This is a reference map of Los Angeles County. Layers include hillshade, major roads, major cities (with populations greater than 125,000 people), lakes, and national forests.
Graduated Symbol Map
This is a graduated symbol map of Toxics Release Inventory in Los Angeles County. Total air emissions consist of the sum of fugitive and stack air emissions; data from 2020.

Map of Kiritimati with lakes shaded (December 2018, this study) or outlined (July 2005, Saenger et al., 2006) according to salinity category (i.e., less than 50 ppt in blue, 50-100 ppt in green, greater than 100 ppt in red). White (black) circles mark locations where water was sampled from the lakes (lagoon) in December 2018, with sizes corresponding to Mn(II) concentration measured, ranging from 0.01 to 0.8 ppb. Measurement uncertainty of salinity is ± 1.0% and analytical uncertainty of Mn concentration is ± 0.320 ppb for lagoon water samples (1 σ; determined from NASS-5) and ± 0.172 ppb for lake water samples (1 σ; determined from CASS-5). Small white stars mark the four lakes that were sampled by this study, Saenger et al. (2006), and Schoonmaker et al. (1985). Bathymetric digital elevation model of the lagoon, developed by applying the Inverse Distance Weighting method of interpolation to measured and estimated points, shows a range of depth from 0.2 - 10.5 m.
