**After joining SystemCO2, please feel free to introduce yourself and your interest in the marine carbonate system by replying to this thread!** * * * I’m Matthew Humphreys, a scientist at the [NIOZ Royal Netherlands Institute for Sea Research](https://www.nioz.nl/en) on the island of Texel. I started using CO2SYS-MATLAB during my PhD in Southampton back in the early 2010s before transitioning to Python and creating [PyCO2SYS](https://pyco2sys.readthedocs.io/en/latest/) originally in 2020 (plus [CO2System.jl](https://github.com/mvdh7/CO2System.jl) for Julia at around the same time). These days, I continue to develop PyCO2SYS and some other related Python packages alongside various other projects. ---

Hello! I’m Jon Sharp, a scientist at the [University of Washington Cooperative Institute for Climate, Ocean, and Ecosystem Studies](https://cicoes.uw.edu) in Seattle. I started using CO2SYS-MATLAB during my PhD at the University of South Florida while working on a method to measure carbonate ion concentration, and extended the software to accept [CO₃²⁻] as an input in 2019. I still maintain [that version of CO2SYS-MATLAB](https://github.com/jonathansharp/CO2-System-Extd) today. ---

I’m Daniel Sandborn, and I work on CO2 and transient tracer dynamics as a postdoc at the University of Washington. I’m a contributor to PyCO2SYS, as well as to other ocean carbon packages including TRACE, [TRACE-Python](https://github.com/d-sandborn/TRACE), and [PyESPER](https://github.com/LarissaMDias/PyESPER), which I hope to make more interoperable with marine carbonate system software. ---

Hello! I’m [Oscar Branson](https://biomin.esc.cam.ac.uk/). I work on biomineralisation at [Earth Sciences in Cambridge](https://www.esc.cam.ac.uk/), and am particularly interested in carbonate chemistry from that angle. Also have half a foot in palaeoceanography, and therefore carbonate system chemistry in seawater with unusual compositions. Starting to move towards Julia, and putting together a carbonate system calculator on there… I wrote a python carbon system calculator (cbsyst), put together an improved (i.e. faster) python implementation of the MyAMI model (pymyami) for empirically correcting Ks for palaeo seawater, and am a maintainer of KGen, which is designed to provide consistent-cross platform K values for palaeo (and modern) seawater. (Sorry no links for software - apparently I’m only allowed 2 urls!) ---

Hi my name is Lennart. I work on all things carbon. Traditionally plankton related but morerecently excited about benthic carbon and alkalinity fluxes. I also have some feelings for phosphorous, and on a good day for nickel. Currently focussing on research around carbon dioxide removal. ---

I am Jean-Pierre Gattuso, the original creator of the [seacarb](https://cran.r-project.org/web/packages/seacarb/index.html) R package, first released in 2007. Over the years, the project has benefited from the valuable contributions of many colleagues. Now retired and holding emeritus status, I am pleased to announce that James Orr has kindly agreed to succeed me as the maintainer and lead developer for future functions and improvements. ---

Hi all, I’m Luke Gregor, a data scientist at the [Swiss Data Science Center (ETH Zürich)](https://datascience.ch) and part-time oceanographer (20%) in [Nicolas Gruber’s group](https://up.ethz.ch). My work sits at the intersection of machine learning and ocean biogeochemistry, mostly reconstructing surface ocean fCO₂ and air-sea CO₂ fluxes from sparse observations. I end up using carbonate system calculations as a tool rather than studying them in depth, so I’m here more as an interested user than a CO₂-sys developer (though I did, once upon a time, contribute to the code base). Looking forward to following the discussion! ---

I’m Steve Jones, working at VLIZ in Ostend and data coordinator for ICOS Ocean Thematic Centre. I’m generally involved in surface ocean CO2 measurements. I write software for processing and QC of ocean data, and am involved with SOCAT, SOCONET and general surface ocean CO2 networks. I’m starting to explore processing data from pH and other related sensors, so while my work isn’t directly related to the group, I can certainly exist on the fringes… ---

Hi folks! Brendan Carter of CICOES at the University of Washington, working with NOAA PMEL.

My master’s at Dalhousie University focused on data quality of carbon system parameters for coastal ocean acidification and ocean alkalinity enhancement monitoring. I currently work as a Research Scientist at UW in the PMEL Carbon Group (Brendan is one of my groups PI’s!) ---

My name is Barham Gueye, and I am a first-year PhD student in a cotutelle program in marine biogeochemistry between Sorbonne University (LOCEAN laboratory) and Cheikh Anta Diop University of Dakar (Laboratory of Atmospheric and Ocean Physics, LPAO-SF). My research focuses on the carbonate system in the Canary Upwelling region, particularly the Senegal–Mauritania upwelling system. I am especially interested in the measurement and analysis of biogeochemical parameters such as total alkalinity, dissolved inorganic carbon (DIC), pH, and pCO₂. For my PhD work, I use the CO2SYS MATLAB toolbox. I am also interested in computing CO₂ air–sea fluxes in MATLAB, and I would appreciate any advice on this. In addition, I would like to know whether there are more recent or advanced versions of CO2SYS for MATLAB that you would recommend. ---

Hey everyone, I’m Elise Droste. I’m a Research Scientist at the National Oceanography Centre in Southampton (UK). I use PyCO2SYS in my research on the marine carbonate system of polar oceans and have lots of experience analysing DIC and TA on VINDTA instruments.

Hi, I’m Katelyn Schockman. I’m an Assistant Scientist at the University of Miami, working in collaboration with NOAA’s Atlantic Oceanographic and Meteorological Lab (AOML). I use the MATLAB version of CO2SYS regularly to make carbonate system calculations for a variety of datasets (NOAA OA cruises, GO-SHIP, AOML coastal cruises, etc.) and to help assess internal consistency of various datasets. I am very interested in the thermodynamics of the CO2 system in seawater as well as larger scale changes in the CO2 system around the globe.
