April 2022 – You can now find the UConn Gas Biogeochemistry Lab on Instagram @uconn.gbl! Follow along to watch us set up the lab and get started collecting data!

Cara had her first grant funded as PI! It is a seed grant from the Connecticut Institute for Resilience and Climate Adaptation (CIRCA) and the project will focus on characterizing the biogeochemical impacts of submerged aquatic vegetation such as eelgrass. We will be putting sensors in the water this summer!

March 2022 – Our manuscript “Interannual variability in methane and nitrous oxide concentrations and sea-air fluxes across the North American Arctic Ocean (2015–2019)” (Manning et al., 2022) has been accepted in Global Biogeochemical Cycles.

The author’s accepted manuscript is freely available on EarthArXiv

February 2022 – Procurement progress during a pandemic! The first order of lab equipment has arrived and our first mass spectrometer has been ordered with expected delivery in the summer.

January 2022 – Cara arrives at UConn! Check out this video showing the campus and research vessels, as well as our new lab and office space, which is ready to be filled up with new research.

November 2021 – Big news! I will be an Assistant Professor with the University of Connecticut Department of Marine Sciences starting January 1, 2022! I am excited to be setting up a laboratory where we will develop and apply mobile and laboratory-based methods to measure gases and other biogeochemical tracers.

I will be recruiting a graduate student to start in fall 2022. Please check out the student recruitment advertisement for more info (the application deadline is Jan 10, 2022).

I will have paid opportunities for undergraduate researchers beginning in summer 2022. 

My mantra until tenure will be “UConn do it!”

September 2021 – Our preprint “Interannual variability in methane and nitrous oxide concentrations and sea-air fluxes across the North American Arctic Ocean (2015–2019)” (Manning et al., 2021) is now available on EarthArXiv (where I serve as a content moderator)! This paper includes ~2000 measurements of methane and nitrous oxide from 13 research cruises and we use the results to characterize the distributions and fluxes of these gases and their variability in time in a rapidly-changing Arctic system. The figure here shows the station locations.

September 2021 – A new paper led by Kun Jia (who completed a MSc at UBC) is published! “Technical note: Effects of iron(II) on fluorescence properties of dissolved organic matter at circumneutral pH.” This paper characterizes how the presence of Fe(II) in groundwater impacts fluorescence spectra and is part of my foray into groundwater research that began during my postdoc.

June 2021 – A new paper led by newly-minted PhD Dr. Robert Izett is published, titled “ΔO2/N2′ as a new tracer of marine net community production: Application and evaluation in the Subarctic Northeast Pacific and Canadian Arctic Ocean.” The paper compares net community production estimates from ΔO2/N2′ (measured with an O2 sensor and a total gas pressure sensor and corrected for the different physical properties of O2 and N2) to estimates from the traditional ΔO2/Ar method (measured with a mass spectrometer). You can also check out Robert’s recent papers in L&O Methods and Oceanographythat describe the instrumentation and computational method for quantifying ΔO2/N2′.
