❄️ In a new collaborative study, WHOI scientists found that bacteria riding on “marine snow” can break down the minerals that help it sink. That means less carbon may reach long-term storage in the deep ocean.

Air‐Sea Gas Exchange in the Coastal Baltic Sea: Implications for Marine Carbon Dioxide Removal Gas transfer velocities (k) in the coastal Baltic Sea are lower than in other ocean regions at the same wind speeds The lower k is attributed to wind fetch limitation, wind-wave interactions, and...

We paid thousands of dollars to make this open access for you to enjoy.

Knowing the rate of air-sea gas exchange is critical for assessing the efficiency of marine CO₂ removal (mCDR). We assume we know this rate, but we really don't in coastal areas where mCDR is likely to be deployed. 🌊🧪

Unexpected climate feedback links Antarctic ice sheet with reduced carbon uptake A study in Nature Geoscience reveals that changes in the West Antarctic Ice Sheet (WAIS) closely tracked marine algae growth in the Southern Ocean over previous glacial cycles, but not in the way scientists expected.

New findings indicate that as the West Antarctic Ice Sheet shrinks, less bioavailable iron from icebergs may limit algae growth and reduce carbon uptake in the Southern Ocean. doi.org/hbnfpw

Fertilisation of the ocean with mineral dust promotes algal blooms that capture carbon, but when the same thing happens in Greenland, it reduces albedo leading to accelerating melting.

A new study analysed dust collected from the Greenland Ice sheet and found minerals essential to algal growth.

Coral Diversity Drops as Ocean Acidifies - Eos As seawater becomes steadily more acidic, complex branching corals die off and are replaced with hard boulder corals and algae.

"The ocean is the world’s largest carbon sink. As atmospheric CO2 [rises], the ocean absorbs more ... carbon, which makes seawater more acidic. [Researchers] have [recorded] falling marine pH levels disturb delicate marine ecosystems, like coral reefs, around the world." 🌎🧪
