Current group members
Dr Matthew P. Humphreys
Tenure-track scientist at NIOZ Texel in the Department of Ocean Systems (OCS) since November 2019. Interested in the changing biogeochemistry of the modern ocean, with a focus on CO2. Conducts ocean-going, observation-based research alongside theoretical studies of the marine carbonate system and develops related scientific software. Previously based in the UK at the universities of Cambridge (undergrad), Southampton (PhD and postdoc), and East Anglia (postdoc).

Louise Delaigue
PhD student at NIOZ Texel in the Department of Ocean Systems (OCS) since February 2020. My project explores blindspots in the marine carbon cycle with a focus on how the ocean responds to increasing anthropogenic CO2 emissions, especially in under-sampled regions such as the southern Indian and Pacific Oceans. I use scientific programming to investigate new measurements in combination with already existing datasets. MSc from McGill University (Canada).

Yasmina Ourradi
PhD student at NIOZ Texel in the Department of Ocean Systems (OCS) since August 2021. My research project aims at exploring and better understanding the human impact, especially infrastructure development such as offshore wind farms, on the carbonate system (mainly the pH) in the North Sea. The project is carried out through a combination of laboratory studies and high-resolution autonomous CO2 system sensors that will be deployed in the Sea. MSc from the Mediterranean Institute of Oceanography (France).

Ben Cala
PhD student at NIOZ (Texel) and Utrecht University since February 2022. After jumping from organometallic and computational chemistry during my BSc at the University of Tübingen (Germany) to atmospheric chemistry at Cambridge University (UK), I now ended up in chemical oceanography. I am interested in the dissolution of calcium carbonate in the water column. Specifically, my project aims to identify drivers of dissolution apart from the saturation state, through field and lab experiments as well as modelling approaches.

Simen Bootsma
I am Simen, an Applied Physics master student from the University of Twente. During my six-month internship at NIOZ, I will investigate marine alkalinity using the Water Mass Transformation Framework, thus combining the areas of expertise of my supervisors Matthew Humphreys and Sjoerd Groeskamp. Initially, we will focus on global alkalinity budgets and shift to local scales when time permits.
Job Thijssen
Masters student from the VU Amsterdam studying CO2 system changes around methane seeps in the North Sea.
Anne Roozendaal
Masters student from Utrecht University studying anthropogenic CO2 uptake in the South Atlantic Ocean.
