Schematic of Lib Island (A), with stitched panorama of Lib Pond lakeshore edge (B) and an offshore view of Lib Island on boat approach (C). The circle line symbol indicates the orientation of (B) on (A), from north to south. The square line symbol indicates the orientation of (C) on (A), looking from east to the west. Additionally, a regional map of the Marshall Islands with Lib Island is left center.
Figure 2.
Depth profiles of measured water temperature, July 21–23, prior to significant rain event (in orange), with July 24–25, following a significant rain event (in gray scale). Also displayed are pre-rain and post rain averages with horizontal errors bars representing the standard deviation of the average, on either side.
Figure 3.
Depth profiles of measured salinity, July 21–23, prior to significant rain event (in orange), with July 24–25, following a significant rain event (in gray scale). In the top meter of Lib Pond, there was a dramatic decrease in salinity following a series of freshwater precipitation events (Table 2, July 23–24). Also displayed are pre-rain and post rain averages with horizontal errors bars representing the standard deviation of the average, on either side.
Figure 4.
Depth profiles of measured pH, July 21–23, prior to significant rain event (in orange), with July 24–25, following a significant rain event (in gray scale). Also displayed are pre-rain and post rain averages with horizontal error bars representing the standard deviation of the average, on either side.
Figure 5.
Depth profiles of measured dissolved oxygen concentration (A) and percentage (B), July 21–23, prior to significant rain event (in orange), with July 24–25, following a significant rain event (in gray scale). Also displayed are pre-rain and post rain averages with horizontal errors bars representing the standard deviation of the average, on either side.

Water Sample Profiles.
Figure 6.
Panel A: Recorded lake levels spanning the duration of sampling time, with several listed Profiles for reference. Values are reported in cm and on the time scale of seconds following initial lake level reading. Dates are listed above two of the plotted points. Panel B: Lake level readings between July 21–22. Red points correspond to values selected for estimation of lake tidal range.

Lib Pond Sediment Unit Examples.
Representative images of distinct stratigraphic units observed in sediment cores, Units 1–7. Unit 1 and 2 appear in the same image. Unit 1 is the 1–2 cm green layer above the underlying red material, Unit 2. Relative scales have been added to show how much real-world space each image represents.
