Bathymetric map of the Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) site
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 ๐

๐New 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."

Figure 1 from the paper, showing four subplots of maps of the west Antarctic shelf extending from the West Antarctic Peninsula to the Ross Sea. Figure caption: January 10-yr (2010โ2019) mean (a) OBPG/L2gen Chl a (which shows low Chl near the coastline), (b) OBPG nFLH (which shows elevated nFLH near the coastline), (c) OC-CCI Chl a (which also shows high Chl near the coast, agreeing with the pattern in the nFLH), and (d) difference in Chl a products OC-CCI Chl a minus OBPG/L2gen Chl a, over the west Antarctic shelf (which shows a band of much higher Chl, ~5-10 ug/L, extending along the entire west Antarctic coastline).
๐ 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.
I also spotted this on my walk today, so if I ever get homesick for South Africa I can treat myself
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 meltwaterโs impact on the carbon cycle, supported by Augmentum. ๐ง๐๐

๐ Iโm 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...
Chlorophyll data are from the European Space Agency ocean-colour climate change initiative project (OC-CCI) product. a, Map showing decadal chl-a trends (Sen slope; Methods) during summer. b, Monthly-mean chl-a anomalies during summer. c, Annual-mean chl-a anomalies. The red lines in b and c represent the trends calculated using the locally estimated scatterplot smoothing (LOESS) approach.
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. ๐งช๐

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.
The circumpolar Southern Ocean circulation seems to have tipped and is in transition to a new state. Not good. ๐๐งช

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 Iโve ever made.
