Expansion of macroalgae forests and gains in Blue Carbon at Caleta Potter, Antarctica
In the western Antarctic Peninsula, glacier systems have retreated as a result of a temperature increase of approximately 2°C over the past 50 years. This process has led to the formation of “new ice-free areas” (NALH) which are suitable for the colonization of benthic marine algae, as observed in t...
