Models of magma storage. Part (A) depicts the standard model of magma storage—a single, large body of crystal-poor melt, surrounded by crystalline mush. Although this is the standard 'mush' model, geophysical studies fail to find evidence of this type of magma storage at many active systems.

Looking up at a drone hovering near an open-path methane analyzer mounted on a flux tower. Instruments mounted on both the towers and on the drones are measuring gases emitted from the soil.

 Two UNC mini landers, surrounded by Sablefish (Anoplopoma fimbria) and pink sea urchins, incubate seawater in situ to enable calculations of methane oxidation rates.

In foreground, red-weathering rocks are Hue Shale (oil-prone source rock with is present throughout 1002 Area) and dark gray rocks are Kemik Sandstone (lateral equivalent to Thomson sandstone, main reservoir in Pt. Thomson field).
