We hope a deeper understanding of climate change impacts can improve the effective management of salt marshes for blue carbon. So, is sea-level rise a major driver of blue carbon accumulation & storage in salt marshes around the world? Stay tuned... [4/4] #ACCEConf20 #ACCE_Geo

To test this hypothesis, we are comparing detailed sea level reconstructions to high-resolution carbon accumulation rates using sediment cores collected from salt marsh sites around the world. As SLR varies geographically, a global perspective is key! [3/4] #ACCEConf20 #ACCE_Geo

Rising sea levels wash more sediment over the marsh surface, building thick layers of carbon rich material. The creation of vertical space for sediment to build gives rise to the hypothesis that sea-level rise (SLR) can ENHANCE blue carbon accumulation [2/4] #ACCEConf20 #ACCE_Geo

Salt marshes, through the capture & storage of vast amounts of #bluecarbon in their sediment, are one example of #naturebasedsolutions to #climatechange, but how does #sealevelrise affect their capacity for carbon accumulation? 🌱🌊 [1/4] #ACCEConf20 #ACCE_Geo

Finally, two talks in #ACCE_Geo: @_LucyMcMahon on whether sea-level rise can enhance blue carbon accumulation in salt marshes and @Lauren_Rawlins1 on the evolution of supraglacial channels on the Greenland ice sheet

4/4 #ACCEconf20 #ACCE_Geo 1⃣ without labile plant carbon microbes could switch to eating recalcitrant soil carbon. 2⃣ no plant competition could mean more N + P for microbes🦠 3⃣New soil conditions ➡️ new microbial community structure🍄🦠 4⃣ reduced soil respiration

3/4 #ACCEconf20 #ACCE_Geo We don’t know yet! COVID cancelled my field season this year 🥺. But current literature📚📖 can identify possible effects…

2/4 #ACCEconf20 #ACCE_Geo Sudden plant death stops 🚫 the plant uptake of CO2🌿, and the transfer of C to the soil through roots. How does this effect carbon cycling🔁 in Arctic soils? Could undecomposed arctic soil carbon be at risk of release?😬⚠️

1/4 #ACCEconf20 #ACCE_Geo For over half a century the Arctic has been greening 🟩. Trend climate change📈 boosted plant growth🌎. Now extreme events are causing plant death 🍂🥀and driving arctic browning 🟫 #climatechange

3/ #ACCEconf20 #ACCE_Geo We use dating techniques such as #radiocarbon, #210Pb, and #pollen to create a #chronology. Combining these, the transfer function model, and some more stats*, we can generate sea-level reconstructions. *too many stats, too little characters!

2/ #ACCEconf20 #ACCE_Geo We collect samples of modern #salt-#marsh #foraminifera to use in a regression model to predict the heights of #fossil forams i.e. the palaeomarsh surface. Rising sea level created this #stratigraphy, with a silt/clay layer overlain by a salt-marsh peat.

1/ #ACCEconf20 #ACCE_Geo #Australia is an area of importance for quantifying mass loss from N Hemisphere ice. Distribution of meltwater means that low and mid-latitudes in the opposite hemisphere experience the greatest rises. Can we see 20th C #Greenland loss in Aussie records?

#ACCEconf20 #ACCE_Geo If photosynthetic microbial communities do change with degradation (and restoration), then they may have potential as bioindicators. Large areas of UK peatlands are currently being restored: these ‘jewels of the bog’ could be a valuable tool! 4/4

#ACCEconf20 #ACCE_Geo Responses of peatland photosynthetic microbes to disturbances are less well understood. Their functional roles in the peatland microbial community and carbon cycling (they photosynthesise after all) are also unknown. That’s what I’m trying to find out! 3/4

#ACCEconf20 #ACCE_Geo Photosynthetic microbes (eukaryotic microalgae, and cyanobacteria) are abundant and diverse in many UK peatlands. Their communities can vary at a small spatial resolution between the raised moss hummocks and small pools within the same site. 2/4

#ACCEconf20 #ACCE_Geo Peatlands are important ecosystems, capable of storing huge amounts of carbon and providing many other ecosystem services. Unfortunately, they are widely threatened by land use changes, pollution and climate change. 1/4
