like distinguishing subglacial channels from fluvial ones, and what is the so called “brain” terrain. The trip was led by Gordon Oz Osinski (Twitter: @drcrater - Western University Director of the Institute for Earth and Space Exploration) and A. Mark Jellinek (University of British Columbia), also joined by Antero Kukko (Twitter: @KukkoAntero), Chimira Andres (@RocksNRockets) and Etienne Godin. Enjoy!

Dear Agu Community Hello From Our Pre Covid

Dear AGU community,

Hello from our pre-COVID field work from 2019! My name is Emil Cherrington, and I’m a Research Scientist with the Earth System Science Center at the University of Alabama in Huntsville (UAH). For our first Postcard from the Field, we wanted to share with you a collage of photos and other images related to our ongoing NASA-funded “Climate-influenced Nutrient Flows and Threats to the Biodiversity of the Belize Barrier Reef Reserve System” (BZ-SDG) project. In a nutshell, our project involves collaborating with stakeholders in Belize to use satellite data - calibrated using field observations - to monitor the country’s coastal and marine water quality, hence the pictures of water. This work is in support of the Government of Belize's Sustainable Development Goal (SDG) commitments, particularly regarding SDG 14 (“life below water”). Our project is one of a suite of projects that NASA is supporting in the framework of the Group on Earth Observations (GEO)‘s Earth Observations for the Sustainable Development Goals (EO4SDG) initiative.

Hamelin Pool Stromatolites Shark Bay Western

Hamelin Pool Stromatolites, Shark Bay, Western Australia against a sunset over the Indian Ocean. Stromatolites like those at Shark Bay represent modern analogues for ancient stromatolites (approximately 3.5 billion years old) that represent some of the earliest evidence for life on Earth.

Sending Holiday Wishes From The Kuruman Banded

Sending holiday wishes from the Kuruman banded iron formation in the Griqualand West Basin, South Africa. This photo was taken during my time as a field demonstrator for a Geology undergraduate class (I can never say no to a good field trip🙂). Loving the view from here and I hope you do too!

Buoy Completes A Decade Of Lake Observing Science

Buoy completes a decade of lake observing science

Dear Everyone:

The Muskegon Lake Observatory buoy (MLO; completed a decade of time-series weather and water quality data acquisition in this Great Lakes estuary in 2020 – delayed, but not defeated by the ongoing pandemic. Muskegon Lake is a model urbanized Great Lakes estuary that is impacted by legacy eutrophication, harmful algal blooms, and bottom water hypoxia, and the MLO serves as a sentinel that monitors water quality improvements during ongoing ecosystem restoration. Here, we are on board NOAA­–Great Lakes Environmental Research Laboratory’s R/V 5501 (buoy tender) retrieving the buoy from the lake after its 10th year of operation, assisted by NOAA crew members Beau Breymer, Todd Roetman, and Dan Burlingame. MLO continues to provide valuable long-term, time-series, open-access data (~10 million as of today) on estuarine ecology in the Great Lakes, allowing us to share observations and discoveries that have relevance to natural waters in inland and coastal zones everywhere that are similarly affected by anthropogenic forces and climate change.
