For decades, these areas have been largely outside the scope of international governance, despite playing a central role in #climateregulation, #biogeochemicalcycles, and the integrity of #marineecosystems.

Station Papa, about 1200km downwind from the Copper River dust plume, has a number of instruments to monitor biological activity year round, so it would a be a nice exercise to explore monitor its data in the context of these dust events.

more than a week long of almost continuous injection of #highlatitudedust well into the GoA.

Something to keep in mind when doing nutrient budgets in the
area.

And the just arrived image from NOAA20 just arrived and confirms continued (already a few days like this) #highlatitudedust activity particularly from the Copper River Delta.

Based on observations, Siqi Wu et al. found that #LitterMassLoss was decreased by 4.5%, and #C and #N release were significantly reduced by 6.7% and 3.4%, respectively, under #ElevatedCO2 in #TerrestrialEcosystems, which meant that may lead to negative #BiogeochemicalCycles.

#fires in southern Chile yesterday bring abundant smoke over the SE Pacific, an area that tends to be depleted of nutrients at this time of the year, a deficiency that it is often compensated by nutrients contained in the deposited smoke.

#ICYMI

For a few weeks, there have been some pretty intense fires in Tasmania.

Although the smoke is difficult to see from space, it is being moved into higher latitudes by the perpetual polar lows.

#highlatitudedust and #biomassburning activity yesterday in the south end of #Argentina.

Both dust and smoke make up a haze that extends almost 1000km are traveling into the high latitude south Atlantic ocean
