Whilst trace metals influence ocean productivity, there are a paucity of regions where their spatial and temporal variability are well explored. Ortega et al., investigate the drivers of trace metal dynamics in the productive Northern Gulf of Alaska 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

🌊New paper out using 7Be to constrain global atmospheric deposition. "aerosol processes are more dynamic than previously estimated, with important implications for...aerosol-driven climate effects and marine biogeochemical processes globally." In memory of David Kadko. rdcu.be/eHihM

🌊 I have a new paper out in L&O Letters! We show that ocean color-based estimates of chlorophyll concentrations within 100 km of the Antarctic coastline are severely underestimated when applying the standard NASA L2gen atmospheric processing. This is caused by adjacency effects from ice and snow.

Excited to start my new position at the @noc.ac.uk today. Feels like coming home to where my academic career began

Researchers from the NOC have begun ground-breaking Arctic fieldwork in the fjords around Greenland to understand glacial meltwater’s impact on the carbon cycle, supported by Augmentum. 🧊🔁🌊 Read more here ➡️https://noc.ac.uk/news/noc-partners-augmentum-support-arctic-mission

🌊 I’m hiring! Last few days to apply!! Research Scientist in Marine Ecology & Machine Learning at the National Oceanography Centre, Southampton (UK). Got experience with machine learning techniques applied to marine ecology, biogeochemistry or climate change? careers.noc.ac.uk/vacancy/rese...

Phytoplankton are microscopic plants living in the water column. They flourish around Antarctica, where they both remove carbon from the atmosphere and are the base of the food web. Over the last 25 years, they have changed, and it's related to ice lose. 🧪🌊 Link: www.nature.com/articles/s41...

Today I had my farewell drinks at SOCCO. My 2 year postdoc position that turned into a beautiful 10 year adventure. From September I will be starting my new position @noc.ac.uk as a Senior Researcher in the Ocean BioGeoSciences group.

🌊 New paper led by @sarahnicholson.bsky.social, myself and others. We generated a multi-year, multi-algorithm data product of global phytoplankton bloom phenology. The data is provided at 3 different spatial resolutions depending upon your study requirements. essd.copernicus.org/articles/17/...

10 years ago today I landed in Cape Town for a 2 year postdoc position. Countless memories, 3 job promotions and 1 husband later I would say accepting this position was one of the best decisions I’ve ever made.

🌊 interesting article on the status of polar research in South Africa. Here’s hoping something will finally be done to fix the many issues. www.dailymaverick.co.za/article/2025...

🌊 SOCCO’s brand new website is finally live. socco.org.za Check it out to find out more details about the team and the research projects we are involved in.

🌊 Today I presented at #icshmo2025 on some recent work I have been doing with @altagliabue.bsky.social and others. Where we performed a systematic assessment of NPP trends in models and observations, whilst also highlighting critical knowledge gaps that represent future research priorities.

As autumn creeps in another chilli harvest has come to an end. Proud of my green thumb this year in getting ghost chillies to grow.

Spent the long weekend camping in the mountains and disconnecting from the world.

First ever Christmas just me and my fiancé alone! And what a lovely Christmas it is turning out to be 🎄

A paper in Nature reports that recent record lows in Antarctic sea-ice extent have led to increases in the frequency of storms over the newly ice-free ocean. https://go.nature.com/41I6PwC 🧪

An awesome day was had celebrating our end of year function at Silvermine dam. We had a very successful year at SOCCO, and now it’s time for a nice break.

Today we are saying goodbye to Antoine Ringarde who has been visiting me from France for the past 2 months. A very productive visit where we got to properly interrogate trace metal cycling and phytoplankton quota data generated from the SWINGS cruise

It was time to migrate over from the bad place
