Fig. 5: Projected monthly trends in surface carbonate and water mass properties.
From: Regional sensitivity patterns of Arctic Ocean acidification revealed with machine learning
Trends shown for each month for the years 2015 to 2050 and are expressed in units per decade for surface calcium carbonate saturation with respect to aragonite (a, ΩA, mol m−3/mol m−3), surface pH (b), sea surface temperature (c, deg C), sea surface salinity (d, p.s.u.). Panels I and II correspond to GFDL-CM4 and panels III–V correspond to GFDL-ESM4. Trends are for the pan-Arctic average (black), Central Arctic Surface Waters (CASW, blue), more general Arctic Surface Waters (ASW, red), and North Atlantic Surface Waters (NASW, purple), and Sub-Arctic Surface Waters (SASW, green) clusters. Black vertical bars denote the standard error of each monthly trend.
