Circles denote the location of eDNA samples collected and preserved by the ESP onboard Surveyor during its ~4200-km transit over 29 days (June 10–July 9, 2021) from San Francisco to the Hawaiian Islands. Transit across oceanographic domains, from the California Current upwelling system to the North Pacific Subtropical Gyre, is represented by sea surface temperature (SST) from satellite remote sensing. Shown is the June 2021 average of multiscale ultra-high resolution (MUR) SST Analysis fv04.1, acquired from https://coastwatch.pfeg.noaa.gov/erddap/index.html.

Ocean Planet Exploration Droids: Autonomous eDNA Collection Using An Uncrewed Surface Vessel

by Keith CowingNovember 30, 2024November 30, 2024

The collection of environmental DNA (eDNA) samples is often laborious, costly, and logistically difficult to accomplish at high frequency in remote locations and over large geographic areas.

Rapid Colonization of a Space‐returned Ryugu Sample by Terrestrial Microorganisms

by Keith CowingNovember 25, 2024November 25, 2024

The presence of microorganisms within meteorites has been used as evidence for extraterrestrial life, however, the potential for terrestrial contamination makes their interpretation highly controversial.
