Study - how marine heatwaves are reshaping the shape & carbon content of #phytoplankton in NE Pacific. Elongated cells dominate during warming, likely altering the carbon pump. Long-term #CPRsurvey data is critical to understanding #climatechange impacts at microbial scales. doi.org/10.1002/lno....

You can spend a life time on a boat - and still be looking at new things every single day! Here is a quick glimpse of what’s just under our feet/boat!!

Fig 1: Central panel showing biomes used for this study (see Table 1 for details): North Atlantic subpolar seasonally stratified (NA-SPSS), North Pacific subpolar seasonally stratified (NP-SPSS), Northern Hemisphere subtropical seasonally stratified (NH-STSS), Northern Hemisphere subtropical permanently stratified (NH-STPS), Southern Hemisphere subtropical permanently stratified (SH-STPS), and Southern Hemisphere seasonally stratified, incorporating the subpolar and subtropical components (SH-SS). Surrounding panels show time series plots of biome-integrated sea-air CO2 fluxes (annual maximum and minimum values irrespective of the month of occurrence). pCO2 products (blue) and GOBMs (green) are shown for both the ensemble mean (bold) and for one standard deviation (shaded). Positive (negative) values indicate outgassing (ingassing) of CO2. The regions in white in the central panel are not included in this analysis, in each panel, winter is designated by W, and summer by S, in order to distinguish the seasonal phasing between the subtropical and subpolar/Southern Ocean biomes.

Keith Rodgers and too many co-authors to mention present a synthesis of the seasonal variability of the global surface ocean carbon cycle.

I'd like to introduce a new page on my website: U.S. climate indicator visuals (zacklabe.com/united-state...).

I only have a few basic variables so far, but I will be expanding this summer to add a range of metrics (e.g., ecological). I welcome suggestions! Hope this is useful, especially nowadays.

The #GlobalTippingPoints2025 conference has started! Over 500 scientists are discussing the latest science on Earth System risks here in Exeter.

It’s Monday and time for a Calanoid copepod cheer! (Sound on!) This little juvenile is reminding you YOU’VE GOT THIS! And that together, we can achieve amazing things!

See, the ecosystem services of plankton go beyond nutrient cycling, they can be little motivators too! #plankton 🦑

Last month's total #Arctic sea ice volume averaged the 2nd lowest on record for the month of May. This was about 38% below 1979 levels and 24% below the 1979-2024 May average.

Important to note that our conclusions depend not just on the results of model integrations, but on our understanding of the mechanisms involved. Still, little is certain in this business, and it does not mean the risk of collapse is not there, even if we think it is unlikely.

‘Women are the best to women’: has Iceland found the antidote to toxic ‘girlboss’ feminism? Fifty years ago, Icelandic women went on strike, kickstarting a gender revolution. Today, the concept of ‘konur eru konum bestar’ is everywhere – including the female-led coalition government

So well deserved 👏 watch this space for some top phytoplankton science 🧪

A map of the world in the Spilhaus projection with the global ocean as the main focus. It includes arrows of the global currents overlaid onto sea surface temperature & velocity. Spilhaus is a projection that emphasizes the interconnectedness of the world's oceans. The map features a centered and enlarged southern ocean that is surrounded by land masses, creating a continuous east-west expanse of ocean around the world.
