Ears of the Deep, Part IV: Recovering and Deploying Moorings

ABOARD THE USCGC HEALY, ON THE BEAUFORT SEA– Recovering a mooring of any significant size essentially amounts to getting it to the surface and picking it up with a ship using a crane... {Read More »}



“Here Comes the Rain Again”

COLVILLE RIVER, ALASKA-- We awoke this morning to rain, wind, and 35? F temperatures. Immediately the remaining sampling lost most of its appeal, but we inhaled our coffee and oatmeal and staggered forth through the wet brush and tussock tundra... {Read More »}
