A field trip to examine the glacial geology of Discovery Park in Seattle, Washington, leads Callan to contemplate the nature of expertise — and especially his steep learning curve on an oceanographic cruise.
Callan is currently at sea aboard the research vessel Thomas G. Thompson, crossing the North Pacific Ocean from Seattle to Honolulu. In this post, he explores a fascinating aspect of life on the high seas: there is shockingly little life! Explore the scant copepods and albatrosses and reflect on life in the oligotrophic open ocean.
A book review of one of the runners-up for this year’s Pulitzer Prize for general nonfiction: Elizabeth Rush’s chronicle of modern sea level rise.
The Octopus, the Sea, and the Deep Origins of Consciousness is the subtitle of this fascinating, extremely approachable book.

Neat salt “rim” on the edge of the pool… Also note the ~cubic crystals at the bottom of … Read more
The Friday fold is a series of strata underwater near California’s famed “Mavericks” surf break.
Almost a year ago, on my old blog, I brought up the issue of the Suess effect. Go read that post if you don’t remember what the Suess effect is. If you want an executive summary, digest this: The burning of low-14C fossil fuels (because the fuels are old and the 14C has all decayed), … Read more
