During the eruption, the heat of the lava from the subglacial volcano melts the overlying ice.

They eject it to the surface where it floats, and it is picked up by an autonomous airplane, and it's brought back to the laboratory within 24 hours of the eruption.

They sample the fluids coming out of the sea floor during an eruption, which have the microbes that have never been to the surface of the planet before.
