Fragile treasure: Q&A with expert Alemu Gonsamo on the Hudson and James Bay peatlands Momentum is building to develop the Ring of Fire, which overlaps with one of the most important carbon storage systems in the world.

The Hudson and James Bay peatlands are among the most significant carbon storages in the world. With wildfires burning and a warming climate, @alemugonsamo.bsky.social explains why they matter and what’s at stake.

Peat depth and carbon storage of the Hudson Bay Lowlands, Canada This dataset contains ground-measured peat depth and maps with the spatial distribution of peat depth, carbon stock and uncertainty in the Hudson B...

The coastal shallow areas that are masked, including in northeast are 10s of metres, in some cases 100s of metres from shoreline, so after removing those, the shape of the shoreline seems the same. But it is not. Here are the maps: doi.org/10.5683/SP3/...

Areas with <40cm estimated peat depth were removed from the map. These are mostly coastal but also in many places in land.

Peat Depth and Carbon Storage of the Hudson Bay Lowlands, Canada We use stacking, an ensemble learning technique designed to mitigate overfitting, to estimate peat depth in the Hudson Bay Lowlands (HBL) The average peat depth of HBL is 184 (Β±48)Β cm with 90% of...

Our open access paper, Peat Depth and Carbon Storage of the Hudson Bay Lowlands, Canada, is online now in Geophysical Research Letters. We implement creative ensemble learning approach on multiple models to minimize overfitting & improve generalization agupubs.onlinelibrary.wiley.com/doi/full/10....
