Fort Harrow

As a presence on the page, Thompson is steady and modest, more guide than protagonist, and the most vivid "character" is the photon that wanders through brine channels, fog banks, and plankton blooms. Side voices from the R/V crew and divers flicker in with notes and jokes, but this is not a memoir in disguise, so readers seeking interpersonal drama will find mostly careful observation and a humane, curious voice.

Imagine R. W. Preisendorfer meeting Eli Kintisch: equations in one pocket, polar anecdotes in the other. If you like rigorous field science leavened by quiet humor, this hits the mark, but casual readers may find the instrument-building chapter and calibration tangents a bit heavy. I admired the clarity yet felt little narrative tension, so I dipped in and out rather than reading straight through.

Thompson returns again and again to reciprocity, showing how a single ray path can link micro life to model grids. I loved the recurring thread that measurement is a civic act, a way to "see the sea anew" without handwaving away complexity.

The motif of light as currency lands especially well in the chapters on polar food webs, and the ethical edge of a warming world is handled with restraint. A touch more on indigenous sea-ice knowledge would have deepened the conversation, but the thematic arc still resonates.

What dazzled me was the sense of place and process. Fort Harrow emerges as a small human outpost holding back winter long enough to measure it, while the polar ocean becomes an optical system where ice floes act as lenses, fog as filter, and plankton as reactive dye. The connections to weather, fisheries, and climate are presented with unshowy authority, and the book convinces you that answering the albedo puzzle under drifting ice is not niche at all but central to how the planet works.

The braided structure of shipboard scenes, ice-station vignettes, and primer-level physics mostly works, but a few chapter pivots feel abrupt, like logbook entries stitched after the fact. Thompson is generous with concrete images and patient explanations, and the photon POV gives continuity when the timeline hops.

The prose is clean and often musical, yet the middle swells with instrument minutiae that slow momentum. I wished for a couple of sketches or tables to anchor the hyperspectral bits, though the closing chapters restore flow with lucid summaries of radiative transfer in practice.

A clear, briny travelogue of light that moves briskly from field notes to first principles, turning ice, fog, and plankton into waypoints rather than hurdles.
