Fig. 3: Comparison of Δ200Hg signatures in modeled atmospheric mercury deposition versus measured oceanic samples.
From: Atmospheric source of mercury to the ocean constrained by isotopic model
a Latitudinal variation of Δ200Hg values in atmospheric deposited Hg and oceanic Hg. The boxes represent Δ200Hg observations (interquartile range, P25–P75) in ocean samples, including seawater, particle-bound Hg, sediment, and biota14, aggregated by contiguous latitudes. The bold line in boxes represents the median, the boxes represent the IQR, the whiskers represent 1.5× the IQR, and outliers are represented by dots. The yellow line indicates modeled Δ200Hg signatures in Hg0 uptake by the ocean. The green and red lines represent modeled Δ200Hg signatures in dry and wet deposition HgII over the ocean. The shaded area represents the standard deviation of the latitudinal mean. b Comparison of Δ200Hg values in modeled total deposited Hg with ocean observations. The pink dotted line and shaded area represent the modeled Δ200Hg signatures and standard deviation of total Hg deposited from the atmosphere to the ocean, encompassing Hg0 uptake, dry deposition of HgII, and wet deposition of HgII. c Modeled fraction of the three categories of depositions relative to total atmospheric Hg deposition to the ocean.
