📣NEW PAPER ALERT📣

Our mini-literature review "Monitoring low-oxygen-adapted subsurface phytoplankton distribution in a changing ocean" has been published in Frontiers in Marine Science today!

We used 33 years of data from the Bermuda Atlantic Time-series Study (BATS) 📊and highlight the implications for and importance of monitoring phytoplankton below the ocean surface. #ClimateChange #Phytoplankton #MarineScience

🚨 Excited to share paper out today in @NatureClimate 🎉 with co-authors @rjbrewin & @xuerong_sun from @uniexecges, we show surface & subsurface phytoplankton at the BATS site respond to climate variability differently. 🌊 @UniofExeter https://t.co/TGfiUljTzo

Is antibiotic-resistant bacteria in 🇬🇧rivers a threat to public health? 💧🦠💊

Over the summer at the @UniofExeter we have been investigating whether swimming in #sewage polluted rivers and lakes across the UK 🇬🇧 increases the risk of carrying antibiotic-resistant E. coli in our guts.

But non-swimmers can carry these bacteria, too.

If you do not swim in rivers, lakes or the sea, take part in the #PooSticksStudy and help us understand how widespread these bugs are among the British public and if swimming in rivers is linked to changes in the likelihood of harbouring these types of bugs.

Interested? Request your kit now: https://t.co/srjFlbxy4j

Please share! The more people take part, the more confidence we can have in our findings.

🚨New Review!

The Southern Ocean represents a substantial carbon sink.

Boyd et al. describe how expanding observations are providing increasing insight into the contribution of biota to the carbon cycle in the Southern Ocean
